8e266797a8 perf: improve harness context efficiency (#838)
* Improve harness context efficiency

* Address harness efficiency review findings

* Make recaps idle and cancellable

Delay recap generation until the session has been inactive, orient it around the active goal and next task, cancel stale work on activity, and render the result ephemerally above the composer.

Also strengthen the formatter safety regression to exercise formatter-modified edit output.

* Track every replace-all edit span

Translate each replacement into its post-edit line range, including cumulative shifts from earlier replacements, so follow-up edits remain authorized for every model-supplied change.

* Make review regressions cross-platform

Verify replace-all tracking through the canonical edit tool path instead of a platform-sensitive temp path, and cover cancellation when recaps are disabled during generation.

* fix(tools): derive SeenWhole from the recorded ranges

SeenWhole was a flag set only by a SINGLE read covering the file, while
SeenRange judged coverage from the accumulated ranges. The two then
disagreed about identical reads: after reading lines 1-50 and 51-100 of a
100-line file, SeenRange(1,100) was true and SeenWhole was false.

That matters because write_file gates overwrites on SeenWhole. A file past
the read byte budget cannot be read whole in one call — the read is
truncated and RecordSeenRange is correctly skipped, since the model did not
see those lines — so no sequence of reads could ever set the flag, and the
overwrite was refused permanently with:

    the intended change depends on content that has not been read exactly
    in this session. Read the affected lines with read_file, then retry.

Advice that could not change the answer. edit_file was unaffected because it
gates on SeenRange, so the escape was to edit rather than rewrite, but a
model following the error text would loop.

SeenWhole is now computed from the ranges against the file's recorded line
count, so scoped reads that together cover a file make it writable and the
error text becomes actionable. The observation carries that line count, and
a read reporting a different one clears the accumulated ranges: they
describe a shape the file no longer has.

Coverage is judged by merging sorted ranges rather than walking every line
against every range, which the previous SeenRange did — same answer, and it
no longer scans line-by-line over a large file.

* test(tools): key the large-file test on the resolved path

read_file resolves the workspace root through EvalSymlinks before recording
anything, so the tracker is keyed on the resolved path. The test asserted
against the raw t.TempDir() path, which is the same string on Windows and a
different one on macOS, where the temp dir sits under /var — a symlink to
/private/var. The SeenWhole assertions would have looked up a key that never
existed: passing here, failing on macOS CI.

Also switches the line generator to fmt.Fprintf (staticcheck QF1012).

Both from CodeRabbit on #842.

* test(tools): actually switch the line generator to fmt.Fprintf

The previous commit's message claimed this was done. It was not: the edit
silently did not apply and I reported it fixed without re-reading the file,
so builder.WriteString(fmt.Sprintf(...)) survived at the head — caught by
@anandh8x, not by me.

Verified this time by running the linter rather than by reading the diff:
golangci-lint --enable-only unused,ineffassign,staticcheck ./internal/tools/
reports 0 issues.

* fix: keep exact-read workflows recoverable

* test: cover permission normalization wiring

* fix: commit file observations after output budgeting

* fix: defer file observations across retries

* test: normalize patch line endings

15b7a5475c fix(acp): interrupt idle reads on cancellation (#782)
* fix(acp): interrupt idle reads on cancellation

* fix(acp): make idle-read interruption per-Read, not per-Serve-call

Addresses the P2 on #782.

The previous design raced a single, whole-connection Once (endRead) between the
read loop's own "I have a terminal result" claim and a watcher goroutine's
"ctx is done, treat this as interrupted" claim. This has a real, deterministic
failure mode that has nothing to do with goroutine-scheduling luck: bufio.Reader
can obtain data AND a terminal error from ONE underlying Read call (io.Reader
explicitly permits returning (n>0, err) together). If a line delimiter is found
within that data, ReadBytes returns the line with a nil error for that call, but
bufio caches the error internally and returns it — without ever touching the
underlying reader again — on the very next ReadBytes call. If cancellation
happens in the gap between that first, successful read and the next one (e.g.
while a synchronously-dispatched handler is still writing its response), the
watcher's ctx.Done() case fires and claims the Once BEFORE the read loop ever
gets back to a ReadBytes call — so when the cached error then surfaces (with
zero contact with the underlying reader, let alone anything closing it), it is
misattributed as a cancellation-driven interruption and silently swallowed as a
clean shutdown, hiding a genuine broken transport.

The fix moves interruption-detection down to the Read call itself instead of
bracketing the whole Serve loop. interruptibleReader wraps the connection's
reader: each Read runs the underlying call on its own goroutine and races it
against ctx.Done(). If the underlying call finishes first, its result is
returned untouched — cancellation a moment later has no bearing on a call that
already had its answer. If ctx.Done() fires first, the reader is closed (when
closable) to nudge a genuinely blocked read, a generation counter is bumped, and
the call still waits for and returns the underlying call's own result rather
than a synthesized one.

Serve then brackets each ReadBytes call (which may invoke the wrapped Read zero
or more times — zero when bufio answers from its own buffer, including a
previously-cached error) with a snapshot of that counter before and after. A
read whose bracket shows no change was never raced against cancellation — either
answered from the buffer or genuinely completed before ctx.Done() could matter —
so its outcome is reported truthfully regardless of the ctx state by the time it
surfaces. Only a bracket that changed proves this specific call actually took
the cancellation branch.

Verified the fix has teeth: reverted to the original implementation and
confirmed the new regression test (which forces the exact bufio-caching
sequence deterministically, with a panic guard proving the underlying reader is
never called a second time) fails 100% of the time against it, then restored
the fix and confirmed it passes.

Also applied the two open review threads on the existing tests: readStarted and
writeStarted are now buffered channels with non-blocking sends rather than
close(), so a future change causing an extra read or write can't panic on a
double-close.

Validated with go build/vet/test on Windows, plus go vet/build and
`go test -race ./internal/acp/... -count=50` (and count=100 focused on the
cancellation/error tests) under WSL/Linux — this session's Windows host has no
C toolchain for -race directly.

* fix(acp): preserve decided read results and require explicit reader ownership

Addresses jatmn's two #782 review findings:

- interruptibleReader.Read's select between resultCh and ctx.Done()
  chooses pseudo-randomly when both are ready, so a real terminal read
  error decided just before cancellation could be misattributed to
  shutdown and silently swallowed. Re-check resultCh non-blockingly
  before claiming a call for cancellation.

- NewConn inferred reader ownership from an io.Closer assertion and
  closed any reader that happened to implement it, including one a
  caller merely borrowed. Split into NewConn (never closes r) and
  NewOwnedConn (explicit ownership, closes r on cancellation), and
  switch the sole production call site (process stdin) to the latter.

Also applies CodeRabbit's atomic.Int64 and leading-ctx-parameter nits.

bdbda89f3e fix(swarm): close lifecycle admission on shutdown (#776)
* fix(swarm): close lifecycle admission on shutdown

* fix(swarm): admit lifecycle work without holding the lock across Launch

Addresses the P1 on #776 plus the two documentation P3s.

[P1] beginLifecycleAdmission returned with lifecycleMu.RLock() held for the
caller's entire duration — including the call into the injected
MemberLauncher.Launch. Close needs the write lock before it can call s.cancel(),
so a launcher that blocks in Launch waiting on its context (the ordinary shape of
a launcher that waits for a slot, a daemon connection, or a sandbox handshake)
deadlocked every Close caller: the launch held the read lock while Close waited
for the write lock to reach the very cancellation the launch needed to unblock.

beginLifecycleAdmission is now a counted ticket: it holds lifecycleMu only across
the closed check and a lifecycleWork.Add(1), then returns a release func
(lifecycleWork.Done) the caller defers. Close flips closed and releases the lock
BEFORE calling cancel, then waits out lifecycleWork (admitted-but-unfinished
work) followed by watchers (goroutines admitted work may still be starting) — so
it remains a true completion barrier without holding any lock across external
launcher code. Every call site (Spawn, Handoff, AdoptOrphans, the retry path in
watch, and afterExit) moved to the ticket pattern.

