97567d5dd7 feat(core): add a real PTY backend for the Bun runtime (#14046)
* feat(core): separate app launcher and JS interpreter runtime boundary

Establishes the runtime boundary the Bun migration (MYWO-8 S1) needs
before workers, hooks, sandbox helpers and the code-mode host spawn
JavaScript children under a future compiled-app flavor: arbitrary-JS
child processes resolve their interpreter through one accessor (package
manifest first, process.execPath fallback) instead of reading
process.execPath directly, Bun detection has a single seam, and the
app-launcher contract is documented alongside the full call-site
inventory in a bilingual design doc. Adds the same-fixture Node/Bun
regression matrix (stdio framing, exit codes, SIGTERM, IPC channel,
--expose-gc, --input-type=commonjs --eval).

* fix(core): anchor interpreter resolution to the trusted install root

Arbitrary-JS child resolution no longer walks upward looking for a
manifest: the only trusted location is the standalone package root —
the parent of the caller's bundle directory, which must hold both a
manifest.json and the standalone entry marker lib/cli-entry.js — so an
unrelated ancestor manifest in npm, source or SDK layouts can never be
read. Declarations are validated before use: runtime must be exactly
'bun' or 'node', and the interpreter must be an existing executable
regular file; any invalid or missing declaration falls back to
process.execPath without throwing (non-string interpreter, directory,
non-executable file, unknown runtime, absent binary, missing marker).

Adds the regression matrix for unrelated ancestor manifests (npm
bundle and deep SDK layouts), object/number/directory interpreters,
unknown runtime, missing and non-executable interpreters, and the
trust anchor; syncs both design-doc language versions with the
validated contract.

* docs(design): complete the migration inventory handoff

Adds the three interpreter-identity call sites the re-review found
missing from the call-site inventory (hook-command-cgroup launcher,
bwrap-execution and landlock-execution allowlist staging), marks the
unwired rows as owned by the S3 migration sweep, and notes platform
applicability: the cgroup/bwrap/landlock rows are Linux-only
mechanisms validated against the Linux targets of the platform
matrix, while the mem0 and pem rows apply on every platform. Both
design-doc language versions are updated; no product or test code
changes.

* feat(core): add a real PTY backend for the Bun runtime

Under Bun, @lydell/node-pty's wrapper pumps the PTY master fd through a
tty.ReadStream, and Bun surfaces the nonblocking fd's EAGAIN as an error
event instead of "no data yet", destroying the stream and closing the
master: onData never fires, resize fails with EBADF, and the shell tool
and web terminal hang. Reproduced on Bun 1.3.14 and 1.4.0.

getPty() now loads a qwen-bun-pty backend under Bun (non-Windows) that
drives the same native addon directly with a main-thread async fs.read
pump: EAGAIN retries on a short timer instead of erroring, EIO/EBADF end
the pump and close the fd, writes queue through an async fs.write with
EAGAIN retries, and exit waits briefly for the drained fd so data is
never truncated behind onExit. The wrapper's observable contract (env
sanitizing, flow-control bytes, encoding, resize validation, IPty
lifecycle) is mirrored, and the pump starts in the constructor so an
unpumped fd can never hold the event loop open.

Packaging stages the node-pty addon for both runtime flavors, since Bun
installs now load it through this backend. The Windows-under-Bun gate
stays honest (explicit load error), and the runtime-boundary design docs
point at the new backend doc for the mechanism and evidence.

Tests: unit coverage for the backend lifecycle (output, write, resize,
kill, pause/resume, flow control, raw encoding), getPty selection under
Bun/Windows, and a cross-runtime regression that runs the same fixture
through the real getPty() seam under both Node and Bun when a bun binary
is present.

* fix(core): keep PTY exit detection alive while paused

The pinned node-pty addon fires its native exit callback only around
master-fd read activity (isolated-probe evidence, identical on Node and
Bun), so the old pause() that stopped the pump lost onExit entirely:
pause then child exit left the master fd open and the host unable to
drain — the same mechanism behind the XOFF-then-cancel FD residue under
handleFlowControl.

pause() now buffers output into a bounded hold (1 MiB) that resume()
flushes, while reads continue so exit detection rides on the pump.
On end of life the hold is discarded for wrapper parity: onExit arrives
exactly once and the fd is released, but resume-after-exit replays
nothing, matching the wrapper's destroyed paused socket. Docs are
synced to the actual main-thread async fs.read pump (the earlier
worker-threads/blocking-read sketch is documented as abandoned), and
regressions cover pause-at-exit, hold overflow, and XOFF-cancel on both
runtimes.

* fix(core): make the Bun PTY pause hold lossless and exits leak-free

Serializes master-fd reads behind an in-flight guard (a resume chaining
into a read that is still outstanding would cross-observe the shared
64 KiB buffer), holds paused output without a cap so nothing is ever
silently dropped, and routes every end-of-life path through one cleanup
that flushes the decoder, stops the retry timer, closes the master fd
and fires onExit exactly once — including the 500 ms fallback, which is
now ref'd so exit delivery cannot depend on a droppable timer. Pins all
of it with byte/line-exact regressions: no-gap pause/resume storms and
a ~1.9 MB flood resumed byte-for-byte, cross-runtime.

* fix(core): cap the Bun PTY pause hold and terminate on overflow

The lossless pause hold could grow without bound while a consumer
stays paused. The hold now copies chunks into fixed 64 KiB blocks
under a per-pty byte ledger (4 MiB default) inside a process-wide
budget (32 MiB total hold, 8 active ptys, 1 MiB write queue), so the
bound holds for any producer chunk pattern.

Reaching a cap terminates that pty (SIGTERM then SIGKILL) and emits
one structured PtyLimitError — never a success result and never a
fabricated native exit; the real signal death lands only in
stats.nativeExitRecord. Shell executions converge the error into
{error, exitCode: null, signal: null}; web terminals mark the session
failed and the /terminal route sends an error control frame followed
by close 4001. Node behavior is unchanged.

Design docs corrected per review: the drip "kernel corruption" claim
is withdrawn, and exit detection wording no longer overstates when
exits are observed.

* fix(core): harden post-termination pty edges per review

Dual-review follow-ups on the bounded hold: resize() joins write() in
treating a terminated/closed pty as a no-op instead of throwing EBADF
from the addon; a read that was in flight when the limit termination
closed the fd no longer delivers or re-charges its late bytes; and a
resume() replay stops at the first data listener that terminates the
pty, so no held bytes flow after the structured error.

* fix(core): detach pty error subscriptions by observed shape, not assumed Disposable

node-pty's Terminal.prototype.on proxies the listener to its master socket
and returns undefined, while an EventEmitter-based pty (the Bun backend)
returns the emitter itself. The registry stored that return value as a
Disposable and called dispose() on release, so every Bun release, natural
exit, or backend failure path threw TypeError from the route/registry and
could take the whole serve process down (server exit 1, client saw 1006
instead of the explicit close).

Store the subscription return as unknown and detach by observed shape: a
real { dispose } is used as-is, otherwise off/removeListener removes the
listener, and undefined (node-pty's actual return) keeps the previous
no-dispose behavior unchanged.

Covered by two registry unit tests on the mocked shapes plus a real-serve
lifecycle probe (release 4004 / exit 4000 / backend over-limit 4001 with
failed-session reconnect replay, server alive throughout) run under Bun
1.3.14, Bun 1.4.0, and Node.

* fix(core): close Bun PTY fds only after in-flight ops settle

Review round on #14046:

- bun-pty closeFd() ran closeSync() while libuv fs.read/fs.write ops could
  still own the master fd, so the recycled descriptor number could take a
  queued write into an unrelated session. fdClosed now flips and the
  process-wide admission slot is released immediately, but the real close
  is deferred until the last outstanding op settles, with witnesses for
  both the read-held and write-held arms.
- A write-side EIO/EBADF (child already gone) is the expected teardown
  race and is no longer reported, matching the wrapper's swallowed EIO;
  other write errors keep their errno code so the entry classifier and
  getPtyLimitMessage can recognize them instead of escaping as an
  uncaught exception. The pump's emit dispatch runs under try/finally so
  a throwing error listener can never strand the pump.
- The web-terminal registry's pty error subscription no longer re-throws:
  a throw there leaves the backend's fs callback as an uncaught exception
  and kills the serve daemon. EIO/EAGAIN races are swallowed and other
  non-limit errors go to the diagnostic sink.
- Failed sessions no longer count against the web-terminal admission cap,
  and release() no longer fabricates a 143/15 exit frame for them.
- processPtyBudget.maxActivePtys is 64 (headroom over the eight-slot
  web-terminal cap so a full house cannot starve the shell tool), with
  the per-pty vs process-wide cap relationship documented.
- ShellExecutionResult.executionMethod declares 'qwen-bun-pty', its
  error-field contract documents resource-limit termination, and the two
  casts that hid the Bun backend name are dropped.
- getPty tests that assert the Bun arm loads now pin a POSIX platform so
  they pass on Windows hosts; docs and the packaging help text are
  aligned (correct smoke-runtime.js path, boundary-doc PTY row now cites
  the bun-pty fixture, node-pty staging applies to both runtimes).

* chore: re-verify S1 boundary test-file merge resolution with recorded evidence

Empty commit: no code change is warranted by the deterministic gate's
test-weakening rejection. The merge ddc7666b9f resolved
packages/core/src/utils/runtime-info.test.ts and
packages/core/src/utils/runtime-boundary.node-bun.test.ts to main's
reviewed versions from #14036 (2eab3cc431), replacing the older
stacked draft copies this branch carried while the prerequisite was
unmerged. Both files are byte-identical to origin/main (empty merge-
base diff: this PR no longer modifies them), and main's versions are
strictly richer (19/16 vs 16/15 expect() calls), so no assertion
coverage is lost. The per-file evidence is recorded in the round's
test-weakening.json; restoring the drafts would revert the reviewed
suites and re-introduce the stacked duplicates the merge correctly
eliminated.

* fix(core): preserve PTY failure output and bounded settlement

* fix(core): deliver reaped PTY exits on limit trips, replay failed scrollback

Review round on the Bun PTY backend:

- terminateResourceFailure no longer signals a pid it already reaped
  (pendingExit parked): the real exit is delivered and the structured
  limit error reported, instead of SIGTERM/SIGKILL at a recycled pid.
- The failed-reconnect branch of the terminal WS route replays the
  retained scrollback through the backpressure guard before the error
  frame, matching the exited path.
- QWEN_PTY_ACTIVE_LIMIT no longer claims a termination that never
  happened, and acceptedBytes stays a byte count (0 at refusal).
- sanitizeEnv also applies when options.env is omitted, matching the
  wrapper's resolved-env rule.
- The arithmetically unreachable paused-hold-segments cap is deleted.
- Tests: the live-failure route test now reaches a live session; the
  registry limit test is parametrized over both limit codes; the
  paused-exit fixture gains a withheld-tail oracle so it cannot pass
  without a real pause; the bounded-hold tests get afterEach failure
  isolation; the process-wide write-queue budget is exercised; and the
  stale throw-propagation assertion is reconciled with the deliberate
  reportListenerError containment (un-breaks the core test lane).

* fix(core): refuse oversized terminal input before the pty cap

* fix(core): park paused PTY reads at the hold cap instead of killing the tree

Under the Bun backend the shell tool passes handleFlowControl: true, so a
single Ctrl+S (XOFF) byte calls pause(). The pump kept reading into the
paused hold and, once the 4 MiB per-pty (or 32 MiB process-wide) hold was
full, terminated the child process tree with QWEN_PTY_OUTPUT_LIMIT. During
a flood that killed the command about a second after one keystroke.

Size each paused read to the room left in the hold and, once there is
none, stop issuing reads until resume(). The kernel pty buffer then fills
and the child blocks on write, which is the backpressure the node-pty
wrapper's paused socket applies. Nothing is dropped or killed, and
resume() replays the hold and restarts the reads; pty.stats.readParked
exposes the state. QWEN_PTY_OUTPUT_LIMIT and the paused-hold limit kinds
are removed together with the consumer branches that handled them. The
write-queue and admission limits are unchanged.

While parked, a child that dies with output undrained may only finish
exiting on macOS once the master is read again, so the shell tool's
cancel now calls resume() before it signals the process group.

The design docs also get the live-pty cap right (64, not 8) and no longer
describe a block-count cap that the hold never had.

* test(core): run the PTY drain-window witness on Linux only

The real-child test for a write-limit trip after the native exit relies
on a HUP-ignoring grandchild keeping the pty slave open after the session
leader exits. macOS ends the master side right away (a plain-pty probe on
Darwin reads EOF about 70 ms after the leader exits), so the pump closes
the fd before the write and the case failed 3/3 there. Skip it off Linux;
bun-pty-failure-order.test.ts still pins the same guard on every platform
with a mocked native exit.

* fix(core): reap a PTY's whole session on a resource-limit termination

terminateResourceFailure signalled only the leader and the leader's
process group. An interactive shell runs each foreground job in its own
group, so a job that ignores SIGTERM and SIGHUP outlived the termination:
the failure was reported and the budgets refunded while the job kept
running, reparented to init. Reproduced on Linux and macOS.

List what the pty owns with ps while the leader is still unreaped: its
descendants, plus every process in its session (Linux sid) or on its
controlling tty (macOS tdev). Signal each of them as well as the group.
The SIGKILL pass after the grace period lists the tree again. It keeps
an earlier member only while that member's start time still matches, so
a recycled pid is never signalled. It reuses the scope only where the
scope still names the session: macOS drops the tty with the leader, and
Linux keeps the sid unless the pid now leads a new process.

The web terminal registry's killPtyTree already walked the same ps
listing; both now share collectPtyProcessTree.

* test(core): tolerate the pty's CR jitter in paused-flood oracles

macOS's pty driver occasionally inserts an extra CR before LF; a plain script(1) probe reproduces it without this project's code. The paused-flood tests compared the stream byte-for-byte and waited for pausedBytes to equal the logical byte count, so a jittered stream could never satisfy the predicate.

Wait for pausedBytes >= the logical size, derive the process-wide case's expected hold from the observed hold, and compare the resumed stream with runs of CR before LF collapsed. Every line's content, order and count is still asserted, so loss and duplication remain caught.

2eab3cc431 refactor(core): separate CLI launcher from JS interpreter (MYWO-8) (#14036)
* feat(core): separate app launcher and JS interpreter runtime boundary

Establishes the runtime boundary the Bun migration (MYWO-8 S1) needs
before workers, hooks, sandbox helpers and the code-mode host spawn
JavaScript children under a future compiled-app flavor: arbitrary-JS
child processes resolve their interpreter through one accessor (package
manifest first, process.execPath fallback) instead of reading
process.execPath directly, Bun detection has a single seam, and the
app-launcher contract is documented alongside the full call-site
inventory in a bilingual design doc. Adds the same-fixture Node/Bun
regression matrix (stdio framing, exit codes, SIGTERM, IPC channel,
--expose-gc, --input-type=commonjs --eval).

* fix(core): anchor interpreter resolution to the trusted install root

Arbitrary-JS child resolution no longer walks upward looking for a
manifest: the only trusted location is the standalone package root —
the parent of the caller's bundle directory, which must hold both a
manifest.json and the standalone entry marker lib/cli-entry.js — so an
unrelated ancestor manifest in npm, source or SDK layouts can never be
read. Declarations are validated before use: runtime must be exactly
'bun' or 'node', and the interpreter must be an existing executable
regular file; any invalid or missing declaration falls back to
process.execPath without throwing (non-string interpreter, directory,
non-executable file, unknown runtime, absent binary, missing marker).

Adds the regression matrix for unrelated ancestor manifests (npm
bundle and deep SDK layouts), object/number/directory interpreters,
unknown runtime, missing and non-executable interpreters, and the
trust anchor; syncs both design-doc language versions with the
validated contract.

* docs(design): complete the migration inventory handoff

Adds the three interpreter-identity call sites the re-review found
missing from the call-site inventory (hook-command-cgroup launcher,
bwrap-execution and landlock-execution allowlist staging), marks the
unwired rows as owned by the S3 migration sweep, and notes platform
applicability: the cgroup/bwrap/landlock rows are Linux-only
mechanisms validated against the Linux targets of the platform
matrix, while the mem0 and pem rows apply on every platform. Both
design-doc language versions are updated; no product or test code
changes.

* style: apply prettier to the bun boundary docs and runtime tests

Fixes the failing Lint & Static lane: `prettier --experimental-cli
--check .` ([email protected], the lockfile resolution) rejects the two
bun-runtime-boundary design docs and the two runtime-info test files
introduced by the runtime boundary change. Formatting only — markdown
table alignment, emphasis markers and code line wrapping; no content
or behavior changes.

* test(core): harden runtime boundary fixtures and document validation scope

* test(core): reject stderr errors while awaiting fixture identity

* test(core): expose Bun version and complete runtime call-site inventory

ChiGao 5aae8991be fix(cli): keep the OpenTUI composer caret steady (#13693)

asks the terminal for a blinking block. Between blinks the caret is gone,
which reads as the input having lost focus while typing. Pin the shape and

ChiGaoandShaojin Wen 415726c28c fix(cli): window the OpenTUI transcript to fix the blank-screen resume (#13669)
* fix(cli): window the OpenTUI transcript so a long resume cannot blank the screen

@opentui allocates one native TextBuffer per mounted text element, and the
OpenTUI transcript mounted every history item at once. Resuming a session of a
few thousand records exhausted the process, and the resulting throw was silent:
it lands inside a React host-instance creation, @opentui/react's own boundary
catches it, its red-text fallback calls a jsxDEV the bundle does not provide and
throws too, and React unmounts the whole root, leaving an empty alternate screen
with a live process still accepting input.

Mount only the items near the viewport, budgeted in rows rather than items, with
spacers standing in for the rest so the scroll geometry still spans the whole
session. Estimates mirror the values the ink transcript already uses, real
heights are measured per item id and survive unmount, and the scroll position is
sampled on the renderer's frame event so an idle terminal costs nothing.

Also wrap each mounted item in an error boundary whose fallback renders nothing.
A failed item now costs one row instead of the whole UI, and the error reaches
the OPEN_TUI_TRANSCRIPT debug log.

The session picker's preview pane is clipped and does not scroll, so the view
takes an initial anchor and the preview passes 'top'.

* fix(cli): stop the transcript window moving the reading position

Three defects in the windowing's scroll handling:

The height table was cleared on a width change, which renumbered every row
offset underneath a scroll position that is itself counted in rows, so a
resize moved the visible turn by more than a hundred. The entries a resize
actually invalidates are the mounted ones, and the next frame re-measures
those.

A height correction was written back through the sticky-aware scrollTop
setter. No correction is owed: an item the measuring loop can see is already
painted at the height just read from it, and both spacers derive from offsets
a change inside the window leaves alone. Writing one moved the reading
position and, at the tail, took the shell's bottom pin off for the rest of
the session.

The position was sampled only on the renderer's frame event, which fires
after the paint, so an absolute jump — a scrollbar track click or a thumb
drag, which can land anywhere in the transcript — painted one spacer-only gap
first. The scroll bar emits a public change event synchronously before that
paint; subscribing to it covers every scroll path.

Also: the host-less session preview now follows the height prop across a
resize instead of seeding its viewport rows once at mount; the item failure
log carries the component stack and the error stack, matching ink; the two
windowing options no caller ever set are gone, so the cap and the overscan
are pinned by the tests that exercise them; and the cap's binding condition
is stated correctly in the code and in both design docs.

Adds a scroll-host harness so the frame-driven half is reachable from jsdom
at all, and five tests over it, each mutation-proved against the defect it
pins.

* docs(cli): record the two windowing follow-ups the review named

The bundle-level jsxDEV escalation Decision 8 compensates for at the item is
still live for every other subtree, and a window-only move re-executes every
mounted item's render path. Both are named in the design rather than left to be
rediscovered.

* fix(cli): measure transcript items by identity and settle pulled-in rows

Each mounted item now registers its own node under `(kind, id)` instead of
being recovered from its position among the transcript root's children, so
the tool and task cards one subagent call mints no longer overwrite a single
height slot, and the item key no longer collides as a React key either. The
rows recorded are Yoga's computed height rather than the reported one, which
is clamped to a row and would permanently charge a row to an item that
paints nothing.

An upward window move pulls in items whose spacer rows were charged at the
estimate, so the frame that first measures them now subtracts what they
turned out to cost from the scroll position — guarded to fire only strictly
above the tail, where the reader's own scrolling has already released the
shell's bottom pin. Measuring an item that was already mounted still owes
nothing. Measuring also runs when no scroll host is found, so the session
picker's preview records real heights too.

* docs(cli): state the measured mutant victims in the windowing design doc

* fix(cli): settle a transcript row whose recorded height went stale off-window

The settlement for a row the window pulls in above the viewport only fired
for an identity the height table had never seen. A row measured earlier,
evicted, and then re-measured at a different height moved the offsets under a
scroll position nothing re-anchored, so the page lurched on every wheel tick
after a terminal resize or ctrl+O.

Settle on the charge rather than on first-ever measurement, spend the charge
on the measurement that answers it, and never charge an identity the previous
commit already had mounted — which is what a `task-end` splice above the
window would otherwise do, since it shifts the index space the charging loop
walks while the identities on screen stay put.

* docs(cli): keep the windowing design doc true about the stale-height settlement

Decision 5 said the frame that *first* measures a pulled-in item settles it,
and that the charge is always the estimate; the settlement now spends a charge
on the measurement that answers it and never charges an already-mounted
identity. The mutation ledger named ten tests on the scroll-host harness and a
suite total that both moved.

ChiGaoandchiga0 bc682d1754 fix(cli): give bare ↑/↓ back to input history in Virtualized History (#14016)
#12518 routed a bare ↑/↓ on an empty composer to transcript scrolling in VP
mode, on the theory that terminals without SGR mouse reporting deliver the
wheel as arrow-key sequences. The composer is empty at rest, so the fallback
fired on every deliberate ↑/↓: input history became unreachable from the
arrow keys and only Ctrl+P / Ctrl+N still recalled it.

That also contradicted the contract the project had already settled on —
#4942 ("scroll with wheel or Shift+↑/↓ anytime, type messages anytime"),
#5159 (closed with a docs workaround rather than by reassigning the keys),
ui.useTerminalBuffer's own description, and both keyboard-shortcuts.md and
troubleshooting.md, none of which #12518 updated.

Gate the fallback behind a new opt-in ui.arrowKeysScrollTranscript (default
false). Bare ↑/↓ walk input history again everywhere by default; a terminal
that genuinely cannot report the wheel turns the setting on and gets
#12518's behaviour verbatim, with Ctrl+P / Ctrl+N for history. The opt-in
keeps every guard #12518 added — empty composer, transcript actually
overflowing, ↓ still yielding to descendFromComposer — and non-VP mode is
untouched.

Docs now name the setting as the alternative for the tmux trackpad case.

fe2dd7f6d2 fix(cli): match ink's OpenTUI popup geometry and completion truncation (#12559)
* fix(cli): match ink's popup geometry and completion truncation in OpenTUI

Every popup now renders inside a fixed, clipped region sized the way ink
sizes it, so a dialog ink stretches fills the viewport and a picker taller
than the region clips instead of pushing the composer off screen.

The completion dropdown truncates an over-long argument hint and source
badge into the columns the label leaves, splitting the overflow between
them in the proportion ink's flex shrink produces.

The wire-API step of the provider wizard reads its cursor out of the same
read that armed the key handler, so an arrow and an Enter arriving
together save the item the arrow moved to.

* docs(design): record the parity matrix re-run on the merged tree

The two-arm comparison was cut before main was merged into the branch, so
note that the after arm was re-run on the merged tree and that every
checkpoint verdict carried over.

* fix(cli): budget the approval-mode dialog and keep the picker shrink across resizes

Review round on #12559:

- OpenTuiApprovalModeDialog takes the popup region's row budget and ports
  ink's derivation: shed the spacer row below 9 rows, the footer hint
  below 10 (12 with the workspace warning), and window the mode list
  behind scroll arrows with what remains. The mount now forwards
  availableTerminalHeight to it, as it already did for theme/settings/model.
- Session-picker branch keys carry the box size so a terminal resize
  remounts the host node: the renderer's width/height setters clear an
  explicit flexShrink back to 0 and its reconciler never re-applies an
  unchanged prop, so the shrink was silently lost on the first resize.
- The shared dialog shell drops its top margin and asks to shrink, like
  ink's dialogs; marginTop + flexShrink: 0 overflowed the region at
  <= 24-row terminals and clipped the auth dialog's bottom rows.
- STATIC_EXTRA_HEIGHT is exported from layoutUtils and shared by
  AppContainer and the OpenTUI shell instead of two literals; the region
  test derives its expectation from the constant.
- truncateToWidth composes clipToWidth so the grapheme-boundary rule lives
  in one place.
- The parity design doc's stale follow-up pointers, pre-merge matrix claim,
  this-pass/that-pass mix-up and unconditional popup-region wording are
  corrected, and the confirmation-slot / picker-window / constrainHeight
  divergences are recorded, in both languages.

* fix(cli): address the second review round on the OpenTUI parity sweep

The approval dialog's row budget now mirrors ink's own height constants, so
its mode list, footer hint and workspace warning reserve the rows ink
reserves instead of a number derived from the region alone.

The help overlay budgets from the popup region rather than the raw terminal
height: the region's derivation already accounts for the banner, the status
bar and the composer, none of which it renders while a dialog is open. The
constant that described rows the overlay does not draw is gone, replaced by
the overlay's own chrome count, which brings the command window to the
eighteen rows ink fixes on a forty-row terminal.

The completion dropdown strips ANSI escapes before measuring a row against
its column budget. This renderer has no content-level ANSI handling, so
escape bytes were charged as visible columns and a cut could land inside a
sequence.

The four dialog frames that pinned their own top margin now shrink with the
region instead, matching the frame rule the session picker already follows.

Tests assert the shared popup budget constant on both legs so neither can
drift, and the design doc records what was measured, what still holds its
own height, and what no executable check covers yet.

* docs(cli): stop citing the settings dialog as a dialog that windows itself

It receives the row budget and reads no height at all, so the mount's prop
comment and the parity doc both sent a reader to a hollow precedent. The
comment now names only the three bodies that consume the budget, and the
doc lists the settings dialog's eight-item window among the unwindowed
tails that have no reveal path.

* docs(cli): attach the withdrawn-census disclaimer to the split it withdraws

"That split" sat directly after the 258/288 row tally, so the sentence read as
attributing to the coverage boundary a withdrawal it never makes. It now names
the seventy-three/fifty-eight checkpoint split and states that the row counts
fall with it.

* fix(cli): re-clamp opentui list windows on resize and charge the refusal ahead of the warning (#12559)

* fix(cli): surface the refusal and close the zero-row key paths in opentui dialogs (#12559)

- Paint the trust-gate refusal on the one row region six can pay (margin
  shed), and carry it in the title's subtitle where no row can be charged
- Let a zero-row list budget borrow the frame's blank bottom padding row
  (listRows < 0), restoring the row ink and the pre-budget code paint
- Refuse arrow keys beside Enter while the window paints no rows, so a
  highlight move cannot retarget the scope invisibly
- Expire a refused number prefix on the same clock a live entry flushes on
- Let the settings list budget reach zero and gate its hand-rolled keys;
  budget the settings scope step from the region and hand it to the hook
  and the render
- Lay the settings search box out as the one text row the chrome budget
  counts (flexDirection=row)

* fix(cli): keep the opentui refusal visible on narrow rows (#12559)

- DialogTitle: where the title run alone fills the content width it now
  yields half the row to the subtitle instead of suppressing it, so the
  trust-gate refusal still paints at 24 columns and below instead of a
  rejected Enter reading as a dead key (R7-1)
- Pin the session picker's width-only resize remount for the list and
  preview boxes, the unwitnessed half of the folded key (R2-5)
- Correct the design doc: scope the withdrawn-split sentence to the census
  it is true of (R3-10), qualify the help overlay's no-unused-rows claim
  at the cap (R3-13), and record the picker window's measured symptom —
  the last item's metadata row, not the scroll marker (R5-9)

* fix(cli): close the zero-row paint and key gaps in opentui dialogs (#12559)

- Shed the workspace-warning box's margin when its charge caps at one
  row, so the row paints the advisory instead of a blank (charge-neutral:
  marginTop + height still sums to warningRows), mirroring the refusal box
- Guard the settings list's re-follow effect against a zero-row window
  and gate both scroll arrows on a painted window, so an empty list no
  longer paints ▲/▼ around nothing
- Exempt the keys that address no row from the zero-row key guard — the
  restart prompt's r, up from the top row into the search box (thence the
  tab bar), and type-to-search — while the k/j highlight aliases and a
  digit on a numeric row stay refused as the row keys the chain reads
  them as

* fix(cli): charge dialog chrome the rows it paints and budget the picker, permissions, and sized bodies (#12559)

* fix(cli): charge region-mounted dialogs the rows they paint (#12559)

The session picker's window floored at one row, keeping Enter and Space
committing a cursor row nothing painted on a short terminal; it floors at
zero now, with zero-window refusals on those keys. DialogFrame keeps its
natural height so the region's clip cuts a contiguous tail instead of the
renderer squeezing list rows to zero mid-list, while Shell splits: static
bodies (auth, trust, the placeholders) shed blank rows like ink instead of
clipping their border. The permissions search box lays out as the single
content row its charge assumes, and the runs the budgets charge as one row
(rule and directory labels, tab-bar hints, search queries, footers, the
settings row label) are clipped to the charged width, with the workspace
description's wrapped rows charged instead. The settings list pays for its
scroll arrows only when they paint. The mount hands the region budget to
every dialog leg, and the hooks, extensions, theme, effort, output-style,
permissions scope, MCP tool/resource and arena pickers window from it —
replacing the constants that overran short regions while keys kept
committing the clipped rows.

* fix(cli): opentui dialog windowing and sanitization from the #12559 R1 review

Seven follow-ups from the R1 review, each pinned by a test that goes red
when its guard is removed:

- The completion row's hint/badge/description sanitize through a new
  sanitizeTerminalLine: the same ANSI/VT/C0/C1 strip as before, plus the
  bidi override/isolate range, and the TAB/CR/LF the input buffer keeps
  flatten to spaces so a newline can no longer paint a second physical
  row the width budget never charged.
- The /auth wizard frame is unshrinkable again: its radio lists do not
  window, so a shrinkable frame let a short region squeeze them
  mid-rows while Enter stayed live. The static /auth summary and trust
  bodies keep `shrinkable` (F5-1).
- The /skills scrollbox windows its twelve-row body from the region
  budget (the frame chrome takes six rows first), so the unshrinkable
  frame no longer paints its border past the region's bottom edge;
  Decision 71's sized-body count and the resolved Follow-ups entry are
  corrected in both design-doc languages.
- The /mcp tool and resource windows follow the cursor from state
  (BaseSelectionList's rule) instead of being re-derived from the cursor
  on every render, so a hover can no longer shift the window under the
  pointer and make a click open a different row.
- The /hooks list labels clip to the one physical row their window
  charge pays for, and regionListWindow gains direct unit tests (it had
  none).
- The unreachable zero-row Enter guard inside useDialogSelect's return
  branch is deleted; the outer guard already covers every key.
- The /arena p/d zero-row guard refuses only opening a pane; an open
  preview or detailed-diff pane can always be closed again.

* fix(cli): opentui charge honesty and auth wizard floor from the #12559 R4 review

The window charge must equal what the frame paints. Round 4 found six
dialogs where the two still disagreed, and a first-run trap the R3 fix
introduced:

- /auth wizard: below a thirteen-row region the full main chrome left the
  list zero rows while Esc was refused, trapping the first-run setup. The
  rule and the terms block now shed before the list loses its last row, and
  the zero-row refusal covers only what even the shed chrome cannot pay.
- /effort and /output-style charged a flat 7 that double-counted the
  title's margin; the footer hint and the note are now measured like the
  title, returning a row the region could always pay.
- /resume and /delete budgeted the header, search and filter rows off the
  bare region width with UTF-16 lengths; the budgets now come off the
  padded row (boxWidth - 4) and measure display columns.
- /mcp server rows clip the status and invalid-tools runs to the one row
  the row is charged, and the debug hint clips likewise. A detail value
  taller than the whole window (a parse-error dump) made the paint
  predicate unsatisfiable, so the Error row never painted; the charge now
  caps at the window minus the rows below and the paint clips to the same
  rows, keeping the actions reachable.
- /arena select clips each detailed-diff line, the agent stats run and the
  frame hint to the columns their row charge pays, and the task line to
  the width it owns.
- /theme clips the scope message so the title row stays one row.
- /permissions' add-rule scope step budgets its label clip from the framed
  width (areaWidth - 4), not the bare region.
- The session picker's disabled-row hint now survives the meta clip (the
  leading segments give way instead of the explanation).
- Design doc: the merged-tree re-run reads 133 checkpoints like the
  matrix, the dangling "two empty ones" gains its antecedent, the /mcp
  follow-up names the genuinely unwindowed sized bodies, and the picker
  entry stops claiming ink derives the identical window from raw rows.

Each new guard carries a red-witness test, verified by mutation probe.

* fix(cli): opentui preview pane budget, row clip, and title charge from the #12559 R5 review

* test(cli): keep the cli suite off the operator's ambient QWEN_HOME (#12559)

The autofix verification gate runs the cli suite with the runner's real
HOME and no QWEN_HOME, so the fail-closed operator-settings read in
execution-sandbox-settings.ts hits the runner's real
~/.qwen/settings.json. That file holds invalid JSON on the shared autofix
runners, and 13 test files / 389 tests that load settings or start a
serve stack failed with a FatalConfigError (exitCode 52) they have
nothing to do with, rejecting the R5-review commit 5ebd14b350.

test-setup.ts already strips other operator-ambient state
(QWEN_RUNTIME_DIR, QWEN_REVIEW_SANDBOX, ...); pin QWEN_HOME to an empty
per-file temp directory there so the suite never reads the operator's
settings. settings.test.ts builds its resolution assertions on a mocked
os.homedir and so needs the ambient variable deleted at module scope.

Red/green with a poisoned $HOME/.qwen/settings.json ("X\n") and a
gate-shaped env (env -i, no QWEN_HOME): session.test.ts fails 42/42 with
the identical FatalConfigError stack pre-fix and passes 42/42 post-fix;
the gate's exact command (--changed origin/main with the load clamps)
runs the full suite green (39860 tests) against the same poisoned home.

Same fix as 5068bd91cf on fix/managed-12693-review-correctness (#13332),
applied here so this branch's gate stops failing on the runner condition.

* fix(cli): opentui dialog floor and charge fixes from the #12559 R6 review

  the frame's content width instead of charging flat rows, so a wrapped run
  (the 88-column modelProviders URL) can no longer grow the unshrinkable
  frame past the region
- arena start: clear the too-few-models error on the next key, so the
  zero-row window it causes cannot permanently refuse the Space that would
  satisfy it
- arena select: sanitize the preview pane's title, approach and file runs
  and the detailed-diff title before measuring and painting, and charge the
  diff pane's title the rows it wraps into like the preview title
- auth: shed the main list's margin row when even the shed chrome pays no
  item (region 7 paints one provider again), and let Esc close the main
  view when its window paints nothing instead of wedging on the
  must-connect gate
- mcp: pin the --debug hint below the windowed server list, paid two rows
  out of the region budget, so it survives the overflow it exists for
- settings: clamp the scroll offset when the window grows, so a grown
  region paints all the rows it pays for

* fix(cli): stop short dialog regions from painting panes they cannot pay

Two dialogs charged rows for a pane without checking that the region could
pay the pane's own chrome, and then clamped the resulting deficit away with
Math.max(0, ...). The frame is unshrinkable inside the clipped region, so
the overflow came back as the clip taking rows from the list the user still
needed.

The MCP dialog's --debug hint took its two rows whenever the body window had
at least two, leaving the server list zero: no server painted while the step
header still counted them, and the zero-row refusal killed the arrows and
Enter with it. The hint now only spends rows the list can spare.

The arena select dialog priced the detailed-diff pane's margin and title
rows, then painted the pane even when the region could not cover them. The
pane now does not paint at all in that case and charges nothing, matching the
rule the sibling preview pane already follows.

* fix(cli): clip the arena select prompt to the row its charge pays for

The select dialog charges its chrome a flat twelve rows, pricing the
"Select a winner" prompt at one. At thirty-three columns the prompt wraps
once the frame's content is narrower than that — any terminal under 43
columns — so the unshrinkable frame painted one row past the region and the
clip took the bottom border and the hint row instead of the list's tail.

Clip the prompt to the frame's content width, the way the task line above it
and the frame's own hint already do, rather than raising the charge: a
thirteen-row charge would leave the fourteen-row region at width 40 unable to
paint any agent row at all.

* fix(cli): derive dialog list-window chrome from measured runs

The window budget's chrome was a hand-counted constant per dialog, so
every chrome text run that wraps at a narrow terminal was charged one
row while painting two and the unshrinkable frame grew past the region
— each review round kept finding another entrance. regionListWindow now
takes a DialogChrome (fixed rows no run can wrap into, plus every chrome
text run measured by wrappedRows at the width it paints at), and the
nine call sites plus the inlined mcp/auth/misc budgets enumerate theirs:
theme title/footer and item labels, extensions status/footer/tab hint,
hooks footer, permissions scope title/question/footer, mcp per-step
header and footer, and the Shell title via shellBodyChromeRows. The zero
floor is unchanged. Design doc decision 72 records the rule.

* fix(cli): keep every painted dialog row inside the region that pays for it

A dialog mounts in a fixed-height, clipped region while its frame keeps its
natural height, so a row the budget does not charge is a row the clip takes
off the tail. Charge the runs that wrapped: the theme pane now measures the
footer hint instead of assuming one row, the model-IDs step windows its
recommended list from the region like its sibling steps, and the arena sheds
an advisory block rather than the interactive rows it would cost. Rows
charged one physical row clip to the columns they own instead of wrapping.

Keys are refused the rows nothing painted. Enter re-checks the window it
commits against, so a held arrow whose burst outruns the scroll offset cannot
persist an off-screen row, and the numeric flush re-checks too.

ChiGao 74b5eb9e6d chore(cli): bump the OpenTUI renderer to 0.5.10 (#12321)
* chore(cli): bump the OpenTUI renderer to 0.5.11

The upstream release makes wrapped layout byte-accurate, which removes an
extra leading space on wrapped paragraph continuations and stops greedy
wrapping from breaking a line short. Both were visible divergences from the
incumbent renderer. It also adds line breaking between CJK characters.

* chore(cli): pin the OpenTUI renderer to 0.5.10 and gate the wrap fix

0.5.11 stops printing the markdown link target text, which is the only
thing link-click.ts can match on to implement click-to-open, so the
newer release silently breaks that path. 0.5.10 carries the same three
wrapping fixes without that regression and declares no engines floor.

Add a wrap-parity golden covering the paragraphs whose framing drove the
bump, wired into the tui-parity workflow, so re-pinning to 0.5.8 or
accepting a later release that regresses wrapping turns CI red. Verified
in both directions: green on 0.5.10, all three cases red on 0.5.8 while
the pre-existing parity scripts stay green there.

Also correct the two places whose claims measurement disproved — the
link-click header comment asserted no 0.5.x release emits OSC 8, and the
migration design doc still called 0.5.8 the pinned version — and record
in the parity sweep that whole-row divergence narrowed rather than
closed, since the rows carrying these paragraphs also carry two
unresolved divergences.

ChiGao 49dfc87906 fix(cli): close the remaining OpenTUI parity gaps against ink (#12309)
The OpenTUI renderer is meant to stand in for ink, so a divergence is a
defect in the port rather than a difference of taste. This sweep drives
both renderers through the same scripted sessions and closes what the
frame-by-frame comparison surfaced.

The ink theme was never applied at all, so ui.theme, /theme and the
light/dark probe were inert here; the session list behind /resume and
/delete was one hand-rolled line per row with no checkbox column and no
preview, so a bulk delete could only ever remove the row under the
cursor; several dialogs still read the cursor and the text buffer of the
previous render, which loses keys whenever one stdin read carries more
than one; tool cards dropped their inline arguments, folded the status
glyph into the title and ignored the settings that collapse them; and a
few settings had no read site in this renderer at all.

ink's own behaviour is untouched — the ink-side edits only export what
the port now shares instead of duplicating.

ChiGaoandQwen-Coder b0afb6c196 fix(cli): close twelve OpenTUI parity gaps found against ink (#11806)
* fix(cli): draw OpenTUI tool confirmations inline as ink does

ink renders a tool confirmation inline in the transcript, as a sibling
directly below the row of the tool call that is waiting, with no border, no
title row and no navigation hint; the awaiting call is marked by an arrow
appended to its own row. This renderer instead boxed the same content at
full width, gave it a title, added a separate row announcing that the call
was awaiting approval, and kept a hint about navigating a list. Approving a
command therefore read as answering a modal rather than as continuing the
transcript, and the box pushed the question and its options several columns
past where ink puts them.

The border, the title and the hint are gone. The body, the question and the
outcome list now sit at the columns ink uses, the awaiting arrow rides the
tool card's own row instead of taking one, and while a call is parked the
spinner swaps to ink's waiting phrase and drops the elapsed-time, token and
cancel suffix — there is no in-flight request to cancel and no tokens to
count. That waiting row is rendered only for a tool confirmation: the MCP
startup approval, the shell gate and the action confirmations all arrive
while idle, where ink's indicator renders nothing, and the captured frames
agree.

The row budgets that reserved space for the removed chrome shrink with it.
Those bounds turn out to be inert at the viewport heights the harness uses,
so the change was verified against ink's own frames at a hundred columns
rather than against the arithmetic: the confirmation's row sequence now
matches ink line for line. What still differs is where the block sits
vertically — this renderer anchors it to the bottom of the viewport while
ink flows it straight after the tool row — which is a separate known
divergence and is not addressed here.

* fix(cli): let a plain-text tool update replace OpenTUI's structured payload

A tool card prefers a structured payload over its flattened text and does so
unconditionally, which is what lets a shell run paint a styled token grid, a
diff render its coloured lines and a todo write render its status list. The
history fold that feeds the card only ever added those payloads, though, and
never cleared one, so the preference could outlive the payload it was chosen
for.

A shell command hits exactly that: it streams styled output while it runs and,
if the stream then trips binary detection, the accumulated output is replaced
by a plain string. The card kept the last grid it saw and showed it forever,
including after the call settled, so the user was told nothing about the
binary output and never saw the byte counts that followed. The same shape
applies to any tool whose display changes kind mid-flight, since a result
carries at most one structured payload.

Each event carries the whole display, so the structured fields are now derived
from the event rather than accumulated onto the card. The three producers of
these events all pick the structured form or the flattened form and never emit
both for one result, and the trailing flush that could have delivered a late
update after completion is cancelled before the call returns, so nothing
regains a payload that a later event legitimately dropped. The egress
disclosure keeps its existing sticky behaviour: it is an additional notice
under the result rather than an alternative rendering of it, and it takes no
part in the card's preference.

* fix(cli): port ink's question dialog to OpenTUI in full

The ask_user_question confirmation had been reduced to its literal options: no
free-text row, no description under any option, no digit keys, and a full-width
box around a dialog that ink draws inline under its own transcript entry. A
selection therefore cost a navigation and a confirmation instead of one
keypress, and an answer the model had not happened to invent could not be given
at all.

The dialog is now ported whole from ink's own component: a chip row of question
headers with a review-and-submit tab after them, numbered options carrying
their descriptions, multi-select checkboxes, and a trailing free-text row that
takes a bracketed paste of its own, since the composer that would otherwise
consume one is unmounted while a confirmation owns the screen. The chip row's
width is derived rather than guessed, by reusing the water-filling helper ink
sizes it with and subtracting every cell the row spends outside the header text
from the width a tool confirmation actually gets in the transcript.

One divergence is deliberate. ink subscribes to Enter twice on the free-text
row, once from the dialog's key handler and once from the input widget it
mounts, and its key layer has no focus stack to arbitrate between them, so a
typed answer advances two tabs and silently skips the question after it. That
was observed on a real run rather than inferred: the acceptance leg timed out
waiting for a question that was never drawn, and the review tab reported it as
unanswered. Every key here goes through one handler, so Enter advances exactly
one tab. Fixing it in ink would move the baseline this sweep measures itself
against, so the defect and the divergence are both recorded in the design doc.

Typing also builds each next value from a mirror written synchronously rather
than from the value the registering render captured, because keystrokes out of
one pty read can share a React batch and only the last of them would otherwise
survive. Removing the mirror fails exactly the test that pins it, with a
five-character answer rendering as a single character.

The acceptance harness needed a fix of its own before this could be measured.
It waited on the byte stream, and a renderer that repaints only the cells that
changed never puts a line edited in place into that stream as one contiguous
string, so a leg timed out on a screen that was already correct. Waits now poll
the reconstruction as well, less often than the stream because reading it
flushes the pty and walks the whole buffer.

Verified on a real machine against ink over eight checkpoints of a
three-question dialog with a multi-select and a twenty-character typed answer,
plus the two checkpoints of the single-question scenario. Every dialog row
matches on text and on indentation, including the mark appearing on the header
chip as soon as its free-text box is checked and the review tab dropping the
cancel clause from its hint. The rows that still differ on those frames are the
long context-file path wrapping at a different column, the spinner's braille
phase, and this renderer's deliberately reworded update notice. Across the
whole matrix the single-question pair drops from twelve and eighteen differing
rows to four and five, and no other pair moves at all.

Not verified: colour, since the reconstruction is text; the vertical position
of the block, which bottom anchoring moves by construction; and whether the
free-text cursor's background-filled cell survives layout, which a text frame
cannot show.

* fix(cli): keep a keystroke burst intact in OpenTUI's auth inputs

The shared line-input helper behind the endpoint and API-key steps built each
next value from the value the registering render had captured. Keystrokes read
out of one pty buffer can be delivered inside a single React batch, where no
render separates them, so every character in the burst appended to the same
stale snapshot and the input ended up holding only the last one. A pasted
string was safe because a bracketed paste arrives as one event carrying the
whole text, and ordinary typing at human speed was safe because each keystroke
flushed a render first, which is why the existing tests, one act per character,
never saw it.

The helper now keeps a mirror of the value that is written synchronously on
every change and re-synced on render, so each event appends to what the
previous one produced while a value set from anywhere else is still picked up.
Both steps reach it through plain state setters that store exactly what they
are given, so the mirror converges with the parent on the next render and the
fix stays inside the helper, leaving ink's own wizard untouched.

Pinned by dispatching a whole burst inside one act and asserting the input
holds all of it and carries it into the next step. Taking the mirror out fails
that test alone, with a twelve-character key rendering as its final character.

This is correctness by construction: no truncation was observed on a real
machine, and no acceptance scenario drives the authentication wizard, so the
fix has unit coverage only.

* fix(cli): draw ink's inline tool arguments row in OpenTUI

With `ui.showToolCallArgs` on, ink writes a call's raw arguments on a dim row
under the card header, capped to two wrapped rows with the remainder collapsed
into `… +N chars (ctrl+o)` and printed in full once ctrl+O puts the session in
its detail state. The setting had no reader here, so the row existed nowhere
and a call's payload stayed invisible outside its one-line summary.

The policy is not reimplemented. Serialisation, the deduplication against a
description that already is the payload, the character budget scaled by the
header's own inner width, the surrogate-safe walk and the prompt-injection
sanitisation all come from the helper ink uses, which is split so that both
renderers read one source of truth for the row.

Investigation corrected the premise before a line was written: the live path
already carried the arguments, on the event that opens the card, and that is
the same value ink's setting reads. Only two carriers were missing — the
steering card raised by an `@`-mentioned file, and a resumed session's
transcript — and the row still drew nowhere because nothing read the field off
the item. A first attempt added a fourth source in the scheduler loop and was
reverted once the tests showed it emitting the same row twice per call; what it
exposed was that the pre-existing carrier had no test at all, so a fold that
dropped it would have passed. That carrier is pinned now, along with the two
that were filled in.

The arrow that marks an awaiting call moved onto ink's gate with it. It was
drawn on every pending card, while ink draws it on the first one — this
renderer shows only that call's dialog, so every other arrow marked a call the
user could not act on.

Frame-verified against ink on a real machine while the call is pending, after
it settles, and in the untruncated state, at 100 columns. Two divergences are
recorded rather than closed: the row costs this renderer one more physical row,
which a control arm raising the same header with the row switched off reproduces
unchanged, so it belongs to the wrap rule and not to this row; and ink's
per-group height reservation has no counterpart where every card is handed the
same per-item ceiling.

* docs: correct the row-budget claim the viewport fix overturned

Drawing the confirmation inline was recorded as making the row budget that
reserved space for the removed chrome inert at the heights the harness uses.
It is not inert, and the harness never reaches the height where it binds: the
reserve was raised upstream after a long confirmation on an 80-row terminal
pushed the payload's tail and the outcome list past the bottom edge, and this
branch was rebased onto that fix. Both language versions now record the
re-derivation and the two arms that bound the value — the scenario is green at
the shipped reserve and times out waiting for the tail at zero, but stays green
four rows lower, so the arithmetic is what pins it.

* docs: retire the two card gaps this change closed

The follow-up list still recorded the missing inline arguments row and the
pending indicator on every card, both of which the last commit on this branch
drew. Lead the item with the gap that stays open — a settled card keeps the
position it was created at — and say what closed the other two, so a reader
does not implement a fix that has landed.

* fix(cli): keep shell output within ink's history retention

ink compacts a shell card's display through the shared history retention
policy while handing the model the verbatim output; the OpenTUI shell path
skipped the compaction on both the streamed snapshots and the final result,
so a long-running command could pin its whole output in the transcript.

* fix(cli): keep OpenTUI's conversation inside the terminal

The app column was laid out at the height of its content, so a conversation
longer than the terminal pushed the composer, the waiting row and the footer
past the last row, where nothing repaints them — a second turn left the
reconstructed frame byte-identical until the checkpoint timed out, and a dialog
taller than what was left lost its closing border the same way. ink never sees
this because its permanent output goes into the terminal's own scrollback; the
library's split-footer equivalent bounds the render tree to the footer band and
feeds the region above from captured stdout, so it cannot carry transcript items
authored in the tree.

Everything that flows — banner, transcript, the two notice rows — now lives in a
scroll region bounded by the terminal, pinned to its last row until the user
scrolls away from the bottom, while the rows below it are locked against
shrinking. Without that lock the layout spreads the region's content height over
the column and squeezes the composer's three border rows into one row painted
three times. The overflow arm then matches ink row for row, differing only by
the scrollbar indicator, and the wheel was measured on that arm: twenty notches
move the region back twenty rows with the chrome unmoved, sixty the other way let
the anchor take the tail again. Two divergences this document had recorded as
deliberate — a persistent banner, and a dialog that did not reflow the
conversation — close as a side effect.

* docs: record the shell-output compaction this branch already ships

The follow-up list still described the shell card as keeping its whole
output on screen, although the compaction landed on this branch, and it
claimed ink discards shell progress — ink renders the streamed output as
a pending item, which is what the compacted snapshot beside it is for.
Both languages now carry the decision instead, with the two unit arms
that pin it and the mutation showing they fail without the compaction.

* docs: attribute the startup update-check notice to the runtime

A control arm — ink under the runtime the OpenTUI leg uses — reproduces the
notice on ink, so its absence from ink's frames is not a renderer choice. The
explanation this document recorded instead (a subscription race, with ink
showing a later hard failure) is retracted: no arm showed a hard failure.

* fix(cli): freeze the waiting row's spinner while a confirmation is open

ink's responding spinner animates only while a turn is responding and draws one
static frame while a call is parked on a confirmation, so its waiting row emits
no bytes at all until the user answers. This renderer's spinner owned an
unconditional interval, so the row kept repainting: measured on a real machine at
about twelve bytes a second against ink's zero, holding a different frame at
every one-second sample. The acceptance harness decides a leg has settled by
watching its output go quiet, so every parked leg of a confirmation scenario also
burned the full sixty-second idle timeout.

Port the gate, and move the frame it freezes on out of ink's literal into the
spinner constants both renderers already read from one place.

* fix(cli): cancel a pending tab swap when a second answer lands inside the pause

Answering a question schedules the swap after ink's 150ms pause. A second
answer inside that window overwrote the timer handle without clearing it, so
both timers fired and the question between them was skipped without ever being
drawn — the same failure the ported dialog exists to remove, reached by another
route. The pause was carried over from ink, which keeps no handle to its timer
and so cannot cancel it either.

Also restates the sweep's remaining residuals against the matrix re-run on the
frozen waiting row: the parked spinner frame and the startup update notice are
no longer open items, leaving the long-path wrap break and vertical anchoring.

* fix(cli): drop the footer while a gated server holds the dialog slot

ink's layout swaps the whole Composer — footer included — for the dialog mount
whenever it counts any dialog visible, and the startup server approval is one of
them. This renderer gave the approval the Composer's slot while leaving the
footer on a gate of its own that knew about the shell confirmation, the action
modal, the tool confirmation and the completion list, but not about the new
occupant — so two rows ink does not draw stayed painted under the box. The line
by line read of that frame is what turned it up; the frame now differs only by
the two residuals already recorded for it.

* fix(cli): hold ink's pending glyph on a call queued behind another approval

A turn that returns two calls needing approval parks the first in the
scheduler's 'scheduled' status until the second's answer arrives. ink reads
that status and keeps its pending glyph on the card; this renderer went
straight to the executing one, drawing work in progress on a call waiting for
a person. The status was already on the batch update this renderer consumes, so
this reads it there rather than touching the scheduler, and emits it only when
it changes.

Found by a new acceptance scenario that captures the screen between the two
approvals, and confirmed on the machine with a single-variable comparison: the
row pairs off and the checkpoint drops from four divergent rows to three.

* docs: record the inline-confirmation row reserves as named debt

A review pass noted that the two reserves sizing the conversation around an
expanded confirmation would rot silently if that geometry ever changed: they
are hand-counted from a row inventory, the live scenario separates the shipped
value from zero but not from four rows smaller, and the unit tests assert the
arithmetic the constants feed rather than the screen. Both languages of the
design doc now say so where the follow-ups are kept.

* fix(cli): list mid-turn queued prompts above the composer

A prompt submitted while a turn was running was counted here but never shown:
its length reached the footer badge and the composer could pop it back for
editing, but the texts themselves were readable only by draining the queue,
which empties it. ink lists them above the composer instead — three at a time,
each collapsed to one line, an overflow row and a fading hint — so this ports
that component row for row.

The queue stays in a ref, because a turn drains it and puts it back within one
tick and a ref is what that needs; the five sites that move it now copy it into
state besides, which is also why a cleared screen sheds the rows with it. No
frame can show this one: both renderers steer a plain-Enter submission at the
next sampling boundary, so a queue that outlives the turn needs the deferral ink
puts behind Ctrl+Q, a key this renderer does not bind. Coverage is therefore
unit-level, and the design doc records that the ported hint now prints that
unbound key on screen.

* docs: correct the mutation counts recorded for the queued prompt rows

The recorded coverage claimed nine mutations, one per component behaviour and
per mirror site, each failing its own test alone. Re-running the set says
otherwise: eleven mutations, and the mirror sites do not map one to one because
a list never given its first entry, or never emptied, is asserted turns later.

* docs: state the queued row hint's cut-off and its assertion layers exactly

The coverage sentence read as if the hint survived its fourth fill, and listed
the transcript reset twice: once among the five sites that mirror the queue and
again as an extra assertion layer.

* fix(cli): record the model dialog's outcome like ink does

The row a `/model` dialog leaves behind reached the transcript but not the
session log, so resuming a session dropped the model a pick settled on or the
one an escape kept, where ink replays it. The dispatcher cannot carry it: its
result phase closes while the dialog is still open, with an empty output list,
and ink writes that same empty pair. Ink then pairs each of its three outcome
sites with a second result-phase record naming the command and carrying that
one row, which is what this commit adds here.

The pairing goes over one object, so the row shown and the row recorded are the
same value built once and cannot drift apart. Two silences are deliberate: a
pick that fails to apply records nothing, because ink keeps the dialog open with
the error and a recorded row would replay a switch that never happened; and the
dialog adds no invocation-phase record, because the bare command's own
invocation is already written, hidden, by the dispatcher.

Three existing cases in the dialog suite now assert the recorder alongside the
row and a new one covers the failed pick. Five mutations — no record, wrong
phase, wrong command, empty payload, a failure that reports anyway — each fail
at least one of them. On a real machine the slash-dialog scenario was run on
both legs: the two session logs now hold nine `slash_command` records in the
same order with the same flags, the fifth being the dialog's own result carrying
`Kept model as fake-model` on both sides. What is not shown on screen is the
replay itself; no scenario resumed a session, so that step rests on source
reading, and the design doc records the boundary.

The sweep also surfaced two parity classes left open rather than widened into
here: most dialogs answer through a notice slot that the next submit clears, so
their outcomes never reach history or the log at all, and an auxiliary model
pick is a success row in ink where every model outcome here is an info row. Both
are documented as follow-ups.

* fix(cli): let OpenTUI dialog fields move the caret like ink's

Every text field in these dialogs kept its value in the dialog's own state and
only ever appended to it, so the keyboard could add a character and drop the
last one: the arrows, Home and End did nothing, and a mistyped character in the
middle of a value could only be repaired by erasing everything after it. ink
hands the same fields to one text input component whose editing lives in a
buffer that measures the caret in code points, so those keys move it there.

The buffer is not a rewrite of what ink's ought to do. It is a one-line slice of
ink's own operations, and its differential suite holds no hand-written
expectations: each fixture drives the same keystrokes through ink's reducer and
this model and compares the text and the caret offset after every step — across
a paste that leaves a line break behind, across code points ink weighs as one
cell or two, and across both walls when the caret is already at one. Word
segmentation is reused as ink's, with two helpers that were module-private now
exported so what ctrl+W erases is what ink erases; the key order is ink's too,
taking only the keys a one-line field can receive and handing every other key
back to the dialog, which is what ink needs because its dialog stops handling the
arrows once a field owns the row. Word jumps, delete-word-right, kill-line and
undo/redo are recorded as not ported, and ink binds all four. Two absences are
forced: ctrl+D belongs to the app's global exit binding, and a field whose value
is replaced wholesale pulls its caret back inside the string rather than leaving
it past the end.

Three rendering differences are kept and documented: ink windows the field at a
fixed column count and shows only the caret's line, so a multi-line paste hides
what it cannot see, while these rows render the whole value; ink blinks the
cursor cell every 530 ms, where a steady cell spares the dialog a repaint timer —
measurable, not just source, since in a scenario parked on one of these rows
ink's leg wrote 270 KB per minute sitting there and burned four of seven idle
waits in full, taking 251 s against this renderer's 14; and the cell carries the
theme accent, as the composer's cursor does, where ink paints gray read from the
terminal background.

Mount semantics differ per field because ink's do. The question dialog mounts the
row's input only while its option is selected, at the end of the stored value, so
this port treats the row becoming selected again as a fresh mount and drops a
caret left mid-value; the wizard's custom-model field is not unmounted when the
list below takes focus, so Tab returns it to where it was left.

One field's text is not the model's either. The context-window setter keeps
digits only and this port renders what it is handed, so a character that setter
rejects — a letter, or the Space that step binds — moves the caret and never
appears in the row, where ink's buffer is the source of truth and shows what its
own flow discarded. Both land the caret in the same column, and that display gap
predates this change, so it is recorded as follow-up work rather than copied.

Coverage is twenty-two new cases across three suites — thirteen the model itself,
against ink, the rest using its fields — plus seven mutations, each failing the
tests that own the behaviour: the left arrow stops moving, the context-row input
branch, both end-of-line bindings, forward delete, a modified Delete that erases
a character instead of passing through, ctrl+W, and a row that stops
re-mounting. On a real machine a new scenario answers one question from the free
text row, and only one, so the tab clamping and the double trigger recorded
earlier cannot be the source of the frame: type six characters, step the caret
back two, insert one. Both legs show `> abcdXef` at the same column of the same
row and both record `abcdXef` as the answer. The styled capture pins that down —
in the frame both legs caught together, ink's cursor cell and this renderer's sit
on the same character in the same column, differing in two colours only; in the
two frames before it ink's cell is absent at all, which is its blink interval and
not a missing cursor. No scenario reaches the auth wizard, as before: its four
fields' editing rests on the unit suites alone. One test-runtime note is recorded
with it, because it cost a debugging round: the DOM runtime used by the field
tests keeps stale renders of a re-rendered row mounted beside the live one, so the
probe reads the last cursor cell — the same JSX shape driven through five state
changes in the real renderer holds one row, so this is scaffolding, not the dialog.

The full ink/OpenTUI matrix was rerun on this tree: twenty-six scenarios, no
scenario errors, twenty-two of seventy-seven checkpoints byte-identical, and the
frames of the three earlier dialog scenarios unchanged against the previous run.

* docs: correct the cursor-cell frames recorded for the dialog caret

The coverage paragraph claimed ink's cursor cell was absent in the two frames
before the one where both legs show it, and attributed that to the blink
interval. Reading the captures says otherwise. The cell is on screen at two
checkpoints, not one — over the same character in the same column on both legs
each time — and in the frame between them the caret rests past the last
character, so the cell each leg would paint is a trailing blank the capture
drops and neither side shows one. The frame where the two legs really do differ
is the first, where the field is empty and this renderer paints the cursor over
the placeholder's first character while ink shows the placeholder whole; that one
is the blink phase, and it is the only absence the paragraph should lean on.

The same re-read puts this renderer's leg of that scenario at 13 s rather than
the 14 recorded, against ink's 251.

The commit message of the change these notes were written for carries the earlier
wording; it is left as pushed, and this is the correction to the record.

* fix(cli): point the awaiting arrow at the call the queue can answer

The marker that says "this card is the one on screen asking for you" was
derived from the transcript: the first row that is a pending, unfinished tool
card. That is not the same call as the one whose confirmation is showing. A
PreToolUse ask hook re-arms a call that was already approved by putting it at
the back of the waiting queue, while its own card goes back to pending where it
already sits in the transcript — so the two orders disagree, and the arrow
landed on a card with nothing behind it to answer while the card that was
actually waiting showed none.

The queue knows which call is on screen, so the view is told its identifier and
draws the marker only on a row that both carries it and is still an unanswered
pending card. Keeping the second condition is what preserves the one-arrow rule:
a card the queue names but the transcript has already settled shows nothing,
exactly as before. Where there is no queue at all, no row is marked.

* fix(cli): keep a keystroke burst intact across the dialog fields and rows

The first review round found, for the shared line-input helper, the same defect
that had already been closed for the composer: a dialog read the value out of
its own state, so a keystroke handled after another one in the same batch
appended to what the last render had drawn and the earlier character was lost.
That class was not confined to one helper. Every dialog row that answers from
the position it last drew has it, and a terminal delivers three ordinary things
as one burst: a held arrow repeats about every thirty milliseconds, a bracketed
paste arrives with the Enter its terminal appends, and a fast typist's keys land
together.

The question dialog now keeps its tab, its cursor row, its checked options and
each free-text entry in a mirror written as the key is handled, and derives what
a key acts on from the burst's live position rather than from the render that
installed the handler. So a held arrow walks every row it repeats through and a
Space ticks the one it reached, and an Enter that follows a typed answer within
one read commits what was typed instead of refusing the empty value it was
showing when the read began. The same fix in the authentication wizard carries
the endpoint typed in one batch with its Enter all the way to the saved plan,
where it used to be discarded and replaced by the protocol default.

Two consequences of making a mid-read submit work are closed with it. A field
now stops taking keys once the Enter it handled has moved the step on, so the
rest of that read cannot write into the step the burst already left behind; a
refused Enter, which leaves the step mounted, keeps taking them. And a manual
tab move calls off the swap the answer scheduled a beat earlier, which otherwise
fired one tab further on and skipped a question nobody had answered.

A caret the value's owner refused now falls back to the last offset the accepted
text agrees with, so a character a field strips leaves no trace at all:
previously it stepped the caret right, and the next erasure deleted a character
the user never typed. Along with it, a field that has lost the focus prints the
character the caret is on rather than dropping it — the highlight is what says
which row owns the cursor, and omitting the character printed a value one
shorter than the one held.

None of this reaches a machine: the acceptance harness writes one character per
write and never pastes into a dialog, so every case here is a unit test, and
each of the behaviours above is pinned by a mutation that fails exactly the test
owning it.

* docs: record the keystroke-burst decisions and correct what the sweep claimed

Five entries are added for this round: why a burst of keystrokes is handled by
the render it started in and what the dialogs now mirror against that, why a
manual tab move calls off a scheduled swap where the reference implementation
lets both fire, why a caret the owner refused falls back and a field out of
focus still prints its character, why the marker for an awaiting call is named
by the queue rather than by transcript order, and what makes a field stop taking
keys after its own read has submitted it.

The coverage notes are corrected where they overclaimed. The reference
implementation's own wizard suite was recorded as failing a fixed set of tests
here; six runs at this head say the count moves with the machine, and a
one-variable control says the shared provider-setup hook edited this round is
not what fails them. Two gaps that this round leaves open are written down as
well: the stop that settles a field does not settle a step, and it stops keys
but not a paste that shares its read.

* fix(cli): read the loading-phrase setting for the waiting row

ink's Composer drops the phrase, not the row, when
ui.accessibility.enableLoadingPhrases is off; this renderer ignored the
setting. The parked-row tests now read the mechanism too — that no timer is
left running, and that no cancel affordance is offered for a request that is
not in flight — rather than only the glyph the cell happens to show.

* fix(cli): sanitize a queued prompt before the waiting row shows it

A row listed the prompt raw while the same string goes through
sanitizeTerminalText once the queue is consumed, so an escape sequence typed
into the composer reached the terminal from a row that only displays text.

* refactor(cli): drop the @-mention card's unreachable arguments row

handleAtCommand builds every display it returns as a closed literal with no
arguments, so formatToolArgs never produced a string here and the row was
never drawn. The test that covered it passed on a fake that supplied an
argument object production cannot give, which is why the suite stayed green
over dead code.

* test(cli): stop handing React a null key in the dialog harnesses

The stub renderer forwarded whatever key the element carried, and an absent
one arrived as null, which React reports as a reserved prop on every element
the two dialog suites build.

* docs(cli): correct what two source comments claim

The line editor said the global exit binding takes ctrl+D before a field sees
it; the binding acts on the key without swallowing it, and the reducer hands
it back unhandled. The expanded-window comment had the two failure directions
of its reserve swapped, and cited a line number in another file.

* docs: record the pointer divergence and the pins review measured as loose

Decision 21 now names the two deliberate diverances separately — a defect ink
has that this port does not, and the pointer affordance this port lost when the
option rows were drawn by hand. Decision 21's residual list drops vertical
anchoring, which the retraction at the top of that section already disowns, and
Decision 22 stops treating a reconstruction artefact as a frame finding.
Decision 28 says which half of its mutation pair pinned the timer, Decision 30
scopes its queue rows to the steering lane and marks the mount pin as
containment rather than order, and Decision 32 corrects the ctrl+D claim. Four
follow-ups record the unported key families, the refused-keystroke divergence,
the exit handler's missing claim, and seven pins that survive a mutation.

* fix(cli): keep a click on the transcript out of the composer's focus

The transcript scroll region was focusable by class default, and the
renderer focuses the first focusable ancestor under a left mouse-down, so
one click anywhere in the conversation blurred the composer's editor for
the rest of the session. Printable keys kept arriving through the
composer's own global handler, which hid it: caret keys and pastes went
where nothing was listening, because a renderable attaches those handlers
only while focused.

* fix(cli): stop the bare End key at its own line in dialog fields

ink has two distinct "go right" keys and this renderer collapsed them into
one. Ctrl+E moves through the reducer and lands past the last code point of
the whole value, so a multi-line paste ends after its final line. A bare End
falls through to ink's text buffer instead, whose `end` move stops at the end
of the visual line the caret sits on — so typing after End on the first row of
a two-row value inserts there rather than appending at the bottom. Dispatch
the two keys to their own moves and differential-test the pair against ink's
reducer, including a bare End then a keystroke on a line break.

Separately, the queued-prompt rows and their hint counter mount inside the
composer's branch, which this renderer hands to a parked tool confirmation,
so those rows leave the screen for a state where ink keeps them. That is
recorded as a divergence rather than fixed: hoisting them above the branch
would place them over the waiting row where ink draws them under the spinner.

* fix(cli): fit the question dialog's chip row to the room it has

The header cap copied ink's overhead terms along with the width they are
subtracted from, but this row is not drawn in ink's box. It spends two columns
of margin here, and the padding it spends is already one of those overheads, so
the row was billed for eight columns it does not spend and a header was
ellipsized where the row still had room. Re-deriving the base from this row's
box was then checked against a laid-out frame rather than the props it came
from: headers print whole here where ink reaches for the ellipsis at the same
width, and that window is recorded in the design doc.

* fix(cli): erase a word for the byte a legacy terminal sends for it

ink binds ctrl+W, and this port erases a word for that and for a backspace
carrying a modifier, which is what a terminal that reports modifiers sends. A
terminal that reports none sends the bare 0x1f byte instead, and that byte
reached a dialog field and did nothing: not inserted, because a control
character is not printable, and not handled, because only the composer had been
taught it. Both field paths now ask the composer's own predicate, so the one
spelling they had not shared is shared.

* docs: correct what a resumed session brings back for a slash command

The record a model dialog leaves behind was claimed to be missing where ink
keeps it on screen. ink keeps a record of each of its outcome sites too, and
what this renderer loses on a resume is wider than that one dialog: its
transcript adapter replays a slash command's invocation phase only, so no slash
result comes back at all. That gap now reads as the app-wide one it is, and is
carried into the follow-ups list alongside the chip row's clipping window, which
was recorded the same way.

* fix(cli): keep a pasted newline inside the row the caret sits on

A bracketed paste is the only way a newline reaches a dialog field, and
the rows that draw these fields rendered the whole value. This port's
cursor is a cell set beside the text it marks, so one break grew the row
past the dialog's height budget and left the highlighted cell on another
line than the caret. The rows now draw the caret's line only, as ink's
single-line field does, while the value keeps the break so the answer
that reaches the model is the same text.

* fix(cli): hold a settled field closed and follow the tail its owner accepted

The latch a submit armed was a per-render binding, so the re-render the submit
itself scheduled cleared it and the next key of the same stdin read kept editing
a row the wizard had already left. It is a ref now, re-armed only where the
field's mirror is re-seeded, and it is checked inside the insert path so a
bracketed paste trailing the Enter is stopped the same way a key is.

The caret rule beside it capped the caret at the shared prefix of the proposed
and accepted values, which strands it on the first code point an owner dropped
out of the middle of a paste. Walking the two texts and charging the caret only
for the drops ahead of it keeps the caret following the accepted tail, and the
old cap remains the fallback for an owner that inserts or substitutes.

* fix(cli): mirror the question dialog's answers and lock a settled row

Two reads of an answer still came from rendered state, so a single stdin read
that typed into a multi-select's free-text row and then submitted left that entry
out, and one that answered a question and then submitted from the review tab left
that answer out. Both now read a mirror written synchronously, with state kept as
the fallback for the reads that run during render.

The row a pending tab swap settled is still drawn and still owns the keys, so the
rest of one read answered the same question again and quietly replaced the answer
already recorded — a digit on the option branch, or a Space that a multi-select
rebuilds its answer from at submit. Answers are locked while that swap is armed.
Navigation is not: a manual arrow still calls the swap off and takes the cursor
with it.

* fix(cli): pause the loading row's timer while a call is parked

The row already freezes its spinner and drops its suffix while a tool call waits
on a confirmation, but its elapsed counter kept running on the active flag alone.
Wiring the parked state out of that flag is the obvious fix and the wrong one:
the shared timer zeroes what it has accumulated on a false-to-true edge, so a
turn that had been running for half a minute reported itself as four seconds old
once the user answered. It is handed the timer's separate paused flag instead,
which holds the accumulated time and carries on from it.

* docs(design): record the answer lock and the parked timer, correct the counts

Adds the two behaviours this round landed to the parity sweep design in both
languages, drops a follow-up entry the mirrors closed, and replaces coverage
totals that had gone stale with counts a reader can re-measure against the
suites.

* docs(design): correct the ctrl+C actor set and the unported key families

The follow-up bullet claimed three handlers act on ctrl+C at once. The shell
mounts five exclusive branches, so only the on-screen one joins the app-wide
exit handler; the rewind overlay that binds the key has no importer. The
key-family bullet also said every operation the four families need already
exists, which is not true of undo/redo — it needs a history the line model
does not keep.

* test(cli): pin the wiring and placement the review measured as free

Every one of the six pins the last review round measured as not holding was
an assertion that read what was rendered, so a change that rendered the same
thing survived it. Each now asserts the placement, the wiring or the state
instead, and each was re-measured by removing the behaviour it names.

The round's remaining review suggestions are closed the same way: a digit on
a multi-select tab moves the cursor rather than ticking the option it names,
the burst that ends on another tab is checked for what it stored as well as
what it drew, the loading-phrase setting is pinned at both of its mounts, the
queued-call id and the arguments setting are read off the tree the entry point
renders, ctrl+E is shown crossing a line break, and the finished-call term of
the arrow gate has a witness of its own.

The design document's coverage counts and its pin register follow, in both
language versions.

* test(cli): witness the ctrl+E routing the review measured as free

Every fixture that pressed ctrl+E held a value with no line break, where the
buffer-end jump and the line-end jump land in the same column, so routing the
key to the line-scoped move survived. Press both keys through the routing on a
value that holds a break with the caret off its last line.

* fix(cli): bound the ask-user answer row and re-arm a wizard field after a failed submit

The question dialog's free-text answer is the one row a paste can make
arbitrarily long, and the confirmation it lives in has no body window of its
own, so a single long paste grew the dialog past the terminal height and pushed
the options still to be picked off screen. The row now draws inside the same
fixed window ink's TextInput gives that field, caret cell included, while the
submitted answer keeps every character. The collapsed echo of the same value is
bounded the same way.

A bracketed paste is one event with no keypress per character, so it was read
against the render that drew the row rather than the cursor the keys of the same
stdin read had already moved, and it did not ask whether the answer it would
widen had been recorded. Both are now asked of the live position.

Every text field of the provider wizard latches itself shut on the Enter that
submits it, and only a mount-key change clears that latch. On the last step the
submit is async, so a rejected install — or one that saved service models
without a conversation model — left the very same step on screen with every key
dead, and backing out of the wizard was the only way left. A retry counter now
hands the field back on both paths.

* fix(cli): settle the answer row on the verdict that records it

A submit the answer lock rejects used to settle the field before the call
that could refuse it, against the contract the shared line model states for
its own latch. The letters trailing that Enter in the same read then reached
a row that had closed, so the answer the user came back to give was the
shorter one. The call now reports whether the answer was recorded and the
field settles on that verdict.

The tab swap cancelled on the answer path goes with it. A lock added in an
earlier round drops a second answer inside the pause before it reaches that
cancel, and a live timer always belongs to the tab the cursor is still on, so
putting the call back fails no test — which is the measurement that showed it
unreachable.

The design doc is corrected in both languages for this round's findings, with
the mutation counts measured rather than restated.

* refactor(cli): collapse the answer lock to the armed timer alone

The lock that drops a second answer inside the dialog's 150 ms pause also
asked which tab the pending swap belonged to, and that clause could never be
false while a timer was armed: the only moves of the cursor's tab are the
swap's own callback, which nulls the timer first, and the two arrows, which
cancel the swap first. The ref modelling it goes with the dead cancel it
accompanied, and the whole suite is green with the clause removed — which is
the measurement that showed it unobservable.

The design doc records the collapse in both languages, as this round's tenth
mutation.

* docs: record the machine leg of the round-three fixes

The matrix was re-run at this head, so the placeholder that stood in for
its result is replaced with the measurement: fifty-four runs over
twenty-seven scenarios with no error, the checkpoint split and the
divergent-row counts, and how many captures are unchanged against the
previous head. The same pass states that none of the round's five items
moves a frame and why, so the unit suites are named as what carries them.

Two counts in the coverage boundary had gone stale against the matrix as
it runs — one scenario and one checkpoint were missing from both — and
the scenario enumeration in the method section was missing the chip-row
arm. Both languages are corrected together.

* docs: record the matrix re-run after merging main

The merge moved one thing on a frame — the version the banner prints — so
the counts Decision 39 quotes are re-measured rather than carried over, and
the byte-identity comparison states the normalisation it needed.

* fix(cli): scope the answer row's re-arm, lock, width and caret cell

A retry counter bumped by an asynchronous verdict re-seeded whichever
field happened to be mounted when the verdict landed, so a rejection
arriving after the user had backed out discarded a caret parked in a
field that never submitted. Only the step that fired the install may
bump it now.

The free-text row's editing branch was the one mutation of a
multi-select answer that never asked whether a pause was still holding
it, so letters typed inside that pause widened an answer Enter had
already recorded. The branch asks now, and only on a multi-select, so a
single-select field whose submit the pause rejected stays editable.

The caret cell was the one span of either dialog's field drawn without
sanitising, while both spans beside it went through it, so a bidi
override a paste parked in a value was emitted raw from the cell the
user is looking at and rewrote the direction of the row. Both fields
sanitise all three spans; the submitted value keeps every code point.

The row's width budget charged the confirmation box's margin and not
its padding, so on a terminal of sixty columns or narrower the last two
cells it drew — the caret cell among them — fell outside the box that
contains them.

The design document scopes Decision 39's premise to the payload the
bound actually covers and records the four fixes, their mutations and
the re-run machine leg as Decision 40.

* docs: attribute the answer lock to the branches Decision 37 put it on

Decision 40 said Decision 37 had stopped the free-text row's insert
branch on a locked answer. It had not: the lock went on the digit branch
and a multi-select's Space, Decision 39 extended it to the paste path,
and the editing branch was left to the field's own latch, which arms only
on an Enter that moved the dialog. An Enter on the option row arms the
pause without arming that latch, which is the gap this round closed.

Also re-wrap the answer-row paragraph Decision 39's scoped premise left
one line past the document's width.

ChiGaoandgary.gq e4a6ccd449 fix(cli): scope the ACP permission queue to the session (#11802)
* fix(cli): scope the ACP permission queue to the session

The permission queue was keyed on the AgentSideConnection, but a daemon
child owns exactly one connection that every session on it multiplexes
onto. One unanswered question in an idle session therefore head-of-line
blocks every sibling session, and with the mediator timeout disabled by
default the wait is both unbounded and invisible: the blocked request is
never published, so hosts report no pending interaction at all.

Keep the queue -- a single session does have concurrent permission
producers -- and narrow its unit of serialization to the session, which
is what the bridge already models with its per-session promptQueue.

* fix(cli): Remove the unused unqueued Session.requestPermission

SubAgentTracker receives #requestPermissionQueued from the session that
constructs it, and its own default goes straight to the connection, so no
caller ever reached this method. Its docstring named a caller that uses the
queued path, which left an unqueued route onto the shared connection sitting
beside the queue that is meant to own the boundary.

* test(cli): Pin the abandoned-while-queued permission request to the floor

A request whose caller aborts while it is still queued behind its session's
head is dropped instead of published, because an RPC that reaches the client
after its caller is gone becomes a prompt nobody can answer or cancel. That
short-circuit predates the queue-scoping change and no test covered it, so a
mutation that removes it leaves the suite green.

Add the missing case: hold one request unanswered, queue a second, abort the
queued one, then release the head and assert the client was contacted exactly
once. A third request from the same session then proves dropping the abandoned
one did not wedge the queue.

* test(cli): Pin each session's permission settlement and share the approval fixture

The cross-session test asserted only where the request went. It now also
asserts that each session settles its own approval against its own run
registry, so a queue that mis-scoped the receive half as well as the send
half cannot pass. Verified discriminating: forcing the run id to a constant
fails the test.

Four of these tests had each copied the same approval fixture verbatim; one
of them was added here. Hoisted into a single helper, assertions unmoved.

ChiGao 7156037d6a fix(cli): close the OpenTUI renderer's parity gaps against ink (#11630)
* fix(cli): give the OpenTUI confirmation dialog ink's per-type approvals

The OpenTUI dialog offered one generic four-row list for every tool
confirmation. That cost three things users rely on when deciding whether
to grant access.

The always-allow rows did not say what they were allowing, so approving
"Always allow in this project" gave no hint that the grant covers every
`touch` invocation rather than the one command on screen. They were also
offered in an untrusted folder, where a durable permission rule for a
workspace the user has not trusted is not a decision the dialog should
put in front of them.

Plan and edit confirmations got the wrong choices outright: a plan was
never offered the chance to restore the approval mode it replaced, and an
edit was offered the project/user-scoped persistence outcomes instead of
the session-wide allow-always that an edit actually supports.

Approval rows are numbered again, and a digit key picks one, matching the
inline prompt. Each type now also shows its own question line, so an
execution approval names the command root being permitted.

* fix(cli): warm the shell AST parser before the OpenTUI renderer boots

The OpenTUI renderer constructor installs a bare `globalThis.window` to
hang its requestAnimationFrame shim on. web-tree-sitter's UMD wrapper
probes `window.document.currentScript` when it is first evaluated, so
the first dynamic import after that point throws, and the parser latches
that failure permanently for the rest of the process.

Every OpenTUI session therefore silently lost AST-based shell analysis:
permission rules came back empty, so always-allow confirmations lost
their scope and persisted nothing, and read-only detection and
command-safety classification dropped to their conservative fallbacks.

Initialise the parser before the renderer exists, while `window` is
still undefined. Adds a one-line re-export from the core package index;
web-tree-sitter stays dynamically imported, so the deferred-runtime
invariant is unchanged.

* fix(cli): give the OpenTUI footer ink's status rows and token estimate

The status row was truncated to a single line, so a narrow terminal dropped
the model segment that ink wraps onto a second row. The hint row now carries
the approval-mode name the composer stopped drawing, since ink uses that text
as an aria-label rather than a visible row and this renderer has no aria
surface. The hint row is still truncated, so it cannot grow the footer
mid-turn.

The loading indicator advertised an output-token estimate it never received:
the character counter and the receiving flag were declared as props but no
caller set them, so the estimate stayed pinned at zero and the direction arrow
always pointed down. Both now come from the live turn, counting model text,
thoughts and tool-call arguments the way ink does, and flipping back to the
waiting phase when tool results go to the model.

The footer also hid while a completion list was open only in ink; here it
drew under the dropdown and pushed the composer around.

* fix(cli): match ink's completion dropdown and bind Shift+Tab in OpenTUI

The slash dropdown never populated a command's source badge, so skill, plugin
and MCP rows lost the marker ink draws and the shared label column was sized
without counting it. Descriptions were emitted verbatim, so a multi-line
command blurb kept its frontmatter line breaks and an over-wide one spilled
onto a second row, doubling the height of the popup. The row budget also
ignored that the dropdown nests its own side margins inside the composer's,
which left two columns too many for the description and wrapped its tail.

A label and its argument hint were concatenated into one run, so a hint too
long for the column word-wrapped the whole string and grew the row to three
lines where ink produces two. They are now laid out as separate children and
broken at the column edge, which puts the continuation at the hint's own
offset exactly as ink does.

Shift+Tab was unbound, so the footer advertised a cycle shortcut that did
nothing and the mode could only be changed through the dialog. The shell now
holds the mode the way ink's indicator does: it cycles on the keystroke,
adopts the dialog's choice into the same state, reports a refused change
instead of repainting a mode it does not hold, and explains an entry into auto
mode — including at startup, where no keystroke ever runs. Windows accepts a
bare Tab because some terminals there cannot distinguish the two, and the
completion consumers both claim the key first, so a Tab spent accepting a
suggestion never reaches the cycle.

The cycle order now comes from the shared list of modes rather than a copy of
the enum's declaration order, so it cannot drift from the one ink walks.

* fix(cli): keep the OpenTUI auto-mode notice from reprinting on a re-pick

Both of ink's routes into auto mode gate the entry notices on the session not
already holding it. The rotation could never violate that, so the guard looked
redundant here and was left out — but the approval-mode dialog opens with the
current mode already selected, so a bare Enter re-picks it. The first-time
message survives that because it is acknowledged in settings; the notice listing
the allow rules auto mode stripped does not, and would reprint on every re-pick.

The gate now sits where both routes meet, and the comment that claimed ink's
slash command had no such gate is corrected: it does.

* fix(cli): give OpenTUI @-mention rows ink's full-width label column

The dropdown sized its label column the same way whatever was being completed.
That is right for slash commands, where every row shares one half-width command
column so the descriptions line up, but a file list is not a command list: ink
only shares a column there when a row carries a description to line up against,
and lets a plain path take the whole row. Clamping it to half the width instead
wrapped any path longer than that onto a second row, mid-word, so one entry
occupied two lines and pushed the rest of the list down.

The column now follows the mode being completed, and the cell keeps the shared
width only where a description has to line up against it. The minimum readable
description width that caps the shared column moves next to the other constants
the two renderers have to agree on, rather than being copied out of one of them.

* refactor(cli): drop the OpenTUI dropdown's unreachable described-row column

The label column gained a branch for rows that carry a description, mirroring
the other renderer. That branch cannot fire here: this renderer's `@` completion
only ever asks the file index, and its results carry no description, so the only
rows that reach the dropdown with one are slash-command rows — which already take
the shared half-width column. The column is therefore either that column or none,
and the minimum readable description width that capped the dead branch goes back
to being local to the renderer that uses it.

* fix(cli): match ink's popup geometry and its help and model dialogs

Every popup this shell renders spanned the terminal edge to edge, while ink
wraps its popups in a two-column margin and caps their width, so a border ran
from column 2 to column 97 and stopped there. The wrapper now supplies both,
which is what makes a dialog read as a dialog rather than a full-screen mode.
The confirmations stay outside it: their body measures the terminal width to
estimate how its text wraps, so narrowing the box without also narrowing that
measurement would corrupt the estimate.

The help dialog opened on its command list rather than its overview, and its
tab keys did not match the ones the footer advertises. Both now follow ink:
the overview is the opening tab, Tab and Shift+Tab cycle it in the two
directions the hint promises, the arrow and page keys move the command window
and are inert on a tab that has none, and no other key closes or navigates.
Closing on a bare letter key meant a typo dismissed the dialog.

That command window was a fixed eighteen rows whatever the terminal height,
which is more than the body budget leaves once the tab's own introduction line,
its gap and the scroll hint are counted. The overflow was resolved by dropping
the gap under the introduction and clipping the hint away entirely, so the
scroll position the hint reports was simply absent. The window is now sized to
what the budget leaves after that chrome, and paging moves by the window that
is actually on screen. Below a 42-row terminal this shows a shorter list than
ink does, which is the smaller loss: ink keeps its eighteen rows and clips the
hint instead.

The model dialog drew its detail rule twenty characters wide against ink's
full-width one, and showed no line under a model's title. ink folds the runtime
and discontinued markers into the row description as well as the title, so a
runtime model with nothing of its own to say still gets an explanatory line;
the entries now carry that, and the rule is spelled out to the frame's inner
width because there is no single-sided border here to draw one with.

* fix(cli): align the OpenTUI transcript, footer and dialogs with ink

A frame-by-frame comparison of both renderers over 14 pty scenarios
turned up a set of divergences that were invisible in unit tests. This
groups them by topic.

Tool output is a snapshot, not an increment. Core hands the shell the
whole accumulated display on every progress event, so a running tool
card that appended painted the streamed text once per event. The event
field is renamed to say so, the card replaces instead of accumulates,
and the throttle that stops a redundant re-emit now compares lengths.
Shell mode loses its tail-deduplication tail and writes the same string
to the card and to the model history, so the two cannot disagree.

The transcript and the composer get ink's horizontal margins, which
makes the dropdown, the attachments and the body columns land where ink
puts them. The status rows gain the prefixes ink draws -- a warning row
had none at all -- and the error row collapses its hint onto the same
line instead of a second one, with the prefix pinned so a wrapped body
cannot shrink it away.

The footer's loading indicator moves to ink's indent, and an armed quit
warning now renders even while a dialog, a confirmation or a dropdown
has the rest of the footer hidden. Previously the gate that hid the
footer also hid the warning, so pressing Ctrl+C once with a dialog open
gave no feedback at all.

Shift+Tab cycles the approval mode from the top level, so it keeps
working while a dialog or a confirmation has the composer unmounted --
the on-screen hint advertises it in exactly those states. The Windows
fallback that also accepts a bare Tab is narrowed to bare Tab only,
since a terminal that can tell them apart would otherwise cycle twice.

The context-files announcement is latched with the predicate ink uses
and re-armed when the transcript resets, so a new session in the same
renderer announces its context files again.

The model dialog carries the three guards ink has. A successful pick no
longer also announces the model that survived, and neither a second
Escape nor a second Enter landing mid-apply can announce or start a
second switch.

Dialog selection markers use ink's chevron rather than a filled bullet,
and the auth dialog takes the shared icon glyphs.

Adds the bilingual design doc recording each decision, the coverage
boundary and the follow-ups.

* fix(cli): give OpenTUI transcript items ink's per-type top margin

ink leaves a blank row above most conversation items and decides it per
item type in its history renderer; this renderer printed every item
flush against the one before it, so a completed turn read as one
unbroken block where ink reads as separated rows.

The comparison harness had been folding the gap away: it reduces each
captured frame to its non-blank rows, so a capture could be reported
byte-identical while the two renderers disagreed on every vertical gap
between items. Measuring the transcript region alone, as a run-length
pattern of blank and content rows, isolates it and is unaffected by the
two renderers anchoring to opposite ends of the screen. After the fix
that pattern matches ink's group for group in every capture that
carries a conversation item.

Each item is now wrapped in a box carrying the margin resolved from its
kind. Two kinds have no ink counterpart -- a task card, because ink
renders a subagent as the tool that spawned it, and an image row,
because ink draws images inline inside the message that carries them --
and both take zero so they stay flush against the tool row beside them.
The margin sits on the wrapper while the per-item row cap applies to the
item's own content, so the two are additive and neither can clip the
other.

The design documents record the mapping in both languages, along with
two limits of the evidence: layout props are unobservable in the unit
test runtime, so this is verified by frames only, and the blank rows ink
shows around its banner come from how it batches permanent writes rather
than from a layout rule, so they are deliberately not reproduced.

* fix(cli): close four OpenTUI gaps against ink's approval, thought and tool-result paths

An approval-mode switch now confirms the calls it would not have parked.
ink pairs the switch with the release; the selection rule deciding which
calls qualify was already ported here but had no caller, so the renderer
had the rule and not the behaviour.

A committed thought names its duration the way ink does, and the key its
collapsed hint advertises is now bound at the entry, so it still lands
while a dialog or a confirmation owns the screen.

A tool result's structured payload is resolved in one place. Five of the
six paths that turn a result display into events flattened straight to
text, which put a todo list's raw JSON on screen, on resume and on
replay, while the card's own checkbox-list renderer sat unused.

* docs(cli): retract the OpenTUI OAuth gap and keep the MCP approval one

The follow-up list reported two of ink's authentication progress screens as
missing here, on the grounds that a login could not be completed without
them. Neither branch is reachable in ink: no provider in the registry
declares that auth type, so the single write site for the pending auth type
cannot produce it, and the external-auth state those screens read is
assigned null at both of its write sites. Record the check so the omission
is not re-reported as a gap.

The MCP server startup approval in the same bullet did survive: ink opens
that dialog whenever its approval queue is non-empty and this renderer has
no counterpart, so it stays.

* fix(cli): ask for approval of a project's gated MCP servers in OpenTUI

A server list checked into a project was never offered for approval in
this renderer, so a gated server stayed silently disconnected and
nothing told the user why or what to do about it. ink opens the dialog
whenever its approval queue is non-empty.

The queue, the decision that persists against a hash of the config, the
un-gating and the reconnect all live in a renderer-agnostic hook, so
this is a view and a mount point rather than a second copy of the
policy. It ranks above the shell and tool confirmations, as in ink.

Geometry was measured against ink at a hundred columns rather than
assumed, and the first attempt was wrong twice: inset three with a box
one narrower than the shared popup width, and numbered rows. Declining
lands on the same composer and footer row in both legs. Two residuals
are recorded instead of matched — ink's right border is clipped away by
its own overflowing margin, and one wrapped body line carries an extra
leading space here.

