Below 1200px the workspace column folds, and the rule that folded it also hid
its divider:
[data-fold~="rail"] .gutter-l { display: none }
The grip on that divider is the only way to reopen the column — keys.ts has no
shortcut — so the session list left the window with nothing pointing at it. The
reporter's screenshot shows exactly that: the right divider's chevron still on
screen, the left edge bare. 1920x1080 at 175% scaling is 1097 logical pixels, so
this is an ordinary laptop, not a corner.
The rule was added believing the column is removed at that width ("a handle for
a column that doesn't exist"). It is not: .app[data-rail="off"] narrows it to
0px, and :792/:795 style that divider specifically for the collapsed state. The
block's own opening comment already said so — collapse, never remove, or "the
only entry left is an invisible shortcut."
The right column had the same hole for a different reason. Hiding .gutter-r is
right while that column is open, because it lies across a full-width row where a
vertical drag means nothing; it is wrong while the column is collapsed, because
the fold hides the column too and the grip is again the only way back. The rule
now says which state it means.
perf/fold.mjs holds both. The invariant is reachability, not the presence of any
particular control: a folded column must either still be on screen or still have
a grip that can be hit — a relocating column satisfies it, a vanished one does
not. Read structurally (display/visibility/opacity up the chain, then
elementFromPoint, because something painted over the grip fails the user the
same way), and the left column is followed through the click to prove the way
back actually works. It found the right column's half on its first run.
panels.mjs asserted the defect — shown(".gutter-l") === false at narrow widths —
which is how this survived. Corrected to the invariant.
Reported as #9507: "the session list is gone, every launch is a new session."
The second half follows from the first — with no way to reach the list, there is
no way to resume.
rpcCallBudget already exists and its comment already names this failure: "a hang
detector, not a latency assertion ... the previous two seconds failed whenever
the tree was tested at once." It was written for one call site and the other 31
waits kept the literal.
They are all the same thing — every one fails with "never started", "was never
called", "timed out waiting". None is a negative assertion waiting to confirm
something does not arrive, so none of them wants a short deadline; a wait that
fires early reports a hang that did not happen, on a runner that was merely
busy.
TestE2EDeleteActiveSessionDoesNotRecreateFiles failed this way on Windows CI
while the full tree ran: two seconds to cover a server start, a session open, a
provider turn and a tool dispatch. The same test, and the whole suite, pass on
the same platform locally.
Also restores 2.9.0.md to the text its tag shipped. Three commits landed after
studio-v2.9.0 was cut and appended their entries to that file, so it described
work no release contained; those entries move to 2.10.0, which is the release
that actually carries them.
The `ask` tool reaches a person through exactly one wire: the Asker that
EnableInteractiveApproval installs on the executor. Nothing in the tree asserted
that wire was live. An assembly that stopped installing it answers every
question with the headless model-assumption fallback — the run decides for the
user instead of asking, and no gate says anything.
Both directions, because either alone can be satisfied by the wrong thing: a
controller with interactive approval on must put the question out and take the
answer back, and one without must return the fallback and must not raise a
question nobody is there to answer.
Reported as #9509 (2.7.0 fine, 2.8.0 and 2.9.0 not). These pass at HEAD, so they
do not reproduce it — they close the hole that let it go unnoticed, and narrow
where it can still be: not in this wiring.
All three had been red on CI since the work they cover landed, each for its own
reason and none of them a defect in the code under test.
- The ACP approval round trip asserted the tool result equalled "written ok".
A call that changes what the host owes now carries the obligation delta after
its own output, so the assertion reads a prefix: the subject is that the
approved tool ran and reported, not what the host appended to it.
- attach's fake machine still answered `command -v reasonix` in the shape
LocateCommand used before it reported `bin`/`ver`/`flag` lines. The bootstrap
therefore saw no kernel over there, tried to install one, and failed with the
npm sentinel — a harness the far side had outgrown, not a broken locate.
ensure_test.go's fake already spoke the current shape.
- browse's helper resolved the temp dir through its symlink and required the far
side to answer with what it resolved to. On macOS it answers with the spelling
it was handed, so both sides are resolved before they are compared: which
spelling comes back is that machine's business, and the test's subject is
which directory it named. The tests skip on Windows, which is why only CI saw
the first two.
VerificationIdentity kept every segment standing before the check, so
`cd /w && ls -la && go test ./...` and `cd /w && go test ./...` were two
identities that could never supersede each other — and a check that just ran
green is exactly the thing that should replace the unreadable run before it.
Its own doc already said what it meant to keep: context, "a segment before the
check decides where and under what it runs". A listing or a status standing
beside the check decides nothing it proves. The identity now keeps only the
segments that set context — an assignment, or cd/pushd/popd/export/set/unset/
source — and drops the rest, as it already dropped everything after the check.
That is the shell's own account of what changes the environment a later command
runs in, read off the parsed argv, not a guess at what a command was for.
TestSameCheckInADifferentWrapperIsOneItem fails without it.
checkContract carried a lazy write: the first caller to ask what the task owed
captured the baseline the task is held to. Every parallel tool call asks as it
finishes, so that first ask arrives on several goroutines at once — -race
reports the read at final_readiness.go against the write beside it, through
obligations -> finishToolExecution -> executeOne -> runParallel.
Two baselines could overwrite each other, and the baseline is what decides
whether the turn's delivery claim stands.
The capture moves to beginRunTurn, where nothing else is running, and the ask
becomes a pure read. That is also the stronger reading of its own rule: the
baseline must come from the pre-image, before any call could rewrite the
declaration it is taken from. Guarding the write instead would have kept a
mutable field on a path that has no reason to write at all.
TestCancelInsideLargeParallelBatchStopsSchedulingNewTools and
TestBuildRegistersUsableHistoryAndMemoryRetrievalTools both go green under
-race; both failed on it before.
Baseline evaluation ran the toolchain once per captured criterion at the end of
every turn. A broad mutation captures every test file in the tree, so a turn
that rewrote none of them still paid a build per file — the model had answered
and the window sat spinning while the host quietly built.
A criterion the workspace still holds byte for byte was run by the project's own
checks; the overlay exists for the ones it no longer holds. Unchanged criteria
now produce no fact and no build, and the first evaluation that does run
announces the checking phase rather than leaving an unexplained wait.
Splitting the wallet onto its own route added the call to sse.ts and left
apiPaths behind, so the request fell through to the assets and the rail read a
404. The route parity test caught it and had been failing since — in a nested
module the root `go test ./...` cannot see, which is where a red test hides
longest. `make test` now runs the shell and the SDK too.
Five holes let a turn answer the gate that was auditing it. Each is closed by
the same move: the fact comes from what the host observed, never from what
execution was free to rewrite.
- A `go test ./...` quoted inside a here-doc body satisfied a declared project
check that never ran. commandSegments split the raw text on separators, so the
body's lines became segments. SplitOutsideHereDoc drops the body and keeps the
commands beside it.
- A here-doc cost the whole command its decomposition, so a turn that ran its
tests next to one read as having skipped them, and `python - <<PY` walked past
the Delivery gate that refuses `python -c`. The shell tables now read the same
fact permission already reads.
- `cd backend && go test ./...` shared an identity with the root run, so a green
root suite cleared a red subdirectory one. Canonicalisation now drops spelling
and plumbing, never the context a segment before the check decides.
- An unclassified receipt took the pipeline's exit status for the check's, so
`go test ./... | tail` could clear the failure it was hiding.
- missingMutation was wired end to end and never incremented. An unprovable
change is now a debt only observation settles; a check that runs afterwards
speaks for the state, not for the effect.
Obligations are derived by diffing the ledger, never announced: nothing can emit
or erase its own debt, and the delta reaches the model with the result that made
it. Delivery stops refusing opaque interpreters — what the host cannot audit is
recorded unproven and owed, not blocked at the door.
Criteria the task began under are the host's. Declared checks keep a captured
baseline the current declaration cannot retract; test criteria are captured from
the pre-image before any call that could overwrite them, and evaluated through
`go test -overlay` against the code that replaced them. A rewritten test passing
answers for itself, not for the bytes it replaced.
Also: the credentials error names the file it reads instead of an env var it
never consults, the MCP rail shows the way out instead of the endpoint's words,
and run --metrics carries the turn's own verdict beside its outcome.
t.TempDir removes its directory once. On Windows a deleted file keeps its
directory entry until the last handle closes, so a test that finished while the
OS still held something it wrote fails the removal as non-empty when every file
is already gone. Measured at ~2% of session saves, always inside 10ms.
testenv.TempDir is a drop-in whose cleanup retries RemoveAll and logs the one
that never frees rather than failing the test. The desktop module cannot import
it, so its 15 files keep t.TempDir.
A turn request has six orthogonal parts — input, the line carrying its
@-refs, display text, the pre-edit original, the resolver, the output format —
plus a sync/guarded switch. Those were spelled out as 40 entry methods:
runRefTurnWithRefsFormat, runScopedRefTurnWithFormat,
runTurnLoopWithFrozenImagesRawDisplay, and so on down the cross product. The
branch that picked between them assigned closures over three variables in two
if statements, which is a data table written as control flow.
Approval had the same shape at smaller scale: requestApproval,
WithReason, WithReasonOptions, FreshDecision, DecisionWithOptions were one ask
and one grant, spread over five names by which arguments a caller happened to
have.
Both collapse to a value. approvalRequest carries tool/subject/args/reason and
the two postures that may answer instead of a human; refTurn carries the ref
turn's parts; orchestratedTurn already existed and now reaches the entry
points. 27 entry methods remain, and the port keeps its public shapes: no
frontend contract moved.
Collapsing the loop layer found a bug. runEditedGoalLoopWithImageRefsRawDisplay
was a copy of runTurnLoopWithPreparedTurn, and when e4e6936b1 taught a turn to
finish what it owes instead of showing a card that only says "continue", it
taught only one of the two. A resubmitted edit that ended short of verification
still got the card. The copy is gone and the edit rides the same loop;
TestEditedResubmitFinishesWhatItOwes fails without the fix.
One asymmetry is left as it was, not fixed blind: the edited branch of
turnLoopRunner still does not bind the turn's output format, where the ordinary
branch does.
Capabilities named 56 methods in one interface — skills, hooks, MCP, network,
shell, permissions, sandbox, config repair, extension UI, provider catalog. The
whole point of the driving port is that a frontend sees only what it drives,
and this one interface undid it: a pane listing skills was handed
SavePermissionRules and SaveSandboxSettings along with them.
It splits along the lines the frontends already use: SlashDispatch, Skills,
Hooks, MCPControl, RuntimeSettings, Extensions. CapabilityScope moves to
Lifecycle, where the workspace it describes already lives.
What that exposes is ACP. EditorAPI embedded the whole surface, so the
transport could reach skill authoring, hook editing and sandbox rules it has
never called. It now names the three ports it drives, and the segregation
guard puts its unused count at zero, from three.
No implementation changed; *Controller satisfies every new sub-port.
A diagnostic, to be reverted. release-signing keeps refusing the studio
line's requests with nothing but "Invalid request to SignPath API", and
the connector returns no validationResult to say which gate closed.
test-signing-ci-approval carries the same two checks — verifiesTrustedBuildSystem
and verifiesOriginPolicy — against the test certificate, so one run says
whether the origin setup is what refuses the line or whether it is something
only the release policy applies.
scripts/verify-windows-authenticode.ps1 came from the retired desktop line and
still described it: six executables at the payload root, a portable archive with
current.json and versions/vX.Y.Z/, and a mandatory -PortableArchivePath the
studio workflow never passed. Studio ships one executable. The step is gated on
HAS_SIGNPATH, which has never been true, so nothing has run it — turning the
gate on would have signed both artifacts and then failed on the verification
that was supposed to confirm the signatures.
It now checks what studio actually ships: the one executable in the payload, the
installer around it, and the copy inside the portable zip — that copy compared
by hash against the signed payload, because a signature check alone would pass
an archive packed from an earlier build that was also signed. The workflow
passes the archive path it was already producing.
Verified on a real Windows host across three cases: all three artifacts signed
and matching passes; an archive holding a different signed binary is refused as
a mismatch; an unsigned payload is refused as missing a signature.
The external services block was the only thing on the rail painted red: an
inset rule down its left edge, and the endpoint's whole complaint set in --err
under it. Three lines of red in a column of grey readouts reads as a dialog
that got stuck in a dashboard.
The rail already has a rule for this and it is written into .drow's tone: the
mark that carries "this is broken" takes the colour, the words describing it do
not. The pip stays red and the count in the heading still says how many; the
rule was a third way of saying the same thing, and the reason now sits at the
size and weight every other secondary line on the rail uses.
Reaching a machine is the gate that rarely fails. A cold connect then installs
a kernel over there, and that is where it stops — and every one of those stops
arrived as an English sentence with no code on it, because HostState.Err is a
string and the refusal-path guard only watches internal/serve. One of those
sentences told the reader to set serve_install = npm, which was not a control
the window had.
internal/remote/bootstrap now has sentinels for the ways putting a kernel there
fails, grouped by what the reader would do about each rather than by which
function produced it: npm is missing, npm installed outside the login PATH, the
local binary is for another platform, nothing is left to try, what landed will
not run, serve never reported a port. desktop/next maps them to dotted codes
through one table, and the wording for each names the next move. Two tests that
matched on error text now match on identity, which is the point of having it.
The host form grows the controls those sentences point at: the install strategy,
the jump host, and the env var holding a password. They were already stored,
already on the wire and already carried through a save — only the controls were
missing, so telling someone to change one was telling them to edit TOML.
And a connect no longer has to be the thing that discovers all this. Probe reads
what a first connect depends on in one session, changing nothing over there:
which machine it is, what is installed, whether npm runs, and for each install
route whether it is open — a closed one carrying the same code a real failure
would have refused with. `reasonix remote test` walks it after the dial it
already did, and every host row in the window has a button for it.
The wallet balance had been reaching the frontend for months with nothing
rendering it, and it rode GET /status — which the desktop polls four times a
second while a turn runs. A network round trip on that clock is what the reader
ends up waiting on, so it answers on its own route at its own pace now: pane
mount, turn end, or a click on the label. Four answers stay apart rather than
collapsing into one number. A provider with no balance_url draws nothing at all
(204) — most providers have none, and a dash there reads as a number that failed
to load. A value standing in past its freshness says how old it is. A wallet
that could not be read carries a code for which failure it was, never a zero.
internal/billing picks its decoder by endpoint host, the way the price catalogue
already does. Moonshot's wallet was silently broken: its response parses as
DeepSeek's shape without erroring and decodes into an empty balance, so a funded
account read back as unusable. A response in nobody's shape is ErrUnreadable now.
Plan.tsx and panels/Overview.tsx had no importer at all. The plan block the
design calls for was written, styled and never mounted, so the plan lived only
in a tool card that scrolls away and a tab you have to switch to. Plan is back
where the design put it, beside the changed files; Overview is deleted with the
six translations only it used.
Both defects were invisible to every check the tree had, so both get a guard.
route_parity holds internal/serve's routes against vite.config.ts's proxy list:
a route missing there answers with the SPA shell, which is indistinguishable
from a broken endpoint and only happens in dev. orphan.test.ts fails a .tsx
nothing imports.
`perf/i18n.mjs` reported six missing English strings in the storage panel. All
six were there. Chinese is a valid JavaScript identifier, so a catalogue can
write either `"占用": "Space used"` or `占用: "Space used"`, and en_storage.ts
writes the second — while the guard's key regex only ever matched the first.
Seventeen keys were invisible to it, six of them reachable from a `t()` call,
and those six came back as "no translation for this".
A permanently red guard is the same failure as a permanently green one: it has
stopped saying anything about its subject and is only saying something about
itself. Nobody could use this one to catch a real miss, because it was already
failing. It reads both spellings now, and the set it builds is 1276 keys —
exactly `Object.keys(EN).length`, which is the check that says the fix is
complete rather than merely quiet.
The regex stays a regex, so it grows the one thing a text-reading guard owes
its reader: it says which lines it could not parse. Any two-space line that is
neither a spread nor a comment and produced no key is listed and turns the exit
code red, so a third spelling cannot be silently rounded down to "missing"
again. Matched by start offset rather than by text — one key's text can be a
prefix of another line, and comparing text would let exactly the line this is
meant to catch pass as read. Confirmed against a computed key, which it names.