[P3] beginLifecycleAdmission's contract and the Scheduler/Close handoff are now
both documented at the point that matters: the func-returning signature makes
the release contract explicit in the type itself, and Scheduler's comment spells
out why the read/write lock ordering guarantees exactly one of Scheduler or
Close closes whatever scheduler ends up installed.

Tests: TestCloseCancelsLauncherBlockedInLaunch reproduces the exact deadlock
(spawn parked in Launch, Close in a second goroutine, both must complete once
cancellation reaches the launcher) — verified it hangs under the old held-lock
pattern by temporarily restoring it. TestCloseWaitsForAdmittedSpawn is the
converse: Close must not return while an admitted spawn is still running.

Validated with `go test -race ./internal/swarm/... -count=1` under WSL/Linux
(this session's Windows host has no C toolchain for -race directly), plus
`go vet ./...` under WSL and go build/vet/test on Windows.

* fix(swarm): fail late queue admissions and dequeues after shutdown

Addresses jatmn's two #776 review findings:

- Close swept (clearQueue) every team's queue before waiting for
  admitted-but-in-flight lifecycle operations to finish. A Spawn,
  Handoff, or AdoptOrphans call that got its ticket right before
  closed flipped could still append to a team's queue after the
  sweep ran, stranding that spec forever (never launched, since
  shutdown began; never failed, since the sweep won't run again).
  Reorder Close to wait for lifecycleWork before sweeping queues, so
  every queue append from already-admitted work is visible to the
  sweep.

- afterExitAdmitted dequeued a queued spec (t.onExit) and launched it
  unconditionally once its own ticket was granted, even though Close
  can flip closed in the gap between that dequeue (which makes the
  spec invisible to the clearQueue sweep) and the launch. Re-check
  closed after dequeuing so a spec pulled off the queue after
  shutdown began fails with ErrSwarmClosed instead of starting a new
  worker.

Both regression tests are verified to fail against the pre-fix code
(confirmed by temporarily reverting each fix and rerunning).

* fix(swarm): reject late admitted launches during shutdown

Re-check the closed state at the final launcher boundary so lifecycle work admitted before Close cannot start or retry a member after shutdown has already won the race.

Add deterministic late-dispatch and scheduler-handoff coverage, stress concurrent Spawn and Close under the race detector, and keep the late-team snapshot regression isolated from launcher behavior.

Amp-Thread-ID: https://ampcode.com/threads/T-019fa7a0-1223-701d-9529-48ba5d7cf8c8

Co-authored-by: Pierre Bruno <[email protected]>

* fix(swarm): gate retry relaunch on the post-close commit

The post-Launch shutdown gate added for spawns and queue drains was missing
from the bounded-retry path, which called the launcher and swapped in the new
handle unguarded. Since FuncLauncher returns a live handle immediately without
consulting its context, a Close landing between the pre-check and Launch's
return left the watcher supervising a member relaunched after shutdown began —
and recording that member's outcome on the task.

Extract the commit gate as commitLaunch and route the relaunch through it via
relaunchAdmitted, so an initial launch and a retry pass the same three gates:
admission, the pre-Launch re-check, and the post-Launch commit. When shutdown
wins, the handle is reaped and the watcher records the terminal failure instead
of adopting it.

Vasanth T 8acd42a3bd fix(providers): retry provably pre-send transport failures (#447) (#750)
* fix(providers): retry provably pre-send transport failures (#447)

A flaky link that failed the streaming completion POST at connect time
stopped the turn and forced a manual continue, because the shared retry
layer never retries transport errors: a completion POST is
non-idempotent, so a replay could duplicate billable work.

That rationale does not apply to a PROVABLY pre-send failure, where no
request bytes ever left this host: a replay cannot duplicate anything,
exactly like a 429/503 where the server told us it did not accept the
request. SendWithRetry now retries, with the existing backoff, only that
narrow class: DNS resolution failure, a refused or unreachable dial, and
a TLS handshake timeout. Every ambiguous or post-send failure stays
unretried and is checked first so a mixed message can never be misread:
connection reset, broken pipe, EOF, a bare i/o timeout, context
deadline. All three providers route their completion POST through this
layer, so one change covers them uniformly.

This deliberately narrows the issue's ask (which listed connection
reset) to the provably-safe subset, and keeps the reset-stays-unretried
test green. Tests cover the retry-on-pre-send, no-retry-on-ambiguous,
and predicate-classification paths.

NOTE FOR REVIEW: this refines a deliberately conservative, documented
no-retry stance. Opening it for the owner's sign-off on the stance, not
as a settled call.

* fix(providers): classify pre-send dials by errno so Windows retries too

CodeRabbit flagged that the pre-send predicate matched only POSIX dial
wording, so a refused or unreachable dial on Windows (whose text differs
entirely: 'No connection could be made because the target machine
actively refused it') would not be retried.

Match the syscall errno via errors.Is instead: Go maps ECONNREFUSED /
ENETUNREACH / EHOSTUNREACH / ECONNRESET to the host's real values,
including the WSA codes on Windows, so classification is identical on
every platform. Errno matching is also authoritative where the string
markers were only heuristic, closing the theoretical substring gap. The
string markers stay as a fallback for errors already flattened to text.
ECONNRESET is added to the post-send exclusions by identity so a Windows
reset is excluded too.

Tests build the production error shape (net.OpError -> os.SyscallError ->
errno) so the Windows path is exercised portably on every platform, plus
an end-to-end SendWithRetry case for an errno-wrapped refused dial. Cross
-compiled and vetted for linux and darwin.

* fix(providers): scope pre-send retry to the dial phase and fail fast on permanent errors

Addresses gnanam's two [Major] review findings on this PR.

[Major] Pre-send errno classification was not scoped to the dial, so a post-send
read/write carrying ECONNREFUSED/ENETUNREACH/EHOSTUNREACH (a route dropping
mid-generation) was misclassified "provably pre-send" and could replay a
non-idempotent completion POST up to 6 times. errors.Is matches an errno
anywhere in the chain regardless of which operation raised it, so
isPreSendTransportError now requires an Op=="dial" *net.OpError before admitting
those errnos or their POSIX wording. That makes "no request bytes were sent"
structural: a post-send failure can no longer replay a POST. The dial errno
match still covers Windows (Go maps the WSA* codes), so the platform coverage
this PR added is preserved.

[Major] Permanent failures hung the agent ~60s on the 429-tuned schedule.
NXDOMAIN (net.DNSError with IsNotFound) is now treated as permanent and not
retried, and the pre-send path gets its own short bound and sub-second schedule
(preSendMaxAttempts=3, 500ms/1s) instead of reusing the 2/4/8/16/30s rate-limit
backoff, so a mistyped host or a dead local daemon fails in about 1.5s.

[Minor] Fixed the stale SendWithRetry doc that still claimed transport errors are
never replayed.

Tests: post-send read/write errnos and NXDOMAIN now assert exactly 1 call (no
replay); dial errnos plus the string fallback assert the pre-send cap; added the
pre-send backoff schedule. Race detector and all provider packages green.

* fix(providers): match Windows WSA dial errnos so refused dials retry on Windows too

CodeRabbit caught a real Windows bug, which I verified with a real dial on
Windows: errors.Is(err, syscall.ECONNREFUSED) returns FALSE for a refused dial
there, because a real Windows dial carries the raw WSAECONNREFUSED (10061) while
Go's syscall.ECONNREFUSED is a distinct value the net package never produces. The
POSIX string fallback ("connection refused") does not match the Windows wording
("No connection could be made because the target machine actively refused it")
either. So the pre-send dial classification silently never fired on Windows, the
exact platform this PR set out to fix.