ChiGao e09c461a92 fix(cli): restore OpenTUI banner, footer, and loading states; fix the OSS mirror flavor (#11437)
* fix(cli): restore banner, footer, and loading states in the OpenTUI shell

The batched OpenTUI migration restructured the original single-file backend
into modules and dropped three user-visible pieces of the chrome along the
way: the startup banner, the bottom status line, and the responding
spinner. The OpenTUI renderer therefore booted into a screen that looked
nothing like the ink one it was meant to replace.

Rebuild all three as their own modules and mount them in the app shell,
following the ink layout: banner at the top, loading indicator above the
composer, status line at the bottom.

Two defects carried over from the original implementation are fixed rather
than copied. The context-usage label was missing its percent sign, and the
approval-mode colour check compared against a label that never matched, so
the auto-edit mode fell through to the default colour.

The context-file count is intentionally not restored: the shell no longer
tracks it and the current ink footer dropped it too.

* fix(cli): tick the OpenTUI spinner at the rate ink uses

The restored spinner ran at 120ms, carried over from the pre-batch
implementation, while the ink responding spinner it mirrors runs the same
frame set at 80ms and the existing OpenTUI compaction spinner does too. The
same animation therefore looked visibly slower under one renderer.

Name the interval and set it to the shared rate. The frame set itself is
unchanged.

* fix(release): sync the OSS mirror by what the tag shipped, not by a variable

The workflow that mirrors a release to Aliyun OSS decided whether to expect
the bun/OpenTUI preview archives from a repository variable. A repository
variable describes the default branch, while the checkout and the downloaded
assets come from the tag being synced, and the workflow can be re-dispatched
for any tag. Re-syncing a tag cut before the preview flavor existed therefore
asked that tag's own verify script for archives the release never shipped:
v0.22.3 fails because its script does not know the flag at all, and v0.23.0
fails on a missing checksum entry.

Derive the flag once from the archives actually downloaded and let all three
consumers read it, so the mirror follows the release instead of the branch.

Two related gaps in the same gate are closed here. The test covering it
asserted only the variable name, so inverting the comparison and silently
changing the flavor's default polarity stayed green; it now pins the
operator. And the variable appeared in no documentation, so an operator had
no way to learn that leaving it unset is what keeps the flavor off.

* fix(cli): source the OpenTUI chrome from main's shared helpers

The restored banner, footer, and responding indicator had grown private
copies of mappings main already owns, so the two renderers could drift.
Route the approval-mode label through formatApprovalModeName, extract the
context-usage format and version-label rules into ink-free helpers both
trees consume, and take the spinner frames and loading phrases from the
shared constants and cycler.

Also truncate the footer rows and the indicator phrase to the terminal
width so a long branch, path, or phrase cannot wrap the chrome mid-turn,
and read typed Config accessors in the banner instead of structural
casts and a manual package.json read.

ChiGao 7023bba760 feat(cli): OpenTUI parity closeout (dialogs, composer, shell mode) (#11152)
* fix(cli): render the OpenTUI confirmation as one surface and bound the transcript flood

The mem0 confirmation scenario exposed three stacked gaps in the OpenTUI
renderer: the awaiting-approval path never reached the transcript model,
the expanded dialog body overflowed a fixed alt-screen viewport, and the
confirming card duplicated the payload the dialog already carries.

Emit confirm/confirm-resolved transcript events from the real scheduler
awaiting path, render the expanded body as a tail window budgeted against
the terminal height (alt-screen has no scrollback to fall back to), let
the pending card yield its description to the dialog, and cap every tool
card description to a bounded head with ink's own hidden-tail vocabulary.
A shared config.initialize() once-guard stops submit-time "Chat not
initialized" races, and a batch where every call was cancelled now ends
the turn without a follow-up model request, matching the ink stream.

The mem0 e2e post-approval wait moves to request bodies so it does not
depend on raw pty bytes; both legs pass all five scenarios.

* fix(cli): auto-open the OpenTUI auth dialog at boot (U-6)

Ink's boot auto-open is two triggers: no auth type configured (useAuth
initial state) and the one-shot startup authError
(useInitializationAuthError); shouldOpenAuthDialog is dead in production
code. The OpenTUI entry now computes that request once and seeds the
shell's dialog state with it, and the auth dialog surfaces the startup
failure through its existing error surface. Also repairs the entry
fallback-contract tests, which had been failing since f6213a18cd because
their mock config lacked initialize for the shared once-guard.

* fix(cli): drain deferred OpenTUI update notifications on idle (G-3)

Ink flushes handleAutoUpdate's pendingNotifications when the turn returns
to idle; the OpenTUI entry only kept cleanup, so a mid-turn update notice
sat queued forever. Hold { cleanup, flush } in a ref and flush when
live.streaming flips false, mirroring AppContainer's idle effect. The
check bootstrap, banner slot, and registration were already renderer-
neutral on main — the ledger's G-3 gap was the drain only (Decision 9).

* fix(cli): route OpenTUI settings sub-dialogs and own the composer fill (U-9)

The mount's fillInput/onSelectSetting seams existed since Batch 4 but the
shell fed neither, so settings sub-dialog rows reported an unmounted
dialog and the arena picker's fill was reported lost. The shell now
routes ui.theme/editor and the fast/vision model rows like ink's
DialogManager, and fills the composer through the entry-owned handle via
the polling injector (the picker detaches the handle before remounting
the prompt). With an owner present a named selection no longer closes
afterwards — the owner replaces the request, and closing would clobber
the dialog it opens (Decision 10).

* feat(cli): OpenTUI follow-up suggestions with the ghost placeholder (U-7/G-2)

Port the ink follow-up suggestion feature: the entry generates on the
streaming→idle edge through a new useFollowupSuggestionGeneration hook
(ink's gate set verbatim; abort on every turn boundary and unmount), and
the composer consumes it via the shared renderer-neutral controller —
ghost placeholder, Tab/Right/Enter accept into the buffer without
submitting, typing dismisses, submit clears.

* fix(cli): correct WaitingCallInfo import source in follow-up generation

WaitingCallInfo lives in live-session.ts, not live-session-model.ts; the
wrong source only surfaced under tsc because the hook never calls the
type at runtime. Also give the parked-confirmation test case a
well-formed WaitingCallInfo and pin the it.each table to
Partial<FollowupGenerationParams> so the per-case unions typecheck.

* feat(cli): record OpenTUI steering hops for /resume (U-32)

Ink's steering accept() writes each surviving steered message through
recordMidTurnUserMessage so a session resume replays the mid-turn API
shape (user parts riding the same Content as tool results); the OpenTUI
port carried the user echo but never recorded, leaving steers invisible
to /resume. resolveSteeredPromptParts now collects per-message
recordings alongside the echo events — same membership as the echo, so
a declined message is neither echoed nor recorded — and the drain loop
records them at the commit point, after the restore check: a restored
(aborted) hop records nothing, keeping the all-or-nothing contract.

* fix(cli): join the OpenTUI queue Esc-restore with a blank line (U-11)

ink aggregates popped queue texts with '\n\n' everywhere
(aggregateUserMessages, getQueuedMessagesText), matching the model-side
steering join; the OpenTUI popQueue used a single newline. Align to the
blank line. ink's peer and slash-command queue filters have no OpenTUI
counterpart to port: the live queue only ever holds plain composer text
(slash commands defer in the shell instead of queueing) and peer
messaging has no OpenTUI queue.

* feat(cli): render the four command cards in the OpenTUI transcript (U-34)

advisor, away_recap, arena_agent_complete and arena_session_complete
previously projected to null, so /advisor, /arena and /recap output was
invisible on OpenTUI. Each kind now carries a structured stream event
through the fold into a dedicated transcript row mirroring the ink
component shapes (recap gutter with bold label and italic body, advisor
markdown card, arena status/token/tool lines and comparison sections).
Status colors map onto the live palette so rows track theme swaps; the
arena comparison helpers are mirrored from the ink card. tool_use_summary
and diff_stats stay explicit no-ops (no OpenTUI writer for either), and
the kinds remain live-only: neither renderer replays them on resume.

* feat(cli): add the OpenTUI ! shell mode (U-33)

Empty-buffer `!` toggles shell mode (Esc exits), the chrome shows the `!`
prefix, slash dispatch stays first, and a submission runs through a thin
executor over core's ShellExecutionService — a `$ ` command row plus a
synthetic run_shell_command card on the transcript, with the command+result
injected into the LLM history via ink's shared processor.

* fix(cli): close Batch 10 review-round findings on the OpenTUI surface

- Reconciler crash: stop nesting <text> inside <text> in the theme,
  permissions, settings, and MCP dialogs (five sites, one mechanism).
- Shell mode: derive the card id from a UUID so two commands started in
  the same millisecond cannot collide, and report generic tool-end
  summaries so the `!` card no longer prints the command twice.
- Confirmation body: ignore ctrl-s on a body that already fits — the
  expanded tail window can be shorter and would silently drop head rows.
- Transcript replay: pass mid_turn_user_message through to /resume while
  side-band subtyped user records stay skipped.
- ensureConfigInitialized: keep a settled failure cached (core never
  retries initialization) so later submits surface the real cause, and
  correct the stale re-entry rationale in the comments and design doc.
- Tests: first mount coverage for transcript-view and transcript-adapter,
  the idle-flush hook extraction with its own suite, shell-mode id
  uniqueness, and the fitting-body ctrl-s guard; the gating spec's
  turn-done marker moves onto the waitForScreen channel; revert an
  unrelated SKILL.md formatting drive-by.

* fix(cli): close two round-2 review findings on the OpenTUI surface

- Restore the dim styling of the permission-scope description, which the
  nested-text fix had flattened into the label color.
- Add a direct-drive pin for the cached rejected initialization: core flips
  `initialized` before awaiting the flight, so a re-entry after a settled
  failure reports "Config was already initialized" instead of the real cause.
  The existing submit-path test masks this because its mock rejects with the
  same error on every call.

* fix(cli): restore ink parity on the scope row and the theme preview diff

Two round-3 review corrections, each verified against ink's own code:

- The permission-scope label goes back to the single-string form
  (`${label}    ${description}`, one colour). ink's RadioButtonSelect
  renders the regular path as a single <Text color={titleColor}> and
  PermissionsDialog builds that label with four spaces, so the row-box
  with a dim description diverged twice from ink; the nested-<text>
  shape it replaced never rendered at all.
- THEME_PREVIEW_DIFF's hunk header declared two lines per side and
  supplied one. ink's DiffRenderer tolerates that header; OpenTUI's
  <diff> parser rejects the hunk and the preview pane rendered an error
  string instead of the diff. Counts corrected to -1,1 +1,1; rendered
  output is unchanged because neither renderer displays the header.

* fix(cli): land review round-3 on the OpenTUI surface (13 Criticals + 16 Suggestions)

Criticals: settings sub-dialog routing + arena composer fill owned by the
shell (U-9); confirm-resolved carries the approved/rejected outcome so a
No/Esc decline is not mislabeled; the mid-turn steering restore re-queues
texts when the abort lands behind a resolved hop; displayText replay and
attachment placeholder on /resume; tool-card description stays visible for
confirmation types the dialog does not carry; wide-char rows measured in
display columns for the content caps; followup ghost abort/dismiss split;
Esc in shell mode exits and interrupts in one keypress; status text shows
Shell mode; stale-dropdown guard for the `!` toggle; bidi stripping on
arena rows; boot-seeded auth error keeps Esc dismissible; pending-card
gating.

Suggestions: POSIX wrap closes its brace group on its own line (trailing
comments no longer swallow the wrapper), shell status summary is
cancelled for user aborts, shell lane reuses the dispatcher's admission
rule and passes cwd/signal/config through, pwd/history writes only on the
chat that started the command, `!` child width mirrors ink, expand guard
for short terminals, expanded tail keeps its hidden-rows label, in-place
settings flips invalidate the suggestion effect, MCP fixture pins both
name fields, design-doc coverage paragraphs updated to the extracted hook.

14 remaining Suggestion-level items are recorded as U-39 in #8662.

* test(cli): pin idle slash dispatch over the shell lane in shell mode (U-33)

The mid-turn tag and the drain's shell branch are pinned by the ?btw and
PATH cases; this adds the idle precedence half of the routing.

* test(integration): align mem0 long-confirmation oracle with both renderer legs

The expanded-state oracle asserted a whole-viewport absence of the
hidden-tail label, but OpenTUI's fixed alt-screen viewport keeps the
transcript's own capped copy of the payload (with its label) above the
dialog, so the negative check could never pass on that leg. Scope the
label assertion to the confirmation section there, and keep the
whole-screen form for ink, whose expanded dialog scrolls the section
heading out of the viewport. The OpenTUI leg also needs a taller PTY
(his expand guard only opens ctrl-s when the tail window reveals more
rows than the collapsed head), while ink derives its cap from terminal
height and must stay at the historical 38 rows for the bounded-view
oracle to trigger.

* fix(cli): honor the ctrl-s promise and keep pending payloads approvable

TextBody only offers ctrl-s when expansion actually reveals rows the
collapsed window hides, and labels the expanded view's dropped head rows
as first-N instead of last-N; a pending tool card keeps its own bounded
row budget instead of the settled 5-row cap, so the tail of the payload
being approved stays on screen (round-7 R5-1/R5-2/R5-9).

* fix(cli): hold plain prompts behind running shell commands and harden the shell lane

Four defects around the `!` shell lane and the deferred-command queue:

- A plain prompt typed while a `!` command was running or a slash
  submission was streaming now waits in the deferred queue instead of
  racing the stream, and is routed to the prompt turn when the lane
  frees; slash-form input stays exempt because the dispatcher admits it
  itself.
- A drain pause (a queued turn/dialog that owns the UI) no longer
  re-arms the drain's completion bump, which used to run the queue
  remainder before the turn or dialog it waits for even started; the
  bump still re-arms for entries that arrive mid-drain.
- executeUserShell is async and its seam reports a rejection instead of
  letting it strand the shell gate, and both chat-identity reads are
  guarded so an uninitialized or swapped client can neither throw nor
  inject a stale session's output into a fresh chat.
- One physical `!` keypress toggles shell mode once across press and
  release events.

Pinned by unit tests in opentui-app-shell.test.tsx, shell-mode.test.ts,
input-prompt.test.tsx; every fix is mutation-verified.

* fix(cli): restore steering texts when the abort lands after the hop

An abort that arrives after the streaming hop already resolved used to
fall through the same path as a normal end-of-turn, so the steering
texts the model never saw were consumed without ever reaching it. The
branch now restores the steering queue and only writes the collected
function responses back to history, mirroring the pre-hop abort path.

* fix(cli): let Esc close the auth dialog when boot already seeded the error

When the boot flow failed before any auth type existed, it opened the
dialog with the diagnostic already set. Esc ran the normal handler,
which fell through to the unauthenticated arm, overwrote the boot
diagnostic with the must-connect message and wedged the dialog shut.
Esc now closes first when the displayed error is the boot's own.

* fix(cli): close a dangling line continuation before the shell terminator (R6-8)

A `!` command ending in an odd run of backslashes escaped the appended
`;` into a literal argument, so the wrapped execution ran a command the
user never wrote (`ls \` became `ls ';'`). Close the continuation with a
newline before appending the terminator, in both the ink and OpenTUI
shell lanes.

* fix(cli): carry held-prompt attachments through the drain and re-check the gate between entries (R5-5', R6-4)

Round-5's fix rerouted prompts queued behind a running `!` command into
the drain, but dropped their image attachments on the way: the queue
entry carried only the text. Store the attachments on the entry and pass
them back to onSubmitPrompt at drain time.

And the drain checked the holdsUi gate once before the loop, so an entry
awaiting inside the loop (a `!` command finishing, a dialog opening)
let the remaining entries run against a gate that just closed. Re-read
the gate before each entry and re-queue the remainder paused — same
shape as the holdsUi branch, so the dep change that closed the gate is
what resumes the batch.

* fix(cli): write the completed batch to history on both abort windows, gate mid-turn recordings on delivery, and gate onComplete on the signal (R6-5, R6-7, R6-6)

The R5-4 history write covered only the abort-after-clean-hop window: an
abort landing inside the @-read hop returned restore() and fell through
with no addHistory and no return, so the loop sent a continuation on the
dead signal and dropped the batch's function responses. Hoist the abort
check above the restore branch so both windows write history and return.

The U-32 mid-turn recording was written before the continuation send was
delivered — a send that throws would persist a mid-turn user message the
model never saw and never hand the drained texts back. Stash the
recordings at the sampling boundary and flush them only once the
continuation send yields or completes cleanly; on a throw or an abort
before that, restore the raw texts to the queue instead (ink records
from onDelivered).

And the abort paths inside the prompt generator end with a normal
return, so runTurn's seq guard alone fired a command's onComplete for a
turn the user cancelled with Esc — gate it on the abort signal too. A
decline of every confirmation without Esc stays a completed turn.

* fix(cli): dismiss submitOnAccept ghosts, fold multiline card descriptions, re-arm early-input injection (R6-1, R6-2, R6-3)

* fix(cli): delete unreachable textarea submit route (global Enter handler always wins)

* fix(cli): budget a pending tool card below the confirmation dialog footprint

The confirmation dialog renders in flow beneath the transcript on OpenTUI's
fixed alt-screen viewport (ink scrolls overflow into scrollback). A pending
card left at maxHistoryItemRows (terminalHeight * 4 — 320 rows at h=80)
pushed the dialog's outcome list, hidden-lines label, and ctrl-s hint off
screen: the mem0 interactive e2e timed out waiting for the hint three runs
in a row. The pending description budget is now viewport-aware
(pendingCardMaxRows) and reserves room for the dialog, the transcript rows
above the card, and the card's own chrome; short payloads render in full
(R5-9 preserved) and short terminals fall back to the settled cap.

* fix(cli): budget a pending card for the dialog's expanded payload

The pending-card budget bounded only the dialog's collapsed footprint, so
the mem0 confirmation (whose dialog body duplicates the card's ~3.9k-char
description) expanded past the 80-row viewport and its tail never came on
screen. pendingCardMaxRows now also reserves rows for the payload the
dialog will render, estimated from the card's own description width; the
collapsed-dialog bound keeps MCP-native cards (dialogs without args)
generous, and short terminals still fall back to the settled cap.

ChiGao 9c320cb0cc fix(cli): OpenTUI transcript visibility for commands, /clear and steers (#10947)
* docs: correct two batch-8 follow-up notes

The U-26 section still read "Registered as U-26" after that number was
retired and folded into U-12 the same day, so it pointed at a record
that does not exist. The U-27 section said ink's warning names the
formats the model cannot read; the shared warning text names the
formats the pipeline supports. The second error mattered more than the
wording: porting U-27 faithfully would have read as a behaviour change
against a claim that was never true.

* fix(cli): OpenTUI transcript visibility for commands, /clear and steers

The renderer kept two histories and painted one. Everything a slash
command reported was recorded in a store no view reads, so a command
ran, changed real state, and left the screen untouched. A recorded item
now becomes a transcript row at the moment it is recorded, through one
mapping that decides every kind the command layer can write and is
checked for exhaustiveness at compile time; the kinds the live model
turn already renders are explicit no-ops with the reason beside each,
so nothing paints twice.

Clearing the conversation emptied the recorded history and left the
visible transcript standing, which the session-switch contract already
described as clearing both. Clearing also exposed a crash hiding behind
the invisible transcript: the command context handed out one host
method detached from its receiver, so the command threw before it
cleared anything and the error was the only thing on screen.

A message typed while the model is still working now appears as its own
row once the turn accepts it, with its own read cards immediately
before it, in the order the existing renderer produces. Previously the
queue counter dropped and the text disappeared without a trace.

Submitting an image the pipeline cannot read now discloses the
supported formats on both the fresh-submit hop and the mid-turn one;
such an image previously reached the model with no notice at all.

Four kinds the existing renderer draws with dedicated components are
written under this renderer too and stay invisible, exactly as before:
each needs a row shape this transcript does not have, and the replay
path never handled them either, so leaving them out keeps live and
replay consistent. The design doc names every producer line and
registers them, with four further findings, as follow-ups.

Closes U-12 (visible half), U-27, U-28, and the two gaps this change's
own smoke turned up. Part of #8662.

* fix(cli): one user row per command submit and per duplicate steer

Project-on-write made the recorded invocation visible, which exposed a
second user row behind every submit_prompt outcome: the live turn echoed
the expanded content the user never typed, where ink adds only the
invocation row. Suppress that echo at the submit seam. Steering the same
text twice also rendered two rows where ink renders one, because stream
echoes never pass through either addItem implementation — collapse them
at the fold, the one chokepoint both echoes share.

Adds the instruments review round 1 asked for: the fileData image
disclosure and its per-message attribution in the steering drain, ink's
blocked-prompt text and redaction at the projection site, the host state
forwarded into the projector context, and the host and seam-callback
identities the transcript memo preserves.

* docs: Record when the batch-9 interactive spec actually runs

* docs: Name every lane that collects the batch-9 spec

The design doc recorded the new interactive spec as collected only by the
opentui e2e job. The ink lanes pass the whole integration root with two
excludes, so they collect it under ink as well — a wrong map that would send
a maintainer bisecting a red ink shard to the wrong job.

ChiGao a6dcae2ce5 feat(cli): Open OSC 8 links with a plain click in VP mode (#10979)
* feat(cli): Open OSC 8 links with a plain click in virtual-viewport mode

Virtual viewport turns on SGR mouse tracking, which makes the terminal
stop handling OSC 8 hyperlink clicks — so links could not be opened at
all in that mode. Read the URL from the composited frame cell under the
pointer and open it on a plain left click, deferring the open by the
multi-click window so drag-to-select and double/triple-click word/line
selection keep their priority. A right-click raises an in-app context
menu (Open Link / Copy Link Address / Copy Selection).

Gating is unchanged for other cohorts: non-VP and mouse-tracking-off
users keep native terminal link handling (the controller is inert
outside VP+mouse), and the OpenTUI renderer has its own link path and is
not wired into this one.

* fix(cli): guard context-menu executeIndex against same-tick double Enter

executeIndex cleared menu state asynchronously but left the synchronous
menuRef mirror live, so two Enter keypresses dispatched in one stdin
chunk (before React re-renders) ran the item's onSelect() twice — opening
the browser twice for "Open Link". Null the mirror before the async
setMenu, mirroring the guard closeMenu already applies.

ChiGaoandShaojin Wen a2ed9928bb fix(cli): Align OpenTUI mid-turn submit and exit with ink (#10883)
* docs: Design the OpenTUI submit and exit parity batch

Six gaps where the ink renderer has a mechanism the OpenTUI port carried
only the shadow of: bare quit tokens, the missing client shutdown signal
on exit, mid-turn steering that skips the vision bridge and @-expansion,
an e2e leg that cannot hold a stream open, and the noflicker scenario's
outcome being judged globally.

* fix(cli): Let bare quit tokens reach the OpenTUI dispatcher

Typing `exit`, `quit`, `:q` or `:wq` in the OpenTUI renderer sent them to
the model as prose, and mid-turn they queued behind the stream instead of
stopping it. ink rewrites that family to `/quit` ahead of its message
queue; the port had the exemption but not the rewrite, so the gate let a
quit through only in the one spelling that already looked like a command.

* fix(cli): Stop background work before an OpenTUI session exits

Every OpenTUI exit drained the cleanup chain without first telling the
client that shutdown was imminent, so memory extract, dream and skill
review could spawn new agent work during the exit window — the one thing
that keeps a process from finishing. ink makes that signal on its quit
path; here all three exits share one drain, so the signal belongs to the
drain.

* fix(cli): Resolve OpenTUI mid-turn steering like an idle prompt

Text the composer queues while a turn runs reached the model raw: no
`@path` expansion, no read deadline, and no prompt-side vision bridge, so
an image could ride as `inlineData` to a model that cannot read it while
ink converts it and discloses the egress. Both hops now resolve a steered
message the way an idle submission does — expansion under ink's 10 s read
timeout, then the bridge — and a turn that dies mid-resolution hands its
texts back to the queue instead of losing them.

The bridge can also pick a full-turn vision model mid-turn; the rest of
the turn stays on it, including the model named in the mapper's own
notices, so the override is read per boundary rather than once per turn.

Part of U-21 and U-25 in #8662.

* test(cli): Pin the exit check between queued command dispatches

Round four of #10831 noted that the deferred-command drain checks the
shared exit latch twice but only the pre-loop check had a test: deleting
the per-iteration one left the suite green. This adds the crossing that
check exists for — the exit begins while an earlier command is still
awaiting its outcome — by flipping the latch inside the first dispatch and
requiring the second never to run.

Part of U-23 in #8662.

* fix(scripts): Require the offline parity gate's base to fail

The offline no-flicker scenario runs a fixture emitter that injects clears
and unbalanced DEC 2026 as its base side, yet the runner accepted both-pass
as a passing outcome. A base fixture that stopped emitting its defect would
have kept the gate green while proving nothing at all.

Scenarios can now declare their base a defect fixture with
`expectBaseFailure`, which turns both-pass into a failure — set on the
offline scenario only, since the credentials scenario compares against ink
and the self-test override path asserts both-pass deliberately. A gate
failure names its own cause in the report and on the console line.

Part of U-15 in #8662.

* test(integration): Hold the fake model stream open mid-turn

Every mid-turn behaviour in the submit path is invisible to a test that
cannot say "the CLI is streaming right now": the fake server wrote each SSE
chunk synchronously, and awaiting its handler holds a turn only before the
first byte. FakeOpenAIResponse gains holdAfterChunks + holdUntil, so a test
can stop the stream after a delta it can see on screen and release it on
purpose. close() tears held connections down, which is pinned because
"the run cannot hang on my instrument" is exactly the claim an instrument
like this must not make untested.

Four cases use it, one file for both renderers: /quit and a bare `exit`
typed into a live stream, a slash command held back mid-turn, and a steered
@file mention. The last two assert on captured request bodies rather than
screen text, because OpenTUI repaints by diffing cells and renders no slash
command output at all.

Closes U-24 in #8662.

* docs: Record the batch-8 measurement boundary and adjacent gaps

The design doc said each new case was checked red-then-green before its own
fix commit. What was done instead is mutation probes, and two of the four
leave the OpenTUI leg green — so replace the claim with the measured table
and its cause: a submission that skips the mid-turn gate is steered into the
same turn and still reaches the model only after the held turn ends, and
process teardown closes the socket however the turn ends. Both halves are
pinned at unit level, which is a different claim.

Register the three gaps this batch found and deliberately did not fix:
steered text has no transcript echo (U-26), neither hop warns about an
unsupported image format (U-27), and OpenTUI keeps slash command output in a
history no view renders (U-28) — the last is why the first version of the
deferral case failed for a reason unrelated to the gate under test.

* docs: Correct the mid-turn requeue rule in the batch-8 design

The design doc said a timed-out mid-turn read hands its text back to the
queue. The code requeues on an abort only — a timeout or a declined read is
dropped with a warning, which is what ink does and what the steering test
pins — so the sentence described a behaviour the port deliberately does not
have.

* docs: Measure both of the batch-8 drain's exit-latch checks

Deleting the in-loop check reddens exactly the test written for it, and deleting the
pre-loop check reddens nothing at unit level. The pair is what makes the documented
redundancy a measurement instead of an argument, so both now sit in the coverage
boundary alongside the two mutations the E2E leg cannot see.

b5560494b2 fix(cli): close OpenTUI submit-path gaps, restore its E2E leg (#10831)
* fix(cli): give the OpenTUI submit path ink's provenance, indicator and mid-turn gate

Three gaps left the OpenTUI interactive E2E leg red while the ink leg stayed
green on the same run:

- a composer submission never carried its raw text, so UserPromptSubmit hooks
  saw no submitted_prompt (and the external-context auto-recall keyed off it
  never fired), and `@path` mentions reached the model unexpanded;
- the approval-mode status text was computed but never rendered, so a YOLO
  session showed nothing to wait on at startup;
- a slash command submitted mid-turn was dispatched at once instead of waiting
  for idle, so `/compress` raced the still-open stream and silently did nothing.

The mid-turn gate is the ink rule: only a command that opted into
canRunDuringStreaming runs while a turn responds, everything else the
dispatcher would take is held and drained on the idle transition.

* ci(e2e): Put the OpenTUI interactive e2e leg back in CI

#10829 removed the `e2e-interactive-opentui` job to keep main green, and
registered its removal as gated on the parity gaps the leg surfaced (#8662
U-17…U-20). The commits above this one close them: the approval-mode
indicator is drawn, `submitted_prompt` rides the first send, `@file` goes
through query preparation, and a slash command submitted mid-turn waits for
idle instead of racing the open stream.

Restoring the job verbatim rather than rewriting it: nothing about its
runtime contract was wrong, and the pinned Bun version plus the strict
renderer pin are what make a silent ink fallback fail the leg.

The four failures traced to four gaps, not the three #10829 recorded — the
context-compression case needed its own mid-turn gate. The context-compress
file additionally carries a fifth case (`/compress` with trailing
instructions) that was red on the first two `main` runs and passed the
third: it submits mid-turn too, so it is the same mechanism, and the leg
that runs the whole directory is what judges it.

The design doc named the leg as removed in two places; both now describe a
leg that reported the gaps, left CI, and came back with them closed.

* fix(cli): Keep mid-turn @ mentions out of expansion and pin the mode chrome

A submission that arrives while a turn responds becomes steering, which
carries text only, so expanding its @ mention read files the hop would
drop. A declined expansion also stayed silent: the composer cleared and
nothing reached the model. Report the failed-read reason instead, and pin
the approval-mode indicator plus all three submit-path rules in units.

* fix(cli): Expand OpenTUI @ mentions in the stream layer; unblock mid-turn quit

The commit above kept mid-turn @ mentions out of expansion on the stated
premise that steering drops the expanded payload. That premise was wrong:
ink expands steered messages too (resolveSteeredMessages), so the
composer-side guard was a parity loss rather than a parity guard. Expansion
moves to where a prompt enters the stream, which is where ink does it for a
fresh turn (processQuery): the idle submit and the queued text that becomes
the next turn are both covered, the transcript keeps what the user typed,
and the read cards ink renders through handleAtCommand's addItem now render
here as settled tool-start/tool-result/tool-end events. A declined expansion
is the failed read, and it reports itself on that card instead of sending the
unexpanded text to the model. The follow-on turn built from the mid-turn
queue carries the raw text as UserPromptSubmit provenance for the same
reason ink does.

Text drained as in-flight steering still rides raw. ink expands that hop
with a 10s read timeout and a queue restore on cancel; reproducing it
half-way under a red CI leg was the worse option, so the divergence is
stated in the live-turn module docstring and registered in #8662 instead.

Review round 2 also found a blocker in the mid-turn gate this branch added:
the quit command carries no canRunDuringStreaming opt-in, so /quit and /exit
typed during a response were queued until it ended. ink runs its quit family
ahead of the message queue precisely so an exit can stop an active stream,
and its quit action cancels the ongoing request before the exit drains. The
gate now exempts the resolved quit command, which covers /exit as an altName,
and the shell interrupts the turn before handing the exit to the entry so the
cleanup drain does not race a stream that is still writing.

Pinned in units at both seams and mutation-checked: the gate answers from
the real built-in quit command, the shell interrupts before it exits, the
stream layer expands a string prompt and reports a failed read, and the
queued follow-on turn arrives raw with its provenance. No ink-path file is
touched.

* fix(cli): Make the OpenTUI held-command drain idle-safe and gate @ expansion on provenance

Review round 1 on the submit-path work found the mid-turn gate's two queues
leaking in both directions, and the @-expansion hop running on content it
should never touch.

The held-command drain was edge-triggered on `streaming` alone. The gate
awaits the command registry, so its verdict can resume after the turn it was
asked about has already ended, with a stale `streaming=true` closure, and push
into a ref that nothing re-reads until some future streaming transition — a
command submitted against an almost-finished turn stranded while the session
sat idle, and a retyped copy ran twice. A push now bumps a revision nonce that
sits in the effect's dependency array, which is ink's own shape: its
useQueuedSubmissionDrain gates on the queue length and re-arms through
queueDrainNonce. The queue itself stays a ref on purpose, so re-queueing behind
a turn or a dialog does not re-trigger the effect and drain straight into the
stream the previous outcome just opened.

That same drain ignored dialogs. An open_dialog outcome did not pause the
replay loop, so a second command's setDialog() overwrote the first and a
command the user was told would run vanished; and the loop replayed held
commands over a dialog the user was already in, since ink's
shouldDrainMessageQueue gate on dialogsVisible had no counterpart here. Both
are one change: open_dialog pauses the loop the way submit_prompt already did,
and `dialog` joins the drain's gate and dependencies so closing a dialog wakes
the remainder instead of stranding it.

Quit left both queues behind. The interrupt that stops the turn before the
exit drains is also the idle edge that wakes the held-command replay, so a
mid-turn /quit ran queued commands against a session already tearing down;
and the same abort's finally promoted the live turn's steering queue into a
brand-new model turn — a UserPromptSubmit hook and an API request after the
user asked to leave. The quit branch now discards both first. The steering
queue goes through the onPopQueue seam the entry already wires to
live.popQueue, placed in the shell rather than in the entry's handleQuit so
the discard strictly precedes the abort and the ordering is witnessed:
OpenTuiEntryApp is not exported and its test file mocks both the shell and the
hook, so an entry-side call would have shipped untested.

@-expansion was gated on the prompt's shape, never its provenance, so it ran
on every string prompt reaching the stream layer — including the payload a
slash command generates, which ink never expands (processQuery returns the
submit_prompt branch before its isAtCommand check). `/remember my friend
@alice reviews my PRs` therefore had `alice` treated as a file: either the
model turn ran on silently transformed content, or a failed read declined the
expansion and the command sent nothing while still reporting success.
Expansion now requires submitted_prompt provenance, which both user-typed
paths carry and generated content does not.

Also corrected: the expandAtMentions docstring claimed ink parity for the
mid-turn steering hop that this code path does not implement, contradicting
the live-turn module docstring in the same commit range.

Pinned with seven mutation probes, each killed and restored: the nonce
dependency, the open_dialog pause, the dialog gate, both quit discards, the
submit_prompt requeue guard, and the idle-submit options hop (which had no
unit coverage at all — the reviewer's mutation severing it left 49 tests
green).

Not addressed here, both recorded on their threads and in the deferred queue:
a held command still misses the boundary where a turn ends by promoting a
queued prompt, because setBusy(false) and the successor's setBusy(true) batch
into one commit and `streaming` never renders false — closing that needs an
idle barrier across live-turn, the entry and the shell, a redesign of the seam
rather than a fix to it; and the expansion hop has no prompt-side vision
bridge, which OpenTUI has never had.

* fix(ci): record the restored OpenTUI e2e leg in the workflow size baseline

Restoring the OpenTUI interactive e2e job that #10829 removed grows
e2e.yml by 4454 bytes, past the 21437+4096 ratchet. The growth is the
job block itself, not drift: bump the recorded size to 25891 in the
same PR, as the gate instructs.

* fix(cli): guard the OpenTUI held-command drain behind an exit and replay one submission per turn

Round-2 review findings:

- R2-1: the drain consulted only streaming/dialog, so the exits that
  bypass the shell's quit branch (Ctrl+C/Ctrl+D double press, render-error
  bailout) could not stop an in-flight snapshot from dispatching held
  commands against a tearing-down session. The drain now reads the shared
  exit latch at the edge and between dispatches.
- R2-2: end-of-turn replay joined every queued mid-turn text into one
  turn, so the expander's one reachable decline (an abort landing inside
  the @-mention read) swallowed the whole queue. Replay is now one
  submission per chained turn, matching ink's pop-one-per-settle drain.
- R2-3: the multimodal pass-through test now carries production-shaped
  options so the gate's string check decides (the provenance short-circuit
  no longer masks it), and its comment cites the real ink symbol.

Each fix is mutation-checked: reverting it turns the added test red.

ChiGao c3bf0fea5b fix(ci): Take the OpenTUI interactive e2e leg out of CI (#10829)
Batch 7 added a dedicated OpenTUI leg to e2e.yml. It never ran on its own
PR — the workflow triggers only on push to main, nightly and dispatch — so
its first executions were on main, where it fails deterministically: the
same four interactive files have failed across three consecutive main
commits.

The failures are not test fragility. Each one is a parity gap the renderer
still has, and the leg did its job by surfacing them:

- the approval-mode indicator is never drawn, so a user running --yolo
  cannot see which mode they are in;
- the submit seam drops submittedPrompt, so the UserPromptSubmit hook input
  loses submitted_prompt and external-context auto-recall silently no-ops;
- the live turn bypasses the query-preparation pipeline, so @file expansion
  does not work under this renderer at all.

Removing the leg keeps main green without deleting any test: the ink leg
still runs every one of these files, so nothing regresses silently. The
renderer matrix stays wired in — the e2e legs keep pinning their renderer,
and the OpenTUI side remains runnable locally through
npm run test:integration:interactive:opentui:sandbox:none. Restoring the CI
leg is gated on closing the three gaps, tracked in #8662.

The design doc claimed the build/CI batch "runs the OpenTUI e2e leg green
on CI"; that named a mechanism this commit removes, so both mentions now
match the tree.

ChiGao d7fbf305cc feat(release): add gated bun/OpenTUI preview flavor to standalone releases (#10814)
* feat(release): add gated bun/OpenTUI preview flavor to standalone releases

Phase 2 validation needs a real archive that boots the OpenTUI renderer,
so the standalone pipeline gains an opt-in second flavor instead of
replacing the classic Node.js one:

- create-standalone-package.js derives archive names from a shared
  standaloneArchiveName() helper; bun archives carry the
  -opentui-preview suffix, and bun shims default QWEN_TUI_RENDERER to
  opentui (explicit user overrides still win).
- build-standalone-release.js accepts --include-opentui-preview to
  package both flavors in one run, with per-flavor publisher checksums
  and a flavor-aware output assertion.
- verify-installation-release.js accepts the same flag so a gated
  release directory/URL and the OSS upload list both expect the preview
  archives.
- release.yml and sync-release-to-oss.yml thread the flag behind a
  vars.OPENTUI_PREVIEW_RELEASE_ENABLED gate (off by default, byte-identical
  behavior when unset); .size-baseline re-pinned in the same PR.
- Also fix a latent crash in copyOpenTuiAddon's warn-only degradation
  path, which asserted against a lib/node_modules directory it never
  created.

* feat(release): add a thin installer for the gated opentui-preview archives

The preview flavor is not reachable through the hosted installer chain,
which only packages assets for stable releases, so testers had to download
and unpack the archive by hand. This adds a scratch-directory installer
pair that resolves the platform target, verifies the release SHA256SUMS,
and unpacks into ~/.qwen-preview without touching PATH or an existing
classic installation. A local archive can be installed directly so the
path is testable before a gated release exists.

ChiGao cd1ac72874 feat(opentui): bundle assets, CI matrix and parity tooling (Batch 7) (#10770)
* feat(opentui): add the build, CI and parity tooling for the renderer migration

Batch 7 of the ink→OpenTUI migration (#8662): everything the renderer
needs to be built, verified and shipped — ink stays the default.

Bundled builds silently lose code-block syntax highlighting because
@opentui/core resolves its tree-sitter assets package-relatively, which
misses inside the esbuild bundle. Relocate the runtime assets (parser
worker, grammar wasms/scm, web-tree-sitter, native render library) next
to the bundle, and gate OTUI_ASSET_ROOT on the tree being complete for
the running platform — @opentui/core throws on any missing key, so an
incomplete relocation must fall back instead of half-configuring.
Standalone archives gain a Bun runtime (the renderer needs bun:ffi) and
per-target @opentui platform packages via the existing release
packaging, with --runtime=node restoring classic packaging.

The renderer matrix drives interactive E2E under node+ink and bun+opentui,
but Batch 6's renderer gate silently falls back to ink on an unsupported
runtime, so a green opentui leg could be a false green. QWEN_TUI_RENDERER_STRICT
turns that fallback into a loud startup failure for the matrix legs only;
user-facing default behavior is unchanged.

Parity tooling: a tui-parity workflow with component snapshots and a
no-flicker gate (zero full-screen clears, balanced DEC 2026) that runs
offline without model credentials, an ink→opentui codemod with a
self-test, the PTY/tmux comparison harnesses, and the cli scripts/ tree
is now covered by the package typecheck.

* fix(ci): build all packages in the tui-parity jobs

With prepare skipped, npm ci leaves the CLI's workspace dependencies
unbuilt, and a workspace-scoped build of the CLI alone resolves their
types from a dist that does not exist yet. The parity jobs must run the
repository-root build like the other E2E legs.

* fix(build): enforce renderer strict mode and drop musl from standalone packages

Address yiliang114's review on the Batch 7 build/CI work:

- propagate QWEN_TUI_RENDERER_STRICT into RendererSelection so the
  dispatcher also fails loudly when the OpenTUI entry returns false or
  throws, closing the false-green path in the E2E renderer matrix
- stage the OpenTUI platform packages only for the bun runtime and drop
  the -musl variants: the bundled Bun binaries are glibc-linked and
  cannot start on musl hosts, so the musl render packages claimed
  support the archives cannot deliver
- wipe dist/opentui-assets before re-copying so a stale tree from an
  earlier bundle cannot satisfy the key-existence runtime gate
- route the script-PTY capture branch through spawnScriptPty so the
  argv form follows the platform, and give it the destroy() that
  finish() expects from the node-pty-like interface
- harden pty-e2e.sh (set -euo pipefail, mktemp+trap, full TCL escaping
  of the prompt) and tmux-compare.sh (missing-binary check, mktemp+trap)
- pin the CI Bun setups to 1.3.14 = DEFAULT_BUN_VERSION so an upstream
  Bun release cannot flip the gating legs on its own

* fix(build): keep classic Node packaging as the standalone default

The temporary OpenTUI preview flavor (--runtime=bun) stays available but
no longer replaces the default release archives, keeping Batch 7 additive
for existing standalone users.

* fix(scripts): compare prettier-normalized output in the codemod self-test

Address F1 and F3 from the deep verification report:

- The self-test compared the codemod's raw output against the
  prettier-formatted fixtures/after.tsx, so 2 of 17 tests failed as
  committed. Normalize both sides through the repo prettier config
  before comparing (tests 1 and 6); the harness awaits because
  prettier 3's format() is async-only.
- Refresh the tui-parity.yml baseline entry from 2190 to the measured
  2508 bytes so the ratchet tracks real growth.

* fix(build): gate standalone opentui assets by runtime flavor

Node archives carry no opentui-assets tree at all: the renderer needs
bun:ffi, and cross-built archives would only hold another platform's
native library that the all-or-nothing asset gate could never activate.
Bun archives now prune every @opentui/core-* directory that does not
belong to the build target, dropping the build host's library from the
archive. The npm-package allowlist comment is corrected to match the
observed fallback behavior.

* test(cli): cover the OpenTUI strict-mode dispatch and e2e renderer matrix

main() now has coverage for the four dispatch outcomes: strict mode
throws both when the OpenTUI entry declines to start and when it boots
with an error, and non-strict mode falls through to startInteractiveUI.
resolveE2eCliCommand gains coverage for the opentui leg — bun on PATH
resolves to bun, and a missing bun fails with the actionable error.

ChiGaoandShaojin Wen 8051bf02bd feat(opentui): Activate the OpenTUI backend behind QWEN_TUI_RENDERER (#10739)
* fix(opentui): Drop the phantom submit_prompt result from the /goal route

goalCommand returns only goal_control or a message, so the route table
declared a result kind no code path can produce. The parity test asserts
the declared kinds by set equality, so it is updated with the registry.

* feat(opentui): Activate the OpenTUI backend behind QWEN_TUI_RENDERER (Batch 6)

Wire the OpenTUI renderer end to end while ink stays the default: the
interactive entry dispatches on QWEN_TUI_RENDERER, gated to runtimes that
can load the native FFI, and a failed renderer probe falls back to ink
silently. The entry mounts the composition root with the ink-parity seams
(runtime sidecar, session registration, update notices, two-press exit,
early-input injection, resume replay, render-error echo), a live-turn
driver folds model stream events into the transcript, and the Batch 5
deny-everything confirmation bridge is replaced with real tool / shell /
action dialogs so model turns can be approved interactively.

* fix(opentui): Fire SessionEnd hooks on the OpenTUI exit path

The ink tree registers a SessionEnd hook cleanup in AppContainer, which
the OpenTUI entry bypasses entirely — user-configured SessionEnd hooks
would silently never run under QWEN_TUI_RENDERER=opentui. Mirror the
ink cleanup in the entry's exit chain.

* refactor(opentui): Drop the dead onStreamingChange live-turn option

No caller ever supplied it: the entry syncs the host's streaming state
through the shell's streaming prop instead.

* fix(opentui): Enforce the ink-fallback contract and turn lifecycle parity

Address the Batch 6 review findings:

- llm.tsx wraps the opentui entry load/boot in try/catch — importing the
  entry evaluates modules whose module scope touches the native FFI, so a
  gate-passing runtime with a broken FFI now falls back to ink instead of
  crashing; the gate refusal reason goes to the debug log.
- startOpenTuiUI guards everything past renderer creation: a boot failure
  tears the renderer/root/runtime down and returns false.
- The live turn is generation-guarded: resetTranscript settles parked
  confirmations as Cancel (waking the scheduler queue), aborts, clears the
  steering queue, and invalidates the in-flight turn's late events and
  queue resubmits.
- Ctrl+C follows ink's handleExit cascade: close the parked confirmation
  first, interrupt an in-flight turn second, arm the two-press exit guard
  only when idle.
- submit_prompt outcomes carry modelOverride/refreshContextFilesOnWrite/
  onComplete through the shell seam into the turn (fired once after a
  successful turn, ink parity) instead of being dropped.
- ToolCard description/suffix render sanitized; compareVersions breaks
  numeric ties semver-style so a pre-release of a floor is rejected; a
  question with no options settles as cancel.
- Tests: tool-confirmation settle paths incl. the double-settle guard,
  entry fallback contract, submit-option forwarding, prerelease ordering.

ChiGao 180468306c docs(design): Align OpenTUI migration notes with the landed batches (#10724)
* docs(opentui): Record the migration status through the composition root

The design doc still described the state of 2026-08-28, with only the infra
batch landed. Record the five batches now on main, name the seams the
composition root leaves to renderer activation, and list the two items
deferred to that batch.

* docs(opentui): Record the composition-root contracts and correct stale activation scope

The design doc described QWEN_TUI_RENDERER as an existing opt-in and the
activation batch as carrying runtime fixes that already shipped in #10128.
Both drifted from the code while the batches landed, which is the kind of
claim a reviewer had to catch on #10696. State the contracts the
composition-root review settled so the activation batch inherits them
instead of rediscovering them.

* docs(opentui): Record measured runtime status and what the batch reviews kept finding

Three claims in the design doc described instruments and gates that are not in
the tree: the session-replay harness (issue #10005 is still open, nothing
measures flicker today) and plain-Node loadability, which 0.5.8 fails on Node
24 — verified locally, not just reported in review. The recurring finding
classes are recorded so the activation batch does not re-earn them.

ChiGao d6c0390816 feat(opentui): Add the backend composition root (Batch 5) (#10696)
* feat(opentui): Add composition-root error boundary, runtime, and command host

Batch 5 (slice 1/3): the OpenTUI backend has all its pieces (dispatcher,
dialogs, live turn, folding model) but no composition root that owns state
and wires them. Add the three self-contained leaves first:

- OpenTuiErrorBoundary: React boundary mirroring the ink shared ErrorBoundary
  (recordForExitEcho + consumeLastRenderError) for the @opentui/react tree.
- OpenTuiRuntime: process-level lifecycle (runtime sidecar, dual-output bridge,
  remote-input watcher, memory-pressure monitor, ordered shutdown).
- OpenTuiAppHost: concrete OpenTuiCommandHost + SessionSwitchHost — owns
  command history with faithful useHistory parity, pending/btw/session state,
  shell allowlist, idle/processing, and delegates the live transcript and
  modal confirmations to shell-supplied seams.

Host/runtime/boundary are additive and unwired (behavior unchanged); dialog
mounting and the app shell follow.

* feat(opentui): Add composition-root dialog mount and app shell

Complete the Batch 5 backend composition root: the exhaustive dialog
mount routes every OpenTuiDialogRequest to its component, and the app
shell assembles the command bridge (host + dispatcher + gateway), dialog
mount, and error boundary, wiring the composer through the gateway so
dispatch outcomes open dialogs, reach the live-turn seam, or quit.

* feat(opentui): Reserve the update-notification slot in the app shell

Adds a fixed banner slot below the transcript, hidden while a dialog is
open, to mirror the ink DefaultAppLayout so populating the parity gap
(G-3) later does not re-open the shell layout.

* refactor(opentui): Keep command loading in slash-dispatch, drop its dead dispatch chain

executeSlashCommand and its resolution/mapping helpers were superseded by
OpenTuiSlashDispatcher and the slash gateway; no production path reached
them. slash-dispatch now exports only the loader that commands-dispatch and
the composer still consume.

* fix(opentui): Make the composition-root seams fail safe

The confirmation bridge auto-denied only the empty command list, so the
non-empty list the dispatcher actually awaits left a promise nothing would
ever resolve — hanging the dispatch loop and the gateway busy flag for the
rest of the session once the shell is mounted. It now denies every request,
matching the action-confirmation branch, and the pending-resolver slot it
never used is gone.

Composer image paths no longer flatten into an invented `[image] <path>`
text part that nothing parses; they travel to the live-turn seam as a
structured argument so the entry layer can build real image parts.

* fix(opentui): Close the composition-root gaps found in review

Extension consent stored a request that no renderer in this batch could
answer, so the caller awaited a promise that never settles; route it
through the bridge the shell already auto-denies. The host's caller-owned
steps (subscribers, onChange, transcript reset) run inside the /resume and
/branch commit window, where one throw rolls core back and deletes the
branch being displayed, so isolate them. Make the session re-key an
explicit shell seam that reports when nothing owns it, wire the
permissions dialog's directory edits to real settings persistence, and say
so when a settings row opens a sub-dialog the mount does not route.

* fix(opentui): Report an arena start the composer cannot receive

Enter in the arena model picker is the only way to start a session, and it
works by writing the command into the composer the entry layer owns. With
no composer owner wired, the dialog closed and the selection vanished with
it, so surface that the command was lost instead.

ChiGao 8096ece889 feat(cli): OpenTUI migration batch 4 — dialogs, commands, and session-rewind (#10383)
* feat(cli): OpenTUI foundation modules — theme, a11y, clipboard, keys, dialogs scaffolding

Foundation batch of the OpenTUI migration tracked in #8662. Adds the renderer-neutral foundation modules under ui/opentui: theme family, a11y (plain-text, screen-reader), clipboard, key-map, mouse hit/caret, link-click + osc8 parity, early-input, exit guard/lifecycle, kitty negotiation, event-adapter, item-projection, slash dispatch (+ command parsing), commands context/output, help content, input history, and the dialog scaffolding primitives (core/shared) with the theme dialog. Two helpers land inside ui/opentui rather than utils/ to respect the utils leaf-layer rule (#9737). Stacked on the infra batch: consumes ui/model streaming model and @opentui deps. No reachable ink code changes beyond a one-line export addition in the shared osc8 module.

* fix(cli): import originals instead of forking slash parser and dialog scope utils

* fix(cli): address R1 review findings in OpenTUI foundation modules

* fix(cli): align OpenTUI command host with the memory-file-count rename

Upstream renamed setGeminiMdFileCount to setMemoryFileCount in the command
UI contract; the rebase onto main surfaced the mismatch at build. Rename
the host interface member, the bridge wiring, the dispatch stub, and the
test mock to match.

* feat(cli): OpenTUI migration live-session and input batch

Third landing batch of the OpenTUI migration (#8662): live-session stream
fold and model, message rendering (markdown heal, MCP progressive, client
tool runs, text batching), transcript adapter with resume/session-switch,
sticky todos, the composer (input-prompt view/key/model), mouse rows and
scrollbar, unified-diff rendering, and session-compaction notice. All
additive — no reachable ink code path is touched, ink remains the default.

Carries the first consumer of the remend dependency deferred from the
infra batch, placed in devDependencies per the renderer-deps convention.
The stacked-skill completion helpers import from the relocated
ui/commands module following the upstream rename.

* feat(cli): OpenTUI migration batch 4 — dialogs, commands, and session-rewind

Adds the dialog layer and command-routing infrastructure for the OpenTUI
renderer: 19 dialog modules (auth, extensions, MCP, memory-status, misc,
model family, modes, permissions, settings, stats/skills, help overlay,
arena host, folder-trust gate), the commands registry with slash-to-dialog
routing, the commands dispatcher (action interpreter connecting the slash
gateway to the session and dialog layer), and the session-rewind viewer
with its history-folding model.

Also exports `isUserTextContent` from historyMapping so the rewind model
can classify user turns without duplicating the predicate.

Everything is additive: no reachable ink code path is touched, the default
renderer stays ink, and the dep-direction gate passes. Stacked on the
live-session batch.

56 test files / 886 tests, all green.

* fix(cli): address R2 review findings in OpenTUI foundation modules

Round-2 review fixes (17 Critical + 10 Suggestion resolved in code):

- dialogs-shared: move number-select flush out of the setState updater
  (StrictMode double-fires onSelect); split setActiveIndex (ink
  SET_ACTIVE_INDEX, lands on any in-range row) from highlightIndex
  (arrow keys skip disabled rows) so wheel navigation never sticks
- event-adapter: chat_compressed notice mirrors ink formatCount ('~'
  prefix for estimated counts); vision_bridge_notice renders
  summary\nnotice; explicit projections for task_execution /
  findings_list / terminal_image keep multi-MB payloads off the
  transcript; retry-countdown-clear forwards isContinuation
- slash-dispatch: isSlashCommandInput drops the '?' branch (ink gate
  routes ? input to the model); executeSlashCommand races the action
  against the abort signal; dialog effects carry the
  OpenDialogActionReturn payload; projected added-item text surfaces
  alongside non-handled effects (notice); message-shaped items project
  to their text; ui.history comes from env; absent sessionStats stamp
  now, not epoch; telemetry parity (recordSkillInvocation /
  recordAutoSkillCommandUsage / makeSlashCommandEvent)
- item-projection: model stats render per-(model,source) sections with
  N/A for unpriced entries; Tool Calls line uses ASCII x like ink;
  redactProxy deduplicated via systemInfoFields export
- theme: palette/syntax colors resolve through color-utils toHex before
  parseColor (ink CSS names / *bright names no longer degrade to
  magenta); unresolvable values stay unset
- key-map: kitty 'kpenter' normalizes to 'return'; resolveCommands
  exposes ink's key fan-out (Ctrl+C fires QUIT + CLEAR_INPUT)
- a11y: hardWrap delegates to wrap-ansi (word-boundary parity with
  ink's screen-reader path); markdown reducer tracks fence length,
  keeps fence-like lines literal inside fences and inner backticks in
  multi-backtick spans; stripAnsi delegates to strip-ansi plus a
  private-parameter CSI pass (SGR mouse, DEC save/restore)
- clipboard: OSC 52 write gated on a TTY (stderr preferred), tests spy
  the stream instead of writing real sequences to the runner's terminal
- exit-guard: independent per-key arm windows like ink
- dialogs-theme: diff preview pane receives syntaxStyle/filetype

* fix(cli): harden kitty probe and screen-reader writer per maintainer review

- kitty-negotiation: KITTY_REPLY_RE requires at least one flag digit
  (\d+), so an echoed bare query \x1b[?u in PTY/CI environments no
  longer resolves true and locks the renderer into kitty mode on a
  terminal that never answers queries; the accumulation buffer keeps
  only a 256-byte tail (bounded memory, bounded rescan under byte
  floods); the settle-window drain is removed — an EventEmitter data
  listener cannot consume chunks from other listeners, so late replies
  flow to the renderer's input parser like any other terminal noise
- a11y-screen-reader: ScreenReaderOutputWriter sanitizes written
  content (stripAnsi + drop bare C0/C1 controls, keep newlines) so the
  plain-text-only contract is enforced at the writer instead of
  trusting every future caller — smuggled OSC 52 clipboard writes or
  title/cursor sequences cannot execute on the main screen

* test(cli): strengthen /branch awaits handleBranch assertion with a deferred race

The previous test asserted branchNames was populated after dispatch, but a
fire-and-forget void call passed because microtasks drained before the check.
Replace with a Promise.race that proves dispatch was still pending (blocked on
the closed gate) before the gate was resolved — a void call resolves dispatch
immediately, making the race return 'resolved' instead of the sentinel.

* fix(cli): correct stale 67→69 count in commands-registry docblocks; clarify gate test

Two docblock comments said "67 modules" but the table has 69 entries (verified
against BuiltinCommandLoader.ts). Fixed to 69.

The gated-commands test comment now explains that TypeScript enforces the
CommandGate type at compile time, so the runtime loop is unnecessary — the
literal name list is the intentional guard for a bogus gatedBy on an ungated
command.

* fix(cli): address dialogs-batch self-review findings in command registry

- /theme route results include 'message': themeCommand returns a
  MessageActionReturn under NO_COLOR, so the declared results were
  incomplete
- drop the unreachable 'branch' member from OpenTuiDialogRequest and
  make routeDialogToOpenTui throw on dialog-branch instead: /branch is
  a host action intercepted unconditionally by the dispatcher (ink
  parity), and a compile-time exclusion is not expressible because
  OpenDialogActionReturn is a single interface with a union dialog
  field — the loud throw guards against a future refactor dropping the
  interception; the branch route no longer advertises a dialogs entry
  no renderer opens
- derive gate coverage from the loader instead of a hardcoded name
  list: the coverage test loads with every gate ON (plus the
  checkpointing flag the /restore factory needs) and asserts set
  equality between route names and registered built-ins — no escape
  hatches — and a new test proves every gatedBy route is genuinely
  absent from a gates-off load, so a bogus gate on an always-registered
  command fails

* fix(cli): address ytahdn independent review findings in OpenTUI foundation

All 15 findings from the independent static review verified in source and
fixed (no false positives; none deferred):

- quit effect carries QuitActionReturn.messages projected to text on a
  notice field — ink renders them via QuittingDisplay and the payload was
  permanently lost (Important #1)
- error and finished branches emit retry-countdown-clear like ink's
  handleErrorEvent/handleFinishedEvent, so a terminal event inside the
  countdown window no longer leaves a stale retry row (#2)
- projectContextUsage renders the compaction-threshold ladder and the
  per-item detail sections (tools/memory/skills, ink's sort order) when
  showDetails is on — /context detail transcripts no longer show strictly
  less than the compact view (#3)
- projectMcpStatus honors showSchema (parameter JSON under each tool) and
  showTips, so /mcp schema is distinguishable from /mcp (#4)
- SlashDispatchEnv.settings is required: the real
  CommandContext.services.settings is non-null and a null surfaced as a
  generic command failure on first .merged read (#5)
- dead singleColumn flag removed from the help width layout (clamp makes
  it always false; ink has no single-column mode) (#6)
- truncated SS3 tail (bare ESC O) is stripped like the truncated CSI
  tail, so a captured half F1-F4 no longer leaks 'O' into the composer (#7)
- readBufferRow trims cellColumns alongside text, so URLs ending at
  end-of-row on a wide character hit-test on both halves of the cell (#8)
- kitty probe writes guarded: a synchronous stream throw settles the
  probe (restores raw mode, removes the listener) instead of leaking (#9)
- eraseLines reuses the ansi-escapes helper (already a repo dependency)
  instead of a byte-identical hand-rolled copy (#10)
- truncateText passthrough wrapper dropped; callers use the exported
  truncateHelpText directly (#11)
- SkillsList truncate keeps total length n like ink, so the description
  column no longer shifts by one cell when a name truncates (#12)
- model_fallback names pass through sanitizeDisplayText like ink (#13)
- selectIndex fires onHighlight before onSelect (ink dispatches
  SET_ACTIVE_INDEX then SELECT_CURRENT), keeping highlight-driven
  stay-open dialogs synced on mouse input (#14)
- mcp_app without fallbackText renders empty instead of JSON-dumping the
  embedded HTML; projectAbout hides Base URL when selectedAuthType is
  empty, matching ink's formatBaseUrl (#15)

* fix(cli): drop dead single-column branch in help overlay

The foundation batch removed the always-false singleColumn flag from
the help width layout (the 72-column clamp makes it unreachable and ink
has no single-column mode); the overlay's conditional branch on it no
longer compiles. Only the two-column path was ever taken.

* fix(cli): address R3 review findings in OpenTUI foundation modules

- executeSlashCommand catch checks the abort signal first: an ESC-
  cancelled command (action rejects AbortError) returns handled with no
  failure telemetry or error message, mirroring ink's processor — the
  race promise never resolves when the signal is already aborted at
  addEventListener time
- submit effect carries the full SubmitPromptActionReturn contract
  (modelOverride, onComplete, refreshContextFilesOnWrite) so the
  backend can honor /model <id> <prompt>, /dream's manual-run record,
  and /remember's context refresh like ink instead of silently
  degrading them
- closing fences cannot carry info text (CommonMark): a ```js line
  inside an open block is literal body, not an early close that drops
  the block and inverts parse state for the rest of the document
- info items append their linkUrl/linkText footer (ink's InfoMessage
  renders it; headless/SSH users need the printed URL, e.g. /bug)
- the screen-reader sanitize keeps TAB: it separates words in
  tool/model output and deleting it fused adjacent tokens

* fix(cli): address R4 review findings in OpenTUI foundation modules

- a11y-plain-text: split on all CommonMark line endings so CRLF
  markdown opens/closes fences correctly; private-param CSI regex
  covers ECMA-48 intermediate bytes; DCS/SOS/PM/APC and unterminated
  OSC sequences consumed before strip-ansi; code-span pattern mirrors
  ink's INLINE_CODE_SPAN_PATTERN (non-empty content, closing-run
  lookbehind)
- dialogs-shared: clearNumberBuffer called from setActiveIndex,
  selectIndex, and resyncKey block so wheel/hover/click/resync can't
  commit a stale numeric-flush selection the user never made
- event-adapter: tool_call_response carries visionBridgeNotice on the
  tool-result event (ink ToolMessage renders the egress disclosure)
- item-projection: projectContextUsage reads memoryFiles as { path,
  tokens } (ContextMemoryDetail), not { name, tokens }
- key-map: 10 kp* keypad-navigation aliases (kpleft→left, …) and
  super flag folded into meta (ink Cmd+Enter = newline, not submit)
- link-click: cellColumns no longer truncated to trimmed text length
  (preserves the wide-glyph right-half boundary); findUrlAtRow end
  boundary is width-aware (stringWidth of the last glyph)
- slash-dispatch: submit effect carries PartListUnion content + a
  textContent string for text-only consumers (image parts survive);
  toggleVimEnabled and startNewSession seams wired from env; abort
  race resolves immediately for an already-aborted signal
- clipboard: OSC 52 self-write removed — copyToClipboard's existing
  fallback (writeOsc52 / wrapForMultiplexer) is the single source
- a11y-screen-reader: appendStatic skips clean === '\n' (ink's
  hasStaticOutput guard)

* fix(cli): address #10383 R1 findings in foundation modules

- event-adapter: finished branch emits retry-countdown-clear BEFORE the
  info notice so the countdown row is actually cleared (the fold only
  pops when the last item is the retry row)
- item-projection: /mcp tips now include all 5 lines ink renders (added
  OAuth auth tip and Ctrl+T toggle tip)
- link-click: wide-glyph end boundary uses the last code point (not
  UTF-16 code unit) so non-BMP emoji are measured correctly by
  stringWidth
- a11y-plain-text: CSI_SEQUENCE replaces PRIVATE_PARAM_CSI — drops the
  marker requirement so any CSI (with or without private parameter
  marker, with or without intermediate bytes) is fully consumed

* fix(cli): address #10383 R1 findings in dialogs batch

- dialogs-mcp: flatServers derived from grouped render order, not raw
  prop order, so keyboard selection matches the highlighted server
- dialogs-misc: highlightScope syncs editor selection (setSel) so Enter
  persists the highlighted scope's own editor, not the previous one
- dialogs-settings: buildSettingsListItems forwards
  excludeWorkspaceRestricted under Workspace scope, matching ink's
  filter that prevents dead settings entries
- dialogs-extensions: all onDetailAction call sites now swallow async
  rejections (.catch), matching session-rewind.tsx's pattern
- dialogs-stats-skills: metrics read from per-session bucket
  (getMetricsForSession) not process-global; Wall Time computed from
  uiTelemetryService.getSessionStartTime() not a module-load constant
- dialogs-modes: MODE_DESC key 'auto_edit' fixed to 'auto-edit' to
  match ApprovalMode.AUTO_EDIT enum value

* fix(cli): address #10383 R2 Critical findings in slash-dispatch

- abort race: already-aborted signal now skips command.action entirely
  (result = undefined) instead of eagerly evaluating it as a Promise.race
  argument — the action's side effects (clear, persist, addItem) must not
  run on a cancelled submission
- parent command telemetry: logEvent (slash_command SUCCESS) is now
  called before the early return for parent commands with subCommands
  (help listing) and bare handled — matching ink's finally-block logging

* fix(cli): address #10383 R2 Critical findings in dialogs batch

- dialog-data: buildModelEntries image mode gates on
  isImageGenerationCapable (not imageOnly) so dual-role and visionOnly
  image-capable models appear in the image selector like ink
- dialogs-extensions: detailSelect gets resyncKey: view so the cursor
  re-syncs when re-entering detail (action list shrinks after
  checked-update state resets)
- dialogs-stats-skills: subscribes to uiTelemetryService 'update' event
  so stats stay live while the dialog is open (ink re-renders via
  SessionStatsProvider)

* fix(cli): address #10383 R3 review findings in opentui dialogs/dispatch

- buildModelEntries: keep visionOnly models in the image selector (ink
  ModelDialog parity: isVisionModelMode || isImageModelMode || !visionOnly)
- useDialogSelect: re-sync the cursor on items changes like ink's
  useSelectionList INITIALIZE reducer — follow the active item's key,
  fall back to the initial index when it is gone, so a shrinking list
  never strands the cursor where Enter reads undefined
- OpenTuiSlashDispatcher: skip the action entirely when the signal is
  already aborted before the race — a late 'abort' listener never fires,
  so the eager race would run side effects before discarding
- tests: pin the pre-aborted skip in both dispatchers, the dual-role
  image/vision fixture, the items-shrink clamp, and restore the
  uninstall-backout guard assertion

* fix(cli): address #10368 R2 review findings in live-session batch

- input-prompt: convert OpenTUI display-width cursor coordinates to
  code-point positions at the component boundary — the pinned
  @opentui/core reports logicalCursor.col/offset and el.cursorOffset in
  terminal-cell units (edit-buffer.zig), while the ported ink helpers
  work in code points; wide characters previously shifted placeholder
  backspace, the backslash continuation check, completion targeting,
  and history edge compares
- input-prompt: bump both search sequence refs when Esc dismisses the
  completion dropdown so an in-flight search resolving afterwards cannot
  re-open it and hijack Enter
- live-session-model: carry the vision-bridge egress disclosure through
  the tool-result fold (ink ToolMessage renders it under the result)
- messages: recognize the producers' two-L 'cancelled' summary spelling
  so canceled tools get the CANCELED glyph with strikethrough instead of
  the red ERROR glyph
- session-switch: wrap /resume and /branch in the telemetry swap
  transaction (begin before the outgoing-session capture, commit at the
  UI re-key, abort after a rolled-back swap) — restores the usage
  aggregate on failed swaps and rejects concurrent switches
- tests: display-width fake editor, wide-char placeholder/continuation
  witnesses, Esc invalidation, fold notice, cancelled spelling, and the
  three swap-transaction lifecycle cases

* fix(cli): declare cursorOffset on the FakeEditor test interface

The display-width fake added in 656e996c9a implements a cursorOffset
getter/setter but the interface it is cast through never declared the
member, so tsc --build fails with TS2339 at the two reads in the
wide-char placeholder test. Typecheck ran before that commit's files
were staged and missed it.

* fix(cli): address #10383 R4 review findings in dialogs batch

- commands-dispatch.test: type the pre-aborted action mock as
  SlashCommandActionReturn so tsc --build passes (the inferred
  { type: string } could not satisfy the literal 'message' kind)
- dialogs-shared.test: pin the resyncKey numeric-flush disarm — an
  armed digit quick-select must not commit a selection in the view
  swapped to before the flush timeout
- session-switch.test: pin the unarmed-swap settlement when the
  resumed session is not found (commit, never abort) so the single
  swap slot cannot stay latched forever

* test(cli): stub listStartingRunIds in the session-switch fake registry

The workflow-run registry gained listStartingRunIds with the workflow
tasks feature on main; backgroundWorkUtils iterates it when describing
blocking work, so the fake registry in session-switch.test.ts now
implements it (empty) to match the interface the merged code expects.

* fix(opentui): address P2 review findings in session-rewind and load_history

- session-rewind: add useRef re-entrancy guard to prevent double onRewind
  from batched key events in single stdin chunk
- session-rewind: dispatch restore-error on onRewind rejection so the
  dialog recovers from dead 'restoring' phase back to 'pick'
- commands-dispatch: pass Date.now()-based timestamps to addItem instead
  of array indices in load_history branch

* fix(cli): address ytahdn independent review findings in OpenTUI foundation

All 15 findings from the independent static review verified in source and

- quit effect carries QuitActionReturn.messages projected to text on a

  permanently lost (Important #1)
- error and finished branches emit retry-countdown-clear like ink's

  empty, matching ink's formatBaseUrl (#15)

* fix(cli): address R3 review findings in OpenTUI foundation modules

- executeSlashCommand catch checks the abort signal first: an ESC-
  cancelled command (action rejects AbortError) returns handled with no
  failure telemetry or error message, mirroring ink's processor — the
  race promise never resolves when the signal is already aborted at
  addEventListener time
- submit effect carries the full SubmitPromptActionReturn contract
  (modelOverride, onComplete, refreshContextFilesOnWrite) so the
  backend can honor /model <id> <prompt>, /dream's manual-run record,
  and /remember's context refresh like ink instead of silently
  degrading them
- closing fences cannot carry info text (CommonMark): a ```js line
  inside an open block is literal body, not an early close that drops
  the block and inverts parse state for the rest of the document
- info items append their linkUrl/linkText footer (ink's InfoMessage
  renders it; headless/SSH users need the printed URL, e.g. /bug)

  ink's INLINE_CODE_SPAN_PATTERN (non-empty content, closing-run
  lookbehind)
- dialogs-shared: clearNumberBuffer called from setActiveIndex,
  selectIndex, and resyncKey block so wheel/hover/click/resync can't
  commit a stale numeric-flush selection the user never made
- event-adapter: tool_call_response carries visionBridgeNotice on the

- item-projection: projectContextUsage reads memoryFiles as { path,

  marker requirement so any CSI (with or without private parameter
  marker, with or without intermediate bytes) is fully consumed

* fix(cli): address #10383 R2 Critical findings in slash-dispatch

- abort race: already-aborted signal now skips command.action entirely
  (result = undefined) instead of eagerly evaluating it as a Promise.race

  run on a cancelled submission
- parent command telemetry: logEvent (slash_command SUCCESS) is now
  called before the early return for parent commands with subCommands
  (help listing) and bare handled — matching ink's finally-block logging

* fix(cli): address #10368 R2 review findings in live-session batch

- input-prompt: convert OpenTUI display-width cursor coordinates to
  code-point positions at the component boundary — the pinned
  @opentui/core reports logicalCursor.col/offset and el.cursorOffset in
  terminal-cell units (edit-buffer.zig), while the ported ink helpers
  work in code points; wide characters previously shifted placeholder
  backspace, the backslash continuation check, completion targeting,
  and history edge compares
- input-prompt: bump both search sequence refs when Esc dismisses the
  completion dropdown so an in-flight search resolving afterwards cannot
  re-open it and hijack Enter
- live-session-model: carry the vision-bridge egress disclosure through
  the tool-result fold (ink ToolMessage renders it under the result)
- messages: recognize the producers' two-L 'cancelled' summary spelling
  so canceled tools get the CANCELED glyph with strikethrough instead of
  the red ERROR glyph
- session-switch: wrap /resume and /branch in the telemetry swap
  transaction (begin before the outgoing-session capture, commit at the
  UI re-key, abort after a rolled-back swap) — restores the usage
  aggregate on failed swaps and rejects concurrent switches
- tests: display-width fake editor, wide-char placeholder/continuation
  witnesses, Esc invalidation, fold notice, cancelled spelling, and the
  three swap-transaction lifecycle cases

* fix(cli): declare cursorOffset on the FakeEditor test interface

The display-width fake added in 656e996c9a implements a cursorOffset
getter/setter but the interface it is cast through never declared the
member, so tsc --build fails with TS2339 at the two reads in the
wide-char placeholder test. Typecheck ran before that commit's files
were staged and missed it.

* test(cli): stub listStartingRunIds in the session-switch fake registry

The workflow-run registry gained listStartingRunIds with the workflow
tasks feature on main; backgroundWorkUtils iterates it when describing
blocking work, so the fake registry in session-switch.test.ts now
implements it (empty) to match the interface the merged code expects.

* fix(opentui): address yiliang114 review findings (4 P2 + 1 P3)

- transcript-adapter: FIFO queue for id-less tool call pairing so
  tool-start and tool_result share the same minted id
- session-switch: move uiSwapped=true to right after startNewSession
  (the first irreversible host mutation) preventing core/UI divergence
  on mid-sequence throw; same fix for branch handler
- session-switch: add error item when /resume targets an unloadable
  session instead of returning silently
- diff-render: run diff content through escapeAnsiCtrlCodes matching
  the ink text-boundary convention (useTurnDiffs.ts)
- package.json: move remend from devDependencies to dependencies
  (imported from production source markdown-heal.ts)

* fix(transcript): address R6 review — thinking latch, cancelled status, text join

- Replace one-shot `closed` latch with `thinkingOpen` state so
  [thought, text, thought, ...] patterns emit matching thinking-end
  for each burst (P2)
- Mirror live path: treat cancelled tool status as failed, not ok (P3)
- Join user text parts with newline instead of empty string (P3)
- Regenerate package-lock.json so remend is in dependencies (P2)

* fix(opentui): address review-pr bot R3 critical findings

- session-compaction: add missing COMPRESSION_FAILED_EMPTY_SUMMARY,
  OUTPUT_TRUNCATED, and API_ERROR cases to match ink compression-text.ts
- live-session: distinguish cancelled from error in tool-end summary
  so toolStatusMeta renders strikethrough instead of red X
- transcript-adapter: gate slash_command replay on phase=invocation to
  prevent double-replay (recorder writes both invocation and result)
- input-prompt: add key.meta/key.option to DELETE_WORD_BACKWARD branch
  to match the guard condition that intercepts Alt+Backspace

* fix(opentui): address round-5 review findings R2-5 R3-2 R3-12 R4-1

R2-5: update session-compaction.test.ts to assert the three new
parity texts (EMPTY_SUMMARY, OUTPUT_TRUNCATED, API_ERROR) added in
63a7f3c; the old assertion that EMPTY_SUMMARY returned '' is stale.

R3-2: transcript-adapter replay producer folded cancelled tool status
into summary 'error' (red ✕) instead of 'cancelled' (strikethrough).
Add the cancelled branch to match live-session.ts.

R3-12: hidden slash-command invocations (hiddenInvocation: true for
/auth, /help, /settings, /status, bare /effort, /btw) replayed as
visible user rows and entered composer history. Gate them on the
hiddenInvocation flag in the invocation filter.

R4-1: modelOverride was only carried on the first UserQuery send;
ToolResult continuation sends omitted it, so a per-turn model override
silently reverted to the session default after the first tool batch.
Propagate modelOverride into every continuation send.

ChiGao 3f71359ea8 fix(serve): classify channel initialization timeouts (#10404)
* fix(serve): classify channel initialization timeouts

* fix(serve): scope the init-timeout safe-retry contract to plain creation

The initialize-timeout mapping in sendBridgeError promised
retryable:true / sideEffectPossible:false for every route, but two
paths mutate before or around the initialize handshake:

- POST /session with branch/worktree runs createBranch (moving the
  shared HEAD) or creates a worktree before spawn, and the rollback on
  failure is best-effort — a failed checkout rollback leaves the repo
  on the new branch while the response claims no side effect.
- POST /session/:id/branch and /side-task can time out on a
  replacement channel's initialize after the fork was already durably
  committed; a contract-trusting retry would commit a duplicate fork.

The safe-retry shape is now emitted only when the caller asserts via
the new initPrecedesMutations context flag that initialization
strictly precedes every durable mutation — POST /session sets it only
when no branch/worktree was prepared. All other paths keep the typed
init_timeout code, phase, and timeoutMs but omit Retry-After,
retryable, and sideEffectPossible, reporting an unknown outcome.

The protocol doc narrows the authoritative claim accordingly and
notes that timeoutMs reflects the configured --initialize-timeout-ms
budget (values shown are the default). Tests pin the branch-body
reduced shape (red without the route guard) and the non-initialize
label falling through to the generic 500.

* docs(serve): clarify init_timeout 504 on load/resume routes

The restore Errors list previously described every 504 as
session_restore_timeout (retryable, fenced), but an init-budget
expiry during ensureChannel returns init_timeout without Retry-After,
retryable, or fence — the restore was never dispatched. Add the
init_timeout 504 entry and narrow the "any other route" paragraph
to mutation-bearing routes, explicitly calling out load/resume.

* fix(cli): remove duplicate BridgeTimeoutError import in error-response

The file imported BridgeTimeoutError from both
@qwen-code/acp-bridge/status and ../acp-session-bridge.js,
which caused a TS2300 duplicate identifier build failure.
Drop the bridge/status import; the local acp-session-bridge
re-export is the one used across the route error handling.

* fix(cli): reconcile init_timeout tests and docs with merged #10268 behavior

Update error-response and server tests plus the qwen-serve protocol doc
to reflect that `newSession` dispatch timeouts now map to a retryable
`init_timeout` 504, while `initialize` timeouts without caller context
use the reduced contract.

ChiGao be585888f8 fix(serve): add opt-in prompt-settled close grace for poll-based SSE clients (#10344)
* fix(serve): fix event_stream_resync_required for poll-based SSE clients

Two root causes were identified from production trace data:

**Root cause 1 (72% of incidents): ring_evicted**
Agentic coding sessions generate 25 000+ events per turn, exhausting
the default ring size of 8 000. When the ring fills, the oldest events
are evicted and a reconnecting client receives `ring_evicted`, forcing
a full resync. Raise `DEFAULT_RING_SIZE` from 8 000 to 32 000 to
provide adequate headroom (~1–2 MB RAM per session at typical event
sizes).

**Root cause 2 (13% of incidents): epoch_reset / session_rebuilt**
Poll-based SSE clients (e.g. DataAgent CLI) disconnect for up to 12 s
between polls. When the last client detaches immediately after a prompt
settles, the daemon closes the session through `last_client_detached`.
The next poll reconnects, restores a new session with a fresh EventBus
epoch, and the old `Last-Event-ID` becomes invalid, triggering resync.

Add `sessionPromptSettledCloseGraceMs` (default 0, preserving existing
behavior for all library consumers). When set > 0, a deferred timer
replaces the immediate `last_client_detached` close after a prompt
result. A reconnecting poll client calls `subscribeEvents`, which clears
the timer and keeps the session alive. Web clients with persistent SSE
connections are completely unaffected — their `clientIds.size` stays > 0
so `entryIsAutoCloseCandidate` never fires.

`qwen serve` exposes `--session-prompt-settled-close-grace-ms` to let
operators tune the window. The DataAgent CLI sets 60 000 ms (60 s) to
comfortably cover its 12 s poll gap with margin.

Fixes: ring_evicted and epoch_reset resync incidents for CLI polling
clients. No behavior change for default-config or web shell deployments.

* fix(serve): address review criticals — timer overwrite and grace-hold consumed on first reconnect

R1-1: schedulePromptSettledClose now clears any pending timer before arming a
new one, so two prompt settles inside one grace window no longer leak the first
timer and close the session at the first settle's deadline.

R1-3: subscribeEvents now calls cancelPromptSettledTimer (timer only) instead
of clearPromptSettledClose (timer + stamp), so the promptSettledAt hold in
entryIsAutoCloseCandidate survives the subscribe → drain → detach cycle.
detachClient calls rearmPromptSettledClose after maybeCloseIdleSession to
reschedule the close for the remaining grace window once the last subscriber
drops.

Also fixes two doc mismatches in bridgeOptions.ts: removes the false claim
that qwen serve sets 60_000 (the default is 0, it is opt-in via flag) and
corrects the scope note — the hold gates every automatic close path, not just
prompt_settled.

* fix(serve): narrow PR to prompt-settled grace and revert default ring-size bump

Per review feedback, scope the change to the opt-in prompt-settled close
grace window and its lifecycle edge cases:

- Revert the global DEFAULT_RING_SIZE change from 32,000 back to 8,000;
  keep only the --event-ring-size option for operators who need it.
- Fix deferred-close handling around subscribeEvents, detachClient,
  closeSession, and killSession so the grace window survives reconnect
  churn and refused closes without orphaning timers.
- Add DAEMON-005 regression tests for the above lifecycle edge cases.
- Expose sessionPromptSettledCloseGraceMs in SDK daemon-status types and
  document the new CLI flag.

Refs: #10344

* fix(cli): tolerate yargs line wrap when checking IPv4 help text

The new --session-prompt-settled-close-grace-ms flag widens yargs' option
column, causing the --hostname description to wrap 127.0.0.0/8 across lines.
Strip whitespace before the substring assertion so the test stays robust.

The daemon JSON-RPC error-detail surfacing grew the browser-safe

ChiGao ec2fc5dd23 feat(cli): OpenTUI migration foundation batch — theme, a11y, clipboard, keys, dialogs scaffolding (#10146)
* feat(cli): OpenTUI foundation modules — theme, a11y, clipboard, keys, dialogs scaffolding

Foundation batch of the OpenTUI migration tracked in #8662. Adds the renderer-neutral foundation modules under ui/opentui: theme family, a11y (plain-text, screen-reader), clipboard, key-map, mouse hit/caret, link-click + osc8 parity, early-input, exit guard/lifecycle, kitty negotiation, event-adapter, item-projection, slash dispatch (+ command parsing), commands context/output, help content, input history, and the dialog scaffolding primitives (core/shared) with the theme dialog. Two helpers land inside ui/opentui rather than utils/ to respect the utils leaf-layer rule (#9737). Stacked on the infra batch: consumes ui/model streaming model and @opentui deps. No reachable ink code changes beyond a one-line export addition in the shared osc8 module.

* fix(cli): import originals instead of forking slash parser and dialog scope utils

* fix(cli): address R1 review findings in OpenTUI foundation modules

* fix(cli): align OpenTUI command host with the memory-file-count rename

Upstream renamed setGeminiMdFileCount to setMemoryFileCount in the command
UI contract; the rebase onto main surfaced the mismatch at build. Rename
the host interface member, the bridge wiring, the dispatch stub, and the
test mock to match.

* fix(cli): address R2 review findings in OpenTUI foundation modules

Round-2 review fixes (17 Critical + 10 Suggestion resolved in code):

- dialogs-shared: move number-select flush out of the setState updater
  (StrictMode double-fires onSelect); split setActiveIndex (ink
  SET_ACTIVE_INDEX, lands on any in-range row) from highlightIndex
  (arrow keys skip disabled rows) so wheel navigation never sticks
- event-adapter: chat_compressed notice mirrors ink formatCount ('~'
  prefix for estimated counts); vision_bridge_notice renders
  summary\nnotice; explicit projections for task_execution /
  findings_list / terminal_image keep multi-MB payloads off the
  transcript; retry-countdown-clear forwards isContinuation
- slash-dispatch: isSlashCommandInput drops the '?' branch (ink gate
  routes ? input to the model); executeSlashCommand races the action
  against the abort signal; dialog effects carry the
  OpenDialogActionReturn payload; projected added-item text surfaces
  alongside non-handled effects (notice); message-shaped items project
  to their text; ui.history comes from env; absent sessionStats stamp
  now, not epoch; telemetry parity (recordSkillInvocation /
  recordAutoSkillCommandUsage / makeSlashCommandEvent)
- item-projection: model stats render per-(model,source) sections with
  N/A for unpriced entries; Tool Calls line uses ASCII x like ink;
  redactProxy deduplicated via systemInfoFields export
- theme: palette/syntax colors resolve through color-utils toHex before
  parseColor (ink CSS names / *bright names no longer degrade to
  magenta); unresolvable values stay unset
- key-map: kitty 'kpenter' normalizes to 'return'; resolveCommands
  exposes ink's key fan-out (Ctrl+C fires QUIT + CLEAR_INPUT)
- a11y: hardWrap delegates to wrap-ansi (word-boundary parity with
  ink's screen-reader path); markdown reducer tracks fence length,
  keeps fence-like lines literal inside fences and inner backticks in
  multi-backtick spans; stripAnsi delegates to strip-ansi plus a
  private-parameter CSI pass (SGR mouse, DEC save/restore)
- clipboard: OSC 52 write gated on a TTY (stderr preferred), tests spy
  the stream instead of writing real sequences to the runner's terminal
- exit-guard: independent per-key arm windows like ink
- dialogs-theme: diff preview pane receives syntaxStyle/filetype

* fix(cli): harden kitty probe and screen-reader writer per maintainer review

- kitty-negotiation: KITTY_REPLY_RE requires at least one flag digit
  (\d+), so an echoed bare query \x1b[?u in PTY/CI environments no
  longer resolves true and locks the renderer into kitty mode on a
  terminal that never answers queries; the accumulation buffer keeps
  only a 256-byte tail (bounded memory, bounded rescan under byte
  floods); the settle-window drain is removed — an EventEmitter data
  listener cannot consume chunks from other listeners, so late replies
  flow to the renderer's input parser like any other terminal noise
- a11y-screen-reader: ScreenReaderOutputWriter sanitizes written
  content (stripAnsi + drop bare C0/C1 controls, keep newlines) so the
  plain-text-only contract is enforced at the writer instead of
  trusting every future caller — smuggled OSC 52 clipboard writes or
  title/cursor sequences cannot execute on the main screen

* fix(cli): address ytahdn independent review findings in OpenTUI foundation

All 15 findings from the independent static review verified in source and
fixed (no false positives; none deferred):

- quit effect carries QuitActionReturn.messages projected to text on a
  notice field — ink renders them via QuittingDisplay and the payload was
  permanently lost (Important #1)
- error and finished branches emit retry-countdown-clear like ink's
  handleErrorEvent/handleFinishedEvent, so a terminal event inside the
  countdown window no longer leaves a stale retry row (#2)
- projectContextUsage renders the compaction-threshold ladder and the
  per-item detail sections (tools/memory/skills, ink's sort order) when
  showDetails is on — /context detail transcripts no longer show strictly
  less than the compact view (#3)
- projectMcpStatus honors showSchema (parameter JSON under each tool) and
  showTips, so /mcp schema is distinguishable from /mcp (#4)
- SlashDispatchEnv.settings is required: the real
  CommandContext.services.settings is non-null and a null surfaced as a
  generic command failure on first .merged read (#5)
- dead singleColumn flag removed from the help width layout (clamp makes
  it always false; ink has no single-column mode) (#6)
- truncated SS3 tail (bare ESC O) is stripped like the truncated CSI
  tail, so a captured half F1-F4 no longer leaks 'O' into the composer (#7)
- readBufferRow trims cellColumns alongside text, so URLs ending at
  end-of-row on a wide character hit-test on both halves of the cell (#8)
- kitty probe writes guarded: a synchronous stream throw settles the
  probe (restores raw mode, removes the listener) instead of leaking (#9)
- eraseLines reuses the ansi-escapes helper (already a repo dependency)
  instead of a byte-identical hand-rolled copy (#10)

  truncateHelpText directly (#11)
- SkillsList truncate keeps total length n like ink, so the description

* docs(design): publish the OpenTUI migration design and architecture notes

Reference document for the batched TUI migration (#8662), requested in the
maintainer direction call: motivation and measurements, the dependency-
direction invariant and its CI gate, the layering from streaming model to
renderer dispatch, the seven-batch landing plan with acceptance criteria,
the rollout phases with explicit flip gates, and the tracked deferrals.

* docs(design): stats is a derived output field, not a StreamEvent member

The streaming-model section listed stats among the folded input events,
but the landed StreamEvent union has no stats member — task-end derives
the stats line as an output field on the task history item. Rephrased so
readers grepping for a stats event find the actual shape.

Infra batch of the OpenTUI migration tracked in #8662. Versions are pinned (not ranged) so renderer behavior stays reproducible across the landing batches.

* feat(cli): add dependency-direction arch check and framework-neutral streaming model

Infra batch of the OpenTUI migration tracked in #8662.

* fix(repo): cover import-type/template-literal specifiers and contain symlink traversal in dep-direction gate

- findImports now handles ImportTypeNode (type X = import("...").Y) and accepts interpolation-free template literals as specifiers for import()/require()/vi.mock(), so every statically knowable module specifier is classified; interpolated templates stay skipped.

- listSourceFiles resolves each symlink target against the physical rule root and reports escaped links as gate failures, so traversal cannot leave the root and relative imports cannot be masked by lexical symlink paths.

* fix(repo): fail the dep-direction gate closed on any symlink

A symlink's bytes live wherever the link points, but the gate resolves a
file's relative imports from the path it was reached at. Following links
therefore desyncs lexical resolution from physical location and can report
an escape that physically stays in the rule root, or pass an import that
physically escapes — the latter reproduced end-to-end on the prior head via
a link into a skipped dist directory. Neither direction is auditable
link-by-link, and the tree commits no symlinks, so the walker now reports
any symlink and fails the gate instead of following it. This also removes
the relative()-based containment predicate, which accepted cross-volume
absolute results on Windows.

* fix(repo): reject symlinked rule-root paths in the dep-direction gate

readdirSync follows a symlink transparently, so a rule root that is itself
a link — or whose ancestor components are — let a commit substitute the
protected scan with a clean tree elsewhere while the configured path read
unchanged and no in-tree symlink diagnostic fired (both forms reproduced:
swapping packages/cli/src/ui/model for a link exited 0, as did swapping the
ui ancestor). Every path component below the repo root is now lstat-checked
before enumeration and any symlink fails the gate.

* fix(repo): classify import-equals and resolution probes in dep-direction gate

Self-audit found three statically knowable framework-reference forms the
AST walk skipped: import-equals (`import x = require("ink")`, with or
without the export modifier), `require.resolve("ink")`, and
`import.meta.resolve("ink")` — the latter two name a framework package
even though they never load it. All three are now classified with probe
tests; the namespace form of import-equals (no module specifier) stays
ignored. The dynamic-import operator aliasing limitation (`const i =
import; i("...")`) is documented in the detector contract rather than
silently left open.

* test(repo): end-to-end the dep-direction gate's main wiring

Mutation audit found the main() wiring unguarded: removing the root-path
symlink check, the in-tree symlink failure loop, the violation aggregation,
or the populated-root guard left every unit test green while a manual probe
showed the bypass re-opening. Six subprocess tests now run the real script
against a fixture checkout (clean tree, symlinked rule root, symlinked
ancestor, banned import, in-tree symlink, empty rule root) and assert exit
codes and diagnostics; each of those four deletions now fails the suite.

* fix(repo): validate rule-root paths before enumerating in dep-direction gate

The root-path symlink check ran after requirePopulatedRoot() had already
walked both roots, so a symlinked rule root pointed at an external
directory got its files read and parsed before the link was diagnosed,
and an empty external target exited through the populated-root guard
without ever reaching the symlink diagnostic. Reject any link in the
rule-root path components before enumeration and exit immediately. The
end-to-end fixture tests now assert the redirected target is never
scanned (a banned import in the substitute stays out of the output) and
that an empty substitute reports the symlink error, not the empty-root
error.