The vitest catalogue test never saw any of this: it imports EN and asks the
object, so it was right all along. That is the lesson worth keeping — a guard
that parses source text has to be able to report its own blind spots, because
the tie-breaker is not always sitting next to it.
The composer's border carries a light that travels around it while a turn is
running. Its own comment says the light means "it is moving" and must go out
when the run stops — and it does go out: `.glowring` is `opacity: 0` unless
`.pane[data-run="running"]`. Only the opacity ever stopped. The 150px radial
gradient inside it kept running its `offset-path` loop sixty times a second,
re-rasterising inside a `mask-composite: exclude` layer, from the moment the
window opened until it was closed. `offset-distance` is not a compositor
property, so the whole of it lands on the main thread.
On a 400-turn conversation with nothing running at all: 44.0% of the main
thread and 1.11 renderer cores, against 11.4% and 1.02 with the animation
removed. Unthrottled the same pair is 9.8% / 0.13 cores against 2.9% / 0.07.
That is the shape #9481 reports — CPU that stays high with the window merely
open, and drops the moment it is closed rather than when the work finishes.
The fix is to let the animation and its visibility be the same condition:
paused by default, running only under the selector that already makes it
visible. Idle goes 44.0% -> 11.4% throttled and 9.8% -> 2.9% unthrottled. The
running case is unchanged, which is correct — that is when the light is meant
to be moving, and attempts to make that half cheaper (stepped timing, layer
promotion, a smaller blob) did not reproduce across runs, so none were taken.
perf/idle.mjs is the guard the contract was missing. The performance criteria
covered streaming, scale, and switching, and had nothing to say about a window
that is doing nothing — which is how one always-on animation went a whole
release unnoticed. Two assertions, one structural and one measured: every
running animation must be on an element that can actually be seen (zero
opacity anywhere up the chain, hidden visibility, or no box is a defect no
matter how fast the machine is), and the net cost of animation on an idle
window — the same machine measured again with animation off, subtracted — must
stay inside a budget, so machine speed cancels out and the number means the
same thing here and in CI. The light is asserted in both directions: welding
it shut would otherwise pass. selfcheck.mjs takes it, and both new assertions
were confirmed to go red for the right reason.
Opening a workspace on a remote host meant editing the host book first: type
the path into settings, save, then find the row in the sidebar. Nothing below
the sidebar required that. /remotes/open hands its workspace straight to attach,
and bootstrap resolves ~, an absolute path, or one relative to the login home —
an arbitrary folder has always been openable. What was missing was a way to say
one: the rows the sidebar can click are the union of the host book and the far
kernel's own tree, so a folder written down nowhere could not be named.
attach.Pool.Browse holds the link and nothing above it. Attach's two halves are
already separate — holdLink dials, holdSpace bootstraps — so listing a folder
takes only the first: no reasonix installed, no serve started, no forward bound.
That is what makes picking work on a machine this build has never run on, which
is exactly the machine a folder is being picked on. The connection is released
on a timer rather than at the answer: stepping into a folder is a second call,
and a link dropped between the two re-dials — which on a passphrase-protected
key means asking for the passphrase again.
GET /remotes/{host}/dirs answers folders only, spelled by the machine that owns
them. The parent comes back as a value rather than being cut from the path here:
a Windows host answers a mac with a drive letter and backslashes, and neither
side's path rules describe the other's. A folder larger than the cap says so —
a silent truncation reads as "what you are looking for is not there".
The link layer separates a mistyped path from a link that is down, because only
it sees the file protocol's answer: remote.no_such_folder and
remote.folder_unreadable come from errors.Is against the stdlib sentinels that
pkg/sftp normalises to, not from reading a message. A missing folder arriving as
a bad gateway sends someone to check a connection that is up.
Picking opens, and opening writes the folder into the book. The far kernel's own
list is the better home for it, but it can only be read while something is open
over there — the book is what survives a cold start. What is recorded is the
path the far side resolved, not the one that was asked for: ~ is expanded over
there, and recording the other spelling would list one folder twice. The write
is skipped when the book already holds it, so the common open does not rewrite
the user's config file.
A list that only grows needs an exit, so the folder list gets two narrow
endpoints of its own. The settings page replaces a whole row, which is right for
a form holding every field; a sidebar control that knows one folder must not, or
it sends back blanks for the address beside it. Only a folder this window wrote
down offers the control — one the far kernel reports is that machine's own note,
and dropping it here would take away a row that comes back on the next read.
wire-parity takes port/remote.ts: RemoteHostView, RemoteListing and RemoteFolder
are declared against the desktop's hand-written copies. RemoteHostEdit is left
out on purpose and says why — the kernel still accepts the singular workspace an
old row was saved with, and the page that writes one deliberately sends the list
alone. An under-filled request is not a picture that cannot be read.
Closes#9475
SIGNPATH_API_TOKEN is a repository secret, so it is already readable from this
workflow — the token gate alone would turn signing on the moment this file
merges, and the policy still trusts only main-v2. The next tag would then break
on a signature that cannot be granted yet.
STUDIO_SIGNING_ENABLED is the half no secret can express: SignPath's console has
been told to trust this line's origin. Merging is inert until it is set.
Studio's Windows artifacts were unsigned by construction — the production
SignPath policy trusted exactly one origin, protected main-v2, so a build from
this branch could not request the certificate. The workflow said so and left it
there. On a managed Windows endpoint that is not a SmartScreen warning: the
installer is refused at CreateProcess, and Windows reports it as "cannot access
the specified device, path, or file", which reads as a permission problem and
is not one.
The desktop line's mechanism comes over whole, adapted to what Studio ships.
Signing is two-staged for the reason main-v2 states: signing only the finished
NSIS container leaves reasonix-studio.exe unsigned on disk after installation,
which is precisely what reputation and ML heuristics quarantine. So the
executable is signed while it is still a loose file, the packages are rebuilt
around those exact bytes, and the container is signed second — with the
artifact configuration verifying the payload's signature rather than trusting
this workflow's ordering.
studio-build.sh grows the seam that makes that possible: --windows-payload
builds what a user runs and stops, --windows-package builds the zip and the
installer from a payload directory it is handed. The one-shot platform path
composes the two, so an unsigned build and a maintainer's local run are byte
-identical to what they were.
.signpath/ carries this line's own contract — branch studio, workflow
release-studio.yml — and cmd/signpath-contract validates and fingerprints it
before anything is built, so a widened origin fails at the gate rather than at
the signing request. Its branch pin is studio rather than read from the file it
checks: a guard that reads its own answer out of its subject cannot guard.
Signing engages only when SIGNPATH_API_TOKEN is set, mirroring the APPLE_* gate
— forks and token-less runs still build, unsigned.
This cannot take effect on the repository side alone: the release-signing policy
in SignPath's console still trusts only main-v2, and until the studio origin is
added there every request from this workflow is rejected. See the PR body.
TestApplyLocalSkillLinkMode asked runtime.GOOS, and asked it after asserting
resp.OK — so a machine that cannot create a symlink failed on the refusal the
tool had correctly reported, rather than skipping. Windows allows symlinks under
Developer Mode or elevation, which the platform name cannot tell apart from a
plain account, so the check is now the read three cases in this file already
make: try it, and skip on the error the filesystem gives back. A Windows host
that can make one now runs the case instead of skipping it.
Also ignore *.exe~ — what the linker leaves when it cannot replace a binary that
is still running, which on Windows is every rebuild while Studio is open.
The shelf's pills were ordinary flex children, so a row one pixel short of
fitting squeezed them instead of wrapping — and Chinese breaks between any two
characters, so 计划 came apart into two lines and took the row's baseline with
it. A pill is now its label's width or nothing: the shelf wraps, which .row
already allowed, and the send button's auto margin keeps it at the right end of
whichever line it lands on. Verified from 980px down to 320px: one line, two,
then three, with nothing broken at any of them.
The model pill is the one control with no width of its own — a gateway can
publish an id longer than the shelf — so it gives up characters before the
shelf gives up a line, and the ref it was shortened from stays in the tooltip.
Closes#9455
The attach pool has always keyed spaces by workspace and named a forward per
one; the far kernel remembers every folder a pane opens and answers /tree with
all of them. Only the book could name a single directory, so nothing could say
the second one — and cold, before a pane exists to ask through, the sidebar had
just that one row.
RemoteHostEntry gains workspaces beside workspace, folded by WorkspaceList into
one default-first list so a row that only ever set the old field is a list of
one rather than a case every reader repeats, and an upsert makes the head of
the list the default the CLI still connects to. The sidebar shows the book and
the far tree together: a folder added here and never opened over there stays,
and one opened over there appears without being written down here.
The [remote] renderer moves to render_remote.go — the section is one subject,
and the function it came from is already the longest in the package.
Closes#9459
The kernel replays a pending ask/approval to every client that attaches, and
the window then overwrote its items with what /history rebuilds — where the ask
tool call is deliberately drawn as nothing, because ask_request carries the id.
The pane sat at 等你决定 with nothing on screen to decide and the queued turn
behind it never dispatched. A prompt is not part of the record; it is the run
stopped waiting on an answer, so it rides across the rebuild. prompts.ts also
gives one its kernel id, so a replayed frame is the same card rather than a
second answerable copy, and an answered one is not reopened by the frame log.
SandboxSettings carries effectiveBash beside effectiveWriteRoots, so the pane
draws what the confiner will do rather than what was configured: an unset mode
enforces everywhere but Windows, which runs unconfined however the file reads.
The segment for a mode this host cannot run is visibly dead and carries its own
reason — `disabled` alone kept the hover of a live control and then swallowed
the click, which is what was reported as broken. Enforce-without-a-backend
refuses by code rather than by a hand-written sentence, and the SandboxSettings
mirror is declared to wire-parity so the next field cannot drift.

Accumulated working-tree work, committed as found; the tree builds and passes at
the tip.
The palette, the picture-less sky and the ray/cloud tints the Studio design was
drawn against, as a pack the kernel serves rather than something a user has to
install to see the app as designed.
Accumulated working-tree work, committed as found; the tree builds and passes at
the tip.
RunStrip was one strip carrying every reading. It splits into panels — Overview,
Runtime, Cache, Cost, Context, Agents, Files, Jobs — with derive.ts doing the
walk once in the pane and kit.tsx holding the shapes they share, so a reading
that grows does not widen a row every other reading has to live in.
Alongside: Sky draws the backdrop a theme pack asks for rather than placing a
picture, Nav takes the icon rail, Timeline and Task give the trajectory and a
subagent their own views, AccountRow the account, and prefs/keys/trailing carry
the state, the bindings and the tail the panes were each keeping privately.
perf grows three scripts: selfcheck, which pushes a false assertion into every
guard to prove the guard can still go red; sourcemap, which turns a minified
frame back into a source position; and switchprof, which samples the cost of
opening a long session. look and verify grow the assertions they were missing.
This is accumulated working-tree work, not written in the session that committed
it; the message describes what is here rather than the reasoning behind each
piece. The whole tree builds, vets, typechecks, and passes its tests and
repolint at the tip.
Both stand for a failure that stayed silent while every other gate was green.
tokens.mjs: a var(--x) with no fallback has to name something someone assigns.
CSS drops the whole declaration when it does not, and the property falls back to
whatever was inherited, which reads as the design. Two of those were live in the
tree — the connection prompt's scrim named a --bg that has never existed, so it
had blur and no dimming at all, and the usage panel's --fg meant its text colour
never landed. Both lists are read from source, the stylesheets' own `--x:` and
the per-element ones JSX writes into style, because a hand-copied list rots.
shipped.mjs: dist must be newer than everything under src. A build can succeed,
print its tick, and compile something else — this tree has more than one process
on it, and a stash that put it back to HEAD for forty-eight seconds was enough
for one build to fall inside the window and produce the previous release. The
window then loaded it and the whole interface reverted, while the tests stayed
green: they read the source. Timestamps rather than marker strings, because
"the artifact is older than the source" is one sentence that cannot rot.
Both were mutation-tested the way selfcheck.mjs asks: a var nothing defines
turns tokens.mjs red, touching a source file turns shipped.mjs red, and a
PERF_SRC that points nowhere fails loudly instead of passing quietly.
Six things, and four of them were defects rather than taste.
The window opened on a blank page. index.html now paints a boot screen before
the bundle it would otherwise wait for exists: the wordmark written on letter by
letter in gilt and settling to ink, the sky the theme packs draw, and one line
saying the kernel is being reached. main.tsx hands the window over when the
intro has finished rather than after a counted delay, so a fast kernel does not
flash it and a slow one is what it is for. It carries its own palette because
tokens.css is a bundled import that does not exist yet at that point.
Settings becomes a sheet over the workspace instead of a second full-screen
window. That removes the duplicate: .prefs-hd used to be a title bar too, with
its own drag region, its own traffic-light inset and its own window controls.
The window frame is .chrome and only .chrome now, and the veil starts below it,
so the window can still be dragged, minimised and closed while settings is
open — a modal that traps the window buttons is not a modal. Its contents list
grows the design's marks and groups, and reports what each section is worth:
storage in bytes, usage in tokens over the window Usage itself opens on, the
build running.
The segmented control was a full-width strip of underlined tabs at all sixteen
call sites. It is an inset track with the selected cell lifted out of it, which
is a control's size rather than a navigation bar's, and section headings shrink
to overlines so the rows under them carry the weight.
Then the defects:
- A theme's picture is body::before at z-index -2, and it is visible only
because an uncoloured html hands the canvas to body's background. The boot
screen's stylesheet had coloured html, which takes the canvas over and
demotes body's to an ordinary element paint — landing on top of the picture.
A wallpaper simply stopped appearing. boot.test.ts fails any rule that puts a
background on html or :root, because nothing else was watching that file.
- The cost panel's sparkline was a black rectangle. Spark's fill and stroke
rules were written under .rate, the throughput row's scope, so the cost
panel's copy matched none of them and an SVG with no fill declared is filled
black. The colours belong to the mark; only the throughput row's geometry
stays scoped. The panel's wrapper stops sharing the component's own class,
which is what let a wrapper's layout land on the drawing inside it.
- A picker's menu jumped to the bottom of the window before fading out. Its
anchor name hangs on [aria-expanded="true"], which flips the instant the menu
is asked to close, while the menu is still on screen; with no anchor left to
resolve, an anchor() without a fallback invalidates the whole declaration.
The fallback is the same 100% the non-anchored rules have always used.
- Every view swap cross-faded a snapshot of the entire document. Only the
swapped element carries a view-transition-name, which swap.ts says in a
comment, but the root kept its own default name — so closing settings dipped
the whole window and brought it back. :root opts out.
The preview itself is a sheet in the same family, portalled to the body because
under a wallpaper the side column carries a backdrop-filter and that makes it
the containing block for anything fixed inside it. Rows in the changes list
become buttons carrying git's own letter, coloured by what it means.
--fg was read six times in the usage panel and has never been defined, so those
declarations were dropped and the colour fell back to whatever was inherited.
It is --text. bytes() ran to MB and stopped, which is how a 9 GB total read as
"9318.4 MB"; it runs to TB, and Storage stops carrying a second copy of the
rule that i18n/format exists to hold.
The rail lists what the tree differs by, and until now that was all it could
say: a path and a porcelain letter. What the file actually differs by lived
only in the tool events of the turn that wrote it, so a change made before this
session — or by a shell command no event describes — could be named and not
read.
gitstatus.Diff answers for one path. It measures against HEAD so a staged edit
and an unstaged one read as the single change they are to a person. An
untracked file has nothing in HEAD to compare with and is diffed against the
null device instead: that is the only way git prints it without first writing
to the index, which a read must not do.
The path arrives from a client, so safeRel keeps three shapes away from git —
outside the tree, absolute, and readable as an option — and every invocation
puts it after "--" as well. ErrPathOutsideTree is a sentinel because the caller
has to tell a bad request from a broken repository; over HTTP they carry
changes.path_outside_tree and changes.diff_failed, and the frontend has words
for both.
root goes through gitcmd's dir parameter rather than an "-C" argument. gitcmd
hardens a subcommand it can see at args[0], and --no-ext-diff/--no-textconv are
exactly the flags a diff against someone else's repository needs: a repository
config can name a program git then runs during an ordinary read.