Move the dial errnos into a platform-specific list (dialPreSendErrnos): POSIX
everywhere, plus the WSA* codes on Windows. The existing wrapDialErrno fixtures
wrap the Go syscall constants, which is why they passed on both platforms and
missed this. Adds TestIsPreSendTransportErrorRealRefusedDial, which does a REAL
refused dial and asserts pre-send classification, so the platform's true error
shape is exercised on every OS.

* fix(providers): exclude Plan 9 from the POSIX dial-errno build tag

* fix(providers): keep the pre-send errno classification off Plan 9

retry.go referenced syscall.ECONNRESET and dialPreSendErrnos directly, but the
errno definitions live in build-tagged files that exclude Plan 9 (which has no
BSD-style errno constants), so the package stopped compiling for GOOS=plan9 on
this branch even though it builds on the merge base.

Move the two syscall touch-points behind per-platform helpers: retry.go now
calls isConnResetErrno and ranges dialPreSendErrnos, both provided by
retry_dialerrno.go, retry_dialerrno_windows.go, and a new
retry_dialerrno_plan9.go. The Plan 9 variant supplies an empty errno list and a
false isConnResetErrno, so retry.go falls back to its existing string-marker
heuristics there. Behavior on linux/darwin/windows is unchanged (isConnResetErrno
matches the same syscall.ECONNRESET as before). retry_test.go is tagged !plan9
because it constructs real syscall.Errno dial shapes.

Verified: GOOS=plan9 build and vet now pass; windows and linux build, vet, gofmt,
and the full providerio test suite stay green.

* fix(providers): stop pre-send retry from replaying a redirected POST

Addresses jatmn's review on #750.

[P1] client.Do could follow a 307/308 after already transmitting the original
POST, and a dial failure to the redirect target then satisfied
isPreSendTransportError and replayed the request, re-billing a completion the
first host already received. SendWithRetry now disables redirect following
(CheckRedirect returns http.ErrUseLastResponse on a cloned client), so any
dial/DNS/TLS error from Do can only come from the single initial request and
the pre-send classification is sound. A 3xx surfaces as the response for the
caller's existing non-2xx handling. Regression test asserts the POST is sent
once and the 307 is not followed.

[P2] The pre-send retry used the loop-wide attempt counter shared with 429/503
retries, so a couple of status retries exhausted the pre-send budget and the
first dial/DNS/TLS blip after them got no retry. Track pre-send failures and
their backoff ordinal in a separate counter. Regression test covers a
status-then-transport-failure sequence.

[P3] Correct the Plan 9 and wrapDialErrno comments: the Plan 9 string-marker
fallback keeps the pre-send inclusions and the separate reset exclusion, and
the errno fixtures do not reproduce a real Windows dial (that carries distinct
WSA errnos), which the real-dial test covers.

* fix(providers): decouple the status retry budget from pre-send retries

Addresses jatmn's follow-up on #750.

The previous change gave pre-send failures their own counter, but every retry
still advanced the loop-wide attempt counter that the 429/503 branch used. So
the coupling survived in the opposite direction: two safely replayed refused
dials shortened the later status retry window and started its backoff at a
later rung.

Give the status path its own statusAttempts counter and backoff ordinal. With
both budgets tracked separately the shared loop counter has no remaining
reader, so the loop no longer carries one. Behaviour is unchanged when only one
kind of failure occurs: the first retryable status still waits on rung 1 and
still gets maxAttempts requests.

Adds TestSendWithRetryStatusBudgetSurvivesPreSendRetries, the inverse of the
existing mixed-sequence test: two refused dials followed by rate limiting must
still leave the status path its full window.

* fix(providers): keep following redirects, but never replay a redirected POST

Addresses jatmn's follow-up on #750.

Blocking redirects outright was too blunt. SendWithRetry is the shared
completion path, so replacing every caller's CheckRedirect with
ErrUseLastResponse turned a legitimate 307/308 from a redirecting
OpenAI-compatible gateway into a terminal non-2xx that providers report as an
upstream error, and it discarded an injected client's redirect policy.

Observe the redirect instead of preventing it: a per-attempt flag is set from
CheckRedirect, which then delegates to the caller's policy when one is set and
otherwise mirrors net/http's default ten-hop cap. The pre-send retry is gated on
that flag, so an attempt that entered a redirect is never replayed while
redirecting endpoints keep working. The safety property is unchanged, since a
dial failure on a redirect hop follows a POST the origin already received.

Adds three regressions: a redirect is followed through to the final response, a
dial failure after a redirect is not replayed, and a caller-supplied
CheckRedirect still runs and still decides.

* test(providerio): pin the redirect asymmetry for retryable statuses

A reviewer read the redirect guard as incomplete, because it stops a redirected
POST being replayed after a transport error but not after a 429/503/529. The
asymmetry is intentional, and nothing recorded that, so the next reader would
reasonably reach the same conclusion.

The two cases differ in what is known about the request. A transport failure
after a redirect leaves it unknown whether the redirect target received and
began processing the POST, so replaying could duplicate billable work. A
retryable status means every hop answered: the 307/308 is the origin declining
and delegating, and the 429 is the target declining as well, so nothing accepted
the request and a replay duplicates nothing.

The exposure is also the same as a retryable status with no redirect involved,
which this package has always retried, so guarding here would not close a gap.
It would make a rate-limited completion behind a redirecting gateway fail
outright rather than back off, which is the regression class already raised
against disabling redirects wholesale.

Adds the case as a test asserting the intended behaviour, plus a comment at the
branch explaining why it is not guarded.

* fix(providers): retry connect timeouts and proxy CONNECT failures

Three classification gaps against #447, all raised in review.

A connect-phase timeout was never retried. It is provably pre-send for the same
structural reason a refused dial is, since the connection was never established
and no request bytes left this host, but it arrives carrying "i/o timeout" and
the blanket wording exclusion rejected it before the connect gate could admit
it. Intermittent connect timeouts are exactly the transient failure the issue
is about, so the most common case was the one not covered. It is now admitted
ahead of the wording exclusions, gated on the connect phase so a post-send read
timeout, which is also Timeout(), still cannot replay a POST.

A failed CONNECT through an HTTP proxy was never retried either. net tags it Op
"proxyconnect" rather than "dial", so it missed the gate entirely. Same
guarantee applies: the tunnel to the model host was never built. The gate now
accepts both, which matters most in the environment where transient connect
failures are most common.

ETIMEDOUT and WSAETIMEDOUT join the errno lists so a connect timeout still
classifies if it reaches us with the errno but without the timeout flag.

The pre-send budget also now resets after a hop that reaches the server. It is
meant to bound consecutive connect failures, not the lifetime of the call, and
without the reset an early run of blips permanently spent it, so a later blip
surfaced as a transport error while the status budget still had room. That is
the coupling the two counters were split apart to remove, in the one ordering
the earlier tests missed. Total work stays bounded, since every reset costs a
status attempt and those are capped.

Also corrects the SendWithAuthRetry comment, which still claimed the inner path
retried only 429/503/529.

Tests cover dial and proxyconnect timeouts as retryable and read/write timeouts
as not, a refused proxy CONNECT, and the interleaved pre-send/status/pre-send
sequence. Each fix fails its test when reverted.

Vasanth T 1c38e8cba5 fix(config): make the provider-command timeout an upper bound (#811) (#813)
providerCommandTimeout bounded only the wait, so the call could take arbitrarily
longer than the 5s its error text promised. Two phases sat outside it.

Starting the process ran before the clock began. On Windows that is
CREATE_SUSPENDED, job-object creation and assignment, and a system-wide thread
snapshot, none of it fast on a cold or contended machine. The deadline is now
armed first and the start races it, so process creation is inside the budget.