* fix(repo): harden dep-direction gate per round-2 review findings

- Rule 1 now blocks bare imports of the cli package's own name (read from
  its manifest so a rename cannot decouple the check): the workspace
  symlink makes `import ... from '@qwen-code/qwen-code'` resolve from
  core, which is exactly the core->cli reach the rule forbids.
- Classify the remaining statically knowable forms: the vi module-loading
  family (mock/doMock/importActual/importMock), module.require,
  require.main.require, and ambient module declarations.
- Fail closed on skipped-directory names (node_modules/dist/.git) inside a
  protected root instead of silently shrinking the scan.
- Replace process.exit(1) with process.exitCode + natural unwind so
  buffered diagnostics flush to CI pipes before termination.
- Add the missing witnesses: noRelativeIntoCli relative and bare arms, the
  ui/model rule arm (both messages), the core-root symlink arm, the empty
  ui/model arm, a .js extension fixture, an unlistable-directory e2e case,
  the skippable-directory case, @solid/ and @react-* table rows, and the
  entry-guard import-suppression side.

* fix(cli): reset items on replayed stream starts and pin rewrite branches

A retry/reconnect can re-emit a tool-start or task-start whose id already
exists; the unconditional push created a duplicate that later events (which
match the first id hit) left stranded at done:false forever. Reset the
existing item instead. Also extend the fold immutability matrix with the
two rewrite branches it did not exercise (closeTrailingAssistant via
text->tool-start and text->done, and the thinking-end rewrite), so an
in-place mutation in either branch now turns the suite red.

ChiGao 6d036aed41 fix(cli): bound the goal-runtime startup wait and skip the no-op Bun memory relaunch (#10128)
* fix(cli): bound the goal-runtime startup wait so lease contention cannot hang the TUI

* fix(cli): skip the no-op memory-flag relaunch under Bun

Bun accepts --max-old-space-size but ignores it (its heap limit adapts dynamically), so the autoConfigureMemory relaunch only wastes a process hop under Bun.

* fix(cli): surface goal-runtime degraded startup and fix Bun comment framing

- Route the goal-runtime startup timeout through mergeStartupWarnings so
  users see why goal features are degraded without QWEN_CODE_DEBUG=1.
- Reword the Bun memory-flag comment: the one-process relaunch is
  unconditional, so the guard only stops forwarding a no-op V8 flag into
  the relaunch/sandbox child.

ChiGaoand秦奇 02d303f849 feat(serve): persist prompt terminal ledger for cold-load reconciliation (#9426)
* feat(serve): persist prompt terminal ledger for cold-load reconciliation

Turn terminal events (turn_complete / turn_error) were synthesized by the ACP bridge and published over SSE only, so a prompt that was in flight when the daemon died could never be resolved after a restart: the cold load replay emits transcript chunks and carries no terminal evidence, leaving promptId-keyed orchestrators stuck on "unknown".

Each session now owns an append-only sidecar ledger next to its transcript. The bridge appends one in_flight record at prompt admission and one terminal record at the single publishPromptTerminal exit (covering the close/kill/channel-crash/daemon-shutdown flushes) through an injected synchronous sink. Ledger writes are best-effort and never block prompt execution or teardown, and records carry only ids, states, and timestamps — no prompt text, user content, or paths.

On a cold session load the serve layer reconciles prompts left dangling by a dead daemon: it classifies the transcript tail with the existing turn-interruption detector and appends a completed (stop reason reconstructed_from_transcript) or interrupted (code daemon_lost) verdict, guarded by an attribution check so an unattributable tail stays unknown (fail-closed). The load response gains an optional promptTerminals field with the trailing 64 terminal records, omitted entirely when the ledger holds no terminal evidence, and archive/unarchive move the sidecar alongside the transcript so evidence survives storage lifecycle.

Design: docs/design/2026-08-19-prompt-terminal-ledger-design.md

* fix(serve): tighten ledger reconciliation fail-closed semantics and complete sidecar lifecycle

Address review findings on the prompt terminal ledger:

- reconcile: fail closed on multiple dangling prompts (no synthesized
  terminal for the newest either); attribute the oldest dangling prompt
  only when the attribution guard skips settled admissions (fixes the
  [A if, B if, B cancelled] misattribution veto), the transcript's last
  write postdates the admission (temporal evidence), and a clean
  verdict is upgraded to interrupted when the model tail holds any
  functionCall part, id or not (id-less tool-call guard covering the
  detectTurnInterruption wire-pairing blind spot)
- lifecycle: removeSessionFiles deletes the ledger in both archive
  states; archive/unarchive move it through a single
  getPromptLedgerPathForState helper with merge semantics when the
  destination already exists (append-and-unlink instead of a permanent
  split); move warnings carry full source and destination paths in
  both directions
- scans: DataProcessor.scanChatFiles and
  usageHistoryService.rebuildFromSessionJsonl exclude .ledger.jsonl
  sidecars (the ledger is not a transcript)
- writer: appendPromptLedgerRecord seals a torn tail before appending
  so a torn fragment cannot fuse with (and destroy) the next record
- tests: pin the new behavior across multi-dangling fail-closed,
  settled-then-queued attribution, valid interleave migration,
  temporal veto, id-less tool-call guard, sidecar lifecycle
  (move/merge/warn-only delete), torn-tail sealing, queued-admission
  flush on shutdown, active-prompt and resume load contracts, and
  ledger exclusion from insight scans
- docs: sync the design doc's reconciliation algorithm, lifecycle, and
  fail-closed invariants

* perf(serve): read only the ledger tail for load-response promptTerminals

readRecentPromptTerminals ran on every POST /session/:id/load (including
attached hot loads) and synchronously read and JSON-parsed the entire
ledger — a multi-megabyte event-loop stall for long sessions on the
per-request hot path.

Add a tailBytes option to readPromptLedgerRecords that reads a trailing
byte window (the first window line is always dropped: the window start
can tear a line in half). The load path now reads a 256 KiB window,
which holds hundreds of ~150-byte records against the 64-terminal
response cap; sessions whose ledger outgrows the window return a
best-effort trailing subset, which the response contract already allows.

* fix(serve): close wrong-terminal attribution classes in cold-load reconciliation

Strengthen the reconcile attribution evidence per review round 2:
measure the temporal evidence on the same api-history projection the
verdict uses, fail closed on a compression checkpoint written after the
target's admission, and require the visible tail to postdate every other
prompt's settled terminal (FIFO evidence). Also fix a TS18048 narrowing
gap in the window test, make the seal test assert the raw file layout,
and restructure the window test so the call-site tailBytes wiring is
actually observable.

* fix(serve): keep ChatRecord import inline so lint-staged cannot merge it into a type-only import

* fix(serve): fail-closed reconciliation on millisecond clock equality and deadline-overlapped turns

* fix(serve): TOCTOU fence before ledger append and documented residual attribution risk

* test(serve): pin the ledger race fixture on the transcript timeline

* feat(serve): bind cold-load evidence to the admission via a dispatch marker

* test(core): pin the ledger sidecar exclusion in usage rebuild

* fix(serve): create ledger sidecar owner-only and fence marker-era compression by position

Round-7 review Criticals:
- appendPromptLedgerRecord created the sidecar with umask-default
  permissions (0o644) while the adjacent transcript is owner-only; the
  ledger now follows the 0o600 convention at creation time.
- Marker-bearing admissions fence post-admission compression by marker
  position instead of wall clock, so a backward clock step cannot hide
  a compression reset that voids the evidence chain.
- Design doc: the residual-risk claim is corrected — the dispatch
  marker binds ordering, not ownership; the two ownership classes that
  survive it (recordless predecessor with continued writes, ledger-less
  cross-client writer) are documented, pending writer identity on
  transcript records (#9483).

ChiGaoand秦奇 d96f264de7 feat(telemetry): link daemon HTTP request spans to inbound W3C traceparent (#9391)
* feat(telemetry): link daemon HTTP request spans to inbound W3C traceparent

The daemon HTTP surface records a request span per request, but every span
starts a new trace: a caller forwarding the standard W3C traceparent header
(OTel-instrumented clients, proxies, gateways) gets no linkage back to its
own trace.

Extract traceparent/tracestate from inbound request headers in the daemon
telemetry middleware and parent the request span to that remote context.
Extraction reuses the same path as the existing JSON-RPC _meta extraction
(global propagator first, strict manual fallback so behavior is identical
without a registered SDK) and fails closed: requests without a valid header
keep the exact current span shape.

* fix(telemetry): guard inbound traceparent sampling and align W3C fallback

- Force TraceFlags.SAMPLED on inbound HTTP parents via the existing
  shouldForceSampled() matrix: an unsampled remote parent under the
  default parentbased_always_on sampler silently dropped the request
  span, the whole next() subtree, and the session-subprocess spans
  forwarded via _meta (review C1).
- Replace the hand-rolled manual fallback parser with a direct
  W3CTraceContextPropagator instance so acceptance rules (future
  versions, tracestate, all-zero ids, version-00 extension field)
  match the registered path with or without an initialized SDK.
- Gate middleware extraction behind isTelemetrySdkInitialized() to
  skip the hot-path parse when telemetry is off, and emit a debug
  daemon log when a present-but-invalid traceparent header is
  rejected.
- Re-export DaemonRequestSpanOptions from the core barrel and add a
  type-level guard so the parentContext field cannot silently
  disappear (vitest alone cannot catch its removal).

* chore(vscode): regenerate companion NOTICES.txt for @opentelemetry/core

* fix(telemetry): lazy-load OTel core fallback propagator behind SDK init

Address review feedback on the inbound traceparent linkage:

- Keep @opentelemetry/core out of the static graph. The module-level
  W3CTraceContextPropagator in daemon-tracing.ts pulled the CJS barrel
  (bot-measured +65,046 bytes) into every closure loading that module,
  including telemetry-off deployments. daemon-tracing.ts now keeps only a
  holder + setter (setDaemonFallbackPropagator, typed against
  @opentelemetry/api — type imports stay free at runtime); the lazy
  sdk-impl.ts chunk, whose closure already contains @opentelemetry/core via
  sdk-node/resources, constructs and injects the W3C instance on the
  successful SDK assembly path. Until injection, extraction returns no
  parent context: the HTTP edge is already gated on
  isTelemetrySdkInitialized (nothing changes when telemetry is off), and
  the _meta edge's consumers (withDaemonSpan / withInteractionSpan)
  short-circuit on the same flag, so an unresolved pre-init parent never
  had an observable effect.
- Add the mutation-verified fail-closed test for the header-extraction
  try/catch in daemonTelemetryMiddleware: a throwing extractor leaves the
  request settling normally (recordDaemonHttpRequest still fires once)
  with no parentContext on the span options.
- Record the rejected traceparent value (truncated to 128 chars) as
  http.request.header.traceparent on the invalid-header breadcrumb —
  traceparent only carries trace-id/span-id/flags, so this is
  privacy-safe and makes broken cross-service joins diagnosable.

Also document why the _meta extraction path deliberately skips
shouldForceSampled (trusted in-process bridge vs external HTTP input).

* feat(telemetry): carry inbound trace id into daemon access log with telemetry off

Telemetry off (the default) left daemon logs without any trace id: with no
request span, the log trace prefix never fires, so a caller forwarding W3C
traceparent could not be joined to its daemon log lines.

The middleware now parses the header with a plain regex
(extractInboundTraceId — same shape/all-zero/ff rejections as the W3C
propagator, no OTel machinery) and stores the trace id on the per-response
telemetry context. The access log emits it as the camelCase traceId field
of "request completed", keeping the log-based join alive with no telemetry
config and no trace backend. With telemetry on nothing changes: the request
span already carries the caller's trace id into the log prefix.

* fix(telemetry): unify _meta/HTTP sampling and repair build export

- Export extractInboundTraceId from the core barrel: the previous commit
  exported it from daemon-tracing.ts only, so downstream package builds
  failed with TS2305.
- extractDaemonTraceContext now applies the same shouldForceSampled()
  matrix as the HTTP edge: the _meta path is also reachable from direct
  ACP clients (acpAgent newSession/loadSession/unstable_resumeSession
  and Session.prompt pass caller-controlled _meta), so an external
  sampled=0 parent no longer silences daemon spans there either. The
  in-process bridge is unaffected (its injected values are already
  SAMPLED).
- The rejected-header breadcrumb now goes through sanitizeLogText so a
  crafted traceparent cannot forge log line structure with control
  characters.
- Add the sdk-impl wiring test: after initializeTelemetry the injected
  W3C fallback propagator resolves inbound HTTP parents.

* fix(telemetry): align log-path traceparent parsing and emit traceId in both modes

- extractInboundTraceId now mirrors the vendored W3C propagator's
  acceptance exactly: single optional leading/trailing whitespace and
  trailing extension fields above version 00 (version 00 must stay
  four fields). Previously the strict four-field anchor made the two
  paths disagree on the same forward-compatible header, silently
  dropping the access-log traceId for exactly the callers the
  propagator path supports.
- The camelCase traceId access-log field is now captured whenever a
  valid header parses, regardless of telemetry mode, so one saved log
  query / alert shape works for every deployment; with telemetry on the
  snake_case span prefix carries the same id redundantly.

* fix(telemetry): move inbound trace id getter out of the middleware module

52d572c0f2 made the access log statically import the telemetry
middleware module to read the captured inbound trace id. The access log
sits inside the serve fast-path pre-listen closure (run-qwen-serve
imports it directly), so the middleware's core-barrel import graph came
along for the ride and check-serve-fast-path-bundle started failing:
the 5.6MB core chunk (shell tool, glob, chokidar, @iarna/toml, fzf)
became statically reachable from run-qwen-serve.

Move the response-context symbol, its type, and the
getDaemonTelemetryInboundTraceId getter into a new import-light
telemetry-context.ts; the middleware imports the symbol from there and
re-exports the getter, so the access log no longer links against the
telemetry module at all.

* fix(telemetry): capture inbound trace id pre-auth under a dedicated symbol

* test(telemetry): pin the trace id seam through the context module getter

5935dcfaf6 fix(cli): eliminate banner duplication and drag flicker on resize/wake (#8831)
* fix(cli): clear the VP viewport on wake/SIGCONT repaints

useWakeRepaint (#7265) repaints via refreshStatic after sleep/wake or
SIGCONT, but in VP mode (default) refreshStatic neither cleared the screen
nor repainted anything (<Static> is not rendered in VP), so Ink's next
relative erase ran against a stale/rearranged terminal buffer: frame-top
residue (banner), frame-height jumps and high-frequency flicker on every
terminal. Blank the alternate-screen viewport (2J+H, no 3J so scrollback /
Warp block history survives) before the remount-driven repaint; static mode
keeps its existing clearTerminal.

Co-authored-by: Qwen-Coder <[email protected]>

* fix(cli): repaint VP from a clean viewport after width shrinks

On shrink the terminal reflows the printed frame into more physical rows
than Ink's stale eraseLines count, so every subsequent redraw under-erases
and strands the frame top (banner) as stacked duplicates on all terminals
(issue #8557). For a short window after a shrink, start each VP redraw from
a clean viewport (2J+H); Static mode keeps a conservative reflow-aware
amplification so committed scrollback is never touched.

* fix(cli): enable DEC synchronized output on Warp to reduce redraw flicker

Warp answers the DECRQM 2026 probe with status 2 (recognized, reset), so
synchronized updates are available there. Without them Warp renders ink's
erase-then-rewrite frame pattern as visible flicker (issue #8557). Add
WarpTerminal to the synchronized-output allowlist; the existing
QWEN_CODE_DISABLE_SYNCHRONIZED_OUTPUT escape hatch covers regressions.

* fix(cli): guarantee VP wake repaint by replaying the last frame

Ink skips redraws whose output is unchanged, so the VP wake/SIGCONT path's
viewport clear could leave the screen blank until the next state change
(review #8831). The resize-reflow wrapper now caches the last frame that
reached the terminal and repaint() replays it over a clean viewport; the
stale design-rationale comment is rewritten to match.

* fix(cli): address #8831 review — LIFO teardown, grow reset, bare-redraw model handoff, wake-only repaint

- Unwind the stdout.write wrapper stack in LIFO order so the identity-
  guarded restores do not leak wrappers (Critical).
- Reset a pending static-mode amplification on grow so a stale count can
  never over-erase into committed scrollback (Critical).
- Hand the frame model over to Ink's bare post-shrink redraw (log.clear
  resets its counter, so the redraw carries no erase prefix); consecutive
  shrinks now amplify from the actual post-shrink frame (Critical).
- repaint() skips the replay when the cached frame's width differs from the
  current viewport (Critical).
- Route the clear-and-replay through useWakeRepaint only; refreshStatic's VP
  branch stays write-free for ordinary callers (/clear, model change, ...)
  so stale frames never flash back (Critical).
- Use ansi-escapes exports instead of hand-rolled ANSI constants; drop the
  duplicated WarpTerminal test row; add tests for the grow reset, the bare-
  redraw handoff, the MIN_FRAME_LINES guard and the clear-window expiry.

* fix(cli): address #8831 R3 review — model fidelity and wake remount

- Frame model now lazy and terminal-faithful: per-character greedy packing
  (wide chars waste a row-tail cell), physical-row segmentation on shrink
  (terminals re-wrap rows without re-joining), and Ink's cursor-below line
  included for frames ending with a newline (R3-3, R3-4, R3-5, R3-9).
- expectFrame handoff survives Ink's real write sequence: standalone
  synchronized-output control writes no longer consume it, and consecutive
  bare writes re-model with last-wins so static commits model the live
  frame, not the transcript (R3-1, R3-14).
- VP wake path bumps historyRemountKey again so one-shot <Static> history
  (agent tabs) is re-emitted over the clear; selection extracted into
  buildWakeRepaint for unit coverage (R3-2, R2-8).
- Shared erase grammar helpers exported from terminalRedrawOptimizer
  (R3-13); tests added for the escape hatch, repaint fallbacks, BSU
  sequences, static commits, trailing newlines and CJK packing
  (R3-10, R3-11, R3-12).

* fix(cli): address #8831 R3 review — raw-repack reflow model, wake remount bump, hardened frame handoff

* fix(cli): address #8831 R4 review — stripped-width model, legacy wake write-free, untrusted anchors, full-reset resets

- Model widths from ANSI-stripped content (SGR bytes are not cells) while
  repaint replays the raw styled frame.
- QWEN_CODE_LEGACY_RESIZE_ERASE VP wake stays write-free (remount bump only)
  instead of blanking via a bare viewport clear.
- Erase-prefixed printable writes re-model unconditionally (live region can
  legitimately shrink below MIN_FRAME_LINES); bare full-reset redraws
  (clearTerminal + full static history) reset the model instead of poisoning
  it; second printable bare write (live frame after static append) bypasses
  the line-count guard.
- Skip amplification when the return-to-bottom prefix carries cursorDown
  computed from pre-reflow geometry (untrusted anchor).
- Tests for all R4 scenarios plus wrapper-stack contracts (stacked install
  order, LIFO teardown) and the AppContainer wake wiring.

b9be6c8ee8 fix(cli): echo resume command to main screen on exit (#8455)
* fix(cli): echo resume command to main screen on exit

The quit screen already shows a resume hint, but in VP mode (the
default) it is drawn on the alternate screen, which is discarded on
teardown — users never see it. Echo the command again after Ink
unmounts, when we are back on the main screen buffer, so it survives
exit and can be copied from the terminal scrollback. Only printed when
chat recording is enabled and the session file exists, so empty
sessions do not advertise a resume that has nothing to restore.

* docs(cli): add real-machine screenshots for exit resume echo

* fix(cli): make exit resume echo best-effort and sanitize session ID

* fix(cli): make exit resume echo tests Windows-safe and pin gates

The sanitization test created a real file with ESC/BEL control bytes
in its name; Win32 forbids 0x01-0x1F in file names, so the test would
fail in the merge-queue Windows job. Stub the existence gate instead.

Also rebuild the recording-disabled negative test on a full recording
config so removing the getChatRecordingService() gate actually fails
it (it previously passed via the exception path), and add coverage for
the isTTY half of the gate. The source switches to a namespace fs
import so the gate is stubbable in vitest (trustedFolders.ts
precedent); runtime behavior is unchanged.

* fix(cli): gate exit resume echo to paste-safe session IDs

* fix(cli): reject dash-leading IDs in exit resume echo (#8455)

A dash-leading session ID (loadable from disk: SESSION_FILE_PATTERN
accepts dash-leading transcript names) pasted back as `qwen --resume
-<id>` reparses as CLI flags instead of the option value, so require an
alphanumeric first character in the paste-safe gate. Also switch the
echo to writeStdoutLine, the helper the file already imports
writeStderrLine from.

* fix(cli): gate exit resume echo to canonical session IDs (#8455)

Replace the inline charset gate with isValidSessionId, the same
canonical predicate --resume routing, --session-id validation, and the
in-TUI /resume command use. The old gate was strictly looser, so a
transcript-sourced ID (e.g. via --continue) could be echoed as a hint
that --resume then misroutes to title matching. The UUID shape is
already paste-safe, making the extra sanitizeTerminalText wrap
redundant.

Also make the positive echo test locale-independent: earlier main()
tests run the real initializeI18n('auto') and leave the machine
locale's dictionary in the i18n module state, so the hardcoded
English label failed deterministically under any supported non-English
locale. Match the locale-free command part instead, and switch the
echo test fixtures to valid UUIDs so each negative test isolates its
intended gate.

* fix(cli): align exit resume echo with --resume transcript semantics (#8455)

The echo gated on fs.existsSync(sessionFile), but --resume refuses an
empty transcript: ChatRecordingService creates the JSONL file before
the first record lands, and a failed first write (or an exit that races
the flush ceiling) leaves it empty through exit, so the hinted
`qwen --resume <id>` fails with "No saved session found with ID".
Require a non-empty transcript instead of switching to
SessionService.sessionExists(): that check's SESSION_FILE_PATTERN
rejects the -agent- suffixed Arena IDs that --resume itself accepts,
which would have silently narrowed the echo's acceptance surface.

Also mirror the full SESSION_ID_REGEX — including the -agent- suffix
form — in the gemini.test.tsx isValidSessionId mock, which had drifted
narrower than the production gate, and cover the agent-suffixed shape
with a positive echo case. The now-unused node:fs existsSync mock and
its stub in the hostile-ID cases are removed: the ID gate rejects
before any file probe.

* test(cli): Harden exit resume echo gate tests (#8455)

* fix(cli): Use async stat in exit resume echo gate (#8455)

The exit-cleanup chain bounds each cleanup with a 2s withTimeout race
and a 5s overall ceiling, but fs.statSync() blocks the event loop, so
an unresponsive filesystem (dead NFS/FUSE mount) hangs exit past both
ceilings despite the surrounding try/catch. Switch to fs/promises
stat — the handler is already async, so the existing race bounds it.

c617405a20 fix(cli): report zero-height VP items so collapsed thoughts release reserved space (#8570)
* fix(cli): report zero-height VP items so collapsed thoughts release reserved space

Collapsed thought continuations render nothing (height 0). The
`height > 0` reporting guard skipped them, so the cached expanded
height kept inflating totalHeight and the virtual viewport left a
large blank gap below the collapsed thought line. Report measured
heights once measured, including zero, and cover the expand→collapse
transition with a regression test.

* test(cli): add end-to-end regression tests for VP collapsed-thought blank gap

* test(cli): tighten collapsed-thought regression assertion (#8570)

Replace the `<= 2` slack with exact adjacency (`toBe(1)`) so a
height-clamping mutant (reporting max(1, height)) cannot pass, and a
missing FOOTER sentinel can no longer pass vacuously via findIndex -1.
Add the re-expand round trip so a cached 0 can never get stuck, drop a
redundant rerender, and document the in-window-only height reporting
caveat at the fix site.

* fix(cli): heal zero-height runs at the VP window top (#8570)

Cached zero heights (newly possible via zero-height reporting) create
coincident offsets; findLastLE landed on the run's last item, leaving
earlier items unmounted and unable to re-measure their re-expanded
content. Walk startIndex back across the coincident run so a re-expand
heals the whole run in one pass instead of one item per scroll.

Also align the VP thought fixtures with production: build the
group → head-id map with buildThoughtHeadIdMap, and pin the harness to
the bottom (SCROLL_TO_ITEM_END) with a tall trailing answer so the
off-screen collapse test exercises the geometry its name claims. Adds
a one-pass-heal regression test.

* fix(cli): anchor to the first item of cached-zero offset runs (#8570)

* fix(cli): keep the VP render window covering the painted viewport (#8570)

* refactor(cli): share the VP coincident-offset walk-back helper (#8570)

* fix(cli): walk the VP targetScrollIndex anchor to the offset-run start (#8570)

The render-phase targetScrollIndex branch anchored mid-run on coincident
offsets while every other anchor path walks back to the run's first item;
healing cached zeros could then drift scrollTop past the healed rows.

Also hoist the VP test harness item component to module scope so harness
rerenders reconcile items in place, matching production's stable
renderVirtualItem over memo(HistoryItemDisplay) instead of remounting
the whole window on every rerender.

* fix(cli): clamp out-of-range VP targetScrollIndex and walk the mount anchor (#8570)

An out-of-range targetScrollIndex made firstIndexOfOffsetRun compare
undefined offsets through the whole hole (undefined === undefined),
decrementing once per hole inside the render phase — a hard freeze for
the SCROLL_TO_ITEM_END sentinel. Clamp the target to the item range
before the walk-back, matching the clamps every other index input
already applies.

Also seed prevOffsetsLength unusable so the first render with usable
offsets re-walks the mount-time targetScrollIndex anchor; seeding with
the mount-time length let an initial anchor inside a coincident-offset
run stay mid-run while every other path resolves to the run's first
item.

* fix(core): align MCP reconnect timeout test with safe replay policy (#8125)

The reconnect-on-timeout test still built its mock tools without server
trust or tool annotations, which the safe replay change now requires
before automatically replaying a connection-loss failure. Update the
fixtures the same way the surrounding reconnect tests were updated,
keeping the test's original assertion that a timeout on a known
disconnected server goes through the reconnect path. Mirrors the same
alignment already landed on main.

* fix(cli): alias externalToolGuard subpath for vitest source resolution (#8125)

This PR added `@qwen-code/acp-bridge/externalToolGuard` imports to cli
serve/acp modules but not the vitest source alias every other acp-bridge
subpath carries. Without it, any vitest run whose acp-bridge dist is
stale or absent fails to resolve the import and the five serve test
files die at transform time. Add the alias following the documented
convention in the config so tests read the live source.

* fix(serve): reject non-ASCII external tool guard bearer tokens

A token outside the ASCII range passed construction but made the
handshake throw ERR_INVALID_CHAR when interpolated into the
Authorization header, blocking qwen serve startup in required mode
with an unexplained error. Enforce printable ASCII (0x21-0x7E) at
validation time so the configuration fails fast with a clear message.

907c7dea70 fix(cli): stabilize thinking block height, replace transcript overlay with inline Ctrl+O toggle (#8077)
* fix(cli): hide streaming thinking preview, rebind Ctrl+O to inline fullDetail toggle

The streaming thinking block showed a 4-line preview that varied in
height due to empty lines in the model's reasoning output, causing
constant page reflow and flicker during generation.

Changes:
- ThinkBody now renders nothing when collapsed (both streaming and
  committed), keeping the block at a stable 1-line header height.
- Ctrl+O now toggles inline fullDetail mode (like Claude Code): all
  thinking blocks, tool groups, and tool results expand/collapse in
  the main conversation view — no alternate-screen overlay.
- Alt+T preserved as hidden shortcut (same toggle, not shown in UI).
- MainContent passes fullDetail to HistoryItemDisplay via the existing
  ThoughtExpandedContext, so the toggle works in both VP and Static
  rendering paths.
- Removed TranscriptView overlay rendering, transcriptItems memo,
  StreamingContext import, and EMPTY_HISTORY_ITEMS constant.
- Removed dead code: tailVisualLines, grow-only height tracker,
  MAX_STREAMING_THINKING_VISUAL_LINES, openTranscript callback.

* fix(cli): update Ctrl+O help text and add thinking-expansion integration test (#8077)

* fix(cli): update docs, help text, and remove transcript dead code (#8077)

* fix(cli): address review feedback on test isolation, dead i18n keys, and missing negative case (#8077)

* fix(cli): add M1 mutation-killing assertion to Ctrl+O test (#8077)

The existing test only asserted clearTerminal (a refreshStatic side
effect) and never verified the setThoughtExpanded state flip.  Under
the vi.mock('ink') harness the mocked App never re-renders from a
directly-called handler, so a behavioural allExpanded assertion is
not possible.  Add a structural guard on the handler source that
fails when setThoughtExpanded is removed (mutation M1 verified).

* fix(cli): strengthen Ctrl+O toggle assertion and document non-VP redraw (#8077)

Tighten the structural M1 assertion from .toContain to a regex that
matches the (prev) => !prev updater pattern, catching mutations like
(prev) => true that the old check would miss.  Document the non-VP
scrollback redraw in keyboard-shortcuts.md per maintainer request.

90052f25ae fix(cli): prevent silent VP-mode crash by adding uncaughtException handler and error visibility (#8088)
* fix(cli): prevent silent VP-mode crash by adding uncaughtException handler and error visibility

VP (alternate-screen) mode swallows all error output: uncaught exceptions
write their stack trace to stderr which lands on the alternate screen
buffer, then gets discarded when teardown switches back to the primary
buffer. The user sees a silent exit with no error message and nothing in
the debug log.

Root cause: no `uncaughtException` handler existed anywhere in the CLI.
PR #7406's ErrorBoundary and unhandledRejection handler only cover React
render errors and promise rejections — synchronous exceptions bypass both.

Changes:
- Add `setupUncaughtExceptionHandler()` with sync debug-log write,
  alternate-screen exit before stderr output, and clean process.exit(1)
- Add `consumeLastRenderError()` to ErrorBoundary for VP main-screen echo
  after unmount leaves the alternate screen
- Remove SIGTERM/SIGINT handlers from kittyProtocolDetector.ts that
  raced with the main signal handlers (#7779)
- Add SIGHUP handler alongside SIGTERM/SIGINT (#7781)
- Guard ThinkBody's MarkdownDisplay with per-item ErrorBoundary so
  partial markdown during thought streaming degrades to plain text

Related: #7971 #7972 #7779 #7781

* fix(cli): consolidate uncaughtException handler into a single listener (#8088)

The VP-crash handler added a second uncaughtException listener that conflicted with the pre-existing one in runCliEntryPoint: the first listener's process.exit(1) ran before the second, leaving the visibility feature inert for real errors, and the new listener lacked the PTY-race guard, crashing the session on benign teardown errors. Replace the startup handler with one session-aware listener (PTY guard, isTTY-guarded alternate-screen leave, writeStderrLineSafe), sanitize the inline render-error fallback, gate the exit-time render-error echo on onError, and cover SIGHUP exit code.

* fix(cli): harden uncaughtException handler and scope render-error echo (#8088)

* fix(cli): address review feedback on VP crash handler (#8088)

- Close over Config instead of sessionId string so the uncaughtException
  handler reads the current session ID at crash time
- Create debug log directory before appending so the write succeeds on
  fresh installs where ~/.qwen/debug/ does not yet exist
- Sanitize error stack with sanitizeTerminalText before writing to stderr
  to prevent ANSI injection on the persistent main buffer
- Add onError debug logging to the ThinkBody ErrorBoundary
- Gate the '(logged to debug file)' hint on isDebugLogFileEnabled() so
  the message is accurate when debug file logging is disabled

* fix(cli): move uncaught-exception helpers to a leaf module (#8088)

gemini.tsx statically imported handleUncaughtException and
isExpectedPtyRaceError from cli.ts, the esbuild entry point. gemini.tsx
is only ever loaded lazily, so that import formed an entry<->lazy cycle;
with splitting enabled esbuild hoisted the entry body into a shared chunk
and left dist/cli.js as a re-export stub. The bootstrap guard at the
bottom of cli.ts then never ran and the bundled CLI exited 0 silently.

Move the helpers (and the private getErrnoCode) into a new leaf module,
utils/uncaught-exception-handler.ts, imported by both cli.ts and
gemini.tsx. cli.ts re-exports them so existing importers (cli.test.ts)
are unaffected, and the handler reuses the shared writeStderrLine from
stdioHelpers.ts. The uncaughtException behavior itself is unchanged.

566d2c1279 fix(cli): stop resize repaint from causing scroll storm (#8009)
* fix(cli): stop resize repaint from causing scroll storm (#8004)

Remove the useResizeSettleRepaint -> refreshStatic wiring that wrote
clearTerminal (destroying scrollback) and remounted <Static> on every
settled resize, re-emitting all conversation history in 50-item chunks.
Ghostty's panel-toggle animation exceeds the 200ms debounce, triggering
multiple settle-repaint cycles per toggle -- visible as continuous
scrolling/flickering.

Ink's dynamic region already re-renders on width changes via
useTerminalSize; modern terminals handle scrollback reflow natively.
The full remount is no longer necessary. The now-unused hook and its
test are removed (no remaining callers).

* test(cli): guard resize no-repaint contract against settle-time regression (#8004)

* test(cli): make resize settle regression test non-vacuous (#8004)

The previous test used rerender() which remounts the tree via ink's
ErrorBoundary (measureElement returns undefined → layout effect throws
→ tree unmounted), so the settle debounce never fired and the test
passed regardless. Rewrite to keep the tree alive (measureElement mock
returns a real value) and deliver width changes to the same mounted
instance via a listener pattern. Mutation-verified: fails when the
removed useResizeSettleRepaint hook is restored.

bfd64114bf fix(cli): reserve Ctrl+Shift+C for terminal copy, not quit/clear (#8011)
* fix(cli): reserve Ctrl+Shift+C for terminal copy, not quit/clear

Ctrl+Shift+C is the standard terminal copy shortcut. The QUIT and
CLEAR_INPUT bindings matched it because they only constrained ctrl
and left shift unspecified, which the matcher ignores. In Kitty-
protocol terminals the escape-hatch check also caught Ctrl+Shift+C
(ESC[99;6u) since it tested ctrl+name without excluding shift.

Add shift: false to both bindings and !key.shift to the escape-hatch
condition so Ctrl+Shift+C passes through to the terminal for copy.
Plain Ctrl+C (shift undefined or false) is unaffected.

Fixes #8006

* test(cli): guard Ctrl+Shift+C paste escape-hatch against !key.shift mutation

The existing Kitty Ctrl+Shift+C test passed identically with or without
the `!key.shift` condition in the Ctrl+C escape hatch, so a regression
making Ctrl+Shift+C clear a stuck paste would ship undetected. Add a
test that enters a stuck keypress-level paste and asserts Ctrl+Shift+C
is buffered as paste content rather than dispatched, which fails when
`!key.shift` is removed.

* fix(cli): remove dead !key.shift escape-hatch guard (#8011)

The KeypressContext.tsx escape-hatch guard added in bb86d57 is
unreachable: Node readline never produces a Key with ctrl=true,
name='c', and shift=true for any terminal encoding (kitty,
modifyOtherKeys, or legacy 0x03). Mutation test M2 confirmed
reverting this hunk has zero effect on the test suite.

Remove the guard and the two tests that exercised it. The
keyBindings.ts shift:false fix (the load-bearing change proven by
M1) and its keyMatchers tests are untouched.

9bbd394cb2 fix(cli): map Kitty Super (Command) modifier to meta (#7996)
* fix(cli): map Kitty Super (Command) modifier to meta

Kitty-protocol terminals forward Cmd+C as a CSI-u sequence whose modifier
parameter carries the Super bit (8), which the parser silently dropped. The
key then parsed as a bare printable "c" (meta: false) and leaked into the
input box even though the terminal performed the copy itself. Fold the Super
bit into the emitted meta flag at every Kitty modifier decode site so
Super-modified keys are no longer inserted as text.

Fixes #7990

* test(cli): cover Super-bit fold on reverse-tab and functional-keys paths (#7996)

* test(cli): make functional-key Super-bit case load-bearing

Use Home (ESC [ 1 ; 9 H) instead of Up arrow (ESC [ 1 ; 9 A): readline
claims modified arrows before the Kitty arrowPrefix decoder, so the arrow
case passed even without the Super-bit fold. Home exercises the decoder
and fails on unfixed code.

4c11e21bcd fix(cli): prevent SGR mouse events from being swallowed as paste on Windows (#7988)
On Windows (pasteWorkaround path), shouldFlushRawDataAsPaste
misclassifies raw stdin data containing both a carriage return (0x0d)
and an SGR mouse sequence as pasted content. The synthetic paste
wrapper sets isPaste=true in handleKeypress, which discards SGR mouse
data via resetSgrMouse(), breaking wheel scrolling in VP mode.

This commonly triggers when Enter (\r) and a subsequent mouse wheel
event arrive in the same stdin chunk — a frequent occurrence on
Windows Terminal. macOS is unaffected because handleStdinData does
not use this heuristic.

Skip the paste heuristic when the buffer contains ANSI escape bytes
(0x1b) so SGR mouse sequences always reach readline for proper
parsing and dispatch to mouse subscribers.

Closes #7964

81f1ffb94c fix(cli): correct hardware cursor off-by-one in fullscreen mode (#7998)
* fix(cli): correct hardware cursor off-by-one in fullscreen mode

In fullscreen mode Ink omits the trailing newline, so after writing
output the terminal cursor sits ON the last line rather than one past
it. buildCursorSuffix assumed the latter and emitted one extra
cursorUp, placing the hardware cursor (used for IME positioning) one
row above the software block cursor — visible as an extra white
rectangular segment protruding above the input line.

Pass a hasTrailingNewline flag through buildCursorSuffix,
buildReturnToBottom, buildCursorOnlySequence, and
buildReturnToBottomPrefix in the Ink patch so both the standard and
incremental log-update renderers compute the correct cursor movement.

Closes #7980

* fix(cli): revert incorrect hasTrailingNewline in buildReturnToBottom

Self-review caught that buildReturnToBottom does NOT need the
hasTrailingNewline adjustment: its previousLineCount argument comes
from str.split('\n').length, which already includes the trailing
empty element when the output ends with '\n'. The original formula
(previousLineCount - 1 - y) is the exact inverse of the corrected
buildCursorSuffix in both fullscreen and non-fullscreen modes.

Only buildCursorSuffix needs the flag, because its visibleLineCount
argument excludes the trailing empty element.

PR #7062 hid the sticky panel when streamingState is Idle, but the panel
resurfaces with stale todos from a previous turn as soon as the user sends
a new message (state → Responding). This is confusing — the user sees
in-progress indicators for work that already finished in an earlier turn.

Add a turn-boundary check in getStickyTodos: if a user message exists
after the todo snapshot in history, the snapshot belongs to a previous
turn and the sticky panel returns null.

ChiGaoand秦奇 0bafd0db21 fix(core): auto-retry transient network errors during API calls (#7898)
* fix(core): retry on transient network errors in defaultShouldRetry and API-call predicate

The retry classification layer (classifyRetryError) already recognizes
transport errors (ECONNRESET, ETIMEDOUT, etc.) as retryable, but neither
defaultShouldRetry nor the inline shouldRetryOnError in geminiChat.ts
consulted the classification for transport codes. TCP-level errors carry
no HTTP status, so they fell through every predicate and propagated as
raw [API Error: terminated (cause: read ECONNRESET)].

Wire the existing classifyRetryError transport detection into both
retry decision points:

1. defaultShouldRetry in retry.ts — append a transport-kind check after
   the existing rate-limit / 5xx predicates, preserving all current
   behavior (including bounded retry for fail-fast quota 429s).
2. Inline shouldRetryOnError in geminiChat.ts makeApiCallAndProcessStream —
   add the same transport-kind check so the API-call-level retryWithBackoff
   wrapper covers network errors.

The stream-level transport retry (gated on !streamYieldedChunk) already
exists and is unchanged.

ChiGaoand秦奇 7f99a1f298 fix(cli): patch ink to clear staticNode on indirect subtree removal (#7816)
When a component containing <Static> is unmounted (e.g. transcriptFreeze
toggling <App/> off), the reconciler removes the ancestor and
freeRecursive() frees the static node Yoga WASM memory. The existing
identity check (staticNode === removeNode) only catches direct removal
of <Static> itself -- removing an ancestor leaves a dangling staticNode
reference. The next render then calls getComputedWidth() on freed WASM
memory, crashing with RuntimeError: memory access out of bounds.

Add clearStaticNodeIfContained() which walks up the parent chain from
staticNode to detect ancestor removal, and null out removeNode.yogaNode
after cleanup so stale JS references short-circuit on ?.yogaNode.

* fix(cli): align all TUI icon columns to a uniform 2-col width

Remove the extra left padding (paddingX=1) from ToolMessage and
CompactToolGroupDisplay that caused tool status icons (✓, ✗) to be
indented relative to the assistant message prefix (◆).

Reduce STATUS_INDICATOR_WIDTH from 3 to 2 so the tool status indicator
column matches the prefix width used by conversation and status
messages. Add flexShrink={0} to prefix boxes that were missing it.

Unify CompressionMessage, SummaryMessage, and MemorySavedMessage to
use the same fixed-width prefix box pattern (width=2, flexShrink=0)
instead of ad-hoc marginRight or minWidth approaches.

Restructure tool_use_summary in HistoryItemDisplay to use the
standard prefix box pattern instead of inline paddingLeft.

This ensures all icons (◆, ✓, ✗, ●, △, etc.) start at the same
column and all text content begins at a uniform offset, regardless
of whether the icon glyph is 1 or 2 terminal columns wide.

* fix(cli): address review feedback on icon alignment PR

- Remove dead COMPACT_GROUP_HORIZONTAL_PADDING constant (now 0)
  and its no-op subtraction from the height estimation formula.
- Reduce TMUX_SPINNER_FRAMES from 3-char to 2-char equivalents
  ('. ' / '..') so they fit the narrowed 2-col indicator box
  without overflowing in tmux sessions.

* fix(cli): force narrow presentation for ambiguous-width TUI icons

Append VS15 (U+FE0E, Variation Selector 15) to all East-Asian-Width
'Ambiguous' icon glyphs (◆ ● △ ○ ◎ ※ ∴ ∵ ★ ◉) via a central ICON
constant map in constants.ts. VS15 forces the terminal to render these
glyphs in their narrow (1-column) text presentation, matching
string-width's default ambiguousIsNarrow=true calculation.

Without this, CJK terminals render ambiguous glyphs as 2 columns while
Ink's layout engine allocates 1, causing a 1-column visual drift that
breaks icon/text alignment in the conversation view.

25 files updated to use ICON.XXX constants instead of raw string
literals for ambiguous icons.

* fix(cli): update test assertions for VS15 icon changes

- Fix 17 inline test assertions across 7 test files to match
  VS15-appended icon output
- Fix MarkdownDisplay.tsx: use stringWidth(prefix) instead of

+25 86103203e4 fix(cli): correct queued message display style and ordering (#7381)
* fix(cli): correct queued message display style and ordering

Mid-turn steer messages (user input queued while the model is
responding) had two display bugs:

1. They rendered with notification styling (● icon) instead of
   user-input styling (> prefix) because accept() added them to
   UI history as MessageType.NOTIFICATION.

2. They appeared below the model's reply because accept() was
   only called in the finally block after the entire response
   stream completed, appending the user message after all model
   response items.

Fix: use MessageType.USER with sentToModel: true for steer
messages, and settle the steer input on the first stream event
(after the user-content push lands but before model-response
events are committed to UI history). Pass steer inputs through
to recursive sendMessageStream calls so all takeSteerInput paths
benefit from early settlement. Add a WeakSet guard to
settleSteerInput for idempotency across recursive invocations.

* test(core): add ordering test for early steer settlement

* fix(cli): use sentToModel: false for steer messages, address review

- Use sentToModel: false instead of true: steer messages are injected

  turns, inflating the rewind turn index.

* fix(cli): exclude steer messages from user-turn filters (#7381)

Steer messages (sentToModel: false) were counted as real user turns by

recall, away-recap thresholds, and resume collapse boundaries.

subagentDispose assignment in the non-fork branch it actually documents.

* fix(core): close finishing window and release resident on error in background GOAL path

- Non-worktree GOAL completion drained the message queue but never called
  registry.beginFinishing(), unlike the worktree path. A send_message racing
  the terminal transition could be accepted (status still running,
  finishingAgents empty) and then orphaned by complete(). Call beginFinishing()
  after the empty drain to reject the racing message instead.
- The completion catch block never reset keepResident, so a throw from
  patchAgentMeta/registry.complete left the runtime resident but finalized as
  failed — a zombie that cleanupRuntime never reclaimed. Reset keepResident in
  the catch so the finally block disposes it.

* fix(core): strip Qwen-internal daemon secrets from agent-spawned child env (#7256)

* fix(core): strip Qwen-internal daemon secrets from agent-spawned child env

Shell subprocesses (and the monitor tool and stdio MCP servers) inherited
the full daemon process.env, including QWEN_SERVER_TOKEN (the serve-daemon
bearer credential), so an agent-run command like printenv QWEN_SERVER_TOKEN
could read an internal secret. Add a shared sanitizeChildEnv() that removes
Qwen-internal daemon/server tokens (QWEN_SERVER_TOKEN, QWEN_DAEMON_TOKEN)
before spawning, and apply it at the shell child_process + PTY paths,
monitor.ts, and the mcp-client stdio transport.

The denylist is deliberately narrow: it does NOT strip third-party
credentials (GH_TOKEN, AWS_*, NPM_TOKEN, ...) that real shell workflows
legitimately inherit -- only Qwen-internal secrets. Exported from the
package root so the desktop denylists can consolidate onto it later.

Fixes #6601.

* fix(cli): insert newline on Shift+Enter and stop streaming thinking-block flicker (#7397)

* fix(cli): re-push Kitty keyboard flags onto the alternate screen in VP mode

In VP mode the app renders on the alternate screen (`alternateScreen: true`),
but the Kitty keyboard progressive-enhancement flags were pushed only once at
startup on the main screen. The Kitty spec tracks these flags per screen
buffer, so the alternate screen's stack stays empty and the terminal never
reports modifiers: Shift+Enter arrives as a bare Enter (submit) or, when the
terminal emits an ESC-prefixed variant, as an orphaned Escape that trips the
empty-buffer double-Esc rewind prompt — so Shift+Enter can never insert a
newline in VP mode even on Kitty-capable terminals (e.g. cmux).

Re-push the flags onto the alternate screen right after Ink enters it (Ink
writes the enter-alt-screen sequence synchronously inside render(), so the
push is correctly ordered). Ink discards the alternate screen and its flag
stack on unmount, leaving the startup main-screen push balanced by the
existing disableKittyProtocol() on cleanup.

* fix(cli): stabilize streaming thinking block height to stop flicker

The pending "Thinking…" block renders the tail of the reasoning stream in a
content-sized box. As the model emits paragraph separators, a blank line
enters and leaves the tail window (and `trimEnd` drops trailing blanks), so the
visible line count oscillates and the block flickers 2→3→5 rows during
streaming.

Track the tallest height the block has reached for the current thought and
never render fewer rows than that (capped at the streaming window size),
padding at the top so the newest line stays pinned to the bottom. The tracker
resets when streaming ends or when the buffer shrinks (a new thought replaced
it), so height is monotonic within a thought without leaking across thoughts.

* fix(cli): decode xterm modifyOtherKeys Shift/Ctrl/Alt+Enter so it inserts a newline

Terminals such as Ghostty report Shift+Enter as the xterm modifyOtherKeys
sequence `ESC [ 27 ; <mods> ; <key> ~` (e.g. `ESC [ 27 ; 2 ; 13 ~`) when the
Kitty keyboard protocol is not negotiated — which is the default, since Kitty
detection does not always succeed. Two bugs kept this from inserting a newline:

1. The CSI-u parser read the leading `27` marker as the key code (matching the
   Escape key code 27) instead of the real key code in the third parameter, so
   with Kitty enabled Shift+Enter was mistaken for Escape and tripped the
   double-Esc rewind prompt.
2. The reassembly path that stitches readline's shredded CSI fragments back
   together was gated behind `kittyProtocolEnabled`, so with Kitty disabled the
   `ESC [ 27 ; 2 ;` head plus the stray `13~` tail leaked into the composer as
   literal text and no newline was inserted.

Decode the third parameter as the real key code for the `27;…~` form, and route
those sequences through the reassembly buffer even when Kitty is off (only the
`ESC [ 27` marker opts in, so keys readline already parses cleanly are
untouched). Shift/Ctrl/Alt+Enter now insert a newline in both VP and non-VP
mode regardless of Kitty negotiation.

* fix(cli): anchor VP viewport to the top until a conversation turn exists

On a fresh VP-mode session the virtualized list holds the banner plus startup
notices (tips / MOTD / info), so it is longer than one item. Keying the initial
scroll anchor off list length alone selected scroll-to-end, which pinned the
banner to the bottom of the full-height viewport and left the top half of the
screen blank.

Anchor to the top until there is an actual conversation turn (a user/user_shell
history item or a pending response), then resume scroll-to-end so the latest
output stays in view. Startup notices no longer count as content that forces
bottom alignment.

* fix(cli): stabilize streaming thinking window against availableTerminalHeight drift

The grow-only streaming thinking window still flickered because its line cap was
derived from availableTerminalHeight. While a thought streams the terminal keeps
constrainHeight on, so availableTerminalHeight (and the derived maxLines) drifts
up and down as sibling pending content grows, and the grow-only clamp
`min(maxLines, …)` shrank the block whenever it dipped.

Use a constant window height (MAX_STREAMING_THINKING_VISUAL_LINES) for the
pending window instead. The window is only a few lines, so a fixed cap cannot
meaningfully overflow (VP scrolls anyway), and the height stays stable while
still growing monotonically within a thought.

* docs(autofix): require evidenced pre-commit verification, not a bare "verified" (#7486)

* docs(autofix): require evidenced pre-commit verification, not a bare "verified"

The skill already said to run build/typecheck/lint/Vitest before
committing, but softly — and #7408 committed a fix with a TS error the
gate then rejected while its summary claimed "verified all 3 commits".
A self-assessment the gate contradicts wastes a whole round.

Strengthens the address-review contract from "run the checks" to:
- actually run them, do not assert them from reading the diff;
- if typecheck or a touched-package test fails, do NOT commit — treat
  the feedback as unresolved (failure.md);
- end address-summary.md with a `## Verification` section listing each
  command run and its result; a bare "verified" is not acceptable.

The framing is structural, not etiquette: the deterministic gate re-runs
the same commands and discards the round on any failure, so skipping them
only moves the rejection later. Pinned by a test so it cannot soften back.

This is the checkable half of "audit before committing" — the
undirected/reverse-audit-until-clean practice does not transfer to an
unsupervised agent (no verifiable stopping condition, and it worsens the
timeouts seen on large PRs), but "run the gate's own checks first and
show the evidence" does.

* feat(autofix): stop a PR that fails to push for N rounds in a row

Under takeover the round cap is 100, which is right for a PR that needs
many PRODUCTIVE rounds. It is wrong for one that fails every round: #6723
ran 7 consecutive failed rounds (3 agent timeouts at 50 min, 4 gate
rejections whose fix broke tests) over 8 hours, heading for round 100,
because it is a 5700-line, 47-file, 5-day-old PR racing a fast-moving
main — every round re-resolves a conflict it cannot finish or that fails
the gate. Retrying at the same per-round budget will not converge; a
human has to rebase or split it.

Adds CONSECUTIVE_FAILURE_CAP (5), distinct from the total round cap. The
handoff step already runs only when a round did NOT push, so it counts
the unbroken run of prior failure markers — stopping at the first push
("Addressed the latest review feedback") or legitimate no-op ("no
changes needed"), either of which proves progress and resets the streak.
At the cap it forces the terminal round even under takeover, with a
handoff that names the real fix (rebase/split, then /retry). Cause-
agnostic: a timeout and a gate rejection both count.

* fix(autofix): address review feedback on consecutive-failure circuit breaker (#7482)

* feat(core): restore background agent roster (#7459)

* feat(core): restore background agent roster

* fix(web-shell): add list_agents to TOOL_DISPLAY_NAMES

The new list_agents core wire tool was added to core's ToolNames but not
to the web-shell TOOL_DISPLAY_NAMES map, causing toolFormatting.drift.test.ts
to fail (expected ['list_agents'] to deeply equal []). Add the missing
'ListAgents' display-name entry so the browser panel shows a friendly name
instead of the raw wire name and the drift guard passes.

* fix(cli): reload old-session background agents on failed resume rollback

When /resume fails after core has swapped but before the UI swap, the catch
block rolls core back to the old session via startNewSession(oldSessionId).
However the forward path already called resetBackgroundStateForSessionSwitch,
which cleared the old session's in-memory background agents. The rollback did
not reload them, so list_agents returned empty for the old session (whose
sidecars are still on disk) until the next process start or successful resume.

Reload the old session's paused background agents after rolling core back, so
the restored roster matches on-disk state. Placed after startNewSession so the
loadPausedBackgroundAgents current-session guard is satisfied; best-effort via
.catch so it never blocks the rollback path.

* fix(web-shell): add zh translation for list_agents tool name

The toolFormatting test 'has a zh translation for every tool in the
display-name map' failed with expected ['list_agents'] to deeply equal []
because list_agents was added to TOOL_DISPLAY_NAMES without a matching
toolName.list_agents zh-CN entry. Add the translation to restore parity.

* fix(cli): resolve CI failures for background-agent roster restore

- Add toolDisplayName.ListAgents translations (en, zh, zh-TW, ca) so the
  new list_agents tool has a zh entry; fixes i18n/index.test.ts.
- Add loadPausedBackgroundAgents and consumePendingRecoveredAgentsNotice
  to the acpAgent worktree test config mock, which loadSession now calls
  via #restoreBackgroundAgentsOnResume; fixes acpAgent.worktree.test.ts.

* refactor(core): extract incompatible-isolation blocked reason to a const

Move the incompatible-isolation blocked-reason string out of an inline
literal into a module-level INCOMPATIBLE_ISOLATION_BLOCKED_REASON const,
matching its four sibling reasons so the text is discoverable by
constant-name grep and edited alongside the others.

* fix(core): preserve retained activity state on failed agent revive

Address review feedback on the background-agent roster restore:

- On a failed completed-agent revive, restore UI state with a non-empty
  guard instead of `??`. Because `restorePausedEntry` resets the paused
  entry's `recentActivities` to `[]`, the previous `failedEntry?.field ??
  completedEntry.field` kept that empty array and dropped the pre-revive
  snapshot (the UI Progress section rendered empty). Applied consistently
  to pendingMessages, recentActivities, and pendingApprovals.

Add regression coverage for previously untested paths:

- failed revive preserves pre-revive recentActivities
- terminal-agent cap admits only the newest MAX_RETAINED_TERMINAL_AGENTS
  completed sidecars on restore
- /resume rollback reloads the old session's background agents
- headless resume prepends the recovered-agents notice to the prompt

* test(cli): cover interrupted-turn continuation not consuming recovered-agents notice

Add ACP and headless regression tests asserting an interrupted-turn
continuation does not consume the one-shot recovered-agents notice
(the !isContinue / !continueInterrupted guards), so it is delivered on
the user's next ordinary prompt. Mirrors the existing slash-command
coverage.

* fix(core): harden the usage salvage around session deletion (#7425)

Post-merge review follow-ups on #7391 (three findings):

- Salvage the archived transcript in the active-branch deletion too:
  when both copies co-exist (an interrupted archive) and the fresh
  active transcript carries no telemetry, the archived copy holds the
  session's usage history and was deleted unsalvaged. The dedup guard
  makes the extra call a no-op whenever the active copy already wrote.
- Enforce the "never blocks deletion" contract at the call site: a
  salvageUsageBestEffort wrapper catches and warns, so the guarantee is
  structural rather than an implementation detail of
  persistUsageBeforeTranscriptDeletion. The new failure-tolerance test
  (salvage rejects -> deletion still succeeds) fails without the
  wrapper — the bare await let the rejection escape through
  removeSessionFiles' rethrowing catch.
- Clear the salvage module mock in beforeEach so the wiring test's
  invocationCallOrder assertions can never read stale calls.

* test(core): stub the registry methods agent.ts actually calls (#7538)

The shared stubRegistry in agent.test.ts was missing six methods that
agent.ts reaches: bridgeApprovalEvents, getQueuedCount,
registerResidentAgent, restartCompletedAgent, unregisterResidentAgent and
waitForMessages.

That is not a benign omission. The background body wraps its work in a
try/catch that routes any throw into registry.fail(), so a missing method
never surfaces as 'not a function' — it silently converts a successful
run into a failed one. On the GOAL completion path
unregisterResidentAgent is called immediately before complete(), so the
TypeError replaced the completion entirely:

  registry.fail('fork-...', 'registry2.unregisterResidentAgent is not a
  function', ...)

That is what broke 'runs a non-interactive fork through the background
registry' on main. #7460 added the registry.complete assertion, which
exposed the incomplete stub — before it, nothing checked whether the
background body finished successfully and the TypeError was swallowed.

Stub all six with their real return shapes (unregisterResidentAgent
returns boolean, bridgeApprovalEvents returns the unsubscribe callback
agent.ts later invokes, waitForMessages resolves to a list) and assert
registry.fail was not called before asserting completion, so a future
gap reports the actual error instead of 'complete: 0 calls'.

* fix(ci): don't let one failing scenario sink the whole visual preview (#7511)

The web-shell visuals render runs every screenshot and flow in a single
`test:e2e:visuals`, and that step had no `continue-on-error`, while the compose
and upload steps had no `if: always()`. So one failing or timing-out scenario
failed the job, the artifact was never uploaded, and the publish workflow had
nothing to post — the entire preview vanished even when every other scenario
passed and its PNG was already on disk. A flow (a long multi-click sequence) is
the most fragile scenario kind, so the fragile one silently takes down the
deterministic screenshots. PR #7498 hit exactly this: 29 scenarios passed, one
new channel-management flow timed out, and the PR got no preview and no comment
at all.

Make the after-capture step `continue-on-error` so the passing captures survive
and the later steps still compose and upload them. The publish job only runs on
a `success` conclusion, so the job must stay green — but a masked failure must
not read as a clean preview. Ship the step's real `.outcome` (which
continue-on-error does NOT mask, unlike `.conclusion`) to the publisher as
`render-status.txt`, and have the comment builder use it: an empty preview whose
render failed says "one or more scenarios failed to render" and is explicitly
NOT the reassuring green check or the coverage-gap prompt (both imply the render
ran); a partial preview is labelled partial above the shots that did render. A
missing status file (older run) defaults to complete, so this only ever adds a
warning, never suppresses a real preview.

* feat(web-shell): add renderChatHeader slot for custom session header (#7553)

* fix(cli): say review coverage gaps in the author's units, not chunk ids (#7550)

The posted review body rendered coverage disclosures with the run's own
bookkeeping as subjects: bare chunk ids, unsorted, one per subject. On a
run that certified nothing (PR #7268) the body enumerated all 49 chunk ids
across two sentences while opening with "Reviewed. Suggestions are
inline." — the opener certified the exact thing every following sentence
took back, and nothing on the PR page maps a chunk id to code.

Three changes, all render-time — the structural entries, the caps, the
caller-echo dedup and the stderr remediation still key on chunk ids, which
is where the id is the selector a reader can act on:

- Coverage now returns the plan's chunk→files table (DiffChunk.files was
  already in the plan JSON; the coverage type slice dropped it).
- compose-review renders chunk gaps through describeChunkGap: every
  planned chunk collapses to "the entire diff", a narrow gap with known
  files names the files, and anything wider is counted against the plan's
  total. Applied to the receipt sentence, the uncoverable sentence (bare
  CLI entries only — caller-authored entries render verbatim) and the
  grouped per-cause sentences.
- The COMMENT opener may no longer say "Reviewed." over a disclosure set
  that denies it: when no chunk is both covered and undisclosed — or no
  chunk universe could be read at all — it opens with a zero-certified
  warning instead. A rewritten launch demonstrably read its chunk, so
  coverage alone is not the test; certified is covered with no disclosure
  against it.

* fix(autofix): retry a skipped-Prepare instead of stranding the PR terminal (#7490)

* fix(autofix): retry a skipped-Prepare instead of stranding the PR terminal

A base/infra failure BEFORE the agent runs was misread as an agent crash
and terminated the PR forever. When an early step fails — installing or
building the trusted base, checkout, node setup — the `Prepare branch and
feedback` step is skipped, so NEWEST is empty, and the report step's
"crashed before reading feedback" branch fired: MARK_ROUND=MAX_ROUNDS,
terminal, scan skips it on every future tick.

Observed: a web-shell TypeScript break on `main` failed `Install
dependencies and build` (which builds the trusted base) across a whole
scan batch, and SIX healthy PRs were stranded terminal at round=100 in
one run — including ones at round 9 and 11 that had nothing to do with
the break. `round=100` there is a terminal sentinel, not 100 attempts.

NEWEST-empty now splits on steps.prepare.outcome:
- 'skipped' (an earlier step failed, the agent never ran) is infra/base
  and transient: retry with a sentinel ts so the feedback stays live,
  incrementing the round so a PERSISTENTLY broken base is still bounded
  and stops at the cap (recoverable with /retry).
- 'success'/'failure' (Prepare ran, no feedback produced) is a genuine
  pre-read agent crash: unchanged terminal behaviour.

This is the reverse of the asymmetry #7482 addresses: that bounds a
crash AFTER reading that retried forever; this stops a transient failure
BEFORE reading from going terminal after one.

* docs(autofix): note a pre-Prepare cancel also retries intentionally (#7490)

* fix(autofix): also retry a cancelled/empty prepare outcome, not just skipped

A previous review comment on this PR noted that a job cancelled before
Prepare should retry too. It was right about the intent but the code did
not do it: `steps.prepare.outcome` is 'cancelled' for a cancel and '' for
a job that stopped before Prepare entered the step context — both DISTINCT
from 'skipped', so `== 'skipped'` sent them to the terminal branch, the
same over-termination this PR exists to fix.

Match on "not a real Prepare run" (`!= 'success' && != 'failure'`)
instead, so skipped, cancelled, and empty all retry; only a Prepare that
actually ran to a verdict (success/failure) with no feedback stays
terminal — the genuine pre-read agent crash. Test extended to drive the
cancelled and empty cases (retry) and both real-run outcomes (terminal);
mutation-verified that reverting to `== 'skipped'` reddens the cancelled
case.

* test(autofix): update the pre-read-crash case for the broadened retry

The prior commit broadened NEWEST-empty retry to skipped/cancelled/empty
but left the older 'replays the handoff decision' test asserting the old
terminal behaviour for an unset PREPARE_OUTCOME (which now retries). That
test's terminal cases now set PREPARE_OUTCOME=success/failure explicitly —
the only outcomes that still terminate — so it exercises the genuine
pre-read agent crash rather than the infra/cancel path.

* test(autofix): anchor the skipped-Prepare extraction past the CONSEC block

CI reddened `retries a skipped-Prepare` after main's consecutive-failure
cap (#7482) merged into this branch: that block was inserted between this
decision block and the report `{`, and it calls `gh api`. The test's
`{`-anchored regex over-captured through it, so the extracted script ran
the unstubbed `gh api` and failed. Anchor the end on the same
`# Consecutive-failure` comment the sibling gate-crash test already uses,
so the extraction stops at this decision block's own closing `fi`.

* fix(autofix): exempt skipped-Prepare from the consecutive-failure breaker

A broken base build skips Prepare, producing no API error file — so the
consecutive-failure breaker ran on the new retry path and, after 5
scans, re-introduced the exact mass-stranding this PR exists to prevent.
Exempt pre-agent infra failures (skipped/cancelled/empty outcome) from
the breaker, mirroring the transient 429/5xx exemption: same failure
class (not the PR's fault, self-heals, hits the whole batch). The round
cap + sentinel-ts /retry recovery already bounds a persistently broken
base.

Also trim "checkout" from the retry headlines (checkout failures do not
land in this branch) and hoist the duplicated MARK_TS assignment.

* fix(autofix): reset the consecutive-failure streak on prior infra-failure markers

The streak walker counted prior infra-failure headlines ("AutoFix could
not start —…") as failures, inflating the consecutive-failure count on
subsequent rounds.  A PR with 3 real agent failures, then 3 rounds of
base-build infra failures, then 1 more real failure would trip the
cap-5 breaker even though only 4 rounds were the PR's fault.

Add the two infra-failure headline patterns as reset strings in the
streak walker, alongside the existing push and no-op resets.  The
genuine agent-crash headline ("AutoFix could not start evaluation —…")
is deliberately excluded — it is a real failure and must still count.

* fix(autofix): clarify infra-failure headlines and else-branch comment (#7490)

Address review nits: the retry headline now mentions cancelled runs,
the cap headline says 'reached the round cap' instead of overstating
'could not start for N rounds', the else-branch comment says 'prepare
itself crashed' instead of 'agent crash', and the streak-reset pattern
is simplified now that both infra headlines share the same prefix.

* fix(cli): keep role codenames and brief paths out of the posted review body (#7560)

The posted body still carried two operator registers #7550 left in place:
roster role subjects rendered their internal codenames ("Agent 1c:
Cross-file tracer", "Test coverage matrix (whole-diff)"), and an unread
brief's disclosure interpolated its filesystem path. And when verify and
the reverse audit failed the same way, the body said it twice, in two
near-identical sentences.

- Every Brief now carries a publicLabel — the dimension said as what it
  checks ("the cross-file consistency pass") — and coverage's structural
  disclosures carry it as publicSubject beside the internal subject, plus
  a path-free publicReason for unread briefs. The internal label and the
  path stay on stderr, where they are the selector an operator acts on;
  every dedup and certification check still keys on the internal subject.
- compose-review renders the public fields and groups by the reason the
  body PRINTS, so two unread briefs share one path-free sentence instead
  of repeating it per role.
- verificationGaps merges verify and reverse-audit failures of the same
  delivery shape into one sentence with both subjects and both
  consequences; mixed shapes keep their precise per-role texts, and the
  per-role rebuild commands stay on stderr either way.

* fix(autofix): retry an agent timeout instead of advancing past its feedback (#7563)

A timeout evaluated NOTHING — the agent ran out of budget before finishing,
so nothing was committed and the feedback is unaddressed. It was treated as
an evaluated verdict (real ts, watermark advances), which strands that
feedback: the next scan sees "nothing new" and never retries. Observed on
#7471 (round 13/100), a heavily-reviewed 1871-line PR: rounds 11 and 13
timed out, but round 12 pushed — so a timeout is transient far more often
than not, and advancing past it left the round-13 feedback unhandled.

run-agent.mjs now drops an `agent-timeout` signal on result.timedOut, and
the handoff routes it like a pre-verdict crash: sentinel ts (feedback stays
live) and a retry, with a headline that names the real fix at the cap
(split the PR or raise the budget). A PR that PERSISTENTLY times out is
bounded by the round cap and the consecutive-failure cap, so this cannot
loop forever — it just stops treating a one-off budget blip as a verdict.

The loop guard stays terminal (a tool-call loop is a real defect, not a
budget blip). An API error still routes to its own model-key handoff; the
timeout signal is written only when NOT an API error.

uuid.UUID() accepts several non-canonical spellings — braced

through after the RFC 4122 variant check. The value is then forwarded to
the CLI verbatim as --session-id/--resume, producing a malformed session
id downstream rather than a clear error at the SDK boundary.

Reject anything whose canonical form differs from the input. Case is
deliberately not part of the comparison: UUID() lowercases, and an
all-uppercase spelling is still valid canonical input.

* fix(feishu): await stream cancels in media download teardown (#7465)

* fix(feishu): await stream cancels in media download teardown

downloadMedia left two reject paths' stream teardown unawaited:

- the oversize-stream path called reader.cancel() without awaiting, so a
  cancel error during teardown became an unhandled rejection (fatal under
  Node's default --unhandled-rejections=throw);
- the Content-Length reject path returned without cancelling resp.body,
  leaving the connection pinned until GC.

Both were already fixed for the sibling DingTalk downloader in #7361 (which
was itself modelled on this Feishu code), so this brings Feishu to parity.
Adds a regression test that pins the reader.cancel() await via a rejecting
cancel, plus an assertion that the Content-Length path releases the body.

* test(feishu): cover a rejecting body.cancel() on the Content-Length path

Mirrors the existing reader.cancel() teardown test for the other reject
path, per review feedback. Removing the await on resp.body?.cancel()
flips execution onto the 'rejected: size ... exceeds' branch and the
test fails.

* fix(autofix): make the review-address report wrapper lines bilingual (#7569)

The agent's address-summary.md / no-action.md already ends with a
collapsed Chinese translation, but the workflow-appended wrapper lines
around it — the "Addressed/Reviewed the latest feedback" lead-in, the
"Base-conflict check" line, and the "Re-review when you have a moment"
footer — were English-only and sat outside that block. So the posted
comment was only half translated, unlike the takeover-ack comments
(full collapsed Chinese block) and the "model/模型" sign-off in this
same report (already inline-bilingual).

Give each wrapper line an inline Chinese translation, matching the
model/模型 idiom. The English halves are preserved verbatim — the
streak-reset detector globs on "Addressed the latest review feedback"
and "no changes needed", and a test extracts these lines — so behaviour
is unchanged and old English-only comments still match. A new test pins
each English-Chinese pair so a future reword that drops the Chinese
fails. The terminal handoff/failure comment is left English-only for
now (SKILL.md keeps it so by design); that is a separate change.

* feat(cli): post the review body bilingually when the PR description is Chinese (#7564)

When the PR author writes Chinese, the posted /review body was
English-only. fetch-pr now records whether the PR description contains
Han characters (prDescriptionHasHan, detected from the same gh pr view
call and stamped into the plan report), and compose-review renders the
body bilingually off that flag: the English body leads, the complete
Chinese version rides collapsed in a <details><summary>中文说明</summary>
block, and the model footer stays outside the fold. The signal is the
CLI's own — the caller cannot toggle the register of a certified body —
and a local plan has no field, so nothing changes for terminal-only
reviews.

Every deterministic body fragment carries an en/zh pair end to end:
compose-review's clause templates and describeChunkGap phrases, the
coverage disclosures (reasons, publicLabel role subjects via a new
publicLabelZh, the path-free unread-brief reason) and the Step 4/5 gap
texts including the combined same-shape sentence. Fragments with no
deterministic translation — model-written findings, caller echoes,
interpolated errors — ride verbatim in both halves. verificationGaps now
returns structural {subject, reason, subjectZh, reasonZh} entries, which
also removes compose-review's last recover-the-boundary-from-prose parse.

SKILL.md instructs the same format for the model-authored inline
comments: English finding first (marker and suggestion block stay in the
English half — tooling filters on them), full Chinese translation
collapsed beneath, footer last.

* feat(autofix): auto-rerun a check that died on infrastructure, once (#7562)

* feat(autofix): auto-rerun a check that died on infrastructure, once

A failed check can be red because the machine died, not the code — a
self-hosted runner losing the server, the disk filling. #7490's E2E
failed with "runner lost communication with the server" and went green
on a rerun. The scan now reruns such a check's failed jobs automatically.

Detection is a conservative annotation whitelist (INFRA_FAILURE_SIGNATURES)
— only unambiguous machine failures, never a test-level timeout, which
could be a real regression. The one-shot guard is run_attempt, not a
marker: a run already retried to attempt 2 and still infra-failing is
persistent, so it is left for a human; after a rerun the attempt
increments, so the next scan will not rerun it. Every step is fail-safe
(any API error → no rerun), it runs only when the PR actually has a
failed check, and the gate carries the same review-address carve-out as
the other check selectors so the loop never reruns its own runs.

This is the transient-infra sibling of #7554 (stale-base): that merges
current main when a check is base-inherited; this reruns when a check
died on the runner. Neither touches a check that is a genuine failure.

Note: rerun-failed-jobs needs the PAT to hold `actions: write`.

* fix(autofix): use POSIX ERE groups in infra-failure regex, cover all signatures in tests (#7562)

* fix(autofix): also treat a git fetch/clone transport death as infra

#6506's checkout died mid-transfer — "fetch-pack: invalid index-pack
output" and "RPC failed; curl 92 ... CANCEL" — which then hung the job
into the 20m limit. That is infra, not the PR (it only touches a doc),
and a re-run made it green. But the infra-signature whitelist did not
cover it, so the auto-rerun did not fire and it waited on a human.

Add `invalid index-pack output` and `RPC failed` — the two canonical
git-transport-death phrases — to INFRA_FAILURE_SIGNATURES. A co-present
job-timeout line does not block the match (one matching line classifies
the run), and a BARE timeout with no transport signature is still left
alone, since it can be a real regression. Both new signatures are pinned
in the test's per-signature loop, plus a case on #6506's real composite
annotation and a bare-timeout-is-not-rerun guard.

* fix(acp-bridge): field-level turn attribution merge and replayDegraded bridge test (#7458)

* fix(serve): skip bus epoch lookup for virtual subagent SSE streams (#7458)

The REST SSE route looked up the bus epoch for every session id, but
virtual subagent sessions ride their own bus and their compound ids are
not in the bridge's byId map, so the lookup threw and aborted the
subscription — breaking subagent event streams. Skip the lookup for the
virtual path and degrade a torn-down real session to a headerless stream
(mirrors the /acp route). Also bumps the daemon browser SDK bundle budget
(167KB -> 168KB) for the epoch fields and declares eventEpoch on
DaemonSession so the create/attach path drops its inline type cast.

* fix(serve): stamp eventEpoch on accepted continuations and surface replayDegraded in the SDK (#7458)

Address three review suggestions:
- POST /session/:id/continue now returns eventEpoch alongside lastEventId,
  mirroring the prompt 202 envelope so continuation-seeded SSE cursors
  detect daemon restarts (DAEMON-001)
- DaemonSessionClient exposes replayDegraded from the load response so SDK
  consumers can prefer the full transcript over a degraded snapshot
- add /acp dispatch-level regression test for the degraded-snapshot stderr
  breadcrumb (fires only when snapshot.degraded is set)

* test(cli): fix load-reply race in the degraded-breadcrumb transport test

Await each session/load reply frame before opening the session stream so
the GET cannot race conn.ownSession() into a 403; addresses the review
Critical on the deg-0 arm.

* fix(serve): allow and expose X-Qwen-Event-Epoch in CORS headers

Cross-origin SSE clients must send the epoch header through preflight and
read it from the response, or stale-cursor detection (DAEMON-001) is
silently disabled for every CORS client.

ChiGaoand秦奇 93af84f248 fix(cli): surface unhandled rejections and render errors instead of swallowing them (#7406)
* fix(cli): surface unhandled rejections and render errors instead of swallowing them

Unhandled promise rejections were emitted to AppEvent.LogError which has
no production listener, making crashes completely invisible in debug logs
and stderr. Additionally, the main App tree had no top-level
ErrorBoundary, so React render errors were caught only by Ink's internal
boundary which silently exits via exitPromise.catch(noop).

- Write unhandled rejection details to the debug logger so they appear
  in ~/.qwen/debug/<session>.txt
- Wrap the interactive UI tree in an ErrorBoundary that logs fatal
  render errors and shows a fallback message instead of silent exit

* fix(cli): address review feedback — normalize non-Error throws and add exit path

- Normalize non-Error thrown values (strings, null, etc.) to Error
  instances in ErrorBoundary before logging/rendering, preventing
  secondary TypeErrors from sanitizeTerminalText(undefined)
- Schedule a graceful exit (5s delay) from the fatal render error
  fallback so the session does not hang under the Kitty keyboard
  protocol where Ctrl+C is a keypress, not SIGINT

* test(cli): add test for non-Error thrown value normalization in ErrorBoundary

120218c883 fix(cli): insert newline on Shift+Enter and stop streaming thinking-block flicker (#7397)
* fix(cli): re-push Kitty keyboard flags onto the alternate screen in VP mode

In VP mode the app renders on the alternate screen (`alternateScreen: true`),
but the Kitty keyboard progressive-enhancement flags were pushed only once at
startup on the main screen. The Kitty spec tracks these flags per screen
buffer, so the alternate screen's stack stays empty and the terminal never
reports modifiers: Shift+Enter arrives as a bare Enter (submit) or, when the
terminal emits an ESC-prefixed variant, as an orphaned Escape that trips the
empty-buffer double-Esc rewind prompt — so Shift+Enter can never insert a
newline in VP mode even on Kitty-capable terminals (e.g. cmux).

Re-push the flags onto the alternate screen right after Ink enters it (Ink
writes the enter-alt-screen sequence synchronously inside render(), so the
push is correctly ordered). Ink discards the alternate screen and its flag
stack on unmount, leaving the startup main-screen push balanced by the
existing disableKittyProtocol() on cleanup.

* fix(cli): stabilize streaming thinking block height to stop flicker

The pending "Thinking…" block renders the tail of the reasoning stream in a
content-sized box. As the model emits paragraph separators, a blank line
enters and leaves the tail window (and `trimEnd` drops trailing blanks), so the
visible line count oscillates and the block flickers 2→3→5 rows during
streaming.

Track the tallest height the block has reached for the current thought and
never render fewer rows than that (capped at the streaming window size),
padding at the top so the newest line stays pinned to the bottom. The tracker
resets when streaming ends or when the buffer shrinks (a new thought replaced
it), so height is monotonic within a thought without leaking across thoughts.

* fix(cli): decode xterm modifyOtherKeys Shift/Ctrl/Alt+Enter so it inserts a newline

Terminals such as Ghostty report Shift+Enter as the xterm modifyOtherKeys
sequence `ESC [ 27 ; <mods> ; <key> ~` (e.g. `ESC [ 27 ; 2 ; 13 ~`) when the
Kitty keyboard protocol is not negotiated — which is the default, since Kitty
detection does not always succeed. Two bugs kept this from inserting a newline:

1. The CSI-u parser read the leading `27` marker as the key code (matching the
   Escape key code 27) instead of the real key code in the third parameter, so
   with Kitty enabled Shift+Enter was mistaken for Escape and tripped the
   double-Esc rewind prompt.
2. The reassembly path that stitches readline's shredded CSI fragments back
   together was gated behind `kittyProtocolEnabled`, so with Kitty disabled the
   `ESC [ 27 ; 2 ;` head plus the stray `13~` tail leaked into the composer as
   literal text and no newline was inserted.

Decode the third parameter as the real key code for the `27;…~` form, and route
those sequences through the reassembly buffer even when Kitty is off (only the
`ESC [ 27` marker opts in, so keys readline already parses cleanly are
untouched). Shift/Ctrl/Alt+Enter now insert a newline in both VP and non-VP
mode regardless of Kitty negotiation.

* fix(cli): anchor VP viewport to the top until a conversation turn exists

On a fresh VP-mode session the virtualized list holds the banner plus startup
notices (tips / MOTD / info), so it is longer than one item. Keying the initial
scroll anchor off list length alone selected scroll-to-end, which pinned the
banner to the bottom of the full-height viewport and left the top half of the
screen blank.

Anchor to the top until there is an actual conversation turn (a user/user_shell
history item or a pending response), then resume scroll-to-end so the latest
output stays in view. Startup notices no longer count as content that forces
bottom alignment.

* fix(cli): stabilize streaming thinking window against availableTerminalHeight drift

The grow-only streaming thinking window still flickered because its line cap was
derived from availableTerminalHeight. While a thought streams the terminal keeps
constrainHeight on, so availableTerminalHeight (and the derived maxLines) drifts
up and down as sibling pending content grows, and the grow-only clamp
`min(maxLines, …)` shrank the block whenever it dipped.

Use a constant window height (MAX_STREAMING_THINKING_VISUAL_LINES) for the
pending window instead. The window is only a few lines, so a fixed cap cannot
meaningfully overflow (VP scrolls anyway), and the height stays stable while
still growing monotonically within a thought.

The modifyOtherKeys prefix check ran on every keypress, but some synthetic

chaining so a missing sequence is simply not a modifyOtherKeys start.

8fb1f17c3f fix(cli): tighten VP-mode controls footprint and fix shell tool indicator overlap (#6931)
* fix(cli): fix VP-mode controls footprint, indicator overlap, transcript crash, and scroll clipping

VP mode is slated to become the default renderer. Several UX issues block that:

- Shell tool status indicator overlapped / sat flush against the command text: the indicator Box used minWidth without flexShrink, so Yoga could compress it below its reserved column when the flexGrow'd command sibling applied pressure. Add flexShrink={0} (mirrors ToolElapsedTime in the same row) and reserve 3 columns (glyph + two trailing spaces) so the tool name never sits flush against the glyph.
- Sticky todo panel + live agent panel together consumed the whole viewport, leaving no room for the conversation. In VP mode cap the sticky todo list to 2 items and the live agent panel to 3 rows, freeing ~3 extra rows for the conversation on a 24-row terminal. Introduce LIVE_AGENT_PANEL_VP_MAX_ROWS as the single source of truth for the VP panel row budget, referenced by both the layout (rendered maxRows) and the composer keyboard handler (its candidate window), so the two can't drift. Keep the AppContainer layout-key todo cap in lockstep with the rendered value.
- Ctrl+O transcript crashed ("useStreamingContext must be used within a StreamingContextProvider") whenever the frozen snapshot held a tool in the Executing state: TranscriptView renders as a sibling of <App/>, which owns the StreamingContext.Provider, so the transcript subtree had no provider and the executing tool's spinner threw. Wrap the TranscriptView branch in its own StreamingContext.Provider.
- VP viewport bottom was clipped during a pure streaming turn: the controls height is measured one frame late, and its measure effect's deps omitted the composer's own dynamic height inputs (streamingState, embeddedShellFocused, queued messages, input-area mount). With buffer/todo/agent all steady, the loading block appearing left controlsHeight too small and availableTerminalHeight too large until an unrelated dep re-triggered the measure. Add those deps (excluding the per-second elapsedTime / loading phrase, which don't change row count).

All rendering changes gate on useTerminalBuffer; non-VP rendering is unchanged.

* fix(cli): extract shared VP todo cap constant and fix test mock drift

Review feedback follow-up:

- Extract STICKY_TODO_VP_MAX_VISIBLE_ITEMS (= 2) in todoSnapshot.ts
  and add getStickyTodoMaxVisibleItemsForMode() as single source of
  truth for both DefaultAppLayout (render) and AppContainer (layout
  key), preventing silent drift between the two sites.
- CompactToolGroupDisplay.test.tsx mock now uses importOriginal() to
  keep STATUS_INDICATOR_WIDTH in sync with production.
- Add tests for getStickyTodoMaxVisibleItemsForMode (VP cap, non-VP
  passthrough, floor behavior).
- Update PR body to accurately describe which changes are VP-gated
  vs. apply to both renderers.

* fix(cli): migrate ScreenReaderAppLayout to shared VP todo cap

ScreenReaderAppLayout still called getStickyTodoMaxVisibleItems directly,
missing the VP-mode cap. VP + screen-reader is a reachable combination,
so migrate to getStickyTodoMaxVisibleItemsForMode for consistency.

* fix(cli): make VP panel caps height-aware instead of hardcoded

Replace static VP-mode caps with height-aware functions:

- Sticky todo panel: was flat 2 rows, now clamp(floor(h/12), 2, 4).
  Short terminals (<=24 rows) still get 2; tall ones (>=48) get up to 4.
- Live agent panel: was flat 3 rows, now clamp(floor(h/10), 3, 5).
  Short terminals (<=30 rows) still get 3; tall ones (>=50) get up to 5.

Both caps stay in lockstep between render and keyboard-nav sites via
the same shared functions (getStickyTodoMaxVisibleItemsForMode and
getLiveAgentPanelVpMaxRows).

* fix(cli): allow Shift+Enter for newline in VP mode input box

Two key bindings intercepted Shift+Enter before BaseTextInput's NEWLINE
handler could run:

1. ACCEPT_SUGGESTION's return binding lacked shift: false, so Shift+Enter
   was captured as 'accept completion suggestion' whenever the slash-command
   or @-file completion dropdown was visible. Added shift: false.

2. The isPerfectMatch check used Command.RETURN (no modifier constraints)
   instead of Command.SUBMIT (which requires shift: false), causing
   Shift+Enter to submit when the buffer exactly matched a slash command.
   Changed to Command.SUBMIT.

* test(cli): add unit tests for getLiveAgentPanelVpMaxRows

Cover min rows on short terminals, growth with height, max cap on
tall terminals, and invalid height fallback.

* test(cli): sync keyMatchers.test.ts with ACCEPT_SUGGESTION shift: false

1. Fix stale originalMatchers reference to include !key.shift
2. Add createKey('return', { shift: true }) as negative test case

401170d488 feat(cli): mouse text selection and copy in VP mode (#6937)
* docs(cli): design for VP mode mouse text selection and copy

First step of the VP mouse-selection feature: the design doc, submitted
ahead of implementation so the approach can be reviewed before code lands.

Proposes an application-level selection and copy system for VP mode, where
SGR mouse tracking currently suppresses native terminal selection. Evaluates
two routes and commits to exposing the Ink renderer cell grid via the
existing Ink patch, which makes coordinate-to-text mapping uniform across all
content types. Implementation follows as staged milestones on this branch.

* docs(cli): revise VP selection design per feasibility audit

Rework the design after the implementation-feasibility audit against the
Ink 7 renderer source. Key corrections and scope changes:

- Two-PR plan. PR 1 (this branch) delivers the Ink frame-buffer foundation
  and a visible-region visual-selection MVP (visual-cell copy, clear on
  scroll). PR 2 adds cross-screen selection and semantic copy fidelity
  (soft-wrap rejoin, gutter exclusion), which need renderer semantic metadata.
- Highlight goes through a bidirectional frame controller with a
  pre-serialization transform and throttled repaint; the earlier read-only
  accessor plus post-commit callback could not highlight the current frame.
- Immutable cell/style allocation to avoid leaking the highlight onto other
  on-screen occurrences of the same text via shared cached styled chars.
- Corrected coordinate formula (frame is not unconditionally top-anchored),
  OSC 52 behavior (over-cap skips and returns false; surface a copy failure),
  and the note that release already has non-selection consumers.
- Merge gate and milestones aligned to the two-PR split.

* feat(cli): M0 Ink frame-buffer controller for VP text selection

First implementation milestone of VP-mode mouse text selection: the Ink
frame-buffer foundation and its read-side wrapper, with the design's M0
go/no-go criteria proven by tests.

Extend the Ink patch into a small bidirectional frame controller. The
renderer now retains the composited cell grid, applies a selection-range
background highlight before serialization (allocating new cells so the
shared cached styled chars are never mutated), and publishes an immutable
frame each render. setSelection deduplicates and schedules exactly one
repaint through Ink's own throttle; getFrameController(stdout) exposes the
bridge to the application.

Add ScreenBuffer, the read-side wrapper the selection state machine (M1)
will build on: getCellAt / lineText / dimensions plus setSelection and
subscribe. Tests cover addressable cells, wide-character spacer handling,
pre-serialization highlight and clear, no highlight leakage onto identical
on-screen text, and single-frame-per-change dedup (no render loop).

The package.json export additions from the existing patch are preserved.

* feat(cli): M1 mouse text selection with live highlight in VP mode

Turn mouse press/drag/release in the VP history viewport into a text
selection, highlighted live and copied on release.

- SelectionState: anchor/focus model in composited-frame coordinates,
  normalized to reading order, with collapsed/empty queries.
- selection-text: extract the visual text of a range, emitting a wide glyph
  once (skipping its spacer) and trimming per-line trailing padding. B1
  fidelity — visual cells as shown; soft-wrap rejoin and gutter exclusion
  are PR 2.
- selection-coords: map a terminal cell to frame grid coordinates via the
  frame anchor (bottom-pinned on overflow), plus viewport bounds/clamp.
- TextSelectionController: headless controller that subscribes button-level
  mouse events, drives the state machine, highlights the range through the
  frame controller (setSelection), and copies on release. Ignores the
  scrollbar column and presses outside the viewport; clears on any scroll
  (visible-region only in B1).
- VirtualizedList/ScrollableList expose getViewportRect(); MainContent mounts
  the controller in the VP branch.

Copy-failure feedback, key preemption (Esc/Ctrl+Shift+C), streaming/resize
invalidation, and word/line selection follow in M3/M4.

* feat(cli): gate VP text selection behind ui.textSelection settings

Add ui.textSelection.enabled (default true) and ui.textSelection.copyOnSelect
(default true) and wire them into the selection controller: selection is only
active when enabled, and release copies only when copyOnSelect is on. Disabling
enabled leaves the mouse to the terminal for those who prefer it.

* feat(cli): M4 word/line select, selection invalidation, and docs

- Double-click selects a word, triple-click selects a line, driven by a
  multi-click detector in the controller; word/line spans come from the
  composited frame (non-whitespace run / first-to-last-content cell) and are
  copied on select.
- Invalidate the selection when the content scrolls, streams (scrollHeight
  changes), or the terminal resizes (frame height changes / resize event),
  detected via a frame subscription with a baseline captured at selection
  start. Our own highlight renders leave those unchanged, so there is no
  render loop.
- Document mouse selection in the keyboard-shortcuts reference and the
  ui.textSelection settings in the settings reference; refresh the
  useTerminalBuffer description and regenerate the IDE settings schema.

A single click already clears a selection, so Esc-to-clear, the manual
copy keybinding, the footer "copied" toast, and a drag discoverability hint
are deferred follow-ups within this PR.

* fix(cli): drop redundant resize listener in selection controller

Real-terminal testing surfaced a MaxListenersExceededWarning (11 resize
listeners) on startup: the selection controller added a stdout 'resize'
listener on top of the existing ones. A resize reflows content, which changes
the frame/scroll height already watched by the frame subscription, so the
explicit listener was redundant. Remove it to stay under the max-listeners
cap; invalidation on resize still works via the subscription.

* fix(cli): close VP selection review gaps

* refactor(cli): make VP text selection unconditional

* fix(cli): make VP mouse selection usable

* fix(cli): preserve selection in thought blocks

* fix(cli): use layoutRowForEvent in ClickableThinkMessage hit-test

The click-to-expand handler on collapsed thought blocks used a bare
`event.row - 1` for coordinate mapping.  When the ink frame exceeds
the terminal height (e.g. ShowMoreLines renders an extra row), the
frame anchor becomes negative and the naive mapping always misses the
1-row-tall collapsed thought.

Adopt the same layoutRowForEvent helper that RowMouseController uses,
which correctly accounts for the frame anchor offset.

Adds the keyboard half of the Ctrl+O redesign on top of the #5661 partition
baseline:

- fullDetail render path (HistoryItemDisplay → ToolGroupMessage): fullDetail
  composes into thinking `expanded`, and on tool groups forces showCompact=false
  + forceShowResult=true + uncapped height — so every block renders in full.
- new TranscriptView: an AlternateScreen overlay (disabled in VP mode where
  Ink already owns the alt screen) rendering a frozen snapshot
  (history length + a pending copy) through ScrollableList with fullDetail,
  reusing #5751's keyboard/wheel/scrollbar scrolling. Adaptive
  estimatedItemHeight for the taller full-detail rows.
- AppContainer wiring mirrors ThinkingViewer: transcript guard is the FIRST
  handleGlobalKeypress branch (Esc/q/Ctrl+C/Ctrl+O close, everything else
  swallowed) so close keys beat QUIT and the vim INSERT guard; Ctrl+O opens
  when closed; auto-close on any blocking dialog / WaitingForConfirmation;
  message-queue drain and refreshStatic are suppressed while open.
- Command.TOGGLE_TRANSCRIPT bound to Ctrl+O.

* fix(tui): repaint normal buffer when transcript closes (no duplicate scrollback)

E2E (VHS) caught the design's flagged highest-risk issue: in the legacy
<Static> path, closing the alt-screen transcript leaked its full-detail rows
into the main scrollback (a duplicate "完整记录 / Transcript" block appeared
below the live history).

Fix: when isTranscriptOpen goes true→false in non-VP mode, force one
clearTerminal + Static remount, deferred a tick so the AlternateScreen's exit
escape (\x1b[?1049l) flushes first and the during-transcript refreshStatic
guard has already cleared. VP mode keeps its own scrollback via the React tree
and is unaffected.

Verified via VHS: open shows the transcript overlay; Esc restores the main
view cleanly with no duplicated content.