The desktop shell needed telling too. Its route table lists families rather
than leaves, so /changes/ joins the prefixes — without it the shell answered
/changes/diff with index.html and the preview would have failed on a body that
parses as HTML. TestEveryRouteTheKernelRegistersIsRouted caught that before it
shipped, which is what it is for.
routes() moves to routes.go. serve.go sat exactly on its file-size budget, so
one more registration line broke it, and the budget is not there to be widened:
the route table is every path this server answers, which is a subject of its
own rather than a section of the file that assembles the server. serve.go drops
from 1459 lines to 1365.
packagesFor took the directory of a declared file with filepath.Dir, which
on Windows answers `internal\control`. That is not a pattern go test can
match, and it sorted the list wrong on the way out, because a backslash
outranks a slash — one root cause, two symptoms in the same assertion.
The gate itself runs on ubuntu, so nothing it gates was affected; its test
runs on the whole matrix, and has failed windows-latest since the gate
landed. A declared glob and a go package pattern are both slash-separated
whatever the host is, so both reads move to path.
Windows groups a taskbar button and routes a toast by the process's
AppUserModelID, and the Start Menu shortcut has to carry the same one or
the notification is dropped. The two calls that set both lived in the
retired shell. When it went they lost their caller, and the sweep that
deletes unreferenced exports took them — leaving internal/notify sending
toasts under an identity nothing claims, and six unused findings on the
GOOS=windows lint leg, which the sweep's own host-GOOS run never saw.
Restored and called from the window's startup, before the first window
exists, which is when Windows reads it. The call site carries no build
tag: identity_other.go already answers for every other platform.
A host decorates its pane's sink once — the status icon's fold, desktop
notifications, usage counters — and builds the controller on it. That
decoration lived only at the build call site, so every path that rebuilds
the controller wired the replacement to the bare broadcaster and dropped
it: a model or effort switch, an extension reload, a workspace change,
and saving a provider credential, which is the first thing a new install
does.
Nothing corrected it afterwards. A switch is refused while a turn runs,
so the last event those observers saw was the previous TurnDone, and they
stayed on it for the pane's whole life. The tray reported "nothing
running" through a fourteen-minute turn.
The Server now carries the sink its controller emits into, so the thing
that rebuilds owns it rather than the call site that happened to build
first. build and rebuildWith move beside the options they read; the file
they left is over its ceiling and had no room for the addition.
The test fails on the old code for both rebuild paths with the reported
symptom: the pane's decoration sees none of the replacement's events.
Reported in #9448. The paint ordering fixed in db030ad0 is a real defect
but needs two panes changing at once, and is not what that report shows.
Both have failed every run of CI's windows-latest job since the corpus
landed, and neither is a flake.
gen-topo-cycle timed each call with signal.alarm. Windows Python has no
SIGALRM, so the grader raised while installing the handler, before it
graded anything. A daemon worker thread keeps the semantics exactly —
_Timeout on a hang, the original exception re-raised, so the cyclic case
still reads ValueError — and cannot hold the interpreter open at exit.
gen-csv-quotes compared cli.py's stdout against an expected string.
Windows Python writes CRLF in text mode, so that comparison could never
hold; the carriage returns come off first, because the grader checks the
fields and not the host's line endings. Its mktemp template also read
TMPDIR, which under Git Bash is a Windows path — the rest of the corpus
asks for a bare mktemp -d, and now so does this one.
The modernize pass reports two findings on this file, and they fail both
`make lint` and CI's lint job. A strings.Index used to slice a prefix off
is strings.Cut, and ranging over a Split is SplitSeq.
Two panes changing at once take their folds under the lock and report outside
it, so the two reports could reach the icon in the opposite order. The one that
lost left the icon describing a state the tracker had already moved past, and
nothing corrected it: the fold reports only what changed, so a wrong paint
latched until the next real change. A pane running a fifteen-minute turn is
fifteen minutes of a tray that says nothing is running.
Painting is now serialised and describes the fold as it stands when it paints,
so a report that lost the race repaints the truth instead of overwriting it.
The test fails on the old code with the reported symptom exactly: the icon
shows Working:0 while the tracker holds Working:1.
Reported in #9448.
The review gate read one index for two questions — what the change set is,
and how fresh a review of it must be — so a later harmless write moved the
window past everything before it. A sensitive edit followed by a README write
scored Low and dropped the whole structured-review demand.
UnreviewedMutationBaseline now answers the first question and the latest
mutation still answers the second. It advances per review kind, so an accepted
review does not discharge security_review's obligation with it.
Alongside, the parts of that gate that promised more than they did:
- A blocking verdict is honored at every role setting, and review subagents
submit the typed report everywhere. A verdict a caller must act on carries
an identity, not a sentence. The nudge runs everywhere too; the hard failure
stays in Delivery, since outside it no report is no block either way.
- Medium no longer demands a structured review "or" host-proven
self-inspection. That was no alternative — the reader there is the author —
so the cheap side was always taken and the demand never bound. The real
requirement inside it moves to the self-inspection gate and grows teeth:
inspect every changed path, fresh per path, not one of them.
- warn findings were collected into a slice nothing read. They now reach the
user, and they are collected from any review the turn ran rather than only
from one the gate asked for.
- verificationGapResult.advisory carried no text and reached nobody while two
comments called it reported. The waiver it stood for is right and stays; the
flag wearing a message's type is gone.
The review and security-review bodies stop hardcoding git: fileutil owns one
declared store table, environment reads it, and a skill subagent's prompt now
carries the workspace fact its parent always had. They also drop the ~12-call
self-cap, which was well under the host's real budget, and split the burden of
proof — adversarial about what must be read, conservative about what may be
reported. A pass is a negative claim and owes what any other does.
complete_step: manual evidence no longer stands alone in a turn that already
has receipts. The evidence ablation arm reaches the tool schema, so the two
arms stop paying the same prompt and the A/B can answer for the contract
rather than only for the gate.
agentgraph's own account of why it exists is that every consumer folds the same
deltas, so the graph a headless run reports is the graph the desktop draws. The
desktop's fold is a second, hand-written copy — the type and the merge both —
and nothing checked the two carried the same fields. Adding one field to the
kernel this week meant remembering to add it in two more places by hand. The
next person will not remember, and neither toolchain will say so: they are
compiled separately and meet only at runtime, over JSON.
wire-parity reads the Go struct's json tags against the TS interface's
declarations and fails either direction — a field one side sends and the other
cannot read, and one it reads that nothing sends. A field the encoder skips is
not on the wire and is not demanded, so an internal field costs nothing.
The pairs are declared rather than inferred, for the reason the sensitive paths
are: no spelling tells a mirrored contract from a struct that merely carries
json tags. Only the graph is declared today, because it is the one that claims
both sides fold identically.
agentgraph's own account of why it exists is that every consumer folds deltas
with the same Apply, so the graph a headless run reports is the graph the desktop
draws. The desktop's fold is a second, hand-written copy of it, and nothing
checks the two carry the same fields — a wait cause published by the kernel and
unknown here is a node the picture cannot say anything about.
The type is what holds it: dropping it fails the typecheck through this fold and
its test. The merge line is consistency with every other field rather than a
defence — an absent key already survives the spread.
Rendering is left alone. Every site that would show it, and the strings it would
need, are mid-change in the working tree, and this is one row away whenever that
lands.
Queued was one word for three constraints with two remedies. Two are session
settings — the total sub-agent ceiling and the concurrent-writer ceiling, which
binds a writer while total capacity is still free — and the third is a write
path someone else already holds, which no setting releases: only disjoint paths,
or an edge that orders the pair. The scheduler was the only thing in a position
to tell them apart, and it answered in a sentence built for one caller's error
message, so nothing downstream could.
WaitCause joins the graph's vocabulary beside NodeState and Grant, canStartLocked
returns it instead of prose, and an acquire that has to wait reports it once —
after the unlock, because the callback reaches a sink the scheduler must not be
holding its mutex for. The cause survives the run starting, the way the stamps
do: the state says running now, this says what it waited on.
The fan-out price splits with it. One figure summed every wait between ready and
running while its name said the concurrency ceiling caused it, so a member held
behind a claim was quoted back as a reason to raise a ceiling that would not have
moved it. Two figures now, because there are two answers.
Both fan-outs take the same pair of hooks from one place: the two moments only
the scheduler can report are published by one thing rather than copied into each
producer.
parallel_tasks takes a model and an effort per task, so two members of one group
are not necessarily the same worker. The graph drew them as if they were: a
fleet node carried the profile, model, effort and grant its item ran under, and
these carried a label and nothing else. A reader asking why one arm of a fan-out
cost more than another had nothing on the picture to answer with — the tool
offers the distinction and the graph erased it.
The identity is resolved once, in the loop that was already building the labels,
rather than again inside each item's goroutine.
A run can be told to finish its list by two host prompts: the readiness
continuation, and the Goal FSM's "signaled complete but issues remain". Only the
first was ever taught which actions the completion guard lets through. The Goal
path still ended with "use todo_write/complete_step to mark done" — the one
action the guard refuses — so a run reading it beside the requirement it embeds
was handed the open door and the shut one in a single message, and heard about
neither turn exit.
Both now append one string. Owning it once is the point: the failure here was
two copies drifting apart, and a third copy is what let them.
That third copy was the requirement's own. Every path that shows a requirement
to a model goes through one of these two prompts, so its ways-out sentences were
read twice, in two wordings, inside one message. Its other readers — the ACP
turn outcome, the recovery card — are host- and user-facing, and were being
handed instructions written for a model.
The argument contract read which fields a call supplied and never what it put in
them. A field with the right name and the wrong kind was therefore neither
unknown nor missing: it passed every check the host makes, and the answer came
from Go's unmarshaler — "cannot unmarshal string into Go struct field .evidence
of type []agent.blockedEvidence". That names the host's types rather than the
caller's mistake, and it costs the round trip that discovers it. A live run
spent one that way on conclude_blocked before it even reached the two it spent
on the field names and the evidence itself.
The schema already declares each property's kind and the arguments already carry
one, so comparing them is the same structural read the contract was doing on
names. A mismatch now refuses the call before permission is consulted, for the
reason the missing-field case already refuses: execution was never possible.
A null is not a mismatch, and a property whose schema declares no type leaves
the question unanswered rather than broken — the contract may only report what
the schema actually said. The hint drops "it accepts ..." for a pure mistype,
because the field is accepted and listing the accepted names answers a question
nobody asked.
The contract is read after proxy resolution, so a tool reached through
use_capability is compared against its own schema and refused the same way; a
test pins that, because reading the call order is how you get it backwards. An
on-demand MCP tool declares no properties and the contract stays silent on it. A
connected one is compared against its server's schema — the same trust the host
already places there by refusing a call that omits a field it marks required.
addTurnExitTools registers the two ways a turn ends on the model's terms rather
than the host's: ask for a decision only the user can make, conclude_blocked for
a task that cannot be done as specified. The host's own account of the ways out
named only the second. So a turn that ended by putting a question to the user
was continued straight past it, and the run — told in the host's voice that
there were exactly three doors and that none of them was "wait" — answered the
question itself and said so in the transcript.
Naming ask closes it, in the requirement and in the continuation alike, with the
rationalisation it has to beat spelled out: not having heard back is not an
answer to assume one from.
The escape that used to exist was an accident. The stall counter compared the
gap against the best round so far, and a run waiting on an answer could not
shrink it, so two rounds handed control back. Scoring the continuation against
the previous round's signature instead removed that side effect without
replacing it with a deliberate one.
Nothing here reads the wording of what the model said. The signal is the
declared turn-exit set, which the host was already free to name and did not.
The fleet plan proved a dependency DAG and published it, and the scheduler that
decides which item actually runs never saw it: an AcquireRequest carried a write
claim and a label and no position in the graph at all. So a slot went to whoever
queued first, which is how the head of the longest chain ends up behind leaves
that unblock nothing — and that wait lands on the run's makespan one for one.
It is the loss fanoutMetricsOf already prices as wall above the critical path:
measured every run, acted on by nothing.
The plan now measures each item's rank, the longest chain of dependents below
it, and carries it to the acquire, where the pump drains waiters heaviest first
and keeps arrival order within equal weight. That covers every grant after the
session's slots are full, which on a fan-out wider than the ceiling is nearly
all of them.
It does not cover the first fill, and sorting the launch loop does not either.
Which of a burst of goroutines reaches the scheduler first is the Go runtime's
decision: launching heaviest-first captured 41.8% of the ideal first-fill weight
against declaration order's 51.9% at a ceiling of two, and tied at one and three
— never better, sometimes worse, because the runtime favours the goroutine
created last. The loop is left alone and says why.
A run also queues before it builds rather than after. It used to construct the
whole child — registry, runtime, and the transcript that holds a store lease —
and only then join the line, so a fan-out wider than the session ceiling held
one open per item it had not started, and every millisecond of that setup was
billed to a concurrency ceiling that had not caused it. Foreground runs hold the
slot from before the transcript exists; background ones still return a job id
first and queue inside the job. Deriving the request moves to slot.go, the file
that owns the acquire.
Delegation makes three claims and upstream-edge can only settle one: both of
its tasks are strict chains, so their speed-up is 1.00x by construction and no
scheduler decision is observable in them. fanout-width fixes a shape whose
three research items share nothing, which leaves the session concurrency
ceiling as the only thing deciding whether they overlap — so the serialised arm
needs no ablation flag, only max_subagent_concurrency = 1.
Each subsystem retires nine of ten modules and names the live one in entry.py,
so a grep over the markers returns ten candidates and answers nothing.
inboxEventSink hand-forwarded seven optional sink capabilities and missed
three, so every child run's receipt died one wrapper below the sink that
accounts for it. A benchmark then reported four fleet members as a task one
agent had solved by itself, and the whole delegation section rendered empty
while its owning tests stayed green — which is the failure AuditForwarder's own
doc comment already described. Embedding it is that comment's remedy: a channel
added there now reaches this wrapper without editing it.
The graph already carried every stamp a benchmark needs and nothing folded
them, so delegation was reported as a count of children and never as what the
shape bought. Work against wall is the speed-up; the critical path is the floor
the declared dependencies impose, and wall above it is scheduling loss; slot
wait is what the concurrency ceiling cost members with nothing left to wait for
— the one wait no edge on the graph can draw.
The effect test now pins the stamps themselves. Without them every figure here
folds to zero, which reads as a fan-out that took no time rather than as a
measurement that never happened.
The pane already replayed the trajectory into the graph reducer, but the wire
log dropped every graph_delta on the way to disk, so a reopened window drew a
run that had waited on nothing. A dependency and an adopted answer exist
nowhere else in the stream: unlike a tool mark, they cannot be re-derived.
Studio never called crashreport at all — only the CLI did — so not even a Go
panic was recorded. That is the smaller half. Every Studio crash reported so
far has been a fatal signal inside GTK or WebKit, which no recover can reach:
the runtime writes that trace straight to the descriptor, so a tee on
os.Stderr would keep every log line and lose the only one worth keeping.
So stderr is redirected, not wrapped. The window opens a log under
<home>/logs and dups it onto the descriptor, keeping a copy of the terminal
first when there was one, so running Studio from a shell still prints. One
log per launch, newest few kept: a crash is reported after a relaunch, never
during the run that produced it.
Linux uses Dup3 rather than Dup2 — linux/arm64 has no dup2 syscall at all.
Windows says it cannot instead of pretending: it resolves the handle its
crash writer uses once, at start, so moving os.Stderr afterwards would move
the window's own logs and not the trace. There the log still gets those.
crashreport can now name the host it came from. sanitizeReport overwrote
Source with "cli.go" unconditionally, so a Studio report would have arrived
claiming the CLI and sent whoever read it to the wrong code. The set is
closed rather than free-form, and the CLI's own reports are unchanged.
Motivated by #9408, where the crash is inside cgo and the Go traceback stops
at gtk_main(). The only trace anyone has is there because the reporter
happened to launch from a terminal.