Draining after termination was unbounded too: the timer path called Terminate
and then received on the wait with no limit. Terminate normally makes that
immediate, which is exactly why it survived unnoticed, but a tree that resists
termination held the call open long past the deadline that had just expired.
That receive is now bounded, and a call that gives up leaves cmd.Wait running,
so the output buffers are synchronised: the I/O pump keeps writing into buffers
the caller already holds, which a plain bytes.Buffer cannot survive.

The timeout error also carried nothing actionable. It was a bare string with the
underlying error and the command's stderr both dropped, so a user whose provider
command was slow got no clue which phase ran out or what the command had said.
It now names the phase, wraps the cause, and includes the redacted output the
failure path already had.

Both bounds are asserted on extracted helpers rather than end to end, because
end to end they are untestable: a terminated command stops writing and its wait
returns at once, so an unbounded drain and an unsynchronised buffer both pass a
whole-call test. The first version of these tests did exactly that and proved
nothing. Removing either bound now fails, as does arming the deadline after the
start, which reports the wrong phase.

Vasanth T 3e7692d8f0 fix(sandbox): scrub the daemon token file pointer (#677) (#818)
scrubSensitiveEnv removed ZERO_DAEMON_REMOTE_TOKEN but not its file
counterpart. TokenFromEnv accepts either form, so a sandboxed command
still inherited the path to the bridge token, and the default posture is
read-all, so it could then read the token itself.

Scrubbing the pointer is the whole fix rather than half of one: the path
comes from this variable alone and TokenFromEnv has no default location
to fall back on, so a command that never sees the variable has nothing to
guess at. This mirrors GOOGLE_APPLICATION_CREDENTIALS, which is already
scrubbed for the same reason.

Extends the existing scrub table, which compares the surviving
environment exactly, so the case fails if the entry is dropped. Verified:
without the fix the assertion reports ZERO_DAEMON_REMOTE_TOKEN_FILE
surviving into the scrubbed environment.

Vasanth T 33c94ec7a3 fix(sandbox): deny reads of git's credential stores (#815) (#816)
* fix(sandbox): deny reads of git's credential stores (#815)

git's credential-store backend keeps host passwords and personal access tokens
in cleartext, at ~/.git-credentials or ~/.config/git/credentials depending on
whether the user is on the XDG layout. Neither was on the deny list, so any
command the agent runs could read them.

Scoped to those two files deliberately. #815 also covers SSH private keys and
the GPG keyring, and those are a harder trade: denying ~/.ssh stops a sandboxed
git push over SSH from working, and excluding that directory is not even
sufficient, since an IdentityFile directive can point key material anywhere.
These two cost nothing by comparison, because git reads them to authenticate
rather than to know who the user is, so a sandboxed git keeps working and
simply cannot act as the user.

The XDG one denies the file rather than the directory around it, which is the
opposite of the choice made for ~/.config/zero and is deliberate: ~/.config/git
also holds the global git config, which userGitConfigReadPaths grants on
purpose so a sandboxed git can read user.name and aliases instead of failing
outright. Denying the directory would take that away.

Tests assert both stores are denied, that the git config beside the XDG one
stays readable, and that an explicit read grant still re-includes them like
every other entry. Dropping either entry fails the first; widening the XDG
entry to the directory fails the config assertion.

* test(sandbox): assert the credential deny exists before the grant lifts it

The allow-read case only checked that the credential store was absent from
the deny list once an explicit grant covered it. A deny rule that was never
added satisfies that just as well, so the test passed with the production
change reverted and proved nothing about the interaction it was named for.

Check both runs: denied with no grant, absent with one. The first leg is
what establishes there is something for the grant to override.

Vasanth T c9f9dc02ef test(tools): stop internal/tools failing on stock Windows (#814)
* test(tools): stop internal/tools failing on stock Windows

This package fails on every run on a Windows box without PowerShell 7, which
is what a stock install is: PowerShell 7 is a separate download. CI never sees
any of it, because the runners have 7. Three distinct causes, all surfaced by
the move to PowerShell in #804.

The stop-intent test waited a fixed second for a session to die and asserted on
whatever was true by then. Under cmd.exe that was enough; under PowerShell the
tree is slower to stand up and tear down, and the FIRST stop in a fresh process
pays the interpreter's cold start, so it routinely returned with termination
under way but unfinished. The assertion read that as a failed stop. It now
re-sends the stop until the session reports it has exited. Repeating is safe,
since Terminate is a no-op against an already-dead tree, and it keeps the
interrupt flag that a poll with empty chars would drop.

Separately, and pre-existing, every test that starts a session hit a teardown
race: a terminated process does not release its handles the instant the session
reports exited, and Windows refuses to remove a directory with an open handle
where POSIX does not. t.TempDir removes once and fails the test on the sharing
violation, so ordinary teardown timing was reported as a broken test. Those
roots now clean up with a bounded retry, and give up quietly rather than
failing: the process is already terminated, so the worst case is a stale
directory under the OS temp root.

Last, the MSYS guard test asserted a windows_shell_syntax block using a command
containing `&&`. On PowerShell 5.1 the windows_powershell_version preflight
added by #804 fires first and shadows it. The `&&` was incidental to what that
case is about, so it is gone. This one is worth noting as a shape rather than a
typo: a new preflight silently changed which block an older assertion got, and
only on the shell CI does not run.

Verified by running the package repeatedly rather than once: previously failing
on every run, now passing 3 of 3, and the stop-intent test passing 8 of 8 alone
and 6 of 6 under CPU contention. Disabling the terminate path still fails it,
so the assertion continues to bind.

* test(tools): assert the stop intent killed the session

The retry loop added to survive a slow PowerShell teardown also made the
test unfalsifiable. The helper sleeps 5s, well inside the 30s deadline, so
a terminate that did nothing at all would let the sleep end on its own and
every existing assertion would still hold: the session reports exited, it
reports an exit code, and the interrupted flag echoes the request rather
than the outcome. Neutering KillProcessTree confirmed it, the test passed.

Assert instead that the helper's completion line never appears, which
distinguishes a killed session from a finished one without depending on
how long the loop took. Output is accumulated across every poll rather
than read off the last result, because each continuation returns only what
the session produced since the previous collection.

Vasanth T ec3b822505 fix(tui): paste clipboard images with Ctrl+V (#534) (#807)
* fix(tui): paste clipboard images with Ctrl+V

Ctrl+V did nothing when the clipboard held a screenshot, while right-click
paste attached it. The image plumbing was already there: routePaste probes the
OS clipboard for an image whenever a paste arrives with empty text.

The gap is that a clipboard holding only an image produces no bracketed paste
at all, since the terminal has no text to send, so routePaste never runs and its
probe never fires. Right-click reached the probe only because that path always
delivers a clipboardReadMsg, empty or not. Bubble's own Ctrl+V binding stays
disabled, so nothing else was listening for the key.

Handle Ctrl+V by issuing the image probe directly. It reads image content only,
never text, so bracketed paste remains the single text path and a Ctrl+V with
text on the clipboard is unaffected. The probe yields no message when there is
no image, keeping it a silent no-op, and it is gated on noBlockingModal so a
permission prompt or picker still swallows the key.

readClipboardImage becomes a var so the tests stub it instead of depending on
the machine's real clipboard.

Fixes #534

* fix(tui): also probe the clipboard on Cmd+V, and test the real key route

Two things raised in review, both fair.

The handler matched keyCtrl only, which is ModCtrl. macOS reports Command as
ModSuper, as the rest of the TUI already models it, so Cmd+V never reached the
image probe even though the change claimed to cover it. It now matches both, via
a keySuper helper alongside the existing modifier helpers.

Worth being precise about the limit: this only helps where the terminal delivers
the key to the application. A terminal that handles Cmd+V itself pastes the
clipboard TEXT and sends no key event at all, so an image-only clipboard still
produces nothing for this to react to. That is a separate problem from the one
being fixed here.