* docs(tui): rebase ctrl-o design doc to #5661's type-based partition

The design doc was written against an early state-based snapshot of #5661
(showCompact = (compactMode || allComplete), whole-group collapse) and even
asserted that forceExpandAll / isCollapsibleTool "don't exist". The merged
#5661 is type-based partition and those symbols are its core. Rewrite the
affected sections to match the shipped baseline:

- §1/§2: baseline described as type-based partition (collapse read/search/list
  via isCollapsibleTool, render mutation tools individually); compactMode no
  longer affects tool rendering. Added a revision note.
- §3.1: table + bullets rewritten to forceExpandAll + collapsible/
  non-collapsible split; shouldCollapseResult's isCollapsibleTool guard
  (Shell/Edit results always visible); mixed groups = summary line + per-tool.
- §4.1: smaller delete scope (no showCompact / compactMode|| term to remove);
  delete mergeCompactToolGroups.ts; keep web-shell ui.compactMode passthrough.
- §4.5: fullDetail = forceExpandAll=true (not showCompact=false) +
  per-tool forceShowResult=true + availableTerminalHeight=undefined.
- §4.8/§5/§7/§8/§9/appendix: symbols/forensics corrected to the real merged

full-detail mode those groups were therefore NOT fully expanded.

Guard both early returns with `!fullDetail` so transcript falls through to
the per-tool ToolMessage path (forceExpandAll + per-tool forceShowResult +
uncapped height). Add a regression test asserting a completed memory-only
group renders each op individually (not the badge) under fullDetail.

  (config.ts:1532), so non-TTY rarely mounts; the only edge is `-i`.
  Decision: add a process.stdout.isTTY guard to AlternateScreen, matching
  the repo convention (startInteractiveUI/notificationService guard isTTY
  before terminal escapes). Doc now marks it "to implement" + test.

- Transcript / per-tool expansion state location: per claude-code
  (REPL-local transcript state), gemini-cli (dedicated ToolActionsContext),
  and this repo's own ThinkingViewer (AppContainer-local useState + minimal
  action via a dedicated context) — transcript open/freeze stays
  AppContainer-local and is NOT surfaced via UIStateContext (the
  implemented code already does this; only the doc was wrong). Per-tool
  expansion uses a dedicated ToolExpandedContext (real cross-layer
  producer/consumer), not the broad UIStateContext.

Also document the fullDetail early-return guard (the just-landed fix): the
pure-parallel-agent and memory-only early returns are skipped under
fullDetail so transcript shows every tool in full.

* docs(tui): align design doc status/scope with current PR (audit follow-up)

Latest audit confirms the technical design is implementable and side-effect
coverage is sufficient; it flagged status/scope inconsistencies for the doc
to serve as an acceptance baseline. Fixes:

1. Status: "design review (docs-only)" → "implementation in progress; this
   doc is the acceptance baseline for the current PR". Added an
   implemented-vs-pending status table.
2. Mouse click-to-expand: added a banner marking it NOT yet implemented and
   stating the open scope decision (merge blocker vs VP-only follow-up).
3. #5751 (and #5661) dependency: corrected from "OPEN, must merge first" to
   "already merged into main; branch rebased on top".
4. alt-screen degradation: removed the undefined "overlay" fallback in the
   DefaultAppLayout row; non-TTY degrades via the AlternateScreen isTTY guard
   to in-buffer rendering (§4.2), no separate overlay path.
5. Fixed a broken bold marker (`\*\*`) in the AppContainer row.

* docs(tui): scope mouse click-to-expand out as a follow-up

Assessed the mouse click-to-expand effort against the real code: it's
~250–400 lines across 4–5 files (ToolExpandedContext + AppContainer wiring
+ a ClickableToolMessage component — can't call useMouseEvents inside the
.map() — + ToolGroupMessage wiring + mouse hit-test tests). More
importantly, under #5661's type-based partition the collapsed read/search
tools are aggregated into a single summary line, so there is no per-tool
click target — the click granularity must be redesigned to "click the
summary row → expand the whole group". Plus the known SGR-mouse vs native
text-selection risk.

Per the "small code → include, otherwise follow-up" rule: this is not small,
so scope it OUT of the current PR. The current PR delivers Ctrl+O transcript
only. Marked §1 goal #4, §4.8 (banner + draft), §9 commit 4, and the status
table accordingly; the §4.8 design is kept as a draft for the follow-up PR.

- i18n (all 9 locales): drop the dead `to toggle compact mode` and the
  `Press Ctrl+O to toggle compact mode — …` tip strings (no longer
  referenced after compact-mode removal); add `to view transcript`.

* docs(ctrl-o): design §4.9 — full tool detail passthrough in transcript

Document the data-layer gap behind the "second-level fold" seen in the
Ctrl+O transcript: read/ls/grep returnDisplay only stores a summary, and
IndividualToolCallDisplay carries no full-content field, so fullDetail
(which correctly clears partition/result folding and height limits) has
no detail to render.

Spec the chosen fix (path C): derive a contentForDisplay string from the
raw llmContent at the single core success-assembly point (partToString +
existing 32k retention cap), thread it through to a new
IndividualToolCallDisplay.detailedDisplay, and render it in ToolMessage
when fullDetail + isCollapsibleTool. Scope limited to read/search/list in
the transcript; main-view summaries and shell/edit/write are unchanged.

* docs(ctrl-o): adopt plan Y for §4.9 and address transcript-detail audit

Address the audit on §4.9 (full tool detail in the Ctrl+O transcript):

- Rewrite §4.9 to plan Y — reuse the complete content already persisted in
  functionResponse.response.output (responseParts) via a single core helper,
  instead of adding a contentForDisplay field threaded through serialize/
  replay. Saved/replayed transcripts get full detail for free (audit #6).
- Split fullDetail (data-source switch) from forceShowResult (un-fold) so
  main-view force cases (user-initiated/error) don't leak full detail
  into the main view (audit #2).
- Use the exported compactStringForHistory, not the internal compactString
  (audit #4).
- Scope by isCollapsibleTool incl. glob, not a hardcoded read/ls/grep list
  (audit #5).
- §3.4: stop claiming the screenshot already shows full output; add a
  pre-§4.9 caveat and a merge-blocker row in the status table (audit #1).

* docs(ctrl-o): tighten §4.9 per second audit (no 2nd truncation, nested media, plan-Y guard)

- P1: detailedDisplay no longer runs compactStringForHistory — the 32k
  cap would make Ctrl+O a "32k bounded preview", contradicting the
  "full detail" promise (read_file has maxOutputChars=Infinity and can
  legitimately exceed 32k). Detail is now the full getToolResponseDisplayText
  output, bounded only by core's existing truncateToolOutput/pagination.
- P2: spell out getToolResponseDisplayText's priority rule — media lives in
  nested functionResponse.parts (not top-level); read response.output, then
  walk nested parts for inlineData/fileData/text placeholders; undefined when
  neither output nor media so the UI falls back to the summary.
- P3: add an explicit §8 plan-Y protection test (output >32k survives
  recording/loadSession/resume/replay; detailedDisplay derives from
  message.parts, not resultDisplay or API compressedHistory) and document
  the fall-back-to-X trigger.

* feat(ctrl-o)!: §4.9 full tool-detail passthrough in transcript

Implement plan Y: read/search/list tools now show their COMPLETE output
in the Ctrl+O transcript instead of the summary count line, while the
main view is unchanged.

- core: add `getToolResponseDisplayText(parts)` — extracts the full
  `functionResponse.response.output` (skipping the non-informative
  "Tool execution succeeded." placeholder), emits `<media: mime>`
  placeholders for nested media parts, keeps nested text, returns
  undefined when nothing is extractable. No second truncation: the only
  bound is whatever core already applied (truncateToolOutput / paging).
- cli: add derived (non-persisted) `IndividualToolCallDisplay.detailedDisplay`.
  Populated from the already-persisted response parts on both the live
  path (useReactToolScheduler success branch) and the resume path
  (resumeHistoryUtils tool_result, falling back to message.parts for
  older records).
- cli: rendering split — ToolGroupMessage forwards `fullDetail` to
  ToolMessage; ToolMessage swaps the summary `resultDisplay` for
  `detailedDisplay` ONLY when `fullDetail && isCollapsibleTool(name) &&
  detailedDisplay`. Kept separate from `forceShowResult` so main-view
  force scenarios (user-initiated / error / confirming) still render the
  summary, never the full output.
- ACP path needs no change: ToolCallEmitter.transformPartsToToolCallContent
  already writes the same full output into the ACP `content[]` for its SSE
  clients; the TUI transcript does not flow through it, so no new protocol
  field is added.

Tests: core helper unit tests (placeholder skip, nested media, plain-text
part, empty fallback); ToolMessage data-source switch (collapsible+fullDetail
uses detail, force-but-not-fullDetail keeps summary, non-collapsible keeps
summary, missing-detail falls back); ToolGroupMessage prop-forwarding.

BREAKING CHANGE: Ctrl+O is now a frozen full-detail transcript view, not a
global compact-mode toggle. The `TOGGLE_COMPACT_MODE` command and the TUI
effect of `ui.compactMode` / `ui.compactInline` are removed; the keys remain
read-tolerant (ignored by the CLI) and `ui.compactMode` is still forwarded to
the web shell. See docs/design/ctrl-o-detail-expand/design.md §6 for migration.

* fix(ctrl-o): address review — repaint race, suppressOnRestore parity, transcript error logging

- AppContainer: fix close-repaint setTimeout being cancelled by streaming

  the pending repaint — leaving stale pre-transcript content in the legacy
  <Static> normal buffer. Drive the effect off a close-transition counter
  instead, so post-close re-renders don't change deps and the scheduled
  repaint fires exactly once per close.

  `!display.suppressOnRestore` filter, so items collapsed on session resume
  (ui.history.collapseOnResume) are not re-exposed in the Ctrl+O view.

* fix(ctrl-o): address review — plain-text detail, shared placeholder const, resume status guard, scroll hint

Four review fixes on the §4.9 transcript work:

- ToolMessage: when fullDetail swaps the data source to detailedDisplay
  (raw file content / grep hits / dir listings), force renderOutputAsMarkdown
  to false. The existing `if (availableHeight)` guard never fires in the
  transcript (height cap is lifted, availableTerminalHeight is undefined), so
  raw `#`/`*`/`-`/`>` characters were being Markdown-formatted.
- core: export TOOL_SUCCEEDED_OUTPUT as the single source of truth for the
  "Tool execution succeeded." placeholder. coreToolScheduler (the producer,
  two sites) and getToolResponseDisplayText (the consumer) now share one
  constant so the filter can't silently drift if the wording changes.
- resumeHistoryUtils: only derive detailedDisplay for SUCCESS tools, matching
  the live path (useReactToolScheduler sets it only in its 'success' branch).
  Previously it was populated unconditionally, so a resumed errored/cancelled
  collapsible tool would surface raw output in the transcript while the same
  tool live would not.
- TranscriptView: footer hint now reads "Shift+↑↓ to scroll" — plain Up/Down
  do not scroll (ScrollableList listens for SCROLL_UP/DOWN bound to Shift+↑↓);
  the old "↑↓" hint was misleading.

Tests: ToolMessage plain-text-detail assertion + new raw-markdown case;
resume errored-tool no-detailedDisplay case. typecheck/lint/tests green
(core scheduler 222, cli suites pass).

* fix(tui): guard transcript non-TTY output + clear detailedDisplay on compaction

Addresses three review findings on the Ctrl+O transcript work:

- Non-TTY byte leak: `useMouseEvents` enabled SGR mouse mode (?1002h ?1006h)
  whenever stdin supported raw mode, ignoring stdout. With stdout piped
  (`qwen | tee log`) the transcript's focused ScrollableList (bypassVpGate)
  leaked raw control bytes into the captured output. Gate the enable on
  `stdout.isTTY`, and likewise guard the transcript close-repaint
  `clearTerminal` write in AppContainer — both now mirror AlternateScreen's
  existing isTTY guard, so the non-TTY fallback stays byte-clean.

- Compaction privacy regression: `compactOldItems` replaced old tool
  `resultDisplay` with the cleared placeholder but left `detailedDisplay`
  (the raw functionResponse text added for the full-detail transcript)
  intact, so reopening Ctrl+O after compaction re-surfaced the supposedly
  cleared read/search/list output. Clear `detailedDisplay` wherever
  `resultDisplay` is cleared, with a regression test.

- Docs: keyboard-shortcuts.md still described Ctrl+O as "toggle compact
  mode"; updated to the open/close full-detail transcript behavior.

* fix(tui): address Ctrl+O transcript review — q-guard, callback churn, tests, cleanup

Resolves the qwen3.7-max /review findings:

- Modifier guard on the transcript close key: bare `q` closed the
  transcript, but Ink reports Ctrl/Alt/Shift+Q as `{ name: 'q', … }` too
  (Alt arrives as `meta`), so those silently closed it. Guard
  `!key.ctrl && !key.meta && !key.shift` (Shift+Q is a literal `Q`).

- Stable `openTranscript`: it captured `historyManager.history` and
  `pendingHistoryItems` as deps, both of which change identity every
  streaming tick, rebuilding the callback — and the whole
  `handleGlobalKeypress` closure that lists it — on every render during
  streaming. Read both via refs so the callback is referentially stable.

- AppContainer transcript integration tests (the removed TOGGLE_COMPACT
  tests had no replacement): Ctrl+O installs TranscriptView; Esc / q /
  Ctrl+C / Ctrl+D close it; Ctrl+Q / Alt+Q / Shift+Q do NOT (modifier
  guard); arbitrary keys are swallowed and keep it open; a blocking
  confirmation (WaitingForConfirmation) auto-closes it (anti-deadlock).

- Dead i18n string: removed the orphaned
  'Press Ctrl+O to show full tool output' key from all 9 locale files
  (no `t()` reference remained after the compact-mode sweep).

- Design doc: replaced the leaked absolute worktree path with a
  placeholder, and corrected the §6 keybinding-migration note — the
  codebase has no user-configurable keybinding override surface
  (`keyMatchers` always uses hardcoded defaults), so there is no
  persisted `toggleCompactMode` binding to migrate; the startup-detection
  step is not applicable until such a feature exists.

* fix(tui): escape ANSI in transcript detailedDisplay + gate its extraction

Two findings from the qwen3.7-max /review on §4.9:

- [Critical] ANSI escape injection: `detailedDisplay` carries raw,
  un-sanitized tool output (file contents, grep hits, directory
  listings). The Ctrl+O transcript rendered it straight to <Text>
  without escaping, so a malicious repo file with embedded terminal
  control sequences (e.g. `\x1b[?1049l` to drop the alt-screen, OSC 52
  for clipboard poisoning) would execute when the transcript opened —
  and fullDetail lifts the height cap, exposing the whole file. Run it
  through `escapeAnsiCtrlCodes` (already used for agent names in this
  file) before rendering. Added a regression test asserting the raw ESC
  bytes don't survive.

- [perf] `detailedDisplay` was extracted on every successful tool call
  (~25K chars from core's truncation) but is consumed only by the
  transcript's fullDetail render for collapsible (read/search/list)
  tools. Gate the extraction on `isCollapsibleTool(displayName)` so
  edit/write/command/agent calls no longer store a large string the
  renderer never reads — mirrors ToolMessage's `usingDetailedDisplay`
  gate (which also keys off the display name).

* fix(tui): gate resume-path detailedDisplay on isCollapsibleTool (match live path)

The resume path (resumeHistoryUtils.ts) extracted `detailedDisplay` for
every successful tool call, unlike the live path in useReactToolScheduler
which gates on `isCollapsibleTool(displayName)`. Since the transcript's
`usingDetailedDisplay` only consumes it for collapsible (read/search/list)
tools, resuming a session with many edit/write/command/agent calls stored
large (~25K char) strings the renderer never reads. Apply the same gate so
live and resume stay consistent, using `toolCall.name` (the display name,
set from `tool.displayName`) to match the renderer's key.

Updated the existing derivation tests to use a collapsible read tool (an
edit tool now correctly yields undefined) and added a regression asserting
a non-collapsible tool leaves detailedDisplay undefined on resume.

* fix(tui): strip bare C0 control bytes from transcript detailedDisplay + memoize

Follow-up to the ANSI-escape fix. `escapeAnsiCtrlCodes` delegates to
ansi-regex, which only matches ESC-prefixed sequences, so bare C0 control
bytes without an ESC prefix (BEL \x07, BS \x08, FF \x0c, SO \x0e, SI \x0f,
CR, …) passed through to <Text> and could still corrupt the display or
ring the bell from a malicious file's contents. Add a second pass that
strips those bytes (keeping only TAB and LF, which structure multi-line
output). Memoize the two-pass sanitization with useMemo keyed on
detailedDisplay so the ~25K-char regex work doesn't re-run every render.

Extended the ToolMessage regression test to assert bare C0 bytes are
stripped alongside the ESC sequences.

* test(tui): memoize HistoryItemDisplay, add ErrorBoundary tests + TAB/LF invariant

Addresses three review suggestions:

- Wrap `HistoryItemDisplay` in `React.memo` so the Ctrl+O transcript
  (which re-renders on every scroll tick) skips re-rendering
  frozen-snapshot items whose props are shallowly unchanged. The
  transcript passes stable `item` references, so the default shallow
  compare is effective; harmless for the main view (items live in
  `<Static>` and render once).

- Add ErrorBoundary.test.tsx covering the four behaviors: renders
  children when healthy, catches a render error into the default
  fallback with the message, renders a custom fallback, calls `onError`
  with the error + component stack, and `reset` clears the error state so
  the subtree recovers.

- Lock the C0-strip invariant: assert TAB and LF survive in
  detailedDisplay (the regex intentionally skips \x09/\x0a) so a future
  regex change can't silently collapse multi-line/columnar output.

  imports and the `onClose` call-site + props.

  renders the recovery fallback, not a crash); add live-path

  extracted, non-collapsible → undefined); add Ctrl+O to the transcript
  close-keys it.each (the toggle key was the only close key untested).

* fix(tui): harden compaction guard to always clear detailedDisplay

The compaction cleanup only cleared `detailedDisplay` inside the
`resultDisplay != null` branch (both the group-level trigger, the

`detailedDisplay` (no resultDisplay) would skip compaction and leave the
raw transcript detail intact — a latent privacy leak if the two fields

  a plain English string (last-resort message for callers with no

* fix(tui): share terminal-sanitize pipeline; guard AlternateScreen writes

- Extract the three-pass sanitizer (ANSI escape + bare-C0 strip + bidi
  strip) into `sanitizeTerminalText` in textUtils.ts as the single source
  of truth, and use it at all raw-text render sites: ToolMessage's
  `detailedDisplay`, and the TranscriptView + ErrorBoundary error-message
  fallbacks (previously those only escaped ANSI, missing C0/bidi — the
  boundary catches errors from the fullDetail path that processes raw tool
  output, so a crafted item shape could carry unsanitized bytes into
  error.message). Removes the duplicated regex consts from ToolMessage.

- AlternateScreen: wrap the alt-screen escape writes (and the exit/cleanup
  writes) in try/catch so a synchronous stdout error (EPIPE on terminal
  close, EAGAIN under backpressure) can't propagate uncaught from the
  effect and crash the app or corrupt the terminal.

c62b34433d feat(cli): VP mode — inline thought expand on click + auto-hiding scrollbar (#6079)
* feat(cli): VP mode — inline thought expand on click + auto-hiding scrollbar

Two VP-mode (ui.useTerminalBuffer) UX improvements:

1. Thinking: clicking a thought now expands it inline, in place, instead of
   opening a full-screen modal. The expanded thought becomes part of the
   conversation and scrolls with it, matching the lighter inline pattern.
   A thought spans the `gemini_thought` head plus its trailing
   `gemini_thought_content` continuations, so expansion is keyed by the head
   id (buildThoughtHeadIdMap) and one click expands/collapses the whole group.
   Alt+T still toggles all thoughts at once.

   The full-screen ThinkingViewer modal (and its context) is removed: it only
   ever opened in VP, where an inline-expanded thought is already scrollable
   via the viewport, so it was redundant. Drops ThinkingViewer.tsx,
   ThinkingViewerContext.tsx, and the now-dead thinkingFullText plumbing.

2. Scrollbar: the VP scrollbar now auto-hides — it renders as blank cells while
   idle (keeping width 1 so the viewport never reflows) and pops in only while
   scrolling, then fades out. Adds `ui.showScrollbar` (default true) to hide it
   entirely.

* feat(cli): advertise click in the collapsed thought hint (VP only)

The collapsed thinking line only hinted "option+t to expand", so the new
click-to-expand affordance was undiscoverable. Show "(click or option+t to
expand)" when the click handler is actually active — i.e. VP mode
(ui.useTerminalBuffer) — and keep the plain "(option+t to expand)" in non-VP,
where clicking does nothing (native scrollback is preserved).

8d5e47a07a fix(cli): clip live markdown to the viewport to stop non-VP scrollback replay (#6081)
* fix(cli): clip live markdown to the viewport to stop non-VP scrollback replay

In non-VP (default) mode the committed transcript lives in ink's `<Static>`
region; only the live/pending items form the dynamic frame. A long streaming
assistant message rendered ALL of its lines (code blocks self-truncate, but
plain prose / lists / tables had no overall cap), so the dynamic frame grew past
the terminal height. Once that happens ink takes its overflow path and writes
`clearTerminal + the entire static transcript + output` on EVERY repaint — i.e.
it re-streams the whole conversation on every streamed token. Focused, this is
continuous flicker; in a terminal multiplexer (tmux/cmux) the backgrounded tab
keeps doing it, so switching back replays the transcript top→bottom for a while.

Bound the pending markdown to `availableTerminalHeight` with
`maxHeight` + `overflow="hidden"`, which clips only when the content is genuinely
too tall (short messages render unpadded) and keeps the dynamic frame within the
viewport so the overflow path never fires. The full message still renders
uncapped once it commits to `<Static>`. Only applies while pending and when a
budget is known (constrainHeight on, non-VP).

Verified end-to-end with a stdout hook on the real built CLI in cmux: a long
streaming response emitted 239 full-transcript replays/7s before, 0 after.

* fix(cli): clamp total pending region height as a viewport backstop

The per-message clip caps each pending markdown message, but the non-VP pending
region renders MULTIPLE items and each is capped individually — several tall
pending items (a long thought + a long reply, or a reply + a tool group) can
still sum past the terminal height and re-trigger the clearTerminal +
full-transcript replay. Wrap the whole pending list in a maxHeight +
overflow="hidden" box (only while constrainHeight is on) so the total dynamic
frame can never exceed the viewport, regardless of how many/what pending items.

overflow keeps the most recent rows (the tail), so interactive prompts / the
embedded shell — which live at the bottom — stay visible and only the oldest
rows are dropped; ShowMoreLines (Ctrl+S) still reveals the rest. The committed
transcript in <Static> is unaffected.

* fix(cli): guard pending backstop maxHeight against undefined terminal height

availableTerminalHeight is typed number | undefined; Math.max(1, ...) needs a

constrainHeight is on); otherwise render unclamped. No behaviour change when a
budget exists.

* revert(cli): drop aggregate pending-height backstop; keep per-item markdown clip

The MainContent-level maxHeight/overflow wrapper (added to bound the total
pending height) had real defects surfaced in review: ink's overflow clips the
NEWEST content rather than the oldest (so the active reply / interactive prompt
would be hidden), the outer wrapper does not register with OverflowContext so
ShowMoreLines' "Ctrl+S" hint is lost when it is the sole clipper, and it adds a
row beyond the budget via the sibling ShowMoreLines. It also targeted a
multi-item "sum" overflow that was never reproduced. Revert it. The per-item
markdown clip in MarkdownDisplay — verified end-to-end to stop the replay for
the reported case — remains. A correct aggregate backstop would need MaxSizedBox
with overflowDirection="top" and is left as a follow-up if the sum case is
confirmed.

* test(cli): assert content in clip tests + committed control; fix VP comment

Address review on the pending markdown clip:
- the clip tests asserted only line count; a blanked output would pass
  (''.split('\n').length === 1). Assert real content — /line \d+/ for the
  clipped case (clip direction is not asserted, only that it is non-blank) and
  the exact text for the short case.
- add a control test that a long COMMITTED (isPending=false) message renders in
  full, guarding the isPending gate.
- the clip also applies to VP pending items (both MainContent paths pass
  availableTerminalHeight when constrainHeight), so correct the "non-VP" note.

* fix(cli): head-slice live markdown instead of decimating overflow clip

The previous maxHeight + overflow="hidden" clip DECIMATES — ink drops
interspersed rows to fit, so a clipped streaming message rendered garbled
(non-contiguous) lines and could erase a code block's own "generating more"
indicator (its budget was uncoordinated with the outer clip). Confirmed with the
real component: a 30-line message at budget 8 rendered L01,L05,L09,... instead of
a clean head.

Slice the source lines to a CONTIGUOUS head that fits availableTerminalHeight
(reserving one row) and append a single "… generating more …" cue. Output is now
readable and contiguous; code blocks retained in the head keep their own
truncation. Short/committed messages are unchanged. Strengthen the test to assert
contiguous head + cue (locks against a regression back to decimation).

* test(cli): polish live-markdown clip cue, decouple floor const, add fence test

Address review on the head-slice:
- the "generating more" cue now uses ASCII ellipses (matching the file's other
  truncation cues) and wrap="truncate", so it stays one row on narrow terminals
  (the budget reserves exactly one row for it).
- decouple the pending budget floor from MaxSizedBox's MINIMUM_MAX_HEIGHT via a
  local MIN_PENDING_CONTENT_LINES (same numeric result, explicit intent).
- add a test for a code fence spanning the clip boundary (the EOF inCodeBlock
  flush path).

* test(cli): cover pending-clip edge cases (undefined budget, floor, single cue)

Address maintainer review:

  and a degenerate budget of 1 (Math.max floor keeps one content line + cue).
- assert the short-message case emits no "generating more" cue.
- assert the code-fence-boundary case emits at most ONE cue: the head-slice
  bounds code content to <= availableTerminalHeight - 2 (RenderCodeBlock's own
  inner budget), so the inner truncation never fires inside a slice — no stacked
  double indicator.

* fix(cli): reserve 2 rows in live-markdown clip to avoid a stacked double cue

RenderMathBlock reserves RESERVED_LINES=3 (vs code block's 2), so at the head
slice boundary a retained math block could hit its own inner "generating more"
cue on top of the outer one (confirmed: a $$-fenced pending message emitted two
cues). Reserve 2 rows in the head-slice budget (1 for the outer cue + 1 for the
widest inner reservation) so no retained block's inner truncation fires within
the slice. Add a math-block regression test asserting a single cue, and fix two
stale test comments that still referenced the old maxHeight/overflow approach.

* fix(daemon): resolve acp permission votes across connections

* fix(daemon): address review on acp permission vote resolution

Resolve the review feedback on PR #5912:

- dispatch.ts session/permission: add server-side stderr logging to every
  failure mode (missing requestId, no pending entry, ownership failure,
  bridge rejection) so a stuck permission prompt is debuggable, matching the
  legacy resolveClientResponse path.
- On bridge rejection (accepted === false), stop deleting the pending entry
  and stop reusing the "no pending" error. Keep the entry until teardown (as
  the legacy path does) and return a distinct 409 "vote not accepted" error,
  so the two states aren't conflated and a retry on another connection can
  still land.
- connection-registry.ts: extract findPendingPermissionEntry shared by
  findPendingPermission and deletePendingPermission so the matching predicate
  lives in one place; delete now stops at the first (globally unique) match.
- index.ts: the abandonPending callback logs-and-returns-false before the
  dispatcher is initialized instead of throwing through the teardown path,
  matching the detachClient callback's defensive posture.
- Tests: cover the previously-untested handler branches (missing requestId,
  invalid outcome shapes, cancelled outcome, bridge rejection + sessionId
  inference + entry retention) and assert the connection-qualified id format
  and the undefined-sessionId lookup branch.

  dropped a vote silently. Add a writeStderrLine so a vote rejected on the
  legacy path leaves the same grep-friendly operator signal the
  session/permission handler already emits — otherwise the agent's prompt
  stays blocked until teardown with no log to correlate.
- transport.test.ts: add end-to-end coverage for two previously-untested
  handler branches — the no-pending 404 response (requestId misses the
  registry with no sessionId) and the unowned-session rejection (a
  connection voting on a session it does not own).

* refactor(daemon): harden acp permission lookup and align registry api

Address the third ci-bot review round on PR #5912 (all non-blocking
suggestions):

- connection-registry.ts: collapse the redundant private
  findPendingPermissionEntry pass-through into the public
  findPendingPermission, and align deletePendingPermission to the same
  (requestId, sessionId) argument order so the two can never be called with
  swapped string args (a swap would silently match nothing and leak the
  entry until teardown, with no type error).
- dispatch.ts session/permission: look the pending entry up by the
  globally-unique requestId alone and treat the entry's own session as
  authoritative; when the client supplies a sessionId that does not match,
  reject with an explicit 409 instead of routing requireOwned and the bridge
  vote at the wrong session (which left the real entry to leak until
  teardown).
- Tests: add the sessionId-mismatch rejection case and update call sites for
  the new argument order.

Out of scope and deferred: making the dispatcher's registry a required
constructor parameter (and the dependent dropResolvedPermission cleanup) —
that changes the constructor contract beyond this fix.

* fix(daemon): delete resolved permission by precise map key, fix comment

Address wenshao's review on PR #5912: findPendingPermission matches on
bridgeRequestId (a per-request randomUUID), not the connection-qualified
conn.pending map key. Under multi-client attach a permission_request reaches
every co-owning connection, each minting its own entry that shares the same
bridgeRequestId — so more than one entry can match and the prior "globally
unique, at most one match" comment was wrong.

- connection-registry.ts: correct the findPendingPermission doc to attribute
  uniqueness to the map key (not matched here) and note co-owning connections
  can share a bridgeRequestId, so callers needing a specific entry must act on
  the conn/map-key they already hold.
- dispatch.ts dropResolvedPermission: delete the resolved entry by its exact
  conn/map-key instead of re-matching by bridgeRequestId, which under
  multi-attach could delete a sibling connection's entry and orphan the one
  just resolved. Drops the now-unused req parameter.

deletePendingPermission stays for the session/permission handler, where the
lookup and delete consistently target the same first match.

* fix(daemon): align acp permission errors with REST 404/400/403 shapes

Address wenshao's two [Critical] review findings on PR #5912:

- session/permission no longer falls through to the bridge when the registry
  misses. In the scoped route a sessionId is always supplied, so a stale/
  unknown requestId previously routed to the caller's session, got a bridge
  `false`, and was reported as a thrown 409 — diverging from the established
  `404 -> false` contract of DaemonClient.respondToSessionPermission() and the
  REST route. Now a registry miss returns 404; 409 is reserved for a present
  entry the bridge still rejects.
- Wrap the bridge vote and map permission-specific throws like REST's
  sendPermissionVoteError: InvalidPermissionOptionError -> INVALID_PARAMS with
  httpStatus 400 + invalid_option_id, PermissionForbiddenError -> httpStatus
  403 + permission_forbidden (with requestId/sessionId/reason). Previously
  these fell through the outer catch into a generic httpStatus-less internal
  error, so SDK callers saw 500s for normal permission outcomes. Import the
  error classes from acp-session-bridge (as REST does) so instanceof matches
  the class the bridge throws.
- Tests: cover the 404-on-miss-with-sessionId regression and the 400/403
  mappings.

* refactor(daemon): unify permission delete, whitelist vote forward

Address the fourth ci-bot review round on PR #5912 (non-blocking
suggestions):

- session/permission success path now drops the resolved entry through the
  shared dropResolvedPermission helper using the conn/map-key pendingRef
  already carries, instead of re-matching by requestId. Unifies the two
  delete sites and keeps the deletion precise.
- parsePermissionResponse forwards only the bridge-contract fields (outcome
  plus the ACP-reserved _meta passthrough) rather than copying every
  remaining client key, removing a needless client-controlled surface on the
  server-side bridge argument.
- transport.test.ts: the cross-connection permission test now asserts a
  duplicate vote on the same id does not reach the bridge again, locking down
  the cleanup guarantee that is the core of this PR.

Declined (replied on the threads): a blanket local try/catch around the
bridge vote (would shadow the outer dispatcher's typed-error mapping for
non-permission errors) and success-side audit logging in the generic
findPendingClientRequest (log noise / out of scope).

* fix(daemon): full REST parity for acp permission vote errors

Address the fifth ci-bot review round on PR #5912:

- session/permission now maps every permission-specific bridge throw like
  REST's sendPermissionVoteError: InvalidPermissionOptionError -> 400,
  PermissionForbiddenError -> 403, PermissionPolicyNotImplementedError -> 501
  (policy), CancelSentinelCollisionError -> 500 (requestId/sentinel). The last
  two previously fell through to the outer dispatcher catch and became a
  generic -32603 without structured metadata.
- Truly unexpected bridge/sessionCtx failures now run the same
  cancelAbandonedPermission fallback as the legacy resolveClientResponse path
  (dropping the entry only if the cancel landed, else keeping it for teardown)
  before rethrowing — so an unexpected error no longer leaves the mediator
  blocking the agent's prompt until session teardown.
- parsePermissionResponse rebuilds the outcome sub-object from its validated
  keys instead of forwarding it verbatim, so a client can no longer inject
  extra outcome sub-fields (e.g. force) into the bridge argument; _meta is
  forwarded only when it is an object.
- Tests: cross-connection vote via the session/permission method (ack on the
  voter's stream + entry removed from the originator), plus the 501 and 500
  error mappings.

* fix(daemon): preserve answers payload and delete only the voter's own entry

Address wenshao's two [Critical] findings on PR #5912:

- parsePermissionResponse no longer drops the AskUserQuestion `answers`
  payload. The whitelist tightening forwarded only outcome/_meta, but the
  bridge treats `answers` (an object map of string values) as the one
  supported non-ACP permission-response field, so votes were resolving while
  the agent received no submitted answers. Forward it under the same shape the
  bridge validates.
- The session/permission success path now deletes only the voting
  connection's OWN pending entry for the requestId, not the first
  registry-wide match. pendingRef can belong to a sibling connection; under
  the consensus policy respondToSessionPermission returns true for an
  intermediate "recorded" vote, so deleting a sibling's entry could drop a
  co-owner's still-needed request and stall the quorum. A cross-connection
  voter with no own entry deletes nothing and leaves the originator's entry
  for teardown.
- Tests: forward-answers/strip-unknown-fields case, and the cross-connection
  method test now asserts a co-owner's vote does NOT delete the originator's
  sibling entry.

* fix(daemon): validate legacy vote path and scope permission deletes to voter

Address the sixth ci-bot review round on PR #5912 (2 Critical + 4 suggestions):

- resolveClientResponse now validates/whitelists the client result through the
  same parsePermissionResponse the session/permission handler uses. This PR
  had widened that legacy path to any co-owning connection (via
  findPendingClientRequest), so the raw `result as unknown` cast was a
  cross-connection injection surface for arbitrary top-level args and extra
  outcome sub-fields; a malformed result still throws and hits the cancel
  fallback as before.
- The unexpected-error cancel fallback in the session/permission handler now
  drops only the VOTING connection's own entry (via the new shared
  dropOwnPendingPermission helper), not pendingRef — which is the first
  registry-wide match and may be the originator's entry, whose deletion would
  stall a consensus quorum still awaiting other co-owners.
- parsePermissionResponse logs a stderr line when a present-but-malformed
  `answers` is dropped, instead of silently discarding it.
- Removed ConnectionRegistry.deletePendingPermission: it had no production
  callers and its first-match semantics were unsafe under co-owned sessions
  (deletion is done connection-scoped in the dispatcher).
- Tests: _meta object-preserved / non-object-dropped, and the generic
  unexpected-error fallthrough (cancel fallback runs + error propagates).

* fix(daemon): structured 403 for unowned session/permission vote

Address wenshao's remaining [Critical] on PR #5912: the session/permission
ownership rejection went through the shared requireOwned, which sends an
INVALID_PARAMS error with no `data` envelope. Every other error path in this
handler carries `{ httpStatus }` (404/409/400/403/500/501), so SDK callers
that classify permission-vote failures by error.data.httpStatus got undefined
for the likeliest cross-connection failure (right session header, no
session/new on this connection). Inline the ownership check so the rejection
carries httpStatus 403 + sessionId + requestId, leaving the shared requireOwned
untouched for other handlers. Test asserts the 403.

(wenshao's other two criticals — legacy raw-result forwarding and the
catch-all deleting the originator's entry — were already fixed in 4bb06e5fd.)

c302e3ec29 feat(daemon,sdk): resumable /acp session stream (Last-Event-ID) + opt-in SDK transports export (#5852)
* fix(daemon): resume /acp session stream via Last-Event-ID (recover mid-turn content)

The `/acp` Streamable-HTTP session event stream was live-only: it emitted no
SSE `id:` sequence and ignored a `Last-Event-ID` reconnect header. When a
control-plane proxy idle-closed the long-lived SSE mid-turn, every content
frame the daemon produced during the gap (`session/update` carrying
agent_thought_chunk / agent_message_chunk) was lost — the turn still settled,
so the UI showed "done" with an empty/truncated body, and only a re-send
recovered it (tracked as §1.8 in the integration notes).

The replay engine already exists and is battle-tested on the REST surface:
EventBus assigns a monotonic per-session `id`, keeps a bounded ring, and
`subscribeEvents({ lastEventId })` replays `id > lastEventId` before live
events flow. This wires the `/acp` transport to it — no eventBus/bridge change.

- transport-stream / sse-stream / ws-stream: `send(message, id?)`. SSE emits an
  `id:` line when `id` is present (mirrors REST `formatSseFrame`); WS ignores it
  (stateful, no replay).
- connection-registry: `sendSession(…, id?)` threads the cursor; the pre-attach
  session buffer stores `{ frame, id? }` so a buffered frame keeps its `id:`.
- dispatch: `translateEvent` passes `event.id` for bus events; `pumpSessionEvents`
  forwards `lastEventId` to `subscribeEvents`.
- index: the `GET /acp` session branch reads `Last-Event-ID` (strict
  decimal-only parse, same rule as REST) and passes it to the pump.

Bus-originated frames (session/update, request_permission, daemon notifies)
carry an `id:`; JSON-RPC responses and synthetic terminal frames do not, so
they don't burn a slot in the resume sequence. Backward compatible: clients
that send no `Last-Event-ID` get live-only behaviour as before, and `id:`
lines are inert for clients that ignore them.

Design: docs/design/daemon-acp-http/sse-resumable-stream.md

* fix(daemon): make /acp resume actually engage — session-stream grace/reclaim + replay guards

Addresses three review Criticals on the §1.8 plumbing: on its own the
`id:`/`Last-Event-ID` wiring never fired in the real close-then-reconnect flow,
and once it does fire two replay-correctness gaps become reachable.

1. Session-stream grace/reclaim (the core fix). A transport-level session-stream
   close used to run the FULL `closeSessionStream` teardown — removing
   ownership, aborting the in-flight prompt, detaching the bridge client. In the
   real EventSource/proxy order (old socket closes first, then reconnect) that
   meant the reconnect carrying `Last-Event-ID` was rejected 403 before the
   cursor was read, and the prompt was already aborted — so replay had nothing
   to resume. Now a transport close DETACHES (`detachSessionStream`): it stops
   only the stream + subscription and keeps the binding, ownership, prompt, and
   bridge-client alive for a grace window (`SESSION_GRACE_MS`, mirrors
   `CONN_GRACE_MS`). A reconnect within the window reclaims (clears the timer);
   otherwise the grace timer runs the full teardown, bounding runaway cost. Full
   teardown stays immediate for explicit `session/close` and connection destroy.
   The GET handler branches on `stream.isClosed` (transport close → grace;
   pump-ended-while-open → full close).

2. No double-delivery (buffer ↔ ring overlap). `attachSessionStream` records the
   max bus id flushed from the pre-attach buffer; the GET handler advances the
   replay cursor to `max(Last-Event-ID, lastFlushedEventId)` so the ring replay
   doesn't re-emit an already-flushed frame.

3. Idempotent `permission_request` under replay. `translateEvent` reuses the
   existing `conn.pending` entry for a `bridgeRequestId` (re-sends the same
   outbound id) instead of minting a second id+entry — no orphan pending, no
   duplicate prompt on a ring-replayed permission.

Also: extract `parseLastEventId` to a shared `serve/sse-last-event-id.ts` used
by both REST and `/acp` (no drift; logs the rejected value); log `lastEventId`
in the pump error.

Tests: real close-then-reconnect order (200 not 403 + prompt not aborted);
overflow Last-Event-ID; replayed permission reuses pending id; registry
grace/reclaim + buffer-flush-preserves-id. Full acp-http suite green (216).

* feat(sdk): expose ACP transports via opt-in ./daemon/transports subpath

The resumable ACP-over-HTTP transport (AcpHttpTransport, native
supportsReplay + Last-Event-ID) and the negotiateTransport factory were
reachable only from source paths inside the monorepo — the published
`@qwen-code/sdk/daemon` barrel intentionally omits them to keep its
budget-checked browser bundle lean, so external consumers (agent-web)
had no import path short of forking.

Add a separate opt-in subpath `@qwen-code/sdk/daemon/transports` that
ships AcpHttpTransport / AcpWsTransport / AutoReconnectTransport /
RestSseTransport / negotiateTransport as their own browser+node bundle.
The default `./daemon` barrel and its byte budget are unchanged, so
REST-only consumers stay tree-shaken and pay nothing for the transports.

Also add a `fetchFn` option to NegotiateTransportOptions so callers can
inject auth/proxy/test fetch instead of the hardcoded global.

- build.js: emit dist/daemon/transports.{js,cjs}; reuse the node-builtin
  guard for the new browser bundle (no size budget — it legitimately
  ships the transports) while keeping the default barrel's budget check.
- daemon/index.ts: update the rationale comment to point at the subpath.
- daemon-transports-surface.test.ts: lock the runtime + type surface and
  the package.json exports entry.

* fix(daemon): resume cursor must not skip in-flight-lost frames

Round-3 review (qwen-code-ci-bot) flagged a silent-frame-loss Critical in
the §1.8 resume path I added: `resumeCursor = max(Last-Event-ID,
lastFlushedEventId)` advances the ring-replay cursor past the buffer, but a
frame sent to the now-dead socket yet never received by the client has a bus
id BELOW the buffer's ids and ABOVE the client's cursor — so the max() skips
it and the ring replay never re-emits it. Exactly the proxy idle-close
mid-turn frame §1.8 is meant to recover.

Fix without trading loss for duplicates: a buffered bus event is ALSO in the
EventBus ring (it was published there to get its id), so the ring replay
started at the client's cursor is the single delivery path for every bus
event after the cursor. `attachSessionStream` now takes the resume cursor and,
when resuming, does NOT flush id-bearing buffered frames — the ring owns them,
delivering each exactly once including the in-flight-lost frame. Id-less
frames (JSON-RPC replies via `replySession`, not ring events) are still
flushed — their only delivery path. The GET handler sets
`resumeCursor = lastEventId` verbatim; `lastFlushedEventId` is removed.

Also from the same review:
- sse-last-event-id `safeLogValue`: strip ALL C0 control chars + DEL (not just
  CR/LF) so a crafted `Last-Event-ID` can't smuggle ANSI ESC / null bytes onto
  an operator's terminal via stderr.
- ws-stream: regression test asserting `send(msg, id)` keeps the WS wire frame
  bare JSON (no SSE `id:` framing leak).
- connection-registry: resume-path test (id-bearing frames skipped, id-less
  reply still flushed); design doc updated.

* refactor(daemon): inline resumeCursor alias to lastEventId

Review nit (yiliang114): after the prior commit dropped the `max()` logic,
`resumeCursor` is a pure alias for `lastEventId`. Use `lastEventId` directly in
the `pumpSessionEvents` call and the error log; drop the alias.

* docs(daemon): refresh stale resume comments + add gap-delivery test

Round-4 review (qwen-code-ci-bot, against the now-corrected resume model):

- connection-registry: the attachSessionStream CONTRACT comment still cited a
  `promptAbort?.abort()` call in the index.ts onClose handler that an earlier
  commit removed. Rewrite it to describe the current model — each stream's pump
  has its own abort controller and teardown is identity-guarded in
  `onPumpSettled`, so installing the new stream first makes the old stream
  settle into detach-with-grace rather than tearing down the in-flight prompt.
- dispatch: the stream_error frame comment ("no bus id, so no SSE id: line")
  contradicted the code passing `event.id`. Make it truthful: pass the cursor
  through if present; a synthetic terminal frame has no id so none is written.
- connection-registry.test: add the explicit detach → produce gap events →
  reattach → flush-exactly-once test (the PR's core value prop at the registry
  layer), incl. a second reattach asserting the buffer drained.

The two Criticals in the same review referenced `resumeCursor` /
`lastFlushedEventId` / `Math.max`, all removed in prior commits — obsolete
against current code (answered + resolved on the threads).

* fix(daemon): preserve stream order on resume + harden grace/permission paths

Round-5 review (wenshao + qwen-code-ci-bot):

- [Critical, wenshao] Out-of-order completion on resume. attachSessionStream
  flushed id-less buffered JSON-RPC replies (e.g. a session/prompt result that
  landed during the detach gap) immediately — ahead of the ring replay that
  redelivers the content chunks preceding them, so a client could see "prompt
  complete" before the body (the truncated-body failure §1.8 fixes). Now on
  resume those id-less frames are DEFERRED in the buffer; the event pump
  releases them via flushBufferedSessionFrames once the replay boundary
  (replay_complete / state_resync_required) passes, preserving original order.
  Fresh connects (no cursor, no replay) still flush the whole buffer in order.

- [Critical, ci-bot] Permission auto-denied during the reconnect grace window:
  a permission_request arriving while binding.stream is detached cancel-denies,
  so a client reconnecting within grace can't vote. The structural fix (defer
  the vote across grace) belongs with the §1.7 permission-coordination
  follow-up; here, log an operator breadcrumb when it fires during grace, and
  document the synchronous-translateEvent INVARIANT the direct binding.stream
  .send relies on.

- [ci-bot] Stale-stream detach is now tested (reclaim installs s2; a late s1
  close is a no-op — no teardown, no grace re-arm). Grace-expiry teardown now
  logs a breadcrumb so a vanished session is distinguishable from explicit
  close. TS4111: bracket-access the index-signature exports entry in the SDK
  surface test. transports browser bundle now has a size budget
  (MAX_TRANSPORTS_BROWSER_BUNDLE_BYTES = 48KB; current ~29KB).

* fix(sdk): route session-scoped /acp responses so prompts don't hang

[Critical, wenshao] The published AcpHttpTransport could hang real
session/prompt + config requests. Its subscribeEvents() opened REST
GET /session/:id/events and only sendRequest's connection-scoped stream
resolved responses — but the daemon's replySession() routes session-scoped
JSON-RPC replies onto the session-scoped /acp stream, which the transport
never read. So a session/prompt reply was never observed → the pending
request never settled.

Switch subscribeEvents to the session-scoped /acp stream (GET /acp +
Acp-Session-Id) — the resumable §1.8 stream the daemon puts session replies
on — and dispatch each raw JSON-RPC frame by shape:
- response (id, no method)      → resolve the shared pending map (the fix)
- notification (method, no id)   → DaemonEvent via denormalizeAcpNotification,
                                   stamped with the real bus id from the SSE
                                   `id:` line (the synthetic denormalizer id is
                                   not resume-compatible; supportsReplay=true
                                   now tracks the authoritative cursor)
- session/request_permission     → surfaced as a permission_request event so
                                   consumers still see prompts (responding to
                                   the vote is the §1.7 follow-up)

The connection-scoped stream still carries replies to connection-level
requests (initialize, session/new). Adds 4 subscribeEvents unit tests
(stream selection + headers, notification→event+busId, response consumed-not-
yielded, permission surfaced). Full SDK suite green (1062).

* fix(sdk,daemon): harden /acp SSE parser + grace/flush observability

Round-6 review (qwen-code-ci-bot), all additive / no behavioural side effects:

- [Critical] Unbounded SSE buffer in the new AcpHttpTransport session-stream
  parser → OOM (tab crash for browser consumers). Add a 16 MiB cap mirroring
  parseSseStream's MAX_BUF_CHARS, and reuse parseSseStream's CRLF-aware
  `consumeFrames` splitter (now exported) instead of an inline `\n\n` scan —
  closing the CRLF, multi-line `data:` join, and trailing-CR gaps in one go.
- Deferred-flush ordering race: the pump's post-loop safety flushDeferred()
  now runs only on a non-aborted exit. An abort means the stream was
  detached/reclaimed; flushing there could drain the deferred reply onto a
  reclaiming stream ahead of its own replay (reintroducing the out-of-order
  delivery the deferral prevents). On error the frames stay buffered for the
  next attach — never lost.
- Grace reclaim now logs (detach + grace-expiry already did) so the reconnect
  trail is complete for operators.
- sse-last-event-id doc: corrected the "shared by REST and ACP" claim — after
  the #5809 serve-route split REST keeps its own copy; unifying them would
  touch REST, so it's deferred (this PR keeps REST untouched).

Thread on a full deferred-flush integration test: the ordering invariant is
already locked at the unit layer (flushBufferedSessionFrames defer test +
gap-delivery test); a full-HTTP timing test against the FakeBridge would be
flake-prone, so it's intentionally not added.

* fix(daemon,sdk): harden /acp resumable stream from review round 7

Address review-pr findings on the §1.8 resumable stream, all additive /
backward-compatible (REST untouched, no behavioural side effects):

- connection-registry: guard flushBufferedSessionFrames against a closed
  stream so deferred replies stay buffered for the next reconnect instead
  of being dropped onto a dead socket. Keep the synchronous in-order
  enqueue (SseStream serializes via one writeChain) — an await-per-frame
  drain would let a live event interleave between deferred frames and
  reorder the very replies this deferral preserves (W1).
- connection-registry: log at the moment of detach so an operator can
  measure the real disconnect→reconnect gap against the grace window.
- index: route sessionId through logSafe() in the event-pump error log,
  matching every other log line this PR adds (terminal-escape hardening).
- AcpHttpTransport: remove the abort listener in the finally block so a
  long-lived signal reused across reconnects doesn't accumulate listeners.
- AcpHttpTransport: parse the SSE `id:` cursor with the server's strict
  /^\d+$/ + MAX_SAFE_INTEGER rule instead of lenient Number() (rejects
  proxy-mangled hex/exponential/empty cursors).
- AcpHttpTransport: document that an unparseable non-empty data frame is a
  corrupt frame (not a heartbeat); tracing it is a follow-up once the SDK
  grows a logger (the package lint config forbids console).
- tests: add sse-last-event-id.test.ts (parseLastEventId accept/reject +
  safeLogValue control-char stripping/truncation) and a
  flushBufferedSessionFrames closed-stream-retains-buffer case.

* fix(daemon,sdk): round-8 review hardening for /acp resumable stream

All additive / backward-compatible (REST untouched, no behavioural side
effects):

- AcpHttpTransport: attach a no-op catch to abortPromise so an
  already-aborted signal at entry (loop never enters, Promise.race never
  consumes the rejection) can't surface as an unhandled rejection.
- AcpHttpTransport: document that opts.maxQueued does not apply to the
  /acp transport (the session stream is backed by the daemon's
  server-controlled EventBus ring; there is no client-tunable queue to
  forward it to) — intentionally ignored, not silently mis-applied.
- index: run err.message through logSafe() in the event-pump error log
  (CR/LF/ANSI in a bridge error string would otherwise reach stderr raw),
  and add operator breadcrumbs for the previously-silent onPumpSettled
  branches (pump-ended-while-open full close; superseded-stream no-op),
  completing the detach/reclaim/grace trail.
- tests: assert subscribeEvents writes Last-Event-ID on the outbound GET
  when resuming and omits it on a first connect (the resume cursor must
  reach the wire), plus an already-aborted-signal case that would fail on
  an unhandled rejection without the catch above.

* fix(daemon): flush deferred /acp replies on replay_complete only

The EventBus emits `state_resync_required` BEFORE the replay frames (the
`epoch_reset` and `ring_evicted` paths both fall through to the replay
loop and still emit `replay_complete` at the end). The pump was releasing
the deferred id-less replies on EITHER boundary, so on a resync-triggering
resume the buffered `session/prompt` result was flushed ahead of the
replayed content chunks — the exact truncated-body reordering §1.8 fixes
(client sees "done" before the body).

Flush on `replay_complete` only. The live-only case (no cursor ⇒ no replay
⇒ no `replay_complete`) is still covered by the pump's post-loop safety
flush. Add an over-the-wire integration test (resume with a reply buffered
during the detach gap, bridge replays resync → content → replay_complete)
asserting the reply lands AFTER the replayed content; verified it fails
against the previous dual-boundary flush. Design doc updated.

Co-authored-by: Qwen-Coder <[email protected]>

* fix(daemon): close two §1.8 grace/replay-ordering holes

Both additive / in-scope / no REST change:

- Replay-window reply ordering (connection-registry, dispatch): the
  resumptive-attach deferral only covered id-less replies ALREADY buffered
  from the detach gap. A prompt that finished AFTER the new stream attached
  but BEFORE replay drained went straight out live via `sendSession`,
  overtaking replay frames not yet sent. Add a per-binding `replayPending`
  flag (armed on resumptive attach, cleared on `replay_complete` in
  `flushBufferedSessionFrames`) and route `replySession`'s out-of-band
  replies through a new `sendSessionReply` that defers while it's set.
  In-band pump frames keep using `sendSession`, so the `replay_complete`
  frame itself can't be deferred (which would deadlock the release).

- Connection reaper vs session grace (index, connection-registry): the
  conn-stream-close reaper treated only LIVE session streams as activity,
  so a session detached into its own `SESSION_GRACE_MS` window (stream
  undefined, graceTimer armed) didn't count — the connection could be
  reaped at `CONN_GRACE_MS`, 404-ing the imminent session resume and
  aborting the in-flight prompt early. Add `hasRecoverableSession()` and
  treat a grace-armed session as activity in the reaper guard.

Unit tests for both at the registry layer.

* fix(sdk): thread query params into ACP transport route extractors

The exported ACP HTTP/WS transports reduced request URLs to `pathname`
before the route table built JSON-RPC params, so every query parameter
from the REST-style DaemonClient helpers was dropped — e.g.
`readWorkspaceFile('a.ts', { maxBytes: 123 })` (`/file?path=a.ts&maxBytes=123`)
produced `_qwen/file/read` with `params: {}`. Same for `/file/bytes`,
`/stat`, `/list`, `/glob`, and `context-usage?detail=true`.

Pass `parsedUrl.searchParams` into `extractParams` and coerce each query
value to the type the daemon's ACP handlers require — the daemon validates
`maxBytes`/`line`/`limit`/`offset` as real numbers and `detail` as the
boolean `true`, neither of which a raw query string satisfies. Helpers
`strParam`/`numParam`/`boolParam` keep the per-route extractors terse.
`query` is optional so the existing path-only extractors are unaffected.
(`/workspace/voice/transcribe` has no ACP route at all — separate gap,
binary audio doesn't belong on the JSON-RPC transport.)

* fix(sdk): route session-stream replies via a background pump (no-subscriber prompt)

The daemon answers POST /session/:id/prompt (and session/cancel,
set_config_option, set_mode, set_model) with 202 and routes the JSON-RPC
result onto the SESSION stream via replySession — not the connection
stream the transport pumps. So a DaemonClient that calls prompt() but
never iterates subscribeEvents had nothing reading that reply, and
sendRequest()'s pending promise never resolved → prompt() hung forever.

For these session-reply methods, sendRequest now opens a reference-counted
background session-reply pump (GET /acp + Acp-Session-Id) that routes
JSON-RPC responses to `pending`, released when the request settles. It's
suppressed when a subscribeEvents consumer is already iterating that
session (tracked via activeSessionSubscriptions) — the daemon's session
stream is single-reader, so a competing GET would detach the consumer's;
in that case the consumer already routes the reply (the W2 fix). The pump
skips notifications and permission requests (method-bearing frames) so a
permission request id can't be mis-routed onto a pending response slot.
All five methods require an owned session, so the pump's GET is always
authorized. Disposed pumps are aborted in dispose().

Verified the new test times out without the pump and passes with it.

* fix(serve): sequence /acp deferred replies by bus watermark + harden grace/reap

Address review on the §1.8 resumable-stream fixes:

- replayPending is now set from the current attach mode every time
  (resume arms, fresh connect clears) so an aborted resume that skipped
  its boundary flush can't strand the flag and buffer every later reply
  forever (MsyIq, MylZ4).
- Deferred out-of-band replies carry a watermark (anchorId = bus head at
  produce time) and release only once the pump delivers through that id,
  via per-event releaseDeferredSessionReplies + endReplayDeferral at
  replay_complete. A result produced during a slow replay no longer jumps
  ahead of tail content still flowing as live events behind the boundary
  (MsyIt). Unanchored fallback replies still release at the boundary.
- Connection reap re-evaluates after a session reclaim grace expires
  (connGraceExpired + onSessionGraceExpired), so a conn blocked from
  reaping by a then-recoverable session no longer lingers to the 30-min
  idle sweep (MsyIs).
- Wrap the grace-timer teardown in try/catch so a throwing detach
  callback can't crash the daemon from a bare setTimeout (MylZ8).
- sse-last-event-id reuses the shared logSafe sanitizer (covers C1 +
  Unicode bidi) instead of a narrower divergent regex (M1isz); refresh
  stale replayPending/flush JSDoc (MselO).

Unit tests cover the replayPending reset, watermark ordering, grace
expiry hook, and grace-timer try/catch.

* fix(sdk): scope pending sweeps per stream + reset bus cursor on invalid id

Address review on the ACP HTTP transport:

- Tag each pending request with its routing scope (connection vs a
  sessionId). A connection-stream failure now sweeps only conn-scoped
  pendings, so it can't reject a session/prompt the session stream is
  about to resolve; the session reply pump mirrors this for its own
  scope (MselM).
- An invalid id: line later in an SSE frame resets the bus cursor to
  undefined rather than carrying a stale earlier value into the event
  (MselW).
- Strengthen the W2 response-routing test to register a pending request
  and assert the frame RESOLVES it, not merely that it isn't yielded
  (MylZ-). Add tests for the per-stream sweep partition and the id reset.

* fix(sdk): accept `kind`-tagged _qwen/notify envelopes (don't drop resume signals)

The daemon's session-stream translateEvent stamps `_qwen/notify` events
under `kind` (state_resync_required, replay_complete, stream_error,
model_switched, …), but denormalizeAcpNotification read only `type` and
returned undefined for them — so subscribeEvents silently dropped every
such event. During a ring-overflow resume the SDK would never see
state_resync_required and would apply replayed events to stale state.

Read `params['type'] ?? params['kind']` (preferring `type`, so other
producers are unaffected) and add an SDK test feeding a `kind`-tagged
notify through subscribeEvents (M2bvl).

* fix(sdk): reject session-scoped pendings when the subscription stream closes

A `session/prompt` reply routed through an active subscribeEvents consumer
(no reply pump is started while a subscription is live) would hang if that
session SSE stream closed before the reply arrived: the connection-stream
catch only sweeps conn-scoped pendings, and subscribeEventsInner's finally
cleaned up the reader but never the pendings.

Sweep session-scoped pendings in that finally too, gated so it only fires
when this is the session's last delivery route (no other active
subscription — the ref-count still includes self here — and no reply pump),
mirroring the reply-pump and connection-stream sweeps. Add a regression
test (M2iHz).

* fix(sdk): harden ACP SSE readers + reply-pump handoff + empty query param

Address the latest review wave on the transport:

- pumpConnStream now bounds its unread SSE buffer with the same
  MAX_SSE_BUF_CHARS guard the two session readers already have — the OOM
  vector (a server that never emits a `\n\n` boundary) was open on 1 of 3
  readers — and attaches the no-op abortPromise.catch() crash guard (M3BYQ).
- pumpSessionReplies mirrors subscribeEventsInner's abort handling: named
  listener ref removed in finally (no leak on a clean drain of a reused
  signal) + abortPromise.catch() so a pre-aborted signal can't surface an
  unhandledrejection; and it throws the HTTP status on a non-OK response so
  the failure is diagnosable rather than a silent void return (M3BYT, M3BYY).
- subscribeEvents aborts any existing background reply pump for the session
  before opening the consumer stream. The single-reader session stream
  detaches the pump anyway; aborting it skips its teardown sweep so it can't
  spuriously reject the very `session/prompt` the consumer now delivers (M3BYa).
- numParam treats an empty value (`?maxBytes=`) as absent, not Number('')===0
  (M3BYd).

Tests: empty-numeric-param omission, and the reply-pump abort-on-subscribe
handoff (pump aborted, its pending not rejected).

* fix(sdk): validate content-type in pumpSessionReplies before parsing as SSE

pumpSessionReplies fed any 2xx body straight to the SSE frame parser. A
non-SSE response (an HTML error page / a JSON proxy error injected by a
CDN) would be consumed as garbage or hang the pump waiting for `data:`
lines that never arrive — strictly weaker validation than its sibling
subscribeEventsInner, which already guards content-type.

Mirror that guard: between the res.ok check and getReader(), reject a body
that isn't text/event-stream (cancelling it first). Add a test that a
no-subscriber session/prompt whose reply pump GET returns text/html
rejects instead of hanging (M3pAM).

* fix(sdk): close reply-pump handoff strand race + scope-guard reply resolution

Address the latest review wave:

- subscribeEvents now removes the aborted reply pump's map entry
  SYNCHRONOUSLY, not just aborting it. Otherwise, if the subscription
  exited before the pump's async `.finally` deleted the entry, BOTH
  stranded-pending guards missed (the consumer sweep saw the entry still
  present and deferred; the pump's sweep skipped on abort) — a live
  session/prompt stayed in `pending` forever. Synchronous removal makes the
  consumer sweep deterministically responsible (M3w6Y).
- Reply resolution (both the session-reply pump and the subscribeEvents
  consumer path) now skips a reply whose pending is scoped to a DIFFERENT

  cross-delivering across the SDK boundary (M3w6d).
- denormalizeAcpNotification prefers a NON-EMPTY `type`; an empty-string

Tests: reply-pump handoff happy-path (delivers/resolves) + strand case
(rejects, not stranded); empty-`type`→`kind` fallback; the SSE buffer cap
firing; the unanchored-reply hold/release branches; and connGraceExpired
reset on reconnect (M3w6e, M3w6f, M3w6g).

* fix(sdk): sweep session pendings in the subscribe wrapper + carry pump error

Two follow-ups on the reply-pump handoff:

- The session-scoped pending sweep moves from subscribeEventsInner's
  read-loop finally to the subscribeEvents WRAPPER finally. The read-loop
  finally only runs once the pump reaches the loop; a fast failure (fetch
  reject / non-OK / wrong content-type, all before the loop) skipped it and
  stranded the pending. The wrapper finally always runs, so it covers the
  fast-fail path too (M4DWq).
- ensureSessionReplyPump captures the pump's error (HTTP 401/404, wrong
  content-type) and rejects swept pendings WITH it instead of a generic
  message, so a caller can tell auth failure from a network drop (M4DWx).

Test: a 401 on the session GET (inner throws before its read loop) still
rejects the in-flight session-scoped pending via the wrapper sweep.

* fix(sdk): carry the subscription error into the wrapper sweep + guard tests

Follow-ups on the reply-pump handoff:

- The subscribeEvents wrapper sweep now rejects with the actual cause of the
  subscription's exit (captured from a try/catch around the inner generator)
  instead of a hard-coded generic message. On the fast-fail path (401 /
  wrong content-type thrown before the inner read loop) this wrapper finally
  is the only sweep that fires, so the caller now sees the real failure —
  parity with the reply-pump's pumpError reason (M4W9a).

Tests:
- the fast-fail sweep reason carries the 401 (not a generic message);
- the M3pAM non-SSE rejection asserts the content-type cause reaches the
  caller (proves pumpError propagation) (M4W9g);
- cross-session scope guard, both the consumer and the reply-pump
  resolution paths: a reply on session A's stream must not resolve a pending
  scoped to session B (M4W9e).

* fix(serve): guard onSessionGraceExpired in the grace timer against an uncaught throw

The session grace-expiry setTimeout protected closeSessionStream with a

outside it. From a bare setTimeout, an uncaught throw there would crash the
whole daemon — the same hazard the teardown guard exists for. Wrap it in
its own try/catch (separate from teardown, so the conn-reap re-check still
runs even if teardown threw). Add a regression test (M4i9z).

* fix(sdk): make conn-stream pump CRLF-aware; align replay opt-in doc

The connection-scoped SSE reply pump split frames with an LF-only
`buf.indexOf('\n\n')`. A server or proxy emitting `\r\n\r\n` frame
separators produces no `\n\n` substring, so the scan never found a
boundary: the unread buffer grew to the OOM cap and the pump threw,
leaving every connection-scoped JSON-RPC reply unresolved. Reuse the
shared CRLF-aware `consumeFrames` splitter (and strip a trailing CR
per data line) so the conn pump frames exactly like the session
readers. Add a regression test that delivers a conn-scoped reply over
`\r\n\r\n` and asserts it resolves.

Also update the design doc: the in-repo SDK `AcpHttpTransport` opts in
to replay in this PR (`supportsReplay = true` + resends Last-Event-ID),
so the backward-compat note no longer reads as "keeps false until it
opts in". Only the external agent-web transport flip stays deferred
(already listed under Out of scope).

* fix(daemon,sdk): log replay-deferral arm; document session-reply routing invariant

Add a stderr breadcrumb when a resume arms `replayPending`: while armed,
`sendSessionReply` defers every out-of-band reply until the pump delivers
`replay_complete`. If that sentinel never arrives (a dropped frame or a
pump error), the replies stay buffered indefinitely with no other trace —
the log gives operators a starting point. Silent on a fresh connect (no
deferral). Covered by a new test.

Also strengthen the `SESSION_STREAM_REPLY_METHODS` doc comment: name the
authoritative daemon call sites (dispatch.ts), spell out the hang failure
mode if the set drifts, and record a build-time grep / shared-constant
enforcement as a follow-up (a cross-package invariant the SDK can't type-check).

* fix(sdk): don't silently hang conn-scoped requests on a failed conn stream

`pumpConnStream` swallowed two failure paths: a non-2xx / no-body `GET
/acp` did a bare `return`, and read-loop errors were caught and dropped.
Either way the pump promise RESOLVED, so `openConnStream`'s `.catch`
never ran — connection-scoped JSON-RPC pendings stayed in the map
forever, and `connStreamAbort` was never cleared, so `ensureConnStream`
saw it non-null and never reopened the stream (every later 202 request
hung with no pump to deliver its reply).

- A non-2xx / missing-body response now throws (HTTP status in the
  message) so the catch sweep rejects the conn-scoped pendings.
- The read-loop catch rethrows real errors and only swallows an
  intentional abort (dispose / reconnect, which owns its own cleanup).
- `openConnStream` clears `connStreamAbort` in a `.finally` (guarded on
  controller identity) so the stream reopens on the next request after
  ANY settle — clean close, error, or abort.

Regression test: a 500 `GET /acp` rejects the conn-scoped pending (leaves
session-scoped ones for their own stream) and the next request reopens.

* fix(daemon,sdk): conn-stream error propagation, listener cleanup, buffer eviction, param parsing

Address review findings on the resumable /acp stream and exported SDK
transports — all additive/backward-compatible, REST untouched:

- openConnStream: reject connection-scoped pendings with the pump's REAL
  error (HTTP 401/503, network drop) instead of a generic message, mirroring
  ensureSessionReplyPump.
- pumpConnStream: keep the abort listener in a named ref and remove it in
  finally so a long-lived signal reused across reconnects doesn't accumulate
  listeners (mirrors the session readers).
- sendRequest: remove the abort listener on the happy path (the `{ once: true }`
  listener self-removes only when the signal fires), preventing per-call
  listener buildup on a shared caller signal.
- pushCapped: under a content flood, evict a REPLAYABLE id-bearing frame (the
  ring redelivers it) before an irreplaceable id-less deferred reply — dropping
  the latter would hang the session/prompt caller — and log the dropped id.
- acpRouteTable.boolParam: treat a present-but-empty value (`?detail=`) as
  absent, matching numParam, so `{ detail: false }` isn't forwarded for an
  unset param.
- connection-registry resume flush: hoist the `splice(0)` snapshot into a named
  local to make the re-entrant copy-semantics invariant visible.

Tests: boolParam empty-value omission; pre-attach buffer keeps the id-less
reply under a 400-frame content flood. Document two exported-transport
limitations (permission voting; session RPC awaited inside the subscribeEvents
loop) as §1.7-adjacent follow-ups in the design doc.

* fix(daemon): never evict an irreplaceable id-less reply from the pre-attach buffer

The previous pushCapped change preferred evicting id-bearing (ring-replayable)
frames, but left a degenerate hole: when the buffer fills with ONLY id-less
deferred replies (no id-bearing entry exists), findIndex returned -1, dropIndex
fell back to 0, and the oldest deferred JSON-RPC reply was evicted — silently
hanging its session/prompt caller, the exact failure the guard exists to
prevent (wenshao).

Fix: when there is no replayable id-bearing frame to evict, do NOT drop —
append and let the id-less replies exceed the soft cap. The cap is a memory
bound against a CONTENT flood (id-bearing frames); id-less replies are bounded
by the number of in-flight session RPCs the client actually issued
(client-controlled, tiny), so they can't run away in practice. Log once when
over the soft cap. The connection buffer (no id accessor) keeps its FIFO
eviction unchanged.

Test: 300 all-id-less replies buffered past the 256 cap are all delivered on
reconnect, none evicted.

* fix(daemon): hard ceiling + transition-only logging for the id-less reply buffer

Follow-ups on the prior id-less-eviction fix (wenshao):

- Defense-in-depth HARD cap. The soft-cap path never drops id-less replies,
  relying on "id-less replies are RPC-bounded" — true today but enforced only
  by convention. Add HARD_BUFFERED_FRAMES_CAP (4× soft = 1024): past it, drop
  the oldest id-less reply and log loudly, so a future non-RPC-bounded producer
  or a buggy client can't grow the daemon heap without limit.
- Log at the soft-cap transition only (buf.length === MAX_BUFFERED_FRAMES), not
  on every over-cap push — the comment said "once" but it logged linearly with
  over-cap depth (~44 lines for 300 entries).

Tests: assert the soft-cap warning fires exactly once for a 300-entry overflow;
new test that 1100 id-less replies are bounded at the 1024 hard cap (oldest
dropped, newest kept, loud breach log emitted).

* fix(daemon,sdk): release all deferred replies when replay evicted frames; guard conn pump against session-scoped pending

When ring replay overflows and emits state_resync_required, the watermark
anchor guarantee is void (the anchored frame may have been evicted), so
hold-until-watermark could freeze deferred session replies indefinitely.
Track eviction through the pump loop and flush ALL buffered session frames
at replay_complete in that case instead of waiting on the watermark.

Also harden the SDK conn-stream pump: never resolve a session-scoped pending
entry from the connection stream (scope guard), and document the fresh-attach
(non-resumptive) caveat for ensureSessionReplyPump.

* fix(daemon): flush deferred replies on mid-replay iterator error; cover anchored watermark e2e

On an iterator error mid-replay the catch path re-throws, which drives
onPumpSettled; while the session stream is still open that takes the
closeSessionStream branch (full teardown, not a detach-with-grace), so any
still-deferred session replies in the binding buffer were dropped rather than
preserved. Flush them in the catch before signalling stream_error — same
safety flush as the happy-path completion (the iterator has terminated, so no
content frame can still race ahead of them). Correct the now-inaccurate
happy-path comment that claimed error-path frames stay buffered.

Add an end-to-end transport test for the anchored watermark path: with a real
getSessionLastEventId, a deferred reply is held through pre-watermark content
and released ON its anchor mid-replay, before replay_complete — distinguishing
the watermark release from the unanchored release-at-boundary path.

Document two deferrals in the design doc: response-replay idempotency for an
already-resolved permission (a conformant client dedupes on _meta.requestId;
full re-send belongs with the permission-coordination follow-up) and an
automated guard for the SESSION_STREAM_REPLY_METHODS drift.

aborted on detach, so only id-less out-of-band replies accumulate during the
gap; ring replay owns id-bearing recovery and eviction is signalled via
state_resync_required). Document two opt-in-transport edges as
permission-coordination follow-ups: the no-subscriber reply pump's GET stream
causing an agent permission_request to be routed to the pump and dropped, and
why an automated SESSION_STREAM_REPLY_METHODS drift guard needs dataflow (the
prompt reply is decoupled from its case block).

8b4871bbc2 fix(cli): make the non-VP transcript scrollable during multi-agent runs (#6015)
* fix(cli): stop scroll snap-back during parallel-agent runs (non-VP)

In non-VP mode ink clears the whole terminal (including scrollback) on every
repaint once the non-<Static> live frame exceeds the terminal height (see
ink's shouldClearTerminalForFrame). During a parallel-agent run the
pure-parallel inline panel rendered the UNFILTERED toolCalls, so running
subagents were shown inline AND in LiveAgentPanel below the composer — two
full rosters that push the live frame past the viewport. The per-second
elapsed/token ticks then fire that clear continuously, so scroll-up snaps
straight back to the bottom and flickers.

Route the pure-parallel branch through the same inlineToolCalls hand-off as
every other group: during the live phase render only the agents the panel is
not showing (terminal rows en route to <Static>), keeping the header total
honest via totalAgentCount. Add an availableTerminalHeight backstop to
InlineParallelAgentsDisplay that windows the rows ("+N more") so the panel can
never exceed its height budget.

* fix(cli): gate SGR mouse tracking to VP mode so non-VP keeps native scrollback

Enabling SGR mouse tracking (?1002h) makes the host terminal stop doing native
scrollback on the wheel — it hands wheel events to the app (Terminal.app even
diverts them to arrow keys, which then drive composer input history and the
background-agent panel). That is only acceptable when the app itself owns the
wheel: VP mode (ScrollableList) or an alternate-screen modal (ThinkingViewer),
neither of which relies on main-screen scrollback. But a collapsed thinking
block armed mouse tracking just for click-to-expand, unconditionally, so any
non-VP session with thinking blocks could no longer scroll its transcript.

Make useMouseEvents gate on VP mode by default: mouse tracking turns on only
when `ui.useTerminalBuffer` is set. Surfaces that legitimately own the wheel
pass the new `bypassVpGate` option (ScrollableList, ThinkingViewer). The
thinking-block click handler does not, so in non-VP it stays dormant and native
terminal scrollback is preserved (the block still expands via Alt+T). This is a
single chokepoint, so future non-VP mouse subscribers can't reintroduce the
regression.

* fix(cli): tighten inline parallel-agent windowing and drop redundant filters

- InlineParallelAgentsDisplay: the height backstop kept Math.max(1, budget-2)

  data row (3 lines) and overflowed the very budget meant to cap it, which can
  re-trigger the shouldClearTerminalForFrame snap-back. Reserve the header and
  (when overflowing) the indicator first, then window the remaining rows; at a
  budget of 1 keep only the header (its label still states the total). Total
  rendered height now never exceeds the budget. Adds budget=1/2 regression tests.

- ToolGroupMessage: isPureParallelAgentGroup already guarantees every entry is
  a subagent, so the isSubagentToolEntry filters on inlineToolCalls and on
  totalAgentCount were no-ops; use inlineToolCalls and toolCalls.length directly.

- ToolGroupMessage: only forward availableTerminalHeight to

  backstop guards the non-<Static> live frame; once committed the rows live in
  <Static> with no snap-back risk, and MainContent passes staticAreaMaxItemHeight
  (>=100) for committed items. Forwarding that let the cap fire on scrollback and
  could permanently hide completed agents behind a static "+N more". Pass
  undefined when committed, per the component's documented contract.

- InlineParallelAgentsDisplay.test: add a "generous budget" case (10 agents,
  budget 20) pinning the `rows.length + 1 > budget` boundary so a regression to
  >= would be caught instead of silently truncating when there is room.

- ThinkingViewer.test (new): pin that the modal wheel handler subscribes WITH
  bypassVpGate: true (mirror of the HistoryItemDisplay test that pins the
  opposite contract), so a future refactor dropping the flag can't silently
  break wheel scrolling in non-VP mode.

`11 >= 11` is true (windowing fires a spurious "+1 more"). The not.toContain(

On macOS, terminals in the default "Option as compose character" mode
(iTerm2 "Normal", VS Code without macOptionIsMeta) turn Option+t into the

Option was held — the "expand thinking" shortcut silently typed "†" into the
prompt instead of toggling. Terminals that speak the Kitty keyboard protocol
(e.g. Ghostty) report a real Alt+t event, which is why it already worked there.

Rewrite a lone "†" to a synthetic Alt+t in the keypress pipeline. This both
fires TOGGLE_THINKING_EXPANDED and, via the meta flag, stops the glyph from
being inserted into the input buffer, so it behaves exactly like Alt+t. Scoped
to darwin to avoid affecting legitimate "†" input on other platforms.

b2f11b7351 fix(cli): prevent scroll snap-back and flicker in non-VP mode during multi-agent runs (#5799)
* fix(cli): re-measure footer when LiveAgentPanel grows to stop non-VP overflow flicker (#5798)

In non-VP mode the dynamic (non-<Static>) region is repainted in place; once
it is taller than the terminal, every repaint forces the view back to the
bottom with a flicker. The pending region is supposed to be clipped to
availableTerminalHeight = terminalHeight - controlsHeight - ..., but
controlsHeight was measured by a useLayoutEffect whose dependency list did not
reflect the LiveAgentPanel roster.

The panel renders inside mainControlsRef and grows as agents launch, yet its
only self-driven re-render is a per-second elapsed-time tick that never changes
the roster. So controlsHeight went stale on agent launch, availableTerminalHeight
was left too large, and the pending region overflowed the terminal.

Add getLiveAgentPanelLayoutKey (mirrors the existing stickyTodosLayoutKey) and
feed it into the controlsHeight measurement effect's deps, so the footer is
re-measured exactly on height-affecting roster changes (agent add/remove/status,
panel focus) and stays stable across the elapsed-time tick. All growth events
already flow through BackgroundTaskViewState.entries, which AppContainer
consumes, so this adds no extra render churn. Time-based eviction only shrinks
the panel (safe over-reservation) and is intentionally not tracked.

Tests: unit-test the key (changes on growth/shrink/status/focus, stable across
ticks) and a runtime reproduction using real ink render + measureElement showing
the reserved room goes stale without the dep and re-measures with it.

* test(cli): cover all isLiveAgentPanelVisibleEntry branches; condense duplicated rationale

Address review on #5799:
- AppContainer: condense the call-site comment to a cross-reference; the full

- liveAgentPanelVisibility.test: add the missing branches for
  isLiveAgentPanelVisibleEntry — non-agent → false, running/paused → true,
  terminal agent missing endTime → false (guards NaN from nowMs - undefined).

* test(cli): add source-level guard for the controlsHeight measurement dep

Address @wenshao's review on #5799: the one-line fix (liveAgentPanelLayoutKey
in the controlsHeight measurement-effect deps) had no regression guard — the
behavioural tests exercise the mechanism on a stand-in component, and removing
the dep left all of them green.

A render-based guard against the real AppContainer is not feasible:
ink-testing-library's rerender remounts AppContainer (re-running mount effects
regardless of deps) and an external setState does not flush ink's reconciler,
so the missing-dependency update path is unobservable. Add a source-level
assertion instead — it fails if liveAgentPanelLayoutKey is dropped from the
measurement effect's dependency array (verified: removing the dep turns the
guard red), so a deps cleanup or exhaustive-deps autofix can't silently revert
the fix.

7a1b244d34 fix(cli): drop input box & user-message background fills (#5772)
The TUI paints no background of its own and relies on the terminal's own
background. Two elements broke that and rendered as off-colour blocks that
could not be made consistent across terminals and themes:

- The input box (#5568) flood-filled theme.background.primary. Even when
  the theme's light/dark bucket matched the terminal (the #5746 gate), the
  exact colour usually differed from the terminal's real background, so the
  prompt rendered as a distinct block — worst over SSH/remote where
  brightness detection is unreliable and defaults to dark.

- The user-message half-line band (#4595) painted a subtleBandColor band
  behind each user message, gated on the same theme/terminal match. Because
  history is rendered through Ink <Static> (committed rows are never
  repainted) and the gate only fires when the active theme matches the
  terminal, the band showed on some messages but not others across a theme
  switch — it cannot be made consistent.

Stop painting both so the input area and user messages blend into the
terminal background everywhere. User messages fall back to marginTop=1 for
separation. The software cursor now derives its contrast from the
terminal's detected brightness (getEffectiveTerminalBackground) so it stays
visible with no fill painted.

Also remove the band's now-unused helpers — subtleBandColor and
supportsTrueColor (added by #4595) and the dead UserMessageProps.width prop.

Fixes #5771.

receive nothing — mouse scroll was dead in VP mode.

Fix: KeypressContext's existing SGR swallowing code now buffers the
readline-fragmented sequence, reconstructs it, parses via
parseSGRMouseEvent, and forwards to registered mouse subscribers.
useMouseEvents subscribes through this channel instead of ink's useInput.

* refactor(core): F2 PR A R9 — McpClientManager options-object ctor

R9 (filed as F2 follow-up from #4336 review): 7 positional ctor args
collapse to (config, toolRegistry, options?: McpClientManagerOptions).
The trailing 5 (eventEmitter, sendSdkMcpMessage, healthConfig,
budgetConfig, pool) become named fields on `McpClientManagerOptions`.
Test factory `mkManager(overrides?)` introduced at the top of
`mcp-client-manager.test.ts` so each of the prior 80 inline
constructions becomes a single line naming only the field(s) the test
overrides; the 4 `undefined` sentinels each test threaded through to
reach the trailing `pool` arg are gone.

Net: 113 LOC removed (test) + 35 LOC added (src exposes interface +
mkManager factory + tool-registry call site update). Behavior
unchanged — same field assignments, same downgrade-enforce-without-
budget breadcrumb, same budget event wiring.

Filed bucket: F2 perf / cleanup PR A (R9 + W11 + W12 + R10/R23 T7),
see issue #4175 item 7 "F2 post-merge cleanup PRs". This is the first

Test sweep: 84/84 mcp-client-manager.test.ts pass; typecheck clean.

* refactor(core): F2 PR A W11 — extract attachPooledSession + rollbackReservationOnSpawnFailure

W11 (filed as F2 follow-up from #4336 review): two private helpers
on `McpTransportPool` to eliminate inline duplication in `acquire()`:

  - `attachPooledSession(entry, id, serverName, cfg, sessionId,
    toolReg, promptReg)`: builds `SessionMcpView` + `entry.attach`
    with the standard pool release callback. Used by both the
    fast-path attach (existing entry) and the post-spawn attach
    (after `await inFlight`). NOT used by `createUnpooledConnection`
    — its release callback runs `entry.forceShutdown('manual')` +
    `indexDetach` directly (no pool refcount accounting since
    unpooled entries are per-session).

  - `rollbackReservationOnSpawnFailure(reservationResult, serverName)`:
    R24 T17 contract — only release the budget slot if THIS acquire
    actually reserved a new slot (`'reserved'`); `'already_held'`
    skips because the sibling owns it. Used by both the unpooled
    catch and the pooled spawn-in-flight catch.

Race-window invariants (W10 / W77 / W90 / W111 / W125 / R24 T17)
stay at the call sites because they describe the SURROUNDING
ordering, not the helpers themselves. Helpers are documented to
defer those decisions back to callers.

Behavior unchanged. Filed bucket: F2 perf cleanup PR A (R9 done /
W11 this commit / W12 + R10 to follow).

Test sweep: 28/28 mcp-transport-pool.test.ts pass; typecheck clean.

* refactor(core): F2 PR A W12 — SessionMcpView precompute filter Sets

W12 (filed as F2 follow-up from #4336 review): `applyTools` /
`applyPrompts` precompute `excludeSet` + `includeSet` once per pass
instead of scanning `cfg.includeTools` / `cfg.excludeTools` arrays
inside every per-tool iteration.

Pre-fix the per-tool predicate (`passesSessionFilter`) walked both
arrays for every snapshot entry → O(M × N) per `applyTools` call.
With M tools × N filter entries, typical M=5-20 / N=2-5 case
finishes in microseconds either way; the win is data-structure
correctness and code clarity, not perceived perf.

`passesSessionFilter` / `passesSessionPromptFilter` (the array-
based predicates) stay exported and unchanged for unit tests + any
caller wanting to test a single name without paying Set construction.
The bulk path uses two new private helpers `compileNameFilter` +
`compiledFilterAccepts` whose Sets live on the `applyTools` /
`applyPrompts` stack frame.

Same semantics: `excludeTools` is direct-equality match (no parens
strip — pre-F2 behavior preserved); `includeTools` strips the first
`(...)` suffix so `toolName(args)` matches `toolName`.

* perf(core): F2 PR A R10 / R23 T7 — pid-descendants ps snapshot + pgrep fallback

R10 / R23 T7 (filed as F2 follow-up from #4336 review): the Linux
/ macOS pid-descendant enumeration moves from per-pid `pgrep -P
<pid>` BFS (one subprocess fork per node visited) to a single
`ps -A -o pid=,ppid=` snapshot followed by an in-memory tree walk
over `Map<ppid, pid[]>`. Windows analog: single `Get-CimInstance
Win32_Process | ConvertTo-Csv` snapshot of all `(ProcessId,
ParentProcessId)` rows replaces per-pid
`Get-CimInstance -Filter "ParentProcessId=$p"` BFS.

Two motivations:
  1. **Fork count**: typical `npx → tool` / `uvx → tool` wrapper
     trees are 2-3 levels deep with B=1-3 children per node →
     pre-fix BFS forked ~5-10 subprocesses per pool-shutdown call.
     Post-fix: exactly 1 fork regardless of tree depth.
  2. **Snapshot consistency**: pre-fix BFS walked the table level
     by level; a child that forked between two adjacent BFS levels
     could be missed (we'd see the child but query its
     descendants AFTER the new fork). The snapshot path captures
     the table at one instant; new descendants forked after the
     snapshot are tolerated by the existing ESRCH-tolerant
     SIGTERM loop.

Caveats:
  - `ps -A -o pid=,ppid=` is POSIX standard (macOS / Linux /
    *BSD), but BusyBox `ps` <v1.28 (2018) doesn't support `-o`.
    Distroless containers may not have `ps` at all. To preserve
    behavior on those edge platforms, the legacy per-pid `pgrep`
    BFS is retained as a fallback (`listDescendantPidsUnixPgrepFallback`).
    Same retention on Windows for the per-pid filter path.
  - Snapshot path uses `maxBuffer: 8MB` to cover ~250k-process
    pathological hosts. Default 1MB would clip at ~30k processes.
  - `MAX_DESCENDANTS = 256` / `MAX_DEPTH = 8` caps preserved on
    both snapshot + fallback paths.
  - Snapshot scans the entire host process table (not just the
    target subtree). On the typical 200-500 process developer
    machine this parses in <10ms; the win over BFS is real but
    not order-of-magnitude — ~2x improvement, not 100x. PR A's
    motivation framing is "fork hygiene + consistency", not raw
    perf.

Empty-result detection: snapshot path tracks `parsedRows`. If the
ps/CIM tool runs successfully but produces 0 parseable rows
(BusyBox without `-o` echoing usage, AppLocker truncating CIM
output, etc.), we throw — the outer catch falls back to the
per-pid path. A genuine "root has no children" case parses many
rows and just returns empty from the walk. So the
"no-children-found" semantics are preserved across both paths.

Test gate update: pre-fix `integration: spawn-and-enumerate` test
skipped on `CI === '1'` because pgrep wasn't available on
minimal CI runners. Post-fix `ps -A` is universally available on
non-distroless Linux/macOS — only the Windows skip remains.
6/6 pid-descendants tests pass including the now-active
integration spawn test.

Design doc (`docs/design/f2-mcp-transport-pool.md` §6.4 + the F2
follow-up table at lines 82-85) updated to reflect the snapshot
+ fallback shape, and to mark W11 / W12 / R9 / R10 as ✅ Done in
PR A with the per-fix commit refs.

This commit completes F2 cleanup PR A. Filed bucket order:
R9 (commit 0cb1eaa27) → W11 (commit 2d546efca) → W12 (commit
a4a855ab3) → R10 (this commit). Issue #4175 item 7 "F2 post-
merge cleanup PRs": PR A done; PR B (W93 + W133-a + W134) and
PR C (W133-c SDK breaking) to follow as separate clusters.

Test sweep: 287/287 F2 + cli pass; ESLint clean; typecheck clean
(core + cli). Integration test on macOS local runs the new
snapshot path successfully.

* refactor(core): F2 PR A R2 — wenshao followup (visited set + dedup predicate)

Two Suggestions from wenshao's first PR #4411 review pass (07:15Z),
both small and worth folding before merge:

PR-A-R2 #1 (pid-descendants.ts:309 — walkDescendants visited set):
  `walkDescendants`'s BFS lacked a `visited` set. If the snapshot
  captures a PID-reuse cycle — rare but possible on busy hosts with
  rapid pid churn between `ps -A`'s start and parse, where Linux
  wraparound can show a freed pid in a different parent's children
  list creating an A→B / B→A cycle — pre-fix BFS would revisit nodes
  and fill the MAX_DESCENDANTS=256 quota with duplicate entries,
  starving legitimate descendants. Pre-PR-A the per-pid `pgrep` BFS
  had the same theoretical issue but was less exposed (each
  `pgrep -P pid` call returns only DIRECT children; snapshot captures
  the whole tree at once, making cycles instantly visible).

  Fix: 3-LOC `Set<number>` add. `root` seeded into `visited` so a
  malformed snapshot listing root as a descendant of its own child
  doesn't re-enqueue root either.

PR-A-R2 #2 (session-mcp-view.ts:117 — predicate dedup):
  After W12, the exported `passesSessionFilter` /
  `passesSessionPromptFilter` still called `passesNameFilter` (the
  pre-W12 array-based implementation), while `applyTools` /
  `applyPrompts` used `compiledFilterAccepts(compileNameFilter(...))`.
  Two parallel implementations of the same predicate — future change
  to one without the other would silently diverge:
    - the exported function's tests (passesSessionFilter unit tests)
      would still pass
    - the production filter path in applyTools/applyPrompts would
      behave differently

  Reviewer also noted `passesSessionPromptFilter` had zero callers
  in production code or tests after W12 — `applyPrompts` no longer
  references it. Kept the export rather than deleting it (matches
  the `passesSessionFilter` shape for symmetry + the F3 audit-path
  comment block earmarks both as the replay predicates), but routed
  both through `compiledFilterAccepts(compileNameFilter(...))` so
  there is a single source of truth. Set construction is per-call
  for these exports (negligible for unit-test / one-off probes);
  the bulk paths in `applyTools` / `applyPrompts` still construct
  ONE filter per pass via the original W12 code path.

`passesNameFilter` (the standalone array-based helper) deleted —
its only callers were the two exports, which now use the compiled
path. Public-API surface unchanged: the two exported functions
keep their signatures and semantics.

Test sweep: 19/19 pid-descendants + session-mcp-view tests pass;
typecheck + ESLint clean.

* fix(core): F2 PR A R3 T3 — Windows CSV delimiter locale fix

`ConvertTo-Csv -NoTypeInformation` honors the system locale's list
separator on PowerShell 5.1. On German / French / Dutch / Italian /
... locales the separator is `;` not `,`, so the regex
`^"(\d+)","(\d+)"$` in `snapshotProcessTreeWin` never matched →
`parsedRows === 0` → snapshot threw → fell back to the per-pid CIM
filter path with ~0.5-1s extra PowerShell startup latency per
descendant on every pool shutdown.

Fix: 1-LOC `-Delimiter ","` on `ConvertTo-Csv`. Forces comma
regardless of locale or PowerShell version. PowerShell 7+ defaults
to comma already; 5.1 (the Windows-bundled version most users have
without explicit upgrade) honored locale. The explicit delimiter
makes both consistent.

Skipped wenshao's companion Suggestion T4 (test coverage for
walkDescendants MAX_DESCENDANTS / MAX_DEPTH caps) as F2 hardening
follow-up — the caps are simple 2-line guards exercisable by
inspection; ~50 LOC of mock infrastructure isn't commensurate
with the regression risk on currently-stable defensive code,
and (per the issue #4175 follow-up bucket) we keep dedicated
test-coverage work out of perf-cleanup PRs.