A census of the 78 fields, by where each is written rather than by reading
the names: 37 are bound once in New and never reassigned, and the rest change
while the session runs. Both kinds sat in one list, so c.policy and c.turn
read alike at every call site and only one of them can change under you —
which is the question anyone reaching for c.mu has to answer first.
The 37 move into an embedded controllerDeps. Embedded because field promotion
keeps all ~720 c.field reads resolving unchanged: the point is to make the
lifetime legible at the declaration, not to rename the package. Controller's
own field list drops to 42.
Two fields that qualified by the write test stayed out on purpose. commands
is an atomic.Pointer and externalFolderToolRefs sits with the mutex-guarded
map it belongs to; filing either under "never rebinds" would read as "not
concurrent", which is the opposite of true.
repolint reclaims struct-state 5, file-size 123, function-size 5 and essay 6
— the scalar debt recorded against controller.go was exactly this mixing.
Tests, vet, and -race on the package all pass unchanged.
The memory panel has always told the reader that saving "records a new
revision; the old one stays". Nothing in the UI could show that history or
step back into it: GET /memory/revisions and POST /memory/restore were both
served, both had Controller port methods behind them, and the frontend never
named either — the promise was there and unverifiable.
An entry past its first revision gets a history control; opening it lists the
revisions behind the current one with their dates and bodies, each restorable.
Restoring appends a revision rather than rewinding to one, which the panel
says, because a restore that dropped later revisions would destroy the very
version a reader opened the history to compare against.
The fixture kept only the latest revision, so a panel driven by it would have
shown an empty history and proved nothing; it now keeps what a save replaced,
the way the store does.
Verified in the running Studio through CDP: editing an entry produces
revision 2, the history lists revision 1 with its original body, and
restoring it leaves the entry on revision 3 carrying revision 1's text with
both older revisions still listed.
REASONIX.md calls these paths the ones where a wrong change is "a hole in a
boundary". Measured, they were the least-tested part of the kernel rather
than the best: shellsafe 59.3%, shellparse 63.6%, sandbox 69.4%, netclient
47.2%, against a tree median of 76.5%. The code deciding what the agent may
execute and reach had the weakest evidence that it works.
The gate reads the same `sensitive:` bullets the runtime reads for its
review requirement, so a path is declared once and gets both effects — there
is no second list to fall out of sync. Floors are per declared path and
measured from the coverage profile per file, not per package, because
`internal/control/approval.go` is sensitive while the package around it is
not; measured on its own it is 93.9%, which no package number would show.
Floors ratchet in the opposite direction to repolint's budgets and for the
same reason: raising one is free, lowering one needs -allow-drop and a
reason in the PR. They record what is there today rather than an aspiration,
so the gate is green on arrival and only fails on a regression.
Verified by removing one shellsafe test file: the gate reports 47.3% against
its 59.3% floor. Adding an unrelated `sensitive:` line puts that path under
the gate with no other change.
Two fixes and one sweep, all from the same audit.
The process history catalog was never closed. boot's cleanup releases LSP,
plugin hosts, the runtime scope and session temp; the catalog's own
Flush/Close had lived in the retired shell and were left to two test files.
It is process-wide, shared by every pane and workspace, so it closes at the
process boundary next to the usage catalogs, not with any one controller.
Queued index writes are drained first — the reopen after an unclean exit
re-scans every root instead.
The sweep removes 57 exported functions with no reference anywhere in the
tree, tests included, plus the private helpers that fell dead behind them.
Iterated to a fixpoint: deleting a function exposes the next one, and both
the orphan rule and golangci's unused ran again after each round until
neither reported anything.
The rule learned two things from being wrong here. Methods are now out of
scope: chatTUI.Init is bubbletea's tea.Model, no file in the tree names it,
and proving that needs type information an AST pass does not have — the
first attempt at this sweep deleted it. And an orphan tests still reference
is reported differently from one nothing references, because they need
opposite fixes: repair.PrepareFileUpdate is a cross-package fixture eight
test files build state with, and deleting it was the second thing that
attempt got wrong. Only the unambiguous half is deleted here; the 124
remaining stay recorded.
The last-known-good snapshot died because deleting one frontend left its
callee behind with the implementation, the tests, and the doc comments all
intact. Nothing in CI reads "has a caller", so the tree stayed green for
eight days while a recovery path read a file no longer written.
The orphan rule counts callers across the whole tree, which is the part a
single-module analysis cannot do: desktop/ is its own module and a real
consumer of internal/, so a scan that stopped at the root module would call
its APIs dead. Two things deliberately do not count as callers — tests,
which are what keep an orphan warm and green, and doc comments, which are
what make one look wired. Both are checked by tests here, because both were
true of RecordHealthyConfig.
Test-support packages are exempt: their exports cannot move into _test.go,
so having no production caller is their normal state.
328 existing orphans are recorded as the ratchet baseline, not fixed here.
Verified against the original accident: reverting the fix from the previous
commit trips the gate on RecordHealthyConfig by name.
Recovery reads a snapshot nothing had written since the Wails shell was
deleted. That shell held the only two RecordHealthyConfig calls, so from
908bc3ec0 on the read paths in config/load.go and config/unparsed.go kept
restoring whatever config was current that day. On this machine the file
was 16 days and 161 diff lines stale, and `doctor repair --apply` would
have written it back over the live config without saying so.
The shell proved health with "the window became visible", a signal only
Wails had. A successful assembly proves the same thing for every frontend,
so the record rides BuildRuntime, which reload goes through too, and CLI /
serve / Studio inherit it instead of each re-wiring it. Options.Version is
the host declaring a real installation; embedded and test assemblies leave
it empty and write nothing. The writer is already idempotent — unchanged
config hashes to the existing snapshot — so every start can call it.
Both recovery paths now date what they are about to trust: the load warning
carries the snapshot's age, and doctor repair prints it before --apply
rather than after.
Options moves to its own file, which is what pays for the new field: boot.go
drops 128 lines and the tree reclaims 176 file-size, 21 function-size, 15
essay and 3 complexity of budget.
Verified against a real binary: assembly writes the snapshot and stamps the
ldflags version, a second run adds none, and a broken config reports
"--apply would restore a snapshot 16 days old".
govulncheck reported seven reachable call paths into the 1.5.0 advisories —
the feishu adapter's socket, and two readers that reach a compressed frame
through io.ReadAll. It now finds no vulnerability this code calls.
collectSink appended to an unsynchronised slice and handed the slice itself
back. That held while a turn was the only thing emitting. It stopped holding
when the inbox gained a change listener: the store notifies from its own
goroutine, so six tests began failing under -race — both stacks inside the
helper, one appending while the other read.
It appends under a lock and returns a copy taken under the same one. The race
was never in the controller; the harness had no way to say so.
One cost line mixed the rounds that carry the session with the single-purpose
calls beside them — titles, digests, classification. They scale differently, so
a run that got dearer said nothing about which half moved.
The split is by usage source and named the other way round: the conversation
sources are listed, so a source added later counts as auxiliary instead of
falling out of the split with nobody noticing.
Failing the pristine seed is only half of an authored task. A grader that can
never pass is indistinguishable from one with no solution: every attempt scores
zero, and a corpus of those teaches that nothing is ever accepted. Tasks that
ship a reference solution are now checked against it, and a generated task that
cannot satisfy its own grader is deleted rather than patched.
The generated tasks live apart from benchmarks/e2e on purpose. That suite is
the instrument every cross-version comparison is read against; mixing new
tasks into it would change what those numbers mean.
Recorded runs are only training data once someone decides which ones were any
good, and the run report already holds that verdict. sft mode reads the two
together: the report decides what is exported, the trajectory's run header
supplies the prefix each sample was produced under.
A run without a header is skipped rather than exported against a guess at what
its prompt and tools were.
A trajectory held the event stream and nothing from the request side, so a
reader could see what the model said and never what it was asked — the system
prompt and the tool schemas the rounds were sampled against were simply gone
by the time anyone read the file.
The header carries both, plus the hashes usage events already report, so a
reader can prove the pair belongs to the rounds that follow instead of
assuming it from the file it was found in. It is written by the frontend that
owns the recorder rather than forwarded through the sink chain, which keeps it
out of the optional-capability contract every wrapper would otherwise carry.
NormalizedToolSchemas exports the exact bytes ToolsHash covers, so the hash is
recomputed from what was stored rather than from a second serialization.
bindRunSession collects what a headless run does to attach to its session,
which had grown into four steps inline in runAgent.
Opt-in metrics carried the anonymous install id so the dashboard could show a
deduplicated daily user per signal. Keeping that answer meant keeping a row per
install per signal per day — ~28M of them — and the 30-day COUNT(DISTINCT
install_id) over that table was the database's entire read bill: the primary
key leads with `date`, so each query could prune only the window and scanned
the whole table, eight signals an hour, ~5.4B rows a day for one module.
The client stops sending the id, the worker stops writing and creating the
tables, the hourly rollup that existed only to make that query survivable is
gone, and the dashboard's users/opens toggle goes with it. The aggregate
tables keep the same signals as event counts in ~180k rows.
migrate-drop-metric-users.sql drops the four retired tables. Deploy the worker
first — it stops creating them at runtime, and a DROP before that is rebuilt on
the next request.
Dropping a folder from outside the workspace mints a token and registers it
with the read tools' resolver. That is where the mapping to a real directory
lives, and the grant is read-only — handing bash the real path instead would be
a writable way into it. So the token is not a path, and bash's answer for one is
the shell's own: "No such file or directory".
A model that was handed the token in the same turn believes that. This session
did: it ran `ls` on the token, then `find` over the whole home directory, and
concluded the reference was virtual and the file did not exist — while the file
sat on the Desktop the entire time, reachable by read_file all along.
Bash now recognises a token before running and says what it is and which tools
resolve it. Recognition, not a guess about what a word might mean: the resolver
is asked, and its keys were minted by the host.
The four preflight refusals repeated the same four assignments before returning,
so they are one call now — adding a fifth check left the function shorter.
The posture a pane opened in was read off whichever runtime happened to be
first in the hub's order. Closing the conversation the person had set to auto
or yolo therefore reset the next one to ask — an approval prompt on a tool
they had already waved through, with nothing on screen saying why — and with
every pane closed there was nobody left to read it from at all. The same line
dereferenced Server on a remote pane, which does not have one.
The hub holds the stance instead: seeded from the runtime the host adopts, so
it is the launch setting until someone changes it, and written by the composer
switch, which already persisted the same choice to config for the next launch.
It no longer depends on which panes are still open.
The approval endpoints move next to that setter, where the rest of the
settings surface lives.
The icon drew a rounded square with a notch and a corner badge — a mark that
appears nowhere else in the product, so the tray was the one place Reasonix
was a different logo.
It is now RMark.tsx's three paths, carried over in the 16-unit space the SVG
draws them in and rasterized against a distance field: reading a stroke as a
capsule is what gives the round caps and joins without drawing either.
Mood is colour and nothing else, each hue the one meaning the palette already
assigns it — ghost is neutral, net is running on its own, accent is needs you.
The lightness belongs to neither theme, because a notification area is a
background this process cannot ask about: all three clear 3:1 against white
and against near-black.
The tests hold the two drawings together, so a path or a stroke weight that
moves in the frontend fails here instead of leaving the icon on the old glyph.
Studio never carried a SingleInstanceLock, so every double-click of the
launcher started another process over the same data home — several windows,
each binding session leases the others were already holding.
The lock is keyed to the data home rather than the executable: an installed
build, a portable one and a canary all write the same sessions, so they have
to find each other, while an explicit REASONIX_HOME stays its own instance.
The prefix is Studio's own bundle identifier, so this never answers the 1.x
desktop's lock.
REASONIX_DEV still waives it, and run-studio.sh now passes that through
`open --env` — LaunchServices does not inherit the shell's environment, so
without it a dev launch would be handed to an installed window.
Closes#9412.
`droppedRef.Image` carried `omitempty`, and false is a bool's zero value, so
the field left the JSON at precisely the value the composer needed: every file
that is not a picture answered with silence. The page read that silence as an
image — the check was `image === false`, and `undefined` is not `false` — and
drew an empty thumbnail labelled "image" over a .md file.
POST /attachments never had this: it writes its answer through a map, which
omitempty does not touch. Only a path dropped onto the window went wrong.
Both sides now state it. The field is always present, and the composer asks
whether it is an image rather than whether it was denied: a missing field falls
back to the file glyph, which still shows the name.
Two separate things were painting over a wallpaper nobody could see.
The rail: its 54px hit box is pointer-events:auto and sits over the transcript's
right edge, so any control that lays out to the right — the rewind entry is one
— lost its right half to it. The width is now a token both sides read, and the
transcript keeps clear of that column instead of fighting it for z-index, which
would only have traded a dead button for a dead stretch of track.
The wallpaper: three background rules were unconditional, and rail + panes +
side tile the window exactly, so the image was sealed under them. Two rules
written for it had therefore never once fired — .app cleared a path nothing
took, and .flow's 88% scrim, meant to catch prose over a photo, sat behind a
panel that was never transparent. With the panes clear they finally show, and
what they do is not what was wanted: the rails are down to a thin frosting,
the empty-page halo no longer tints itself from --surface (which reads as a
black fog in the dark theme), and prose carries its own shadow instead of
cutting a slab out of the picture.
Closing the metrics rail did not survive the window: nothing wrote the choice
down, so every launch opened it again. Two things had to change together —
the fold-away helper kept the wide-window value in a ref seeded to `true`, so
even within one session, narrowing the window and widening it back reopened a
rail the reader had shut.
The rail still opens by default. What is remembered is the reader closing it,
and only a deliberate close is written: folding away because the window ran out
of room leaves the wide-window choice alone.
The window process does not act on SIGTERM, so the pkill before `open` matched
the old instance and then left it running. Every `make studio` opened another
copy on top of the last, and they accumulated for as long as the machine stayed
up — two were live here, one of them a day old, before this was noticed.
Ask with SIGTERM, wait a beat, then insist.
Ranks say which column a node sits in and nothing about its row, so the
order the deltas arrived in decided it. Wires crossed for no reason a
reader could act on, an edge spanning a column was drawn straight over
whatever cards stood in the middle, and the same run redrawn came out
different.
Layout moves to its own module so the arithmetic can be checked without
rendering anything, and gains Sugiyama's two missing steps:
- Ordering. Each column is swept by the median of its neighbours' rows,
and only a sweep that lowered the crossing count is kept, so a round
cannot make the picture worse.
- Waypoints. A long edge reserves a thin row in every rank it crosses,
which is what keeps it off the cards it flies over.
- Columns are centred against the tallest rather than hung from the top,
where a lone node read as a step that ran early instead of one that
ran alone.
The panel also reads the kernel's new facts: a queued node says so
instead of sharing "not started" with a node nothing has reached yet,
the summary counts the two waits apart, and the detail strip carries
slot wait beside run time.
Folding is indexed rather than scanned. The graph is the one piece of
session state that only ever grows, so a findIndex per node and a scan
per edge made the cost of one delta the size of the whole run.
The graph declared StartedAt and EndedAt and no producer ever filled one,
so every consumer's timing fallback was dead code and a run's own order
survived only as the order its deltas happened to be published in.
Waiting for a slot and holding one were the same word besides. A fan-out
the session concurrency ceiling was throttling drew identically to one
where every item started at once — and which of the two it is decides
whether raising the ceiling would buy anything.
- agentgraph gains StateQueued and Node.QueuedAt. Terminal() had to learn
the new state: a queued node reported as settled leaves a reader no
longer waiting for the answer it is still going to get.
- SchedulerPolicy.OnStart fires once the slot is held, which is the only
moment the wait can be read from. acquireSlot moves to its own file and
becomes the single place that reports it, for both the foreground and
the background path.
- fleet and parallel_tasks publish queued, then running, then settled.
An item now settles the moment it settles rather than when its group
ends: a long fan-out used to draw every finished worker as still
running until its slowest sibling returned, which is the whole time
anyone is watching it.
Reported as Studio never raising the ask card: the model kept answering with
"ask 无交互响应（fallback）" and telling the user to go fix it. It was reading
its own tool result back. A subagent's ask found no asker and returned the
headless fallback - the text written for autonomous runs, which says in as many
words that no interactive user answered.