The tests also did not exercise the route they were named for. One asserted that
Update returned some non-nil command and then ran a freshly built probe; the
other never called Update at all. Both now stub the reader BEFORE Update and run
the command Update actually returned.

That matters more than it sounds. Making the branch return a different non-nil
command leaves the old assertion passing and fails the new one, which is exactly
the hole: the old test proved a command was issued, not that it was the image
probe. Removing the route entirely, or reverting to ModCtrl only, also fails now.

* fix(imageinput): report an unreadable clipboard image instead of silence

On macOS the clipboard reader shells to pngpaste or a PyObjC one-liner, and
neither ships with the OS: pngpaste is Homebrew-only and Apple dropped the
bundled PyObjC. A stock Mac therefore fails every time, and the failure was
returned as (nil, nil), which the caller reads as "no image on the clipboard"
and treats as a silent no-op. Pressing Ctrl+V produced nothing at all: no
image, no error, no hint that anything was missing.

The darwin path already knows the difference. It probes with `clipboard info`
first and only reaches the extraction step once the clipboard is confirmed to
hold an image, so a failure there is not absence, it is "there is an image and
nothing here can read it". That now returns ErrClipboardImageUnreadable, which
the existing error path turns into a transcript notice naming what to install.

The defect predates this branch, but this branch is what makes the path
reachable from Ctrl+V, so shipping without it would close #534 with a feature
that is inert on one of the three platforms. Raised by gnanam, who measured it
on a real Mac rather than inferring it.

Deliberately narrow. The Linux arm cannot tell "no tool" from "no image"
without probing separately, and Windows uses PowerShell, which is always
present, so neither is touched.

The test drives the whole path: stubbed reader returns the error, Ctrl+V
issues the probe, and the assertion is that the failure reaches the transcript
as an error row rather than stopping earlier. Swallowing the error again makes
it fail.

* test(imageinput): cover the darwin unreadable-clipboard decision itself

The test added with the fix asserted around the change rather than on it. It
substituted ReadClipboardImage with a stub returning the error, which proves
the TUI surfaces an error handed to it, but never reaches
readClipboardImageDarwin, where the decision lives. Reverting both production
return sites to nil,nil left every package green, which is the definition of a
test that is not testing the change. Caught by gnanam.

readClipboardImageDarwin shells out twice and had no seam, so the two steps are
now package-level vars, the same shape as the readClipboardImage var this
change already relied on. That makes the case that matters reachable: the info
probe succeeds and reports an image, and the extractor then fails. It cannot be
arranged from outside the function, because from there both steps are one
opaque call.

Five cases, and the negative ones carry as much weight as the positive. An
image with no working extractor, and an extractor that exits 0 with no bytes,
must both be actionable. A clipboard offering no image, and a failing info
probe, must both stay silent, because turning those into a notice would make
every stray Ctrl+V nag the user. The extractor must not run at all in either
silent case.

Repeating gnanam's experiment now fails: reverting both return sites to nil,nil
fails the two actionable cases and leaves the silent ones passing, which is
exactly the discrimination the fix is supposed to add.

Configure UTF-8 output, preserve restricted-sandbox MSYS safeguards, and add Windows coverage for pipelines, workspace writes, and interactive stdin sessions.

* test(windows): align shell coverage with PowerShell

Make Windows command fixtures and guidance assertions follow the selected host shell, preserve cmd fallback coverage, and use a genuine MSYS executable when PowerShell aliases are available.

Remove the unsupported non-TTY PowerShell stdin assertion; Windows interactive stdin requires a separate PTY transport.

Vasanth T d82b94defe test(cli): order the prewarm probe against the turn (#809)
* test(cli): order the prewarm probe against the turn

TestRunExecOptimizedSessionUnderGate intermittently sees zero prewarm HEAD
probes on the Windows runner. It polled for up to 5s after the run returned,
reasoning that the deadline exceeded the 3s prewarm timeout so a slow probe
could not flake it. That reasoning does not hold. The probe is issued on the
run's context and runExec cancels that context as it returns, because the stop
function signalContext hands back is a CancelFunc. Once the run is over the
probe is cancelled rather than slow, so polling cannot observe one that has not
already landed, at any deadline.

Against a mock server the turn finishes in microseconds, which leaves the probe
racing teardown. The turn now blocks until the probe arrives, giving it a
window while the run is still alive. The wait is bounded, so a probe that never
fires still fails the assertion with a useful message.

This widens the window rather than closing it: prewarmTimeout is armed inside
the probe goroutine, so holding the turn cannot extend it. The comment says so,
and names prewarmTimeout as the thing to look at if this ever recurs.

* test(cli): fail when the prewarm hold gives up

The bounded wait let the turn proceed after its guard expired, so a probe that
arrived late still left the count at 1 and the test passed. That proves the
probe was eventually received, not that it preceded the turn, which is the only
thing this test claims. Raised by CodeRabbit.

The expiry is now recorded and checked before the count, since the count cannot
tell the two apart.

Verified by suppressing the probe, which makes the guard expire: the assertion
fires with its own message rather than the count assertion, and the run takes
the full guard duration.

* fix(sandbox): do not lock the grants file when there is no notice to consume

Addresses jatmn's #755 finding.

ConsumeMigrationNotice took the interprocess lock unconditionally, and
lockStateFile MkdirAlls the grants directory and creates
<grants>.lockfile. Every startup and every 'zero exec' calls this, so it
turned reading the grant state into requiring a WRITABLE grants
directory: a user with no grants file whose ZERO_SANDBOX_GRANTS_PATH (or
its parent config directory) sits on a read-only mount failed outright
with 'failed to migrate sandbox grants', where the pre-lock code read an
empty state and wrote nothing.

Peek at the state without the lock first and return early when no
migration write is required. Only when one is — a schema/policy
migration, or clearing NoticePending — take the lock and re-read under
it, since the unlocked peek is a snapshot another process may have
already consumed or migrated, and is meaningless by contract when
needsMigration is set.

Both regression tests are verified to fail against the pre-fix code.
The read-only-directory test skips on Windows (mode bits do not deny
writes) and as root (permissions are bypassed), so a portable companion
asserts the same requirement by requiring that nothing is created at
all.

PierrunoYTandClaude Sonnet 5 0125e70d0f Fix pinned Go quality tools on Go 1.26 (#689)
* fix pinned Go quality toolchain

* fix(make): use a POSIX GOTOOLCHAIN prefix for pinned tool targets

The Windows_NT branch used cmd.exe syntax (set "..." &&), but GNU Make
runs recipes through sh even on Windows (MSYS/Git Bash), where that
form fails and breaks make lint-static/deadcode/vulncheck. A plain
GOTOOLCHAIN=... prefix works everywhere, so the OS check is gone.

Also switch GO_VERSION/GO_TOOLCHAIN to recursive expansion so
'go list -m' only runs when a tool target actually needs it, instead
of at parse time for every target. Addresses PR review from CodeRabbit
and Copilot.

Co-Authored-By: Claude Fable 5 <[email protected]>

* fix(build): make pinned-tool targets shell-neutral, fix README drift

Address code review on PR #689:

- lint-static/deadcode/vulncheck previously set GOTOOLCHAIN via a
  POSIX `VAR=value cmd` recipe prefix. GNU Make on Windows runs
  recipes through whatever SHELL is configured, and under a native
  cmd.exe setup that syntax is invalid — cmd.exe treats the whole
  "GOTOOLCHAIN=go1.26.5" token as the program to run and fails before
  go ever executes (reproduced locally: cmd.exe errors with
  "'MYVAR' is not recognized..." for the equivalent pattern). Switched
  to a target-specific `export`, which sets the variable in the child
  process environment via Make itself, before  is invoked —
  works under sh, cmd.exe, and PowerShell alike (verified against all
  three targets with SHELL := cmd.exe).