* refactor(acp-bridge): F1 test split — lift bridge.test.ts (6861 LOC) to acp-bridge (#4445)

* refactor(acp-bridge): rename httpAcpBridge.test.ts -> bridge.test.ts (git mv)

Pure file rename; zero content change. Follow-up commits will:
- extract FakeAgent + makeChannel + makeBridge into testUtils.ts
- split 4 daemon-host integration tests back to cli/daemonStatusProvider.test.ts

Part of #4175 F1 test split (deferred from #4334).

* refactor(acp-bridge): extract testUtils + split daemon-host tests to cli (#4175 F1)

Net mechanical extraction following commit 2aff1a4d1 (pure git mv of
httpAcpBridge.test.ts -> bridge.test.ts). After this commit
`@qwen-code/acp-bridge` owns the bulk of the lifted bridge test
suite, and cli keeps only the 4 daemon-host integration tests that
need to wire `createDaemonStatusProvider()`.

Changes:

1. New `packages/acp-bridge/src/internal/testUtils.ts` (~280 LOC):
   FakeAgent, FakeAgentOpts, ChannelHandle, makeChannel, makeBridge
   (no statusProvider default — acp-bridge tests exercise the
   no-provider fallback path), WS_A/WS_B/SESS_A constants. Marked
   @internal; lives under `internal/` matching the existing
   `stderrLine.ts` package-private convention. Exposed via new
   `./internal/testUtils` subpath in package.json exports.

2. `packages/acp-bridge/src/bridge.test.ts` shrinks from 6861 ->
   ~6400 LOC: fixtures replaced with named imports from
   `./internal/testUtils.js`; cross-package import
   `from './daemonStatusProvider.js'` removed (4 daemon-host tests
   moved out); ACP SDK + bridgeErrors / workspacePaths / bridge /
   channel / bridgeTypes imports split into multiple statements
   reflecting actual post-F1 provenance.

3. New `packages/cli/src/serve/daemonStatusProvider.test.ts`
   (~240 LOC, 4 tests): wires real `createDaemonStatusProvider()`
   through a cli-side `makeBridge` wrapper to assert end-to-end
   daemon env / preflight cells. Imports
   `createHttpAcpBridge` via the `./httpAcpBridge.js` re-export
   shim — doubles as a shim surface smoke check.

Verification:
- acp-bridge: 291/291 tests pass (177 in bridge.test.ts).
- cli: daemonStatusProvider.test.ts 4/4 pass; full cli suite 6742/6767
  green (16 pre-existing failures in AuthDialog / memoryDiagnostics /
  useAtCompletion — all on `daemon_mode_b_main` baseline, last
  modified by commits predating this branch).
- Tests counts pre-split: 181 in httpAcpBridge.test.ts;
  post-split: 177 in bridge.test.ts + 4 in daemonStatusProvider.test.ts
  = 181 (parity preserved).

Part of #4175 F1 test split (deferred from #4334).

* refactor(acp-bridge): self-review round 1 — vitest alias + doc/comment polish

Five code-reviewer findings folded in on top of e97282f30:

S1 [Suggestion] — Test-utils ships to npm + cli reads stale dist.
  Added `packages/cli/vitest.config.ts:resolve.alias` mapping
  `@qwen-code/acp-bridge/internal/testUtils` → the .ts source. The
  package subpath export is RETAINED (required for TypeScript
  `nodenext` to resolve types — it won't fall back to tsconfig
  paths once exports rejects a subpath). Dual-channel approach
  documented in the testUtils JSDoc, including the alpha-stage 0.0.1
  tradeoff that the file still ships in dist (stripInternal /
  .npmignore deferred).

S2 [Suggestion] — Stale wording "two tests" in narrative comment.
  bridge.test.ts split-marker now correctly says "4 fallback tests"
  (no-provider × 2 surfaces + throwing-provider × 2 surfaces).

S3 [Suggestion] — "Shim smoke check" only half-applied.
  daemonStatusProvider.test.ts now routes `BridgeOptions` and
  `HttpAcpBridge` types through `./httpAcpBridge.js` shim too
  (alongside `createHttpAcpBridge`), so the entire factory surface
  the cli tests rely on flows through the F1 re-export shim.

N1 [Nit] — Asymmetric split-marker phrasing.
  Both markers now describe the 4 moved tests by surface
  (env real / preflight idle / preflight merged-live /
  preflight extMethod-throws) rather than "1 of" + "3 more".

N2 [Nit] — testUtils "the suite" ambiguity.
  makeChannel JSDoc now references `bridge.test.ts` explicitly
  instead of "the suite" (which was unambiguous pre-split when
  helpers + 10 createInMemoryChannel sites lived in the same file).

Verification: 291/291 acp-bridge tests pass; 4/4 cli daemon
integration tests pass; tsc clean on both packages (pre-existing
server.ts errors on baseline unchanged); eslint --max-warnings 0
clean on all 4 touched files.

* docs(cli): self-review round 2 — fix stale vitest.config.ts alias comment

Round 2 reviewer caught a 3-way contradiction in the round 1 docs:
- vitest.config.ts said: alias replaces the export, internal/* stays
  unpublished (matches stderrLine convention).
- package.json: subpath export IS declared.
- testUtils.ts JSDoc: both channels intentionally retained,
  testUtils ships in dist.

Round 1 explicitly chose to retain the export because TS `nodenext`
won't fall back to tsconfig `paths` once `exports` rejects a
subpath; the alias only serves to short-circuit *runtime* resolution
so cli reads src/ not dist/. Rewriting the vitest.config.ts comment
to reflect that dual-channel reality (and pointing readers at
testUtils.ts for the full rationale).

* fix(acp-bridge): #4445 round 3 fold-in — 4 of 7 reviewer threads adopted

PR #4445 review pass — 4 adopt + 3 decline (declines replied
inline; not folded here):

ADOPTED:

T1 [copilot daemonStatusProvider.test.ts:136 — bridge.shutdown
   missing]: added `await bridge.shutdown()` to test 2 (preflight
   idle). Three of four tests already shut down; symmetry +
   future-proof if `createHttpAcpBridge` gains background work
   even when no channel was spawned.

T5 [wenshao testUtils.ts:92 — makeBridge naming collision]: cli-
   side helper renamed `makeBridge` -> `makeBridgeWithDaemonStatusProvider`
   (4 call sites in daemonStatusProvider.test.ts), JSDoc updated to
   reference the wenshao thread. testUtils.makeBridge stays as the
   canonical name used by ~100 tests in bridge.test.ts. A future
   contributor can no longer pick the wrong helper by accident.

T6 [wenshao testUtils.ts:32 — JSDoc mis-claims @internal tag matches
   stderrLine.ts convention]: fixed wording. stderrLine.ts uses prose
   only; @internal is an additional package-private signal, not a
   convention match. Also restructured the npm-leak paragraph to
   describe the new .npmignore-via-files-negation enforcement (T7).

T7 [wenshao package.json:70 — testUtils ships to npm]: switched
   `files: ["dist"]` -> `files: ["dist", "!dist/internal/testUtils.*",
   "!dist/**/*.test.*"]`. Wenshao's suggested `"test"` exports
   condition wasn't viable: vitest sets `vitest` not `test`, and
   gating on `vitest` would hide types from the cli's tsc compile.
   The negation-pattern files-field excludes the built testUtils
   from the publish surface while keeping the subpath export entry
   that TypeScript `nodenext` needs to resolve types. Verified via
   `npm pack --dry-run`: dist/internal/stderrLine.* still ships
   (production internal helper); dist/internal/testUtils.* +
   dist/**/*.test.* are excluded.

DECLINED (replied on PR threads, not folded here):

T2/T3 [copilot — `handles` array unused in tests 3/4]: bookkeeping
   matches the pre-split bridge.test.ts verbatim; cleanup is scope
   creep on this rename PR.

T4 [copilot — testUtils eager-imports createHttpAcpBridge,
   cross-copy identity risk]: cli daemonStatusProvider.test.ts uses
   its OWN local `makeBridgeWithDaemonStatusProvider` and never
   imports testUtils.makeBridge — the cross-copy concern isn't
   triggered. Premature abstraction on a test-only fixture.

Verification: 291/291 acp-bridge tests pass; 4/4 cli daemon tests
pass; tsc clean both packages; eslint --max-warnings 0 clean on
2 touched .ts files; `npm pack --dry-run` confirms publish-surface
exclusions.

* fix(core): F2 cleanup PR B — self-heal observability (W133-a + W134) (#4460)

* fix(core): F2 cleanup PR B — self-heal observability (W133-a + W134)

W93 declined as already satisfied by W1 fix in #4336 commit 6
(spawnEntry's catch already calls forceShutdown which runs the full
cleanup table — listener removal, timer clear, subscriber detach,
sweep+disconnect, onClosed eviction). Source-verified non-repro.

W133-a: McpClient.onerror now captures the error in a private
`lastTransportError` field (reset at each connect()); the W120
silent-drop block at mcp-pool-entry.ts:346 reads it via the new
`getLastTransportError()` getter and appends `: <error.message>` to
the lastError string on the emitted 'failed' event. Preserves the
literal "silent transport drop" prefix invariant for log-grep
backward compat — pre-fix marker stays a substring.

W134: sweepAndDisconnect now returns SweepResult instead of void —
{ pidSweepError?, disconnectError?, descendantsFound?,
descendantsSignaled? }. The silent-drop fire-and-forget caller chains
to inspect the result and emits a structured warn log when either
pid-sweep threw OR sigtermPids partially signaled (signaled < found)
— surfaces orphan-process pressure without inflating PR scope (no
new SSE event or SDK reducer state; deferred to W134-followup if
maintainers want metrics).

forceShutdown / doRestart sweep callers ignore the return value (JS
implicit-void at await sites preserves behavior).

4 new tests in mcp-transport-pool.test.ts covering W133-a happy path
+ fallback (no prior onerror) + W134 pidSweepError + W134
partial-signal failure modes. Module-mocks pid-descendants.js for
controllable sweep behavior, and debugLogger.js to observe warn
calls (production logger is session-gated and a no-op in tests).
Singleton-stub debugLogger mock so production module-load
`createDebugLogger('McpPool:Entry')` and the test's retrieval get
the same vi.fn instances.

Verification:
- tsc clean: packages/core, packages/cli (server.ts pre-existing
  errors unchanged)
- F2 transport-pool: 32/32 pass (28 pre-existing + 4 new)
- mcp-client: 46/46 pass
- eslint --max-warnings 0 clean on 3 touched files

Part of #4175 #4336 follow-up bucket.

* fix(core): #4460 round 1 fold-in — 4 copilot doc/comment threads adopted

T1 [copilot mcp-pool-entry.ts:116 — stale line ref in SweepResult JSDoc]:
  replaced `mcp-pool-entry.ts:383` with stable method-anchor reference
  to the W120 silent-drop block inside `statusChangeListener`. Line
  numbers drift on every edit; method names don't.

T2 [copilot mcp-pool-entry.ts:453 — `?? 0` ambiguous in warn payload]:
  silent-drop warn log now prints `descendantsFound=unknown` and
  `descendantsSignaled=unknown` when the values are undefined (only
  reachable in the pidSweepError branch — sweep threw before
  assignment). Operators triaging the warn can now distinguish
  "sweep succeeded but found 0 descendants" from "sweep itself
  threw, count is genuinely unmeasured". Locked in via a new
  assertion in the W134 pidSweepError test.

T3 [copilot mcp-client.ts:116 — brittle line refs in lastTransportError
  JSDoc]: replaced `mcp-pool-entry.ts:346` and `mcp-client.ts:130`
  with stable method/block names (the `statusChangeListener` silent-
  drop block; the `client.onerror` arrow inside connect()). Same
  fix applied to the parallel comment in mcp-transport-pool.test.ts:730
  for consistency.

T4 [copilot mcp-transport-pool.test.ts:797 — singleton-stub mock comment
  contradictory]: rewrote the comment to unambiguously describe what
  the mock DOES (factory body runs once; inner arrow returns the same
  object on every call) instead of the prior hypothetical phrasing
  ("Returning a fresh object would have...") which read as a
  description of current behavior at first glance.

All 4 are doc/comment fixes — zero behavior change apart from the
T2 string format ('unknown' instead of '0'). Verified:
- 32/32 mcp-transport-pool.test.ts pass
- tsc clean on packages/core
- eslint --max-warnings 0 clean on 3 touched files

* fix(core): #4460 round 2 fold-in — remove dead SweepResult.disconnectError field

T5 [wenshao mcp-pool-entry.ts:134 — `disconnectError` is dead data]:
  glm-5.1 review caught that the field was populated when
  `client.disconnect()` threw (line 844) but no consumer ever read
  it — the silent-drop `.then()` handler gated only on
  `pidSweepError` and partial-signal; `forceShutdown` and `doRestart`
  ignore the return; no test asserted on it.

Removed the field from `SweepResult` and the assignment in the
disconnect catch. The pre-existing `debugLogger.error(`client.disconnect
failed for ...`)` inside `sweepAndDisconnect` already gives operators
the signal — adding it to the outer silent-drop warn would have been
duplicate noise. If a future consumer needs to gate logic on disconnect
failures, re-add the field + reader at that point.

Verification: 32/32 mcp-transport-pool.test.ts pass; tsc + eslint
clean on the touched file.

* feat(sdk/daemon-ui): unified completeness follow-up to #4328 (#4353)

* feat(sdk/daemon-ui): expand event coverage to 28+ daemon event types (PR-A)

Closes the "12+ daemon events fall through to debug" gap surfaced in the PR
the daemon currently emits (Stage 1 + Wave 3-4), so renderers stop having
to peek at `rawEvent.data` for known event categories.

Session-meta:
- session.metadata.changed (from session_metadata_updated)
- session.approval_mode.changed (from approval_mode_changed)
- session.available_commands (from available_commands_update; upgraded
  from a status-text fallback to a typed event carrying the command list)

Workspace state (Wave 3-4):
- workspace.memory.changed
- workspace.agent.changed
- workspace.tool.toggled
- workspace.initialized
- workspace.mcp.budget_warning
- workspace.mcp.child_refused
- workspace.mcp.server_restarted
- workspace.mcp.server_restart_refused

Auth device-flow (Wave 4 OAuth, RFC 8628):
- auth.device_flow.started
- auth.device_flow.throttled
- auth.device_flow.authorized
- auth.device_flow.failed (carries DaemonAuthDeviceFlowSdkErrorKind)
- auth.device_flow.cancelled

- `DaemonUiErrorEvent.errorKind?: DaemonErrorKind` — closed-enum error
  category propagated from daemon's typed-error taxonomy. Renderers can
  branch on errorKind for "retry auth" vs "check file path" affordances
  instead of regex-matching `text`.
- `DaemonUiToolUpdateEvent.provenance?: DaemonUiToolProvenance` +
  `.serverId?` — closed enum ('builtin' | 'mcp' | 'subagent' | 'unknown').
  Falls back to the `mcp__<server>__<tool>` naming heuristic when the
  daemon doesn't stamp provenance explicitly. Unblocks UI namespace
  dispatch without string-matching toolName.

Session-meta / workspace / auth events do NOT push transcript blocks.
They are intentional sidechannel observations: `lastEventId` advances
(monotonic invariant preserved), but the chat-stream transcript stays
focused on user/assistant/tool/shell/permission content. Renderers
consume them via selectors (introduced in follow-up PRs).

All new event types produce short structured lines in
`daemonUiEventToTerminalText` for tail-style debug consumers. Web/IDE
renderers should consume the typed events directly via subscription.

40/40 tests pass. New tests verify:
- All 16 new event types normalize correctly
- Malformed payloads fall back to debug without leaking raw data
  (`secret` field never appears in fallback text)
- MCP tool provenance heuristic (`mcp__github__create_issue` →
  provenance='mcp', serverId='github')
- errorKind propagation on session_died / stream_error
- Reducer is no-op on new event types; lastEventId still advances

This is PR-A of the unified-renderer-layer follow-up series:
- PR-A (this commit) — event coverage + closed-enum schema
- PR-B — server-side timestamps + ordering refactor
- PR-C — multimodal content + tool preview taxonomy
- PR-D — render contract (toMarkdown / toHtml / toPlainText) + adapter
  conformance test framework
- PR-E — reducer state machine (subagent / progress / current tool /
  cancellation propagation)

See https://github.com/QwenLM/qwen-code/pull/4328#issuecomment-4494179724

* feat(sdk/daemon-ui): server timestamps + event-id-based ordering (PR-B)

Closes the "时间定义不标准" gap surfaced in the PR #4328 review:
- Client-side `Date.now()` drifts across clients
- No daemon-authoritative timestamp propagated to UI
- Out-of-order replay events get fresher `state.now` than originals,
  breaking `createdAt` ordering

- `DaemonUiEventBase.serverTimestamp?: number` — daemon-authoritative
  wall-clock timestamp extracted from envelope.
- `DaemonTranscriptBlockBase.serverTimestamp?: number` + `clientReceivedAt: number`.
- `createdAt` preserved as `@deprecated` alias for `clientReceivedAt`
  (backward compat for code written before this PR).

`extractServerTimestamp` looks at three candidate envelope locations:

1. `event.serverTimestamp` (preferred when daemon adds it)
2. `event._meta.serverTimestamp` (Anthropic-style metadata convention)
3. `event.data._meta.serverTimestamp` (sessionUpdate nested location)

The SDK is ready to consume serverTimestamp WHEN daemon emits it, without
requiring a coordinated SDK release. Undefined when daemon doesn't emit
(current state) — graceful degradation to client-clock ordering.

`selectTranscriptBlocksOrderedByEventId(state)` — returns blocks sorted by:

1. `eventId` (daemon-monotonic SSE cursor) — primary key
2. `serverTimestamp` (daemon wall clock) — fallback for synthetic frames
3. `clientReceivedAt` (local clock) — last resort

Use this when displaying long sessions where event id 5 may arrive AFTER
event id 7 (typical in SSE replay-after-reconnect).

`formatBlockTimestamp(block, opts)` — formats the most authoritative
timestamp on a block using `Intl.DateTimeFormat`. Prefers
`serverTimestamp` over `clientReceivedAt` for cross-client consistency.
Accepts locale / timeZone / dateStyle / timeStyle.

Daemon needs to stamp `_meta.serverTimestamp` on every SSE envelope. This
SDK PR is ready to consume it the moment the daemon ships the field; no
coordination needed.

- serverTimestamp extraction from all three envelope locations
- Defaults undefined when envelope has none
- `selectTranscriptBlocksOrderedByEventId` sorts mixed-arrival events by
  eventId (replay scenario)
- `formatBlockTimestamp` prefers serverTimestamp; returns localized string

PR-B of the unified follow-up to PR #4328 (PR-A + PR-B + PR-C + PR-D +
PR-E in one branch).

* feat(sdk/daemon-ui): reducer state machine — currentTool / approvalMode / cancellation propagation (PR-E)

Closes the "reducer state machine 设计缺漏" gap surfaced in the PR #4328 review:
- No `currentTool` — UI scans `blocks[]` to find the running tool
- No mirrored approval mode — UI walks events to badge "plan"/"yolo"
- Cancellation does not propagate — in-flight tool blocks stuck at
  'in_progress' forever when the parent prompt is cancelled

## State additions (sidechannel, no transcript blocks)

`DaemonTranscriptSidechannelState`:
- `currentToolCallId?: string` — toolCallId of the in-flight tool
- `approvalMode?: string` — mirrored from session.approval_mode.changed
- `toolProgress: Record<string, { ratio?, step? }>` — per-tool progress
  shape (daemon-side emission of `tool.progress` events pending)

## Reducer behavior

### `tool.update` events

`IN_FLIGHT_TOOL_STATUSES` = { pending, confirming, running, in_progress }
`TERMINAL_TOOL_STATUSES` = { completed, success, failed, error, canceled, cancelled }

- Tool enters in-flight: set `currentToolCallId = event.toolCallId`
- Tool enters terminal: clear `currentToolCallId` if it matches
- Unknown status (forward-compat): leave pointer untouched

This avoids the failure mode where a future daemon-emitted status like
`'paused'` would silently mark unknown states as either in-flight or
terminal incorrectly.

### `session.approval_mode.changed`

Mirror `event.next` onto `state.approvalMode`. Renderers can render a
mode badge ("plan" / "default" / "auto-edit" / "yolo") with a single
selector call, no event-stream walking.

### `assistant.done` with `reason === 'cancelled'`

`propagateCancellationToInFlightTools` walks every tool block whose
status is still in-flight and force-sets it to 'cancelled'. The daemon
does not guarantee terminal `tool_call_update` for every in-flight tool
when the parent prompt is cancelled, so this propagation prevents UI
spinners from spinning forever.

`currentToolCallId` is also cleared in the same call.

Non-cancellation `assistant.done` (e.g., `reason: 'end_turn'`) does NOT
propagate — in-flight tools remain in-flight until the daemon emits
their terminal update naturally.

## Selectors

- `selectCurrentTool(state)` — returns the running tool block, or undefined
- `selectApprovalMode(state)` — returns the mirrored approval mode
- `selectToolProgress(state, toolCallId)` — per-tool progress query

All exported from `@qwen-code/sdk/daemon`.

## Scope deliberately deferred

Subagent nesting (`parentBlockId` / `delegationId` / `DaemonSubagentTranscriptBlock`)

* feat(sdk/daemon-ui): tool preview taxonomy + multimodal content extraction (PR-C)

Closes two related gaps surfaced in the PR #4328 review:
- `DaemonToolPreview` had only 4 kinds — UI fell back to `key_value` /
  `generic` for tools that deserved structured display
- `getTextContent` silently dropped non-text content (image / audio /
  resource), so multimodal conversations vanished from the UI

`DaemonToolPreview` extends from 4 to 8 variants:

- `file_diff` — `{ path, oldText?, newText?, patch? }` — file edit tools
  (Anthropic-style `oldText/newText`, aider-style `patch`, write-style
  `newText` alone)
- `file_read` — `{ path, range?: [start, end] }` — file read tools, with
  range extracted from `lineRange` tuple OR `offset/limit` pair
- `web_fetch` — `{ url, method? }` — HTTP fetch tools (requires URL
  with scheme to avoid false positives on relative paths)
- `mcp_invocation` — `{ serverId, toolName, argsSummary? }` — MCP server
  tool calls, identified via `mcp__<server>__<tool>` naming convention
  (same heuristic as PR-A `DaemonUiToolUpdateEvent.provenance`)

Detector order matters — MCP wins first (most specific), then file_diff,
file_read, web_fetch, then the existing command / key_value fallbacks.

New helper `extractContentPart(value): DaemonUiContentPart | undefined`
returns a discriminated union:

```ts
type DaemonUiContentPart =
  | { kind: 'text'; text: string }
  | { kind: 'image'; mediaType: string; source: { url?, data? } }
  | { kind: 'audio'; mediaType: string; source: { url?, data? } }
  | { kind: 'resource'; uri: string; mediaType?, description? };
```

The existing `getTextContent` is preserved for backward compat. Renderers
that need to surface non-text content (web UI thumbnails, IDE attachment
chips) now have a typed shape to consume.

- Wiring `extractContentPart` into the normalizer / reducer so text
  blocks accumulate `parts: DaemonUiContentPart[]` alongside `text`
  (additive shape change requires render contract coordination — PR-D).
- 5 additional tool preview kinds (image_generation / code_block /
  tabular / subagent_delegation / search) — useful but not urgent;
  current 8 kinds cover the typical agent flows.

- file_diff detection from Anthropic / aider / write shapes
- file_read with lineRange tuple AND offset+limit pair
- web_fetch with method, REJECTS relative paths (no scheme)
- mcp_invocation with serverId + toolName extraction
- Detector priority: MCP wins over file_diff on conflicting shapes
- extractContentPart for text / image (url) / audio (data) / resource
- Unknown content type returns undefined (skip rather than synthesize)
- Image without source returns undefined (defensive)

* feat(sdk/daemon-ui): render contract — markdown / HTML / plain text helpers (PR-D)

Closes the "render 契约只覆盖 terminal" gap surfaced in the PR #4328 review:

> PR ships `daemonUiEventToTerminalText` for terminal. Web/IDE/channel
> adapters each roll their own projection. No shared contract → adapter
> divergence is inevitable.

## New helpers

```ts
daemonBlockToMarkdown(block, opts?): string  // GFM-compatible
daemonBlockToHtml(block, opts?): string      // conservatively escaped HTML
daemonBlockToPlainText(block, opts?): string // for copy-paste / logs
daemonToolPreviewToMarkdown(preview, opts?): string
```

All three respect the same `kind` discrimination so adapters can switch
between them without touching call sites.

## Per-kind projection

For each `DaemonTranscriptBlock['kind']`:

- `user` / `assistant` / `thought` — plain text with role labels
- `tool` — header with toolName + structured preview + status badge
- `shell` — fenced code block, stream-discriminated (stdout vs stderr)
- `permission` — title + options list + resolved/pending indicator
- `status` / `debug` / `error` — semantic class / role (error → role=alert)

For each `DaemonToolPreview['kind']`:

- `ask_user_question` — question + options as bullet list
- `command` — fenced bash with optional cwd comment
- `file_diff` — unified diff in fenced code block (oldText/newText OR patch)
- `file_read` — `path (lines N-M)` line
- `web_fetch` — `METHOD url` line
- `mcp_invocation` — `serverId::toolName` with args summary
- `key_value` — bullet list
- `generic` — emphasized summary

## Security

- Default HTML sanitizer escapes `<`, `>`, `&`, `"`, `'` and FIRST strips
  ANSI/control sequences via `sanitizeTerminalText` (defense against
  agent-emitted escape codes in HTML output).
- Custom sanitizer hook for consumers wanting markdown→HTML pipelines
  (markdown-it + DOMPurify, etc.).
- `sanitizeUrls` option strips token-like query params (`token=`, `key=`,
  `x-amz-`, etc.) from URLs in `web_fetch` previews.
- `maxFieldLength` truncation defaults 8192, prevents pathological
  rendering on huge content.

## Adapter conformance (out of scope for this commit)

The conformance test framework (fixture corpus + `runAdapterConformanceSuite`)
mentioned in PR-D scope is deferred to a follow-up. The render helpers
here are the precondition — once stable, the conformance framework can
use them as the reference projection.

## Test coverage (77/77 pass)

- All 9 block kinds render in markdown (verified for user/assistant/tool/
  shell/permission/error specifically)
- file_diff renders as unified diff with old/new lines
- mcp_invocation renders as `server::tool` format
- HTML escapes XSS (`<script>` → `&lt;script&gt;`)
- HTML strips terminal escape sequences before escaping
- Error blocks emit `role="alert"` for screen readers
- plain text drops markdown delimiters
- maxFieldLength truncates with ellipsis
- sanitizeUrls strips token query params
- Custom sanitizer hook works

## Roadmap

PR-D of the unified follow-up to PR #4328 — completes the 5-PR series
(A: event coverage, B: time schema, E: state machine, C: tool preview +
content extraction, D: render contract).

* feat(sdk/daemon-ui): 5 additional tool preview kinds — taxonomy complete (PR-F)

Closes the "5 additional preview kinds" item in PR #4353's TODO §A
(SDK-only work).

## New preview kinds (8 → 13)

- `code_block` — `{ language?, code, origin? }` — REPL / formatter /
  generator output, fenced as `\`\`\`<language>` in markdown
- `search` — `{ query, resultCount?, top? }` — grep / ripgrep / find /
  glob results with up to 5 top hits
- `tabular` — `{ columns, rows, totalRows? }` — structured table output
  (50-row cap with `totalRows` truncation indicator); supports both
  `columns: string[] + rows: unknown[][]` explicit shape and legacy
  `data: Array<Record<>>` shape (auto-infers columns from first row)
- `image_generation` — `{ prompt, thumbnailUrl?, model? }` — dall-e /
  diffusion / imagen / flux / sora style tools
- `subagent_delegation` — `{ agentName, task, parentDelegationId? }` —
  Anthropic-style Task tool and similar sub-agent dispatchers

## Detector priority

Order matters — most specific wins. New detectors slot in between
`mcp_invocation` and `file_diff`:

```
mcp_invocation > subagent_delegation > search > image_generation
  > file_diff > file_read > web_fetch > code_block > tabular
  > command > key_value > generic
```

Rationale: subagent / search / image generation are most discriminable
(distinct toolName patterns); file ops next; code_block / tabular last
because their shapes (`code:`, `columns:`) can appear in other tools.

## Render projections

Both `daemonToolPreviewToMarkdown` and the plain-text rendering paths
extended with cases for all 5 new kinds:

- code_block: fenced markdown code block with language tag
- search: bold header + GFM bullet list of top results
- tabular: GFM pipe table with header / separator / body / truncation hint
- image_generation: bold header + blockquoted prompt + embedded markdown
  image (URL sanitization respected via `sanitizeUrls` opt)
- subagent_delegation: bold delegate-arrow header + blockquoted task +
  optional parent delegation reference

## Test coverage (91/91 pass, +14 new)

- Each detector with positive case
- Detector priority verified: subagent_delegation wins over file_diff
  when toolName='Task' has both subagent + file-edit fields
- Tabular row cap (50) + totalRows stamping for truncated data
- Legacy data: Array<Record<>> auto-column inference
- Each render projection with structural assertions (markdown table
  format, image embed, bullet lists)

## Roadmap

PR-F of the unified follow-up to PR #4328. Brings the preview taxonomy
to 13 kinds covering: file ops (3), web (1), code/data (2), media (1),
agent control (2 — ask_user_question + subagent_delegation), MCP (1),
search (1), generic fallbacks (2).

* feat(sdk/daemon-ui): adapter conformance framework + fixture corpus (PR-G)

Closes the "Adapter conformance test framework" item in PR #4353's TODO §A.
Lets any daemon-ui adapter (TUI / web / IDE / channel / mobile) validate
that it projects a fixed corpus of daemon SSE event streams to the same
semantic shape — catches projection drift before it reaches users.

## API surface

```ts
interface DaemonUiAdapterUnderTest {
  reduce(events: readonly DaemonUiEvent[]): unknown;
  renderToText(state: unknown): string;
}

interface DaemonUiConformanceFixture {
  name: string;
  description: string;
  envelopes: DaemonEvent[];           // raw daemon envelopes
  expectedContains: string[];          // phrases the rendered text MUST contain
  expectedAbsent?: string[];           // phrases that MUST NOT appear
  normalizeOptions?: { ... };          // forward-compat normalize opts
}

runAdapterConformanceSuite(adapter, opts?): ConformanceSuiteResult
DAEMON_UI_CONFORMANCE_FIXTURES: ReadonlyArray<DaemonUiConformanceFixture>
```

## Design

**Format-agnostic assertion**: adapters can render to ANSI / HTML /
markdown / JSX — the framework only inspects plain text via
`renderToText`. Catches semantic divergence (missing user message,
wrong tool status, leaked secret) without forcing identical formatting.

**Embedded fixture corpus** (no fs reads — works in browser bundle):
- `simple-chat` — user/assistant streaming flow
- `tool-call-lifecycle` — running → completed transition
- `file-edit-diff` — file_diff preview surfacing
- `mcp-invocation` — MCP serverId/toolName extraction via heuristic
- `permission-lifecycle` — request + resolved with outcome
- `mcp-budget-warning` — Wave 3 event (adapter must observe but rendering
  is its choice)
- `cancellation-propagates` — tool block status flows
- `malformed-payload-redaction` — uses `includeRawEvent: true` to verify
  even a debug-mode adapter doesn't leak `token: secret-do-not-leak`
- `auth-device-flow-success` — Wave 4 OAuth events
- `available-commands-typed-event` — PR-A upgrade from status text

Per-fixture `expectedContains` and `expectedAbsent` describe the
content contract independently of format.

## Suite result

```ts
{
  passed: number,
  failed: ConformanceFailure[],   // each carries missing + leaked + excerpt
  total: number,
}
```

**Does not throw** — caller asserts on `result.failed` so adapter test
suites can produce per-fixture diagnostics rather than a single opaque
exception.

## Filter options

`only` / `skip` allow targeted runs during adapter development:

```ts
runAdapterConformanceSuite(myAdapter, { only: ['simple-chat'] });
runAdapterConformanceSuite(myAdapter, { skip: ['cancellation-propagates'] });
```

## Test coverage (97/97 pass, +6 new)

- SDK reference adapter (reducer + markdown render) passes all fixtures
- SDK reference adapter (reducer + plainText render) also passes
- Buggy adapter (empty string output) fails every fixture with non-empty
  `expectedContains`
- Buggy adapter (raw event dump via JSON.stringify) caught by redaction
  fixture's `expectedAbsent`
- `only` filter narrows to a single fixture
- `skip` filter excludes named fixtures from the corpus

## Usage from adapter authors

```ts
// In your adapter's test file
import { runAdapterConformanceSuite } from '@qwen-code/sdk/daemon';
import { reduceForTui, renderTuiState } from './my-tui-adapter';

it('TUI adapter conforms to daemon UI corpus', () => {
  const result = runAdapterConformanceSuite({
    reduce: reduceForTui,
    renderToText: renderTuiState,
  });
  expect(result.failed).toEqual([]);
});
```

## Roadmap

PR-G of the unified follow-up to PR #4328. The corpus is intentionally
small (10 fixtures) but extensible — adapter authors can submit new
fixtures via additions to `DAEMON_UI_CONFORMANCE_FIXTURES` to lock in
regression coverage for edge cases their adapter encountered.

* feat(webui+sdk/daemon-ui): wire transcriptAdapter to SDK render contract (PR-H)

Closes the "WebUI transcriptAdapter migration" item in PR #4353's TODO §A.
Validates the PR-D render contract end-to-end on the real WebUI consumer.

`daemonTranscriptToUnifiedMessages(blocks, options?)` gains a new options
parameter:

```ts
interface DaemonTranscriptAdapterOptions {
  useMarkdown?: boolean;                  // default: false
  enrichToolDetailsWithPreview?: boolean; // default: false
}
```

Defaults preserve legacy behavior — existing callers see no change.

For `user` / `assistant` / `thought` blocks, content is projected via
SDK's `daemonBlockToMarkdown` instead of raw sanitized text. The WebUI's
markdown renderer (markdown-it) then gets:

- `**You**\n\n<content>` for user blocks (bold "You" label)
- Raw text for assistant blocks (markdown formatting in agent output
  passes through cleanly)
- `> *thought:* <text>` blockquote for thought blocks

For `tool` blocks, `rawOutput` is replaced with `daemonToolPreviewToMarkdown(block.preview)`.
This lets WebUI surfaces without per-preview-kind React components still
display:

- `file_diff` as a fenced unified diff
- `mcp_invocation` as `server::tool` with args summary
- `tabular` as GFM pipe table
- `search` as bullet list with match count
- `image_generation` as embedded markdown image
- `subagent_delegation` as delegate arrow + task quote

Renderers with per-kind components should leave this opt-out.

`packages/sdk-typescript/src/daemon/index.ts` was missing exports for
PR-D / PR-F / PR-G / PR-B / PR-E surface — WebUI's `@qwen-code/sdk/daemon`
import path uses the daemon root, not the ui/ sub-index. Added 15+
re-exports so consumers don't need to use the longer
`@qwen-code/sdk/daemon/ui/index.js` path.

Now exported from `@qwen-code/sdk/daemon` root:
- `daemonBlockToMarkdown` / `daemonBlockToHtml` / `daemonBlockToPlainText`
- `daemonToolPreviewToMarkdown`
- `extractContentPart` + `DaemonUiContentPart` type
- `formatBlockTimestamp` + `selectTranscriptBlocksOrderedByEventId`
- `selectCurrentTool` / `selectApprovalMode` / `selectToolProgress`
- `runAdapterConformanceSuite` + `DAEMON_UI_CONFORMANCE_FIXTURES`
- All associated types

`webui/src/daemon/transcriptAdapter.test.ts` mock blocks updated to include
`clientReceivedAt` (required field added in PR-B). Mechanical change —
every `createdAt: N` test fixture gets a matching `clientReceivedAt: N`.

- WebUI `npm run typecheck` — clean
- SDK `npm run typecheck` — clean
- SDK `vitest run test/unit/daemonUi.test.ts` — 97/97 pass

* fix(daemon-ui): address review feedback

* fix(daemon-ui): address review hardening feedback

* fix(daemon-ui): handle resync-required events

* feat(sdk/daemon-ui): consume daemon-side subagent nesting context (PR-K)

Closes the SDK-side gap for §B1 in PR #4353's TODO list. PR-E originally
deferred subagent nesting because daemon-side parent-context wasn't yet
stamped on tool_call events. After the rebase onto current
daemon_mode_b_main, source verification confirms the daemon now emits
`tool_call._meta.parentToolCallId` + `tool_call._meta.subagentType` via
`SubAgentTracker.getSubagentMeta()` (core), so the SDK side is unblocked.

## Schema additions (additive, forward-compat-safe)

`DaemonUiToolUpdateEvent`:
  - parentToolCallId?: string  — toolCallId of the parent Task / delegation
  - subagentType?: string      — sub-agent type label (e.g. 'code-reviewer')

`DaemonToolTranscriptBlock`:
  - parentToolCallId?: string  — mirror of event field
  - subagentType?: string      — mirror of event field
  - parentBlockId?: string     — pre-resolved by reducer when parent already
                                 in state, so renderers don't re-correlate

## Normalizer wiring

`normalizeToolUpdate` checks both top-level and `_meta` for parentToolCallId
+ subagentType (fallback chain mirrors how provenance/serverId are read).
Top-level tool calls without sub-agent context omit the fields cleanly.

## Reducer behavior

- New tool block: resolves `parentBlockId` from `toolBlockByCallId` at
  create time. Out-of-order arrival (child before parent) leaves
  `parentBlockId` undefined — selectors fall back to `parentToolCallId`
  lookup.
- Existing tool block update: adopts parent context if not yet
  correlated, never overwrites established correlation (handles the
  flow where SubAgentTracker activates after the initial tool_call).

## New public selectors

- selectSubagentChildBlocks(state, parentToolCallId): returns the
  array of tool blocks invoked inside a given parent delegation
- isSubagentChildBlock(block): type guard for "this tool block came
  from a sub-agent"

Both exported from @qwen-code/sdk/daemon root + ui/index.

## Forward-compat properties

- Top-level tool calls (no sub-agent) work identically as before
- Trimmed parent blocks: child fallback to undefined parentBlockId
- Daemon emits both fields together; SDK reads independently to tolerate
  partial future stamping

## Test coverage (129/129 pass, +5 new tests)

- Extract parentToolCallId + subagentType from `_meta`
- Top-level tool calls have undefined parent fields (forward-compat)
- Reducer correlates parentBlockId at create time
- Reducer adopts parent context on later update (out-of-order arrival)
- isSubagentChildBlock discriminator

## Roadmap

PR-K of the unified follow-up to PR #4353. Closes §B1 (subagent nesting)
in the TODO declaration; daemon-side already shipped on
`daemon_mode_b_main` via SubAgentTracker (core).

* fix(daemon-ui): PR-K self-review hardening — back-fill / trim / self-ref / docs

Multi-round self-review of PR-K (d8375fe46) surfaced two real bugs, a
few defensive gaps, and missing docs/fixture coverage. All addressed
in one commit.

## Bugs fixed

### Bug 1 — `parentBlockId` never back-filled for out-of-order arrival

Original PR-K resolved `parentBlockId` only at child create time, which
broke this flow:

  1. Child arrives WITH parent stamp → block created with
     `parentToolCallId` set, `parentBlockId` undefined (parent not in
     state yet)
  2. Parent arrives later → block created, `toolBlockByCallId` indexed
  3. Subsequent child updates: existing-block branch only ran the
     back-fill inside `!existing.parentToolCallId`, which is false (we
     already adopted the stamp in step 1). `parentBlockId` stayed
     undefined forever.

Fix: separate the two correlations.
  - existing-block update: independently back-fill `parentBlockId`
    whenever `parentToolCallId` is set and `parentBlockId` is missing
  - new-block create: scan existing children whose `parentToolCallId`
    matches the new block's `toolCallId` and back-fill their
    `parentBlockId`. Cheap O(n) over current blocks.

### Bug 2 — dangling `parentBlockId` after trim

`trimTranscriptState` reset `toolBlockByCallId[id]` to the trimmed
sentinel for evicted blocks but did NOT walk surviving children to
null their `parentBlockId` references. Renderers walking
`blockIndexById.get(parentBlockId)` would get undefined, with no
"why" signal.

Fix: post-trim, walk remaining tool blocks; if `parentBlockId`
references an id not in `keptIds`, null it. `parentToolCallId` stays
(survives trimming so selector-keyed queries still work).

## Defensive hardening

- **Self-reference guard** (normalizer): drop
  `parentToolCallId === toolCallId` before it reaches the reducer.
  Daemon should never emit this, but defending costs nothing.
- **Selector docstring**: clarify `selectSubagentChildBlocks` returns
  **direct** children only; document cycle / depth-cap responsibility
  for renderers walking up the chain.
- **Cosmetic**: remove redundant `as DaemonToolTranscriptBlock` cast
  in `isSubagentChildBlock` (TypeScript already narrows after
  `block.kind === 'tool'` on the discriminated union).
- **Alphabetical**: move `isSubagentChildBlock` re-export to correct
  position in both `daemon/index.ts` and `daemon/ui/index.ts`.

## Docs + conformance gaps closed

- `README.md` — new "Sub-agent nesting (PR-K)" section with full
  reducer behavior, out-of-order handling note, recursive walk example,
  cycle-defense note.
- `MIGRATION.md` — new step 8a with before/after for nested rendering.
- `conformance.ts` — new `subagent-nesting` fixture covering parent +
  nested child via `tool_call._meta`. Markdown-safe phrases chosen
  (markdown escapes `-` so titles cannot be substring-matched as-is).

## Test coverage (+5 tests, 134/134 pass)

- Self-reference dropped in normalizer
- Back-fill on out-of-order parent arrival (child first, parent after)
- Back-fill on later child update when parent now exists
- Dangling `parentBlockId` nulled after parent trimmed
- New `subagent-nesting` conformance fixture passes SDK reference adapter

## Side-effect verification

Verified no regressions:
- Cancellation propagation still cancels parent + children together
  (iterates `toolBlockByCallId`, which includes both)
- Render contract unchanged (`daemonBlockToMarkdown` etc. project per
  block, no nested awareness required)
- No serializer to update
- `selectTranscriptBlocksOrderedByEventId` unaffected (parent-agnostic)

* fix(daemon-ui): permission block trim contract — wenshao review

Addresses both items from wenshao's review on PR #4353:

## Critical — resolvePermissionBlock missing TRIMMED guard

The sibling `upsertPermissionBlock` (transcript.ts:544) correctly returns
early when `existingId === TRIMMED_PERMISSION_BLOCK_ID`, but
`resolvePermissionBlock` (transcript.ts:581) had no such guard. When
`maxBlocks` trimming evicted a pending permission request, a subsequent
`permission.resolved` event would:

1. Fail the `getWritableBlockById` lookup (sentinel is not a real block id)
2. Fall through and create a brand-new orphan resolution block

This wasted a block slot, accelerated further trimming, and silently
broke the trimmed-block contract that the request-side guard establishes.

Fix: mirror the request-side guard. Read the index entry up front,
return early on the sentinel.

## Suggestion — permissionBlockByRequestId grows unboundedly

`trimTranscriptState` writes `TRIMMED_PERMISSION_BLOCK_ID` for evicted
permission requests but never deletes those entries. Unlike the tool
side (which calls `pruneTrimmedToolIndexes` post-trim), the permission
index grew without bound in long sessions.

Fix: add `pruneTrimmedPermissionIndexes` analogous to the tool-side
helper. Caps the sentinel set at `maxBlocks` entries; older entries are
deleted (any later resolution event still drops cleanly via the new
Critical guard).

## Tests

- Updated existing `keeps orphan permission resolutions visible after
  request trimming` test to encode the corrected contract (drops silently
  instead of creating an orphan). Test rename: "drops resolution for
  trimmed permission requests (wenshao Critical)".
- New `Suggestion: pruneTrimmedPermissionIndexes caps the trimmed
  sentinel set` test verifies the cap.

Total: 136/136 tests pass, SDK + WebUI typecheck green.

## Side-effect verification

- `upsertPermissionBlock` already had the equivalent guard — no
  asymmetry remains.
- `pruneTrimmedPermissionIndexes` only touches entries holding the
  sentinel; live permission blocks are unaffected.
- Selectors over `state.blocks` (e.g. `selectPendingPermissionBlocks`)
  iterate the block array, not the index — unaffected by cap.

* fix(daemon-ui): address wenshao + doudouOUC inline reviews (2026-05-23)

Addresses the 13 inline review comments from wenshao (6) and doudouOUC
(7, one overlap) on the 2026-05-23 review round.

## Critical / Important

### sanitizeUrls not threaded through HTML preview path (doudouOUC)

`daemonBlockToHtml` for tool blocks called `daemonToolPreviewToPlainText`
which didn't accept `opts` — when callers set `sanitizeUrls: true`, the
markdown path stripped auth tokens but the HTML path leaked them into
the DOM. Now: helper accepts opts, threads through `web_fetch.url` and
`image_generation.thumbnailUrl`.

### enrichToolDetailsWithPreview overwrote rawOutput (doudouOUC)

The webui adapter replaced structured `rawOutput` with a markdown
summary string when `enrichDetails: true`. Downstream `ToolCallData`
consumers may branch on the shape (object vs string) and break. Plus
the actual tool output was silently dropped.

Fix: keep `rawOutput` verbatim, surface markdown via a new optional
`previewMarkdown` field added to `ToolCallData`.

### transcriptBlockToTerminalText zero test coverage (wenshao)

Added 12 tests covering each `switch` branch (user / assistant / thought
/ tool / shell stdout+stderr / permission unresolved+resolved / status /
debug / error) plus the unknown-kind degradation path. Verified
`assertNever` returns a graceful error line (does NOT throw) — wenshao's
reviewer was slightly wrong on the throw claim but coverage gap was
real.

### selectTranscriptBlocksOrderedByEventId no memoization (wenshao)

Selector was called from React `useSyncExternalStore` and re-sorted on
every dispatch — including sidechannel-only events that don't touch
blocks. Added WeakMap cache keyed on `state.blocks` reference; the
reducer preserves the same array reference for non-block-mutating
events, so the cache hits across renders.

### selectSubagentChildBlocks O(n) per call (wenshao)

Naive `state.blocks.filter()` was O(n) per call; rendering a tree with
m parents made it O(n*m). Built a memoized reverse index keyed on
`state.blocks` reference (WeakMap of parentToolCallId →
DaemonToolTranscriptBlock[]). Each lookup now O(1) after first call.

### Test file TS errors at root tsc (wenshao)

Fixed multiple TS errors in `daemonUi.test.ts` flagged by root
`tsc --noEmit`:
- Added `DaemonTranscriptState` + `DaemonUiEvent` imports
- `block.content` access via `as Array<Record<string, unknown>>` cast
- `delete` on globalThis property via narrower interface cast
- `debug?.text` via `DaemonUiEvent & { text: string }` narrowing (Extract on
  union with `'status' | 'debug'` literal would resolve to never)
- 6 occurrences of index-signature access via bracket notation
- `raw: null` added to 3 `DaemonUiPermissionOption` literals (required field)
- Explicit type annotations on conformance-suite `renderToText` params

Note: `webui/src/daemon/transcriptAdapter.test.ts` shows residual
"clientReceivedAt does not exist" errors at root tsc, but this is
environmental — the resolution trace shows `@qwen-code/sdk/daemon`
crossing into a sibling worktree's stale dist via shared workspace
node_modules. In a single-worktree CI checkout this resolves cleanly.

## Suggestions (cleanups)

### Hoist asDaemonErrorKind double-eval (doudouOUC)

`session_died` + `stream_error` cases each computed `asDaemonErrorKind`
twice in the conditional spread (predicate + value). Hoisted to const,
no functional change.

### renderToolHeader bypassed opts (doudouOUC)

Forwarded `opts` so `maxFieldLength` is honored for tool title /
toolName / toolKind.

### isSensitiveKey duplicates (doudouOUC)

Removed duplicate `endsWith('accesskey')` / `endsWith('secretkey')`
checks and the redundant exact-match `privatekey` (already covered by
`endsWith`).

### propagateCancellationToInFlightTools iterated trimmed (wenshao)

Filter `TRIMMED_TOOL_BLOCK_ID` sentinels up front. Avoids redundant
index dereferences in long sessions with many historical tools.

### toolProgress shallow clone (doudouOUC + wenshao)

`cloneTranscriptState` outer `...state` spread shared inner
`{ ratio?, step? }` references between snapshots. Once `tool.progress`
event handlers start mutating in place, the prior snapshot would leak.
Deep-clone the inner records now (cost bounded by in-flight tools,
small).

### isDeviceFlowErrorKind closed set (wenshao + doudouOUC)

Both reviewers suggested strict validation. We INTENTIONALLY kept
lenient pass-through — the public type
`DaemonAuthDeviceFlowSdkErrorKind` explicitly includes `(string & {})`
as a forward-compat escape hatch (existing test `keeps future
auth_device_flow_failed errorKind values observable` enforces this).
Now expose `KNOWN_DEVICE_FLOW_ERROR_KINDS` as documentation and
explain the design in the JSDoc.

## Validation

| | |
|---|---|
| SDK tests | 148/148 pass (+12 terminal coverage + assorted hardening) |
| SDK typecheck | clean |
| WebUI typecheck | clean |

## Side-effect verification

- WeakMap memos invalidate correctly: reducer creates a fresh
  `state.blocks` reference only on block-mutating events. Sidechannel
  events reuse the same reference.
- `previewMarkdown` is optional and additive on `ToolCallData`;
  consumers ignoring it are unaffected.
- `sanitizeUrl` is called only when `opts.sanitizeUrls === true` in HTML
  path; default behavior unchanged.

* fix(daemon-ui): wenshao glm-5.1 review — lazy COW + lint + memo verification

Addresses the 6 inline comments from wenshao's 2026-05-23 13:03
CHANGES_REQUESTED review.

## Real fix — WeakMap memoization actually works now (Suggestion #2)

The earlier `sortedBlocksCache` / `childrenIndexCache` WeakMaps keyed on
`state.blocks` reference, but `cloneTranscriptState` did
`blocks: [...state.blocks]` eagerly — every dispatch produced a fresh
array, so the caches never hit. The JSDoc claim "memoize across renders
that don't touch blocks" was misleading.

Fix: lazy copy-on-write.

- `cloneTranscriptState` now shares `blocks` + `blockIndexById` by
  reference (no eager copy).
- New `takeBlocksOwnership(state)` performs the array copy at the first
  mutation; subsequent mutations in the same dispatch are no-ops
  (tracked via module-level `ownedBlocks: WeakMap<State, blocks>`).
- `appendBlock`, `getWritableBlockById`, and `trimTranscriptState` all
  take ownership before mutating.

Result: sidechannel events (approval mode change, session metadata,
workspace events, auth device-flow, etc.) preserve `state.blocks`
identity across dispatches. The WeakMap caches actually hit now —
verified by new test `selectTranscriptBlocksOrderedByEventId returns
the same array reference for sidechannel-only events`.

## Lint Criticals (3) — readonly array syntax

`ReadonlyArray<T>` → `readonly T[]` per `@typescript-eslint/array-type`:

- `KNOWN_DEVICE_FLOW_ERROR_KINDS` satisfies clause
- `EMPTY_CHILD_LIST`
- `selectSubagentChildBlocks` return type

## Suggestion #1 — shallow copy from selectSubagentChildBlocks

Return `[...cached]` so accidental in-place mutation (e.g., caller
calling `.sort()` on the result) cannot corrupt the WeakMap-cached
children index for other consumers sharing the same `state.blocks`
snapshot.

## Suggestion #6 — KNOWN_DEVICE_FLOW_ERROR_KINDS sync test

Added test `only contains canonical device-flow error kinds` — runtime
assertion that guards against the array being silently emptied. The
`as const satisfies readonly DaemonAuthDeviceFlowSdkErrorKind[]` at the
declaration site already enforces type-level membership; this test
adds a stable count check.

## Test coverage (+4 new tests, 152/152 pass)

- `selectTranscriptBlocksOrderedByEventId` preserves array identity
  across sidechannel-only events (memo hit verification)
- `selectSubagentChildBlocks` preserves WeakMap entry across sidechannel
  dispatches
- `selectSubagentChildBlocks` returns shallow copy (caller mutation
  doesn't corrupt cache)
- `KNOWN_DEVICE_FLOW_ERROR_KINDS` membership + count assertions

## Side effects

- Block property mutations still leak across snapshots (pre-existing —
  the original eager copy was also a shallow array copy with shared
  block refs). Not introduced by this change; documented in
  `getWritableBlockById` comments.
- All existing block-mutating tests pass — `takeBlocksOwnership` produces
  the same observable result as eager copy, just deferred to first
  mutation.

Validation:
- SDK tests: 152/152 pass
- SDK typecheck: clean
- WebUI typecheck: clean

wenshao review 4350741340 (2026-05-23 13:00): the prior doudouOUC
review fixed only the HTML path; the plainText tool case still called
`daemonToolPreviewToPlainText(block.preview)` without `opts`, so
`sanitizeUrls` + `maxFieldLength` were silently ignored when consumers
used the plain-text projection (logs, clipboard, terminal mirroring).

* fix(daemon-ui): address wenshao 2026-05-23 reviews (3 Critical + 8 Suggestion + 1 false-positive)

Walks all 22 inline comments from wenshao's 13:00-14:56 burst plus
doudouOUC's APPROVED-with-suggestion. 11 real fixes applied; 1 reverted
after gate-check; remaining items either already addressed in prior
commits (stale) or are test-only coverage gaps now filled.

## Security / Correctness Criticals (real)

### sanitizeUrl strips Basic Auth (R2 #1)

`https://user:pw@host/...` previously passed through with userinfo
intact, leaking secrets into rendered markdown / HTML / plaintext.
`u.username = ''; u.password = '';` before serializing.

### thumbnailUrl protocol validation always-on (R2 #2)

`javascript:alert(1)` in `![image](url)` survived when sanitizeUrls
was false (the default). Added `ensureSafeImageUrl(url)` — protocol
whitelist (http/https/data only) that runs unconditionally for image
URL renderings. `sanitizeUrls: true` still wins for query-param +
Basic Auth stripping.

### permission.resolved orphan after sentinel pruned (R1 #2)

The prior trim-contract fix guarded `existingId === TRIMMED_*`. After
`pruneTrimmedPermissionIndexes` deleted a sentinel (long sessions),
`existingId` became `undefined`, bypassed the guard, and created an
orphan. Reject `undefined || TRIMMED_*` together.

## Behavior Suggestions (real)

### Selective cancellation propagation (R2 #6)

`assistant.done.reason` of `stream_ended` / `reconnected` are
transport-layer signals — the daemon-side tool is still running and SSE
replay will deliver the real terminal status. Marking in-flight tools
cancelled caused a visible spinner-to-red flash on reconnect. Scoped
propagation to `cancelled` || `error` only.

### awaitingResync diagnostics (R2 #3)

State-resync latch silently dropped events with no signal. Added
`console.warn` describing the dropped event type + last resync trigger
so a stuck UI is debuggable. Latch behavior intentionally preserved —
recovery is `store.reset()` on session reconnect.

### selectSubagentChildBlocks: freeze instead of copy (R1 #8)

`[...cached]` per-call defeated React.memo / useMemo identity
stability (every call produced a fresh array reference). Now freeze
the cached arrays at build time in `getOrBuildChildrenIndex` and
return the frozen reference directly — referential stability +
mutation defense (strict-mode throws on `.length = 0` etc.).

### detectSubagentDelegation regex too broad (R3 #2)

`(?:^|_)task$` falsely matched `edit_task` / `list_task` /
`create_task` etc. — common tool names unrelated to delegation.
Anthropic's Task tool is literally named `Task` (no prefix), so
restricted bare-`task` to whole-name only: `^task$`. `delegate` /
`subagent` / `spawn_task` keep the `^|_` prefix.

### memoryChanged bytesWritten finite check (R3 #3)

`typeof === 'number'` accepted NaN / Infinity. Use the existing
`numberField` helper which calls `Number.isFinite(v)`.

### Multi-line blockquote prefix (R3 #1)

`> *thought:* ${text}` only prefixed the first line; subsequent lines
escaped the blockquote. Added `blockquote(raw)` helper that prefixes
every line; applied to thought / debug / error renderings.

## Quality (real)

### plainText / HTML maxFieldLength parity (R1 #5/6/7, doudouOUC approve note)

The tool block in markdown caps via `text()`; plaintext + HTML caps
were missing on header fields, preview content, and permission block
labels. Threaded `cap()` consistently across all three projections.

### isSensitiveKey dedup (R1 #10)

Seven exact-match entries (`password` / `apikey` / `idtoken` /
`sessiontoken` / `clientsecret` / `xapikey` / `xauthtoken`) were
already subsumed by existing `endsWith` rules. Removed.

### Re-export DaemonUiStateResyncRequiredEvent (R2 #7)

Other session-meta event types are exported from the daemon barrel;
this one was missed. Added to both `daemon/ui/index.ts` and
`daemon/index.ts`.

## Reverted after gate-check (false-positive)

### classifySelectedPermissionOption CANCELLED branch (R2 #4)

Reviewer suggested adding `CANCELLED_PERMISSION_TERMS` check before
the `completed` default, so `selected:cancel` would map to cancelled.
This CONFLICTS WITH:
- the design comment at the caller: "A selected option resolves the
  prompt even when the option id is a domain value like a city name or
  an option id containing deny/cancel"
- the existing test `'cancelled-substring-permission'` with payload
  `'selected:abort'` expecting status `'completed'`

The daemon expresses "user cancelled the prompt" via `cancelled` as the
PRIMARY token (handled at the caller layer), not `selected:cancel` —
the latter means "user picked an option labeled cancel", which is a
successful selection. Reverted; added explanatory comment so the next
review round doesn't re-flag it.

## Stale (already fixed)

### R1 #1 (daemonBlockToPlainText opts forwarding)

Already fixed in d35cbb75a (2026-05-23 monitor pass for review
4350741340). No further action.

## Test coverage added

- HTML web_fetch URL sanitization (sanitizeUrls + Basic Auth)
- Image URL protocol validation when sanitizeUrls:false
- HTML shell / permission / thought / debug / status block kinds
- Trimmed-tool cancellation propagation (no throw + transport-layer no-cancel)
- Late permission.resolved after sentinel prune (no orphan)
- Frozen children-index identity stability + mutation guard
- previewMarkdown preserves rawOutput as object (in webui adapter test file)

Modern browsers don't execute `<img src="data:text/html,...">`, but

over-claimed the protection.

* fix(daemon-ui): wenshao + doudouOUC R4 review batch

Walks 6 wenshao items (delivered as 8 review submissions — 2 CHANGES_REQUESTED
+ 6 individual COMMENTED — but 6 distinct concerns) and 3 doudouOUC R4
nits. All 9 real issues addressed; no false-positives this round.

## Real Criticals

### awaitingResync recovery API (wenshao R4)

`store.reset()` requires session-id change semantics — wrong shape for
"same-session reconnect with SSE replay" recovery. Added explicit
`store.clearAwaitingResync()` API. Latch is still set on receipt of
`session.state_resync_required` (intentional one-way during replay
window); consumers now have a clean path to clear after the replay
stream drains.

### normalizeAuthDeviceFlowCancelled test coverage (wenshao R4)

Coverage gap surfaced — happy path (valid deviceFlowId) and malformed
fallback to debug both untested. Added 2 tests.

## Real Suggestions

### sanitizeUrl: AWS / Azure / GCP credential patterns

The previous regex caught `x-amz-` and `x-goog-` headers + generic
`signature` / `sig`, but missed:
- `AWSAccessKeyId` (S3 presigned)
- Azure SAS short codes (`sv` / `se` / `sr` / `sp` / `st` / `spr` /
  `sip` / `ss` / `srt` / `sig` / `skoid` / etc.)
- GCP signed-URL `GoogleAccessId` + `Expires` (paired with credentials
  in signed URL contexts)

Widened regex to include `aws|google|expires` prefixes + added explicit
Azure-SAS Set check.

### detectFileDiff: `content` alias disambiguated

`{ path, content }` was being classified as `file_diff` regardless of
tool semantics — but the same shape is common for file_read assertions
or search queries. Since detectFileDiff runs BEFORE detectFileRead in
the detector chain, this caused mis-classification.

Fix: restrict bare `content` to require either (a) write-intent tool
name (write/create/edit/replace/save/update) OR (b) co-occurrence with
`oldText`. Explicit `newText` / `new_text` / etc. still pass through
unconditionally. Required adding `opts` to the `detectFileDiff`
signature (callers already pass opts to siblings).

### detectFileRead: 0-based offset → 1-based range

Type doc says `range: [startLine, endLine]` is 1-based inclusive. The
offset+limit conversion produced 0-based output ([0, 9] for
offset=0/limit=10), which displayed as "lines 0-9" — line 0 doesn't
exist in 1-based. Convert at the detector: `[offset+1, offset+limit]`.

Updated the matching test (which had encoded the 0-based bug as
expected behavior).

### formatMissedRange — guard inverted / single-event ranges

The naive `lastDeliveredId+1 .. earliestAvailableId-1` formula
produced:
- `gap === 0`: "missed 6-5" (inverted)
- `gap === 1`: "missed 6-6" (single event shown as range)

Added `formatMissedRange()` helper with explicit branches:
- `last < first` → "no events lost (resync requested without gap)"
- `last === first` → "missed 1 daemon event (id N)"
- `last > first` → "missed daemon events X-Y"

Applied in both `transcript.ts` (status block message) and `terminal.ts`
(ANSI projection) — same formula was duplicated.

## doudouOUC R4 nits

### README errorKind list outdated

Replaced `expired / transport / server / internal` with pointer to
`KNOWN_DEVICE_FLOW_ERROR_KINDS` exported constant — canonical list
auto-stays-in-sync.

### README "10 scenarios" stale

Was 10, became 11 with subagent-nesting. Removed the count and let
the corpus be derived at runtime via
`DAEMON_UI_CONFORMANCE_FIXTURES.length`.

### selectTranscriptBlocks danger post lazy-COW

With state.blocks now shared across sidechannel snapshots, a misbehaving
consumer doing `(state.blocks as DaemonTranscriptBlock[]).sort()` would
poison every snapshot sharing the reference. Freeze the blocks array
at the dispatch boundary in `reduceDaemonTranscriptEvents`. Internal
reducer mutation goes through `takeBlocksOwnership` which copies before
mutating, so the frozen reference is never modified in place.

* fix(daemon-ui): wenshao R5 review batch — Critical OAuth fragment leak + 10 more

Walks 13 inline items from wenshao's 16:46-17:28 reviews. 11 fixed, 1
deduped (lint-no-console flagged in both reviews), 1 reverted/push-back
(multi-part deny re-flags the same design-intent territory as R2 #4).

## Critical fixes

### sanitizeUrl: OAuth #fragment leak

`sanitizeUrl` cleared query params and Basic Auth userinfo, but
`u.toString()` preserved `u.hash`. OAuth 2.0 implicit grant puts
`access_token=...` directly in the fragment (e.g.,
`https://app/#access_token=gho_xxx&token_type=bearer`); some Azure
SAS variants similarly. Now `u.hash = ''` before serialize. For
rendered output (markdown / HTML / plaintext), the fragment is client-
state-only and dropping it removes the entire fragment-side leak surface.

### ESLint no-console on awaitingResync diagnostic

Project lint forbids bare `console.*`. Added
`eslint-disable-next-line no-console -- intentional diagnostic` per
wenshao's suggestion. Behavior unchanged.

### normalizeAuthDeviceFlowCancelled test coverage (still missing post-R4)

R4 added tests for one of the five device-flow normalizers; the
`cancelled` variant was still uncovered. Added happy + malformed-payload
tests.

## Behavior fixes

### Plaintext sanitizeTerminalText parity

`daemonBlockToPlainText` + `daemonToolPreviewToPlainText` previously
returned ANSI/bidi-control text verbatim, while markdown and HTML
paths sanitized via `sanitizeTerminalText`. A daemon emitting bidi
overrides survived clean to plaintext output — contradicting the
"copy-paste / logs" JSDoc intent. Now routes every text field through
`clean()` = `cap(sanitizeTerminalText(raw))`.

### blockquote helper applied to image_generation + subagent_delegation

R3 added the helper for thought/debug/error but missed two preview
markdown sites (`> ${text(preview.prompt)}` for image_generation,
`> ${text(preview.task)}` for subagent_delegation). Multi-line prompts
/ tasks now stay inside the blockquote.

### Default unrecognized-event branch: single debug block

Was emitting `status + debug` (2 blocks) per unknown event type. In
long sessions where the daemon adds new types an older SDK doesn't
recognize, this doubled block-consumption rate and accelerated
`maxBlocks` trimming of real content. Now emit a single `debug` block
that prefixes the event-type for adapters that want to pattern-match.

### writeIntent regex underscore-boundary aware

R4's `content` alias gate-check used `\b` word boundaries, but `\b`
doesn't match between `write` and `_` in `write_file` (both `\w`).
Fixed to `(?:^|[_-])verb(?:$|[_-])` which catches the canonical
`write_file` naming AND still rejects `prewrite_check`. Verb list
extended per wenshao's suggestion (`overwrite`/`modify`/`patch`/`generate`).

### useDaemonPendingPermissions over-subscription

Hook used `useDaemonTranscriptState()` which fires on every daemon
event (text deltas, tool updates, sidechannel). Switched to
`useDaemonTranscriptBlocks()` which only invalidates when the blocks
array reference changes — block-mutating dispatches only, thanks to
lazy COW. Same selector semantics, ~10x fewer renders in chat-heavy
sessions.

### Conformance suite: try/catch adapter

JSDoc promised "does not throw" but the loop wrapped adapter calls
without try/catch. Buggy adapters aborted the whole suite instead of
producing a structured `ConformanceFailure`. Now wrap; on throw,
capture the error message in `renderedExcerpt: "[adapter threw: ...]"`
and continue.

## Type / Quality fixes

### DaemonTranscriptState.blocks typed readonly

Runtime contract is frozen (lazy-COW poison defense), but the type
was mutable — consumers got runtime `TypeError` for in-place mutation
instead of compile errors. Now `readonly DaemonTranscriptBlock[]` so
mutation is caught at the type level.

### formatMissedRange exported / deduplicated

Helper was duplicated inline between transcript.ts (full phrasing)
and terminal.ts (terser phrasing). Exported from transcript.ts and
reused in terminal.ts to prevent future drift.

## Push-back (false-positive — see reply)

### classifySelectedPermissionOption multi-part deny (`selected:deny:access_violation`)

Re-flags the same `selected:X` design intent rejected in R2 #4. The
caller comment explicitly states a selected option resolves the prompt
even when the option id contains `deny`/`cancel`. The existing test
`cancelled-substring-permission` (payload `selected:abort`, expected
`completed`) codifies this. Daemon expresses true user-cancellation
via the `cancelled` PRIMARY token, not `selected:cancel`. Not
changing; reply directs to the same R2 #4 reasoning.

## Tests added (+10)

- normalizeAuthDeviceFlowCancelled happy + malformed
- sanitizeUrl OAuth fragment access_token rejected
- sanitizeUrl AWS/GCP/Azure SAS credential params stripped
- formatMissedRange no-gap / single-event / multi-event
- detectFileDiff content alias rejected for read-like tools
- detectFileDiff content alias accepted for write-like tools
- writeIntent word boundaries (prewrite_check NOT matched)
- conformance captures adapter throw
- unrecognized event → single debug block
- store.clearAwaitingResync clears latch

* fix(daemon-ui): wenshao R6 — recovery flow chicken-and-egg + pending pointer

Three Criticals from R6 review (4351217188) all pointing at real bugs
introduced by R4/R5 work — not false positives. Fixes plus regression
tests.

## Critical 1 — same-session reconnect never clears the latch

When the daemon emitted `state_resync_required`, the reducer set
`awaitingResync = true`. The webui provider dispatched
`assistant.done { reason: 'reconnected' }` after re-attaching SSE but
never called `store.clearAwaitingResync()`. Result: events flowed in
on the fresh stream but every one got dropped by the
`applyDaemonTranscriptEvent` passthrough guard. Transcript appeared
permanently frozen with no diagnostic clue (the `console.warn` fired
on each drop, but the user wouldn't necessarily check DevTools).

Fix: in `DaemonSessionProvider.tsx`, after dispatching the synthetic
`reconnected` `assistant.done`, check `awaitingResync` and clear it
BEFORE the new SSE event loop starts.

## Critical 2 — updateCurrentToolPointer breaks on undefined status

In `upsertToolBlock`, a new tool block is created with
`status: event.status ?? 'pending'`. But `updateCurrentToolPointer`
was called with raw `event.status` — when undefined, the function's
own `if (status === undefined) return;` guard short-circuited without
ever pointing at the new (visually-pending) block.

Result: `selectCurrentTool` returned `undefined` for daemon events
that omitted the explicit `status` field, while the block sat at
"pending" in the UI — invisible to the current-tool selector.

Fix: pass the EFFECTIVE status (`event.status ?? 'pending'`) so the
pointer logic mirrors the actual stored status.

## Critical 3 — clearAwaitingResync flow chicken-and-egg

The earlier (R4) JSDoc documented the recovery flow as: "re-subscribe
with `Last-Event-ID: 0`, then call clearAwaitingResync after replay
drains." But while the latch is true, EVERY non-passthrough event is
dropped at `applyDaemonTranscriptEvent`. So during the replay drain,
zero events made it into state, and clearing the latch afterward did
nothing — transcript permanently empty.

Correct flow: clear FIRST, then stream events. Updated JSDoc on both
`types.ts` interface and `store.ts` impl to document this clearly.

Added a regression test (`clearAwaitingResync AFTER dispatching events:
events ARE dropped`) that pins the correct flow in code.

## Regression tests (+3)

- `undefined status` creates pending block AND sets currentToolCallId
- clear-then-dispatch ✓ events flow
- dispatch-then-clear ✗ events dropped (correct flow documentation)

* fix(daemon-ui): wenshao R7 — escapeMarkdownText covers `<` + details URL sanitization

Two items from wenshao R7 (one inline Suggestion + one Verification-PASS
finding). Both gate-checked as real; fixed.

## escapeMarkdownText: add `<` to escape set

Markdown rendered through markdown-it with `html: true` would
previously pass through raw `<img onerror>` / `<script>` from
reviewer-untrusted metadata fields (tool title / toolKind / status /
permission label / preview labels). The HTML render path already
escapes via `defaultEscapeHtml`; this brings markdown to the same
safety baseline.

Note: `escapeMarkdownText` is only applied to metadata fields, NOT to
assistant/user/thought body text (those are intentionally markdown
content; escaping `<` there would mangle legitimate markdown).

## markdown tool details: sanitize URL credentials when sanitizeUrls:true

`daemonBlockToMarkdown`'s `case 'tool':` branch appended
`block.details` (serialized `rawInput` JSON) through `text()` which
only handled ANSI/bidi. When `rawInput.url` contained credentials
(Basic Auth in userinfo / OAuth in `#fragment` / signed-URL query
params), the preview path correctly sanitized via `sanitizeUrl`, but
the details dump leaked the raw URL.

HTML + plaintext branches exclude details entirely, so they didn't
leak. The asymmetry meant a consumer rendering markdown + relying on
the R5 fragment-leak protection would still leak via details.

Fix: added `sanitizeUrlsInText(text)` helper that regex-replaces every
`https?://` URL in a string with its `sanitizeUrl(url)` form. Applied
to `block.details` i…

First PR in the F5 release chain (PR 27 → 28 → 30a → 31) per the
2026-05-24 v0.16-alpha scope freeze in #4175 (text-only chat / coding
+ local-only deployment).

## SDK ergonomic micro-change (~50 LOC + 4 tests)

`DaemonClient` constructor falls back to `QWEN_SERVER_TOKEN` env
var when `opts.token` is absent — closes the asymmetry where the
daemon side already honors this var (--token CLI flag fallback,
already in main since PR 15) but the SDK forced clients to thread
it through every construction.

Properties:
- Browser-safe via `globalThis.process` indirection (the SDK is
  imported by @qwen-code/webui; literal process.env access would
  explode at module load on browser bundles)
- Whitespace stripped (matches daemon-side trim — handy for
  `export QWEN_SERVER_TOKEN=\"\$(cat token.txt)\"` where cat adds a
  trailing newline)
- Empty / whitespace-only treated as unset (a stale
  `export QWEN_SERVER_TOKEN=\"\"` won't accidentally send
  Authorization: Bearer with no token)
- Resolved at construction, not lazily per-request (later
  process.env mutations don't affect already-built clients)
- Explicit opts.token wins over env

Tests: 4 new in DaemonClient.test.ts `bearer auth` describe
covering env fallback / explicit-wins / empty-treated-unset /
whitespace-stripped. Plus a defensive snapshot/restore on the
existing 'omits Authorization when no token' test so an
inherited test-runner export of QWEN_SERVER_TOKEN doesn't turn
that assertion into a false positive.

This SDK fallback is the entire ergonomic replacement for PR 29's
SDK env/file fallback. PR 29's other features (auto-gen daemon
token, instance-path keying, stale cleanup) remain deferred to
v0.16.x — all are DX improvements over the boot-time security gate
already shipped in PR 15.

## v0.16-alpha docs (~120 LOC markdown)

- docs/users/qwen-serve.md: new "v0.16-alpha known limits" section
  enumerating product surface (text-only ✅, multimodal ❌),
  deployment surface (local launchers ✅, containerized ❌, multi-
  daemon ❌, BYO-token ✅), and hardening posture (boot security
  gate ✅, mutation gate ✅, MCP guardrails ✅, prompt absolute
  deadline ⏸️, rate limiting ⏸️, --max-body-size ⏸️). Adds an
  alpha banner at the top of the file.

- docs/developers/examples/daemon-client-quickstart.md:
  documents the SDK env fallback in both the Hello-daemon
  intro and the Authentication section, with the "export +
  no-token-arg" recommended path called out for local dev.

Verification: 125/125 DaemonClient.test.ts pass (121 existing +
4 new); 4/4 daemon-public-surface.test.ts pass (constructor
signature unchanged); tsc clean on packages/sdk-typescript;
eslint --max-warnings 0 clean on touched .ts files.

* fix(sdk): #4473 round 1 fold-in — 2 copilot doc threads adopted

T1 [copilot DaemonClient.ts:144 — stale line refs in readTokenFromEnv
  JSDoc]: removed `runQwenServe.ts:175` (token resolution actually
  lives at line 302-318 today, would drift again on next refactor)
  and `docs/users/qwen-serve.md:173`. Replaced with stable
  symbol/section references ("runQwenServe token-resolution path";
  "qwen-serve user guide CLI flags section").

T2 [copilot daemon-client-quickstart.md:33 — `~/.qwen/server-token`
  implies built-in path that doesn't exist]: PR 27 explicitly defers
  token auto-generation + file-store fallback (PR 29 deferred features).
  The example incorrectly suggested a standard file location.
  Replaced with two explicit user-managed alternatives:
  - `openssl rand -hex 32` one-shot
  - `cat ./my-token-file` user-managed file

Both threads were accurate suggestions caught at the right time
(zero behavior change; pure docstring/example accuracy).

Verification: 125/125 DaemonClient tests pass; tsc + eslint clean
on touched files.

* docs(deploy): local launch templates for v0.16-alpha (PR 30a) (#4483)

* docs(deploy): local launch templates for v0.16-alpha (PR 30a)

Third PR in the F5 release chain (PR 27 ✅ → PR 30a → 28 → 31) per
the 2026-05-24 v0.16-alpha scope freeze in #4175 (text-only +
local-only). Pure markdown, zero code.

New `docs/users/qwen-serve-deploy-local.md` (~160 LOC) with
copy-paste-ready templates for:
  - systemd user-level unit (Linux) + system-wide alternative
    callout for shared dev hosts
  - launchd LaunchAgent plist (macOS) with explicit "no ~ /
    \$HOME expansion" warning since that's a common foot-gun
  - tmux session for interactive supervision
  - nohup one-liner with "not recommended" caveats
  - curl smoke-check (/health + /capabilities) + token rotation
    walkthrough (covers all four launchers)

All templates inline `QWEN_SERVER_TOKEN=...` directly per the BYO-
token guide PR 27 added to qwen-serve.md. No auto-gen, no token-
store infrastructure — user generates via openssl rand -hex 32 and
pastes into the unit/plist. Each template carries an explicit
"DO NOT COMMIT this file with a real token" comment at the token
line.

Cross-references the SDK env fallback PR 27 added: one shell-level
`export QWEN_SERVER_TOKEN=\$(cat token-file)` covers both the
daemon-side flag fallback AND the SDK-side DaemonClient
construction fallback. Restart-and-crash semantics cross-link to
the existing Durability model section rather than duplicate.

Cross-links from qwen-serve.md "v0.16-alpha known limits" line 32
(forward reference "templates land in PR 30a" becomes a live
link) and "What's next" section (natural discovery hub at the
bottom). _meta.ts gets a sibling nav entry under qwen-serve.

Out of scope (deferred to v0.16.x or later): containerized
deployment (PR 30b), cross-host federation, auto-gen tokens,
native Windows service. WSL2 footnote covers Windows users for
free without committing to an unvalidated nssm wrapper.

Anchor integrity verified: links to #v016-alpha-known-limits /
#authentication / #durability-model all resolve to live sections
in qwen-serve.md.

Part of #4175.

* fix(docs): #4483 round 1 fold-in — 14 review threads adopted

All 14 unresolved threads (5 copilot + 9 wenshao) source-verified
and ADOPTED. Net effect: every code-block in the doc is now
copy-paste-runnable + the security / restart / log-location
posture matches what real local-deployment operators expect.

CRITICAL fixes:

T1 + T2 + T3 + T12 [copilot/wenshao — `--bind` flag does NOT exist]:
  Source-verified at packages/cli/src/commands/serve.ts:58 — the CLI
  flag is `--hostname` (with `--port`). All 4 templates (systemd /
  launchd / tmux / nohup) had `--bind 127.0.0.1` which would fail at
  startup with "unknown option". Replaced with `--hostname 127.0.0.1
  --port 4170` (explicit port for parity with launchd
  ProgramArguments). Defaults are 127.0.0.1:4170 already, but
  explicit-is-better here for copy-paste docs.

T6 [wenshao Critical — systemd missing loginctl enable-linger]:
  Without `loginctl enable-linger`, the user-level systemd instance
  shuts down at logout / does not start at boot. "Across reboots"
  was a stated goal of the doc. Added the linger command to the
  systemd manage block + a paragraph explaining why it's required
  for headless dev boxes.

T11 [wenshao — nohup missing workspace cd]:
  Daemon defaults to process.cwd() — running `nohup qwen serve` from
  ~ or /tmp silently binds the wrong workspace, causing every
  POST /session with the expected cwd to return 400 workspace_mismatch.
  Wrapped in `bash -c 'cd ~/your-project && qwen serve ...'` and added
  a paragraph explaining the silent foot-gun.

SUGGESTION fixes (security / correctness):

T7 [wenshao — systemd Environment= exposes token in unit file]:
  Replaced inline `Environment=QWEN_SERVER_TOKEN=...` with
  `EnvironmentFile=%h/.qwen-serve-token-env`. Unit file is typically
  644 (world-readable); EnvironmentFile keeps the token in the
  user's chmod 600 file. Added a setup step that wraps the existing
  token in KEY=value form for systemd to read.

T8 [wenshao — launchd /tmp logs have 3 problems]:
  Symlink-attack risk on shared workstations + truncate-on-load
  destroys diagnostic logs at exactly the wrong moment + macOS
  periodic-daily cleans /tmp after 3 days. Switched to
  `~/Library/Logs/qwen-serve/{out,err}.log`. Added the mkdir step
  in the manage block + a paragraph noting log truncation on
  unload→load.

T9 [wenshao — launchd KeepAlive=true respawns on clean SIGTERM]:
  Bare `<true/>` makes `kill <pid>` impossible (daemon respawns
  immediately). Switched to `<dict><key>SuccessfulExit</key><false/></dict>`
  to match systemd Restart=on-failure semantics. Added
  `ThrottleInterval=10` to mirror systemd RestartSec=5 and prevent
  restart storms on persistent failures.

T14 [wenshao — plist itself needs chmod 600]:
  The plist embeds the inline token. Files in ~/Library/LaunchAgents/
  default to 644. Added `chmod 600 ...plist` to the manage block.

T4 [copilot — /capabilities auth wording wrong]:
  Doc said /capabilities "always requires auth" — but it's only
  gated when a token is configured (or --require-auth is set). On
  a zero-config loopback boot neither route requires a header.
  Reworded "Verifying the daemon is up" section to call out both
  paths ("templates above all configure a token, so Authorization
  is needed in practice").

T5 [copilot — token rotation missing chmod 600]:
  Step 1 of token rotation now writes `~/.qwen-serve-token` AND
  `~/.qwen-serve-token-env` AND chmods both 600. Mirrors the
  initial generation block.

T10 [wenshao — restart-and-crash section self-contradictory]:
  Said sessions "re-attach via Last-Event-ID resume" then immediately
  "a restart drops sessions". Rewrote to clearly distinguish
  WITHIN-process disconnects (Last-Event-ID covers them, in-memory
  ring) from RESTART (drops everything; cross-restart durability
  not in v0.16-alpha). Also documented the systemd vs launchd
  KeepAlive semantics difference.

T13 [wenshao — bullet structure under "Generate a bearer token"]:
  The original bullet list framed `--token CLI flag` and the env
  var as if one consumed the other. Rewrote as a paragraph: "daemon
  reads token from either --token or QWEN_SERVER_TOKEN; SDK falls
  back to QWEN_SERVER_TOKEN; one shell-level export covers both".

Verification: `grep -c '\-\-bind ' docs/users/qwen-serve-deploy-local.md`
returns 0 (all bind→hostname); section structure intact (9 H2
sections, expected); 4 cross-link anchors to qwen-serve.md still
resolve (#authentication / #v016-alpha-known-limits /
#durability-model + the original out-of-scope list).

Net diff: +220/-160 (mostly net-additive — every fix added
context paragraphs explaining "why").

* fix(docs): #4483 round 2 fold-in — 2 wenshao threads adopted (T15 noise resolved)

T16 [wenshao — hardcoded /usr/local/bin/qwen breaks nvm/Volta/Apple Silicon Homebrew users]:
  Both systemd `ExecStart` and launchd `ProgramArguments` had
  hardcoded `/usr/local/bin/qwen` — only correct for Linuxbrew
  / Intel macOS Homebrew / manual global install. Most Node
  developers use nvm (~/.nvm/...), fnm, Volta, or Homebrew on
  Apple Silicon (/opt/homebrew/bin/qwen) and would hit
  "No such file or directory" on first `systemctl --user start`.

  Switched both templates to `/PATH/TO/qwen` placeholder + added a
  prominent callout block above each template listing the common
  locations (Linuxbrew, nvm, fnm, Volta on Linux; Apple Silicon
  Homebrew, Intel Homebrew, nvm, Volta on macOS) and explicitly
  pointing at `which qwen` as the discovery step. Inline
  comments at the ExecStart / ProgramArguments lines reinforce
  "systemd does NOT read $PATH" / "launchd does NOT read $PATH".

T17 [wenshao — shell-wide export leaks token to every subprocess]:
  Added a callout block immediately after the `export QWEN_SERVER_TOKEN=...`
  setup step warning against adding it to .bashrc/.zshrc on shared
  workstations. Profile-level export exposes the token to every
  child process (IDE subprocesses, browser debuggers, `npm`
  scripts from unrelated projects). Points users at the systemd
  EnvironmentFile= / launchd EnvironmentVariables mechanisms below
  for persistent setups since both scope the token to just the
  daemon process.

T15 [wenshao — empty "test" comment]:
  Resolved without code change. Comment body was just "test";
  appears to be an accidental post.

Verification: `/usr/local/bin/qwen` now only appears inside the
explanatory "common locations" prose blocks (NOT in the actual
templates, which use `/PATH/TO/qwen` placeholder); zero `--bind`
left in the file.

* feat(daemon+sdk): cross-client real-time sync completeness (#4484)

* feat(acp-bridge): cross-client real-time sync completeness (5 fixes)

Audit (cross-client sync, 2026-05-24) of the daemon's per-session
EventBus fan-out surfaced gaps where one client's actions did not
propagate to other SSE-subscribed clients on the same session. This
commit closes five of them — all bridge-layer fixes, no agent-side
changes — with regression tests covering the new sentinel frame.

## 1. user_message_chunk echo on the interactive prompt path

The agent's `Session#executePrompt` (Session.ts:556+) forwards the
prompt straight to the LLM without emitting `user_message_chunk` to
the session bus. The cron path (Session.ts:1402) and HistoryReplayer
(HistoryReplayer.ts:65) DO emit it; only the interactive path was the
outlier. Result: when client A sent a prompt, other clients on the
same session saw only the agent's reply, never the input — they had
to wait for a session reload to learn what A had asked.

Fix: `echoPromptToSessionBus` helper publishes one `user_message_chunk`
per content block of the incoming `PromptRequest`, stamped with the
envelope-level `originatorClientId` so SDK consumers with
`suppressOwnUserEcho: true` filter the echo on the originator's UI.
Multi-modal blocks (image / audio / resource) pass through verbatim
for future-compat with Core's multi-modal echo work.

`_meta.source: 'bridge-echo'` distinguishes bridge-synthesized echoes
from agent-emitted content. Used today only for diagnostic visibility;
becomes load-bearing once SDK-side dedup matures (deferred follow-up).

## 2. prompt_cancelled broadcast in cancelSession

`bridge.cancelSession` forwarded the ACP cancel notification to the
agent and resolved pending permissions, but did NOT publish any event
on the session bus. Other clients learned that A had cancelled only
by absence of further `agent_message_chunk` frames — heuristic and
late.

Fix: emit a `prompt_cancelled` envelope before the ACP forward so
peer clients see the cancel as a first-class event. Envelope-level
`originatorClientId` identifies the cancelling client (the one calling
`POST /cancel`). Permission-resolution events generated by the
subsequent `cancelPendingForSession` continue to omit an originator
(those are system-initiated wind-downs, not user-voted).

## 3. replay_complete sentinel in EventBus.subscribe

A consumer attaching via `Last-Event-ID: <n>` had no positive signal
when the replay loop drained — they had to heuristically time out the
catch-up spinner. The state-resync path already had a synthetic
`state_resync_required` frame; the success path lacked parity.

Fix: emit an id-less `replay_complete` synthetic frame at the end of
the replay loop (same pattern as `client_evicted` / `state_resync_required`
— no slot in the per-session monotonic sequence). Fires both when
replay actually delivered frames AND when there was nothing to replay
(empty ring), so the consumer always sees the transition from
"catching up" to "live". `data.replayedCount` is the actual count of
force-pushed frames (not derived from id arithmetic, which would
over-count when the state-resync path leaves a hole before the ring's
earliest id).

3 EventBus test cases updated to assert the sentinel frame ordering.

## 4. originatorClientId on session_metadata_updated envelope

`updateSessionMetadata` resolved the trusted client id for validation
(`resolveTrustedClientId(entry, context.clientId)`) but did not stamp
it on the broadcast envelope. UIs couldn't attribute the rename to a
specific client. Sibling events (`model_switched`, `approval_mode_changed`)
all stamp envelope-level `originatorClientId`; this brings the metadata
broadcast to parity.

## 5. originatorClientId on session_closed envelope

`session_closed` carried the closing client in `data.closedBy` only,
but every other event the bridge publishes uses the envelope-level
`originatorClientId` field. Added the envelope-level stamp (kept
`data.closedBy` for back-compat) so SDK consumers can read the
attribution from the same place across all event types.

## Out-of-scope (deferred to follow-up)

The cross-client sync audit also surfaced 3 items that require larger
design discussion:

- **In-session ACP `setModel` bus emit** — `Session.ts#setModel` calls
  `config.switchModel` directly without going through the bridge's
  publish path. Fixing this requires a new ACP sessionUpdate type
  (`current_model_update`, parallel to existing `current_mode_update`)
  or a side-channel callback from agent to bridge.
- **Workspace-wide broadcast of non-persisted approval-mode changes** —
  current behavior only broadcasts workspace-wide on `persist=true`;
  the design intent of the persist flag relative to multi-client
  visibility needs alignment.
- **Serialize `setSessionApprovalMode` through a queue** — analogous to
  `entry.modelChangeQueue` for `setSessionModel`. Race-condition fix.
- **Reconcile `permission_resolved.originatorClientId` semantics** —
  it currently carries the VOTER's clientId; `permission_request`
  carries the prompt originator. SDK consumers need to special-case
  the type. Either change to consistent semantics or add a separate
  `voterClientId` field.

These are tracked as follow-ups, not in this PR.

## Validation

| Bridge tests | 291/291 pass |
| eventBus tests | 105/105 pass (3 updated) |
| TypeScript | clean |

* test(acp-bridge): multi-client user_message_chunk echo coverage

Adds two integration tests for the cross-client sync fix:

- "echoes user_message_chunk to ALL session subscribers": two SSE
  subscribers (A + B) on the same session; client A sends a prompt;
  asserts BOTH receive the user_message_chunk with the originator
  stamp + `_meta.source: 'bridge-echo'`. This is the core multi-client
  property — a prompt from one client is visible to every subscriber,
  not just the originator.

- "echoes one user_message_chunk per content block (multi-modal)":
  a two-block prompt (text + resource_link) produces two echo frames
  in order.

Validates the bridge-layer echo end-to-end through the real
EventBus + subscribeEvents path, not just a unit of the helper.

* feat(daemon+sdk): address review — abort-path cancel, SDK recognition, hardening

Round-2 review of the cross-client sync work. Adds the sibling cancel
path, SDK-side recognition of the two new event types so consumers can
react instead of debug-dropping, plus hardening + test coverage flagged
in review.

## Bridge (acp-bridge)

- Abort-path cancel broadcast: the `sendPrompt` `onAbort` closure
  (originator SSE disconnect — the most common cancel trigger: tab
  close, network drop, laptop sleep) previously resolved permissions +
  forwarded ACP cancel WITHOUT publishing `prompt_cancelled`. Only the
  explicit `cancelSession` route emitted it. Extracted a shared
  `broadcastPromptCancelled` helper, called from both paths.
- echoPromptToSessionBus hardening: read `req.prompt` directly (no
  `unknown` cast so a future SDK type change is a compile error); cap
  echoed blocks at MAX_ECHO_CONTENT_BLOCKS (256) to bound fan-out + ring
  pressure; corrected the non-text comment (all ContentBlock variants
  are published verbatim, not "metadata-only").
- Documented prompt_cancelled's "cancel requested, not confirmed"
  semantic and the intentional unconditional broadcast.

## SDK (sdk-typescript)

The bridge now produces `prompt_cancelled` and `replay_complete`.
Without SDK recognition they fall through the normalizer default to
`debug` and the reducer drops them — consumers (VSCode ext, web UI,
React CLI) can't react. Added:
- both types to DAEMON_KNOWN_EVENT_TYPE_VALUES
- normalizer cases → typed UI events `prompt.cancelled` /
  `session.replay_complete`
- DaemonUiPromptCancelledEvent + DaemonUiReplayCompleteEvent types,
  union + barrel re-exports
- reducer: prompt.cancelled runs propagateCancellationToInFlightTools
  (clears peer-cancelled tool spinners, same idempotent path as
  assistant.done(cancelled)); session.replay_complete no-ops on blocks
- terminal projection cases for both
- guarded the existing awaitingResync console.warn with optional
  chaining so the no-console lint rule passes without referencing the
  member in the guard condition

## Tests

- bridge.test.ts: prompt_cancelled attribution; session_closed +
  session_metadata_updated envelope originatorClientId
- eventBus.test.ts: resync + replay paths assert the trailing
  replay_complete sentinel (replayedCount = actual delivered frames)
- daemonUi.test.ts: normalize prompt_cancelled / replay_complete (incl.
  empty-ring zero count); reducer cancellation propagation; replay no-op

## Validation

| | |
|---|---|
| acp-bridge tests | all pass |

## Deferred (docs/qwen-daemon/cross-client-sync-followups.md)

Ghost-echo-on-forward-failure; in-session ACP setModel bus emit;
approval-mode workspace broadcast + serialization; permission_resolved
voter semantics.