The root executor has an asker: EnableInteractiveApproval wires the controller
in as one, and every interactive frontend calls it. A child never did.
newAgentServices binds each collaborator from Options and there is no Asker
among them, so SetAsker is the only way in and only the controller ever calls
it - on the executor and the planner it holds, never on anything they spawn.
The gap was silent because the fallback is a plausible answer rather than an
error.
The call context already carries the right answer and nobody was reading it.
RunSubAgentWithSession is the one construction boundary every child goes
through, and by the time it runs, the context says whether a question can be
put to anyone: a delegated run has a parent blocked on it and a person waiting,
so exactly one question can be outstanding; fleet items and parallel tasks
build their context with the asker dropped on purpose, because a question from
one of many has no reader who knows which asked it; a background job runs under
a job context with no call on it at all. Inheriting from the context therefore
needs no flag and no policy - the three cases already differ where it matters.
Both halves are tests now, because "silently answers itself" is what this class
of bug looks like and neither half fails loudly. The construction moved to its
own file rather than growing task.go, which is 1200 lines past its budget.
Reported as connecting to a Linux server failing with "这次请求没能送到内核
（HTTP 502）" and nothing else. The request had arrived. The kernel had
answered, at length, and two layers threw that answer away between it and the
window.
Opening a pane over there is two hops: attach the link, then ask the kernel now
running on the far side to open a runtime. The link half already codes its
failures - a changed host key is not a network hiccup, and identify() in the
desktop says so. The second half did not. farRequest returned fmt.Errorf with
the far side's status and body flattened into a sentence, writeErr found no
code on it and fell through to http.Error, and a sentence is exactly what the
repo's own rule says an error a caller must tell apart may not be. A dead link
and a kernel that answered with a refusal are different problems with different
next moves; only a code carries that.
They have codes now. A transport failure is remote.unreachable, the same
condition the proxy beneath already reports through a different door. A far
kernel that answered is remote.kernel_refused, carrying the host and whatever
it actually said - falling back to the status line only when the body was
empty. Three writeErr call sites pick both up without changing.
The other half is the hub port, which asked for JSON and discarded anything
that was not. SseHttp was fixed for this once - users reported
"/providers/edit: 500" - and the hub was left reading res.json(), so every
plain-text answer from every hub route reached the window as a status and a
path, which reason() then renders as the request never having been sent. It
reads the body as text once and parses optionally, the way its sibling does.
Only a genuinely empty body may now claim nothing came back.
Reported as MCP not connecting automatically: twelve enabled servers, each
listing the tools it brought, every one of them reading "not connected" with a
Reconnect button beside it. Nothing was broken. That is what a healthy install
looks like, and the panel had no word for it.
Enabled config MCP is catalog-first by design. Boot registers each server's
cached toolset as placeholders and starts no process; the first real tool call
drives the handshake, and a fast server completes it in the same turn. So
host.Servers() is empty for all of them, every row falls through to the branch
for servers with no live connection, and that branch had two answers - off, or
idle - for three situations. The comment there already claimed to tell "switched
off" from "lazy and not needed yet"; the code did not.
The catalog answers it, not the host. A server whose tools are in this
session's registry can be called right now, whatever its process is doing, and
that is the question a status row is actually asking. MCPCatalogTools counts
the registry's MCP bindings in one pass - lazy placeholders included, because
they carry the server name like any other binding - and configuredState turns
that into standby, idle or disabled.
The panel says 待命 · 首次调用时启动 for standby and offers 立即连接 rather than
重连: nothing failed, so nothing is being retried. The mock's cache-hit fixture
moves with it, or the harness would keep showing the state this fixes.
Reported as storage settings reset to C: after upgrading Studio, with the
original location then impossible to choose again because it "needs an empty
folder". Two defects, and the second is the one that traps a person: whatever
loses the pointer, the data is still sitting on the other drive and there is no
way to say so.
The reset is the installer. studio.nsi asks for admin and the finish page runs
Studio itself, so the app inherits the installer's token; on an account that
elevated by entering someone else's credentials, %APPDATA% then resolves to
that administrator's profile and the first launch after an update reads a
config.toml that never heard of the user's relocation. It launches through
explorer.exe now, which is already running as the signed-in user. The exe
manifest is asInvoker, so only that one launch was ever affected - which is
exactly the launch the report describes.
The trap is that a relocation was recorded in exactly one place. A directory
now says what it is: a move writes .reasonix-root.json once the copy is proved
and before the configuration is told, so a marker means this folder is
complete, and it is removed from a location the root leaves. A preflight whose
target already holds this root's own data plans an adopt instead of a refusal -
the pointer alone, nothing copied, verified or reclaimed, and nothing at the
old location deleted. The plan reports what stays behind rather than letting it
go quietly missing.
Structure decides, never resemblance: the marker names the root, or - for a
root that declares what it owns - the folder holds those entries and nothing
else. A root with sole occupancy and no marker cannot be told from a stranger's
folder, so it is refused rather than guessed at. A folder left with only the
marker of a root that moved on is an empty target, not data to adopt.
RecordRelocatedRoots marks the locations a configuration already chose, so a
folder an older build moved data into becomes adoptable after one launch; it
follows the importers' rule and does nothing when the environment redirected
this run's roots.
While in there: PlanMove measured the whole source directory, so a state root
sharing its folder with home counted config.toml and the credentials into a
move that never copies them, and the progress bar could not reach the end it
was measured against.
Clicking a node showed what the kernel knew about it and stopped there. What a
reader wants next is the call itself — its arguments, its output, the reasoning
around it — and the transcript had no way to be pointed at one. Only user
messages carried an anchor in the DOM, because only the rail had ever needed to
find something.
Tool cards now carry the id the graph names them by, nested children included,
which is where a fan-out's nodes actually live. Nothing else reads it, so losing
it would fail silently — the button would switch tabs and do nothing — and that
is what the new test is for.
The rail's two-pass landing becomes one routine both callers share: scroll to
the block first, because the card may sit in one that is not mounted and has no
node to scroll to, then put the element itself under the reader and flash it.
The rail lands on a message, the graph lands on a call; same passes, different
selector.
The request is a counter, not an id, or asking for the same node twice would
land once. It is held rather than spent while the pane is hidden: a hidden pane
has no geometry, every rect reads zero, and the scroll goes nowhere. That also
makes the caller's ordering harmless — the view transition defers what it is
given, so setting the tab and the request in one commit is right, and holding
the request is what makes it right even when it is not.
The panel counted delegates. It could say four were running and never which of
them was blocked on which, because the list it was drawn from had already
thrown that away — the kernel now publishes the structure, so there is finally
something to draw.
A rank is a column: everything in it was free to run at that moment. Width is
concurrency and length is a chain, which is the difference a list renders
identically. Ranks are memoised with a separate in-flight set rather than one
visited set, or a node reached twice through a diamond reads as a root and the
whole picture flattens.
Edges are told apart by line, not by colour. Solid with a filled head means the
upstream answer went into the dependent's context; dashed with an open head
means the pair was ordered and nothing travelled — which is exactly what the
measurement arm produces, and drawing them the same way would say the two runs
were the same run. Reuse is a mark on the node, because an adopted item runs
nothing at all and would otherwise be indistinguishable from work that was paid
for. The state is a word on every card as well as a colour, so none of this
depends on telling hues apart.
The two questions a list cannot answer are the ones the cards lead with: a
blocked node says what it is waiting for by name, and the header says how many
of the fan-out actually ran. A separator that a node id could contain is a bug
waiting for an id with a slash in it, so pairs are keyed by encoding rather than
by joining.
The structure was being re-derived in five places and survived in none. A
fleet's dependency DAG lived and died inside one Execute call — the dispatch it
emitted carried a prompt and a profile, so depends_on never left the process at
all. The persisted sidecar recorded a parent link and nothing else. The event
stream implied the rest through id prefixes. By the time any of it reached a
reader it was a flat list of children, which is why a panel could count
delegates and never say which of them was waiting on which.
internal/agentgraph is the vocabulary, and it is a leaf: nodes, and edges that
carry an identity rather than leaving a reader to match words. depends and
context are two edges on purpose. The measurement arm orders its endpoints
while delivering nothing between them, so a single edge type would describe an
ablated run and a real one identically — the same reason an error a caller must
tell apart carries a sentinel rather than a sentence.
The other half of that rule was already being broken on disk.
InheritedContext.Upstream was a bool: it recorded that some dependency's answer
opened a run, and a reader asking which one had nowhere to look. It names them
now, and a sidecar written while it was a flag still decodes to "there were
sources, unnamed" rather than to nothing.
fleet and parallel_tasks publish what preflight already proved, before any of
it runs — an item that never executes emits no tool events to infer a state
from, and an adopted answer emits none at all. That collapses three copies of
the same five-state vocabulary into one and two identical group classifiers
into one, so a group's progress card and its graph node can no longer disagree
about how the fan-out ended.
A node is the call it names. Timing and output stay on the tool stream and a
frontend joins them by id, rather than the kernel publishing the same clock
twice under a second naming scheme. internal/boot asserts that at the frontend
sink through the real Build assembly: a scripted two-item fleet with a
dependency in it, and the edge has to arrive.
Studio could already say something mid-turn — the composer routes it through
steer, and the row on screen carries the receipt it can be taken back by. What
it could not do is see the queue. The pending rows are minted by the client on
its way out, so they say only what this window sent: reload the page and they
are gone while the entries are still in the manifest, still due at the next tool
boundary. A line the CLI queued, or a second window, was never on screen at all.
So the kernel had ten inbox endpoints and the frontend read three of them.
Editing, reordering, retrying a blocked entry, re-freezing the files one quoted,
holding delivery — all of it existed, with no way in. The panel above the
composer is that way in.
The queue arrives the way the workspace tree and the checkpoint list already do:
an event says it moved, and the content is read back whole. sessioninbox.Store
has had OnChange since it was written and nobody had ever registered one — the
notify path ran into an empty listener slice. Registering it there rather than
at each mutation is what makes this true of every mutation, including the ones
the kernel performs on itself when a turn consumes a steer.
InboxChanged carries nothing. It is tempting to put the snapshot on the wire and
save the round trip, and that would make every client's queue a function of the
frames it happened to receive — a reconnect that missed one leaves a panel
describing a queue that has since changed, and the manifest's checksums and blob
names would be on the wire for no reader. One authority answers instead, and a
frontend that has just reloaded is in exactly the same position as one that has
been connected all along.
adoptInboxLocked exists because there were two places opening a store, and a
listener registered in one of them is a listener half the sessions do not have.
Two smaller things the work needed.
The transport had four verbs and the update endpoint is a PATCH, so it has five.
The contract test that checks the frontend only calls paths this package serves
reads those verb names out of the source: without patch in that alternation the
new call was not unserved, it was unchecked. Confirmed by pointing it at a route
that does not exist and watching the test go red.
Editing opens on the entry's full text, not its preview. The manifest keeps a
120-rune line and nothing more — opening the box on that and saving it back is
how an instruction would quietly lose its last sentence. Measured against a
141-character entry: the row shows 121, the box gets 141.
Verified against a running kernel rather than the fixture, with the entries put
there by a second client so the panel had to have read them from somewhere:
three lines queued over HTTP appear in a window whose transcript never carried
them; an external reorder shows up without a reload; reorder, take-back and
release from inside the panel each land and the panel redraws itself; an edit
saved from the box reaches the kernel. That last one also found a defect this
could not have found any other way — an empty queue is items: null on the wire,
which is what a Go nil slice encodes to, and the panel reading it as an array
would have thrown at the moment the queue ran dry, and only then. Normalised in
the port, where one reader knows it instead of every reader having to.
Deliberately left alone: a line this window sent appears both as a pending row
in the transcript and as an entry in the panel. They are not the same statement.
The row is where it sits in the conversation; the entry is what is still owed,
and it is the one that survives a reload. Folding either into the other would
cost the case the panel exists for.
The window is what this version is: the greys came home to the product's own
hue, the activity stream became a rail you can scan instead of paragraphs on
white paper, and the menu bar got an icon that says what this machine is still
doing. Around it, the close button finally keeps the promise its config option
has been making since before this shell existed.
Two things are deliberately not in here. The status icon's own defects — a dead
Win32 pump, a crash on macOS launch — were introduced and fixed inside this
version, so no released build ever had them; the notes say what the icon is, not
what it survived. And fleet's for_each was built, measured against the call it
replaces, and removed in the same span: it never reached a surface, so there is
nothing for a reader to have used.
Studio did not start on macOS. `open` returned and the process was gone, with
nothing on screen and nothing in the terminal — the bundle path hides the
output. Run the binary directly and it is there:
*** Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason:
'NSWindow should only be instantiated on the main thread!'
-[SystrayAppDelegate applicationDidFinishLaunching:]
-[NSStatusBar _statusItemWithLength:]
tray_run_other.go carried a guess about this and flagged it as one: "macOS puts
its status item on the main thread and Wails already owns that one, so handing
the icon a thread of its own — the Windows fix — would be a crash rather than a
dead icon. Neither platform has been run from the machine this was written on."
The first half is right and the conclusion does not follow: nobody was handing
the icon a thread, and the thread it inherited was not the main one either.
Wails calls OnStartup from a goroutine, and the crash frame is m=5.
It is not the ownership conflict it looks like. registerSystray returns
immediately when the loop is external, so systray never takes NSApplication —
nativeStart only allocates a delegate and calls applicationDidFinishLaunching
on it directly, and that is where the status item gets built.
So the defect is narrow, and it is a lone exception in its own library: every
other systray entry point — setIcon, setTitle, every menu mutation — already
hops to the main thread through performSelectorOnMainThread. nativeStart is the
one that does not.
The hop happens here instead, the way this tree already does it. dock_icon
_darwin.m has the same shape for the same reason, and its comment names the same
caller: "the caller is a Wails lifecycle hook that may not be it."
Async, not sync. dispatch_sync would deadlock whenever the main thread has not
reached its runloop yet, which is exactly when a startup hook runs. Nothing
needs the completion: ready() ends by replaying the last state it was given, and
a setter that arrives before the delegate exists is a message to nil.
tray_run_other.go loses darwin from its build tag and the retired guess from its
comment.
Verified with tray at its default, the configuration that crashed: the window
comes up at 1440x900 and the status item is there, titled "Reasonix", its
tooltip reading "Reasonix Studio — 没有在跑的" — which is ready() having run,
built its menu and replayed state, all on the main thread.
The token system was never the weak half. The activity stream was: the column a
reader spends the whole session in had no material at all, while the rail beside
it has hierarchy, the metrics column has data, and the trajectory tab has a
gantt. In light theme it rendered as paragraphs on white paper — a terminal
block, the largest object on screen, carried border-left: 1px and background:
none.
The timeline was already there in structure and absent in pixels. .call has been
a 20px gutter with a stamp and a connecting line since it was written, but the
line was 1px of --hair, which on a screen is nothing. It is 2px now and takes
the category colour that tokens.css had already assigned and never spent —
neutral reads, amber writes, blue network, teal delegation — so a glance down
the gutter says what a stretch of the turn was doing. Sub-steps inside a
delegate panel keep the narrow gutter: two levels at one width is one level.
Blocks get material. .term sinks half a step by mixing --page into --surface,
one recipe for both themes because page already sits under surface in each. The
approval card lifts out of the flow on an amber wash, and only the one still
waiting: :has(.apv:not([data-sealed])) drops it the moment you answer. Amber
says exactly one thing in this vocabulary — it needs you — and it had been
reaching only as far as the buttons.
Wall-clock becomes a bar beside the number it already prints. It is horizontal,
which was not the first design: drawn down the gutter its length would be
bounded by the card's own height, so a 64s step with two lines of output either
pushes the layout around or gets silently compressed — and a meter that shrinks
when it runs out of room is a meter that lies. Across a header row there is no
such constraint. The mapping is logarithmic because the span is three orders of
magnitude, and the bars right-align against the duration, so a ragged left edge
down a column is the turn's time distribution.
A turn now starts at a visible boundary. Not a new Item type: the user card is
already the anchor the rail jumps to, and UserCard.tsx already records the
decision that turns carry no number, because the rewind entry sits on the card
itself and there is nothing to match up by eye. It gets a rule and some room.