- README.md's Code Quality and Security Checks section still told
  contributors to run the raw `go run ...@version` commands this PR
  identifies as selecting the wrong (older) toolchain and failing to
  load this Go 1.26.5 module — only CI and AGENTS.md had been updated
  to the new make targets. Points steps 3-4 at `make lint-static` /
  `make vulncheck` instead, matching AGENTS.md.

Verified end-to-end: `make vulncheck`, `make deadcode`, and `make
lint-static` all run successfully and reach their tools (deadcode's
advisory report and lint-static's 35 pre-existing findings match the
PR's documented baseline).

Vasanth T f5fa4ffc64 fix(config): stop billing provider-command fixtures to the 5s timeout (#810)
Both background-child tests fail intermittently on the Windows runner, and
have since #690. #800 and #802 each relaxed an assertion, which is why neither
held: the deadline itself was the problem.

The tests drove LoadProviderCommand, so the fixture's own startup was billed to
the production 5s budget. On a loaded runner the outer timer won the select in
runProviderCommand, and both symptoms follow from that. The nonzero-exit test
saw a timeout instead of the exit status it asserts, because the timer
preempted the shell's exit. The other test lost its PID file, because the
timer's Terminate killed the background child before it could record a PID,
putting the file permanently out of reach however long the assertion polled.

Neither test is a claim about the 5s budget. They assert which error each
cmd.Wait path yields and that the leftover descendant is killed, so they now
call runProviderCommand directly with a budget of their own and the production
deadline stops competing with process startup. Making the child outlive that
budget lets both drop their elapsed-versus-lifetime bounds as well, so no
wall-clock assertion is left in either test.

That is only worth doing if the two timeout paths can be told apart, and they
could not: the WaitDelay path and the outer-timer path both returned the same
bare sentinel, so asserting on it would have been satisfied by the very timeout
the tests exist to rule out. The WaitDelay path now wraps rather than replaces.
Callers asking errors.Is for the sentinel are unaffected, so no user-visible
message changes.

The Windows fixture also waited for its ready marker by launching a second
PowerShell. That cold start is pure overhead added after the PID is already
written, so the wait now runs in cmd itself and is bounded.

Verified by looping both tests under CPU contention: 7 failures in 16
iterations before, none in 32 after, with per-iteration time going from a
spread of 2.3s to 66s down to a steady 2.1s. Removing the wrap makes the
WaitDelay assertion fail, so it is load-bearing rather than decorative.

euxaristiaandClaude Sonnet 5 97ef90d27a chore: remove code unreachable on every supported platform (#706)
* chore: remove code unreachable on every supported platform

The Security and code health job's advisory deadcode step reports 152
unreachable functions on main. Running the same check under GOOS=linux,
windows, and darwin shows 13 of those are false positives whose callers
live in windows build-tagged files, so only functions unreachable on all
three platforms are touched.

Functions with no references anywhere are deleted, including the
internal/reasoning package, which nothing imports. Functions that only
tests reference move into per-package export_test.go files so tests keep
their seams while the production binary sheds the code. Test call sites
of deleted convenience wrappers are ported to the live APIs (scoped tool
constructors, tools.DeferredSource, FinishReason checks).

Kept despite the report: cron.Store.Runs (only reader of runs.jsonl,
which production writes), and agenteval.TraceEventKeys and
MissingTraceEvents (used across packages by the trace contract test).

* docs(config): correct ValidateFile's errors.As claim

Message is a flattened string (.Error() already called on the parse
error), not a wrapped error, so callers can't recover the concrete

PierrunoYTandClaude Sonnet 5 5c58256abc fix(config): kill provider-command process tree via job object on Windows (#690)
* fix(config): kill provider-command process tree via job object on Windows

taskkill /T walks the process tree by parent PID in user space and can
miss descendants, leaving the sleeping child holding the inherited
stdout/stderr pipes so cmd.Wait() blocked until natural completion
(~10s instead of the 5s timeout).

Assign the started command to a job object with
JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE and terminate the job on timeout so
the kernel kills the whole tree atomically; taskkill remains as a
fallback. Also set cmd.WaitDelay so Wait can never hang on pipes held
by an escaped orphan, and add a regression assertion that the sleeping
child is actually gone after the timeout returns.

Fixes #683

* fix(config): harden provider-command tree termination

Address code review on PR #690: terminate the process tree when
cmd.Wait() returns exec.ErrWaitDelay (a background descendant kept
inherited pipes open, previously left running); start the Windows
process suspended and assign it to the job object before resuming its
main thread, closing the window where a fast child could escape the
job; drop JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE so a successful command's
detached helpers survive Close() instead of being reaped; escape
single quotes in generated PID-file paths; and correct a misnamed
Windows exit-code constant in a comment.

* fix(config): avoid gofmt smart-quote rewrite in doc comment

gofmt's doc-comment formatter rewrites a trailing '' into a curly
closing quote, which CI's gofmt -l check flags as unformatted. Reword
to avoid the pattern instead of embedding a raw quote pair.

* fix(config): terminate leaked descendants on nonzero exit, avoid PID reuse

Terminate the process tree on any error returned from cmd.Wait, not only

exec.ErrWaitDelay. Go only returns ErrWaitDelay when the shell itself

exited successfully; a nonzero exit (e.g. sleep 600 & exit 7) yields the

bare *ExitError instead, so a detached background child that held the

inherited pipes open was never terminated on that path.

Also stop falling through to the taskkill/PID fallback once a job handle

successfully contained the tree: by the time Terminate runs on the

ErrWaitDelay path, cmd.Wait has already reaped the root process, so its

PID may have been reused by an unrelated process, and taskkill /T /PID

against a reused PID would force-kill the wrong tree.

Addresses PR #690 review feedback.

* fix(config): surface suspended-thread resume failures instead of hanging

resumeMainThread now reports whether it actually resumed at least one

thread. If Toolhelp/OpenThread/ResumeThread all fail, the launched

process would otherwise sit suspended forever, never exit on its own,

and get misreported as a plain 5s provider-command timeout instead of

the real resume failure. attachCommandProcess now terminates the

process immediately in that case.

Also documents the known, non-regressive limitation that the taskkill

fallback (used only when job creation/assignment itself fails) can

still miss a descendant that has reparented away from the tree it

walks by PID.

Addresses remaining PR #690 review feedback; PR description corrected

separately to drop the outdated JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE claim.

* fix(config): guard taskkill with retained process identity

* fix(config): retain POSIX process group identity

* test(tui): match provider wizard shortcut

* test(tui): pin credential-step env for deterministic footer assertion

The credential step's footer only shows the /→ shortcut once a key
is present, whether typed or inherited from the provider's
AuthEnvVars. The previous commit changed the assertion to
"Enter/→ continue" without accounting for that, so the test only
passed by coincidence when ANTHROPIC_API_KEY happened to be set in the
environment — failing deterministically on a clean CI runner (as
smoke reported on all three OSes). Pin the env var empty and assert
the no-key footer text so the test is correct regardless of ambient
environment.

euxaristiaandClaude Fable 5 5bb1bc11c3 fix(tui): fix rendering corruption over multipass + Windows Terminal (#709)
* fix(tui): disable bubbletea hard scroll optimization unconditionally

Vendors a patched charm.land/bubbletea/v2 (via a local go.mod replace)
with hard scroll optimization (using terminal scroll-region sequences
to shift existing lines instead of repainting) disabled unconditionally,
instead of only on GOOS=="windows".

That GOOS check only catches a Windows terminal driving the program
directly. It misses a Linux process running inside a multipass VM
whose output is ultimately displayed by Windows Terminal over a
remote shell, which corrupts rendering badly (garbled/overlapping
text, worse on resize) the same way the check exists to prevent.
There's no reliable way to detect that remote hop from inside the VM,
so scroll optimization is now off in all cases.