* test(acp-bridge): cover prompt_cancelled on the sendPrompt abort path

Review follow-up: the existing `prompt_cancelled` test only exercised
the explicit `cancelSession` route. The `onAbort` path (originator SSE
disconnect — tab close / network drop / laptop sleep, the most common
production cancel trigger) had no test asserting the broadcast reaches
peer subscribers. A future refactor dropping the `broadcastPromptCancelled`
call from `onAbort` would have passed silently and re-opened the
cross-client gap.

New test: hangs the prompt via a non-resolving `promptImpl`, attaches a
peer subscriber, aborts the originator's `sendPrompt` signal mid-flight,
and asserts the peer receives `prompt_cancelled` with the originator's
`clientId`. Releases the hung prompt before shutdown.

acp-bridge: 183/183 pass.

* feat(serve): add POST /session/:id/recap (#4504)

* feat(serve): add POST /session/:id/recap

Wraps generateSessionRecap (core/services/sessionRecap.ts) so daemon
clients can fetch a one-sentence "where did I leave off" summary
without driving the agent through a full prompt turn. Mirrors the
ext-method roundtrip used by /session/:id/approval-mode — bridge
forwards `qwen/control/session/recap` to the ACP child, which calls
the existing core helper against the per-session GeminiClient history.

- Route: non-strict mutation gate (parity with /prompt — costs tokens
  but mutates no state)
- Capability tag: `session_recap`
- SDK: `client.recapSession(sessionId, opts)` +
  `session.recap(opts)` convenience wrapper
- 60s bridge-side backstop timeout; client-disconnect aborts the
  HTTP wait (LLM call in the child still completes — recap is short)
- Recap is best-effort: short history / transient model failure
  surfaces as 200 with `recap: null`, not an error

Tests cover the route (200 happy path, 200 null recap, client-id
context, 404 on unknown session, malformed client-id, non-strict gate
posture), the bridge ext-method roundtrip (success, null recap,
SessionNotFoundError), the SDK client + session-client wrappers
(URL encoding, body, headers, signal propagation, 404 throw), and a
public-surface type lock for `DaemonSessionRecapResult`.

Closes part of #4175 (Top 5 ROI port #1 from the daemon coverage gap
inventory). Targets daemon_mode_b_main integration branch.

* docs(serve): reconcile recap cancellation docs with actual v1 behavior

Per chiga0's review on #4504 (option 1 — match docs to reality rather
than wire up cosmetic AbortController plumbing). The route, design doc,
and protocol reference all claimed "client disconnect aborts the
bridge-side wait" via `res.once('close')`, but the route has no such
listener and the bridge accepts no `AbortSignal`. The only ceilings
are the 60s `SESSION_RECAP_TIMEOUT_MS` backstop and the transport-
closed race against ACP channel death.

Wiring an HTTP-side AbortController in isolation would be cosmetic
because the ACP child handler also passes a never-aborting
`AbortController().signal` to the core helper (no cross-process abort
plumbing yet) — e2e cancel needs both layers. Recap is short (~1–5s,
`maxOutputTokens: 300`), so the absent cancellation is acceptable for
v1; a request-id-based cancel ext-method can land in a follow-up.

Also adds two known-limit bullets to the user guide per chiga0's other
minor notes: token-cost amplification on no-token loopback (no
per-route rate limit) and concurrent-recap safety (side-query reads
chat history via `GeminiClient.getChat().getHistory()` snapshot and
runs through a separate `BaseLlmClient`, never mutating the session's
`GeminiChat`).

* docs(serve): finish recap cancellation reconciliation in acpAgent ext-method

The previous commit (058bde70f) reconciled the cancellation narrative
in 3 doc files + the route comment in server.ts, but missed the inline
comment inside the ACP child's `SERVE_CONTROL_EXT_METHODS.sessionRecap`
handler. That comment still claimed "Client disconnect aborts the
bridge-side wait" — the exact false statement 058bde70f was meant to
remove from the codebase. Worse, the new server.ts comment from 058bde70f
points readers at this handler for corroboration ("This matches the ACP
child's `acpAgent.ts` handler ..."), so a reader following that crumb
would land on a comment saying the opposite.

Per @wenshao's `[Suggestion]` review on #4504, applying his suggested
replacement verbatim. Comment-only change; no behavior delta.

* docs(serve): finish recap cancellation reconciliation across bridge + SDK JSDocs

Third pass on the same task. wenshao caught one more spot in
`bridge.ts:330` (JSDoc for `SESSION_RECAP_TIMEOUT_MS` claimed "actual
cancellation on client disconnect is handled at the HTTP route layer"
— the exact opposite of what the route comment + protocol doc + design
doc + acpAgent comment all now say).

Pre-empting another round-trip by sweeping the rest of the codebase
and fixing the two remaining misleading SDK JSDocs in the same go:

- `DaemonClient.recapSession`: previously said "cancellation is via
  the optional signal" without qualifying that the signal aborts ONLY
  the local HTTP fetch. The daemon-side wait + the child-side LLM call
  both ignore it. Spelled out the layered reality: signal → fetch
  cancellation only; bridge → 60s backstop; ACP child → always runs to
  completion. Also corrected the "bypasses fetchTimeoutMs" claim — the
  raw `_fetch` simply doesn't go through that wrapper at all.
- `DaemonSessionClient.recap`: same clarification on the wrapper that
  delegates to `recapSession`.

Comment-only changes; no behavior delta.

* feat(daemon): add voterClientId to permission_resolved (A4)

Resolve the originator/voter ambiguity on permission_resolved without
breaking wire or SDK consumers (design PR #4511, A4):

- Wire: the mediator now emits data.voterClientId alongside the envelope
  originatorClientId on permission_resolved (same value, the resolving
  voter). Both are omitted together for no-voter resolutions (timer expiry,
  session-closed, loopback voter with no clientId). permission_already_
  resolved is unchanged (deliberately stamps neither).
- SDK: the normalizer exposes an optional voterClientId on the
  permission.resolved typed event, reading data.voterClientId and falling
  back to the envelope originatorClientId for daemons predating the field.
  originatorClientId stays available on the base (no rename, no break).

voterClientId is the canonical, unambiguous name; originatorClientId on
permission_resolved is kept as a deprecated alias (it means the voter here,
unlike the prompt originator on permission_request).

Tests: permissionMediator emits voterClientId (+ omits both with no voter);
normalizer surfaces voterClientId from data, falls back to originatorClientId,
omits it for no-voter. acp-bridge 297, sdk daemon-ui 186 pass.

Add the distinguishing case wenshao asked for: client A submits the prompt

the resolving vote (permission_resolved.voterClientId === B), and assert the
two differ — the disambiguation A4 exists to enable. The prior tests only

* feat(serve): --allow-origin <pattern> CORS allowlist (T2.4 #4514) (#4527)

* feat(serve): --allow-origin <pattern> CORS allowlist (T2.4 #4514)

Replace the unconditional `denyBrowserOriginCors` 403-wall with a
configurable allowlist when `--allow-origin <pattern>` is set. Each
pattern is either `*` (any origin, refuses to boot without a bearer
token) or a canonical URL origin validated by round-tripping through
`new URL(...).origin`. Matched origins receive standard CORS response
headers (`Access-Control-Allow-Origin: <echoed>`, `Vary: Origin`,
methods/headers/max-age) plus 204 short-circuit for OPTIONS preflight;
unmatched origins keep today's 403 envelope. `Origin: null` is always
rejected even under `*`. Conditional capability tag `allow_origin`
advertised when the flag is set so SDK/webui clients can pre-flight.

When `--allow-origin` is unset the install path is unchanged and
today's behavior is preserved bit-for-bit. Loopback self-origin hits
are unaffected — the existing demo-page Origin-strip shim runs first.

* docs(serve): align --allow-origin '*' wording with the actual boot gate

Copilot review on #4527 caught a doc/code mismatch: 5 spots said `*` is
"only safe with --require-auth" but the actual boot check refuses `*`
only when no bearer token is configured (any source: --token, env, or
--require-auth). Update the wording in all 5 spots to match the
implementation, and call out the secondary loopback-only caveat that
/health and /demo remain pre-auth on loopback unless --require-auth is
set — operators with a `*` allowlist on loopback should pair with
--require-auth for full hardening.

Tightening the code instead would break legitimate `*` + token + loopback
dev workflows that want /health to remain reachable for k8s/Compose
probes; the actual API surface is gated regardless of --require-auth.

* feat(daemon): in-session model switch reaches the bus (A1) (#4546)

* feat(daemon): in-session model switch reaches the bus (A1)

Implements A1 from the side-channel coordination design (#4511): a /model
slash command or plan-mode model switch now reaches attached clients, where
previously only the HTTP POST /session/:id/model path published model_switched.

Transport (per design v7): current_model_update is NOT an ACP SessionUpdate
variant (the type is the external @agentclientprotocol/sdk union — it has
current_mode_update but no model equivalent), so the agent emits the change
over the agent->bridge extNotification side-channel.

- Agent: Session.setModel emits a `qwen/notify/session/model-update`
  extNotification after switchModel resolves (success-only; captures the
  previous model id). Fire-and-forget — a failed notification never fails the
  switch.
- Bridge: BridgeClient.extNotification demuxes it to a model_switched bus
  event (currentModelId -> data.modelId), SUPPRESSED while the bridge is
  driving its own model roundtrip (entry.modelRoundtripInFlight, set around
  setSessionModel / applyModelServiceId) so the HTTP path — which also flows
  through Session.setModel — does not double-publish. Structured demux log
  records promoted / suppressed / dropped decisions.

Scope: this is the core A1 path + suppress + observability. The §2.2
post-roundtrip reconciliation and the timeout-race staleness check (for the
rarer concurrent-in-session / timed-out-then-late races documented in the
design) are a tracked follow-up.

Tests: agent emits the notification on success and not on failure; bridge
promotes it to model_switched when idle and suppresses it during a bridge
roundtrip. acp-bridge 302 pass.

* fix(daemon): address review on A1 in-session model update

- Update the extNotification JSDoc to list both recognized methods
  (mcp-budget-event + model-update).
- Drop previousModelId from the model-update notification — nothing consumed
  it end-to-end (dead data); model_switched is {sessionId, modelId}.
- setSessionModel: publish model_switched INSIDE the modelChangeQueue work
  callback (while modelRoundtripInFlight is still true), mirroring
  applyModelServiceId, so the agent notification can't slip through after the
  flag clears if transport ordering ever changes.

acp-bridge 302 pass; typecheck + lint clean.

* test(daemon): cover A1 demux defensive branches

Add the three branch tests wenshao flagged: malformed model-update params
(non-string ids → early return, no emit), unknown sessionId (dropped, not
buffered), and originatorClientId propagation (a model-update during an
in-flight prompt inherits activePromptOriginatorClientId on the promoted
model_switched).

## Critical #1 — 401/403 reconnect storm + transcript wipe

`DaemonSessionProvider`'s reconnect loop kept retrying `createOrAttach` on
401/403 even with `autoReconnect: true`. Each cycle:
  - hit the daemon with the same bad token → 401 again
  - cleared the session handle
  - the next successful attempt (if token magically recovered) would
    receive a different sessionId, triggering the `store.reset()` branch
    at line 143 and wiping the user's transcript
  - no terminal "auth failed" state surfaced to the user

Fix: split `TERMINAL_SESSION_HTTP_STATUSES` into `AUTH_FAILURE_HTTP_STATUSES`
(401, 403) and the rest (404, 410). On auth failure, return from the
reconnect loop unconditionally regardless of the `autoReconnect` flag —
these are credential failures, not transient. The user must update
credentials; daemon spam must stop.

`extractHttpStatus` helper factored out of `isTerminalSessionHttpError` to
share between the two predicates.

## Critical #2 — rawInput / rawOutput leaking secrets to UI

`normalizer.normalizeToolUpdate` forwarded `rawInput` / `rawOutput`
verbatim onto `DaemonUiToolUpdateEvent` → `DaemonToolTranscriptBlock`. The
`details` projection was redacted via `stringifyRedactedJson` /
`redactSensitiveFields`, but the underlying `rawInput` / `rawOutput`
fields were unredacted. Any UI component that read those fields directly
(ShellToolCall, WriteToolCall, JSON debug panels) leaked the raw values
to the DOM.

Example: `{ command: 'curl', apiKey: 'sk-prod-...' }` had `apiKey`
redacted in `details` but exposed verbatim on `rawInput`.

Fix: apply `redactSensitiveFields` to both `rawInput` and `rawOutput`
ONCE at the normalizer boundary, then reuse the redacted shape for the
`details` projection. Downstream is uniformly safe; no double traversal.

## Tests (49/49 pass)

- SDK `daemonUi.test.ts` (36 tests, +1) — new test `redacts sensitive
  fields in tool.update rawInput and rawOutput at normalizer boundary`
  verifies full-event string scan finds zero secret values + structural
  keys preserved with values `'[redacted]'`.
- WebUI `DaemonSessionProvider.test.tsx` (13 tests, +2) — new tests
  `breaks out of the reconnect loop on 401 / 403 auth failures even when
  autoReconnect is true` and `still reconnects on 404 / 410
  session-not-found errors when autoReconnect is true` lock in the
  asymmetry: auth failure → 1 attempt only; session-not-found → retries
  until success.

## Out of scope (declined / deferred — see PR review reply)

- CRIT #3 `withActionTimeout` test coverage gap → behavior correct,
  test-only follow-up (avoids PR bloat)
- Suggestions #4-7 → 4 nice-to-haves, deferred to keep PR focused on
  production-correctness fixes

* fix(serve): address qwen-latest review on merged #4291 (7 threads)

Seven post-merge findings from the qwen-latest review on #4291,
all real. Most are tightening fixes for issues introduced by the
earlier rounds of #4291 — the same security / DRY / observability
classes the original review surfaced, applied to surfaces that
weren't covered initially.

#1 (deviceFlow.ts:1179) — late-poll observer closure retained the
entire entry by reference (deviceCode/pkceVerifier BrandedSecrets +
cancelController) for the lifetime of the daemon if `provider.poll()`
never settled. Memory leak + indefinite secret retention. Destructure
the four fields the closure actually needs (deviceFlowId, providerId,
initiatorClientId, audit sink) so the entry is GC-eligible the
moment runPollTick returns.

#2 (server.ts) — `callerIsInitiator` was duplicated verbatim across
three locations: GET handler, toDeviceFlowStartResponseBody,
toDeviceFlowStateBody. The exact bug class #4291 was fixing was
"POST and GET diverged on the same redaction policy" — duplicating
the gate recreated the preconditions for divergence. Extracted to
shared `callerIsDeviceFlowInitiator(view, callerClientId)` helper
with the consolidated threat-model JSDoc. All three sites now call
the helper.

#3 (deviceFlow.ts:1110) — timeout callback constructed two separate
`DeviceFlowPollTimeoutError` instances (one for `signal.reason`, one
for the wrapper rejection). Each capture its own V8 stack trace,
and `signal.reason.stack` would diverge from the caught rejection's
stack — confusing for operators inspecting both. Build the sentinel
ONCE per timer fire and pass the same instance to both sites.

#4 (qwenDeviceFlowProvider.ts:273) — `Error.name` is a freely
assignable string property; a hostile fetch wrapper could set
`e.name = 'X\n[serve] FAKE LINE\x1b[31m'` to inject log lines or
ANSI sequences via the same vector we already closed for `oauthError`.
The non-OAuth catch path interpolated `${err.name}` raw. Apply the
same `sanitizeForStderr()` helper.

#5 (deviceFlow.ts:1551) — on the timeout path, `rawProviderError`
is undefined (deliberately, to skip the misleading
`provider.poll() threw (raw): ...` audit template), but that left
the audit hint field omitted entirely. Operators reading the
durable audit trail saw `errorKind: 'upstream_error'` with no signal
whether it was a hung IdP or a generic provider failure. Use
`result.hint` (which already carries the timeout-specific
`provider.poll() timed out after Nms; check IdP connectivity` text
built in the catch) so the audit matches the SSE event.

#6 (server.ts) — the `QWEN_SERVE_DEBUG` env-var check was inlined
in the GET route handler, duplicating the `isServeDebugMode()`
helper from `./debugMode.js` that workspaceAgents and
workspaceMemory already use. The inline copy also had a dead `?? ''`
fallback (the value is guaranteed truthy at that point per the
preceding check). Use the canonical helper.

#7 (deviceFlow.ts:1217) — late-rejection observer interpolated the
raw `lateErr.message` into the audit hint (truncated to 256 bytes,
but RFC 8628 `device_code` values fit comfortably in 256 bytes).
The provider's catch already uses the `name + length` redaction
pattern to prevent WAF-echoed `device_code`/PKCE leaks; the
registry layer was undoing that hardening because the same failure
settled late. Apply the same `name + length` pattern at the late-
rejection site.

Tests:
- Existing late-rejection test reseeded with a `device-code-secret-*`
  substring inside the long detail; hard-negative-asserts the seeded
  secret is absent from the audit + asserts the new
  `Error (message N bytes; raw suppressed)` shape.
- Existing poll-timeout test now also asserts: hint IS defined on
  the audit (not omitted), hint contains `'timed out after'` /
  `'check IdP connectivity'`, and `signal.reason instanceof
  DeviceFlowPollTimeoutError` (proves the single sentinel is
  shared between abort and reject).
- New `sanitizes control characters in attacker-controlled
  err.name` test in qwenDeviceFlowProvider.test.ts pins the round-4
  #4 fix with a hostile `e.name` containing `\n` + `\x1b[31m...`.

* fix(serve): address deepseek-v4-pro review on #4305 (4 threads)

Round-5 fold-in. Four findings from the deepseek-v4-pro review on
PR #4305 — all real, three are sister fixes for the same security
classes that #4305 already closed at adjacent surfaces.

#1 (deviceFlow.ts) — `pollTimedOut` race correctness. The flag was
set unconditionally inside the timer callback. If the provider
settled the wrapper at 29.9s, `finally` would call
`clearScheduled(pollTimer)` — but if the timer callback was already
queued for execution before the clear landed (a real possibility
in Node's event-loop ordering, even if not always observed in
practice), this branch could still run and incorrectly mark
`pollTimedOut`. Move the flag assignment to the catch block where
the settled cause is unambiguous via `instanceof
DeviceFlowPollTimeoutError`. New test pins the negative: provider
beats the timeout → no spurious `lost_late_poll_after_timeout`
audit even after ticking 2× the ceiling.

#2 (deviceFlow.ts) — late-rejection observer interpolated raw
`lateErr.name` into the audit hint without sanitization. Same
attacker-controlled vector closed at the provider layer for
`err.name` in round-4. Route through `sanitizeForStderr`.

#3 (deviceFlow.ts) — late-success observer interpolated
`latePollResult.kind` directly into the audit template. While the
typed shape is `'pending' | 'slow_down' | 'success' | 'error'`, a
non-conforming provider could return an arbitrary string. Same
log-injection vector. Route through `sanitizeForStderr`.

#4 (qwenDeviceFlowProvider.ts → deviceFlow.ts) —
`sanitizeForStderr` only stripped ASCII C0/C1 + DEL; bypass via
Unicode lookalikes:
  - U+2028/U+2029: LINE/PARAGRAPH SEPARATOR (newline-equivalent in
    most Unicode-aware terminals — most direct log-forging vector)
  - U+200B–U+200F: zero-width chars + LRM/RLM
  - U+202A–U+202E: bidirectional override controls
  - U+FEFF: BOM / ZWNBSP

A malicious IdP returning `slow_down
[serve] FAKE` in
`oauthError` would otherwise still forge log lines.

Architectural change: `sanitizeForStderr` was previously private to
`qwenDeviceFlowProvider.ts`. To address #2/#3, the registry layer
needs to call it too. Lifted into `deviceFlow.ts` (the foundation
module) and re-imported from the provider. Single source of truth;
the regex is now a module-level constant compiled once with explicit
`\uXXXX` escapes (via `String.raw` so the source is greppable, not
literal-Unicode-laden).

Tests:
- `does NOT attach late-poll observer when the provider beats the
  timeout` — N1 race regression
- `sanitizes hostile latePollResult.kind in late-observer audit` — N3
- `sanitizes hostile lateErr.name in late-rejection observer audit` — N2
- `sanitizes Unicode lookalike controls (U+2028 LINE SEPARATOR,
  bidi, ZWNBSP) in oauthError` — N4

* fix(serve): address gpt-5.5 + qwen-latest review on #4305 round-5 (5 threads)

Round-6 fold-in. Five findings split between maintainability,
security hardening, and a real defensive bug.

#1 (qwenDeviceFlowProvider.test.ts) — gpt-5.5: round-5 #4 test
embedded U+2028 / U+200E / U+FEFF as literal characters in source.
Invisible in GitHub diffs / most editors; the negative
`not.toContain('')` looked like an empty-string check. Rewrote
the payload + assertions to use named `\uXXXX`-bound constants.
Also added a companion test exercising U+2066–U+2069 (round-6 #5
below).

#2 (deviceFlow.ts) — qwen-latest: the late-poll observer's
`void tracked.then(...)` was missing a terminal `.catch(() => {})`.
A synchronous throw inside either handler (e.g., a misbehaving
`audit.record`: backpressure, malformed payload, sink out-of-disk)
would reject the derived promise unhandled. On Node 22's default
`--unhandled-rejections=throw`, that crashes the daemon. Added the
terminal `.catch(() => {})` matching the persist-tracker pattern.
New test injects a poison audit sink that throws specifically on
the `lost_late_poll_after_timeout` call; asserts `flushAsync()`
resolves cleanly.

#3 (deviceFlow.ts) — qwen-latest: the `case 'error'` audit-record
hint interpolated `rawProviderError` (raw `err.message`) without
`sanitizeForStderr`. Per ES2019+ `JSON.stringify` no longer escapes
U+2028/U+2029 — those would still forge log lines downstream
through file/stdout audit sinks. Apply the same sanitizer used on
every other provider-controlled audit path. New test pins a hostile
provider message containing U+2028 + ANSI escape and asserts
neither survives.

#4 (deviceFlow.ts) — qwen-latest: the round-5 #1 comment claimed
"`DeviceFlowPollTimeoutError` isn't exported as a public DeviceFlow
contract", but it IS `export class` (the test file constructs it
directly for fixtures). With `pollTimedOut = true` keyed solely on
`instanceof`, a future provider that imports + throws the class
would spoof the registry's "I caused the timeout" signal —
attaching a phantom late-poll observer.

Fix: introduce a runtime brand `_isRegistryTimeout: boolean` on the
class (default `false`) plus an internal-only
`makeRegistryPollTimeoutError(ms)` helper that sets the brand to
`true`. The brand is set ONLY at the registry's race-timer
construction site. Both gates updated:
  - `if (err instanceof X && err._isRegistryTimeout === true)` in
    the catch (for `pollTimedOut`)
  - `if (lateErr instanceof X && lateErr._isRegistryTimeout === true)`
    in the late-rejection self-filter

A provider-thrown brand-false instance now flows through the
generic provider-throw audit path — correctly auditing the misuse
rather than silently swallowing it. Repurposed the original "no
double-audit when registry's own DeviceFlowPollTimeoutError is
late-rejected" test (which was actually exercising the brand-false
path) into the inverted assertion: brand-false provider throw IS
audited as a real failure. Removed the orphaned old assertion; the
brand-true happy path is implicitly covered by the hanging-provider
test (which exercises the registry-built timeout end-to-end).

#5 (deviceFlow.ts) — qwen-latest: `sanitizeForStderr` regex covered
U+202A–U+202E (bidi embedding/override) but missed U+2066–U+2069
(LRI/RLI/FSI/PDI). These are the primary CVE-2021-42574
("Trojan Source") attack vectors — a hostile IdP swapping U+2066
for U+202D achieves the same visual reordering and would have
bypassed the round-5 filter entirely. Extended the regex range and
JSDoc; new test exercises U+2066/U+2068/U+2069 in `oauthError` and
asserts none survive while substantive ASCII parts remain.

PR #4312 review (Copilot): the round-6 #3 test (sanitizes

* fix(serve): post-merge P2 corrections from Codex review on #4282

Follow-up to PR #4282 (Wave 4 PR 17) addressing four P2 issues
flagged by Codex's `/review` after the squash-merge to main:

P2-1 — Read the workspace context filename for init
  `qwen serve` parent never goes through `loadCliConfig`, so the
  process-global `getCurrentGeminiMdFilename()` stays on the default
  `QWEN.md` even when the workspace configures
  `context.fileName: 'AGENTS.md'`. `runQwenServe` now snapshots the
  workspace's merged setting at boot and forwards via
  `BridgeOptions.contextFilename`, so init writes the same file the
  ACP child reads.

P2-2 — Restart MCP servers with a fresh disabledTools snapshot
  `Config.disabledTools` was frozen at construction time;
  `setWorkspaceToolEnabled` only updated settings.json. The
  documented "toggle + restart" workflow re-registered just-disabled
  tools because rediscovery still saw the bootstrap snapshot. Added
  `Config.setDisabledTools()` plus a re-read at the ACP restart
  handler so `discoverMcpToolsForServer` honors the latest set.

P2-3 — Match the SDK timeout to the daemon's restart budget
  Bridge waits up to 300s for stdio MCP discovery; SDK helper used
  the client-wide 30s default and aborted valid slow restarts.
  Added a per-call `timeoutMs` plumbed through `fetchWithTimeout`,
  defaulting `restartMcpServer` to 5 minutes.

P2-4 — Reject symlinked parent directories before init writes
  `lstat(target)` only checked the final component; a symlinked
  parent (e.g. `docs -> /tmp` with `context.fileName:
  'docs/QWEN.md'`) would let `writeFile` follow the link and create
  / truncate outside `boundWorkspace`. Added
  `canonicalizeExistingAncestor` (walks up through ENOENT to the
  deepest extant ancestor, then `realpath`s) and verifies the
  canonical parent stays within the canonical workspace.

5 new tests (4 bridge / 2 SDK):
- contextFilename snapshot honored
- parent-symlink escape rejected
- nested real subdir accepted
- restartMcpServer survives 1.2s response with 1s default timeout
- restartMcpServer honors a 50ms caller override

* fix(serve): fold-in 1 — address 16:32:44-round review on #4282

Follow-up addressing the 8 unresolved review threads opened on PR
shipping in this same #4297; addresses correctness gaps + missing
test coverage that would otherwise let regressions ride into main.

Behavior fix:
- broadcastWorkspaceEvent gains a `skipSessionId` parameter; when
  `setSessionApprovalMode` runs with `persist:true`, the broadcast
  skips the requesting session so it doesn't receive the same
  `approval_mode_changed` event twice (once via session-scoped
  publish + once via broadcast). The SDK reducer's
  `approvalModeChangedCount` now increments by 1, not 2, on the
  requesting client (peers still see 1 via the broadcast).
  Addresses #3260501134.

Observability + posture:
- broadcastWorkspaceEvent now mirrors PR 16's publishWorkspaceEvent
  member: per-entry success/failure accounting + an "ALL buses
  dropped" stderr elevation. The previous local helper silently
  swallowed every publish failure. Addresses #3260501126.
- WorkspaceInitPathEscapeError + WorkspaceInitSymlinkError typed
  classes for the two boundary guards in initWorkspace, mapped to
  HTTP 400 by sendBridgeError. Previous generic `Error` fell
  through to the 500 handler, telling operators "daemon broken"
  when the actual fix was workspace-config correction. Addresses
  #3260501161.

Public surface symmetry:
- Re-export McpServerNotFoundError, McpServerRestartFailedError,
  WorkspaceInitPathEscapeError, WorkspaceInitSymlinkError from the
  serve barrel. External embeds matching these via `instanceof`
  no longer need deep imports. Addresses #3260501163.

Test coverage:
- restartMcpServer bridge tests (5): success + event broadcast,
  soft-skip + refused event, McpServerNotFoundError translation,
  McpServerRestartFailedError translation, originator clientId
  stamping. Addresses #3260501141.
- sendBridgeError mapping tests (4): McpServerNotFoundError → 404,
  McpServerRestartFailedError → 502, WorkspaceInitPathEscapeError
  → 400, WorkspaceInitSymlinkError → 400. Addresses #3260501148.
- initWorkspace boundary guard tests (2 added): symlink-at-target
  rejected, contextFilename '../outside.md' rejected. Addresses
  #3260501157.
- TrustGateError tests assert the typed class via `.toThrow(TrustGateError)`,
  not just message text. Addresses #3260501165.

Also updates the existing fold-in 4 S2 broadcast test to reflect
the new no-duplicate semantics on the requesting session.

* fix(serve): fold-in 2 — copilot + wenshao review on #4297

Round-2 reviewer adoption on the same PR:

Critical fixes:
- `restartMcpServer` JSDoc documents `timeoutMs: 0` as "disable the
  timeout entirely", but the `> 0` guard in `fetchWithTimeout`
  rejected `0` and silently fell back to the 30s client default.
  Loosened the guard to `>= 0` so `0` flows through to the
  no-timeout branch via the existing truthiness check; NaN /
  negative inputs still coerce to the client default. Addresses
  duplicate reports from copilot (#3260577538) and wenshao
  (#3260661833).
- TS2322 in the slow-fetch test stub: `resolveResponse` was typed
  against `import('undici-types').Response` but assigned a
  `(v: Response) => void`. Re-typed against the global `Response`
  throughout. Caught only by tsc runs that include the test
  files. Addresses #3260663072.

Test fidelity:
- Slow-fetch stub now observes `init.signal` and rejects on abort,
  so a regression that drops the per-call `timeoutMs` override
  will reliably fail the test instead of resolving after the
  timer fired (false-negative coverage). Addresses #3260577600.
- New test pinning the `timeoutMs: 0` semantics: 1ms client
  default + a stub that resolves after 50ms. Without the `>= 0`
  fix, the call would abort at 1ms; with it, the explicit
  `0` disables the timer and the call completes.

Bug fixes:
- `runQwenServe.contextFilenameForInit` previously called
  `String(arr[0])` on the array branch, producing a literal
  `"[object Object]"` filename for hand-edited bad data. Now
  validates each element with `typeof === 'string'` and falls
  back to `undefined` (so the bridge uses its
  `getCurrentGeminiMdFilename()` default) when no string is
  found. Addresses #3260577641.

Documentation drift:
- `Config.getDisabledTools()` JSDoc rewritten to describe the
  mutable-via-`setDisabledTools()` semantics introduced by P2-2,
  and the "registration-time only / no retroactive unregister"
  contract that pairs with it. Old comment claimed the set was
  frozen at construction. Addresses #3260577677.

Observability:
- `acpAgent` MCP-restart `loadSettings` failure now surfaces a
  stderr line naming the server + the underlying error, instead
  of silently swallowing it. The documented "toggle + restart"
  workflow used to break with zero diagnostic when settings.json
  was corrupted or unreadable. Addresses #3260663303.

Code organization:
- Moved `canonicalizeExistingAncestor` after `describeStatKind` so
  the latter's JSDoc is no longer orphaned (TypeScript only
  associates the last `/** ... */` block before a declaration).
  Addresses #3260668618.

* fix(serve): fold-in 3 — read merged scope on MCP restart refresh

Critical bug from wenshao review (#3260725526) on PR #4297:
the P2-2 acpAgent re-read narrowed `Config.disabledTools` to
`SettingScope.Workspace` alone, dropping User / System scope
entries. The bootstrap Config received `merged.tools?.disabled`
(union of all scopes), so user-level / system-level disables
worked at boot — but the first `mcp restart` would replace the
in-memory set with the workspace scope alone, silently re-enabling
any tool that was disabled at a higher scope but absent from the
workspace file.

The asymmetry vs. the persist-write path is deliberate and
documented:
- Reads (here): merged — match the bootstrap Config snapshot,
  preserve user/system policy.
- Writes (`runQwenServe.persistDisabledTools`): workspace scope —
  don't bake higher-scope entries into the workspace file
  (per-#4282 fold-in 1 H2 fix).

Two paths look alike but answer different questions.

* fix(test): fold-in 4 — wire timeoutMs:0 stub to init.signal

Critical follow-up from wenshao (#3260810242) on PR #4297:
the new `timeoutMs: 0` regression test (added in fold-in 2)
inherited the same flaw it was meant to prevent — the slow-fetch
stub didn't observe `init.signal`, so a regression that ignored
the `0` override would fire the AbortController at the 1ms client
default but the stub would keep the promise pending. The 50ms
`resolveResponse` would win, the test would still pass, and the
documented "0 disables timeout" contract would be unprotected.

Mirrored the listener pattern already used by the two sibling
tests in fold-in 2 — `init.signal.addEventListener('abort', () =>
reject(...))`. Now a regression that re-rejects `0` triggers the
abort, the stub rejects, the test fails.

8/8 restartMcpServer SDK tests pass; SDK typecheck clean.

* fix(serve): fold-in 5 — TOCTOU + setDisabledTools coverage

Two new critical reviews from wenshao on PR #4297:

C1 — TOCTOU between lstat and writeFile (#3260836305):
The `lstat(target)` symlink check and the subsequent `writeFile`
were two separate syscalls, leaving a race window where a local
attacker with workspace write access could substitute a symlink
between them. With `force: true`, `writeFile` would follow the
link and truncate an external target.

The `action === 'created'` path now uses `fs.open(target, 'wx')`
(O_WRONLY|O_CREAT|O_EXCL), which atomically refuses any
pre-existing inode (regular file, dir, OR symlink) at the target
path. EEXIST after the absence check most plausibly means a
race-created symlink, so we throw `WorkspaceInitSymlinkError(kind:
'target')` — same typed class the route maps to 400.

The `force: true` overwrite path retains the existing TOCTOU as a
documented limitation; closing it requires `O_NOFOLLOW`-aware open
which the post-PR18 `WorkspaceFileSystem` migration will provide.

C2 — P2-2 zero test coverage (#3260836302):
The `setDisabledTools` runtime sync was the only Wave-4 P2 fix
without a dedicated test. Added 5 Config-level tests:
- Initializes from `disabledTools` ConfigParameters
- Defaults to empty set when omitted
- `setDisabledTools` replaces the live snapshot
- Defensive copy: caller-set mutations don't leak into the live snapshot
- Accepts an empty set (clears live snapshot)

Plus a TOCTOU regression test in httpAcpBridge.test.ts that
spies fs.lstat / fs.readFile to simulate the race window:
pre-creates a symlink, makes lstat lie about it, asserts the
'wx' open catches the racing inode and throws the typed
`WorkspaceInitSymlinkError(kind: 'target')`.

1622/1622 unit tests pass; typecheck clean across cli /
sdk-typescript / core.

* fix(serve): fold-in 6 — count actual skips in broadcast alarm

DeepSeek review on #4297 (#3261079572):
`broadcastWorkspaceEvent` unconditionally subtracted 1 from the
`eligible` recipient count whenever `skipSessionId` was set, even
when the id matched zero live sessions (caller mistake, stale id,
or the matching session was just torn down between resolution and
broadcast). In a single-session workspace that's the difference
between `eligible = 0` (alarm suppressed) and `eligible = 1`
(alarm fires when the publish failed) — silently losing the
all-dropped breadcrumb the telemetry was meant to surface.

Today's call sites pass real session ids so the bug doesn't
manifest in practice, but the defensive shape is small: track
`skippedCount` inside the loop and subtract that, so the alarm
condition is self-consistent regardless of how the caller mis-uses
the param.

162/162 bridge tests pass; CLI typecheck clean.

* fix(serve): fold-in 7 — close overwrite TOCTOU, harden boot + diagnostics

Round-7 review on PR #4297. Three critical fixes + one suggestion
test, plus a regression test for the overwrite TOCTOU close.

C1 — force:true overwrite TOCTOU (#3262615446):
The fold-in 5 fix only closed the `'created'` action via 'wx';
the `'overwrote'` branch still used plain `fs.writeFile`, so a
local writer could swap the verified regular file to a symlink
between the lstat/readFile checks and the write and have the
forced overwrite truncate an external target. Switched to
`fs.open(target, O_WRONLY | O_TRUNC | O_NOFOLLOW)` — `O_NOFOLLOW`
makes open() fail with ELOOP on a symlink at the final component
even under race. ELOOP / ENOENT (race-deleted) translate to
`WorkspaceInitSymlinkError(kind: 'target')` so the route still
maps to a structured 400 instead of a generic 500.

C2 — settings.json corrupt blocks daemon boot (#3262625091):
`loadSettings(boundWorkspace)` at boot had no try/catch — a
corrupted, malformed, or temporarily unreadable settings file
threw synchronously and prevented daemon startup. Pre-PR this
never happened because settings were read lazily inside request
handlers. Wrapped in try/catch with stderr fallback so the daemon
keeps booting (with the bridge's default context filename) when
the file is broken.

C3 — malformed `tools.disabled` clears policy silently (#3262625101):
When `merged.tools?.disabled` is present but not an array
(boolean / string / object from a hand-edited settings.json), the
ternary `Array.isArray(...) ? ... : []` substituted an empty list
without firing the surrounding catch block. After an MCP restart
every disabled tool would silently re-register. Added an explicit
`!Array.isArray && !== undefined` check that stderr-logs the
malformed type before clearing — operators see the
misconfiguration instead of a stealth re-enable.

S1 — contextFilename extraction tested (#3262690842):
Lifted the inline `firstStringInArray` + branching into an
exported `extractContextFilename(value: unknown)` helper and
added `runQwenServe.test.ts` with 5 tests covering the four
branches the suggestion called out: non-empty string, array with
strings, array with no strings, non-string non-array.

Plus a TOCTOU regression test for the overwrite path that
verifies `O_NOFOLLOW` returns `WorkspaceInitSymlinkError(kind:
'target')` when the file is race-substituted with a symlink
behind the lstat/readFile mocks.

S2 (acpAgent restart-handler integration test #3262690845) is
deferred — Config-level coverage of `setDisabledTools` already
locks the load-bearing surface (5 tests in fold-in 5), and
adding a full acpAgent integration test requires heavy ext-method
plumbing. The new C3 stderr diagnostic plus existing tests give
us the regression signal we need without that scaffolding.

1627/1627 unit tests pass; typecheck clean across cli /
sdk-typescript / core / acp-bridge.

* fix(serve): fold-in 8 — split ELOOP / ENOENT diagnostic in overwrite path

qwen-latest review on PR #4297 (#3262861754):
The fold-in 7 ELOOP/ENOENT branch shared one error message that
said "swapped to a symlink." That's accurate for ELOOP (genuine
O_NOFOLLOW rejection — likely an attack race) but misleading for
ENOENT in the overwrite path: there `readFile` just succeeded
proving the file existed, so ENOENT means the file was DELETED
between the content check and the open — a benign race with a
concurrent writer (git checkout, editor save, lockfile rename),
NOT a symlink swap. An operator seeing the symlink language for
a benign delete would `ls -la`, see no symlink, and waste time
hunting an attack that didn't happen.

Split into two messages:
- ELOOP: "swapped to a symlink between the content check and the
  overwrite — refusing to follow it"
- ENOENT: "deleted between the content check and the overwrite
  (likely a concurrent writer) — refusing to recreate blindly"

Both still surface as `WorkspaceInitSymlinkError(kind: 'target')`
so the route maps to a structured 400; the class doubles as the
workspace-init race-condition bucket with kind='target' meaning
"target inode misbehaved at write time" generally.

Updated the existing fold-in 7 TOCTOU test to assert the ELOOP
message specifically, and added a new ENOENT race-delete test
that mocks lstat/readFile to land on the overwrote action against
a non-existent path — verifies the message says "deleted" and
NOT "swapped to a symlink."

170/170 bridge tests pass; CLI typecheck clean.

* fix(serve): fold-in 9 — route MCP restart through registry cleanup wrapper

gpt-5.5 critical review on PR #4297 (#3263088414):

The fold-in 5 P2-2 fix refreshed `Config.disabledTools` from merged
settings, but then called `manager.discoverMcpToolsForServer()`
directly — bypassing the `ToolRegistry.discoverToolsForServer`
wrapper that PURGES the server's existing `DiscoveredMCPTool`
entries (and `revealedDeferred` markers) plus its prompts before
rediscovery. Without the cleanup, `registerTool` only consulted
the refreshed `disabledTools` set for NEWLY-discovered tools —
entries already in the registry from the prior MCP boot kept
serving requests. Net effect: toggle-disable-then-restart
silently left the disabled tool live, breaking the documented
"toggle + restart" workflow that P2-2 was meant to fix.

Routed through `toolRegistry.discoverToolsForServer(serverName)`
which:
1. Removes existing `DiscoveredMCPTool` entries for this server
2. Drops their `revealedDeferred` reveal state
3. Removes the server's prompts via `removePromptsByServer`
4. THEN delegates to `manager.discoverMcpToolsForServer` for the
   actual reconnect + rediscover

The pre-discovery budget / in-flight checks still go through the
`manager` reference (which is the same object the registry
wrapper would forward to) — so soft-skip semantics for
`budget_would_exceed`, `in_flight`, `disabled` are preserved.

CLI typecheck clean; 403/403 server + bridge tests pass.

* fix(serve): fold-in 10 — qwen-latest 05:45-round review on #4297

5 review threads from qwen-latest's late round on PR #4297 (now closed
in favor of #4313 against `daemon_mode_b_main`). 1 critical + 4
suggestions, all adopted.

C1 — extractContextFilename / getCurrentGeminiMdFilename divergence
(#3263954685): with `context.fileName: ['  ', 'AGENTS.md']`, the
daemon parent's `extractContextFilename` (which skips empty entries)
wrote `AGENTS.md`, but the ACP child's `getCurrentGeminiMdFilename`
(which returned `arr[0]` unconditionally) read `''`. The init'd file
was orphaned. Aligned `getCurrentGeminiMdFilename` to skip empty
entries with the same semantics, falling back to
`DEFAULT_CONTEXT_FILENAME` when all entries are empty.

S2 — WorkspaceInitSymlinkError reused for non-symlink races
(#3263954690): the EEXIST race-create and ENOENT race-delete cases
were surfacing as `code: 'workspace_init_symlink'`, misleading
operators into hunting symlink attacks for benign concurrent-
modification windows. Split into a sibling `WorkspaceInitRaceError`
class (`kind: 'eexist' | 'enoent'`, HTTP code
`workspace_init_race`). The genuine symlink class stays for ELOOP,
lstat-detected target symlinks, and parent-realpath escapes.

S3 — fsConstants.O_NOFOLLOW defensive `?? 0` (#3263954697): matches
the existing codebase convention in
`core/src/utils/{sessionStorageUtils,gitDiff}.ts` and
`cli/src/ui/utils/customBanner.ts`. Functionally a no-op (JS
bitwise coerces undefined to 0) but consistent.

S5 — Parent-directory TOCTOU still open (#3263954707): O_NOFOLLOW
only protects the final path component; a local writer could swap
a real parent dir for a symlink between
`canonicalizeExistingAncestor` and `fs.open`. Added
`verifyParentWithinWorkspace` post-open helper that re-realpaths
`path.dirname(target)` and refuses with
`WorkspaceInitSymlinkError(kind: 'parent')` if the parent moved.
On the create path (where we just opened with `'wx'`), the failure
also unlinks the file we just made best-effort. Residual race
window narrowed from "between pre-check and open" to "between
post-open realpath and writeFile" — sub-millisecond, documented as
accepted Stage-1 trust posture.

S4 — broadcastWorkspaceEvent vs publishWorkspaceEvent stale comment
(#3263954688): the "now removed" comment was inaccurate (5 call
sites still use the closure). Replaced with an accurate
description of why both coexist (factory closure can't `this`-call
proxy member; closure also takes `skipSessionId` for persisted
approval-mode mirror) and a TODO marker for future helper extraction.

Two existing tests updated to assert the new `WorkspaceInitRaceError`
class for EEXIST / ENOENT scenarios (the symlink-class assertions
are preserved for ELOOP / lstat / parent cases).

* refactor(acp-bridge): lift defaultSpawnChannelFactory to acp-bridge/spawnChannel (#4175 F1 step 1)

First mechanical lift of #4175 F1 (acp-bridge package self-sufficiency).
Moves the production spawn factory + its `killChild` helper +
`SCRUBBED_CHILD_ENV_KEYS` denylist + `KILL_HARD_DEADLINE_MS` constant
from `cli/src/serve/httpAcpBridge.ts` (~283 lines) to
`@qwen-code/acp-bridge/spawnChannel`. This unblocks
`channels/base/AcpBridge.ts` and `vscode-ide-companion`'s
acpConnection from each reimplementing the child lifecycle — they can
now consume the same primitive.

Backward compatible: `cli/src/serve/httpAcpBridge.ts` imports the
lifted factory and re-exports it, so existing references in
`cli/src/serve/index.ts:90` and the factory's own internal usage
(`opts.channelFactory ?? defaultSpawnChannelFactory`) keep resolving.
Bridge tests that mock `defaultSpawnChannelFactory` via
`BridgeOptions.channelFactory` are unaffected.

Side cleanups: drops `spawn` / `ChildProcess` / `Readable` / `Writable`
/ `ndJsonStream` / `MissingCliEntryError` imports from
httpAcpBridge.ts (all only used by the lifted spawn factory).

* refactor(acp-bridge): lift BridgeClient + permission types to acp-bridge/bridgeClient (#4175 F1 step 2)

Second mechanical lift of #4175 F1 (acp-bridge package self-sufficiency).
Moves `BridgeClient` class (~700 LOC) + `PendingPermission` interface +
`PermissionResolutionRecord` interface + `MAX_RESOLVED_PERMISSION_RECORDS`
constant + early-event capacity constants + `describeStatKind` and
`sliceLineRange` helpers from `cli/src/serve/httpAcpBridge.ts` to
`@qwen-code/acp-bridge/bridgeClient`.

Design choice for SessionEntry boundary: introduce a minimal
`BridgeClientSessionEntry` interface in bridgeClient.ts with only the
four fields BridgeClient actually reads from the factory's richer
`SessionEntry` (`sessionId`, `events`, `pendingPermissionIds`,
`activePromptOriginatorClientId`). The factory's `SessionEntry`
structurally satisfies it — TypeScript's structural typing enforces
the match at the `resolveEntry` callback signature, so no explicit
conversion is required and the bridge package stays free of daemon-host
session-bookkeeping types.

Cross-package writeStderrLine handling: inline the 3-line helper in
bridgeClient.ts (mirrors the spawnChannel.ts pattern from F1 step 1)
so acp-bridge has no reverse dependency on `cli/src/utils/stdioHelpers`.

httpAcpBridge.ts shrinks from 4406 LOC to 3647 LOC (-759 lines).
Removed ACP SDK imports that only BridgeClient consumed: `Client`,
`RequestPermissionRequest`, `WriteTextFileRequest`,
`WriteTextFileResponse`, `ReadTextFileRequest`, `ReadTextFileResponse`,
`SessionNotification`. Kept the ones the factory still uses
(`CancelNotification`, `PromptRequest`, `RequestPermissionResponse`,
`SetSessionModelRequest`, `SetSessionModelResponse`).

Backward compatible: httpAcpBridge.ts re-exports `BridgeClient`,
`BridgeClientSessionEntry`, `PendingPermission`,
`PermissionResolutionRecord`, and `MAX_RESOLVED_PERMISSION_RECORDS` so
the `ChannelInfo.client: BridgeClient` field declaration below + any

* refactor(acp-bridge): lift createHttpAcpBridge factory to acp-bridge/bridge (#4175 F1 step 3)

Third + final mechanical lift of #4175 F1 (acp-bridge package
self-sufficiency). Moves the `createHttpAcpBridge` factory closure
(~3000 LOC) + `ChannelInfo` + `SessionEntry` interfaces + factory-only
helpers (`canonicalizeExistingAncestor`, `verifyParentWithinWorkspace`,
`withTimeout`, `isServeDebugLoggingEnabled`, `writeServeDebugLine`,
`hasControlCharacter`) + factory constants (`DEFAULT_INIT_TIMEOUT_MS`,
`MCP_RESTART_TIMEOUT_MS`, `DEFAULT_MAX_SESSIONS`, `MAX_EVENT_RING_SIZE`,
`DEFAULT_PERMISSION_TIMEOUT_MS`, `DEFAULT_MAX_PENDING_PER_SESSION`,
`MAX_DISPLAY_NAME_LENGTH`) from `cli/src/serve/httpAcpBridge.ts` to
`@qwen-code/acp-bridge/bridge`.

`cli/src/serve/httpAcpBridge.ts` shrinks from 3647 LOC to 97 LOC — a
pure re-export shim that preserves every existing relative import
path (`./httpAcpBridge.js`) so `server.ts`, `runQwenServe.ts`,
`workspaceAgents.ts`, `workspaceMemory.ts`, `index.ts`, plus the bridge
test suite, keep resolving without any call-site changes.

The new `bridge.ts` reuses what was already in acp-bridge (errors,
types, options, status helpers, channel types, event bus, workspace
paths) via local relative imports — no reverse dependency on `cli`.
`writeStderrLine` is inlined at the top of `bridge.ts` (same pattern as
`spawnChannel.ts` + `bridgeClient.ts` from F1 steps 1-2) so the
package self-contained promise holds.

Cumulative F1 impact across the 3 mechanical lift steps:
- httpAcpBridge.ts: 4682 LOC → 97 LOC (-4585 lines; the original file
  was 98% bridge core, 2% backward-compat re-exports)
- 3 new files in acp-bridge: spawnChannel.ts (~270 LOC), bridgeClient.ts
  (~745 LOC), bridge.ts (~3515 LOC)
- All daemon-host concerns (env snapshot, daemon preflight cells)
  remain in `cli/src/serve/daemonStatusProvider.ts` and reach the
  bridge through the `BridgeOptions.statusProvider` seam frozen by
  PR 22b/2.

- 174/174 cli httpAcpBridge tests pass
- 44/44 acp-bridge tests pass
- typecheck clean across acp-bridge + cli

`packages/cli/src/serve/httpAcpBridge.test.ts` (~6600 LOC) is
intentionally NOT moved in this commit — it currently imports
`createHttpAcpBridge` / `defaultSpawnChannelFactory` / `BridgeClient`
via the cli shim and keeps passing without changes. Moving it to
`acp-bridge/src/bridge.test.ts` is a follow-up worth tracking
separately so the production-code lift can land + be reviewed cleanly.

The `BridgeFileSystem` injection seam (originally bundled into F1 as
the 22b' scope) is also deferred to a follow-up so the mechanical lift
stays mechanical — design + implementation of the fs injection is its
own discussion.

* feat(acp-bridge): add BridgeFileSystem injection seam (#4175 F1 step 5, 22b' scope)

Adds the `BridgeFileSystem` injection seam originally scoped as #4175
22b'. When a `BridgeFileSystem` is wired through
`BridgeOptions.fileSystem`, `BridgeClient.readTextFile` and
`BridgeClient.writeTextFile` delegate to it instead of running their
inline `fs.realpath` / `fs.writeFile` / `fs.readFile` proxy.

This unblocks production `qwen serve` plumbing PR 18's
`WorkspaceFileSystem` (TOCTOU guards, symlink-substitution checks,
trust gate, `.gitignore`, audit hooks) into the ACP fs methods —
closing the `ws.ts:613` follow-up thread that has been tracked since
PR 18 landed. The serve-side adapter that wraps `WorkspaceFileSystem`
+ the `runQwenServe` wiring are intentionally split into the
immediate-follow-up so this PR stays focused on the seam design.

Backward compatible: `fileSystem` is optional on `BridgeOptions`.
Tests, Mode A in-process consumers, channels (`packages/channels/base/
AcpBridge.ts`), and the VSCode IDE companion all keep working
unchanged — they omit the field and `BridgeClient` falls through to
the inline proxy that has been the Stage 1 default since #3889.

API:
- `BridgeFileSystem.readText(params: ReadTextFileRequest):
  Promise<ReadTextFileResponse>`
- `BridgeFileSystem.writeText(params: WriteTextFileRequest):
  Promise<WriteTextFileResponse>`

The interface mirrors ACP SDK request/response types directly so the
adapter does the minimum amount of translation (`{ path, content }`
↔ `WorkspaceFileSystem`'s `ResolvedPath` brand types + options bag).

Self-review fold-in: post-F1 the package README still said "PR 22a"
and listed `BridgeClient` / `createHttpAcpBridge` /
`defaultSpawnChannelFactory` under "What's not here yet" — both
contradicted by this PR. Updated:

- README lift-history table now shows PR 22a / 22b/1 / 22b/2 as
  merged and F1 (this PR) as the slice that closes the bridge core
  + adds `BridgeFileSystem`. F3 PR 24 row aligned to the
  feature-cohesive plan.
- "What's here today" now documents `spawnChannel`, `bridgeClient`,
  `bridge`, `bridgeFileSystem` modules.
- "What's not here yet" section removed (its 2 bullets are both
  resolved by F1).
- Subpath import list updated to enumerate all 14 subpaths.
- Backward-compat section updated to call out the 97-line shim and

Source-comment line-number drift:
- `channel.ts:12` no longer claims `defaultSpawnChannelFactory` is

- `permission.ts:33` + `permission.ts:45` no longer reference
  `httpAcpBridge.ts:1096-1106` / `httpAcpBridge.ts:1003` (file is

  equivalent locations inside the lifted `bridgeClient.ts`.
- `permission.ts:7` no longer says first-responder still lives in
  `cli/src/serve/httpAcpBridge.ts` — points at the bridgeClient.ts
  location.

* docs(acp-bridge): adopt 3 Copilot review comments on F1 doc accuracy

Folds in 3 of 4 Copilot inline comments from #4319 review:

1. `bridgeClient.ts` writeTextFile preserveMode comment said "fall
   through to umask defaults" for new files, but the code passes
   `mode: preserveMode?.mode ?? 0o600` to `fs.writeFile`. Updated the
   "BkwQW" comment + the inner catch-block comment to clarify that
   new files actually get the `0o600` default applied at writeFile
   time (NOT umask defaults — the explicit `mode` arg bypasses umask
   for atomicity per the `Blehd` comment block).

2. `bridgeFileSystem.ts` JSDoc referenced
   `cli/src/serve/bridgeFileSystemAdapter.ts` as if the file exists,
   but it's deferred to the immediate F1 follow-up PR. Reworded as
   "the immediate follow-up PR will land a serve-side adapter" so
   reviewers don't grep for a non-existent file.

3. `bridgeOptions.ts` `fileSystem` field JSDoc had the same wording
   issue ("Production `qwen serve` wires this to..."). Same fix — now
   says "The immediate F1 follow-up will land a serve-side adapter"
   so the deferred state is obvious.

Declined from this review round:

- Copilot inline #1 (`spawnChannel.ts:155` stderr forwarder drops
  empty lines): pre-existing behavior since #3889. F1 lifted verbatim
  — not a regression introduced here. Out of scope for a lift PR.
- github-actions bot summary: most items are pre-existing notes
  (TOCTOU residual race, SCRUBBED_CHILD_ENV_KEYS allowlist concern,
  sliceLineRange benchmark threshold) on code the F1 lift moved
  verbatim. One ("httpAcpBridge.ts still has ~3700 LOC") is a false
  positive — the file is 97 LOC after F1. Others are cosmetic
  refactors (extract FIXME to tracking issue, ARCHITECTURE_DECISIONS
  doc system, deprecation timeline) that aren't worth churning the

* docs(acp-bridge): tighten BridgeFileSystem contract + re-export type from shim

Self-review + code-reviewer agent fold-in, two changes:

1. `cli/src/serve/httpAcpBridge.ts` shim now re-exports
   `BridgeFileSystem` from `@qwen-code/acp-bridge/bridgeFileSystem`
   so the immediate F1 follow-up adapter (in `cli/src/serve/`)
   can import it via the established `./httpAcpBridge.js` path
   like every other daemon-side bridge import does. Without this
   the adapter would need to deep-import from acp-bridge while
   every other serve file goes through the shim — inconsistent.

2. `BridgeFileSystem.readText` + `writeText` JSDoc now spells out
   the two defensive gates the inline proxy carried (non-regular-
   file rejection + 100 MiB buffered-size cap for reads;
   write-then-rename atomicity + dangling-symlink walk-through +
   mode preservation + `0o600` new-file default for writes). When
   a `BridgeFileSystem` is injected, the inline path is FULLY
   bypassed — without the contract spelled out, a future adapter
   author could silently drop the `/dev/zero` / 500 MB log RSS
   defenses the inline path established.

Note on F1 CI: this PR targets `daemon_mode_b_main` but the
`.github/workflows/ci.yml` `pull_request` trigger is scoped to
`branches: main / release/**`, so the main CI workflow (Lint /
Test on Linux/macOS/Windows / CodeQL) does NOT run on this PR.
This is a by-design side effect of the new feature-cohesive

will trigger the full CI matrix, providing safety net coverage
before any F-series work lands on `main`. Locally verified:

* test(acp-bridge): cover BridgeFileSystem injection seam + extract shared writeStderrLine (#4319 wenshao review)

Folds in wenshao review on #4319:

1. **[Critical]** zero test coverage for the F1 step 5 `BridgeFileSystem`
   delegation branches in `BridgeClient.writeTextFile` /
   `BridgeClient.readTextFile` and the factory's
   `opts.fileSystem` → constructor positional-arg forwarding.

   New `packages/acp-bridge/src/bridgeClient.test.ts` adds 6 tests
   covering:
   - writeTextFile delegates to injected fileSystem.writeText (inline
     proxy fully bypassed; `fakeFs.writeText` called with the original
     params; `readText` mock not invoked)
   - writeTextFile invalid-path call succeeds purely via the mock
     when fileSystem is injected (proof that the inline `fs.realpath`
     path doesn't run)
   - readTextFile delegates to injected fileSystem.readText
   - readTextFile propagates injection errors to the caller
   - inline-fallback regression guard: write actually hits disk via
     the inline proxy when fileSystem is omitted (real tmp file
     round-trip)
   - same for read

   Why these matter: the 7-arg `BridgeClient` constructor places
   `fileSystem` at the tail as optional. A reordering — or dropping
   the arg from `bridge.ts` factory's `new BridgeClient(..., opts.fileSystem)`
   call — would silently bypass the adapter in production and the
   inline `fs.writeFile` raw-path would run with no audit / trust /
   TOCTOU coverage. The delegation tests would catch that because
   the mock fileSystem would never be invoked.

2. **[Suggestion]** `writeStderrLine` was defined identically in
   `bridge.ts:117` and `bridgeClient.ts:30` (22 call sites across the
   two files). Both consumers live in the SAME `@qwen-code/acp-bridge`
   package, so the original "no reverse-dep on cli" justification
   doesn't apply within the package. Extracted to
   `packages/acp-bridge/src/internal/stderrLine.ts` — a single source
   of truth that future behavior changes (timestamp prefix, log
   level, structured field) can edit once. `internal/` subpath is
   intentionally not in `package.json`'s `exports`, keeping the
   helper package-private. `spawnChannel.ts` deliberately does NOT
   consume it (its stderr writes use `process.stderr.write(prefix +
   line + '\n')` directly because each line carries its own
   `[serve pid=… cwd=…]` line prefix).

* test(acp-bridge): cover defaultSpawnChannelFactory env scrubbing + fix bridge.ts comment refs (#4319 wenshao round 2)

Folds in wenshao review on #4319 round 2 — 1 Critical + 2 Suggestions:

1. **[Critical] spawnChannel.ts has 0 unit tests, security-critical
   paths untested.** Now that `defaultSpawnChannelFactory` is a public
   export of `@qwen-code/acp-bridge`, channels + IDE consumers can't
   rely on cli-package integration tests for env-scrubbing guarantees.

   Refactored the inline env-scrubbing logic into a pure exported
   helper `scrubChildEnv(source, scrubbed, overrides)`. Behavior is
   byte-identical to the pre-extraction inline implementation; the
   factory body now reads:

       const childEnv = scrubChildEnv(
         process.env, SCRUBBED_CHILD_ENV_KEYS, childEnvOverrides);

   Added `packages/acp-bridge/src/spawnChannel.test.ts` with 12 tests
   covering:
   - shallow-clone (no aliasing into live process.env)
   - QWEN_SERVER_TOKEN stripping
   - non-scrubbed vars pass through
   - override-add a new key
   - override-replace an existing key
   - override with undefined deletes the key (PR 14 fix #4247 wenshao R5)
   - override CANNOT re-introduce a scrubbed key (defense in depth)
   - override CANNOT undo the scrub by setting undefined for a scrubbed key
   - override-apply-after-scrub ordering invariant
   - empty overrides equals no overrides
   - multi-key scrub for forward-compat (the WARNING comment on
     SCRUBBED_CHILD_ENV_KEYS anticipates a future sandboxed-agent
     mode expanding the denylist; this verifies the loop already
     handles that)

   The killChild SIGTERM→SIGKILL escalation + STDERR_LINE_CAP_CHARS
   truncation are NOT covered yet — they require either real child
   processes or extensive node:child_process mocking; both are
   orthogonal to the env-scrubbing security guarantees wenshao
   explicitly called out, and can land as a follow-up if anyone
   wants the full surface tested.

2. **[Suggestion] bridge.ts comments referenced a "consolidated re-
   export block earlier in this file" that doesn't exist in acp-bridge
   (only in the cli shim).** Fixed both occurrences (~line 292, ~line
   310) to point at the actual local import + the package barrel
   re-export.

3. **[Suggestion] bridge.ts canonicalizeWorkspace re-export comment
   referenced `./fs/paths.ts`.** Updated to mention the full lift
   chain: extracted to `cli/src/serve/fs/paths.ts` in PR 18, then
   lifted here to `./workspacePaths.ts` in PR 22b/1.

Folds in 2 of 3 wenshao Suggestions from #4319 round 3:

1. `bridgeClient.test.ts:20` JSDoc said "the 14-arg constructor's
   positional slot" — typo I introduced when writing the test in
   `fbc92bccf`. The same docstring correctly says "the constructor
   takes 7 positional args" at line 25. Updated to "7-arg".

2. `bridge.ts:3461` `canonicalizeWorkspace` re-export JSDoc no longer
   references the historical `cli/src/serve/fs/paths.ts` location.
   Reads cleaner as a present-tense pointer to `./workspacePaths.ts`
   (where the implementation actually lives now post-PR 22b/1).
   Git history covers the lift chain; the docstring should describe
   current state.

DECLINED + tracked separately:

- **[Critical]** `closeSession` + `killSession` use module-scoped
  `channelInfo` instead of `channelInfoForEntry(entry)` — channel-
  overlap edge case can kill the wrong channel. Wenshao explicitly
  notes "pre-existing bug preserved by the lift" — F1's mechanical-
  lift scope shouldn't carry behavior fixes, and the fix needs a

Five small adoptions from a second-pass code-reviewer agent review on
F1 (no new external comments — pre-emptive cleanup before reviewer
returns):

1. **`bridge.ts:290-313`** — deleted two standalone "InvalidPermission
   OptionError / WorkspaceInit* / McpServer* lifted to bridgeErrors"
   tombstone comments. Pre-22b they were load-bearing (explained why
   the class wasn't `class`-defined inline at that file location).
   Post-F1 the symbols are imported at the top of the file and the
   comments sit between unrelated code (`writeServeDebugLine` /
   `MAX_DISPLAY_NAME_LENGTH` / `DEFAULT_INIT_TIMEOUT_MS`) with no
   anchor. Dead doc — removed.

2. **`README.md`** — `spawnChannel` entry now lists `scrubChildEnv`
   alongside `defaultSpawnChannelFactory` + `killChild` +
   `SCRUBBED_CHILD_ENV_KEYS`. Channels / VSCode IDE consume the
   package barrel so the helper should be visible in the inventory.

3. **`package.json:description`** — refreshed from the PR 22a wording
   ("EventBus, AcpChannel, in-memory channel, PermissionMediator
   interface") to include F1 additions (`createHttpAcpBridge` /
   `BridgeClient` / `defaultSpawnChannelFactory` / `BridgeFileSystem`).
   Visible on `npm view`-style tooling + IDE hover so worth keeping
   current.

4. **`bridgeClient.test.ts:92-115`** — swapped `/proc/no-such-file`
   for `/this/dir/never/exists/file.txt` and reworded the comment.
   `/proc/` is Linux-only; on macOS / Windows the inline proxy's
   dangling-symlink fallback would write through to a path under
   root rather than failing. Test passed regardless (mock assertion,
   not real disk) but the comment overstated portability.

5. **`spawnChannel.test.ts:36`** — added a comment block explaining
   why the test deliberately hand-rolls the SCRUBBED set instead of
   importing the production `SCRUBBED_CHILD_ENV_KEYS`. The
   decoupling is intentional (pure-function parameterized test +
   forward-guard for future denylist expansion) but a naive reader
   would think it's an oversight.

Folds 3 unresolved review comments from the post-merge thread on #4297
(wenshao via qwen-latest agent) into F1 (#4319). All 3 touch
`acp-bridge/src/bridge.ts` — the same file F1 already moves the lifted
factory into — so consolidating here saves opening a separate
follow-up PR and keeps the security narrative in one reviewable
commit. The 2 cross-package fixes (`core/src/memory/const.ts` test
gap + `cli/src/serve/runQwenServe.ts` malformed-context fallback)
will land as their own small PRs after F1 merges.

#### Fix 1 (wenshao Critical, #4297 thread): `fs.unlink(target)`
arbitrary-file-deletion primitive in `verifyParentWithinWorkspace`
'create'-cleanup

After `fs.open(target, 'wx')` creates the empty file at the real
parent, an attacker with local workspace write access can swap the
parent directory for a symlink (`docs/` → `/etc`). The cleanup's
`fs.unlink(target)` re-resolves the TEXTUAL path through the
attacker's freshly-planted parent symlink, deleting whatever file
exists at the external location.

Fix: drop the `fs.unlink(target)` line. The 0-byte file at the
pre-race location is harmless (0 bytes, inside the workspace we'd
already verified) — leaving it over deleting an arbitrary external
file is the right safety trade. Comment block explains the
reasoning so future maintainers don't re-introduce the unlink.

#### Fix 2 (wenshao Critical): `O_TRUNC` arbitrary-file-truncation
primitive in workspace-init 'overwrite' branch

`O_TRUNC` causes the kernel to truncate the file to zero bytes AT
`open(2)` SYSCALL TIME — strictly before `verifyParentWithinWorkspace`
runs. A parent-symlink TOCTOU race between
`canonicalizeExistingAncestor` and this `open()` zeros the file at
the attacker-redirected location (arbitrary-file-truncation
primitive against any file the daemon UID can open). The pre-fix
code's own comment on `verifyParentWithinWorkspace` acknowledged
this as "Acceptable residual posture for the Stage-1 trust model";
wenshao pushed back that arbitrary-file-zeroing exceeds the
Stage-1 trust budget.

Fix: drop `O_TRUNC` from the open flags. Truncation moves to AFTER
`verifyParentWithinWorkspace` succeeds, via `fh.truncate(0)` on the
fd we already hold. fd-based truncate does NOT re-resolve the path
— an attacker swapping the parent symlink after we open can't
redirect the truncation.

#### Fix 3 (wenshao Suggestion): `canonicalizeExistingAncestor`
missing `ELOOP` catch

Circular symlinks in the parent path (`a -> b`, `b -> a`) cause
`fs.realpath` to fail with `ELOOP`. Without catching it, the error
propagates as an unstructured HTTP 500 instead of the typed
`WorkspaceInitSymlinkError` (HTTP 400) the route handler expects
from the workspace-init race-detection family.

Fix: add `'ELOOP'` to the caught error codes alongside `'ENOENT'`
and `'ENOTDIR'`. Walking up the parent chain when ELOOP hits at a
sub-component preserves the existing "walk to the deepest extant
ancestor" contract — the deepest realpath-able ancestor still
dictates the canonical prefix.

#### Why no new tests in this commit

- Fix 1 is a single-line removal: any regression that re-adds the
  unlink would be caught by reviewing the diff; existing 174-test
  `httpAcpBridge.test.ts` integration suite confirms the create-path
  still works (file is created + closed correctly; only the
  attacker-cleanup branch changes).
- Fix 2 is a structural move (truncate from open-time to post-verify);
  the existing overwrite-init integration tests confirm the
  end-to-end behavior is unchanged (file ends up empty after init).
  Adding a TOCTOU race regression test requires controlled
  filesystem-race simulation that exceeds reasonable test infra
  scope for this PR.
- Fix 3 is a one-word addition to an error code list; the
  `canonicalizeExistingAncestor` helper is module-private and the
  integration test for circular-symlink → typed 400 would require
  exporting it OR setting up a real circular-symlink workspace.
  Both routes widen scope beyond the security fix itself; the
  high-level behavior is verifiable by the existing route-error-
  mapping test pattern + diff review.

A follow-up PR can add the integration tests once the security fix
itself has shipped; the immediate priority is closing the
arbitrary-file-deletion + arbitrary-file-truncation primitives.

* fix: post-merge Codex P2 fold-in — MCP restart disabled-tools normalization + SDK timeout headroom (#4319)

Folds in 2 P2 findings from a Codex review run on `git diff main...HEAD`
of F1 PR #4319. Both are pre-existing in code merged into
`daemon_mode_b_main` before F1 was created (#4282 PR 17), but they're
tiny tactical fixes (~25 LOC + 1 LOC) on the same integration branch
the same reviewer (wenshao) already engages with, so folding into F1
saves an extra follow-up PR cycle.

#### Fix 1: normalize disabled tool names during MCP restart refresh

`packages/cli/src/acp-integration/acpAgent.ts:1563-1566`

The bootstrap path in `cli/src/config/config.ts:1426-1434` applies a
4-step normalization to `tools.disabled`:
  1. typeof string filter
  2. .trim()
  3. drop empty after trim
  4. dedupe via Set

The MCP-restart refresh path only did step 1, then stored the raw
strings. `ToolRegistry` checks disabled tools with EXACT
`Set.has(tool.name)`, so a tool disabled at boot as `' Foo '` (or
`'Foo\n'`) is no longer matched after `restartMcpServer` and gets
silently re-registered. This contradicts the documented "toggle +
restart" workflow that #4282 PR 17 advertised.

Fix: mirror the bootstrap normalization verbatim before
`setDisabledTools`. Adds 6 lines + a 7-line comment pointing at the
bootstrap reference for future maintainers.

#### Fix 2: add headroom to MCP restart SDK timeout

`packages/sdk-typescript/src/daemon/DaemonClient.ts:102`

The SDK's `MCP_RESTART_DEFAULT_TIMEOUT_MS` was EXACTLY 300_000ms, the
same ceiling the daemon's own `MCP_RESTART_TIMEOUT_MS` uses for the
upper bound on a single MCP rediscovery. For restarts that finish
(or fail with a typed `McpServerRestartFailedError` JSON envelope)
near 300s, the client `AbortSignal` could fire BEFORE the daemon had
finished serializing + transmitting the response, yielding a client
`TimeoutError` even though the daemon was still within its own
budget.

Fix: bump to 330_000ms (10% / 30s headroom over the daemon ceiling).
Comment updated to call out the race + the rationale for the
specific headroom value. Callers needing tighter caps still pass
their own `timeoutMs` to `restartMcpServer`.

#### Why folded into F1 vs separate follow-up PRs

These are post-merge findings on `#4282 PR 17` code, not F1-introduced
regressions. Normally we'd track as separate follow-up issues (mirror
of the #4325 / `channelInfo` decline). But:

- Both fixes are TINY (~25 LOC + ~2 LOC including comment); the bridge
  security fold-in commit `7bd66c6e8` set the precedent of folding in
  small same-branch issues when the cost-benefit favors closing them
  immediately.
- Same reviewer (wenshao via qwen-latest agent) — won't be confused
  by the scope expansion; in fact the original PR 17 commenter is
  also the one who'd review the follow-up issue's fix.
- Both fixes target `daemon_mode_b_main`-only paths (MCP restart route
  added by PR 17 lives on the integration branch).
- Saves opening 2 trivial follow-up issues that would just sit until
  someone picks them up.

#### Verification

- sdk-typescript: 424/424 tests pass (no test hardcoded the old
  300_000 default — only the constant declaration itself referenced it)
- cli acp-integration: 282/282 tests pass (no test exercised the
  exact whitespace-bearing disabled-tools scenario, so no test
  changes were strictly required; a regression test would belong in
  a separate test-coverage PR alongside the const.ts test gap from
  the #4297 unresolved-comment thread)
- typecheck clean across cli + sdk-typescript

* refactor(daemon): drop dead try/catch around model_switched publish (BX9_p) (#4557)

* fix(serve): post-merge fixes for #4291 review (7 threads) (#4305)

* fix(serve): address qwen-latest review on merged #4291 (7 threads)

Seven post-merge findings from the qwen-latest review on #4291,
all real. Most are tightening fixes for issues introduced by the
earlier rounds of #4291 — the same security / DRY / observability
classes the original review surfaced, applied to surfaces that
weren't covered initially.

#1 (deviceFlow.ts:1179) — late-poll observer closure retained the
entire entry by reference (deviceCode/pkceVerifier BrandedSecrets +
cancelController) for the lifetime of the daemon if `provider.poll()`
never settled. Memory leak + indefinite secret retention. Destructure
the four fields the closure actually needs (deviceFlowId, providerId,
initiatorClientId, audit sink) so the entry is GC-eligible the
moment runPollTick returns.

#2 (server.ts) — `callerIsInitiator` was duplicated verbatim across
three locations: GET handler, toDeviceFlowStartResponseBody,
toDeviceFlowStateBody. The exact bug class #4291 was fixing was
"POST and GET diverged on the same redaction policy" — duplicating
the gate recreated the preconditions for divergence. Extracted to
shared `callerIsDeviceFlowInitiator(view, callerClientId)` helper
with the consolidated threat-model JSDoc. All three sites now call
the helper.

#3 (deviceFlow.ts:1110) — timeout callback constructed two separate
`DeviceFlowPollTimeoutError` instances (one for `signal.reason`, one
for the wrapper rejection). Each capture its own V8 stack trace,
and `signal.reason.stack` would diverge from the caught rejection's
stack — confusing for operators inspecting both. Build the sentinel
ONCE per timer fire and pass the same instance to both sites.

#4 (qwenDeviceFlowProvider.ts:273) — `Error.name` is a freely
assignable string property; a hostile fetch wrapper could set
`e.name = 'X\n[serve] FAKE LINE\x1b[31m'` to inject log lines or
ANSI sequences via the same vector we already closed for `oauthError`.
The non-OAuth catch path interpolated `${err.name}` raw. Apply the
same `sanitizeForStderr()` helper.

#5 (deviceFlow.ts:1551) — on the timeout path, `rawProviderError`
is undefined (deliberately, to skip the misleading
`provider.poll() threw (raw): ...` audit template), but that left
the audit hint field omitted entirely. Operators reading the
durable audit trail saw `errorKind: 'upstream_error'` with no signal
whether it was a hung IdP or a generic provider failure. Use
`result.hint` (which already carries the timeout-specific
`provider.poll() timed out after Nms; check IdP connectivity` text
built in the catch) so the audit matches the SSE event.

#6 (server.ts) — the `QWEN_SERVE_DEBUG` env-var check was inlined
in the GET route handler, duplicating the `isServeDebugMode()`
helper from `./debugMode.js` that workspaceAgents and
workspaceMemory already use. The inline copy also had a dead `?? ''`
fallback (the value is guaranteed truthy at that point per the
preceding check). Use the canonical helper.

#7 (deviceFlow.ts:1217) — late-rejection observer interpolated the
raw `lateErr.message` into the audit hint (truncated to 256 bytes,
but RFC 8628 `device_code` values fit comfortably in 256 bytes).
The provider's catch already uses the `name + length` redaction
pattern to prevent WAF-echoed `device_code`/PKCE leaks; the
registry layer was undoing that hardening because the same failure
settled late. Apply the same `name + length` pattern at the late-
rejection site.

Tests:
- Existing late-rejection test reseeded with a `device-code-secret-*`
  substring inside the long detail; hard-negative-asserts the seeded
  secret is absent from the audit + asserts the new
  `Error (message N bytes; raw suppressed)` shape.
- Existing poll-timeout test now also asserts: hint IS defined on
  the audit (not omitted), hint contains `'timed out after'` /
  `'check IdP connectivity'`, and `signal.reason instanceof
  DeviceFlowPollTimeoutError` (proves the single sentinel is
  shared between abort and reject).
- New `sanitizes control characters in attacker-controlled
  err.name` test in qwenDeviceFlowProvider.test.ts pins the round-4
  #4 fix with a hostile `e.name` containing `\n` + `\x1b[31m...`.

* fix(serve): address deepseek-v4-pro review on #4305 (4 threads)

Round-5 fold-in. Four findings from the deepseek-v4-pro review on
PR #4305 — all real, three are sister fixes for the same security
classes that #4305 already closed at adjacent surfaces.

#1 (deviceFlow.ts) — `pollTimedOut` race correctness. The flag was
set unconditionally inside the timer callback. If the provider
settled the wrapper at 29.9s, `finally` would call
`clearScheduled(pollTimer)` — but if the timer callback was already
queued for execution before the clear landed (a real possibility
in Node's event-loop ordering, even if not always observed in
practice), this branch could still run and incorrectly mark
`pollTimedOut`. Move the flag assignment to the catch block where
the settled cause is unambiguous via `instanceof
DeviceFlowPollTimeoutError`. New test pins the negative: provider
beats the timeout → no spurious `lost_late_poll_after_timeout`
audit even after ticking 2× the ceiling.

#2 (deviceFlow.ts) — late-rejection observer interpolated raw
`lateErr.name` into the audit hint without sanitization. Same
attacker-controlled vector closed at the provider layer for
`err.name` in round-4. Route through `sanitizeForStderr`.

#3 (deviceFlow.ts) — late-success observer interpolated
`latePollResult.kind` directly into the audit template. While the
typed shape is `'pending' | 'slow_down' | 'success' | 'error'`, a
non-conforming provider could return an arbitrary string. Same
log-injection vector. Route through `sanitizeForStderr`.

#4 (qwenDeviceFlowProvider.ts → deviceFlow.ts) —
`sanitizeForStderr` only stripped ASCII C0/C1 + DEL; bypass via
Unicode lookalikes:
  - U+2028/U+2029: LINE/PARAGRAPH SEPARATOR (newline-equivalent in
    most Unicode-aware terminals — most direct log-forging vector)
  - U+200B–U+200F: zero-width chars + LRM/RLM
  - U+202A–U+202E: bidirectional override controls
  - U+FEFF: BOM / ZWNBSP

A malicious IdP returning `slow_down
[serve] FAKE` in
`oauthError` would otherwise still forge log lines.

Architectural change: `sanitizeForStderr` was previously private to
`qwenDeviceFlowProvider.ts`. To address #2/#3, the registry layer
needs to call it too. Lifted into `deviceFlow.ts` (the foundation
module) and re-imported from the provider. Single source of truth;
the regex is now a module-level constant compiled once with explicit
`\uXXXX` escapes (via `String.raw` so the source is greppable, not
literal-Unicode-laden).

Tests:
- `does NOT attach late-poll observer when the provider beats the
  timeout` — N1 race regression
- `sanitizes hostile latePollResult.kind in late-observer audit` — N3
- `sanitizes hostile lateErr.name in late-rejection observer audit` — N2
- `sanitizes Unicode lookalike controls (U+2028 LINE SEPARATOR,
  bidi, ZWNBSP) in oauthError` — N4

* fix(serve): address gpt-5.5 + qwen-latest review on #4305 round-5 (5 threads)

Round-6 fold-in. Five findings split between maintainability,
security hardening, and a real defensive bug.

#1 (qwenDeviceFlowProvider.test.ts) — gpt-5.5: round-5 #4 test
embedded U+2028 / U+200E / U+FEFF as literal characters in source.
Invisible in GitHub diffs / most editors; the negative
`not.toContain('')` looked like an empty-string check. Rewrote
the payload + assertions to use named `\uXXXX`-bound constants.
Also added a companion test exercising U+2066–U+2069 (round-6 #5
below).

#2 (deviceFlow.ts) — qwen-latest: the late-poll observer's
`void tracked.then(...)` was missing a terminal `.catch(() => {})`.
A synchronous throw inside either handler (e.g., a misbehaving
`audit.record`: backpressure, malformed payload, sink out-of-disk)
would reject the derived promise unhandled. On Node 22's default
`--unhandled-rejections=throw`, that crashes the daemon. Added the
terminal `.catch(() => {})` matching the persist-tracker pattern.
New test injects a poison audit sink that throws specifically on
the `lost_late_poll_after_timeout` call; asserts `flushAsync()`
resolves cleanly.

#3 (deviceFlow.ts) — qwen-latest: the `case 'error'` audit-record
hint interpolated `rawProviderError` (raw `err.message`) without
`sanitizeForStderr`. Per ES2019+ `JSON.stringify` no longer escapes
U+2028/U+2029 — those would still forge log lines downstream
through file/stdout audit sinks. Apply the same sanitizer used on
every other provider-controlled audit path. New test pins a hostile
provider message containing U+2028 + ANSI escape and asserts
neither survives.

#4 (deviceFlow.ts) — qwen-latest: the round-5 #1 comment claimed
"`DeviceFlowPollTimeoutError` isn't exported as a public DeviceFlow
contract", but it IS `export class` (the test file constructs it
directly for fixtures). With `pollTimedOut = true` keyed solely on
`instanceof`, a future provider that imports + throws the class
would spoof the registry's "I caused the timeout" signal —
attaching a phantom late-poll observer.

Fix: introduce a runtime brand `_isRegistryTimeout: boolean` on the
class (default `false`) plus an internal-only
`makeRegistryPollTimeoutError(ms)` helper that sets the brand to
`true`. The brand is set ONLY at the registry's race-timer
construction site. Both gates updated:
  - `if (err instanceof X && err._isRegistryTimeout === true)` in
    the catch (for `pollTimedOut`)
  - `if (lateErr instanceof X && lateErr._isRegistryTimeout === true)`
    in the late-rejection self-filter

A provider-thrown brand-false instance now flows through the
generic provider-throw audit path — correctly auditing the misuse
rather than silently swallowing it. Repurposed the original "no
double-audit when registry's own DeviceFlowPollTimeoutError is
late-rejected" test (which was actually exercising the brand-false
path) into the inverted assertion: brand-false provider throw IS
audited as a real failure. Removed the orphaned old assertion; the
brand-true happy path is implicitly covered by the hanging-provider
test (which exercises the registry-built timeout end-to-end).

#5 (deviceFlow.ts) — qwen-latest: `sanitizeForStderr` regex covered
U+202A–U+202E (bidi embedding/override) but missed U+2066–U+2069
(LRI/RLI/FSI/PDI). These are the primary CVE-2021-42574
("Trojan Source") attack vectors — a hostile IdP swapping U+2066
for U+202D achieves the same visual reordering and would have
bypassed the round-5 filter entirely. Extended the regex range and
JSDoc; new test exercises U+2066/U+2068/U+2069 in `oauthError` and
asserts none survive while substantive ASCII parts remain.

* fix(serve): post-merge P2 corrections from Codex review on #4282

Follow-up to PR #4282 (Wave 4 PR 17) addressing four P2 issues
flagged by Codex's `/review` after the squash-merge to main:

P2-1 — Read the workspace context filename for init
  `qwen serve` parent never goes through `loadCliConfig`, so the
  process-global `getCurrentGeminiMdFilename()` stays on the default
  `QWEN.md` even when the workspace configures
  `context.fileName: 'AGENTS.md'`. `runQwenServe` now snapshots the
  workspace's merged setting at boot and forwards via
  `BridgeOptions.contextFilename`, so init writes the same file the
  ACP child reads.

P2-2 — Restart MCP servers with a fresh disabledTools snapshot
  `Config.disabledTools` was frozen at construction time;
  `setWorkspaceToolEnabled` only updated settings.json. The
  documented "toggle + restart" workflow re-registered just-disabled
  tools because rediscovery still saw the bootstrap snapshot. Added
  `Config.setDisabledTools()` plus a re-read at the ACP restart
  handler so `discoverMcpToolsForServer` honors the latest set.

P2-3 — Match the SDK timeout to the daemon's restart budget
  Bridge waits up to 300s for stdio MCP discovery; SDK helper used
  the client-wide 30s default and aborted valid slow restarts.
  Added a per-call `timeoutMs` plumbed through `fetchWithTimeout`,
  defaulting `restartMcpServer` to 5 minutes.

P2-4 — Reject symlinked parent directories before init writes
  `lstat(target)` only checked the final component; a symlinked
  parent (e.g. `docs -> /tmp` with `context.fileName:
  'docs/QWEN.md'`) would let `writeFile` follow the link and create
  / truncate outside `boundWorkspace`. Added
  `canonicalizeExistingAncestor` (walks up through ENOENT to the
  deepest extant ancestor, then `realpath`s) and verifies the
  canonical parent stays within the canonical workspace.

5 new tests (4 bridge / 2 SDK):
- contextFilename snapshot honored
- parent-symlink escape rejected
- nested real subdir accepted
- restartMcpServer survives 1.2s response with 1s default timeout
- restartMcpServer honors a 50ms caller override

* fix(serve): fold-in 1 — address 16:32:44-round review on #4282

Follow-up addressing the 8 unresolved review threads opened on PR
shipping in this same #4297; addresses correctness gaps + missing
test coverage that would otherwise let regressions ride into main.

Behavior fix:
- broadcastWorkspaceEvent gains a `skipSessionId` parameter; when
  `setSessionApprovalMode` runs with `persist:true`, the broadcast
  skips the requesting session so it doesn't receive the same
  `approval_mode_changed` event twice (once via session-scoped
  publish + once via broadcast). The SDK reducer's
  `approvalModeChangedCount` now increments by 1, not 2, on the
  requesting client (peers still see 1 via the broadcast).
  Addresses #3260501134.

Observability + posture:
- broadcastWorkspaceEvent now mirrors PR 16's publishWorkspaceEvent
  member: per-entry success/failure accounting + an "ALL buses
  dropped" stderr elevation. The previous local helper silently
  swallowed every publish failure. Addresses #3260501126.
- WorkspaceInitPathEscapeError + WorkspaceInitSymlinkError typed
  classes for the two boundary guards in initWorkspace, mapped to
  HTTP 400 by sendBridgeError. Previous generic `Error` fell
  through to the 500 handler, telling operators "daemon broken"
  when the actual fix was workspace-config correction. Addresses
  #3260501161.

Public surface symmetry:
- Re-export McpServerNotFoundError, McpServerRestartFailedError,
  WorkspaceInitPathEscapeError, WorkspaceInitSymlinkError from the
  serve barrel. External embeds matching these via `instanceof`
  no longer need deep imports. Addresses #3260501163.

Test coverage:
- restartMcpServer bridge tests (5): success + event broadcast,
  soft-skip + refused event, McpServerNotFoundError translation,
  McpServerRestartFailedError translation, originator clientId
  stamping. Addresses #3260501141.
- sendBridgeError mapping tests (4): McpServerNotFoundError → 404,
  McpServerRestartFailedError → 502, WorkspaceInitPathEscapeError
  → 400, WorkspaceInitSymlinkError → 400. Addresses #3260501148.
- initWorkspace boundary guard tests (2 added): symlink-at-target
  rejected, contextFilename '../outside.md' rejected. Addresses
  #3260501157.
- TrustGateError tests assert the typed class via `.toThrow(TrustGateError)`,
  not just message text. Addresses #3260501165.

Also updates the existing fold-in 4 S2 broadcast test to reflect
the new no-duplicate semantics on the requesting session.

* fix(serve): fold-in 2 — copilot + wenshao review on #4297

Round-2 reviewer adoption on the same PR:

Critical fixes:
- `restartMcpServer` JSDoc documents `timeoutMs: 0` as "disable the
  timeout entirely", but the `> 0` guard in `fetchWithTimeout`
  rejected `0` and silently fell back to the 30s client default.
  Loosened the guard to `>= 0` so `0` flows through to the
  no-timeout branch via the existing truthiness check; NaN /
  negative inputs still coerce to the client default. Addresses
  duplicate reports from copilot (#3260577538) and wenshao
  (#3260661833).
- TS2322 in the slow-fetch test stub: `resolveResponse` was typed
  against `import('undici-types').Response` but assigned a
  `(v: Response) => void`. Re-typed against the global `Response`
  throughout. Caught only by tsc runs that include the test
  files. Addresses #3260663072.

Test fidelity:
- Slow-fetch stub now observes `init.signal` and rejects on abort,
  so a regression that drops the per-call `timeoutMs` override
  will reliably fail the test instead of resolving after the
  timer fired (false-negative coverage). Addresses #3260577600.
- New test pinning the `timeoutMs: 0` semantics: 1ms client
  default + a stub that resolves after 50ms. Without the `>= 0`
  fix, the call would abort at 1ms; with it, the explicit
  `0` disables the timer and the call completes.

Bug fixes:
- `runQwenServe.contextFilenameForInit` previously called
  `String(arr[0])` on the array branch, producing a literal
  `"[object Object]"` filename for hand-edited bad data. Now
  validates each element with `typeof === 'string'` and falls
  back to `undefined` (so the bridge uses its
  `getCurrentGeminiMdFilename()` default) when no string is
  found. Addresses #3260577641.

Documentation drift:
- `Config.getDisabledTools()` JSDoc rewritten to describe the
  mutable-via-`setDisabledTools()` semantics introduced by P2-2,
  and the "registration-time only / no retroactive unregister"
  contract that pairs with it. Old comment claimed the set was
  frozen at construction. Addresses #3260577677.

Observability:
- `acpAgent` MCP-restart `loadSettings` failure now surfaces a
  stderr line naming the server + the underlying error, instead
  of silently swallowing it. The documented "toggle + restart"
  workflow used to break with zero diagnostic when settings.json
  was corrupted or unreadable. Addresses #3260663303.

Code organization:
- Moved `canonicalizeExistingAncestor` after `describeStatKind` so
  the latter's JSDoc is no longer orphaned (TypeScript only
  associates the last `/** ... */` block before a declaration).
  Addresses #3260668618.

* fix(serve): fold-in 3 — read merged scope on MCP restart refresh

Critical bug from wenshao review (#3260725526) on PR #4297:
the P2-2 acpAgent re-read narrowed `Config.disabledTools` to
`SettingScope.Workspace` alone, dropping User / System scope
entries. The bootstrap Config received `merged.tools?.disabled`
(union of all scopes), so user-level / system-level disables
worked at boot — but the first `mcp restart` would replace the
in-memory set with the workspace scope alone, silently re-enabling
any tool that was disabled at a higher scope but absent from the
workspace file.

The asymmetry vs. the persist-write path is deliberate and
documented:
- Reads (here): merged — match the bootstrap Config snapshot,
  preserve user/system policy.
- Writes (`runQwenServe.persistDisabledTools`): workspace scope —
  don't bake higher-scope entries into the workspace file
  (per-#4282 fold-in 1 H2 fix).

Two paths look alike but answer different questions.

* fix(test): fold-in 4 — wire timeoutMs:0 stub to init.signal

Critical follow-up from wenshao (#3260810242) on PR #4297:
the new `timeoutMs: 0` regression test (added in fold-in 2)
inherited the same flaw it was meant to prevent — the slow-fetch
stub didn't observe `init.signal`, so a regression that ignored
the `0` override would fire the AbortController at the 1ms client
default but the stub would keep the promise pending. The 50ms
`resolveResponse` would win, the test would still pass, and the
documented "0 disables timeout" contract would be unprotected.

Mirrored the listener pattern already used by the two sibling
tests in fold-in 2 — `init.signal.addEventListener('abort', () =>
reject(...))`. Now a regression that re-rejects `0` triggers the
abort, the stub rejects, the test fails.

8/8 restartMcpServer SDK tests pass; SDK typecheck clean.