The right column stops being nine equal blocks with nine equal separators, which
reads as an unfinished form. Group boundaries fall on cost, progress,
environment and output, and the first block of each is recognised by the
data-b it already carries — no reordering, no new attribute.
One piece of the plan is deliberately not here. Highlighting the command line
inside a terminal block was going to be .term-l:first-child, and the first line
is not the command: Term splits text on newlines, real shell output routinely
opens with output, and past 300 lines the block is not split at all so there is
no .term-l to select. Guessing a role from a position is the thing this tree
keeps retiring. Doing it properly means telling the renderer which line is the
command, which is a different change.
Second half, found by the sweep the previous commit repaired: 55 light-theme
findings, and they were the design's own rules going unenforced.
--ghost was calibrated against the wrong surface. The comment said "on the
--raised it actually appears on"; it appears on --raised once and on --page 768
times, because rail, side and chrome are all painted in it and it sits a step
darker. The soft tier stopped at 4.03. It is 53% now (4.52 on page), and the
comment says which surface and why. normal and strong already cleared it and are
untouched; dark measures clean on every surface it lands on and is untouched.
--accent is a fill and --accent-ink is the reading value — tokens.css says so,
and 32 rules used the fill as text anyway. In light it clears nothing: 4.07 on
its own wash, 3.91 on page, 3.80 on overlay, while the ink is 4.98 or better
everywhere. --warn is the same hue tier and had 13 more. Only text colours move;
borders, fills and shadows keep the base. In dark the ink is the base, so both
sweeps are light-only.
Two singletons around them. The slash menu's selected row mixes its own tint
rather than using --accent-wash — deliberately, and the comment explains it —
but at 12% the ink on it reached 4.40, so it is 9% and the row is no less
selected. And white on --accent sat at 4.4977, which is not 4.5; #A7690C to
#A6680C is one step of a hex digit, invisible, and lands it at 4.56.
Verified on the real shell against fixture data, both themes, every surface the
sweep can reach: 55 and 45 findings become 0 and 0, with truncation, spill,
offscreen and unnamed-control all empty and no runtime errors.
getComputedStyle now hands back oklch() and color-mix() verbatim, and parseC
dug the numbers out of whatever string it got. Three components that mean
lightness, chroma and hue were read as if they were r, g and b, so every
judgement compared two colours nobody had painted: 1037 findings on a dark
sweep, all of them "#01004B on #00004B", a pair that appears nowhere in the
token table.
A gate that fires on everything is worse than no gate for the same reason one
that fires on nothing is — both bury the findings that are real. This one had
gone all-red, and the 55 genuine light-theme findings underneath were
indistinguishable from the 807 it invented.
The fix is to stop parsing. Paint one pixel with the computed value and read it
back: whatever the browser resolved is what gets measured, and the probe needs
to know nothing about colour syntax it will have to keep up with. Dark drops
1037 to 45, light 807 to 55 — and those 55 were real, which is what the next
commit is about.
One other correction while in there: the root background fell through to black
when html was transparent, because a fully transparent colour still parsed to
four numbers. It is only adopted now when its alpha says something was painted.
A vision host rejects an oversized image as an unsupported *format*. Measured
against api.deepseek.com/anthropic on 2026-08-24: 8192x1000 is accepted,
8193x1000 is not, and neither is 1000x8193 — the limit is a single side, while
total pixels (8000x8000 passes) and bytes (a 12 MB PNG passes) are not bounded
at all. The message names webp, png, jpeg and gif, so the reader spends the next
hour confirming the file really is a PNG. It is. It is too wide.
Worse than the wrong question: the rejected user message stays in history and is
resent every turn, so one attachment ends the session. Nothing in the tree
stripped it and retried; ProviderErrBadRequest had no consumer at all.
compressForVision scaled on side length but forwarded the original whenever it
could not: an undecodable mime, a header it could not read, and — the one that
fires here — anything past the 50M-pixel decode limit. A long diagram is exactly
that shape, so it skipped the 1568 budget and went out full size.
The budget is now the gate. internal/visionimage owns the only judgement, and
what leaves it has both sides within MaxDim or does not leave: no vendor number
is written down anywhere, because 1568 already sits below every host's ceiling
and a declared 8192 would be one vendor's answer imposed on the rest. What
cannot be proven to fit is refused with ErrUnfit, an identity a caller can read,
and the reason names the dimensions and what to do about them.
It is a package rather than a control helper because MCP tool results are the
same hole reached from the other side — toolResultImage validated base64 and
size and never looked at dimensions — and internal/plugin cannot import control.
Both callers now ask the same function.
Around it, a turn's attachments stop being three loose values. turnImages says
what the model got, what a delegate could get, and what nothing got, which
retires orchestratedTurn.imagesResolved: a resolved turn is a non-nil pointer.
The headless entry points compose through imageRoutingPrefix like the
orchestrated one does — they bound the attachments but dropped the note, so a
model with an unreadable attachment was told nothing and went off to write its
own OCR script.
Refusing is only half of it; saying so is the other half. The user gets the
reason and the file, and the model is told an attachment exists that it will
never see, so it does not answer as though nothing was attached.
Verified against the real endpoint, one arm each side of the budget:
12000x5000 (60M px) refused locally, "past the 50000000-pixel decode
limit ... shrink it first"; the model relays it and
suggests sips -Z 7000. The turn completes.
20000x1000 (20M px) downscaled to 1568x78, sent, answered correctly.
12000x5000 sent raw 400 unsupported image — what shipped before this.
Two deliberate gaps. The 50M-pixel decode limit is unchanged, so an 8000x8000
image the host would have taken is now refused locally; raising it trades
against decode-time memory and wants its own measurement. And a session already
carrying a rejected image still needs a rewind — this stops the poisoning, it
does not clean up after it.
Test fixtures that were PNG signatures over zero bytes are now decodable PNGs:
an image whose dimensions cannot be read no longer travels, so a header-only
fixture asserted nothing.
Nothing held docs/SPEC.md against its Chinese companion, which is how 3.13 lost
a table row and 3.14 fell three commits behind before anyone noticed — long
enough for one of its sentences to become a false statement about where
dependencies travel.
Parity is declared, never inferred. The companion abridges most sections on
purpose: 3.7's 111-line list is nine lines there, and twelve of seventeen
sections differ structurally by choice. A whole-file rule would fight that and
land twelve findings of recorded debt on day one. lockedSpecSections names the
five that are full translations — 3.11 and 3.13 through 3.16, the delegation
group, which is where changes actually land — and adding a section to it commits
every later change to that section to both files. It is the same reason the
host's sensitive paths are declared rather than read out of how a path is
spelled.
The check reads structure and never wording: the heading sequence across both
files, and each locked section's sequence of block kinds. Size is compared only
where a translation cannot legitimately change it — a table row and a fenced
line survive translation, a wrapped sentence does not — so prose line counts are
never compared, English hard-wrapping at 80 columns against unwrapped Chinese
stays quiet, and a test pins that. Comparing prose would fire on every
legitimate translation choice, which is a judgement this tool cannot read from
structure.
It lands at zero recorded debt: the five locked sections are in parity as of the
previous commit, so the rule's budget is zero and any drift fails rather than
being absorbed.
Verified against the drift it was written for. Dropping the 3.13 table row that
actually went missing reports:
docs/SPEC.zh-CN.md:282: [spec-parity] section 3.13 table block 2 has 9 lines
here and 10 in docs/SPEC.md
and exits 1.
A failed item collapsed every non-cancellation error into one status plus a
sentence, so the caller deciding whether to re-issue the graph with the finished
nodes adopted had to read the message. The identity already existed one layer
down and was being discarded at the fleet boundary: provider.RetryableStatus
knows 429 from 400, and APIError.ErrorCode knows an overflow from a rejection.
Confirmed the identity survives the trip before building on it: a
*provider.APIError returned by Stream reaches RunProfileSpec intact, status and
code readable through errors.As. Classification therefore reads what the error
already carries rather than decorating it.
Four classes, each sourced from a real identity — provider.transient (408, 429,
5xx, or an interrupted stream), provider.rejected (any other 4xx),
context.exhausted (ErrCompactionRequired, or a documented context-overflow
code), and unclassified for everything else. Nothing reads message text. An
error whose producer named nothing is reported unclassified rather than guessed
at, and a test pins that an error whose message reads "rate limit exceeded"
stays unclassified: this is the rule that retired the phrase tables, and a
failure surface is not where it gets an exception.
The identity travels to the branch the failure killed, because a skipped item is
worth re-issuing exactly when its cause was.
Skip policy is unchanged. Retrying inside a run is a separate decision and needs
its own evidence; adopt_ref is already the caller-side retry primitive.
Second half, found while testing the first: a skipped branch made runFleet report
the whole call as cancelled and answer context.Canceled. A rate limit is not an
interruption, and that error is what the turn loop reads to tell an interrupted
call from one that ran and reported. Only a real cancellation answers it now —
including the pre-cancelled context the old skipped check happened to cover — and
the aggregate headline gained the third state it was missing, so a run that
reached its end with failures says how many of its tasks were answered instead of
claiming to be either clean or cancelled.
docs/SPEC.zh-CN.md had drifted three commits behind on 3.13 and 3.14: the
upstream payload, adopt_ref with list_subagents, and the measured for_each
exclusion never crossed, and one sentence had become false — dependencies "never
reach ProfileExecSpec" after they had started travelling on
ContextRequest.Upstream. Both files now describe what the kernel does.
The cycle ran a fixed ["auto", "light", "dark"], and "follow the system"
looks exactly like whichever of the two it currently resolves to. On a
light machine the default auto stepped to light: not one pixel moved, so
the control read as broken. The next step now comes from what the system
is rather than from the array's order, and the first click always
repaints.
One hop stays silent -- returning to auto lands on the scheme auto already
shows, and that is what those three states mean. The button answers the
press itself so the click is acknowledged either way.
Every neutral in the palette sat at hue 255-267 while the accent sits at
75: the greys were 185 degrees from the one colour the product owns, which
is what made them read as somebody else's. They are OKLCH now, at the
accent's hue and a chroma low enough to still be grey, with the lightness
carried over untouched from the hex each one replaces -- so every contrast
ratio the comments there argue for still holds.
The four surface steps were declared but only the centre used them, so the
window was one flat plane with hairlines drawn on it. The frame drops to
the canvas and the middle column becomes a sheet on it. Radii go to
1/2/3/4: an instrument is machined, not moulded, which is what lets rules
and columns take over the dividing. Terminal output, delegate panels and
returns, the approval, and the right column's sections all lose their
boxes for rules.
--warn and --accent were the same hex, so "each colour does one job" was
not true of those two: needing you and costing you were indistinguishable.
warn moves to H45 at 8.14:1 dark and 5.83:1 light, matching accent's 8.35
and 5.77.
The mono stack shipped no face, so the layer carrying every label, tag,
figure and terminal line rendered in Cascadia on Windows and SF Mono on a
Mac -- the problem the comment above --ui says was solved, still open one
line below it. IBM Plex Mono Var, 81KB, OFL like the other two. It has no
geometric shapes and no U+2717, which fall through to the shipped Noto, so
they stay identical across platforms but off the monospace grid; the two
places a check and a cross share a marker column use x instead.
Motion: a weight tier now decides duration and easing together, and
choreography has one mechanism -- sibling-index() rather than fifteen
hand-written nth-child rules. The composer row had grown to eight items
against a chain that stopped at seven, so the eighth entered with no delay
at all. Streamed transcript cards are deliberately not staggered: they
arrive one at a time already, and delaying them would delay the work.
Light is emitted by readings, never painted on surfaces: the live symbol
blooms in its own category colour, the gauge leaves a phosphor edge as it
grows, and a finished turn gets one sweep and one flash. A grain overlay
takes the sterility off surfaces that are otherwise perfectly uniform,
which no real material is.
event.go states the contract: a Retrying indicator is transient, and the
next stream event -- or TurnDone -- clears it. The chat TUI does that. The
window only cleared it on a text or reasoning delta, so a turn whose first
packet was a tool call left "retrying 1/5" and its clock standing for the
rest of the turn, over calls that were running fine.
The clearing moves to a rule about event kinds: the kinds that say nothing
about the connection leave the wait standing, and everything else is the
provider having answered.
Two more the same measurement turned up. RetryScope was on the wire and
ignored, so a body-phase replay was announced with the header-phase
sentence -- 1/5 is maxStreamRecoveries, and headers retry ten times. And a
retry between two steps used to show nothing at all, because the indicator
only rendered inside a wait that the first packet had already ended.
The clock now counts from the stamp the wait carries rather than from the
component's mount, so it reports the stall rather than the turn.
The prefix is what prompt caching pays for and one changed byte re-bills all of
it, so the useful question is not how often the cache held but what stopped it.
CompareShape already answers that every turn — system, tools, or the reason a
Rewrite queued — and the verdict rode to the frontend and stopped. This carries
it: cache_miss_reason, one bucket per attributed cause, nothing inferred here.
Rewrite takes an open reason string, so an unknown one buckets as other instead
of letting a caller widen the wire's bucket space.
The complement is the case the kernel cannot see. A prefix that held and still
returned no cached tokens is a gateway that dropped cache_control, an entry that
expired, an endpoint that never cached — downstream, unattributable, and exactly
the shape of the route that billed twelve million prompt tokens at full rate
with nothing anywhere reporting it. It buckets as unexplained, above the
smallest prefix any vendor here will cache so that turns which were never
cacheable stay out of it.
uploadSignals is the silent gate: a counter the sink records but the list omits
is queued and dropped without a word, and locally that is indistinguishable from
a feature that works. A guard now drives a turn through every recording branch
and fails if the wire rejects what came out. It found tool_call_reasoning_recovery
dropped since it shipped — the bucket is a ProtocolRecoveryKind, a closed enum,
never content — and that is now allowed through.
Built, shipped behind the surface, and measured against the call it replaces —
the same graph with one task handling every subject. Three fixtures, twenty-eight
graded runs against a real provider, every run of both arms solved, and mapping
spent 70%, 85% and 98% more tokens for it (exact permutation p <= 0.03 each).
The last fixture was written to be the case mapping should win: ten modules of
near-identical code, a hundred and sixty lines each, and an answer that is the
sum of ten separate derivations so a slip anywhere is a wrong answer. It did not
win there either, and one run solved it by grepping the constants out rather than
reading anything — which is the reason. A mapped child pays a full sub-agent's
fixed cost per subject, while a single child with a tool belt never has to hold
the subjects at all: it reads them one at a time, and when the facts are
extractable it extracts. "One context cannot hold N subjects" assumes an
ingestion an agent does not have to perform.
So the graph vocabulary goes back to id and depends_on, and SPEC 3.14 records the
exclusion as measured rather than as taste.
Two things survive the removal. The edge dedupe in newFleetPlan stays: a task
named twice in one depends_on was already counted twice before for_each existed,
and the item would have waited for a result nothing publishes. So does
unresolvedDepCounts, which adoption needs — an adopted node enters resolved and
its dependents have to be ready on the first pass.
benchmarks/fleet-fanout goes with it. The history holds both if a case that
genuinely needs per-subject isolation ever turns up.
Claude caches only where cache_control marks a breakpoint, and that field is
serialized by internal/provider/anthropic alone. The same model reached through
an openai-kind entry is not an error and not a visible wire difference — it is
full input rate on every prompt token, and the only symptom is a cache read
that never arrives. Measured on a live gateway: 3610 input tokens with no
breakpoint against 7 plus a 3603-token cache read with one.
The judgement reads structure and nothing else — an entry that sets both a
dialect and a model list, resolved through the package-level slice the models
usually live in, because an entry that never spells the name in its own literal
is the ordinary case. Fixtures are exempt: a test builds the broken shape on
purpose to assert what it does.
realyyds_test.go pins the reason a yyds-anthropic entry exists at all, in the
//go:build live form this repo already uses for gateway probes.
The one finding is recorded, not fixed: the vendor's Anthropic route could not
be reached to tell a gateway that lacks one from a preset that picked the wrong
dialect, and asserting either in source would be inventing the fact. The
ratchet is where an open question of that shape belongs, and the rule still
fails every new one.
The counters said how often a turn cached well and never how much it cost.