* fix(tui): force redraw on streamed newlines to clear stale caret

The streaming caret (appendStreamingCursor) is appended to whichever
visual line is currently last. Over a remote terminal chain
(multipass VM output displayed by Windows Terminal), the renderer's
incremental cell diff sometimes fails to clear the caret's old cell
when a newline moves it to a new line, leaving ghost carets behind.

Fire tea.ClearScreen when a streamed delta contains a newline: that's
exactly the moment the caret moves and the risk exists, so it forces
a full redraw right then instead of leaving it to the incremental
diff, without doing so on every animation tick.

* chore(tui): trim upstream repo metadata from vendored bubbletea fork

The vendored bubbletea-v2-patched module is ~99% byte-identical to
upstream charm.land/bubbletea/v2 v2.0.8; only cursed_renderer.go
differs (one line disabling hard scroll optimization). The .github
workflows, README.md, UPGRADE_GUIDE_V2.md, Taskfile.yaml and CI config
files are upstream repo metadata that serve no purpose inside this
repo, so remove them to slim the PR. The Go source and testdata golden
files are kept because Go's replace directive requires the full module
to be present and buildable.

Refs #709

* fix(tui): address review round on the rendering workaround and vendored fork

Fork correctness fixes (all flagged by review):

- key.go: KeyMediaRecord repeated the previous const expression and
  decoded record presses as previous-track; map it to uv.KeyMediaRecord.
- mouse.go: MouseButton11 likewise collapsed onto MouseButton10.
- termios_unix.go: BSDLY/BS0 are output-delay bits; read them from Oflag
  instead of Lflag so useBackspace is set correctly.
- cursed_renderer.go: count wrapped rows with (lineWidth-1)/w so an
  exact terminal-width multiple no longer inserts a blank line; compare
  colors by normalized RGBA via a nil-safe helper instead of interface
  equality (which panics on non-comparable implementations); and make
  clearScreen invalidate lastView so the queued erase flushes with the
  next frame instead of deferring until an unrelated view change — the
  reordering that could leave the ghost caret in place.
- exec_test.go: implement reset() on the spy renderer and inject it
  before Run; assert exec preserves renderer state (releaseTerminal
  with reset=false).
- logging_test.go: restore the default logger's output/prefix/flags and
  fail fast on setup errors.
- tea_test.go: tie the Quit-pumping goroutine to a channel closed when
  Run returns instead of leaking it until process exit.

TUI scoping (review P2): the forced redraw on streamed newlines is now
rate-limited to ~10/s so heavy streaming output no longer turns every
newline into a full-screen repaint, and ZERO_NO_STREAM_CLEAR=1 opts a
correctly-rendering terminal back into the fast incremental path.

Co-Authored-By: Claude Fable 5 <[email protected]>

* fix(tui): guarantee deferred stream-clear redraw and other review fixes

A throttled stream-clear could drop the redraw entirely when a
newline arrived in the last delta of a turn, leaving a ghost caret on
screen. Add a one-shot deferred flush timer plus a flush on stream
end. Fix a stale comment and a test that leaked global logger state
in the vendored bubbletea fork.

* fix(tui): use m.now for stream-clear throttle and harden tests

Drive stream-clear rate limiting through the mockable clock and a
shared streamClearThrottle constant so both the agentTextMsg and
flush paths stay in sync. Add an explicit two-newline-within-window
regression and detect ClearScreen by function pointer so tests do not
evaluate Tick side effects.

* fix(tui): relocate bubbletea fork out of third_party

Move the maintained bubbletea/v2 hard-scroll patch from
third_party/bubbletea-v2-patched to patches/bubbletea-v2 and update the
root go.mod replace. third_party/ is immutable vendored content per
AGENTS.md; a maintained fork belongs outside that tree.

* fix(ci,docs): run vendored bubbletea fork tests and document unsupported go install path

patches/bubbletea-v2 is its own Go module so `go test ./...` from the repo
root never touched its 7 test files. Add a CI step (and a make test-patches
target for local use) that runs the fork's own suite across the smoke
matrix.

The root go.mod's local `replace charm.land/bubbletea/v2 =>
./patches/bubbletea-v2` also breaks `go install
github.com/Gitlawb/zero/cmd/zero@<version>`, since a versioned install can't
resolve a replace pointing at a filesystem path. Document that path as
unsupported in README.md and docs/INSTALL.md and point at git clone + go
build instead, per jatmn's review findings on PR #709.

* ci: run vendored bubbletea fork tests with -race

CodeRabbit review on this PR. The fork exists specifically to patch a
concurrency bug (charmbracelet/bubbletea#1690), so its regression test
needs the race detector to actually catch a reintroduced race instead
of just passing on a benign-looking run.

* fix(tui): drop vendored bubbletea fork; keep stream-clear workaround

Maintainers asked not to ship an in-tree bubbletea replace: it breaks
versioned go install and is a large maintenance surface for a narrow
multipass/Windows Terminal scroll bug. Remove patches/bubbletea-v2 and
the replace directive; keep the model.go full-redraw-on-streamed-newline
workaround (ZERO_NO_STREAM_CLEAR to opt out). Restore normal install docs.

PierrunoYTandClaude Sonnet 5 d9b882eb0a fix(cron): reserve job IDs atomically (#686)
* fix(cron): reserve job IDs atomically

* fix(cron): hold the per-ID lock from reservation through persistence

Address code review on PR #686: reserveID made the timestamp directory
visible via os.Mkdir before metadata.json existed, but Remove (which
takes the per-ID lock before deleting) never coordinated with that
window. A concurrent `zero cron rm <id>` could delete the bare
reservation and report success right after Add reserved it; writeJob's
MkdirAll would then silently resurrect the directory and persist the
job anyway. A second Add could also re-reserve the same id while the
first writer was still running, putting two writers on the same
metadata path.

reserveID now acquires the same per-ID lock (used by Get/Update/
Mutate/Remove/AppendRun) for each candidate id before attempting
os.Mkdir, and returns it still held; Add releases it only after
writeReservedJob commits (or tears down) the reservation. A concurrent
Remove for that id now blocks until the reservation is resolved one
way or the other, and a concurrent Add attempting the same candidate
id serializes through the lock rather than only racing the Mkdir.

Adds two regression tests: one proving Remove waits for and removes
the committed job rather than the bare reservation, and one proving a
second reserveID call for the same candidate id blocks on the shared
lock and moves on to the next candidate.

Vasanth T 3524f795e5 fix(cli): warn when ZERO_PROVIDER overrides a providers-use selection (#767)
Closes #721.

`zero providers use <name>` wrote activeProvider to config.json and reported
"Active provider set to <name>" even when ZERO_PROVIDER was set, which applyEnv
makes win over config.json unconditionally. So the switch was reported as a
success while `providers current` still showed the env-pinned provider, a silent
no-op.

Detect the override and say so: the text path prints a note to stderr naming the
env var and the provider that stays active, and the --json path adds
effectiveProvider / overriddenByEnv fields so a machine consumer is not misled
either. The config write still lands unchanged; only the reporting is honest.

The env read is injected via a new appDeps.getenv (os.Getenv in production, left
nil by fillAppDeps like exportActiveProvider) so tests stay hermetic against an
ambient ZERO_PROVIDER. The related env-derived-profile "not found" case the issue
also mentions is already handled by the unpersisted-provider path (#707) and #716.

* fix(lsp): make the real-gopls check opt-in so a broken gopls can't fail the suite

Closes #684.

TestManagerCheckRealGopls skipped only when gopls was absent from PATH, so an
installed-but-unhealthy gopls (e.g. an unusable persistent-index cache that makes
the server exit during initialization with EOF) failed `go test ./...` for every
developer who merely had gopls on PATH.