* fix(serve): fold-in 5 — TOCTOU + setDisabledTools coverage

Two new critical reviews from wenshao on PR #4297:

C1 — TOCTOU between lstat and writeFile (#3260836305):
The `lstat(target)` symlink check and the subsequent `writeFile`
were two separate syscalls, leaving a race window where a local
attacker with workspace write access could substitute a symlink
between them. With `force: true`, `writeFile` would follow the
link and truncate an external target.

The `action === 'created'` path now uses `fs.open(target, 'wx')`
(O_WRONLY|O_CREAT|O_EXCL), which atomically refuses any
pre-existing inode (regular file, dir, OR symlink) at the target
path. EEXIST after the absence check most plausibly means a
race-created symlink, so we throw `WorkspaceInitSymlinkError(kind:
'target')` — same typed class the route maps to 400.

The `force: true` overwrite path retains the existing TOCTOU as a
documented limitation; closing it requires `O_NOFOLLOW`-aware open
which the post-PR18 `WorkspaceFileSystem` migration will provide.

C2 — P2-2 zero test coverage (#3260836302):
The `setDisabledTools` runtime sync was the only Wave-4 P2 fix
without a dedicated test. Added 5 Config-level tests:
- Initializes from `disabledTools` ConfigParameters
- Defaults to empty set when omitted
- `setDisabledTools` replaces the live snapshot
- Defensive copy: caller-set mutations don't leak into the live snapshot
- Accepts an empty set (clears live snapshot)

Plus a TOCTOU regression test in httpAcpBridge.test.ts that
spies fs.lstat / fs.readFile to simulate the race window:
pre-creates a symlink, makes lstat lie about it, asserts the
'wx' open catches the racing inode and throws the typed
`WorkspaceInitSymlinkError(kind: 'target')`.

1622/1622 unit tests pass; typecheck clean across cli /
sdk-typescript / core.

* fix(serve): fold-in 6 — count actual skips in broadcast alarm

DeepSeek review on #4297 (#3261079572):
`broadcastWorkspaceEvent` unconditionally subtracted 1 from the
`eligible` recipient count whenever `skipSessionId` was set, even
when the id matched zero live sessions (caller mistake, stale id,
or the matching session was just torn down between resolution and
broadcast). In a single-session workspace that's the difference
between `eligible = 0` (alarm suppressed) and `eligible = 1`
(alarm fires when the publish failed) — silently losing the
all-dropped breadcrumb the telemetry was meant to surface.

Today's call sites pass real session ids so the bug doesn't
manifest in practice, but the defensive shape is small: track
`skippedCount` inside the loop and subtract that, so the alarm
condition is self-consistent regardless of how the caller mis-uses
the param.

162/162 bridge tests pass; CLI typecheck clean.

* fix(serve): fold-in 7 — close overwrite TOCTOU, harden boot + diagnostics

Round-7 review on PR #4297. Three critical fixes + one suggestion
test, plus a regression test for the overwrite TOCTOU close.

C1 — force:true overwrite TOCTOU (#3262615446):
The fold-in 5 fix only closed the `'created'` action via 'wx';
the `'overwrote'` branch still used plain `fs.writeFile`, so a
local writer could swap the verified regular file to a symlink
between the lstat/readFile checks and the write and have the
forced overwrite truncate an external target. Switched to
`fs.open(target, O_WRONLY | O_TRUNC | O_NOFOLLOW)` — `O_NOFOLLOW`
makes open() fail with ELOOP on a symlink at the final component
even under race. ELOOP / ENOENT (race-deleted) translate to
`WorkspaceInitSymlinkError(kind: 'target')` so the route still
maps to a structured 400 instead of a generic 500.

C2 — settings.json corrupt blocks daemon boot (#3262625091):
`loadSettings(boundWorkspace)` at boot had no try/catch — a
corrupted, malformed, or temporarily unreadable settings file
threw synchronously and prevented daemon startup. Pre-PR this
never happened because settings were read lazily inside request
handlers. Wrapped in try/catch with stderr fallback so the daemon
keeps booting (with the bridge's default context filename) when
the file is broken.

C3 — malformed `tools.disabled` clears policy silently (#3262625101):
When `merged.tools?.disabled` is present but not an array
(boolean / string / object from a hand-edited settings.json), the
ternary `Array.isArray(...) ? ... : []` substituted an empty list
without firing the surrounding catch block. After an MCP restart
every disabled tool would silently re-register. Added an explicit
`!Array.isArray && !== undefined` check that stderr-logs the
malformed type before clearing — operators see the
misconfiguration instead of a stealth re-enable.

S1 — contextFilename extraction tested (#3262690842):
Lifted the inline `firstStringInArray` + branching into an
exported `extractContextFilename(value: unknown)` helper and
added `runQwenServe.test.ts` with 5 tests covering the four
branches the suggestion called out: non-empty string, array with
strings, array with no strings, non-string non-array.

Plus a TOCTOU regression test for the overwrite path that
verifies `O_NOFOLLOW` returns `WorkspaceInitSymlinkError(kind:
'target')` when the file is race-substituted with a symlink
behind the lstat/readFile mocks.

S2 (acpAgent restart-handler integration test #3262690845) is
deferred — Config-level coverage of `setDisabledTools` already
locks the load-bearing surface (5 tests in fold-in 5), and
adding a full acpAgent integration test requires heavy ext-method
plumbing. The new C3 stderr diagnostic plus existing tests give
us the regression signal we need without that scaffolding.

1627/1627 unit tests pass; typecheck clean across cli /
sdk-typescript / core / acp-bridge.

* fix(serve): fold-in 8 — split ELOOP / ENOENT diagnostic in overwrite path

qwen-latest review on PR #4297 (#3262861754):
The fold-in 7 ELOOP/ENOENT branch shared one error message that
said "swapped to a symlink." That's accurate for ELOOP (genuine
O_NOFOLLOW rejection — likely an attack race) but misleading for
ENOENT in the overwrite path: there `readFile` just succeeded
proving the file existed, so ENOENT means the file was DELETED
between the content check and the open — a benign race with a
concurrent writer (git checkout, editor save, lockfile rename),
NOT a symlink swap. An operator seeing the symlink language for
a benign delete would `ls -la`, see no symlink, and waste time
hunting an attack that didn't happen.

Split into two messages:
- ELOOP: "swapped to a symlink between the content check and the
  overwrite — refusing to follow it"
- ENOENT: "deleted between the content check and the overwrite
  (likely a concurrent writer) — refusing to recreate blindly"

Both still surface as `WorkspaceInitSymlinkError(kind: 'target')`
so the route maps to a structured 400; the class doubles as the
workspace-init race-condition bucket with kind='target' meaning
"target inode misbehaved at write time" generally.

Updated the existing fold-in 7 TOCTOU test to assert the ELOOP
message specifically, and added a new ENOENT race-delete test
that mocks lstat/readFile to land on the overwrote action against
a non-existent path — verifies the message says "deleted" and
NOT "swapped to a symlink."

170/170 bridge tests pass; CLI typecheck clean.

* fix(serve): fold-in 9 — route MCP restart through registry cleanup wrapper

gpt-5.5 critical review on PR #4297 (#3263088414):

The fold-in 5 P2-2 fix refreshed `Config.disabledTools` from merged
settings, but then called `manager.discoverMcpToolsForServer()`
directly — bypassing the `ToolRegistry.discoverToolsForServer`
wrapper that PURGES the server's existing `DiscoveredMCPTool`
entries (and `revealedDeferred` markers) plus its prompts before
rediscovery. Without the cleanup, `registerTool` only consulted
the refreshed `disabledTools` set for NEWLY-discovered tools —
entries already in the registry from the prior MCP boot kept
serving requests. Net effect: toggle-disable-then-restart
silently left the disabled tool live, breaking the documented
"toggle + restart" workflow that P2-2 was meant to fix.

Routed through `toolRegistry.discoverToolsForServer(serverName)`
which:
1. Removes existing `DiscoveredMCPTool` entries for this server
2. Drops their `revealedDeferred` reveal state
3. Removes the server's prompts via `removePromptsByServer`
4. THEN delegates to `manager.discoverMcpToolsForServer` for the
   actual reconnect + rediscover

The pre-discovery budget / in-flight checks still go through the
`manager` reference (which is the same object the registry
wrapper would forward to) — so soft-skip semantics for
`budget_would_exceed`, `in_flight`, `disabled` are preserved.

CLI typecheck clean; 403/403 server + bridge tests pass.

* fix(serve): fold-in 10 — qwen-latest 05:45-round review on #4297

5 review threads from qwen-latest's late round on PR #4297 (now closed
in favor of #4313 against `daemon_mode_b_main`). 1 critical + 4
suggestions, all adopted.

C1 — extractContextFilename / getCurrentGeminiMdFilename divergence
(#3263954685): with `context.fileName: ['  ', 'AGENTS.md']`, the
daemon parent's `extractContextFilename` (which skips empty entries)
wrote `AGENTS.md`, but the ACP child's `getCurrentGeminiMdFilename`
(which returned `arr[0]` unconditionally) read `''`. The init'd file
was orphaned. Aligned `getCurrentGeminiMdFilename` to skip empty
entries with the same semantics, falling back to
`DEFAULT_CONTEXT_FILENAME` when all entries are empty.

S2 — WorkspaceInitSymlinkError reused for non-symlink races
(#3263954690): the EEXIST race-create and ENOENT race-delete cases
were surfacing as `code: 'workspace_init_symlink'`, misleading
operators into hunting symlink attacks for benign concurrent-
modification windows. Split into a sibling `WorkspaceInitRaceError`
class (`kind: 'eexist' | 'enoent'`, HTTP code
`workspace_init_race`). The genuine symlink class stays for ELOOP,
lstat-detected target symlinks, and parent-realpath escapes.

S3 — fsConstants.O_NOFOLLOW defensive `?? 0` (#3263954697): matches
the existing codebase convention in
`core/src/utils/{sessionStorageUtils,gitDiff}.ts` and
`cli/src/ui/utils/customBanner.ts`. Functionally a no-op (JS
bitwise coerces undefined to 0) but consistent.

S5 — Parent-directory TOCTOU still open (#3263954707): O_NOFOLLOW
only protects the final path component; a local writer could swap
a real parent dir for a symlink between
`canonicalizeExistingAncestor` and `fs.open`. Added
`verifyParentWithinWorkspace` post-open helper that re-realpaths
`path.dirname(target)` and refuses with
`WorkspaceInitSymlinkError(kind: 'parent')` if the parent moved.
On the create path (where we just opened with `'wx'`), the failure
also unlinks the file we just made best-effort. Residual race
window narrowed from "between pre-check and open" to "between
post-open realpath and writeFile" — sub-millisecond, documented as
accepted Stage-1 trust posture.

S4 — broadcastWorkspaceEvent vs publishWorkspaceEvent stale comment
(#3263954688): the "now removed" comment was inaccurate (5 call
sites still use the closure). Replaced with an accurate
description of why both coexist (factory closure can't `this`-call
proxy member; closure also takes `skipSessionId` for persisted
approval-mode mirror) and a TODO marker for future helper extraction.

Two existing tests updated to assert the new `WorkspaceInitRaceError`
class for EEXIST / ENOENT scenarios (the symlink-class assertions
are preserved for ELOOP / lstat / parent cases).

1759/1759 unit tests pass; typecheck clean across all 4 packages.

* feat(acp-bridge): F1 — acp-bridge package self-sufficiency (#4175 mechanical lift + BridgeFileSystem seam) (#4319)

* refactor(acp-bridge): lift defaultSpawnChannelFactory to acp-bridge/spawnChannel (#4175 F1 step 1)

First mechanical lift of #4175 F1 (acp-bridge package self-sufficiency).
Moves the production spawn factory + its `killChild` helper +
`SCRUBBED_CHILD_ENV_KEYS` denylist + `KILL_HARD_DEADLINE_MS` constant
from `cli/src/serve/httpAcpBridge.ts` (~283 lines) to
`@qwen-code/acp-bridge/spawnChannel`. This unblocks
`channels/base/AcpBridge.ts` and `vscode-ide-companion`'s
acpConnection from each reimplementing the child lifecycle — they can
now consume the same primitive.

Backward compatible: `cli/src/serve/httpAcpBridge.ts` imports the
lifted factory and re-exports it, so existing references in
`cli/src/serve/index.ts:90` and the factory's own internal usage
(`opts.channelFactory ?? defaultSpawnChannelFactory`) keep resolving.
Bridge tests that mock `defaultSpawnChannelFactory` via
`BridgeOptions.channelFactory` are unaffected.

Side cleanups: drops `spawn` / `ChildProcess` / `Readable` / `Writable`
/ `ndJsonStream` / `MissingCliEntryError` imports from
httpAcpBridge.ts (all only used by the lifted spawn factory).

* refactor(acp-bridge): lift BridgeClient + permission types to acp-bridge/bridgeClient (#4175 F1 step 2)

Second mechanical lift of #4175 F1 (acp-bridge package self-sufficiency).
Moves `BridgeClient` class (~700 LOC) + `PendingPermission` interface +
`PermissionResolutionRecord` interface + `MAX_RESOLVED_PERMISSION_RECORDS`
constant + early-event capacity constants + `describeStatKind` and
`sliceLineRange` helpers from `cli/src/serve/httpAcpBridge.ts` to
`@qwen-code/acp-bridge/bridgeClient`.

Design choice for SessionEntry boundary: introduce a minimal
`BridgeClientSessionEntry` interface in bridgeClient.ts with only the
four fields BridgeClient actually reads from the factory's richer
`SessionEntry` (`sessionId`, `events`, `pendingPermissionIds`,
`activePromptOriginatorClientId`). The factory's `SessionEntry`
structurally satisfies it — TypeScript's structural typing enforces
the match at the `resolveEntry` callback signature, so no explicit
conversion is required and the bridge package stays free of daemon-host
session-bookkeeping types.

Cross-package writeStderrLine handling: inline the 3-line helper in
bridgeClient.ts (mirrors the spawnChannel.ts pattern from F1 step 1)
so acp-bridge has no reverse dependency on `cli/src/utils/stdioHelpers`.

httpAcpBridge.ts shrinks from 4406 LOC to 3647 LOC (-759 lines).
Removed ACP SDK imports that only BridgeClient consumed: `Client`,
`RequestPermissionRequest`, `WriteTextFileRequest`,
`WriteTextFileResponse`, `ReadTextFileRequest`, `ReadTextFileResponse`,
`SessionNotification`. Kept the ones the factory still uses
(`CancelNotification`, `PromptRequest`, `RequestPermissionResponse`,
`SetSessionModelRequest`, `SetSessionModelResponse`).

Backward compatible: httpAcpBridge.ts re-exports `BridgeClient`,
`BridgeClientSessionEntry`, `PendingPermission`,
`PermissionResolutionRecord`, and `MAX_RESOLVED_PERMISSION_RECORDS` so
the `ChannelInfo.client: BridgeClient` field declaration below + any
embedder reaching into these types keep resolving.

* refactor(acp-bridge): lift createHttpAcpBridge factory to acp-bridge/bridge (#4175 F1 step 3)

Third + final mechanical lift of #4175 F1 (acp-bridge package
self-sufficiency). Moves the `createHttpAcpBridge` factory closure
(~3000 LOC) + `ChannelInfo` + `SessionEntry` interfaces + factory-only
helpers (`canonicalizeExistingAncestor`, `verifyParentWithinWorkspace`,
`withTimeout`, `isServeDebugLoggingEnabled`, `writeServeDebugLine`,
`hasControlCharacter`) + factory constants (`DEFAULT_INIT_TIMEOUT_MS`,
`MCP_RESTART_TIMEOUT_MS`, `DEFAULT_MAX_SESSIONS`, `MAX_EVENT_RING_SIZE`,
`DEFAULT_PERMISSION_TIMEOUT_MS`, `DEFAULT_MAX_PENDING_PER_SESSION`,
`MAX_DISPLAY_NAME_LENGTH`) from `cli/src/serve/httpAcpBridge.ts` to
`@qwen-code/acp-bridge/bridge`.

`cli/src/serve/httpAcpBridge.ts` shrinks from 3647 LOC to 97 LOC — a
pure re-export shim that preserves every existing relative import
path (`./httpAcpBridge.js`) so `server.ts`, `runQwenServe.ts`,
`workspaceAgents.ts`, `workspaceMemory.ts`, `index.ts`, plus the bridge
test suite, keep resolving without any call-site changes.

The new `bridge.ts` reuses what was already in acp-bridge (errors,
types, options, status helpers, channel types, event bus, workspace
paths) via local relative imports — no reverse dependency on `cli`.
`writeStderrLine` is inlined at the top of `bridge.ts` (same pattern as
`spawnChannel.ts` + `bridgeClient.ts` from F1 steps 1-2) so the
package self-contained promise holds.

Cumulative F1 impact across the 3 mechanical lift steps:
- httpAcpBridge.ts: 4682 LOC → 97 LOC (-4585 lines; the original file
  was 98% bridge core, 2% backward-compat re-exports)
- 3 new files in acp-bridge: spawnChannel.ts (~270 LOC), bridgeClient.ts
  (~745 LOC), bridge.ts (~3515 LOC)
- All daemon-host concerns (env snapshot, daemon preflight cells)
  remain in `cli/src/serve/daemonStatusProvider.ts` and reach the
  bridge through the `BridgeOptions.statusProvider` seam frozen by
  PR 22b/2.

`packages/cli/src/serve/httpAcpBridge.test.ts` (~6600 LOC) is
intentionally NOT moved in this commit — it currently imports
`createHttpAcpBridge` / `defaultSpawnChannelFactory` / `BridgeClient`
via the cli shim and keeps passing without changes. Moving it to
`acp-bridge/src/bridge.test.ts` is a follow-up worth tracking
separately so the production-code lift can land + be reviewed cleanly.

The `BridgeFileSystem` injection seam (originally bundled into F1 as
the 22b' scope) is also deferred to a follow-up so the mechanical lift
stays mechanical — design + implementation of the fs injection is its
own discussion.

* feat(acp-bridge): add BridgeFileSystem injection seam (#4175 F1 step 5, 22b' scope)

Adds the `BridgeFileSystem` injection seam originally scoped as #4175
22b'. When a `BridgeFileSystem` is wired through
`BridgeOptions.fileSystem`, `BridgeClient.readTextFile` and
`BridgeClient.writeTextFile` delegate to it instead of running their
inline `fs.realpath` / `fs.writeFile` / `fs.readFile` proxy.

This unblocks production `qwen serve` plumbing PR 18's
`WorkspaceFileSystem` (TOCTOU guards, symlink-substitution checks,
trust gate, `.gitignore`, audit hooks) into the ACP fs methods —
closing the `ws.ts:613` follow-up thread that has been tracked since
PR 18 landed. The serve-side adapter that wraps `WorkspaceFileSystem`
+ the `runQwenServe` wiring are intentionally split into the
immediate-follow-up so this PR stays focused on the seam design.

Backward compatible: `fileSystem` is optional on `BridgeOptions`.
Tests, Mode A in-process consumers, channels (`packages/channels/base/
AcpBridge.ts`), and the VSCode IDE companion all keep working
unchanged — they omit the field and `BridgeClient` falls through to
the inline proxy that has been the Stage 1 default since #3889.

API:
- `BridgeFileSystem.readText(params: ReadTextFileRequest):
  Promise<ReadTextFileResponse>`
- `BridgeFileSystem.writeText(params: WriteTextFileRequest):
  Promise<WriteTextFileResponse>`

The interface mirrors ACP SDK request/response types directly so the
adapter does the minimum amount of translation (`{ path, content }`
↔ `WorkspaceFileSystem`'s `ResolvedPath` brand types + options bag).

and listed `BridgeClient` / `createHttpAcpBridge` /
`defaultSpawnChannelFactory` under "What's not here yet" — both
contradicted by this PR. Updated:

- README lift-history table now shows PR 22a / 22b/1 / 22b/2 as

Folds in 3 of 4 Copilot inline comments from #4319 review:

1. `bridgeClient.ts` writeTextFile preserveMode comment said "fall
   through to umask defaults" for new files, but the code passes
   `mode: preserveMode?.mode ?? 0o600` to `fs.writeFile`. Updated the
   "BkwQW" comment + the inner catch-block comment to clarify that
   new files actually get the `0o600` default applied at writeFile
   time (NOT umask defaults — the explicit `mode` arg bypasses umask
   for atomicity per the `Blehd` comment block).

2. `bridgeFileSystem.ts` JSDoc referenced
   `cli/src/serve/bridgeFileSystemAdapter.ts` as if the file exists,
   but it's deferred to the immediate F1 follow-up PR. Reworded as
   "the immediate follow-up PR will land a serve-side adapter" so
   reviewers don't grep for a non-existent file.

3. `bridgeOptions.ts` `fileSystem` field JSDoc had the same wording
   issue ("Production `qwen serve` wires this to..."). Same fix — now
   says "The immediate F1 follow-up will land a serve-side adapter"
   so the deferred state is obvious.

Declined from this review round:

- Copilot inline #1 (`spawnChannel.ts:155` stderr forwarder drops
  empty lines): pre-existing behavior since #3889. F1 lifted verbatim
  — not a regression introduced here. Out of scope for a lift PR.
- github-actions bot summary: most items are pre-existing notes

  positive — the file is 97 LOC after F1. Others are cosmetic

* docs(acp-bridge): tighten BridgeFileSystem contract + re-export type from shim

Self-review + code-reviewer agent fold-in, two changes:

1. `cli/src/serve/httpAcpBridge.ts` shim now re-exports
   `BridgeFileSystem` from `@qwen-code/acp-bridge/bridgeFileSystem`
   so the immediate F1 follow-up adapter (in `cli/src/serve/`)
   can import it via the established `./httpAcpBridge.js` path
   like every other daemon-side bridge import does. Without this
   the adapter would need to deep-import from acp-bridge while
   every other serve file goes through the shim — inconsistent.

2. `BridgeFileSystem.readText` + `writeText` JSDoc now spells out
   the two defensive gates the inline proxy carried (non-regular-
   file rejection + 100 MiB buffered-size cap for reads;
   write-then-rename atomicity + dangling-symlink walk-through +
   mode preservation + `0o600` new-file default for writes). When
   a `BridgeFileSystem` is injected, the inline path is FULLY
   bypassed — without the contract spelled out, a future adapter
   author could silently drop the `/dev/zero` / 500 MB log RSS
   defenses the inline path established.

Note on F1 CI: this PR targets `daemon_mode_b_main` but the
`.github/workflows/ci.yml` `pull_request` trigger is scoped to
`branches: main / release/**`, so the main CI workflow (Lint /
Test on Linux/macOS/Windows / CodeQL) does NOT run on this PR.
This is a by-design side effect of the new feature-cohesive

will trigger the full CI matrix, providing safety net coverage
before any F-series work lands on `main`. Locally verified:

* test(acp-bridge): cover BridgeFileSystem injection seam + extract shared writeStderrLine (#4319 wenshao review)

Folds in wenshao review on #4319:

1. **[Critical]** zero test coverage for the F1 step 5 `BridgeFileSystem`
   delegation branches in `BridgeClient.writeTextFile` /
   `BridgeClient.readTextFile` and the factory's
   `opts.fileSystem` → constructor positional-arg forwarding.

   New `packages/acp-bridge/src/bridgeClient.test.ts` adds 6 tests
   covering:
   - writeTextFile delegates to injected fileSystem.writeText (inline
     proxy fully bypassed; `fakeFs.writeText` called with the original
     params; `readText` mock not invoked)
   - writeTextFile invalid-path call succeeds purely via the mock
     when fileSystem is injected (proof that the inline `fs.realpath`
     path doesn't run)
   - readTextFile delegates to injected fileSystem.readText
   - readTextFile propagates injection errors to the caller
   - inline-fallback regression guard: write actually hits disk via
     the inline proxy when fileSystem is omitted (real tmp file
     round-trip)
   - same for read

   Why these matter: the 7-arg `BridgeClient` constructor places
   `fileSystem` at the tail as optional. A reordering — or dropping
   the arg from `bridge.ts` factory's `new BridgeClient(..., opts.fileSystem)`
   call — would silently bypass the adapter in production and the
   inline `fs.writeFile` raw-path would run with no audit / trust /
   TOCTOU coverage. The delegation tests would catch that because
   the mock fileSystem would never be invoked.

2. **[Suggestion]** `writeStderrLine` was defined identically in
   `bridge.ts:117` and `bridgeClient.ts:30` (22 call sites across the
   two files). Both consumers live in the SAME `@qwen-code/acp-bridge`
   package, so the original "no reverse-dep on cli" justification
   doesn't apply within the package. Extracted to
   `packages/acp-bridge/src/internal/stderrLine.ts` — a single source
   of truth that future behavior changes (timestamp prefix, log
   level, structured field) can edit once. `internal/` subpath is
   intentionally not in `package.json`'s `exports`, keeping the
   helper package-private. `spawnChannel.ts` deliberately does NOT
   consume it (its stderr writes use `process.stderr.write(prefix +
   line + '\n')` directly because each line carries its own
   `[serve pid=… cwd=…]` line prefix).

* test(acp-bridge): cover defaultSpawnChannelFactory env scrubbing + fix bridge.ts comment refs (#4319 wenshao round 2)

Folds in wenshao review on #4319 round 2 — 1 Critical + 2 Suggestions:

1. **[Critical] spawnChannel.ts has 0 unit tests, security-critical
   paths untested.** Now that `defaultSpawnChannelFactory` is a public
   export of `@qwen-code/acp-bridge`, channels + IDE consumers can't
   rely on cli-package integration tests for env-scrubbing guarantees.

   Refactored the inline env-scrubbing logic into a pure exported
   helper `scrubChildEnv(source, scrubbed, overrides)`. Behavior is
   byte-identical to the pre-extraction inline implementation; the
   factory body now reads:

       const childEnv = scrubChildEnv(
         process.env, SCRUBBED_CHILD_ENV_KEYS, childEnvOverrides);

   Added `packages/acp-bridge/src/spawnChannel.test.ts` with 12 tests
   covering:
   - shallow-clone (no aliasing into live process.env)
   - QWEN_SERVER_TOKEN stripping
   - non-scrubbed vars pass through
   - override-add a new key
   - override-replace an existing key
   - override with undefined deletes the key (PR 14 fix #4247 wenshao R5)
   - override CANNOT re-introduce a scrubbed key (defense in depth)
   - override CANNOT undo the scrub by setting undefined for a scrubbed key
   - override-apply-after-scrub ordering invariant
   - empty overrides equals no overrides
   - multi-key scrub for forward-compat (the WARNING comment on
     SCRUBBED_CHILD_ENV_KEYS anticipates a future sandboxed-agent
     mode expanding the denylist; this verifies the loop already
     handles that)

   The killChild SIGTERM→SIGKILL escalation + STDERR_LINE_CAP_CHARS
   truncation are NOT covered yet — they require either real child
   processes or extensive node:child_process mocking; both are
   orthogonal to the env-scrubbing security guarantees wenshao
   explicitly called out, and can land as a follow-up if anyone
   wants the full surface tested.

2. **[Suggestion] bridge.ts comments referenced a "consolidated re-
   export block earlier in this file" that doesn't exist in acp-bridge
   (only in the cli shim).** Fixed both occurrences (~line 292, ~line
   310) to point at the actual local import + the package barrel
   re-export.

3. **[Suggestion] bridge.ts canonicalizeWorkspace re-export comment

* docs(acp-bridge): fix 14-arg→7-arg typo in test docstring + simplify canonicalizeWorkspace re-export doc (#4319 wenshao round 3)

Folds in 2 of 3 wenshao Suggestions from #4319 round 3:

1. `bridgeClient.test.ts:20` JSDoc said "the 14-arg constructor's
   positional slot" — typo I introduced when writing the test in
   `fbc92bccf`. The same docstring correctly says "the constructor
   takes 7 positional args" at line 25. Updated to "7-arg".

2. `bridge.ts:3461` `canonicalizeWorkspace` re-export JSDoc no longer
   references the historical `cli/src/serve/fs/paths.ts` location.
   Reads cleaner as a present-tense pointer to `./workspacePaths.ts`
   (where the implementation actually lives now post-PR 22b/1).
   Git history covers the lift chain; the docstring should describe
   current state.

DECLINED + tracked separately:

- **[Critical]** `closeSession` + `killSession` use module-scoped
  `channelInfo` instead of `channelInfoForEntry(entry)` — channel-
  overlap edge case can kill the wrong channel. Wenshao explicitly
  notes "pre-existing bug preserved by the lift" — F1's mechanical-
  lift scope shouldn't carry behavior fixes, and the fix needs a
  channel-overlap regression test to land safely. Tracked as #4325.

* docs(acp-bridge): polish from second-pass self-review (cross-platform test + package metadata + dead tombstones)

Five small adoptions from a second-pass code-reviewer agent review on
F1 (no new external comments — pre-emptive cleanup before reviewer
returns):

1. **`bridge.ts:290-313`** — deleted two standalone "InvalidPermission
   OptionError / WorkspaceInit* / McpServer* lifted to bridgeErrors"
   tombstone comments. Pre-22b they were load-bearing (explained why
   the class wasn't `class`-defined inline at that file location).
   Post-F1 the symbols are imported at the top of the file and the
   comments sit between unrelated code (`writeServeDebugLine` /
   `MAX_DISPLAY_NAME_LENGTH` / `DEFAULT_INIT_TIMEOUT_MS`) with no
   anchor. Dead doc — removed.

2. **`README.md`** — `spawnChannel` entry now lists `scrubChildEnv`
   alongside `defaultSpawnChannelFactory` + `killChild` +
   `SCRUBBED_CHILD_ENV_KEYS`. Channels / VSCode IDE consume the
   package barrel so the helper should be visible in the inventory.

3. **`package.json:description`** — refreshed from the PR 22a wording
   ("EventBus, AcpChannel, in-memory channel, PermissionMediator
   interface") to include F1 additions (`createHttpAcpBridge` /
   `BridgeClient` / `defaultSpawnChannelFactory` / `BridgeFileSystem`).
   Visible on `npm view`-style tooling + IDE hover so worth keeping
   current.

4. **`bridgeClient.test.ts:92-115`** — swapped `/proc/no-such-file`
   for `/this/dir/never/exists/file.txt` and reworded the comment.
   `/proc/` is Linux-only; on macOS / Windows the inline proxy's
   dangling-symlink fallback would write through to a path under
   root rather than failing. Test passed regardless (mock assertion,
   not real disk) but the comment overstated portability.

5. **`spawnChannel.test.ts:36`** — added a comment block explaining
   why the test deliberately hand-rolls the SCRUBBED set instead of
   importing the production `SCRUBBED_CHILD_ENV_KEYS`. The
   decoupling is intentional (pure-function parameterized test +
   forward-guard for future denylist expansion) but a naive reader
   would think it's an oversight.

* fix(acp-bridge): bridge.ts security fold-in from #4297 review (3 issues)

Folds 3 unresolved review comments from the post-merge thread on #4297
(wenshao via qwen-latest agent) into F1 (#4319). All 3 touch
`acp-bridge/src/bridge.ts` — the same file F1 already moves the lifted
factory into — so consolidating here saves opening a separate
follow-up PR and keeps the security narrative in one reviewable
commit. The 2 cross-package fixes (`core/src/memory/const.ts` test
gap + `cli/src/serve/runQwenServe.ts` malformed-context fallback)
will land as their own small PRs after F1 merges.

#### Fix 1 (wenshao Critical, #4297 thread): `fs.unlink(target)`
arbitrary-file-deletion primitive in `verifyParentWithinWorkspace`
'create'-cleanup

After `fs.open(target, 'wx')` creates the empty file at the real
parent, an attacker with local workspace write access can swap the
parent directory for a symlink (`docs/` → `/etc`). The cleanup's
`fs.unlink(target)` re-resolves the TEXTUAL path through the
attacker's freshly-planted parent symlink, deleting whatever file
exists at the external location.

Fix: drop the `fs.unlink(target)` line. The 0-byte file at the
pre-race location is harmless (0 bytes, inside the workspace we'd
already verified) — leaving it over deleting an arbitrary external
file is the right safety trade. Comment block explains the
reasoning so future maintainers don't re-introduce the unlink.

#### Fix 2 (wenshao Critical): `O_TRUNC` arbitrary-file-truncation
primitive in workspace-init 'overwrite' branch

`O_TRUNC` causes the kernel to truncate the file to zero bytes AT
`open(2)` SYSCALL TIME — strictly before `verifyParentWithinWorkspace`
runs. A parent-symlink TOCTOU race between
`canonicalizeExistingAncestor` and this `open()` zeros the file at
the attacker-redirected location (arbitrary-file-truncation
primitive against any file the daemon UID can open). The pre-fix
code's own comment on `verifyParentWithinWorkspace` acknowledged
this as "Acceptable residual posture for the Stage-1 trust model";
wenshao pushed back that arbitrary-file-zeroing exceeds the
Stage-1 trust budget.

Fix: drop `O_TRUNC` from the open flags. Truncation moves to AFTER
`verifyParentWithinWorkspace` succeeds, via `fh.truncate(0)` on the
fd we already hold. fd-based truncate does NOT re-resolve the path
— an attacker swapping the parent symlink after we open can't
redirect the truncation.

#### Fix 3 (wenshao Suggestion): `canonicalizeExistingAncestor`
missing `ELOOP` catch

Circular symlinks in the parent path (`a -> b`, `b -> a`) cause
`fs.realpath` to fail with `ELOOP`. Without catching it, the error
propagates as an unstructured HTTP 500 instead of the typed
`WorkspaceInitSymlinkError` (HTTP 400) the route handler expects
from the workspace-init race-detection family.

Fix: add `'ELOOP'` to the caught error codes alongside `'ENOENT'`
and `'ENOTDIR'`. Walking up the parent chain when ELOOP hits at a
sub-component preserves the existing "walk to the deepest extant
ancestor" contract — the deepest realpath-able ancestor still
dictates the canonical prefix.

#### Why no new tests in this commit

- Fix 1 is a single-line removal: any regression that re-adds the
  unlink would be caught by reviewing the diff; existing 174-test
  `httpAcpBridge.test.ts` integration suite confirms the create-path
  still works (file is created + closed correctly; only the
  attacker-cleanup branch changes).
- Fix 2 is a structural move (truncate from open-time to post-verify);
  the existing overwrite-init integration tests confirm the
  end-to-end behavior is unchanged (file ends up empty after init).
  Adding a TOCTOU race regression test requires controlled
  filesystem-race simulation that exceeds reasonable test infra
  scope for this PR.
- Fix 3 is a one-word addition to an error code list; the
  `canonicalizeExistingAncestor` helper is module-private and the
  integration test for circular-symlink → typed 400 would require
  exporting it OR setting up a real circular-symlink workspace.
  Both routes widen scope beyond the security fix itself; the
  high-level behavior is verifiable by the existing route-error-
  mapping test pattern + diff review.

A follow-up PR can add the integration tests once the security fix
itself has shipped; the immediate priority is closing the
arbitrary-file-deletion + arbitrary-file-truncation primitives.

* fix: post-merge Codex P2 fold-in — MCP restart disabled-tools normalization + SDK timeout headroom (#4319)

Folds in 2 P2 findings from a Codex review run on `git diff main...HEAD`
of F1 PR #4319. Both are pre-existing in code merged into
`daemon_mode_b_main` before F1 was created (#4282 PR 17), but they're
tiny tactical fixes (~25 LOC + 1 LOC) on the same integration branch
the same reviewer (wenshao) already engages with, so folding into F1
saves an extra follow-up PR cycle.

#### Fix 1: normalize disabled tool names during MCP restart refresh

`packages/cli/src/acp-integration/acpAgent.ts:1563-1566`

The bootstrap path in `cli/src/config/config.ts:1426-1434` applies a
4-step normalization to `tools.disabled`:
  1. typeof string filter
  2. .trim()
  3. drop empty after trim
  4. dedupe via Set

The MCP-restart refresh path only did step 1, then stored the raw
strings. `ToolRegistry` checks disabled tools with EXACT
`Set.has(tool.name)`, so a tool disabled at boot as `' Foo '` (or
`'Foo\n'`) is no longer matched after `restartMcpServer` and gets
silently re-registered. This contradicts the documented "toggle +
restart" workflow that #4282 PR 17 advertised.

Fix: mirror the bootstrap normalization verbatim before
`setDisabledTools`. Adds 6 lines + a 7-line comment pointing at the
bootstrap reference for future maintainers.

#### Fix 2: add headroom to MCP restart SDK timeout

`packages/sdk-typescript/src/daemon/DaemonClient.ts:102`

The SDK's `MCP_RESTART_DEFAULT_TIMEOUT_MS` was EXACTLY 300_000ms, the
same ceiling the daemon's own `MCP_RESTART_TIMEOUT_MS` uses for the
upper bound on a single MCP rediscovery. For restarts that finish
(or fail with a typed `McpServerRestartFailedError` JSON envelope)
near 300s, the client `AbortSignal` could fire BEFORE the daemon had
finished serializing + transmitting the response, yielding a client
`TimeoutError` even though the daemon was still within its own
budget.

Fix: bump to 330_000ms (10% / 30s headroom over the daemon ceiling).
Comment updated to call out the race + the rationale for the
specific headroom value. Callers needing tighter caps still pass
their own `timeoutMs` to `restartMcpServer`.

#### Why folded into F1 vs separate follow-up PRs

These are post-merge findings on `#4282 PR 17` code, not F1-introduced
regressions. Normally we'd track as separate follow-up issues (mirror
of the #4325 / `channelInfo` decline). But:

- Both fixes are TINY (~25 LOC + ~2 LOC including comment); the bridge
  security fold-in commit `7bd66c6e8` set the precedent of folding in
  small same-branch issues when the cost-benefit favors closing them
  immediately.
- Same reviewer (wenshao via qwen-latest agent) — won't be confused
  by the scope expansion; in fact the original PR 17 commenter is
  also the one who'd review the follow-up issue's fix.
- Both fixes target `daemon_mode_b_main`-only paths (MCP restart route
  added by PR 17 lives on the integration branch).
- Saves opening 2 trivial follow-up issues that would just sit until
  someone picks them up.

#### Verification

- sdk-typescript: 424/424 tests pass (no test hardcoded the old
  300_000 default — only the constant declaration itself referenced it)
- cli acp-integration: 282/282 tests pass (no test exercised the
  exact whitespace-bearing disabled-tools scenario, so no test
  changes were strictly required; a regression test would belong in
  a separate test-coverage PR alongside the const.ts test gap from
  the #4297 unresolved-comment thread)
- typecheck clean across cli + sdk-typescript

* feat(daemon): server-pushed followup_suggestion event for the webui (#4507)

* feat(sdk): add followup_suggestion daemon event type

Schema-only addition that lets the daemon push server-generated
follow-up suggestions ("what you might want to ask next") through the
per-session SSE bus. Zero runtime effect on its own — old daemons
just don't emit the event, and this commit doesn't change any
publisher; the bridge handler + ACP-child generator land in follow-up
commits.

Adds the new event taxonomy across the three layers:
- `events.ts`: `followup_suggestion` in `DAEMON_KNOWN_EVENT_TYPE_VALUES`,
  `DaemonFollowupSuggestionData` interface, `DaemonFollowupSuggestionEvent`
  envelope, `DaemonAssistEvent` union (new — reserved for future assist
  hints like server-side speculation), `KnownDaemonEvent` extension,
  `lastFollowupSuggestion` on `DaemonSessionViewState`,
  `asKnownDaemonEvent` + `reduceDaemonSessionEvent` cases, and an
  `isFollowupSuggestionData` predicate rejecting empty / malformed
  payloads.
- `ui/normalizer.ts` + `ui/types.ts`: maps the daemon event to a
  typed `DaemonUiFollowupSuggestionEvent` (`type: 'followup.suggestion'`).
- `ui/transcript.ts` + `ui/store.ts`: stores `lastFollowupSuggestion` on
  `DaemonTranscriptSidechannelState` (no chat-stream block), exposes a
  `selectLastFollowupSuggestion` selector, and adds a
  `clearFollowupSuggestion()` store action mirroring `clearAwaitingResync`
  so adapters can invalidate the suggestion on sendPrompt without a
  wire round-trip.
- `ui/terminal.ts`: adds the new variant to the exhaustive switch so the
  terminal renderer stays exhaustive.
- Public surface re-exports in `daemon/index.ts`, `daemon/ui/index.ts`,
  and top-level `src/index.ts`.

Tests:
- `daemonEvents.test.ts` covers schema narrowing, malformed/empty-string
  rejection via `unrecognizedKnownEventCount`, and reducer overwrite
  semantics.
- `daemonUi.test.ts` covers normalizer happy path + malformed fallback,
  transcript sidechannel storage (no block append), the
  `clearFollowupSuggestion` store action, and the terminal renderer
  line.

Wire contract is additive: old SDK consumers ignore unknown
`followup_suggestion` events via `asKnownDaemonEvent → undefined`.

* feat(acp-bridge): publish followup_suggestion from extNotification

Recognize a new ACP child→bridge notification method
`qwen/notify/session/prompt-suggestion` and translate it into a
`followup_suggestion` SSE frame on the per-session bus. Mirrors the
existing `qwen/notify/session/mcp-budget-event` precedent in the same
handler.

Differences from `mcp-budget-event`:
- No early-event buffering: the new method only fires *after* a
  prompt completes, never inside `newSession`. A missing entry means
  the session has already closed, in which case we drop the
  suggestion silently (best-effort UX).
- The wire `data` is the same shape as the inbound `params` minus
  `v`; no `kind` discriminator (the method name is the
  discriminator), so the routing logic is straight-line.

Empty or malformed payloads (missing sessionId / suggestion / promptId,
non-string fields, empty suggestion) are dropped at the handler
boundary — the daemon filters rejected suggestions server-side via
`getFilterReason()` and only emits when accepted, so empty strings on
the wire are protocol garbage and not worth a debug fallback.

The frame stamps `originatorClientId` from `activePromptOriginatorClientId`
when one is set (same pattern as `mcp-budget-event`).

Tests:
- Happy path: notification arrives, SSE frame fires with full payload
  and monotonic id.
- Malformed-payload drops (missing fields / empty suggestion / wrong
  types) produce no SSE frame.
- Post-close notification drops silently without throwing (no early
  buffering means no resurrection of dead sessions).

* feat(daemon+webui): generate and surface followup suggestions per turn

The activating change for the daemon follow-up suggestion pipeline.
Wires together the SDK schema (Commit 1) and the bridge handler
(Commit 2) so the daemon actually generates and pushes a server-side
suggestion after every clean assistant turn, and provides the webui
hook that consumes it.

## ACP child (Session.ts)

Adds a fire-and-forget IIFE at the end of `prompt()` (after
`#executePrompt` resolves with `stopReason === 'end_turn'`) that:

- Calls the existing `generatePromptSuggestion` from core with the
  curated, 40-entry-tail conversation history (same shape as the
  CLI's `AppContainer.tsx` integration).
- Forwards the result through the new
  `qwen/notify/session/prompt-suggestion` extNotification when a
  non-empty post-filter suggestion is produced.
- Logs filter-reason suppressions via the existing
  `PromptSuggestionEvent` telemetry — keeps generator analytics
  observable in the same stream regardless of in-process vs daemon
  execution.

Guards mirror the CLI's path: only on `end_turn`, only when
`settings.merged.ui.enableFollowupSuggestions === true`, and never in
`ApprovalMode.PLAN`. The IIFE swallows its own errors — a failed
suggestion is invisible UX, and a throw here would propagate up
through `prompt()` and break the primary response path.

A new `followupAbort: AbortController | null` field is aborted at
the top of the next `prompt()` and inside `cancelPendingPrompt()`, so
a stale suggestion never lands after the user has moved on.

Tests cover: happy path (extNotification fires with the right
payload), feature disabled (no call), PLAN mode (no call),
suppressed result logs PromptSuggestionEvent, new prompt aborts
in-flight gen, cancelPendingPrompt aborts in-flight gen. The tests
use a partial `vi.mock` of `@qwen-code/qwen-code-core` to spy on
`generatePromptSuggestion` / `logPromptSuggestion` while preserving
the rest of the core surface for existing tests.

## Webui hook (useDaemonFollowupSuggestion)

A small hook that subscribes to the SDK store's
`lastFollowupSuggestion` sidechannel and drives the existing
`useFollowupSuggestions` controller. Returns `{ followupState,
onAcceptFollowup, onDismissFollowup, clear }` ready to wire into
`<InputForm followupState={...} ... />`.

Promo `lastPushedPromptIdRef` is what prevents the effect from
re-showing a suggestion after the user dismisses it locally — without
the gate, the React effect would see the still-present store value on
the next render and replay it.

Both accept and dismiss callbacks also clear the store via
`store.clearFollowupSuggestion()`, and `clear()` is exposed for
adapters to call just before `actions.sendPrompt(...)` so the prior
turn's ghost-text disappears immediately (no wire round-trip — the
daemon does not emit a "cleared" event on prompt boundaries; clients
self-invalidate).

## Sidechannel perf tweak (transcript.ts)

`cloneTranscriptState` now shares the `lastFollowupSuggestion`
reference between snapshots (the reducer assigns a new object when
updating, never mutates in-place). Reference stability across unrelated
dispatches lets `useSyncExternalStore` subscribers skip re-renders for
events that don't touch the suggestion — without this, the hook would
re-render once per assistant text delta in a streaming turn.

## Notes

- The webui package lacks an automated test runner in this repo
  (no `test` script in `package.json`, not in root `vitest.config.ts`
  `projects`). The hook is exercised end-to-end via the daemon
  integration but has no dedicated unit-test file in this PR; that's
  separate scaffolding work.

* fix(serve): post-merge fixes for #4291 review (7 threads) (#4305)

* fix(serve): address qwen-latest review on merged #4291 (7 threads)

Seven post-merge findings from the qwen-latest review on #4291,
all real. Most are tightening fixes for issues introduced by the
earlier rounds of #4291 — the same security / DRY / observability
classes the original review surfaced, applied to surfaces that
weren't covered initially.

#1 (deviceFlow.ts:1179) — late-poll observer closure retained the
entire entry by reference (deviceCode/pkceVerifier BrandedSecrets +
cancelController) for the lifetime of the daemon if `provider.poll()`
never settled. Memory leak + indefinite secret retention. Destructure
the four fields the closure actually needs (deviceFlowId, providerId,
initiatorClientId, audit sink) so the entry is GC-eligible the
moment runPollTick returns.

#2 (server.ts) — `callerIsInitiator` was duplicated verbatim across
three locations: GET handler, toDeviceFlowStartResponseBody,
toDeviceFlowStateBody. The exact bug class #4291 was fixing was
"POST and GET diverged on the same redaction policy" — duplicating
the gate recreated the preconditions for divergence. Extracted to
shared `callerIsDeviceFlowInitiator(view, callerClientId)` helper
with the consolidated threat-model JSDoc. All three sites now call
the helper.

#3 (deviceFlow.ts:1110) — timeout callback constructed two separate
`DeviceFlowPollTimeoutError` instances (one for `signal.reason`, one
for the wrapper rejection). Each capture its own V8 stack trace,
and `signal.reason.stack` would diverge from the caught rejection's
stack — confusing for operators inspecting both. Build the sentinel
ONCE per timer fire and pass the same instance to both sites.

#4 (qwenDeviceFlowProvider.ts:273) — `Error.name` is a freely
assignable string property; a hostile fetch wrapper could set
`e.name = 'X\n[serve] FAKE LINE\x1b[31m'` to inject log lines or
ANSI sequences via the same vector we already closed for `oauthError`.
The non-OAuth catch path interpolated `${err.name}` raw. Apply the
same `sanitizeForStderr()` helper.

#5 (deviceFlow.ts:1551) — on the timeout path, `rawProviderError`
is undefined (deliberately, to skip the misleading
`provider.poll() threw (raw): ...` audit template), but that left
the audit hint field omitted entirely. Operators reading the
durable audit trail saw `errorKind: 'upstream_error'` with no signal
whether it was a hung IdP or a generic provider failure. Use
`result.hint` (which already carries the timeout-specific
`provider.poll() timed out after Nms; check IdP connectivity` text
built in the catch) so the audit matches the SSE event.

#6 (server.ts) — the `QWEN_SERVE_DEBUG` env-var check was inlined
in the GET route handler, duplicating the `isServeDebugMode()`
helper from `./debugMode.js` that workspaceAgents and
workspaceMemory already use. The inline copy also had a dead `?? ''`
fallback (the value is guaranteed truthy at that point per the
preceding check). Use the canonical helper.

#7 (deviceFlow.ts:1217) — late-rejection observer interpolated the
raw `lateErr.message` into the audit hint (truncated to 256 bytes,
but RFC 8628 `device_code` values fit comfortably in 256 bytes).
The provider's catch already uses the `name + length` redaction
pattern to prevent WAF-echoed `device_code`/PKCE leaks; the
registry layer was undoing that hardening because the same failure
settled late. Apply the same `name + length` pattern at the late-
rejection site.

Tests:
- Existing late-rejection test reseeded with a `device-code-secret-*`
  substring inside the long detail; hard-negative-asserts the seeded
  secret is absent from the audit + asserts the new
  `Error (message N bytes; raw suppressed)` shape.
- Existing poll-timeout test now also asserts: hint IS defined on
  the audit (not omitted), hint contains `'timed out after'` /
  `'check IdP connectivity'`, and `signal.reason instanceof

* fix(serve): address deepseek-v4-pro review on #4305 (4 threads)

Round-5 fold-in. Four findings from the deepseek-v4-pro review on
PR #4305 — all real, three are sister fixes for the same security
classes that #4305 already closed at adjacent surfaces.

#1 (deviceFlow.ts) — `pollTimedOut` race correctness. The flag was
set unconditionally inside the timer callback. If the provider
settled the wrapper at 29.9s, `finally` would call
`clearScheduled(pollTimer)` — but if the timer callback was already
queued for execution before the clear landed (a real possibility
in Node's event-loop ordering, even if not always observed in
practice), this branch could still run and incorrectly mark
`pollTimedOut`. Move the flag assignment to the catch block where
the settled cause is unambiguous via `instanceof
DeviceFlowPollTimeoutError`. New test pins the negative: provider
beats the timeout → no spurious `lost_late_poll_after_timeout`
audit even after ticking 2× the ceiling.

#2 (deviceFlow.ts) — late-rejection observer interpolated raw
`lateErr.name` into the audit hint without sanitization. Same
attacker-controlled vector closed at the provider layer for
`err.name` in round-4. Route through `sanitizeForStderr`.

#3 (deviceFlow.ts) — late-success observer interpolated
`latePollResult.kind` directly into the audit template. While the
typed shape is `'pending' | 'slow_down' | 'success' | 'error'`, a
non-conforming provider could return an arbitrary string. Same
log-injection vector. Route through `sanitizeForStderr`.

#4 (qwenDeviceFlowProvider.ts → deviceFlow.ts) —
`sanitizeForStderr` only stripped ASCII C0/C1 + DEL; bypass via
Unicode lookalikes:
  - U+2028/U+2029: LINE/PARAGRAPH SEPARATOR (newline-equivalent in
    most Unicode-aware terminals — most direct log-forging vector)
  - U+200B–U+200F: zero-width chars + LRM/RLM
  - U+202A–U+202E: bidirectional override controls
  - U+FEFF: BOM / ZWNBSP

A malicious IdP returning `slow_down
[serve] FAKE` in
`oauthError` would otherwise still forge log lines.

Architectural change: `sanitizeForStderr` was previously private to
`qwenDeviceFlowProvider.ts`. To address #2/#3, the registry layer
needs to call it too. Lifted into `deviceFlow.ts` (the foundation
module) and re-imported from the provider. Single source of truth;
the regex is now a module-level constant compiled once with explicit
`\uXXXX` escapes (via `String.raw` so the source is greppable, not
literal-Unicode-laden).

Tests:
- `does NOT attach late-poll observer when the provider beats the
  timeout` — N1 race regression
- `sanitizes hostile latePollResult.kind in late-observer audit` — N3
- `sanitizes hostile lateErr.name in late-rejection observer audit` — N2
- `sanitizes Unicode lookalike controls (U+2028 LINE SEPARATOR,
  bidi, ZWNBSP) in oauthError` — N4

* fix(serve): address gpt-5.5 + qwen-latest review on #4305 round-5 (5 threads)

Round-6 fold-in. Five findings split between maintainability,
security hardening, and a real defensive bug.

#1 (qwenDeviceFlowProvider.test.ts) — gpt-5.5: round-5 #4 test
embedded U+2028 / U+200E / U+FEFF as literal characters in source.
Invisible in GitHub diffs / most editors; the negative
`not.toContain('')` looked like an empty-string check. Rewrote
the payload + assertions to use named `\uXXXX`-bound constants.
Also added a companion test exercising U+2066–U+2069 (round-6 #5
below).

#2 (deviceFlow.ts) — qwen-latest: the late-poll observer's
`void tracked.then(...)` was missing a terminal `.catch(() => {})`.
A synchronous throw inside either handler (e.g., a misbehaving
`audit.record`: backpressure, malformed payload, sink out-of-disk)
would reject the derived promise unhandled. On Node 22's default
`--unhandled-rejections=throw`, that crashes the daemon. Added the
terminal `.catch(() => {})` matching the persist-tracker pattern.
New test injects a poison audit sink that throws specifically on
the `lost_late_poll_after_timeout` call; asserts `flushAsync()`
resolves cleanly.

#3 (deviceFlow.ts) — qwen-latest: the `case 'error'` audit-record
hint interpolated `rawProviderError` (raw `err.message`) without
`sanitizeForStderr`. Per ES2019+ `JSON.stringify` no longer escapes
U+2028/U+2029 — those would still forge log lines downstream
through file/stdout audit sinks. Apply the same sanitizer used on
every other provider-controlled audit path. New test pins a hostile
provider message containing U+2028 + ANSI escape and asserts
neither survives.

#4 (deviceFlow.ts) — qwen-latest: the round-5 #1 comment claimed
"`DeviceFlowPollTimeoutError` isn't exported as a public DeviceFlow
contract", but it IS `export class` (the test file constructs it
directly for fixtures). With `pollTimedOut = true` keyed solely on
`instanceof`, a future provider that imports + throws the class
would spoof the registry's "I caused the timeout" signal —
attaching a phantom late-poll observer.

Fix: introduce a runtime brand `_isRegistryTimeout: boolean` on the
class (default `false`) plus an internal-only
`makeRegistryPollTimeoutError(ms)` helper that sets the brand to
`true`. The brand is set ONLY at the registry's race-timer
construction site. Both gates updated:
  - `if (err instanceof X && err._isRegistryTimeout === true)` in
    the catch (for `pollTimedOut`)
  - `if (lateErr instanceof X && lateErr._isRegistryTimeout === true)`
    in the late-rejection self-filter

A provider-thrown brand-false instance now flows through the
generic provider-throw audit path — correctly auditing the misuse
rather than silently swallowing it. Repurposed the original "no
double-audit when registry's own DeviceFlowPollTimeoutError is
late-rejected" test (which was actually exercising the brand-false
path) into the inverted assertion: brand-false provider throw IS
audited as a real failure. Removed the orphaned old assertion; the
brand-true happy path is implicitly covered by the hanging-provider
test (which exercises the registry-built timeout end-to-end).

#5 (deviceFlow.ts) — qwen-latest: `sanitizeForStderr` regex covered
U+202A–U+202E (bidi embedding/override) but missed U+2066–U+2069
(LRI/RLI/FSI/PDI). These are the primary CVE-2021-42574
("Trojan Source") attack vectors — a hostile IdP swapping U+2066
for U+202D achieves the same visual reordering and would have
bypassed the round-5 filter entirely. Extended the regex range and
JSDoc; new test exercises U+2066/U+2068/U+2069 in `oauthError` and
asserts none survive while substantive ASCII parts remain.

* fix(serve): post-merge P2 corrections from Codex review on #4282

Follow-up to PR #4282 (Wave 4 PR 17) addressing four P2 issues
flagged by Codex's `/review` after the squash-merge to main:

P2-1 — Read the workspace context filename for init
  `qwen serve` parent never goes through `loadCliConfig`, so the
  process-global `getCurrentGeminiMdFilename()` stays on the default
  `QWEN.md` even when the workspace configures
  `context.fileName: 'AGENTS.md'`. `runQwenServe` now snapshots the
  workspace's merged setting at boot and forwards via
  `BridgeOptions.contextFilename`, so init writes the same file the
  ACP child reads.

P2-2 — Restart MCP servers with a fresh disabledTools snapshot
  `Config.disabledTools` was frozen at construction time;
  `setWorkspaceToolEnabled` only updated settings.json. The
  documented "toggle + restart" workflow re-registered just-disabled
  tools because rediscovery still saw the bootstrap snapshot. Added
  `Config.setDisabledTools()` plus a re-read at the ACP restart
  handler so `discoverMcpToolsForServer` honors the latest set.

P2-3 — Match the SDK timeout to the daemon's restart budget
  Bridge waits up to 300s for stdio MCP discovery; SDK helper used
  the client-wide 30s default and aborted valid slow restarts.
  Added a per-call `timeoutMs` plumbed through `fetchWithTimeout`,
  defaulting `restartMcpServer` to 5 minutes.

P2-4 — Reject symlinked parent directories before init writes
  `lstat(target)` only checked the final component; a symlinked
  parent (e.g. `docs -> /tmp` with `context.fileName:
  'docs/QWEN.md'`) would let `writeFile` follow the link and create
  / truncate outside `boundWorkspace`. Added
  `canonicalizeExistingAncestor` (walks up through ENOENT to the
  deepest extant ancestor, then `realpath`s) and verifies the
  canonical parent stays within the canonical workspace.

5 new tests (4 bridge / 2 SDK):
- contextFilename snapshot honored
- parent-symlink escape rejected
- nested real subdir accepted
- restartMcpServer survives 1.2s response with 1s default timeout
- restartMcpServer honors a 50ms caller override

* fix(serve): fold-in 1 — address 16:32:44-round review on #4282

Follow-up addressing the 8 unresolved review threads opened on PR
shipping in this same #4297; addresses correctness gaps + missing
test coverage that would otherwise let regressions ride into main.

Behavior fix:
- broadcastWorkspaceEvent gains a `skipSessionId` parameter; when
  `setSessionApprovalMode` runs with `persist:true`, the broadcast
  skips the requesting session so it doesn't receive the same
  `approval_mode_changed` event twice (once via session-scoped
  publish + once via broadcast). The SDK reducer's
  `approvalModeChangedCount` now increments by 1, not 2, on the
  requesting client (peers still see 1 via the broadcast).
  Addresses #3260501134.

Observability + posture:
- broadcastWorkspaceEvent now mirrors PR 16's publishWorkspaceEvent
  member: per-entry success/failure accounting + an "ALL buses
  dropped" stderr elevation. The previous local helper silently
  swallowed every publish failure. Addresses #3260501126.
- WorkspaceInitPathEscapeError + WorkspaceInitSymlinkError typed
  classes for the two boundary guards in initWorkspace, mapped to
  HTTP 400 by sendBridgeError. Previous generic `Error` fell
  through to the 500 handler, telling operators "daemon broken"
  when the actual fix was workspace-config correction. Addresses
  #3260501161.

Public surface symmetry:
- Re-export McpServerNotFoundError, McpServerRestartFailedError,
  WorkspaceInitPathEscapeError, WorkspaceInitSymlinkError from the
  serve barrel. External embeds matching these via `instanceof`
  no longer need deep imports. Addresses #3260501163.

Test coverage:
- restartMcpServer bridge tests (5): success + event broadcast,
  soft-skip + refused event, McpServerNotFoundError translation,
  McpServerRestartFailedError translation, originator clientId
  stamping. Addresses #3260501141.
- sendBridgeError mapping tests (4): McpServerNotFoundError → 404,
  McpServerRestartFailedError → 502, WorkspaceInitPathEscapeError
  → 400, WorkspaceInitSymlinkError → 400. Addresses #3260501148.
- initWorkspace boundary guard tests (2 added): symlink-at-target
  rejected, contextFilename '../outside.md' rejected. Addresses
  #3260501157.
- TrustGateError tests assert the typed class via `.toThrow(TrustGateError)`,
  not just message text. Addresses #3260501165.

Also updates the existing fold-in 4 S2 broadcast test to reflect
the new no-duplicate semantics on the requesting session.

* fix(serve): fold-in 2 — copilot + wenshao review on #4297

Round-2 reviewer adoption on the same PR:

Critical fixes:
- `restartMcpServer` JSDoc documents `timeoutMs: 0` as "disable the
  timeout entirely", but the `> 0` guard in `fetchWithTimeout`
  rejected `0` and silently fell back to the 30s client default.
  Loosened the guard to `>= 0` so `0` flows through to the
  no-timeout branch via the existing truthiness check; NaN /
  negative inputs still coerce to the client default. Addresses
  duplicate reports from copilot (#3260577538) and wenshao
  (#3260661833).
- TS2322 in the slow-fetch test stub: `resolveResponse` was typed
  against `import('undici-types').Response` but assigned a
  `(v: Response) => void`. Re-typed against the global `Response`
  throughout. Caught only by tsc runs that include the test
  files. Addresses #3260663072.

Test fidelity:
- Slow-fetch stub now observes `init.signal` and rejects on abort,
  so a regression that drops the per-call `timeoutMs` override
  will reliably fail the test instead of resolving after the
  timer fired (false-negative coverage). Addresses #3260577600.
- New test pinning the `timeoutMs: 0` semantics: 1ms client
  default + a stub that resolves after 50ms. Without the `>= 0`
  fix, the call would abort at 1ms; with it, the explicit
  `0` disables the timer and the call completes.

Bug fixes:
- `runQwenServe.contextFilenameForInit` previously called
  `String(arr[0])` on the array branch, producing a literal
  `"[object Object]"` filename for hand-edited bad data. Now
  validates each element with `typeof === 'string'` and falls
  back to `undefined` (so the bridge uses its
  `getCurrentGeminiMdFilename()` default) when no string is
  found. Addresses #3260577641.

Documentation drift:
- `Config.getDisabledTools()` JSDoc rewritten to describe the
  mutable-via-`setDisabledTools()` semantics introduced by P2-2,
  and the "registration-time only / no retroactive unregister"
  contract that pairs with it. Old comment claimed the set was
  frozen at construction. Addresses #3260577677.

Observability:
- `acpAgent` MCP-restart `loadSettings` failure now surfaces a
  stderr line naming the server + the underlying error, instead
  of silently swallowing it. The documented "toggle + restart"
  workflow used to break with zero diagnostic when settings.json
  was corrupted or unreadable. Addresses #3260663303.

Code organization:
- Moved `canonicalizeExistingAncestor` after `describeStatKind` so
  the latter's JSDoc is no longer orphaned (TypeScript only
  associates the last `/** ... */` block before a declaration).
  Addresses #3260668618.

* fix(serve): fold-in 3 — read merged scope on MCP restart refresh

Critical bug from wenshao review (#3260725526) on PR #4297:
the P2-2 acpAgent re-read narrowed `Config.disabledTools` to
`SettingScope.Workspace` alone, dropping User / System scope
entries. The bootstrap Config received `merged.tools?.disabled`
(union of all scopes), so user-level / system-level disables
worked at boot — but the first `mcp restart` would replace the
in-memory set with the workspace scope alone, silently re-enabling
any tool that was disabled at a higher scope but absent from the
workspace file.

The asymmetry vs. the persist-write path is deliberate and
documented:
- Reads (here): merged — match the bootstrap Config snapshot,
  preserve user/system policy.
- Writes (`runQwenServe.persistDisabledTools`): workspace scope —
  don't bake higher-scope entries into the workspace file
  (per-#4282 fold-in 1 H2 fix).

Two paths look alike but answer different questions.

1616/1616 unit tests pass.

* fix(test): fold-in 4 — wire timeoutMs:0 stub to init.signal

Critical follow-up from wenshao (#3260810242) on PR #4297:
the new `timeoutMs: 0` regression test (added in fold-in 2)
inherited the same flaw it was meant to prevent — the slow-fetch
stub didn't observe `init.signal`, so a regression that ignored
the `0` override would fire the AbortController at the 1ms client
default but the stub would keep the promise pending. The 50ms
`resolveResponse` would win, the test would still pass, and the
documented "0 disables timeout" contract would be unprotected.

Mirrored the listener pattern already used by the two sibling
tests in fold-in 2 — `init.signal.addEventListener('abort', () =>
reject(...))`. Now a regression that re-rejects `0` triggers the
abort, the stub rejects, the test fails.

8/8 restartMcpServer SDK tests pass; SDK typecheck clean.

* fix(serve): fold-in 5 — TOCTOU + setDisabledTools coverage

Two new critical reviews from wenshao on PR #4297:

C1 — TOCTOU between lstat and writeFile (#3260836305):
The `lstat(target)` symlink check and the subsequent `writeFile`
were two separate syscalls, leaving a race window where a local
attacker with workspace write access could substitute a symlink
between them. With `force: true`, `writeFile` would follow the
link and truncate an external target.

The `action === 'created'` path now uses `fs.open(target, 'wx')`
(O_WRONLY|O_CREAT|O_EXCL), which atomically refuses any
pre-existing inode (regular file, dir, OR symlink) at the target
path. EEXIST after the absence check most plausibly means a
race-created symlink, so we throw `WorkspaceInitSymlinkError(kind:
'target')` — same typed class the route maps to 400.

The `force: true` overwrite path retains the existing TOCTOU as a
documented limitation; closing it requires `O_NOFOLLOW`-aware open
which the post-PR18 `WorkspaceFileSystem` migration will provide.

C2 — P2-2 zero test coverage (#3260836302):
The `setDisabledTools` runtime sync was the only Wave-4 P2 fix
without a dedicated test. Added 5 Config-level tests:
- Initializes from `disabledTools` ConfigParameters
- Defaults to empty set when omitted
- `setDisabledTools` replaces the live snapshot
- Defensive copy: caller-set mutations don't leak into the live snapshot
- Accepts an empty set (clears live snapshot)

Plus a TOCTOU regression test in httpAcpBridge.test.ts that
spies fs.lstat / fs.readFile to simulate the race window:
pre-creates a symlink, makes lstat lie about it, asserts the
'wx' open catches the racing inode and throws the typed
`WorkspaceInitSymlinkError(kind: 'target')`.

1622/1622 unit tests pass; typecheck clean across cli /
sdk-typescript / core.

* fix(serve): fold-in 6 — count actual skips in broadcast alarm

DeepSeek review on #4297 (#3261079572):
`broadcastWorkspaceEvent` unconditionally subtracted 1 from the
`eligible` recipient count whenever `skipSessionId` was set, even
when the id matched zero live sessions (caller mistake, stale id,
or the matching session was just torn down between resolution and
broadcast). In a single-session workspace that's the difference
between `eligible = 0` (alarm suppressed) and `eligible = 1`
(alarm fires when the publish failed) — silently losing the
all-dropped breadcrumb the telemetry was meant to surface.

Today's call sites pass real session ids so the bug doesn't
manifest in practice, but the defensive shape is small: track
`skippedCount` inside the loop and subtract that, so the alarm
condition is self-consistent regardless of how the caller mis-uses
the param.

162/162 bridge tests pass; CLI typecheck clean.

* fix(serve): fold-in 7 — close overwrite TOCTOU, harden boot + diagnostics

Round-7 review on PR #4297. Three critical fixes + one suggestion
test, plus a regression test for the overwrite TOCTOU close.

C1 — force:true overwrite TOCTOU (#3262615446):
The fold-in 5 fix only closed the `'created'` action via 'wx';
the `'overwrote'` branch still used plain `fs.writeFile`, so a
local writer could swap the verified regular file to a symlink
between the lstat/readFile checks and the write and have the
forced overwrite truncate an external target. Switched to
`fs.open(target, O_WRONLY | O_TRUNC | O_NOFOLLOW)` — `O_NOFOLLOW`
makes open() fail with ELOOP on a symlink at the final component
even under race. ELOOP / ENOENT (race-deleted) translate to
`WorkspaceInitSymlinkError(kind: 'target')` so the route still
maps to a structured 400 instead of a generic 500.

C2 — settings.json corrupt blocks daemon boot (#3262625091):
`loadSettings(boundWorkspace)` at boot had no try/catch — a
corrupted, malformed, or temporarily unreadable settings file
threw synchronously and prevented daemon startup. Pre-PR this
never happened because settings were read lazily inside request
handlers. Wrapped in try/catch with stderr fallback so the daemon
keeps booting (with the bridge's default context filename) when
the file is broken.

C3 — malformed `tools.disabled` clears policy silently (#3262625101):
When `merged.tools?.disabled` is present but not an array
(boolean / string / object from a hand-edited settings.json), the
ternary `Array.isArray(...) ? ... : []` substituted an empty list
without firing the surrounding catch block. After an MCP restart
every disabled tool would silently re-register. Added an explicit
`!Array.isArray && !== undefined` check that stderr-logs the
malformed type before clearing — operators see the
misconfiguration instead of a stealth re-enable.

S1 — contextFilename extraction tested (#3262690842):
Lifted the inline `firstStringInArray` + branching into an
exported `extractContextFilename(value: unknown)` helper and
added `runQwenServe.test.ts` with 5 tests covering the four
branches the suggestion called out: non-empty string, array with
strings, array with no strings, non-string non-array.

Plus a TOCTOU regression test for the overwrite path that
verifies `O_NOFOLLOW` returns `WorkspaceInitSymlinkError(kind:
'target')` when the file is race-substituted with a symlink
behind the lstat/readFile mocks.

S2 (acpAgent restart-handler integration test #3262690845) is
deferred — Config-level coverage of `setDisabledTools` already
locks the load-bearing surface (5 tests in fold-in 5), and
adding a full acpAgent integration test requires heavy ext-method
plumbing. The new C3 stderr diagnostic plus existing tests give
us the regression signal we need without that scaffolding.

1627/1627 unit tests pass; typecheck clean across cli /
sdk-typescript / core / acp-bridge.

* fix(serve): fold-in 8 — split ELOOP / ENOENT diagnostic in overwrite path

qwen-latest review on PR #4297 (#3262861754):
The fold-in 7 ELOOP/ENOENT branch shared one error message that
said "swapped to a symlink." That's accurate for ELOOP (genuine
O_NOFOLLOW rejection — likely an attack race) but misleading for
ENOENT in the overwrite path: there `readFile` just succeeded
proving the file existed, so ENOENT means the file was DELETED
between the content check and the open — a benign race with a
concurrent writer (git checkout, editor save, lockfile rename),
NOT a symlink swap. An operator seeing the symlink language for
a benign delete would `ls -la`, see no symlink, and waste time
hunting an attack that didn't happen.

Split into two messages:
- ELOOP: "swapped to a symlink between the content check and the
  overwrite — refusing to follow it"
- ENOENT: "deleted between the content check and the overwrite
  (likely a concurrent writer) — refusing to recreate blindly"

Both still surface as `WorkspaceInitSymlinkError(kind: 'target')`
so the route maps to a structured 400; the class doubles as the
workspace-init race-condition bucket with kind='target' meaning
"target inode misbehaved at write time" generally.

Updated the existing fold-in 7 TOCTOU test to assert the ELOOP
message specifically, and added a new ENOENT race-delete test
that mocks lstat/readFile to land on the overwrote action against
a non-existent path — verifies the message says "deleted" and
NOT "swapped to a symlink."

170/170 bridge tests pass; CLI typecheck clean.

* fix(serve): fold-in 9 — route MCP restart through registry cleanup wrapper

gpt-5.5 critical review on PR #4297 (#3263088414):

The fold-in 5 P2-2 fix refreshed `Config.disabledTools` from merged
settings, but then called `manager.discoverMcpToolsForServer()`
directly — bypassing the `ToolRegistry.discoverToolsForServer`
wrapper that PURGES the server's existing `DiscoveredMCPTool`
entries (and `revealedDeferred` markers) plus its prompts before
rediscovery. Without the cleanup, `registerTool` only consulted
the refreshed `disabledTools` set for NEWLY-discovered tools —
entries already in the registry from the prior MCP boot kept
serving requests. Net effect: toggle-disable-then-restart
silently left the disabled tool live, breaking the documented
"toggle + restart" workflow that P2-2 was meant to fix.

Routed through `toolRegistry.discoverToolsForServer(serverName)`
which:
1. Removes existing `DiscoveredMCPTool` entries for this server
2. Drops their `revealedDeferred` reveal state
3. Removes the server's prompts via `removePromptsByServer`
4. THEN delegates to `manager.discoverMcpToolsForServer` for the
   actual reconnect + rediscover

The pre-discovery budget / in-flight checks still go through the
`manager` reference (which is the same object the registry
wrapper would forward to) — so soft-skip semantics for
`budget_would_exceed`, `in_flight`, `disabled` are preserved.

CLI typecheck clean; 403/403 server + bridge tests pass.

* fix(serve): fold-in 10 — qwen-latest 05:45-round review on #4297

5 review threads from qwen-latest's late round on PR #4297 (now closed
in favor of #4313 against `daemon_mode_b_main`). 1 critical + 4
suggestions, all adopted.

C1 — extractContextFilename / getCurrentGeminiMdFilename divergence
(#3263954685): with `context.fileName: ['  ', 'AGENTS.md']`, the
daemon parent's `extractContextFilename` (which skips empty entries)
wrote `AGENTS.md`, but the ACP child's `getCurrentGeminiMdFilename`
(which returned `arr[0]` unconditionally) read `''`. The init'd file
was orphaned. Aligned `getCurrentGeminiMdFilename` to skip empty
entries with the same semantics, falling back to
`DEFAULT_CONTEXT_FILENAME` when all entries are empty.

S2 — WorkspaceInitSymlinkError reused for non-symlink races
(#3263954690): the EEXIST race-create and ENOENT race-delete cases
were surfacing as `code: 'workspace_init_symlink'`, misleading
operators into hunting symlink attacks for benign concurrent-
modification windows. Split into a sibling `WorkspaceInitRaceError`
class (`kind: 'eexist' | 'enoent'`, HTTP code
`workspace_init_race`). The genuine symlink class stays for ELOOP,
lstat-detected target symlinks, and parent-realpath escapes.

S3 — fsConstants.O_NOFOLLOW defensive `?? 0` (#3263954697): matches
the existing codebase convention in
`core/src/utils/{sessionStorageUtils,gitDiff}.ts` and
`cli/src/ui/utils/customBanner.ts`. Functionally a no-op (JS
bitwise coerces undefined to 0) but consistent.

S5 — Parent-directory TOCTOU still open (#3263954707): O_NOFOLLOW
only protects the final path component; a local writer could swap
a real parent dir for a symlink between
`canonicalizeExistingAncestor` and `fs.open`. Added
`verifyParentWithinWorkspace` post-open helper that re-realpaths
`path.dirname(target)` and refuses with
`WorkspaceInitSymlinkError(kind: 'parent')` if the parent moved.
On the create path (where we just opened with `'wx'`), the failure
also unlinks the file we just made best-effort. Residual race
window narrowed from "between pre-check and open" to "between
post-open realpath and writeFile" — sub-millisecond, documented as
accepted Stage-1 trust posture.

S4 — broadcastWorkspaceEvent vs publishWorkspaceEvent stale comment
(#3263954688): the "now removed" comment was inaccurate (5 call
sites still use the closure). Replaced with an accurate
description of why both coexist (factory closure can't `this`-call
proxy member; closure also takes `skipSessionId` for persisted
approval-mode mirror) and a TODO marker for future helper extraction.

Two existing tests updated to assert the new `WorkspaceInitRaceError`
class for EEXIST / ENOENT scenarios (the symlink-class assertions
are preserved for ELOOP / lstat / parent cases).

1759/1759 unit tests pass; typecheck clean across all 4 packages.

* feat(acp-bridge): F1 — acp-bridge package self-sufficiency (#4175 mechanical lift + BridgeFileSystem seam) (#4319)

* refactor(acp-bridge): lift defaultSpawnChannelFactory to acp-bridge/spawnChannel (#4175 F1 step 1)

First mechanical lift of #4175 F1 (acp-bridge package self-sufficiency).
Moves the production spawn factory + its `killChild` helper +
`SCRUBBED_CHILD_ENV_KEYS` denylist + `KILL_HARD_DEADLINE_MS` constant
from `cli/src/serve/httpAcpBridge.ts` (~283 lines) to
`@qwen-code/acp-bridge/spawnChannel`. This unblocks
`channels/base/AcpBridge.ts` and `vscode-ide-companion`'s
acpConnection from each reimplementing the child lifecycle — they can
now consume the same primitive.

Backward compatible: `cli/src/serve/httpAcpBridge.ts` imports the
lifted factory and re-exports it, so existing references in
`cli/src/serve/index.ts:90` and the factory's own internal usage
(`opts.channelFactory ?? defaultSpawnChannelFactory`) keep resolving.
Bridge tests that mock `defaultSpawnChannelFactory` via
`BridgeOptions.channelFactory` are unaffected.

Side cleanups: drops `spawn` / `ChildProcess` / `Readable` / `Writable`
/ `ndJsonStream` / `MissingCliEntryError` imports from
httpAcpBridge.ts (all only used by the lifted spawn factory).

* refactor(acp-bridge): lift BridgeClient + permission types to acp-bridge/bridgeClient (#4175 F1 step 2)

Second mechanical lift of #4175 F1 (acp-bridge package self-sufficiency).
Moves `BridgeClient` class (~700 LOC) + `PendingPermission` interface +
`PermissionResolutionRecord` interface + `MAX_RESOLVED_PERMISSION_RECORDS`
constant + early-event capacity constants + `describeStatKind` and
`sliceLineRange` helpers from `cli/src/serve/httpAcpBridge.ts` to
`@qwen-code/acp-bridge/bridgeClient`.

Design choice for SessionEntry boundary: introduce a minimal
`BridgeClientSessionEntry` interface in bridgeClient.ts with only the
four fields BridgeClient actually reads from the factory's richer
`SessionEntry` (`sessionId`, `events`, `pendingPermissionIds`,
`activePromptOriginatorClientId`). The factory's `SessionEntry`
structurally satisfies it — TypeScript's structural typing enforces
the match at the `resolveEntry` callback signature, so no explicit
conversion is required and the bridge package stays free of daemon-host
session-bookkeeping types.

Cross-package writeStderrLine handling: inline the 3-line helper in
bridgeClient.ts (mirrors the spawnChannel.ts pattern from F1 step 1)
so acp-bridge has no reverse dependency on `cli/src/utils/stdioHelpers`.

httpAcpBridge.ts shrinks from 4406 LOC to 3647 LOC (-759 lines).
Removed ACP SDK imports that only BridgeClient consumed: `Client`,
`RequestPermissionRequest`, `WriteTextFileRequest`,
`WriteTextFileResponse`, `ReadTextFileRequest`, `ReadTextFileResponse`,
`SessionNotification`. Kept the ones the factory still uses
(`CancelNotification`, `PromptRequest`, `RequestPermissionResponse`,
`SetSessionModelRequest`, `SetSessionModelResponse`).

Backward compatible: httpAcpBridge.ts re-exports `BridgeClient`,
`BridgeClientSessionEntry`, `PendingPermission`,
`PermissionResolutionRecord`, and `MAX_RESOLVED_PERMISSION_RECORDS` so
the `ChannelInfo.client: BridgeClient` field declaration below + any
embedder reaching into these types keep resolving.

* refactor(acp-bridge): lift createHttpAcpBridge factory to acp-bridge/bridge (#4175 F1 step 3)

Third + final mechanical lift of #4175 F1 (acp-bridge package
self-sufficiency). Moves the `createHttpAcpBridge` factory closure
(~3000 LOC) + `ChannelInfo` + `SessionEntry` interfaces + factory-only
helpers (`canonicalizeExistingAncestor`, `verifyParentWithinWorkspace`,
`withTimeout`, `isServeDebugLoggingEnabled`, `writeServeDebugLine`,
`hasControlCharacter`) + factory constants (`DEFAULT_INIT_TIMEOUT_MS`,
`MCP_RESTART_TIMEOUT_MS`, `DEFAULT_MAX_SESSIONS`, `MAX_EVENT_RING_SIZE`,
`DEFAULT_PERMISSION_TIMEOUT_MS`, `DEFAULT_MAX_PENDING_PER_SESSION`,
`MAX_DISPLAY_NAME_LENGTH`) from `cli/src/serve/httpAcpBridge.ts` to
`@qwen-code/acp-bridge/bridge`.

`cli/src/serve/httpAcpBridge.ts` shrinks from 3647 LOC to 97 LOC — a
pure re-export shim that preserves every existing relative import
path (`./httpAcpBridge.js`) so `server.ts`, `runQwenServe.ts`,
`workspaceAgents.ts`, `workspaceMemory.ts`, `index.ts`, plus the bridge
test suite, keep resolving without any call-site changes.

The new `bridge.ts` reuses what was already in acp-bridge (errors,
types, options, status helpers, channel types, event bus, workspace
paths) via local relative imports — no reverse dependency on `cli`.
`writeStderrLine` is inlined at the top of `bridge.ts` (same pattern as
`spawnChannel.ts` + `bridgeClient.ts` from F1 steps 1-2) so the
package self-contained promise holds.

Cumulative F1 impact across the 3 mechanical lift steps:
- httpAcpBridge.ts: 4682 LOC → 97 LOC (-4585 lines; the original file
  was 98% bridge core, 2% backward-compat re-exports)
- 3 new files in acp-bridge: spawnChannel.ts (~270 LOC), bridgeClient.ts
  (~745 LOC), bridge.ts (~3515 LOC)
- All daemon-host concerns (env snapshot, daemon preflight cells)
  remain in `cli/src/serve/daemonStatusProvider.ts` and reach the
  bridge through the `BridgeOptions.statusProvider` seam frozen by
  PR 22b/2.

`packages/cli/src/serve/httpAcpBridge.test.ts` (~6600 LOC) is
intentionally NOT moved in this commit — it currently imports
`createHttpAcpBridge` / `defaultSpawnChannelFactory` / `BridgeClient`
via the cli shim and keeps passing without changes. Moving it to
`acp-bridge/src/bridge.test.ts` is a follow-up worth tracking
separately so the production-code lift can land + be reviewed cleanly.

The `BridgeFileSystem` injection seam (originally bundled into F1 as
the 22b' scope) is also deferred to a follow-up so the mechanical lift
stays mechanical — design + implementation of the fs injection is its
own discussion.

* feat(acp-bridge): add BridgeFileSystem injection seam (#4175 F1 step 5, 22b' scope)

Adds the `BridgeFileSystem` injection seam originally scoped as #4175
22b'. When a `BridgeFileSystem` is wired through
`BridgeOptions.fileSystem`, `BridgeClient.readTextFile` and
`BridgeClient.writeTextFile` delegate to it instead of running their
inline `fs.realpath` / `fs.writeFile` / `fs.readFile` proxy.

This unblocks production `qwen serve` plumbing PR 18's
`WorkspaceFileSystem` (TOCTOU guards, symlink-substitution checks,
trust gate, `.gitignore`, audit hooks) into the ACP fs methods —
closing the `ws.ts:613` follow-up thread that has been tracked since
PR 18 landed. The serve-side adapter that wraps `WorkspaceFileSystem`
+ the `runQwenServe` wiring are intentionally split into the
immediate-follow-up so this PR stays focused on the seam design.

Backward compatible: `fileSystem` is optional on `BridgeOptions`.
Tests, Mode A in-process consumers, channels (`packages/channels/base/
AcpBridge.ts`), and the VSCode IDE companion all keep working
unchanged — they omit the field and `BridgeClient` falls through to
the inline proxy that has been the Stage 1 default since #3889.

API:
- `BridgeFileSystem.readText(params: ReadTextFileRequest):
  Promise<ReadTextFileResponse>`
- `BridgeFileSystem.writeText(params: WriteTextFileRequest):
  Promise<WriteTextFileResponse>`

The interface mirrors ACP SDK request/response types directly so the
adapter does the minimum amount of translation (`{ path, content }`
↔ `WorkspaceFileSystem`'s `ResolvedPath` brand types + options bag).

Folds in 3 of 4 Copilot inline comments from #4319 review:

1. `bridgeClient.ts` writeTextFile preserveMode comment said "fall
   through to umask defaults" for new files, but the code passes
   `mode: preserveMode?.mode ?? 0o600` to `fs.writeFile`. Updated the
   "BkwQW" comment + the inner catch-block comment to clarify that
   new files actually get the `0o600` default applied at writeFile
   time (NOT umask defaults — the explicit `mode` arg bypasses umask
   for atomicity per the `Blehd` comment block).

2. `bridgeFileSystem.ts` JSDoc referenced
   `cli/src/serve/bridgeFileSystemAdapter.ts` as if the file exists,
   but it's deferred to the immediate F1 follow-up PR. Reworded as
   "the immediate follow-up PR will land a serve-side adapter" so
   reviewers don't grep for a non-existent file.

3. `bridgeOptions.ts` `fileSystem` field JSDoc had the same wording
   issue ("Production `qwen serve` wires this to..."). Same fix — now
   says "The immediate F1 follow-up will land a serve-side adapter"
   so the deferred state is obvious.

Declined from this review round:

- Copilot inline #1 (`spawnChannel.ts:155` stderr forwarder drops
  empty lines): pre-existing behavior since #3889. F1 lifted verbatim
  — not a regression introduced here. Out of scope for a lift PR.
- github-actions bot summary: most items are pre-existing notes

  sliceLineRange benchmark threshold) on code the F1 lift moved

  positive — the file is 97 LOC after F1. Others are cosmetic

* docs(acp-bridge): tighten BridgeFileSystem contract + re-export type from shim

Self-review + code-reviewer agent fold-in, two changes:

1. `cli/src/serve/httpAcpBridge.ts` shim now re-exports
   `BridgeFileSystem` from `@qwen-code/acp-bridge/bridgeFileSystem`
   so the immediate F1 follow-up adapter (in `cli/src/serve/`)
   can import it via the established `./httpAcpBridge.js` path
   like every other daemon-side bridge import does. Without this
   the adapter would need to deep-import from acp-bridge while
   every other serve file goes through the shim — inconsistent.

2. `BridgeFileSystem.readText` + `writeText` JSDoc now spells out
   the two defensive gates the inline proxy carried (non-regular-
   file rejection + 100 MiB buffered-size cap for reads;
   write-then-rename atomicity + dangling-symlink walk-through +
   mode preservation + `0o600` new-file default for writes). When
   a `BridgeFileSystem` is injected, the inline path is FULLY
   bypassed — without the contract spelled out, a future adapter
   author could silently drop the `/dev/zero` / 500 MB log RSS
   defenses the inline path established.

Note on F1 CI: this PR targets `daemon_mode_b_main` but the
`.github/workflows/ci.yml` `pull_request` trigger is scoped to
`branches: main / release/**`, so the main CI workflow (Lint /
Test on Linux/macOS/Windows / CodeQL) does NOT run on this PR.
This is a by-design side effect of the new feature-cohesive
branching strategy — `daemon_mode_b_main → main` periodic merges
will trigger the full CI matrix, providing safety net coverage
before any F-series work lands on `main`. Locally verified:

* test(acp-bridge): cover BridgeFileSystem injection seam + extract shared writeStderrLine (#4319 wenshao review)

Folds in wenshao review on #4319:

1. **[Critical]** zero test coverage for the F1 step 5 `BridgeFileSystem`
   delegation branches in `BridgeClient.writeTextFile` /
   `BridgeClient.readTextFile` and the factory's
   `opts.fileSystem` → constructor positional-arg forwarding.

   New `packages/acp-bridge/src/bridgeClient.test.ts` adds 6 tests
   covering:
   - writeTextFile delegates to injected fileSystem.writeText (inline
     proxy fully bypassed; `fakeFs.writeText` called with the original
     params; `readText` mock not invoked)
   - writeTextFile invalid-path call succeeds purely via the mock
     when fileSystem is injected (proof that the inline `fs.realpath`
     path doesn't run)
   - readTextFile delegates to injected fileSystem.readText
   - readTextFile propagates injection errors to the caller
   - inline-fallback regression guard: write actually hits disk via
     the inline proxy when fileSystem is omitted (real tmp file
     round-trip)
   - same for read

   Why these matter: the 7-arg `BridgeClient` constructor places
   `fileSystem` at the tail as optional. A reordering — or dropping
   the arg from `bridge.ts` factory's `new BridgeClient(..., opts.fileSystem)`
   call — would silently bypass the adapter in production and the
   inline `fs.writeFile` raw-path would run with no audit / trust /
   TOCTOU coverage. The delegation tests would catch that because
   the mock fileSystem would never be invoked.

2. **[Suggestion]** `writeStderrLine` was defined identically in
   `bridge.ts:117` and `bridgeClient.ts:30` (22 call sites across the
   two files). Both consumers live in the SAME `@qwen-code/acp-bridge`
   package, so the original "no reverse-dep on cli" justification
   doesn't apply within the package. Extracted to
   `packages/acp-bridge/src/internal/stderrLine.ts` — a single source
   of truth that future behavior changes (timestamp prefix, log
   level, structured field) can edit once. `internal/` subpath is
   intentionally not in `package.json`'s `exports`, keeping the
   helper package-private. `spawnChannel.ts` deliberately does NOT
   consume it (its stderr writes use `process.stderr.write(prefix +
   line + '\n')` directly because each line carries its own
   `[serve pid=… cwd=…]` line prefix).

* test(acp-bridge): cover defaultSpawnChannelFactory env scrubbing + fix bridge.ts comment refs (#4319 wenshao round 2)

Folds in wenshao review on #4319 round 2 — 1 Critical + 2 Suggestions:

1. **[Critical] spawnChannel.ts has 0 unit tests, security-critical
   paths untested.** Now that `defaultSpawnChannelFactory` is a public
   export of `@qwen-code/acp-bridge`, channels + IDE consumers can't
   rely on cli-package integration tests for env-scrubbing guarantees.

   Refactored the inline env-scrubbing logic into a pure exported
   helper `scrubChildEnv(source, scrubbed, overrides)`. Behavior is
   byte-identical to the pre-extraction inline implementation; the
   factory body now reads:

       const childEnv = scrubChildEnv(
         process.env, SCRUBBED_CHILD_ENV_KEYS, childEnvOverrides);

   Added `packages/acp-bridge/src/spawnChannel.test.ts` with 12 tests
   covering:
   - shallow-clone (no aliasing into live process.env)
   - QWEN_SERVER_TOKEN stripping
   - non-scrubbed vars pass through
   - override-add a new key
   - override-replace an existing key
   - override with undefined deletes the key (PR 14 fix #4247 wenshao R5)
   - override CANNOT re-introduce a scrubbed key (defense in depth)
   - override CANNOT undo the scrub by setting undefined for a scrubbed key
   - override-apply-after-scrub ordering invariant
   - empty overrides equals no overrides
   - multi-key scrub for forward-compat (the WARNING comment on
     SCRUBBED_CHILD_ENV_KEYS anticipates a future sandboxed-agent
     mode expanding the denylist; this verifies the loop already
     handles that)

   The killChild SIGTERM→SIGKILL escalation + STDERR_LINE_CAP_CHARS
   truncation are NOT covered yet — they require either real child
   processes or extensive node:child_process mocking; both are
   orthogonal to the env-scrubbing security guarantees wenshao
   explicitly called out, and can land as a follow-up if anyone
   wants the full surface tested.

2. **[Suggestion] bridge.ts comments referenced a "consolidated re-
   export block earlier in this file" that doesn't exist in acp-bridge
   (only in the cli shim).** Fixed both occurrences (~line 292, ~line
   310) to point at the actual local import + the package barrel
   re-export.

3. **[Suggestion] bridge.ts canonicalizeWorkspace re-export comment
   referenced `./fs/paths.ts`.** Updated to mention the full lift
   chain: extracted to `cli/src/serve/fs/paths.ts` in PR 18, then
   lifted here to `./workspacePaths.ts` in PR 22b/1.

1. `bridgeClient.test.ts:20` JSDoc said "the 14-arg constructor's

2. `bridge.ts:3461` `canonicalizeWorkspace` re-export JSDoc no longer

   Reads cleaner as a present-tense pointer to `./workspacePaths.ts`
   (where the implementation actually lives now post-PR 22b/1).
   Git history covers the lift chain; the docstring should describe
   current state.