A flat-rate plan is priced on the tail, so the shape has to survive the wire:
turn_prompt_tokens, turn_output_tokens and turn_cached_tokens are magnitude
buckets taken once per turn, because three 40k requests are one 120k turn and
the plan is paid on the turn. The per-turn scalars move behind turnCounts so
both boundaries reset by whole-struct assignment and the next field added
starts clean.
Surface was hardcoded "cli" at both post sites while stats spelled the same
vocabulary a third way, so internal/surface now owns it and boot, telemetry
and serve read it from there. Or(fallback) makes a caller say what an unset
field could only have meant rather than letting the code guess. One machine's
queue is shared by every surface on it, so the flush groups by surface as well
— without that a window's turns post as the bare server's.
The window and the headless server reported nothing at all: DesktopMetrics and
DesktopTelemetry were settings with no sender. They are separate consents, so
backgroundFlush takes the ping apart from the drain and each is honored alone.
Enabled stays fail-closed, so a development build, CI or DO_NOT_TRACK still
refuses, and a non-interactive server counts only where telemetry was turned
on deliberately.
runServeWithOptions moves to serve_frontend.go, where the serve frontend's
entry point belongs; cli.go was 2595 lines and 1795 over the ceiling, and the
extraction lowers its budget by more than the move costs the file that gains it.
Two fixtures, twenty graded runs against a real provider, and mapping never once
solved something the single-task form did not: 20/20 on both arms. What it cost
was 85% more tokens on the cheap fixture (exact permutation p=0.002) and 98% on
the one written to favour it — ten modules each hiding its effective timeout
behind a three-step derivation, where grepping the constants answers nothing
(p=0.029) — with no wall-clock gain either time, at the default concurrency and
at a ceiling raised past the mapped width.
So the mapped fields leave the provider-visible surface. The schema field and the
sentence describing it are dropped together, so the description never advertises
a parameter the schema does not carry, and a call naming for_each is refused
rather than half-honoured.
There is no setting. A capability the host cannot recommend does not get a knob:
turning it on is a change at the wiring point, to be made once the case that is
still untested is measured — subjects whose combined content one child cannot
hold at all, which neither fixture builds.
The code and its tests stay, and benchmarks/fleet-fanout now holds both pairs.
The evidence for switching it back on and the evidence for deleting it is the
same suite either way.
A capability has no ablation arm — there is no "the same thing with the payload
removed" for for_each the way the dependency edge has one — so the honest
comparison is what this call had to look like before it existed: one task
handling every subject. benchmarks/fleet-fanout holds both, identical except
that the middle item takes for_each rather than depends_on, graded the same.
Against the real provider, n=6 per arm across two concurrency ceilings, both
arms solved 6/6, and mapping a one-file check over twelve subjects spent 85%
more tokens (exact permutation p=0.002) and 47% more money (p=0.026) for no
wall-clock difference (p=0.70). Raising max_subagent_concurrency past the width
did cut the mapped arm's wall time, and cut the single task's by more.
The mechanism is a sub-agent's fixed cost — prefix, reasoning, closing contract,
once per subject — against per-subject work of reading one short file. It is the
same boundary the dependency edge has: both pay in proportion to what a unit of
work costs relative to that overhead, and both fixtures so far measured the cheap
side. So the tool description now says to map only work that needs a run of its
own, and SPEC 3.14 records what the fixture measured and what it did not.
for_each names the item whose submitted subjects this item maps over: its prompt
becomes a template run once per subject, and it reports one bounded aggregate
that its dependents open with over the ordinary dependency edge.
The mapped children are never vertices. The node stays one, so the reachability,
write claims, and skip rules preflight proved are the ones that ran — adding N
vertices mid-run would invalidate the precomputed reachability that
skipDependents and the concurrent-claim check both read.
Four things are fixed before anything starts, and that is what keeps for_each
from being the first keyword of a workflow language: the template, the width
ceiling (max_items, defaulted to 8 and hard-capped at 32), the read-only grant —
which removes the write-claim analysis the host could not have done for an
unknown number of writers — and the source. The source supplies only which
subjects, through submit_items rather than prose, because reading a list out of
an answer is the host guessing at a judgement the structure does not carry. The
caller owns the topology, the worker owns the data: the same split the
dependency edge makes.
submit_items reaches only a source's registry, so a capability nothing in a run
can use never enters its prompt. A source that finishes without submitting fails
the mapped node rather than quietly mapping nothing, while an empty submission is
a real answer that completes it. A source may not be adopted, having never run to
submit anything, nor itself mapped, since it answers with an aggregate rather
than a list.
SPEC 3.14 said the graph vocabulary had no dynamic fan-out. It now says no
computed edges, which is the invariant that actually mattered.
Execute's preflight moved into preflight(), which returns a proven fleetCall,
and the ctx-gated tool attach sits beside the other ctx-keyed host framing in the
two sub-session entries; that is what paid for the new lines without widening the
repolint baseline.
depends_on ordered its endpoints and delivered nothing, so a research →
implement pair paid for the same research twice. Three changes that compose:
- The edge carries the dependency's answer. It travels as
ContextRequest.Upstream, never inside TaskSpec.Objective, because the
objective must stay the pristine text delivery classification judges —
ClassifierTaskText is captured before any host framing. One 8 KiB budget is
shared across a node's dependencies, so a wide fan-in cannot flood the
opening turn and no dependency is starved out of it.
- list_subagents enumerates the children a conversation owns. A reference is
the only address a child answer has, and a background fleet that a restart
repaired to interrupted never delivered the aggregate carrying those
references, leaving its completed children unreachable.
- adopt_ref stands a node down to an already-completed child's answer instead
of running it. It is proven in preflight through ReadFinalAnswer, so what may
be adopted cannot drift from what read_subagent_result may read. Nothing
runs, so the node claims no write_paths and cannot collide with a live
writer; prompt and every execution field are refused on it rather than
silently ignored.
Whether an adopted answer is still valid is not readable from structure, so the
host does not decide it: adoption is addressed by reference, and the caller that
listed the reference judges freshness. That is also why a plan fingerprint does
not quietly reuse matching children — reuse the caller cannot see is reuse it
cannot correct.
A child now inherits something, which is exactly what InheritedContext exists to
keep a decision rather than an accident, so the capsule records it and SPEC 3.13
says so.
--ablate upstream leaves the edge ordering its endpoints while delivering
nothing, which is what lets the payload be measured apart from the order.
Against the real provider on benchmarks/upstream-edge/fleet-edge-wide, n=6 per
arm, removing the payload cost +27.6% tokens (exact permutation p=0.011) and
+59% sub-agent tool calls for the same answer, 6/6 solved either way. On a fact
one grep away it buys nothing: the edge pays in proportion to what the
upstream's work cost against how small its result is.
boot.go's delegation registrations moved to delegation_tools.go and Execute's
spec loop to buildItemSpecs; that, plus folding two defaulting branches into
firstNonEmpty, is what paid for the new lines without widening the repolint
baseline.
The refusal carried "use POST /inbox/items for durable follow-up" as its
detail, and the frontend's wording for that code interpolates the detail — so
what reached the screen was half a Chinese sentence with an API route glued to
it. The kernel was telling the client what to do and the client was showing
that instruction to a person.
Both halves. The refusal keeps its code and drops the route: the English is for
a log now. And the client does what the code asks — it queues the words as a
durable follow-up, which is a row that says it is waiting rather than an error
nobody can act on. That also closes the race behind the report: the turn reads
as finished on screen while the kernel is still landing it, and typing in that
window produced a refusal for timing, not for content.
A queued row now says which wait it is in. Guidance lands at the next tool
boundary; a follow-up goes when the turn does, and the two are not the same
promise.
DetectLanguage reads REASONIX_LANG, then the POSIX locale variables. Windows
sets none of them, so every native surface on a Chinese Windows fell back to
English — the CLI's own words, the folder picker, the status icon's menu —
while the webview beside them read the browser's list and got it right. Two
halves of one app answering the same question differently.
The machine is asked last, after anything set on purpose. It goes through a
variable so the priority between the two is testable on a machine that answers
either way, rather than only on one that happens to be installed in Chinese.
Catalog could not use it: an empty preference means "follow the machine", and
what Catalog returned instead was whatever the process had already installed —
English, for a window that installs nothing. CatalogFor resolves the same way
DetectLanguage does and installs nothing, which is what a shell whose interface
language is a setting of its own actually needs.
Three defects, one feature. The icon drew and then answered nothing, left
button or right: systray creates its window and pumps GetMessage on whichever
goroutine calls Run, and RunWithExternalLoop — which reads like the embedding
path — starts that pump on a goroutine nobody pinned. A Win32 message queue
belongs to a thread, so the window sat on one and the pump read another. It has
its own locked thread now, on Windows; the other platforms keep the documented
path, because macOS puts its status item on the main thread and Wails already
owns that one.
Clicking it did nothing for the commonest case, a window that was open and
merely buried: show and unminimise are both no-ops on that, so the raise has to
be asked for. And the icon read as a brown blob with a black slit, because the
notch was painted in the window's own dark page colour — an assumption about
the taskbar behind it that a light one disproves. It is cut out now.
The switch for it could not be switched: the field took the value and the
renderer never wrote it, so every save dropped it and the setting turned itself
back on. A setting the renderer drops is a setting that does not exist, and the
round trip is now a test.
The settings pane draws the dependency instead of enforcing it invisibly: the
close-to-tray switch hangs off the icon switch, indented, because without an
icon there is nothing to bring a hidden window back and the second switch is
not a choice. The icon itself is a launch preference — systray quits once per
process, so an immediate off would be a switch that cannot be switched back.
[desktop] close_behavior has been normalized, migrated and editable since
before this shell existed, and read by nobody: quit|background was a promise
the app did not keep. This is the half that was missing. The close button hides
where an icon can bring the window back, and quits where it cannot - no icon,
no backgrounding, because a window that vanished with no way back to it would
be worse than either.
What the icon says is folded in internal/traystate, which owns no OS handle and
draws nothing: panes in, one State out, ranked so that being needed outranks
being busy. Nothing on the wire announces an answer to an approval, so the fold
reads the first thing the run produces afterwards as the resolution - a turn
blocked on one produces nothing until it is answered, which is what makes that
sound rather than a guess. Background jobs are pulled on a timer instead,
because a job announces its life in a sentence and matching those words is the
judgement this codebase keeps retiring.
Quitting from the menu runs the window's own close sequence rather than a
second one. The reason that sequence exists - two processes writing one
transcript - does not care which control asked for it.
Windows is verified: it builds, and the icon's own encoder is the 22-byte ICO
header around a PNG. macOS and Linux compile from here but cannot run: this
machine has no CGO toolchain for either, and the thing to check there is
whether systray's external loop is happy beside Wails' own on the main thread.
/config/problem and /config/repair reached the kernel over HTTP and nowhere
else: the window routes by table, so both answered with index.html, and the
banner that says a config file will not parse could never load in Studio. The
dev proxy had the same hole.
The two guards that read the kernel's own registrations are what caught it,
which is the whole reason they read those rather than the client.
Typing while a turn runs queues the line for the next tool boundary, and nothing
could cancel it. The durable item had an id and a delete route, but the delete
refused the one state a queued steer is in, and the frontend had thrown the
receipt away - so the row on screen had no name to cancel by.
The authorization comes from the executor's queue rather than the durable state.
Its lock is the only place that can tell "not read yet" from "already on its way
to the model" without racing the run loop, so the drop there is what permits
removing the durable half: in that order, and not at all if the drop fails. Too
late answers with its own identity instead of a state name, because "removed"
and "already gone" are different sentences to the person waiting.
It rides the verb that already existed, so the CLI's inbox pane, ACP and the bot
inherit it with the controller. Studio grows one control beside the queued badge,
visible without hovering for it.
The settings screen showed built-in defaults while the user's own config sat
unreadable on disk - settings nobody had chosen, presented as theirs - and said
nothing until a save was refused with a parser's sentence about columns. The
runtime already recovers from this by loading the last-known-good snapshot;
loadForEdit does the same now. The save guard is unchanged, because a file
nothing has read is not a file to overwrite.
The refusal carries an identity. A config that will not parse is one condition
wherever it surfaces, so every panel answers config.unparsed with the line, its
text, and the one repair that is certain: a Windows path in a basic string, said
the way TOML accepts. The parser locates the escape it refused and the parser
confirms the result, so nothing here reads the message it wrote and a file it
cannot finish is left alone. The sandbox explains itself by code for the same
reason - the English under a Chinese heading was the kernel talking to a person.
While that path was open: the 24 places in internal/serve answering with a bare
error string now send a code, and refusal-path guards that envelope the way it
already guarded http.Error. A body carrying other fields is a report a panel
renders, and stays out of it.
A background job held the workspace writer lease until it was terminal, and for
a dev server that is never: the next session's first write waited behind
something that was never going to end, told only that it would continue
automatically when it was safe. The retention hook fired for every registered
job, so the case it really covered - a process the user left running - is the
one case it must not.
Agent runs already take the lease for themselves, so nothing needs the hook. It
is gone, with RetainUntil and the jobs option that carried it. A background
subagent still holds the lease for its whole run, because that run is bounded;
a process left behind is not.
The wait it does report is legible now. Contention under a second stays silent -
it is either milliseconds or a whole turn, and reporting the first kind left a
permanent line about a wait nobody experienced. Past that the open is a warning,
because the turn is stopped for the length of it, and it is always closed by a
report carrying the measured wait. Studio holds the state on the run strip while
it lasts and rewrites the card in place when it ends; a headless run sees both
ends on stderr, where it used to see nothing at all.
Remote workspaces are what this version is: a machine reached over SSH whose
folders and conversations sit in the sidebar beside the local ones. The rest
is what that took — a Windows host, a fingerprint someone has to read, a pane
addressing a runtime of its own over there — plus the effort ladder becoming
a fact about the endpoint, which is the one entry that changes what an
existing setup does.
`until_output_matches` and the reworded timeout_seconds description are a
deliberate change to the provider-visible tool surface, so the recorded
baseline moves with them.
Cache impact: the tools hash changes and the prefix hash with it, which
cold-starts the prompt cache once per machine. The system prompt is
untouched, and the schema grows by 91 tokens.
Polling a long job costs a round per look, and the alternative was waiting
blind — so the model kept choosing to poll. wait now takes a pattern and
returns the moment a job writes something matching it: one round for a job
that runs an hour, and still woken by the line that matters.
The pattern comes from the caller, because only the caller knows what it is
waiting for. A host deciding which words deserve an interruption would be the
same guess this codebase keeps retiring, and RE2 makes an untrusted pattern
linear rather than a way to hang the run.
Two things a naive version gets wrong, both found by the tests failing:
a watch registered after the line was written must still match — otherwise
asking a moment too late waits out the whole timeout for something already
true — and one registered mid-line must be seeded from what is already there,
or a pattern the next write completes is never seen.
What a wait reports is a reading, not a verdict: how long the job has run,
everything it has produced, and how much of that arrived while this call was
waiting. Slow progress and a stop differ there, and which one a task should
look like is the caller's to know — not a threshold anybody has to configure.
Two CI failures, both mine. Windows lint: the agent method was offered
unconditionally there, since the pipe name is fixed and nothing read an
environment variable to decide — so the caller's nil check could never be
false. It knocks first now, which is both what the check wanted and one less
dial per handshake on a machine with no agent. Windows tests: three of them
built a JSON body by hand around t.TempDir(), and every backslash in a
Windows path is an escape, so the body never parsed.
And the report behind it: a background job that redirects its output into a
file is silent on its own streams, which the watchdog called "may be stalled"
after fifteen minutes of it downloading a hundred megabytes. Silence is the
fact; stalled was the guess. wait now says how long a job has been running
and whether any of it ever reached this side, so the difference between a
task writing elsewhere and a hung one is visible rather than inferred — and
the answer names the longer timeout instead of another short step.
Two halves of one report from a user, whose screen showed the same notice
twice and then "model finished without a visible final answer 3 times".
The cause: a gateway can answer 200, hold the stream open long enough to look
healthy, and end it having sent nothing — no content, no reasoning, no tool
call, not even a usage record. That reached the turn as an empty answer, so it
spent three retries on it and named the wrong party. Told apart, it is
StreamInterruptUpstreamError like any other failure the far side reports
inside a 200: retried by the request layer, and ending with what happened. A
stream carrying only a usage record is still the model answering, and keeps
the turn's retry — the case that guard exists for.