Gate it behind ZERO_GOPLS_INTEGRATION, matching the repo's other real-server
opt-ins (internal/dictation smoke tests). The default hermetic suite keeps its
coverage on the fake server and never touches the developer's global gopls; the
real check still runs on demand with ZERO_GOPLS_INTEGRATION=1.

* test(lsp): require ZERO_GOPLS_INTEGRATION=1 exactly, so =0 keeps the check off

Vasanth T 4945684fa2 fix(sandbox): bind Windows elevated ACL setup to one no-follow handle (#765)
Closes #728.

The Windows ACL setup resolved each target's pathname independently across
os.Stat, GetNamedSecurityInfo, and SetNamedSecurityInfo (and again on rollback),
so during elevated setup a lower-privileged local user could swap a target for a
symlink/junction between operations and redirect the ACL change onto a system
object the process never validated. That is a TOCTOU across a privilege boundary.

Open each target once with a no-follow handle (FILE_FLAG_OPEN_REPARSE_POINT plus
FILE_FLAG_BACKUP_SEMANTICS, READ_CONTROL|WRITE_DAC) and drive both the read
(GetSecurityInfo) and the write (SetSecurityInfo) through that one handle, so they
hit the same kernel object. isDir is read from the same handle rather than a
separate Stat. A target that resolves to a reparse point is refused outright,
since a setup target that is a symlink/junction during elevated setup is the
swap-attack signature. Rollback re-opens no-follow rather than restoring by
pathname; the residual window is small because the target is ACL-restricted by
then, and one caller discards the rollback closure so handles are not retained for
the whole sandbox lifetime.

Tests (windows-tagged, no elevation needed): the handle-based apply plus rollback
round-trip on a user-owned temp dir, the materialize-and-remove path, reparse
rejection via a junction (needs no admin, so it runs in CI), and the not-exist
mapping. The full privilege-boundary race can't be reproduced in CI, so the guard
is verified structurally (one handle for read and write) and by junction rejection.

KRATOSandKRATOS 3967d49d64 feat(tui): permission prompt takes free-text feedback inline (#780)
* feat(tui): let the permission prompt take free-text feedback inline

"No, and tell Zero what to do differently" now opens an inline input on the
permission card instead of silently cancelling: type an instruction, Enter sends
it, Esc returns to the option list. The text is delivered as a Deny decision whose
Reason is the typed instruction, so the agent surfaces it via deniedPermissionResult
as the tool result and the model adjusts in the SAME turn — where the old cancel
returned an error and aborted the run. Empty input + Enter falls back to a plain
cancel (the prior meaning).

No agent-side change: PermissionDecision.Reason already carries free text to the
model. The UI mirrors the ask_user "type your own answer" pattern — the feedback
field reuses the shared composer input and the card renders it in the transcript
body.

Also: a focused permission prompt now suppresses the composer (and idle
hints/plan panel), keeping only the status line, exactly like the ask_user modal.
Its keys are inert anyway, so a "describe a task for zero…" box below the card was
misleading — and in feedback mode the shared input would otherwise echo in two
places.

Tests cover open / submit-as-Deny-with-text / empty-cancels / Esc-returns, the
composer suppression in both modes, and that the feedback text renders exactly
once.

* fix(tui): preserve the composer draft across permission feedback (#780 review)

anand + CodeRabbit (Major): entering feedback mode cleared the shared composer
input via SetValue(""), and neither submit nor cancel restored it — so a user
with a half-typed or queued next-turn message who chose "tell Zero what to do
differently" lost that draft.

Snapshot the composer value into pendingPermissionPrompt.savedDraft when feedback
mode opens, and restore it on BOTH exits (submit and Esc-cancel). Only the
feedback text is consumed, delivered via the decision Reason. Adds regression
tests for both paths; mutation-verified against the SetValue("") regression.

* fix(tui): guard permission-feedback backspace and clicks (#780 review)

Vasanthdev2004 review, all on the permission path:

1. Real bug: Backspace on an empty feedback field dropped a staged attachment.
   The keyBackspace case runs before the typing branch and, on an empty composer
   (feedback mode clears it), fell to removeLastAttachment — silently dropping a
   staged image/doc that savedDraft does not restore. Route Backspace to the
   shared input while typing so it is a plain edit of the feedback text.

2. Defence-in-depth: the mouse click resolver in handleTranscriptSelectionMouse
   resolved a clicked permission option (Allow included) with no typing check. It
   is safe today only because renderFocusedPermissionPrompt returns nil clickable
   offsets in feedback mode — a single early-return in a function other PRs also
   edit. Add an explicit !typing guard on the click path so the safety is stated,
   not emergent.

3. Test hardening (also raised by CodeRabbit): assert len(got) == 1 before
   indexing got[0] in the draft-preservation test, so a regression fails cleanly
   instead of panicking.

Tests: TestPermissionFeedbackBackspaceKeepsStagedAttachment (mutation-verified
against the missing guard) and TestPermissionFeedbackRendersNoClickableOptionsWhileTyping.

KRATOSandKRATOS 89bdc6719a fix(tools): read_file recovers a backwards line range instead of erroring (#779)
* fix(tools): read_file recovers a backwards line range instead of erroring

renderReadFileRange hard-failed when end_line < start_line, costing the caller a
whole retry for an arithmetic slip. It was also inconsistent: start_line past EOF
returns a friendly note and end_line past EOF is auto-clamped to the last line —
only a backwards range hard-errored.

Recover it the same way: clamp end_line UP to start_line (read just that line) and
surface the adjustment in the output so it is never silent. Valid ranges
(end_line >= start_line) are byte-for-byte unchanged.

The change is in the argument-validation phase, before any file I/O, so there is
no runtime cost; if anything it saves the agent a wasted retry turn.

Tests: TestReadFileToolRecoversBackwardsRange (recovery + note + reads only
start_line, mutation-verified against the old hard error) and
TestReadFileToolValidRangeUnchangedByRecovery (valid ranges carry no note and read
the identical window).

* test(tools): assert full valid-range output in read_file recovery test (#779 review)

anand + CodeRabbit: TestReadFileToolValidRangeUnchangedByRecovery claimed
byte-for-byte preservation but only checked substrings, so an altered
header/separator or a stray out-of-range line would still pass. Compare the
whole result.Output against the exact expected rendering.

KRATOSandKRATOS 722bb31216 fix(tui): stop the permission card clashing on cool themes (#778)
The focused permission prompt was the only prompt card in the TUI that used
brand/warning colours for its interior, and both read badly on cool themes such
as dracula:

1. The selected option ("Yes, proceed") was filled with zeroTheme.badge — the
   brand chip meant for short labels (" 0 ", " ASK ", " SPEC REVIEW "), a
   full-brightness accent fill. Every other selectable list in the TUI (model
   picker, provider list, / palette) highlights its selected row with onSel/selBg
   instead. The permission card was the outlier, painting a saturated accent slab
   across the row and skipping the card tint every other line composed onto.

2. The card BODY was tinted with permBg, an amber-family wash intended to signal
   a warning surface. It works on the warm default palette but renders as a
   brown-yellow slab over cool themes, and it made the permission card the only
   prompt whose body carries a fill — ask_user, spec review and plan all use a
   transparent body (lipgloss.NewStyle()).

Fix both to match the rest of the TUI: the selected row uses onSel(ink) like
every other picker, and the body drops its permBg fill for a transparent one.
Warning identity is unchanged — the amber PERMISSION badge and the amber-mixed
border still mark it as a permission gate; only the clashing interior fills go.

TestFocusedPermissionSelectedRowUsesSelectionTintNotBrandChip asserts against
palette entries (not hardcoded hex, so it survives a theme retune): the selected
row carries selBg and not the brand accent, the body carries no permBg wash, and
the PERMISSION badge keeps its amber fill so the card still reads as a warning.