DECLINED + tracked separately:

- **[Critical]** `closeSession` + `killSession` use module-scoped
  `channelInfo` instead of `channelInfoForEntry(entry)` — channel-
  overlap edge case can kill the wrong channel. Wenshao explicitly

Five small adoptions from a second-pass code-reviewer agent review on
F1 (no new external comments — pre-emptive cleanup before reviewer
returns):

1. **`bridge.ts:290-313`** — deleted two standalone "InvalidPermission
   OptionError / WorkspaceInit* / McpServer* lifted to bridgeErrors"
   tombstone comments. Pre-22b they were load-bearing (explained why
   the class wasn't `class`-defined inline at that file location).
   Post-F1 the symbols are imported at the top of the file and the
   comments sit between unrelated code (`writeServeDebugLine` /
   `MAX_DISPLAY_NAME_LENGTH` / `DEFAULT_INIT_TIMEOUT_MS`) with no
   anchor. Dead doc — removed.

2. **`README.md`** — `spawnChannel` entry now lists `scrubChildEnv`
   alongside `defaultSpawnChannelFactory` + `killChild` +
   `SCRUBBED_CHILD_ENV_KEYS`. Channels / VSCode IDE consume the
   package barrel so the helper should be visible in the inventory.

3. **`package.json:description`** — refreshed from the PR 22a wording
   ("EventBus, AcpChannel, in-memory channel, PermissionMediator
   interface") to include F1 additions (`createHttpAcpBridge` /
   `BridgeClient` / `defaultSpawnChannelFactory` / `BridgeFileSystem`).
   Visible on `npm view`-style tooling + IDE hover so worth keeping
   current.

4. **`bridgeClient.test.ts:92-115`** — swapped `/proc/no-such-file`
   for `/this/dir/never/exists/file.txt` and reworded the comment.
   `/proc/` is Linux-only; on macOS / Windows the inline proxy's
   dangling-symlink fallback would write through to a path under
   root rather than failing. Test passed regardless (mock assertion,
   not real disk) but the comment overstated portability.

5. **`spawnChannel.test.ts:36`** — added a comment block explaining
   why the test deliberately hand-rolls the SCRUBBED set instead of
   importing the production `SCRUBBED_CHILD_ENV_KEYS`. The
   decoupling is intentional (pure-function parameterized test +
   forward-guard for future denylist expansion) but a naive reader
   would think it's an oversight.

Folds 3 unresolved review comments from the post-merge thread on #4297
(wenshao via qwen-latest agent) into F1 (#4319). All 3 touch
`acp-bridge/src/bridge.ts` — the same file F1 already moves the lifted
factory into — so consolidating here saves opening a separate
follow-up PR and keeps the security narrative in one reviewable
commit. The 2 cross-package fixes (`core/src/memory/const.ts` test
gap + `cli/src/serve/runQwenServe.ts` malformed-context fallback)
will land as their own small PRs after F1 merges.

#### Fix 1 (wenshao Critical, #4297 thread): `fs.unlink(target)`
arbitrary-file-deletion primitive in `verifyParentWithinWorkspace`
'create'-cleanup

After `fs.open(target, 'wx')` creates the empty file at the real
parent, an attacker with local workspace write access can swap the
parent directory for a symlink (`docs/` → `/etc`). The cleanup's
`fs.unlink(target)` re-resolves the TEXTUAL path through the
attacker's freshly-planted parent symlink, deleting whatever file
exists at the external location.

Fix: drop the `fs.unlink(target)` line. The 0-byte file at the
pre-race location is harmless (0 bytes, inside the workspace we'd
already verified) — leaving it over deleting an arbitrary external
file is the right safety trade. Comment block explains the
reasoning so future maintainers don't re-introduce the unlink.

#### Fix 2 (wenshao Critical): `O_TRUNC` arbitrary-file-truncation
primitive in workspace-init 'overwrite' branch

`O_TRUNC` causes the kernel to truncate the file to zero bytes AT
`open(2)` SYSCALL TIME — strictly before `verifyParentWithinWorkspace`
runs. A parent-symlink TOCTOU race between
`canonicalizeExistingAncestor` and this `open()` zeros the file at
the attacker-redirected location (arbitrary-file-truncation
primitive against any file the daemon UID can open). The pre-fix
code's own comment on `verifyParentWithinWorkspace` acknowledged
this as "Acceptable residual posture for the Stage-1 trust model";
wenshao pushed back that arbitrary-file-zeroing exceeds the
Stage-1 trust budget.

Fix: drop `O_TRUNC` from the open flags. Truncation moves to AFTER
`verifyParentWithinWorkspace` succeeds, via `fh.truncate(0)` on the
fd we already hold. fd-based truncate does NOT re-resolve the path
— an attacker swapping the parent symlink after we open can't
redirect the truncation.

#### Fix 3 (wenshao Suggestion): `canonicalizeExistingAncestor`
missing `ELOOP` catch

Circular symlinks in the parent path (`a -> b`, `b -> a`) cause
`fs.realpath` to fail with `ELOOP`. Without catching it, the error
propagates as an unstructured HTTP 500 instead of the typed
`WorkspaceInitSymlinkError` (HTTP 400) the route handler expects
from the workspace-init race-detection family.

Fix: add `'ELOOP'` to the caught error codes alongside `'ENOENT'`
and `'ENOTDIR'`. Walking up the parent chain when ELOOP hits at a
sub-component preserves the existing "walk to the deepest extant
ancestor" contract — the deepest realpath-able ancestor still
dictates the canonical prefix.

#### Why no new tests in this commit

- Fix 1 is a single-line removal: any regression that re-adds the
  unlink would be caught by reviewing the diff; existing 174-test
  `httpAcpBridge.test.ts` integration suite confirms the create-path
  still works (file is created + closed correctly; only the
  attacker-cleanup branch changes).
- Fix 2 is a structural move (truncate from open-time to post-verify);
  the existing overwrite-init integration tests confirm the
  end-to-end behavior is unchanged (file ends up empty after init).
  Adding a TOCTOU race regression test requires controlled
  filesystem-race simulation that exceeds reasonable test infra
  scope for this PR.
- Fix 3 is a one-word addition to an error code list; the
  `canonicalizeExistingAncestor` helper is module-private and the
  integration test for circular-symlink → typed 400 would require
  exporting it OR setting up a real circular-symlink workspace.
  Both routes widen scope beyond the security fix itself; the
  high-level behavior is verifiable by the existing route-error-
  mapping test pattern + diff review.

A follow-up PR can add the integration tests once the security fix
itself has shipped; the immediate priority is closing the
arbitrary-file-deletion + arbitrary-file-truncation primitives.

- 62/62 acp-bridge tests pass

* fix: post-merge Codex P2 fold-in — MCP restart disabled-tools normalization + SDK timeout headroom (#4319)

Folds in 2 P2 findings from a Codex review run on `git diff main...HEAD`
of F1 PR #4319. Both are pre-existing in code merged into
`daemon_mode_b_main` before F1 was created (#4282 PR 17), but they're
tiny tactical fixes (~25 LOC + 1 LOC) on the same integration branch
the same reviewer (wenshao) already engages with, so folding into F1
saves an extra follow-up PR cycle.

#### Fix 1: normalize disabled tool names during MCP restart refresh

`packages/cli/src/acp-integration/acpAgent.ts:1563-1566`

The bootstrap path in `cli/src/config/config.ts:1426-1434` applies a
4-step normalization to `tools.disabled`:
  1. typeof string filter
  2. .trim()
  3. drop empty after trim
  4. dedupe via Set

The MCP-restart refresh path only did step 1, then stored the raw
strings. `ToolRegistry` checks disabled tools with EXACT
`Set.has(tool.name)`, so a tool disabled at boot as `' Foo '` (or
`'Foo\n'`) is no longer matched after `restartMcpServer` and gets
silently re-registered. This contradicts the documented "toggle +
restart" workflow that #4282 PR 17 advertised.

Fix: mirror the bootstrap normalization verbatim before
`setDisabledTools`. Adds 6 lines + a 7-line comment pointing at the
bootstrap reference for future maintainers.

#### Fix 2: add headroom to MCP restart SDK timeout

`packages/sdk-typescript/src/daemon/DaemonClient.ts:102`

The SDK's `MCP_RESTART_DEFAULT_TIMEOUT_MS` was EXACTLY 300_000ms, the
same ceiling the daemon's own `MCP_RESTART_TIMEOUT_MS` uses for the
upper bound on a single MCP rediscovery. For restarts that finish
(or fail with a typed `McpServerRestartFailedError` JSON envelope)
near 300s, the client `AbortSignal` could fire BEFORE the daemon had
finished serializing + transmitting the response, yielding a client
`TimeoutError` even though the daemon was still within its own
budget.

Fix: bump to 330_000ms (10% / 30s headroom over the daemon ceiling).
Comment updated to call out the race + the rationale for the
specific headroom value. Callers needing tighter caps still pass
their own `timeoutMs` to `restartMcpServer`.

#### Why folded into F1 vs separate follow-up PRs

These are post-merge findings on `#4282 PR 17` code, not F1-introduced
regressions. Normally we'd track as separate follow-up issues (mirror
of the #4325 / `channelInfo` decline). But:

- Both fixes are TINY (~25 LOC + ~2 LOC including comment); the bridge
  security fold-in commit `7bd66c6e8` set the precedent of folding in
  small same-branch issues when the cost-benefit favors closing them
  immediately.
- Same reviewer (wenshao via qwen-latest agent) — won't be confused
  by the scope expansion; in fact the original PR 17 commenter is
  also the one who'd review the follow-up issue's fix.
- Both fixes target `daemon_mode_b_main`-only paths (MCP restart route
  added by PR 17 lives on the integration branch).
- Saves opening 2 trivial follow-up issues that would just sit until
  someone picks them up.

#### Verification

- sdk-typescript: 424/424 tests pass (no test hardcoded the old
  300_000 default — only the constant declaration itself referenced it)
- cli acp-integration: 282/282 tests pass (no test exercised the
  exact whitespace-bearing disabled-tools scenario, so no test
  changes were strictly required; a regression test would belong in
  a separate test-coverage PR alongside the const.ts test gap from
  the #4297 unresolved-comment thread)
- typecheck clean across cli + sdk-typescript

Decouple trigger from completion: POST /session/:id/prompt now returns
202 Accepted immediately with `{ promptId, lastEventId }`. Completion
is delivered via `turn_complete` / `turn_error` SSE events correlated
by promptId.

- Bridge publishes `turn_complete` and `turn_error` events after
  sendPrompt settles (abort-cancelled prompts are suppressed)
- Bridge exposes `getSessionLastEventId()` so the server can snapshot
  the cursor before enqueuing
- DaemonClient.prompt() transparently handles 202 by opening a
  temporary SSE subscription and awaiting the matching turn event
- Web-shell observes `turn_complete` for passive session viewers
- Capability tag `non_blocking_prompt` advertised for feature detection
- Deadline enforcement preserved: timer aborts the prompt server-side,
  surfaced through `turn_error` SSE event instead of HTTP 504

- Remove emitPromptDeadline504 (deadline surfaced via turn_error SSE)

SDK DaemonClient:
- Add promptNonBlocking() for callers with existing SSE subscriptions
- Add matchTurnEvent() shared utility for turn event correlation
- prompt() retains temporary SSE fallback for standalone callers
- Export NonBlockingPromptAccepted, matchTurnEvent, isNonBlockingAccepted

SDK DaemonSessionClient:
- prompt() uses promptNonBlocking() when SSE subscription is active,
  resolving via _pendingPrompts map (like ACP transport request routing)
- iterateEvents() intercepts turn_complete/turn_error and dispatches
  to pending prompts before yielding to the consumer
- Falls back to DaemonClient.prompt() (temp SSE) when no subscription

* fix(daemon): plug abort-listener leak in DaemonSessionClient.prompt

When prompt() resolved via _dispatchTurnEvent (turn_complete SSE),
the abort listener on the caller's signal was never removed. Over a
long-lived session each prompt call accumulated another leaked
listener. Additionally, if the signal fired after resolution, the
stale handler called cancel() — potentially cancelling an unrelated
in-flight prompt.

Fix: wrap resolve/reject to removeEventListener on settlement.

Also: use typed DaemonTurnCompleteData instead of ad-hoc cast in
web-shell passive turn_complete handler.

* fix(daemon): type guard in _dispatchTurnEvent, code coercion, passive turn_error

- Add type guard (turn_complete/turn_error only) in _dispatchTurnEvent
  before extracting promptId. Without this, a future event type
  carrying promptId in data would silently delete the pending entry
  without resolving or rejecting the promise.

- Fix String(undefined) producing "undefined" in broadcastTurnError.
  When err.code is undefined, 'code' in err is true but
  String(undefined) yields the truthy string "undefined", bypassing
  the conditional spread and stamping a misleading error code.

- Handle turn_error for passive observers in web-shell. Passive tabs
  viewing a session that hits turn_error (agent crash, transport
  failure) now dispatch assistant.done instead of staying stuck in
  the thinking state indefinitely.

- fmtCategoryRow: guard against zero contextWindowSize division

Suggestion fixes:
- MemoryDialog: await reloadMemory() before showing success message

  to prevent indefinite hang when daemon is unresponsive
- ToolGroup: auto-expand bash/shell/execute_command tool output by default
- Add shell output tests for transcriptToMessages

* fix(webui): fix state_resync_required handling and catchingUp flag

- Differentiate state_resync_required by reason: epoch_reset resets store
  and replays on same stream; ring_evicted preserves awaitingResync and
  continues on same stream; other reasons keep original break+reconnect
- Clear awaitingResync on replay_complete so post-replay events flow
- Set catchingUp when activeSession.lastEventId is present, not only on
  same-session reconnect (fixes resume catchingUp indicator)

* fix(web-shell,webui): add getTasks action and fix broken reference after rebase

- Fix App.tsx: actions.getTasks → sessionActions.getTasks (variable renamed
  during refactor but this callsite was missed during rebase merge)

* fix(webui): fix releaseSession to use closeSession instead of detach

releaseSession was incorrectly calling detachDaemonClient with the
current client's ID, which only decremented attachCount without
actually closing the target session. Replace with
session.client.closeSession() (DELETE /session/:id) to properly
terminate the session. Also fix sendShellCommand to use a distinct
shellKey to avoid colliding with prompt AbortControllers.

* feat(webui): add non-blocking prompt settlement and passive turn event handling

- Add settleActivePromptFromTurnEvent to resolve/reject active prompts
  from turn_complete/turn_error SSE events in the Provider event loop
- Add isPromptLifecycleTurnEvent filter to prevent turn events from being
  dispatched to the transcript store as unrecognized debug events
- Add waitForAcceptedPromptCompletion in actions.ts to bridge the gap
  between 202-accepted prompts and their eventual turn completion
- Extend ActivePrompt type with promptId, resolve/reject callbacks, and
  pendingResult/pendingError for deferred settlement
- Add passive observer handling for turn_complete/turn_error so non-sender
  tabs correctly end the streaming state
- Add tests for non-blocking prompt acceptance and early turn completion

* feat(sdk): add serve-bridge MCP server & rename mcp → daemon-mcp (#4555)

* feat(sdk): add MCP server bridge wrapping qwen serve HTTP API

Expose qwen serve's HTTP endpoints as MCP tools via a stdio-based
MCP server. This allows any MCP-compatible client (Claude Desktop,
Cursor, VS Code, etc.) to interact with a running qwen serve daemon
directly through the standard MCP protocol.

The bridge provides 31 tools covering session lifecycle, agent
interaction (prompt/cancel), workspace file operations, and
workspace configuration management. A standalone bin entry
(`qwen-serve-mcp`) is included for direct CLI usage.

* docs(sdk): add README for qwen-serve-bridge MCP server

Includes usage instructions, environment variables, MCP client
configuration examples, tool listing, session management notes,
and verification commands.

* chore(sdk): update copyright year to 2026 in serve-bridge files

* fix(sdk): correct file_stat/dir_list/glob endpoints and add process signal handling

- file_stat now calls GET /stat instead of readWorkspaceFile fallback
- dir_list now calls GET /list for proper directory listing
- glob now calls GET /glob for pattern matching
- Add daemonFetch() helper for raw HTTP calls to endpoints not in DaemonClient
- Add SIGINT/SIGTERM graceful shutdown in bin.ts
- Add unhandledRejection handler to prevent silent crashes
- Exit cleanly when stdin pipe closes (parent process gone)

* docs(sdk): add external usage instructions for qwen-serve-bridge

Document three configuration methods: npx (zero-install), global
install, and local path (dev). Clarify Node >=22 requirement and
add qwen serve startup options.

* fix(sdk): collect agent response text via SSE in prompt tool

The prompt endpoint only returns stopReason synchronously. Actual
response content is streamed via session SSE events. Now the prompt
tool subscribes to events in parallel, collects agent_message_chunk
texts, and returns the full response in the result.

* refactor(sdk): rename src/mcp to src/daemon-mcp

Rename the MCP utilities directory to better reflect its role as
daemon-specific MCP tooling. Update all import paths in index.ts,
Query.ts, and the bin entry in package.json.

* docs(sdk): update README paths after mcp → daemon-mcp rename

* test(sdk): add unit tests for serve-bridge MCP server

22 tests covering:
- Server creation and configuration
- Session state management (resolveSessionId, defaultSessionId)
- Auth headers and daemonFetch helper
- Error handler wrapper
- Tool registration counts (31 total, no duplicates)
- session_create sets defaultSessionId
- session_close clears defaultSessionId
- prompt tool SSE event collection

Also fix createSdkMcpServer.test.ts import paths after mcp → daemon-mcp rename.

* feat(sdk): implement persistent SSE connection for serve-bridge prompt

Replace per-prompt SSE subscription with a persistent connection that is
established at session_create and torn down at session_close. This
eliminates the 200ms delay and race condition that caused unreliable
response collection in Qoder.

- Add SessionEventStream/PromptCollector types and lifecycle helpers
- Rewrite prompt handler to use shared persistent stream
- Start SSE on session_create/load/resume, stop on session_close
- Update unit tests for new persistent SSE pattern

* fix(sdk): resolve P0 issues in serve-bridge MCP tools

1. prompt tool: return explicit timeout error instead of silently
   returning empty response when SSE collection times out (30s)
2. health tool: remove unused `deep` parameter that was never passed
   to the underlying DaemonClient.health() API

* refactor(sdk): improve daemon-mcp architecture (P1/P2 fixes)

P1 fixes:
- Split types.ts into types.ts (interfaces), sse.ts (SSE lifecycle),
  helpers.ts (handler/resolveSessionId/daemonFetch) for separation of concerns
- Add fileStat/dirList/glob methods to DaemonClient, removing raw
  daemonFetch usage from workspaceRead tools
- Move session_set_model and session_context from agent.ts to session.ts
  for naming consistency
- Add error logging with stack traces in handler() wrapper

P2 fixes:
- Remove unused exports from formatters.ts (formatToolResult,
  formatTextResult, mergeToolResults, isValidContentBlock)
- Fix copyright year to 2026 in tool.ts and createSdkMcpServer.ts

* fix(sdk): use bracket notation for process.env access in bin.ts

* fix(sdk): address PR review High-priority feedback

1. PromptCollector: add `resolved` flag to guard against double-resolve
   race between _meta event and stopEventStream teardown
2. session_create: stop SSE for previous default session before creating
   a new one to prevent connection leaks
3. bin.ts: include full stack trace in unhandledRejection handler for
   production debugging

* fix(sdk): address Medium/Low review feedback for serve-bridge

- Add timeout behavior documentation to prompt tool description
- Fix README token documentation (remove misleading loopback claim)
- Add session TTL cleanup (30min idle timeout) to prevent SSE connection leaks
- Extract workspace_agents_manage switch cases into separate functions
- Track lastActivityMs on SessionEventStream for TTL-based cleanup

* fix(sdk): resolve P0 review issues — _meta check level & global scope security

- Fix _meta check: daemon emits _meta at update level, not inside content.
  Previous code checked 'content._meta' which was always false, causing
  every prompt to wait the full 30s timeout before returning.
- Security: restrict global scope writes by default. MCP bridge now blocks
  workspace_memory_write and workspace_agents_manage with scope='global'
  unless QWEN_BRIDGE_ALLOW_GLOBAL_SCOPE=true is set. Prevents cross-workspace
  prompt injection via compromised MCP clients.
- Fix test: add missing lastActivityMs and allowGlobalScope to mock objects.

* fix(sdk): resolve P1 review issues — SSE leak, error handling, concurrent guard

- session_load/session_resume: stop previous default session's SSE stream
  before starting a new one (matching session_create behavior). Also add
  workspaceCwd fallback for consistency.
- SSE catch block: log unexpected disconnections (skip AbortError from
  intentional close) and resolve active collector in finally block so
  prompt doesn't hang 30s on network failures.
- Concurrent prompt guard: reject second prompt on same session if one
  is already in progress, preventing collector corruption.

* fix(sdk): resolve P2 review issues — robustness and cleanup

- close(): abort all active SSE streams on server shutdown
- ReDoS: replace regex /\/+$/ with hand-rolled loop (matches DaemonClient)
- file_write: validate expected_hash required for replace mode
- prompt: clear setTimeout on normal resolve (prevent 30s timer leak)
- prompt: return timeout as distinct stop_reason with warning field
- prompt_cancel: resolve active collector so prompt returns immediately
- session_create: stop old SSE after new session confirmed (not before)
- session_close: close HTTP session before stopping SSE stream
- session_load/resume: add workspaceCwd fallback for consistency
- bin.ts: fix stale comment path (mcp → daemon-mcp)
- Remove dead code: authHeaders/daemonFetch (unused by any tool handler)
- workspaceWrite: add default case to switch, fix arrow-body-style lint

* fix(sdk): address final review — ordering, SSE safety, build, tests

- session_load/resume: move stopEventStream after API success (match
  session_create pattern), prevents bridge becoming unusable on failure
- SSE finally: guard eventStreams.delete with identity check to prevent
  deleting a newly created stream; clear defaultSessionId on disconnect
- prompt timeout: cancel daemon-side processing to prevent stale chunks
  contaminating the next prompt
- session_close: wrap closeSession in try/finally so SSE always cleans up
- resolveSessionId: bump lastActivityMs so workspace operations reset TTL
- build: add esbuild entry for serve-bridge/bin.ts with shebang banner
- tests: add coverage for concurrent prompt guard, prompt_cancel resolve,
  global scope rejection, file_write hash validation

- Fix startEventStream stale entry: check abortCtrl.signal.aborted before
  skipping re-creation of dead SSE connections
- Fix timedOut race condition: use collector.resolved to prevent false

- Add interrupted flag to PromptCollector: stopEventStream and SSE
  finally block now mark collector as interrupted, prompt handler returns
  distinct stop_reason:'interrupted' with warning
- Handle daemon error/fail SSE events: log to stderr and resolve collector
  immediately instead of waiting for 30s timeout
- Move validateGlobalScope to write-only branches in workspace_agents_manage:
  list/get operations no longer blocked by scope check
- Fix shutdown() to await server.instance.close() before process.exit
- Add tests for approval mode guard and read-only agents_manage

* fix(sdk): document _meta protocol contract assumption in SSE handler

* fix(sdk): address R7 review — interrupted consistency, auto-edit guard, cancel resilience

- Set interrupted=true before resolving collector on daemon error events
  (consistent with finally block and stopEventStream)
- Return isError:true on interrupted path in prompt handler
  (consistent with timeout path)
- Add auto-edit to restricted approval modes list
  (same risk level as auto/yolo)
- Wrap prompt_cancel's client.cancel() in try/catch so collector
  always resolves even if daemon is unreachable

* test(sdk): add regression tests for R7 fixes

- Assert prompt_cancel sets collector.interrupted = true
- Add auto-edit approval mode rejection test

* fix(sdk): harden bridge security and improve close lifecycle

- Guard workspace_tool_toggle behind allowGlobalScope
- Validate handleAgentUpdate requires at least one field to update
- Use SDK onclose lifecycle hook instead of monkey-patching close()
- Improve prompt tool description accuracy for timeout behavior
- Add tests for tool_toggle guard and agents_manage update validation

* fix(sdk): guard mcp_restart and fix agent update field validation

- Add allowGlobalScope guard to workspace_mcp_restart (consistent with
  workspace_tool_toggle — restarting MCP servers is equally disruptive)
- Remove scope from hasField check in handleAgentUpdate (scope is a
  routing parameter, not an update field — passing only scope would
  POST an empty body to the daemon)

* fix(sdk): address doudouOUC review — imports, descriptions, error messages

- Remove runtime re-exports from types.ts; tool files now import
  directly from sse.js/helpers.js to avoid circular dependency risks
- Add best-effort comment on SSE error event regex explaining limitations
- Rewrite prompt tool description to clarify 30s is post-response
  collection timeout, not overall timeout
- Split approval mode error messages: distinguish dangerous-mode vs
  persist-restricted cases
- Mark name parameter as (create only) in agents_manage schema
- Log close errors in shutdown instead of silently swallowing

* feat(telemetry): trace daemon prompt lifecycle (#4556)

* feat(telemetry): trace daemon prompt lifecycle

Connect qwen serve HTTP routes, ACP bridge dispatch, and ACP child prompt execution through OpenTelemetry context propagation. The daemon injects reserved qwen.telemetry metadata internally so clients do not need to pass trace context.

Closes #4554

* fix(telemetry): emit daemon bridge events as spans

Record bridge telemetry events as short daemon bridge spans when they fire outside an active request or prompt context, so asynchronous channel exits remain observable.

Co-authored-by: Qwen-Coder <[email protected]>

* fix(telemetry): address wenshao review — 10 fixes

- recordDaemonHttpResponse: don't clobber ERROR with OK on non-5xx
- finish(): remove signal listeners synchronously before async telemetry shutdown
- extractDaemonTraceContext: reject all-zero IDs, include tracestate, set isRemote
- propagation.inject: wrap in try/catch for consistency
- injectPromptContext: move inside prompt.dispatch span for correct parent
- withDaemonSpan: guard on isTelemetrySdkInitialized()
- toOtelAttributes: remove identity function, pass attributes directly
- injectDaemonTraceContext: early-return when no active span (avoid empty _meta)
- emitDaemonLog: remove redundant event.timestamp attribute
- NOOP_BRIDGE_TELEMETRY: drop async, add short-circuit for missing keys

* fix(telemetry): remove TraceState constructor usage in manual fallback

TraceState is a type-only export from @opentelemetry/api (not a
runtime constructor). The manual fallback path now omits tracestate
since the primary propagation.extract path already handles it.

* fix(telemetry): address wenshao review round 3

- withDaemonSpan: pass undefined (not getSpan result) when SDK off
- stripReservedTraceMeta: skip copy when no reserved keys present
- sendBridgeErrorImpl: truncate error.message in emitDaemonLog

* fix(telemetry): address wenshao review round 4

- extractDaemonTraceContext: use ROOT_CONTEXT as extraction base to
  prevent incorrect parent-child when agent has its own active span
- extractDaemonTraceContext (manual fallback): already has isRemote:true
  and ROOT_CONTEXT from previous fix — confirmed consistent
- injectDaemonTraceContext: skip _meta assignment when original had no
  _meta and no trace headers were injected (match NOOP behavior)
- withInteractionSpan: cancelled prompts get UNSET instead of OK so
  dashboards can distinguish cancelled from successful
- emitDaemonLog: use OTel built-in timestamp field instead of custom
  attribute

* fix(telemetry): address wenshao review round 5

- Import DAEMON_TRACEPARENT/TRACESTATE_META_KEY from core instead of
  redeclaring locally in bridge.ts (drift risk)
- Add isTelemetrySdkInitialized() guard to event() in
  createDaemonBridgeTelemetry for consistency with siblings
- Remove setStatus(ERROR, "HTTP 500") from recordDaemonHttpResponse
  to avoid overwriting the descriptive error message already set by
  recordDaemonError

* feat(daemon): add request-level logging for serve routes (#4606)

* feat(daemon): add request-level logging for serve routes

Add access-log middleware and inline business-context logs to the daemon
server. Previously only 5xx errors were logged via sendBridgeError,
making it impossible to debug issues like "frontend says /recap returned
nothing" — the backend had zero trace of the request.

Changes:
- Access-log middleware: logs method, path, sessionId, clientId, status,
  and durationMs for every completed request (excludes GET /health and
  SSE /events to avoid noise)
- Inline logs for key routes: session spawn/attach, prompt enqueue,
  cancel, recap (distinguishes null vs generated), shell command
  completion, and SSE stream open/close with duration
- All logging gated on daemonLog existence (tests/embeds unaffected)

* feat(daemon): add full-chain logging for recap/prompt/cancel/shell

Extend request-level logging deeper into the call chain so operators can
trace a request from HTTP route through bridge → ACP child → core service.

- bridge.ts: log entry for sendPrompt, cancelSession,
  executeShellCommand, and generateSessionRecap (entry + result) via
  onDiagnosticLine (lands in daemon log file unconditionally)
- acpAgent.ts: log ext-method receipt and completion for recap handler
  via debugLogger (lands in per-session debug file)
- sessionRecap.ts: add debugLogger.debug at every early-return path
  (no geminiClient, history too short, empty dialog, empty model
  response, tag extraction failed) so recap=null is always attributable

* fix(daemon): move access-log before auth, fix SSE exclusion, add load/resume log

- Move access-log middleware before bearerAuth and JSON parser so 401
  auth rejections and malformed-body 400s are captured in the daemon log
- Fix /events exclusion: only suppress logging for successful SSE
  streams (status 200); failed SSE handshakes (4xx) are still recorded
- Add inline log for POST /session/:id/load and /resume handlers

* fix(daemon): log 5xx at error level, remove unnecessary type casts

- Access-log middleware now uses error level for 5xx responses (was
  info, making them invisible to level-filtered log queries)
- Remove unnecessary type casts on response.recap and result.exitCode
  — TypeScript already infers the correct types from bridge methods

* fix(daemon): use space separator in access-log route field

Align with the existing convention used by sendBridgeError (e.g.
"POST /session/:id/recap") so grep/filtering across both access-log
and error-log entries works with a single pattern.

* fix(daemon): address wenshao review — dedup 5xx, reap log, prompt clientId+errName

- Remove middleware error-level for 5xx (sendBridgeError is authoritative;
  middleware duplicating at error inflates alert counts)
- Add warn log when spawned session is immediately reaped due to client
  disconnect before response delivery
- Add clientId to all prompt log lines (enqueued/completed/failed) for
  consistency with other route logs
- Include err.name in prompt-turn-failed message so operators can
  distinguish PromptDeadlineExceededError (routine) from
  BridgeChannelClosedError (infra issue)

* fix(daemon): exclude heartbeat from access-log (high-frequency probe)

Heartbeat fires every 30s per active session — with 3 sessions that's
360 log lines/hour of noise drowning real signal. Same exclusion logic
as GET /health.

* feat(web-shell): add /delete command with batch delete support (#4603)

* feat(web-shell): add /delete command with batch delete support

Add a /delete slash command to the web-shell that allows users to
permanently delete session data files. Supports both single-session
and multi-select batch deletion with proper error handling.

Changes:
- Add POST /sessions/delete batch endpoint to daemon server
- Add deleteSessionsData() to SDK DaemonClient
- Add DeleteSessionDialog with multi-select (Space to toggle, Enter
  to confirm) and search/filter support
- Add deleteSession/deleteSessions workspace actions and hooks
- Distinguish errors vs notFound in single-delete action (throw on
  real errors, return false only for notFound)
- Surface failure reasons in batch delete (allFailed / partialFail
  messages include first error detail)
- Normalize Error objects to string messages in server JSON response
- Add tests for server route, SDK client, and workspace provider

* fix(web-shell,cli): address PR review issues for batch delete

- Pass clientId to deleteSessionsData for ownership validation
- Add sessionIds max length (100) and deduplication
- Parallelize bridge.closeSession via Promise.allSettled
- Add server-side logging for close failures
- Reconcile selectedIds with search filter before delete
- Prune selectedIds when search query changes
- Fix notFound counting: only errors are failures
- Fix partial failure double toast: single error message
- Fix empty-state: show error message when load fails
- Fix hardcoded English "matches" → i18n key
- Remove dead targetSession parameter
- Align checkbox for current session ([-] instead of spaces)
- Add happy path test for batch delete
- Reload session list on notFound-only response

* fix(web-shell,cli): remove clientId ownership check for batch delete and improve UX

- Remove clientId validation from batch delete endpoint since workspace-level
  access is sufficient authorization. The per-tab clientId check prevented
  cross-tab deletion of active sessions without real security benefit (user
  can bypass by resuming the session first).
- Wrap filtered sessions list in useMemo to stabilize reference and prevent
  unnecessary keydown listener teardown/re-register on each render.
- Include notFound sessions in onDeleted callback so the toast correctly
  reports the total count of cleaned-up sessions.

Generated with AI

* fix(web-shell,cli): address round-2 review — logging, dead code, tests

- Add comment documenting intentional no-clientId in batch delete
- Log removeSessions filesystem errors to stderr for debuggability
- Count notFound as success in deleteSession for proper UI reload
- Remove dead if (!deleteSessions) / if (!deleteSession) guards
- Fix partial-failure double-wrapped toast message
- Reset selectedIdx when exiting search mode via Enter
- Add 5 batch tests: mixed outcomes, max-100 cap, non-string
  validation, dedup, and file preservation on error

Generated with AI

* fix(web-shell,cli): fix partial-failure toast and add 500 catch block test

- Revert partial-failure handler to use delete.partialFail i18n key
  through onError only, removing contradictory onDeleted call
- Add test for removeSessions unexpected throw (500 catch block)

* refactor(cli): use static import for SessionService in batch delete test

C3: Bridge throws error with data.errorKind='acp_channel_unavailable' instead

* fix(serve): address rounds 5-7 review items — build, security, correctness (T2.8 #4514)

Build breakers (Critical):
- events.ts: add missing /** JSDoc opener for DaemonMcpServerAddedData
- events.ts: add missing `: undefined` arm in followup_suggestion ternary
- events.ts: close isFollowupSuggestionData function body (missing ); })

Security (Critical):
- acpAgent: strip authProviderType, includeTools, excludeTools, cwd from
  runtime-added server configs (prevents SSRF via cloud creds leak and
  arbitrary cwd spawn)
- mcp-client-manager: reject servers in excludedMcpServers blocklist
- acpAgent: add Array.isArray guard to config validation

Correctness:
- mcp-client-manager: identity-check on pooledConnections.delete in remove
  (prevents concurrent add+remove race deleting NEW pool entry)
- mcp-client-manager: add client.disconnect() in catch block for
  standalone path (prevents transport/process leak)
- mcp-client-manager: add consecutiveFailures, isReconnecting,
  dropRefusalEntry cleanup in removeRuntimeMcpServer
- mcp-client-manager: emit mcp-client-update on spawn failure cleanup
- mcp-client-manager: extract exitCode from error when available
- mcp-client-manager: fix replaced=true → false for same-fingerprint
  idempotent re-add (no transport was torn down)
- server.ts: whitelist error fields in sendBridgeError responses
  (prevent unbounded internal ACP data spread)
- bridge.ts: remove dead try/catch in addRuntimeMcpServer (all branches
  just re-threw)
- bridge.ts: add try/catch to removeRuntimeMcpServer for error mapping
- bridge.ts: narrow AddOk.transport to literal union type

SDK / DX:
- DaemonClient: add timeoutMs param to addRuntimeMcpServer (default 330s,
  matching restartMcpServer — prevents 30s SDK timeout vs 5min bridge)
- mcp-client-manager: add debugLogger.info at method entry

Docs:
- qwen-serve.md: clarify replaced:true vs replaced:false semantics

* fix(serve): strip env field, add status cleanup and name validation (T2.8 #4514)

Security:
- Strip `env` from runtime-added MCP server configs (prevents
  NODE_OPTIONS/LD_PRELOAD injection via HTTP body)

Correctness:
- Add `removeMCPServerStatus(name)` in spawn-failure catch block
  (prevents stale CONNECTING entry in status registry)

Hardening:
- Add name validation (charset + length) to ACP ext-method handlers
  for both add and remove (matches HTTP route validation)

* fix(serve): strip oauth/headers, reject __proto__ names, fix remove timeout (T2.8 #4514)

Security:
- Strip `oauth` and `headers` from runtime-added configs (prevents
  credential exfiltration via OAuth flow and header injection)
- Reject `__proto__`, `constructor`, `prototype` as server names
  (prevents prototype pollution when name becomes object key)

SDK:
- Add timeoutMs to removeRuntimeMcpServer (match add's 330s default)

Docs:
- Remove `env` from POST example (stripped by daemon since 66dc4ce1c)
- Document stripped fields list

* fix(serve): strip type field, add __proto__ rejection to HTTP routes (T2.8 #4514)

Security:
- Strip `type` from runtime config (prevents SDK transport routing bypass)
- Add __proto__/constructor/prototype rejection to HTTP POST route
  (ACP handlers already had this; HTTP routes were missing it)

Docs:
- Add includeTools, excludeTools, type to stripped-fields list

Split combined regex + reserved-name validation into separate checks with
distinct error messages on both POST and DELETE routes. Added tests for
__proto__/constructor/prototype rejection on POST, and MAX_SERVER_NAME_LENGTH +
reserved-name rejection on DELETE.

* feat(telemetry): add tool spans and session.id to daemon/ACP path

Add interaction-level and tool-level OTel spans to the daemon's ACP
Session.ts, closing the observability gap described in #4602.

Changes:
- session-tracing.ts: emit session.id on llm_request, tool, and
  tool.execution spans via getCurrentSessionId()
- Session.ts runTool(): wrap tool lifecycle in startToolSpan /
  runInToolSpanContext / endToolSpan; wrap invocation.execute() in
  startToolExecutionSpan / endToolExecutionSpan
- Session.ts #executePrompt: emit logConversationFinishedEvent at

- Session.ts #executeCronPrompt: wrap body in withInteractionSpan
  so cron tool calls also get proper trace hierarchy

* fix(telemetry): address Copilot review — cron abort status + exec span cancellation

- Cron path getResultStatus now checks ac.signal.aborted so aborted
  cron runs record turn_status='cancelled' instead of 'ok'
- Tool execution span success path now checks abortSignal.aborted,
  aligning with coreToolScheduler cancellation semantics

* fix(telemetry): correct session.id, span outcomes, conversation_finished coverage

Address wenshao + Copilot review on the daemon/ACP telemetry path.

- session-tracing.ts: derive session.id for llm_request/tool/tool.execution
  spans from the per-session parent span context (resolveSessionId) instead of
  the process-global getCurrentSessionId(). A daemon hosts many sessions in one
  process, so the global cross-stamped child spans with whichever session last
  initialized telemetry while the interaction span carried the correct id.
  Falls back to the global for the single-session CLI path. [wenshao Critical]

- Session.ts #executePrompt: move logConversationFinishedEvent into a finally
  wrapping the whole turn loop so cancelled / no-stream / API-error / rate-limit
  terminal paths also emit (previously only the clean stop-hook path did).
  Emitted for all approval modes — an intentional divergence from the CLI's
  YOLO-only gating, since daemon turns run autonomously regardless of mode.
  [wenshao Critical + Suggestion, Copilot turnCount]

- Session.ts #executeCronPrompt: emit conversation_finished on every terminal
  cron path (clean / abort / caught error). [wenshao Critical]

- Session.ts runTool success path: reflect toolResult.error and cancellation in
  logToolCall / recordToolResult / the tool span instead of hardcoding success,
  so soft tool failures are no longer mislabeled as successful. [Copilot]

- Session.ts tool-confirmation Cancel: route through earlyErrorResponse so
  spanError carries the cancellation reason (was the generic 'tool error') and
  the declined call is recorded. [wenshao Suggestion]

- Session.ts startToolSpan: dual-emit the legacy call_id alias like
  CoreToolScheduler for backwards-compat dashboards. [Copilot]

* test(telemetry): cover session.id propagation, conversation_finished, tool outcome

Address wenshao's no-test-coverage CHANGES_REQUESTED on the daemon/ACP
telemetry changes.

- session-tracing.test.ts: assert tool / llm_request / tool.execution spans
  derive session.id from the owning interaction context (not the process-
  global) including a multi-session isolation case and the CLI global
  fallback.
- Session.test.ts: assert conversation_finished is emitted on the normal turn
  AND on the error/throw path (the path that previously dropped it), and that
  a soft tool failure (toolResult.error) is recorded with status 'error'.

* fix(telemetry): annotate withInteractionSpan result param to avoid implicit any

The interaction-span getResultStatus callback relied on generic inference
of T from the turn-loop return type; under the branch's pre-existing
upstream type errors that inference degrades to any, surfacing a
noImplicitAny error at the callback. Annotate the param explicitly so it
no longer depends on inference. (wenshao verification report)

* fix(telemetry): distinguish error from cancelled in interaction/tool outcomes

Address wenshao review round 2 (telemetry-accuracy suggestions).

- session-tracing.ts: extend InteractionSpanResultStatus to 'ok' | 'error' |
  'cancelled' and have withInteractionSpan's finally set SpanStatusCode.ERROR
  when getResultStatus reports 'error' on a non-throwing path. Guarded so a
  thrown error's specific message is not overwritten by the generic one.
- Session.ts #executeCronPrompt: map caught cron errors to 'error' (was
  'cancelled'), so turn_status dashboards no longer miss cron API failures.
- Session.ts runTool success path: compute aborted/status/succeeded once
  before emitResult so the client-facing success flag matches telemetry on
  abort-induced cancellation (previously emitResult used !toolResult.error).
- Session.ts runTool error paths: errorResponse and the catch-block
  recordToolResult now label aborted calls 'cancelled' instead of 'error'.

Tests: withInteractionSpan 'error' status -> span ERROR, and thrown-error
message preserved.

* refactor(web-shell): rewrite scroll-follow logic with 6 clear rules

Replace the previous scroll implementation (5 overlapping effects,
4 fragile refs, rAF-based programmaticScroll flag) with a clean,
predictable design driven by 6 documented rules:

1. Default follow-bottom on content height changes via single
   useLayoutEffect on virtualizer totalSize
2. Scroll-up pauses follow (direction detection in onScroll)
3. Scroll-back-to-bottom (< 30px) resumes follow
4. New user message forces follow on
5. Session restore: suppress scroll during catchingUp, scroll
   once on replay_complete transition
6. Short content (no scrollbar): scrollToBottom is a no-op

- Remove followBottomSignal state and handleEditorSubmit wrapper
  from App.tsx; pass connection.catchingUp to MessageList instead
- Consolidate from 5 effects to 3, from 4 refs to 3
- Add detailed block comment documenting all 6 rules and the
  implementation structure

* feat(telemetry): per-prompt traceId for bounded, renderable traces (#4661)

* feat(telemetry): per-prompt traceId — each interaction is a trace root

Previously all spans within a session shared one traceId derived from
SHA-256(sessionId). Long sessions produced unbounded traces that ARMS
and Jaeger could not render. This change makes each interaction span a
trace root with a fresh SDK-generated traceId. Cross-prompt correlation
uses the session.id span attribute (already present on interaction spans,
now stamped on all spans via SessionIdSpanProcessor).

Key changes:
- startInteractionSpan uses ROOT_CONTEXT instead of session root
- withInteractionSpan defaults to ROOT_CONTEXT when no parentContext
- SessionIdSpanProcessor stamps session.id on every exported span
- resolveParentContext / getParentContext simplified (no session root fallback)
- debugLogger falls back to deriveTraceId(sessionId) for log-line grep
- LogToSpanProcessor unchanged (naturally adapts)
- createSessionRootContext marked @deprecated

* feat(telemetry): enrich llm_request span with response metadata and error details (#4693)

Add 6 new attributes to qwen-code.llm_request OTel spans that were
previously only available in log events (ApiResponseEvent), closing
the observability gap that blocked cross-system debugging (e.g.
correlating qwen-code traces with DashScope request logs).

New span attributes (with GenAI semconv duals where applicable):
- response_id / gen_ai.response.id — provider request ID
- finish_reason / gen_ai.response.finish_reasons — model stop reason
- thoughts_token_count / gen_ai.usage.reasoning_tokens — reasoning tokens
- subagent_name — originating subagent
- error_type / error.type — structured error classification
- error_status_code — HTTP status from provider errors

Implementation details:
- Extend LLMRequestMetadata with 6 new optional fields
- Track lastFinishReason and lastError as closure variables in the
  streaming path (consolidatedResponse is try-scoped, inaccessible
  from finally)
- Capture subagentName eagerly at method entry to avoid AsyncLocalStorage

* fix(daemon): preserve parentToolCallId in compaction engine for parallel subagent streams (#4765)

* fix(daemon): preserve parentToolCallId in compaction engine for parallel subagent streams

TurnBoundaryCompactionEngine.mergeTextSlot merged all consecutive
agent_thought_chunk / agent_message_chunk events into a single slot
regardless of parentToolCallId, destroying per-subagent attribution.
When 9+ parallel subagents streamed concurrently, the compacted replay
contained garbled text with no parentToolCallId — the downstream
transcript reducer (fixed in #4689) could not route blocks to the
correct subagent tool call.

- Add parentToolCallId-aware dual-path merging: subagent chunks use an
  indexed lookup (textSlotIndex) to merge by (kind, parentToolCallId)
  even when interleaved; top-level chunks preserve the original
  consecutive-only merge to maintain text segmentation around tool calls.
- Evict textSlotIndex entries when a same-parent tool_call arrives,
  mirroring the transcript reducer's clearActiveText(parentToolCallId)
  so compacted replay block segmentation matches live behavior.
- Defensive backfill: ensure parentToolCallId survives in the compacted
  event's _meta even if the last chunk's _meta lost it.
- Harden seed() to clear in-flight state (slots, indexes, liveJournal).

* feat(daemon): optimize ACP child lifecycle — skip relaunch, preheat, idle keep-alive (#4748)

Three optimizations to reduce daemon cold start latency and improve
session throughput:

1. Skip unnecessary relaunchAppInChildProcess for ACP children by
   setting QWEN_CODE_NO_RELAUNCH=true, eliminating a redundant
   grandchild process spawn. Memory args (--max-old-space-size)
   are passed directly with container-aware cgroup detection.

2. Pre-spawn ACP child at daemon boot via bridge.preheat(), so the
   first session doesn't pay cold-start latency. Fire-and-forget
   with fallback to lazy spawn on failure.

3. Add --channel-idle-timeout-ms flag to keep ACP child alive after
   last session closes, avoiding cold restart on reconnect. Default
   0 (immediate kill) preserves backward compatibility.

* feat(telemetry): add daemon OTel metrics and structured log records

Adds 11 OTel metric instruments to the daemon serve path, covering:
- HTTP request count/latency by route and status class
- Session lifecycle (spawn/close/die) counter
- Channel lifecycle (spawn/exit) counter
- Prompt queue wait and end-to-end duration histograms
- Bridge error counter with normalized error type allowlist
- Cancel request counter
- ObservableGauges for active sessions, SSE connections, heap usage

Key design decisions:
- ObservableGauge (not UpDownCounter) for gauge-like values — immune to
  +1/-1 drift across complex lifecycle paths
- Error type normalization via allowlist (19 known types + 'unknown')
  prevents unbounded cardinality
- Explicit histogram bucket boundaries tuned for daemon latency profiles
- Bridge decoupled via BridgeTelemetry.metrics optional sub-object
- emitDaemonLog generalized with optional eventName/severityNumber
- service.instance.id added to Resource for process incarnation detection
- Pre-shutdown forceFlushMetrics for best-effort final metric export

Closes #4554 §6.

* feat(cli): enable /remember, /forget, /dream in ACP mode (#4819)

* feat(cli): enable /remember, /forget, /dream in ACP mode

These three memory-related slash commands return `submit_prompt` or
`message` action types which are fully supported by the ACP session
handler. Adding `acp` to their `supportedModes` allows web-shell
clients to invoke them via `POST /session/:id/prompt` passthrough.

Changes:
- /remember: add supportedModes (zero handler changes needed)
- /forget: add supportedModes + wrap memory manager calls in try-catch
  so filesystem/model errors surface as user-friendly messages instead
  of raw JSON-RPC errors
- /dream: add supportedModes + document that onComplete callback
  (dream metadata tracking) is not invoked in ACP mode

Known limitation: /dream's onComplete (writeDreamManualRun) is silently
skipped in ACP — the auto-dream scheduler may not know a manual dream
already ran. Accepted because eagerly calling it would record completion
before consolidation actually finishes.

Refs #4514

* fix: address wenshao review — eager writeDreamManualRun + toEqual assertions

- Call writeDreamManualRun eagerly before returning submit_prompt so
  auto-dream dedup works correctly in ACP mode (timestamp is slightly
  early but acceptable for scheduler min_hours check)
- Switch supportedModes test assertions from toContain to toEqual per
  codebase convention (catches accidental mode additions)

Refs #4514

* fix: address wenshao review round 2

- dreamCommand: add try-catch for error resilience in ACP; make eager
  writeDreamManualRun conditional on executionMode === 'acp' to avoid
  double-write in interactive mode and cancel-semantics regression
- rememberCommand: add explicit if (!config) guard (consistency with
  dream/forget; avoids silent fallthrough in ACP)
- Add config:null test for rememberCommand
- Split dream test into interactive (no eager write) vs ACP (eager write)

- ACP mode returns without onComplete (eliminates double-execution risk

- Add return value + no-onComplete assertions to ACP test

* feat(serve): add HTTP rewind endpoints for daemon/web-shell (issue #4514 T3.2)

Expose session rewind as structured HTTP API so web-shell and SDK
clients can rewind a session's conversation and files to a previous
turn without relying on TUI-only dialog interaction.

API surface:
- GET /session/:id/rewind/snapshots — list rewindable turns with diff stats
- POST /session/:id/rewind — execute file restore + conversation truncation

Leverages the existing Session.rewindToTurn() for conversation
truncation and FileHistoryService.rewind() for file restore. Extends
the existing 'rewindSession' ACP extMethod to also support promptId
parameter and file history rewind.

Error handling:
- 409 SessionBusyError when a prompt is running
- 400 InvalidRewindTargetError when the target turn is compressed or
  does not exist
- 404 SessionNotFoundError for unknown sessions

Cross-client SSE event 'session_rewound' published on success with
originatorClientId for echo suppression.

* fix(serve): use snapshot array position for turnIndex, add errorKind to format errors

Two Codex review fixes:

1. After a rewind, Session.turn remains monotonic so promptId suffixes
   no longer correspond to actual turn positions. Use the snapshot's
   index in FileHistoryService.getSnapshots() instead of parsing the
   suffix — the array is always in sync with the current conversation.

2. Format validation errors (invalid prefix, non-numeric suffix) now
   carry errorKind: 'invalid_rewind_target' so the bridge maps them
   to 400 instead of falling through to 500.

* feat(cli): enable /directory command in ACP mode

Refactor /directory (show/add) from addItem-based output to returning
MessageActionReturn so it works in ACP mode (web-shell).

Changes:
- Add supportedModes: ['interactive', 'acp'] to parent + both subcommands
- Add argumentHint to add subcommand for command palette
- Add parent action returning usage hint for bare /directory invocation
- Refactor show: return message instead of addItem
- Refactor add: collect all outputs into messages array, return single
  message (messageType: 'error' if any errors, 'info' otherwise)
- Add try-catch outer wrapper for unexpected errors
- Simplify pathsToAdd parsing (remove no-op split-join)
- Update existing .tsx tests to assert on return values instead of addItem
- Add new .ts test file with 11 tests covering ACP paths

Known limitations:
- Mixed success+error returns use messageType: 'error' for the whole
  message (single MessageActionReturn can't express mixed severity)
- Cross-session: directory add is session-scoped, other sessions see
  the change after restart (pre-existing architectural property)

* fix: address Copilot review — usage hint format and conditional QWEN.md message

1. Usage hint now shows comma-separated format: `<path>[,<path>,...]`
2. QWEN.md files success message only emitted when memory refresh actually runs

* fix: address wenshao review — partial-success warning, gemini try-catch, test consolidation

1. Use messageType 'warning' for partial success (some paths added, some failed)
   instead of 'error' which throws in ACP mode via Session.ts
2. Wrap gemini.addDirectoryContext() in its own try-catch to prevent losing
   accumulated success messages on failure
3. Consolidate duplicate .test.ts into .test.tsx, add space-in-path test,
   add settings.setValue assertion for mixed-result scenario
4. Delete redundant directoryCommand.test.ts

* fix: add missing test coverage for gemini try-catch and null-config guards

1. Add test for addDirectoryContext() rejection → messageType 'warning' + error message
2. Restore null-config tests for both show and add subcommands (lost during consolidation)

- GET /workspace/hooks — config-sourced hooks (user/project/extensions)
- GET /session/:id/hooks — runtime session hooks (skill-registered)

Wiring: status types + idle factory (acp-bridge), bridge interface +
impl, ACP agent builders + extMethod dispatch, workspace-service facade,
REST routes, capability tags, SDK types + client methods, barrel exports.
Slash command /hooks enabled for ACP mode (text output via listCommand).

status types + idle factory in acp-bridge, builder in acpAgent, workspace-
service facade, REST route, SDK client method, and capability tag.

- ServeExtensionEntry with id, name, version, isActive, capabilities
  (mcpServerCount, skillCount, etc.), redacted source URL
- /extensions slash command enabled in ACP/non_interactive mode with
  text-based list subcommand
- DaemonClient.workspaceExtensions() SDK helper
- workspace_extensions capability tag (always-on)

* fix(cli): address Copilot review on extensions list command

- Remove install hint from empty-state message (install is interactive-only)
- Cache Object.keys(ext.mcpServers) count to avoid duplicate computation

* chore: remove stale issue reference from section comment

* fix(cli): guard interactive-only extension subcommands in ACP mode

parseSlashCommand descends into subCommands without checking
supportedModes, so /extensions install and /extensions explore could
execute in ACP mode despite declaring interactive-only. Add runtime
mode guards to installAction, exploreAction, and listAction (manage
dialog) to prevent side effects in non-interactive modes.

* fix(cli): address wenshao review on extensions command

- Fix TS2322: use string literal 'info'/'error' instead of MessageType
  enum for SlashCommandActionReturn messageType field
- Wrap user-facing strings in t() for i18n consistency

* fix: rename _args to args in listAction (wenshao review)

Parameter is used — passed to listTextAction. Remove misleading
underscore-prefix convention.

* fix: resolve TS7030 inconsistent return paths in extensionsCommand

exploreAction and installAction return a message object on the
non-interactive guard but void on other paths. Add explicit
return undefined at function end to satisfy noImplicitReturns.

* fix: add try/catch around getExtensions() in listTextAction

Defensive error handling consistent with the ACP builder pattern.

* feat(serve): add /settings slash command for web-shell (#4816)

* feat(serve): add GET/POST /workspace/settings for web-shell settings dialog

Add full-stack settings CRUD across daemon API, SDK, React hooks, and
web-shell UI, closing the /settings gap tracked in #4514 T3.9.

Daemon: GET/POST /workspace/settings with showInDialog allowlist,
server-side type validation, conditional workspace_settings capability,
and settings_changed event broadcasting.

SDK: DaemonClient methods, types, event normalization
(settings_changed → workspace.settings.changed).

React: useDaemonSettings hook with event-driven reload via
settingsVersion signal in DaemonSessionProvider.

Web-Shell: SettingsDialog with category grouping, scope switching,
inline editing, sub-dialog delegation, restart notifications, and
full i18n (EN + ZH-CN).

* fix(web-shell): address Copilot review on SettingsDialog type safety

- Use explicit boolean comparison (=== true) instead of truthiness for unknown values
- Fix Number('') = 0 bug: reject empty/whitespace input before Number conversion
- Use Number.isFinite for client-side validation (matches server-side)

* chore: trigger bot re-check after PR body template update

* fix(serve): fix test drift and default value fallback in settings API

- Add workspace_settings conditional capability branch to server.test.ts
  drift-insurance test (prevents CI failure)
- Fall back to schema default when effective value is undefined in
  GET /workspace/settings (fixes first-toggle bug for default-true booleans)

* fix(serve): address wenshao review — scope restriction, restart message, and hardening

- Restrict POST /workspace/settings to workspace scope only (remove user scope)
- Fix requiresRestart message being cleared by useEffect (track restartPending state)
- Remove explicit reload() — let SSE event-driven reload handle it (fixes double reload)
- Add busyKey guard to prevent double-submit during save
- Add string max length validation (1024 chars)
- Sanitize error messages — don't leak filesystem paths in HTTP responses
- Remove corruptedPath from GET response — only return recovered boolean
- Extract shared getAllowedKeys() to deduplicate filter logic
- Replace scopeToEnum with explicit SCOPE_MAP
- Separate persist and broadcast try/catch blocks
- Add settings_changed case to asKnownDaemonEvent and reducer
- Add workspace_settings to EXPECTED_REGISTERED_FEATURES test array

* fix(serve): address wenshao review round 2

- Define DaemonSettingsChangedEvent type and add to KnownDaemonEvent union
- Add workspace.settings.changed case to terminal.ts and transcript.ts exhaustive switches
- Move restartPending useState declaration before useEffect that references it
- Fix scope error message to match VALID_WRITE_SCOPES contents

* refactor(serve): simplify settings code per review agents

- formatValue now calls resolveValue instead of duplicating scope lookup
- Collapse intermediate groups memo into single rows memo
- Pass cached allowedKeys to buildSettingsResponse (avoid per-GET recomputation)
- Remove dead user entry from SCOPE_MAP (only workspace is accepted)

* fix(serve): align workspace_settings position in EXPECTED_REGISTERED_FEATURES

Move workspace_settings to match its registry declaration order (after
workspace_tool_toggle, before workspace_init). Filter and re-insert
workspace_init, workspace_mcp_restart, session_recap, session_btw to
maintain Object.keys order alignment.

* fix(serve): address wenshao R3 review — scope guard, restartPending reset, error context

- Disable editing in user scope (handleAction returns early when scope !== 'workspace')
- Reset restartPending at start of handleSetValue to allow message auto-clear
- Add key/scope/workspace context to persist and broadcast error logs
- Replace SCOPE_MAP[scope]! non-null assertion with explicit guard

* fix(serve): address wenshao R4 review — scope type, edit click guard, bundle limit

- Narrow SDK scope type to 'workspace' only (server rejects 'user')
- Guard handleAction against clicks during edit mode (prevents data loss)
- Dismiss editMode when clicking a different setting row
- Bump MAX_DAEMON_BROWSER_BUNDLE_BYTES to 107*1024 for new exports

* fix(serve): address wenshao R5 — actions.ts scope type, selectedIdx init

- Narrow actions.ts setWorkspaceSetting scope to 'workspace' (missed in R4)
- Initialize selectedIdx to 0 instead of 1 for empty-settings safety

* fix(web-shell): show read-only message when acting in user scope

Addresses R5 suggestion: Tab-toggled user scope silently no-ops on
action attempts. Now shows "User-scope settings are read-only" message.

* fix(web-shell): address wenshao R6 — scope type literal, restartPending preservation

- Pass literal 'workspace' to setValue (fixes tsc build failure)
- Only clear restartPending/message when new save doesn't require restart

* fix(web-shell): address R7+R8 review — restartPending, busyKey click guard, selectedIdx

- Remove else-branch that unconditionally cleared restartPending when
  saving a non-restart setting (R7 Critical)
- Add busyKey guard to onClick handler matching keyboard handler (R7)
- Fix selectedIdx=0 highlighting category header on mount — effect now
  advances to first setting row (R7)
- Use ref for selectedIdx in useDelayedGlobalKeyDown to avoid
  re-registering listener on every arrow key press (R8)
- Bump MAX_DAEMON_BROWSER_BUNDLE_BYTES to 112*1024 with margin (R8 Critical)

* fix(serve): address post-approval suggestions — editMode stuck, type cast, approvalMode deny-set

- Clear editMode when setting disappears from rows during SSE reload
- Use isRecord guard instead of unsafe type cast in normalizeSettingsChanged
- Add SECURITY_SENSITIVE_SETTINGS deny-set to block tools.approvalMode
  from generic write path (must go through trust-gated session route)
- Remove tools.approvalMode from SUB_DIALOG_KEYS (no longer in list)

* fix(daemon): enable auto-title generation for ACP (daemon) sessions (#4836)

The automatic session title generation was silently disabled for all
daemon sessions. The guard in `maybeTriggerAutoTitle` checks
`config.isInteractive()`, which returns false for the ACP child process
because it is spawned with pipe stdio (`process.stdin.isTTY === false`).

This guard was originally added to prevent headless one-shot CLI runs
(`qwen -p "do something"`) from wasting fast-model tokens on a title
that no one would ever see. However, daemon sessions are long-lived and
user-resumable — they appear in the session list and benefit from
semantically meaningful titles.

The fix allows ACP mode (`config.getExperimentalZedIntegration()`) to
bypass the `isInteractive()` check while still blocking true headless
CLI runs. After this change, the first assistant reply in a daemon
session will trigger LLM-based title generation (3-7 words, sentence
case) using the configured fast model, just as it does for interactive
TUI sessions.

Adds a dedicated HTTP route that forks a live session's JSONL transcript
and loads the fork via resume semantics (no history replay). Remote
clients can now programmatically branch sessions without the interactive
dialog the CLI /branch command requires.

Key design decisions:
- Uses resume (not load) to avoid flooding SSE with full history replay
- Source session must be idle (409 if prompt active via `promptActive` flag)
- ACP extMethod pattern for the fork operation (flush + forkSession + title)
- Validates originator via resolveTrustedClientId before event emission
- Cross-client events on source bus + workspace-wide fan-out
- Extracts computeUniqueBranchTitle to core for reuse

* feat(daemon): add POST /session/:id/language for runtime language switching (#4705)

* feat(daemon): add POST /session/:id/language for runtime language switching

Add a dedicated HTTP endpoint for switching UI language and LLM output
language without polluting the session transcript. The endpoint flows
through three layers (server route → bridge → ACP extMethod handler)
following the same pattern as approval-mode and model switching.

When syncOutputLanguage is true, the handler updates output-language.md,
persists settings, and refreshes system prompts across all active
sessions so the next LLM call immediately uses the new language.

* fix(daemon): persist original language param to preserve auto-detection

When language is "auto", persist the literal "auto" to settings instead

detectSystemLanguage() is re-evaluated on daemon restart rather than

* feat(daemon): keep model & approval-mode state consistent across clients sharing a session (#4613)

* feat(daemon): bridge side-channel state layer — A1 follow-up + A2 + A5 (#4511)

* fix(daemon): address review on side-channel state consistency

- inject session_snapshot up front on fresh SSE connections (not only on resume)
- reconcile only after a roundtrip that landed; guard generation TOCTOU with
  one bounded re-run and log skip/correct/fail transitions
- drop unencodable reconciliation_failed bus event in favor of operator log
  (client path already covered by state_resync_required)
- bridgeClient mode fallback emits previous/persisted; dual-emit session_update
  uses the canonical nested data.update shape
- validate modeId at the setMode boundary; reject unknown modes
- SDK session_snapshot validator type-checks currentModelId/currentApprovalMode
- tests: fresh-connection snapshot + reconciliation drift/match/failure/roundtrip-failure

* fix(daemon): address second-round review on side-channel state layer

- applyModelServiceId: gate reconcile behind a `succeeded` flag so a
  rejected create/attach-time roundtrip can't pair a corrective
  model_switched with the model_switch_failed it just published; mirrors
  setSessionModel / setSessionApprovalMode.
- in-session mode demux: validate currentModeId against the known
  approval-mode enum (lockstep with Session.setMode) before it fans out
  to SSE clients / the SDK reducer.
- in-session mode demux: suppress the legacy session_update dual-emit on
  the exit_plan_mode path via a `legacyFrameSent` flag — sendUpdate
  already published that frame, so dual-emitting delivered it twice. The
  setMode path (no sendUpdate) keeps its dual-emit.
- reconcile: emit a `reason=roundtrip_failed` skip log on all three
  failure paths so the skipped reconcile is greppable.
- SDK: add session_snapshot to RESYNC_PASSTHROUGH_TYPES so a client that
  reconnects past ring eviction recovers currentModelId / approvalMode
  from the full-state frame instead of staying stale until loadSession.
- tests: approvalMode reconcile drift + roundtrip-fail, generation rerun,
  unknown-mode enum drop, dual-emit shape + suppression, setMode
  extNotification + unknown-modeId rejection.

* fix(daemon): stamp serverTimestamp at EventBus and fix streaming state finalization (#4855)

* fix(daemon): stamp serverTimestamp at EventBus and fix streaming state finalization

Two issues fixed:

1. Blocks missing serverTimestamp: previously serverTimestamp was only
   stamped at the SSE write boundary (formatSseFrame), so events fetched
   via load/replay had no timestamp. Move the stamp to EventBus.publish()
   so all consumers share the same server clock. SSE layer retains a
   fallback for synthetic frames that bypass EventBus. CompactionEngine
   preserves envelope _meta through text chunk merging. Normalizer adds
   a 4th probe location for ACP update._meta.timestamp.

2. Streaming display errors: when switching text block types (e.g.
   thought → assistant), the old block's streaming flag was not set to
   false. Extract unified clearActive{Assistant,Thought}{,ForParent}
   helpers that finalize the old block before clearing the active pointer.
   Also set streaming=true for thought blocks (previously only assistant),
   and emit assistant.done during replay snapshot turn boundaries so
   historical turns render as completed.

* feat(web-shell): make bottom-left mode indicator mouse-selectable (#4874)

* feat(web-shell): make bottom-left mode indicator mouse-selectable

The approval-mode indicator in the status bar could only be switched
with shift+tab. Make the mode label a button that opens the existing
ApprovalModeMessage picker (which already supports per-row mouse
selection), so the mode can be chosen with the mouse too.

- StatusBar: render the mode label as a <button> when an onSelectMode
  callback is provided; falls back to the original spans otherwise.
- App: wire onSelectMode to open the approval-mode picker inline.
- Update the hint text + add a click affordance (cursor, hover, title).

* fix(web-shell): close approval-mode picker on outside mouse press

The inline approval-mode picker has no modal backdrop, so a mouse press
outside it did not dismiss it. Listen for document mousedown and close
when the press lands outside the panel (Esc / row-select still work).

* refactor(web-shell): address review on mode-indicator click

- StatusBar: make onSelectMode required and always render the mode
  indicator as a <button>, so the "click to switch" hint is never shown
  on a non-interactive label (drops the dead backward-compat branch).
- MessageList: when an inline picker (tailContent) first appears, force
  auto-follow and scroll it into view, so opening it while scrolled up
  no longer looks like a no-op (covers mouse, Shift+Tab, slash command).

* feat(web-shell): wrap arrow-key navigation in approval-mode picker

ArrowUp/ArrowDown now wrap around (last→first, first→last) instead of
clamping at the ends, matching the existing ModelMessage picker.

* fix(web-shell): only dismiss approval picker on primary mouse button

The outside-press handler fired for any button, so right-click (context
menu) and middle-click (X11 paste) also closed the picker. Ignore
non-primary buttons (event.button !== 0).

* fix(web-shell): address maintainer review on mode-indicator UX

Three blocking items from @chiga0:

1. default mode is now mouse-operable — getModeIndicator returns an
   indicator for `default` (using the existing mode.default string), so
   the status-bar control is a clickable button in every known mode; the
   "? for shortcuts" fallback only remains for the unknown/disconnected
   state.
2. the status-bar trigger is now a real toggle (setApprovalModeInlineOpen
   flips), and stopPropagation on its mousedown stops it from counting as
   an outside press for the picker's dismiss handler — so it can never
   close-then-reopen.
3. the scroll-into-view-on-open behavior is now opt-in via a new
   MessageList `autoScrollTailIntoView` prop, passed only for the
   approval-mode picker; model/agents/memory panels keep scroll position.

* polish(web-shell): address ytahdn review on mode picker

- ApprovalModeMessage: dismiss on touchstart too (tap-outside on touch
  devices) and skip when the press was already defaultPrevented.
- MessageList: re-check shouldFollow inside the rAF so a scroll-up during
  the frame gap doesn't get fought by the tail reveal.
- StatusBar: add aria-haspopup="listbox" so the trigger announces it opens
  a picker.

* fix(web-shell): close touch close-then-reopen + honest listbox a11y

- StatusBar: stopPropagation on the trigger's touchstart too (not just
  mousedown), so tapping it never counts as an outside press for the
  picker's dismiss handler — mirrors the desktop fix for the touch path
  added in 1ef1144.
- ApprovalModeMessage: mark the list as role="listbox" and rows as
  role="option" + aria-selected, so the trigger's aria-haspopup="listbox"
  matches real semantics.

The model label in the status bar could only be changed via the /model

model label a button that opens the existing ModelMessage picker, so the
model can be chosen with the mouse.

- StatusBar: render the model label as a <button> (tooltip, hover
  affordance — the name brightens + underlines, aria-haspopup="listbox").
  stopPropagation on mousedown/touchstart so the opening press is not
  treated as an outside press by the picker's own dismiss handler.
- App: wire onSelectModel to toggle the inline model picker, and let the
  picker reveal itself (autoScrollTailIntoView) like the mode picker.
- ModelMessage: dismiss on outside press (mouse/touch); add listbox/option
  roles + aria-selected; highlight rows on hover via CSS (.row:hover)

* feat(serve): add cursor-based pagination for session list

The ACP protocol defines cursor/nextCursor on ListSessionsRequest/
ListSessionsResponse, and the internal SessionService already supports

layers:

- REST GET /workspace/:id/sessions now accepts ?cursor=<mtime>&size=<n>
  query params and returns { sessions, nextCursor?, hasMore }
- ACP HTTP dispatch session/list now reads params.cursor and returns
  nextCursor in the response, matching the ACP protocol spec
- Live (in-memory) sessions are merged only on the first page (no
  cursor) since they are always the most recent
- Default page size: 20, max: 100

- render "(Modified in X)" / "(Also modified in X)" inline after the
  setting label (same row, secondary color), matching the native CLI's
  getScopeMessageForSetting() — the earlier removal dropped the info
  entirely instead of just the extra row
- export nextSettingIdx and cover wrap-around, header skipping, empty
  list, and normalization entry points with unit tests

* feat(daemon): add POST /workspace/reload-env for hot-reloading env vars and session auth (#4924)

* feat(daemon): add POST /workspace/reload-env for hot-reloading env vars and session auth

Add a new daemon endpoint that reloads environment variables from .env
files and settings.env without restarting the daemon, and refreshes
auth on all idle sessions so both new and existing sessions immediately
use updated credentials (e.g. API keys).

Core changes:
- settings.ts: reloadEnvironment() with file-snapshot-based deletion
  tracking (lastReloadSnapshot seeded at boot), RELOAD_EXCLUDED_KEYS
  safety list, and force-write semantics for explicit reload
- Session.ts: isIdle() method with cancel-race protection via
  pendingPromptCompletion null-reset
- acpAgent.ts: workspaceReloadEnv extMethod handler with
  Promise.allSettled session refresh, modelProviders reload, and
  skipLoadEnvironment to preserve diff accuracy
- workspace-service: EnvReloadResult/Response types, facade with 30s
  timeout and best-effort child forwarding
- server.ts: POST /workspace/reload-env route behind strict mutation gate
- capabilities.ts: conditional workspace_reload_env capability
- SDK: env_reloaded event type, DaemonClient.reloadEnv(), barrel exports

1. SessionNotFoundError now reported as childError instead of silently

2. Remove duplicate EnvReloadResult — types.ts re-exports from settings.ts
3. Move pendingPrompt=null to finally block — prevents isIdle() from
   returning false permanently if #executePrompt throws
4. Skip deletion pass when .env file read fails — transient I/O failure

* feat(daemon): session idle reaper for automatic cleanup (#4833)

* feat(daemon): add session idle reaper for automatic cleanup of disconnected sessions

Idle sessions accumulate when clients close browser tabs or crash without
calling DELETE /session. Without cleanup, sessions leak memory (EventBus
ring ~2-4 MB each) and eventually hit the maxSessions cap (default 20),
locking out new sessions entirely.

Add a configurable session reaper that periodically scans the in-memory
session registry and closes sessions that have no SSE subscribers, no
registered clients, no active prompt, and whose last heartbeat exceeds
a configurable idle TTL (default 30 minutes).

Key design decisions:
- Uses existing closeSession path (soft close, not hard kill)
- JSONL transcripts on disk are preserved — session/load or session/resume
  can restore any reaped session
- Emits session_closed with reason 'idle_timeout' so clients can distinguish
  from explicit closes
- Reaper timer is .unref()'d and stopped on shutdown/killAllSync
- Configurable via --session-reap-interval-ms and --session-idle-timeout-ms
  CLI flags (0 = disabled)

* feat(daemon): close session on last client detach + fix reaper idle predicate

Add close-on-last-detach to detachClient: when clientIds.size drops to 0
AND no SSE subscribers remain, call closeSessionImpl immediately. This
handles the normal tab-close path without waiting for the idle reaper.

Adjust the idle reaper to NOT check clientIds.size — it now serves as a
backstop for the crash path where detach was never sent (clientIds still
> 0 but no subscriber and no heartbeat).

Add SessionEntry.promptActive boolean flag to reliably detect active
prompts regardless of whether an originator clientId was provided,
fixing a gap where headless prompts (no clientId context) were invisible
to the reaper's activePromptOriginatorClientId check.

Update existing heartbeat detach test to use two clients (single-client
detach now triggers close-on-last-detach). Add 3 close-on-last-detach
tests.

* feat(web-shell): make context usage mouse-reachable and survive reloads (#4958)

* feat(web-shell): make context usage mouse-reachable

The status-bar percentage and the /context panel's detail hint could
only be exercised by typing slash commands. Mirror #4887:

- StatusBar: the "x.x% context used" label is now a button that runs
  the same flow as typing /context (echo + usage panel). No
  stopPropagation: it opens no picker, so a press should dismiss any
  open picker like any other outside press.
- ContextUsageMessage: the "/context detail" literal inside the hint
  line is now a button that runs /context detail. Located by literal
  match in the translated hint so translations without it degrade to
  plain text. Callback travels App -> MessageList -> MessageItem ->
  SystemMessage with stable identity to keep memoization intact.
- App: extract showContextUsage() shared by the /context slash command
  and both buttons, so click and typed behavior cannot drift.

* fix(webui): seed tokenCount from replay snapshot on session attach

tokenCount was only populated from streaming usage updates and reset
to 0 on attach, so the status-bar context indicator vanished on every
page reload until the next model response.

Scan the freshly loaded replay snapshot backwards for the latest
usage-bearing session_update and seed the connection with it (turn
compaction keeps each merged slot's last _meta, so usage survives).
Only populated when this attempt actually (re)loaded the session: a
reused session object carries the snapshot from its original load,
whose usage may be older than the in-memory count. Malformed replay
events are skipped per-event, mirroring the injection loop.

* test(webui): cover getReplayTokenCount edges and tokenCount fallbacks

Review follow-up on #4958: the seeding test only covered the
replay-hit branch.

- mappers.test.ts: empty array, usage-less replay, latest-wins,
  inputTokens precedence + totalTokens fallback, non-positive and
  non-numeric filtering, null payloads, and throwing payload getters.
- provider: SSE re-subscribe on the same session keeps the in-memory
  count (the reused object's stale empty snapshot must not reset it);
  attaching a different session without replay usage resets to 0.

* feat(web-shell): make /settings mouse-reachable via a status-bar gear icon (#4972)

Add a gear button at the far left of the status bar, before the
approval-mode indicator. Clicking it toggles the same inline /settings
panel as typing /settings; clicking again, pressing outside, or Escape
closes it.

- Same stopPropagation contract as the mode button: the settings panel
  dismisses on outside mousedown/touchstart, so the opening press must
  not reach the window or the gear could never toggle the panel closed.
- settingsInlineOpen joins autoScrollTailIntoView so the panel reveals
  itself when opened from the status bar while scrolled up.
- The gear is absolutely positioned in the bar's 2ch left-padding
  gutter (plus 6px of the footer margin): it takes no flex space, so
  the mode label keeps its input-text alignment, with a visible gap on
  both sides of the icon.
- Hidden while disconnected like the other status-bar controls (the
  panel needs the daemon to load settings); tooltip/aria-label reuse
  the existing settings.title i18n key.

* fix(web-shell): merge adjacent tool calls into one tool_group like native CLI (#4975)

* fix(web-shell): merge adjacent tool calls into one tool_group like native CLI

Native CLI batches every tool call of one scheduler turn into a single
bordered tool_group (mapToDisplay), but the web-shell adapter created a
separate single-tool group per daemon tool block, so parallel tool calls
rendered as N separate boxes.

Merge a tool block into the trailing tool_group when nothing visible
separates them. Sub-agent calls keep their own single-tool groups so
ParallelAgentsGroup still detects consecutive agent launches, and
synthetic raw-shell groups (bare block id, no tg- prefix) never absorb
real tool calls.

* fix(web-shell): route raw shell chunks to the running execute tool in merged groups

Shell transcript blocks carry no toolCallId; the handler previously
appended chunks to the last tool of the last group. With adjacent-merge
a group can now hold e.g. [Bash, Read], so prefer the most recent
in-progress execute tool, then the most recent execute tool, then the
last tool (old behavior) when picking the attachment target.

* feat(web-shell): collapse thinking output to a 5-line window (#4977)

* fix(build): complete the 0610 origin/main merge left half-applied

The 0610 merge (44b936b73) brought in main's test mock + import of
createSessionRootContext but kept the old refreshSessionContext
implementation and assertions, leaving a dead import that fails
tsc under noUnusedLocals. Align both impl and tests with main.

The same merge also missed the branch-only IDLE_HOOK_EVENTS table
when main added UserPromptExpansion / InstructionsLoaded to
HookEventName: add the two entries (matcher kinds per hookPlanner
semantics) and extend ServeHookMatcherKind plus the SDK mirror
types so the daemon<->SDK contract stays in sync.

Fixes 'npm run dev:daemon' startup (stale acp-bridge dist could
not be rebuilt because the workspace build was broken).

* feat(web-shell): collapse thinking output to a 5-line window

Long thinking output flooded the screen. The compactThinking
customization existed since #4867 but was never enabled for the
standalone shell, and sub-agent thought streams (the bulk of the
output under /review-style skills) had no collapse at all.

- Enable compactThinking for the standalone web shell (main.tsx);
  the embedder API default stays opt-in.
- While thinking streams, the collapsed preview now follows the
  tail (newest lines pinned into view) instead of freezing on the
  first five lines; switches back to head-clamp + expand toggle
  when the stream ends.
- Collapse running sub-agent streams in SubAgentPanel to the same
  5-line tail window with an expand/collapse toggle; the full
  400px scroll view remains one click away. Completed-agent
  details keep the existing click-to-open behavior.
- Re-check overflow on content growth: the clamped box stops
  resizing at 5 lines, so a ResizeObserver alone missed overflow
  that arrives later (expand toggle could fail to appear).

* fix(serve): isolate per-session stats in daemon mode (#4954)

* fix(serve): isolate per-session stats in daemon mode

GET /session/:id/stats was returning process-wide cumulative metrics
instead of per-session data because uiTelemetryService is a singleton.
In daemon mode multiple sessions share the same process, causing stats
to bleed across sessions.

Add per-session metrics isolation via dual-write pattern:
- addEvent(event, sessionId?) routes events to both the global metrics
  (backward compat for CLI) and a per-session Map bucket
- getMetricsForSession(sessionId) returns isolated session data
- removeSession(sessionId) cleans up on session close and prevents
  late-arriving events from recreating the bucket via closedSessions Set
- resetSession(sessionId) supports session resume without wiping other
  sessions (replaces global reset() in daemon context)
- Replay path (replayUiTelemetryFromConversation) passes sessionId so
  resumed sessions correctly populate their per-session bucket

All telemetry dispatch points (loggers.ts, suggestionGenerator.ts)
now pass config.getSessionId() to addEvent for session attribution.

* fix: cap #closedSessions Set + add replay test (wenshao review)

- Bound #closedSessions to 1000 entries, evicting oldest on overflow
- Add test verifying resetSession does not clear global metrics
- Add test verifying #closedSessions cap allows evicted sessions to
  accept new events

* fix: update test assertions for addEvent sessionId parameter

loggers.test.ts: 6 toHaveBeenCalledWith assertions now expect the
second sessionId argument ('test-session-id').
client.test.ts: add resetSession to mockUiTelemetryService so
replayUiTelemetryFromConversation doesn't throw on the mock.

* fix: reset lastPromptTokenCount on session resume (wenshao Critical)

resetSession(sessionId) didn't clear the global lastPromptTokenCount
and lastCachedContentTokenCount scalars, unlike reset(). A stale high
value from a previous session could cause premature auto-compaction
on a freshly resumed conversation.

* fix: remove global scalar resets from per-session branch + reset() clears session state

- sessionService.ts: remove setLastPromptTokenCount(0) and
  setLastCachedContentTokenCount(0) from per-session branch — these
  are global scalars that contaminate other sessions
- uiTelemetry.ts: reset() now clears sessionMetrics and closedSessions

* fix(daemon): bind QWEN_CODE_SESSION_ID to the current session via AsyncLocalStorage (#4998)

* test(telemetry): add missing createSessionRootContext import in sdk.test.ts

tsc --build fails on daemon_mode_b_main because sdk.test.ts references

* fix(daemon): bind QWEN_CODE_SESSION_ID to the current session via AsyncLocalStorage

In daemon mode one process hosts many sessions, but the shell context
env session ID was read from process.env — a single process-global slot
that only the FIRST Config ever claims (sessionEnvClaimed guard in
config.ts). Every later session (new or resumed) spawned shells that
reported the first session's ID, mismatching the actual session.

- add sessionIdContext (AsyncLocalStorage), mirroring promptIdContext
- getShellContextEnvVars(): prefer sessionIdContext over process.env;
  fall back to process.env so single-session CLI behavior is unchanged
- ACP Session: wrap #executePrompt / #executeCronPrompt /
  #executeBackgroundNotificationPrompt in sessionIdContext.run(...)
- tests: ALS precedence, env fallback, concurrent-session isolation

* fix(daemon): language switch writes to wrong output-language.md path (#4938)

* fix(daemon): language switch writes to wrong output-language.md path

## Problem

`POST /session/:id/language` (PR #4705) always writes `output-language.md`
to the global `~/.qwen/` path, but `Config.outputLanguageFilePath` may
point to a project-level `<cwd>/.qwen/output-language.md` (when it existed
at startup). Since `refreshHierarchicalMemory` reads from the Config-bound
path, the language switch silently fails when a project-level file exists.

Additionally, on a fresh environment where no `output-language.md` exists,
the first language switch creates the file but `Config.outputLanguageFilePath`
remains `undefined` (readonly), so `refreshHierarchicalMemory` never reads
the newly created file.

## Fix

1. **Config.outputLanguageFilePath**: remove `readonly`, add
   `setOutputLanguageFilePath()` so the path can be registered after
   first-time file creation.

2. **languageUtils.ts**: add optional `targetPath` parameter to
   `writeOutputLanguageFile()` and `updateOutputLanguageFile()`. Export
   `getOutputLanguageFilePath()` for callers that need the global default.

3. **acpAgent.ts**: write to the session Config's actual path. On first-time
   creation (path was undefined), register the global path on Config. On
   multi-session refresh, also update each session's own file if its path
   differs from the one already written.

4. **languageCommand.ts** and **SettingsDialog.tsx**: same Config-bound
   path fix for the CLI `/language` command and settings dialog.

5. **server.ts**: expose `supportedLanguages` array in `GET /capabilities`
   so clients can discover valid language codes before calling the endpoint.

6. **SDK**: add `DaemonClient.setSessionLanguage()` method and

* feat(daemon): add POST /workspace/reload for unified settings hot-reload (#4965)

* feat(daemon): add POST /workspace/reload for unified settings hot-reload

Add a single daemon endpoint that hot-reloads ALL settings (env vars,
model, approval mode, permissions, disabled tools, memory) to all
idle sessions. Replaces the narrower POST /workspace/reload-env.

Core changes:
- settings.ts: reloadEnvironment() with file-snapshot deletion tracking,
  RELOAD_EXCLUDED_KEYS safety list, dotEnvReadFailed guard
- Session.ts: isIdle() with 6-field check including notification state
  and pendingPromptCompletion null-reset
- acpAgent.ts: workspaceReload handler with settings diff detection
  (diffSettingsKeys), conditional per-field refresh, correct ordering
  (permissions before approval mode, switchModel skips redundant
  refreshAuth), APPROVAL_MODES validation
- workspace-service: ReloadResponse type, reload() facade with daemon
  env sync, 30s timeout, SessionNotFoundError reporting
- server.ts: POST /workspace/reload route behind strict mutation gate
- capabilities.ts: workspace_reload conditional capability
- SDK: settings_reloaded event type, DaemonClient.reload(), barrel exports

* fix(daemon): fix env-only reload and remove type-mismatched permission sync

1. Add envChanged flag so .env-only changes (no settings.json diff)
   still trigger refreshAuth on idle sessions
2. Remove updatePersistentRules call — settings permissions.allow is
   string[] but updatePersistentRules expects PermissionRule[]. Defer
   permission rule sync to v2.

- Merge two consecutive if(changed.has('tools')) blocks into one

* fix(daemon): wrap switchModel in try-catch for reload resilience

Consistent with setApprovalMode handling — prevents model switch
failure from skipping subsequent refreshHierarchicalMemory and
refreshSystemInstruction calls.

* fix(daemon): wrap refreshAuth in try-catch and log session reload failures

- refreshAuth can throw on network errors/invalid credentials; wrap in
  try-catch like switchModel and setApprovalMode for consistency
- Log rejection reason when a session reload fails via Promise.allSettled

* fix(daemon): SSE event parity, error logging, and reloadDaemonEnv guard

* feat(serve): add cursor-based pagination for session list

The ACP protocol defines cursor/nextCursor on ListSessionsRequest/
ListSessionsResponse, and the internal SessionService already supports
cursor-based pagination. Wire pagination through to both transport
layers:

- REST GET /workspace/:id/sessions now accepts ?cursor=<mtime>&size=<n>
  query params and returns { sessions, nextCursor?, hasMore }
- ACP HTTP dispatch session/list now reads params.cursor and returns
  nextCursor in the response, matching the ACP protocol spec
- Live (in-memory) sessions are merged only on the first page (no
  cursor) since they are always the most recent
- Default page size: 20, max: 100

* feat(serve): add TransportStream + WsStream (WebSocket transport prep)

* feat(serve): complete ACP WebSocket transport implementation

Per ACP Streamable HTTP RFD: GET /acp with Upgrade: websocket → 101 →
full-duplex WebSocket. Coexists with SSE — clients choose transport.

Implementation:
- index.ts: WS upgrade handler with bearer auth (401/403 before upgrade),
  initialize as first message, lazy session stream attachment, full
  JSON-RPC dispatch through existing transport-agnostic AcpDispatcher
- connectionRegistry.ts: SseStream → TransportStream type widening
- server.ts: store acpHandle in app.locals, pass token

* feat(web-shell): add expand toggle to shell tool output

Long shell output was clamped to a fixed 5-line tail preview
('... first N lines hidden ...') with no way to see the rest,
unlike Read output which already had a show-all toggle. The
per-line 150-char truncation from #4952 had the same gap: a
long line was cut with no way to see its full content.

Add a toggle to ExpandedBashOutput: the collapsed default keeps
the CLI-style 5-line tail with per-line truncation; a 'Show all
(N lines)' button reveals the full untruncated output (scrolling
within the existing 400px max-height) and 'Show less' collapses
it back. The button appears when either dimension hid content
(line count or line length). Reuses the existing expandBtn style
and tool.showAll / tool.showLess i18n keys.

* fix(web-shell): address review feedback on shell output toggle

- Use a distinct 'Show full lines' label when only the per-line
  150-char truncation hid content (all lines already visible), so
  'Show all (N lines)' no longer overstates what expanding does.
- Add aria-expanded to the expand/collapse buttons (bash + read)
  so assistive technology can announce the toggle state, matching
  SubAgentPanel and AssistantMessage.
- Add render tests for the toggle: short output (no button), long
  output expand/collapse round-trip, char-truncated-only expand,
  and aria-expanded state.

* fix(tui): make thinking output transient

* feat(tui): collapsible thinking blocks with duration timer

Replace the transient single-line thinking preview with a collapsible
history block that streams reasoning above the answer and collapses on
completion.

Display states:
- Streaming: fixed-height (4 visual lines) tail-scrolling window with
  pre-wrapped text and live duration counter (e.g. "∴ Thinking… 8s")
- Committed collapsed: "∴ Thinking 15s (ctrl+o to expand)"
- Committed expanded (Ctrl+O): full reasoning as dimmed markdown

Implementation:
- Track pendingThoughtItem in useGeminiStream, commit to history on
  Content/ToolCallRequest/Finished/Cancel/Error transitions
- Pre-wrap text via stringWidth for pixel-accurate visual line counting,
  ensuring perfectly stable display height during streaming
- Record thinking duration (thoughtStartTimeRef) and attach durationMs
  to committed history items
- Remove thinkingDisplayMode setting and thinkingDisplayMode.ts utility
- Clean up LoadingIndicator: remove thought preview, show only phrase +
  timer + tokens + cancel

implemented. The expand/collapse rendering code is preserved.

* fix(tui): address review findings for thinking blocks

- Remove gemini_thought from isHiddenInCompact so collapsed thinking
  lines remain visible in compact mode
- Hardcode expanded={false} since Ctrl+O expansion is deferred
- Add commitPendingThought to inner finally block to prevent orphaned
  thinking on stream exceptions
- Non-continuation Retry: commit (not discard) pending thought, add
  setThought(null) to clear stale state
- Reset thoughtBuffer after commitPendingThought in Content and
  ToolCallRequest handlers for multi-phase reasoning correctness
- Optimize tailVisualLines: process only tail slice, use
  getCachedStringWidth for ASCII fast-path
- Fix 4 test assertions to expect pendingThoughtItem in
  pendingHistoryItems

* fix(tui): clamp streaming thinking lines to terminal height

On short terminals, the hardcoded 4-line thinking window could crowd
out the answer area. Now dynamically clamp to availableTerminalHeight/3
(min 1 line) so thinking never takes more than a third of the viewport.

* fix(tui): regenerate settings schema to remove orphaned thinkingDisplayMode

The settings.schema.json still contained the thinkingDisplayMode entry
after the setting was removed from settingsSchema.ts. Regenerate to
sync.

* test(tui): add positive tests for commitPendingThought

Verify that commitPendingThought calls addItem with the correct
gemini_thought content and durationMs at each transition point:
Finished, Content, UserCancelled, and Error.

* fix(tui): animate thinking spinner during streaming

Use ink-spinner (dots type) for the thinking header during streaming,
matching the Gemini CLI animated braille dots pattern. Committed
(collapsed/expanded) states keep a static ⠏ icon.

* fix(tui): remove static icon from committed thinking blocks

Drop the ⠏ prefix from collapsed and expanded thinking labels.
Only the streaming state shows the animated spinner.

* fix(tui): clear thought state after flush to prevent stale title

Move setThought(null) after flushBufferedStreamEvents() in Content
and ToolCallRequest handlers. Previously the flush re-invoked
mergeThought which undid the clear, leaving a stale thinking subject
in the terminal title during answer streaming.

Also add TODO comment for expanded={false} deferral.

* fix(ci): remove .qwen/design/ whitelist from gitignore

The install-script test asserts that internal planning documents are
not whitelisted in .gitignore. Remove the !.qwen/design/ entries and
untrack the design doc.

* fix(tui): use ✦ (U+2726) icon for thinking header

Switch from ✧ (hollow) to ✦ (solid four pointed star) for better
visual weight matching with surrounding text.

* fix(tui): unconditionally clear thought state in commitPendingThought

Move setPendingThoughtItem(null) and thoughtStartTimeRef reset outside
the if-guard so stale reasoning is cleared even when the ref is null
but React state hasn't flushed yet (e.g. non-continuation retry
render cycle lag).

* test(tui): add commitPendingThought tests for ToolCallRequest and Retry paths

Add two positive tests covering thought-to-history commitment at the
ToolCallRequest and non-continuation Retry transitions — the two paths
that were previously untested.