The screen: repeats fold into one line and a count. Notices carry a code on
the wire that the session state dropped, and with it the ones this build has
wording for read in the reader's language rather than the kernel's English.
A code it does not know still reads.
Classification moved into stream_failure.go, which is what that file is for.
openai.go got shorter for it and the freed budget is reclaimed.
A machine worked on for months holds thousands of conversations. The local
column caps its list at thirty for that reason — drawing them all is what put
98k nodes in a sidebar once — and the remote tree, added later, drew every one
of them. A host can be folded now too, which is what makes several of them a
list rather than a scroll with the local projects somewhere above it.
Two things followed the focused pane that should not have.
The event pump still asked the far hub for /events with no runtime prefix, so
it listened to that hub's default runtime while the pane sent its turns to the
one it had opened. Everything worked and nothing came back.
Appearance was read and written through whichever pane had focus. A remote
kernel keeps its own copy, so switching to a pane on another machine repainted
this window with that machine's theme. It belongs to the window: the local
pane is what these three now read and write.
Windows answers SFTP with /C:/Users/... and its kernel takes C:\Users\... The
first spelling travelled all the way to the far hub, which tried to open
C:\C:\Users\... and refused — reaching the window as a bare 502, because that
one path had no code on it.
The platform converts, since only it knows both. The pane's name is cut the
same way: either separator can appear in a path this machine does not hold,
and its own filepath rules are not the authority on one.
It never was. The launcher linked the frontend in from the source tree, and a
symlink whose destination is outside the bundle fails codesign --strict — so
the app had a signature that verified nothing, and an app macOS cannot verify
gets no stable identity to hang a Local Network grant on. That is the whole
distance between "ping reaches the host" and the window saying no route to it.
Both fixes are the released bundle's own: copy dist rather than link the tree
(scripts/studio-build.sh has always copied), and sign --deep, because
everything under Contents/MacOS counts as code and each file needs its own
signature. The launcher now verifies afterwards and says so if it fails,
rather than leaving that to be discovered as a networking bug.
Three places still told the reader that a remote must be Linux or macOS, the
window's refusal among them. What it should say is narrower and more useful:
the link is fine, that machine's system is what a kernel cannot be installed
onto — and name the three that can.
Everything below the SSH link assumed a POSIX shell. It now goes through one
interface — which shell, which spelling of a path, how a process is started
there and found again — so the difference is in one place instead of a branch
at every call site.
Two things about Windows had to be discovered against a real machine rather
than reasoned about:
Detachment. OpenSSH puts a session's children in a job object and ends them
with the session, so a serve started by Start-Process was gone before its
port file appeared. What the WMI service creates has no such parent, and that
is the setsid of this platform.
Quoting. Commands travel as -EncodedCommand — base64 of UTF-16LE, which holds
no character cmd treats as special. That removes the outer quoting problem
rather than solving it: cmd's rules are where this would have become a
security bug, and a path with an apostrophe in it now proves the point in a
test. Inside the script PowerShell's single quotes follow the POSIX rule.
Also: the CLI release ships Windows as a zip holding reasonix.exe, and the
downloader knew only tar.gz holding reasonix — so a Windows remote had no
install path at all.
Verified end to end against a real Windows host: bootstrap, launch, survive
the session, HTTP through the forward to /status and /tree, then stop.
macOS grants Local Network access only to an app whose Info.plist says what
it wants it for. Neither bundle said anything, so the request was never put
to the user — no prompt, no entry in the privacy list, and every LAN host
answering "no route to host" while ping and the CLI reached it fine.
The release bundle had this too: any host on the user's own network was
unreachable from the window and reachable from everything else.
The launcher also signs with a development certificate where one exists. An
ad-hoc signature's hash changes with every build, so the grant would have to
be given again after each one, which is indistinguishable from it not working.
LocalBinary was copied from the CLI, where the running executable is reasonix
and uploading it is the fast path. Here it is the window: the far side would
receive a Wails app, probe it for a serve command, and reject it — after
paying for the transfer. Left unset, the install falls to npm and then to a
verified release download, which is what it should have done from the start.
Connecting to a Windows host failed as a bare 502 — "the request did not
reach the kernel" — when the SSH link was fine and the far end simply has no
uname. The reason existed the whole way up and was dropped at the last hop:
an error with no code reaches the window as a status and nothing else.
Unsupported remotes now carry a sentinel, so the window can say which half
failed rather than implying the link did. The wording carries no detail on
purpose: what such a machine answers is its own shell's complaint in its own
code page, and putting that on screen explains nothing.
Everything else keeps its text under a coded fallback, which is what makes a
failure legible at all instead of arriving as a number.
Everything above the dial — what the agent offers, which keys IdentitiesOnly
filters out — was inside the !windows build tag, so the Windows half could
not have reused it even when someone wrote it. It moves to a file with no
tag; each platform now supplies only how to reach the agent.
Windows reaches it through the pipe its own OpenSSH service fixes the name
of, with SSH_AUTH_SOCK winning where a port of the Unix agent set one. A
named pipe opens as a file, which is the same call the agent's own clients
make, so this needs nothing new to depend on.
The tests are the first for this code that run on every platform: an agent
key authenticating, IdentitiesOnly offering one key out of two, and an absent
agent not consuming publickey — the last mattering most where the pipe name
is fixed and the method is therefore always registered.
Until now a remote host offered exactly one workspace — whichever the book
named — which made it a shortcut rather than a machine you can work on. A
connected one now answers for itself: its folders and the conversations in
them, read through a pane already open on it, so no second connection and no
second serve process.
That is also why a pane had to address its own runtime over there first. With
one, resuming a remote conversation is the same act as resuming a local one,
and the sidebar can tell which of them this window is already driving.
Unconnected hosts keep the single row, which is also the connect button:
before a kernel is running there is nothing on that machine to ask.
The proxy strips the pane's prefix, so what reached the far hub named no
runtime and landed on its default. Two panes on one workspace share a link
and an address by design — and were sharing the conversation as well: one
transcript, two writers, both streams interleaved.
A pane now opens its own runtime on the far side and addresses it, which is
also what makes resuming a remote session possible at all. It is retired when
the pane closes, before the forward that reaches it goes away, or the far
machine collects runtimes until its own ceiling refuses the next connect.
The kernel builds a structured mismatch — which record it contradicts, down
to the line — and the path to the window flattened it into a sentence. Now
the link layer names what it knows: a changed key, a declined fingerprint and
a refused credential each carry their own code, and the mismatch carries the
known_hosts record so the reader can go look. There is still no way from
there to connecting anyway; a warning you can click past is not one.
The parity guard did not catch the missing wording, because it matched bare
identifiers only and a host outside the package calls the constructor
qualified. It watches both now — verified by removing a wording and seeing it
fail, which is the only way to know a guard is looking at anything.
Until now the link layer had nobody to ask, so it took the strict path: a
machine not already in known_hosts was refused, and a passphrase-locked key
could not be used at all. Both are questions, and the window is the only
thing that can put one to a person — so they travel out on the shell's bus
and the answer comes back through a binding, since the dial is blocked on it.
The fingerprint dialog is deliberately the harder one to get past. Its
fingerprint wraps rather than truncates, because one with its middle elided
cannot be compared to anything, and the focus starts on the way out: Enter is
a reflex, and accepting a key nobody read is what this exists to prevent.
A machine was only addable from the CLI, which made the sidebar section
something the window could show but never fill. The book is user-global, so
an entry belongs to the person and not to whichever folder happened to be
open when it was added.
The listing returns the stored row in full rather than the fields a row
displays: saving replaces an entry, so a page editing one field while holding
a partial copy would blank the passphrase variable somebody set from the CLI.
Forwards have no control here and are carried through for the same reason.
Importing beats typing — on a machine that already uses ssh the addresses are
written down next door, so ~/.ssh/config aliases the book does not have yet
are offered as one-click rows.
Hosts are a section, not a prefix: workspaces on one machine share a
connection, so the state belongs on the group — when a link drops, the whole
section dims together, which is what those rows actually are to each other.
Local workspaces stay unmarked, so carrying a chip is itself the signal. The
same chip appears on the pane tab and in the crumb, because a command lands
on whichever machine the focused tab points at.
A cold connect installs a binary on the far side. The kernel already reports
each step, so the wait is a list of them rather than a spinner that cannot
tell downloading from stuck.
Two function fields become one interface. The split it draws is the one that
matters: the book of hosts is configuration and stays in serve, while what a
link is doing belongs to whoever holds it — so the hub joins them without
learning what SSH is.
The pool records state whether or not a caller subscribed. A window that
opens a second pane an hour later reads the same row as the one that dialled,
and the connect step a first attach is on has somewhere to be read from.
The hub gets the endpoint from a hook the host wires, so the two halves meet
above it: a window supplies a pool that dials, and a listening server leaves
it nil. That default is the point — a kernel that dials onward because a
request asked it to is someone else's way into the network behind it.
A hold the attach took and the hub refused would be a connection nothing can
ever close, so the endpoint gives it back on every path that does not publish
a pane.
Three sweeps reached into a local assembly and would have found none. The
stream needed more than a guard: the asset server holds a response until its
handler returns, so a page inside the window cannot read SSE at all — the
shell reads the far kernel's stream and re-emits it onto the same bus a local
pane's frames ride.
Resuming rides what the stream already carries: the remote numbers its
resumable frames and honours Last-Event-ID, so a link that drops mid-turn
costs only what its replay log has since dropped.
Dialling a configured host lived in the CLI, where a second frontend could
only copy it. It moves to attach, which adds what a window needs and a
terminal did not: a pool where two workspaces on one machine are one login,
and a forward per workspace that the last pane out takes down. The remote
serve is left running — it outlives the link by design.
Exercised against a real SSH server with SFTP and forwarding, so what the
tests cover is the link and not a stand-in for it.
The hub takes an endpoint, not a connection: what makes a pane remote is
where its HTTP goes, so SSH stays above this layer and a proxied pane is
testable over httptest. The frontend addresses /rt/{id}/ either way.
Host decisions reach local panes only — a remote one has no assembly here
to apply them to. The stream is what the proxy has to get right, and the
test withholds the second frame until the first has arrived.
CheckPlanModeReadOnlyTrust had no caller outside its own tests. Everything
behind it was still there: the gate interface and its request type, two setters
and the coordinator that propagated them, the approver on Controller, the
session-trust map in approvalManager, the slot that map occupied in the
authorizations a controller rebuild carries, the boot callback that persisted a
prefix, and two approval-card branches in the TUI. None of it could run.
The bridge was superseded rather than abandoned, and the code says so in three
places: agent's interface ("ordinary Plan execution no longer invokes it; bash
calls use the normal permission gate"), Options ("classifies bash through
Permissions instead"), and config ("Main Plan bash calls now use the ordinary
Permissions classifier and Sandbox"). What was left was the wiring around a
decision already made.
The config field stays. Its comment claims exactly one job — old config and
session round trips — and that job is real: reading a reasonix.toml that still
carries plan_mode_read_only_commands must not fail, and rendering it back must
not lose it. Both are still tested. What is gone is the runtime that field no
longer feeds.
Tests that borrowed the removed tool constant as a sample keep their subject
with an ordinary tool name; the two plan-mode tests keep theirs, which was
never the bridge but what replaced it — bash reaches ordinary permission as the
declared writer it is, and a writer stays behind permissions. Tests of the
bridge itself go with it.
Touches internal/control/approval.go, a declared sensitive path. The change
there is confined to the plan-mode trust map and its slot in
SessionAuthorizations: grantSession, the granted map, requestApproval and
RequiresFreshHumanApprovalTool are untouched, and the rebuild test still proves
an ordinary session grant survives a controller swap. No path gains an
approval, loses a prompt, or widens what may run without one.
Removal was driven by the compiler and then by `unused`, one orphan at a time,
until both were clean. Net -592 lines.
vendorCapabilities declared compactionOutputTokens and two vendors set it, and
nothing read it. Its comment describes a real intent — "the separate budget for
native/summary compaction calls … without inheriting a large default" — and
that intent is already met, one level up and one grain coarser: the fold's
provider call sets MaxTokens from agent's summaryOutputMaxTokens rather than
from the client's answer budget.
The numbers say the same. DeepSeek's entry is DefaultOrdinaryOutputTokens, 16K
— exactly what summaryOutputMaxTokens already applies, so wiring it would have
changed nothing there. The other is 8192, and has never taken effect.
Making it per-vendor is a feature, not this: a compaction call would have to
say so on the request, which provider.Request has no way to carry today. The
coarse limit stays where it works. If the per-vendor grain is wanted later, it
starts from that missing signal rather than from a field nobody reads.
A field that is written and never read is a claim about state that nothing
backs. `unused` does not catch them — a constructor assignment counts as a use
— so a sweep over every unexported field in internal/ turned up the candidates
and each was read before deciding.
transcriptDirty (cli): eleven writes, no reader. Its comments still described
what it did — "forces a viewport re-feed after that in-place rewrite", and one
naming #6978 for what it must never force. #6978 replaced the whole-history
rebuild with invalidateWrapFrom, and setTranscriptBlock calls that on every
in-place rewrite, which is what re-feeds a same-length change. The reader went
then; the flag, the eleven writes and three comments crediting it did not.
recoveryGeneration (agent): a second copy of a generation that already travels.
Its comment says it is captured "so ObserveResult can ignore stale results
after a mode switch" — and ObserveResult does exactly that, from the local
recoveryGen the call site passes it. The copy on toolOutcome went nowhere.
Neither removal can change behaviour: nothing read either one. What changes is
that the comments no longer credit a mechanism to a field that is not part of
it.
c.mimo reads as vendor identity and is not: its one use rewrites tool schemas
out of the pre-2020-12 tuple keywords, which is a fact about the dialect the
endpoint speaks. NormalizeLegacyTupleItemsForDraft202012 says as much — a
provider "must opt in only after the target endpoint's schema dialect is
known" — so the field carries that, not a name.
This came out of looking at whether the client's six vendor booleans should be
one enum, and they should not. They are not one dimension. deepseek, minimax,
zhipu and longcat are thinking protocols and are mutually exclusive, decided by
one switch. This one is a wire-compatibility need, and kimiK3 is a contract
shape; both are resolved independently, and both can be true alongside a
thinking protocol — a base URL at xiaomimimo.com with protocol="deepseek" sets
deepseek and this flag at once, and that is correct: the endpoint wants
DeepSeek's thinking shape and needs its schemas rewritten. An enum would make
that combination unrepresentable and force a product decision — which vendor
wins when the declared protocol and the host disagree — under the cover of a
refactor.
So the scalar count stays where it is. What was actually wrong here was one
field claiming to be an identity.
Job carried five artifact fields and wrote to them from four places, and the
rule for recording a failure was spelled three times in two different ways.
Close kept the first error — "closeErr != nil && j.artifactErr == \"\"" — while
both writes overwrote whatever was there. Once a disk fills every write fails,
so the message that survived was the last one, which says nothing the first did
not. They are one type now, and noteErr is that rule in one place, the way
Close already had it.
The timestamps go the same way: started, activity and finished are the job's
timeline, and activity is the one stall detection reads — a job can run for an
hour with its output stopped in the first minute, which is why it is not
derivable from the other two.
tombstone goes entirely. It was set true in one place, when a finished job is
rebuilt from its persisted metadata, and read nowhere: the state it meant is
already carried by a closed done channel and a terminal status, and Manager
tracks per-session loading separately. A field only ever written is a claim
about who depends on it that nothing backs.
Job goes 18 scalars to 11.
goalMachine's state reaches a rotated session through capture/restore, and
both copy field by field. Adding a field to the machine and forgetting it in
either one compiles: the goal simply arrives without it, and nothing reports
the loss. Twenty-one fields are copied by hand in two directions, which is a
lot of chances to miss one.
Two guards read the declarations and both function bodies. What is left out is
named with its reason — the two locks, the epoch restore bumps rather than
carries, and the budget and state path that belong to the controller that built
the machine rather than to the goal being moved — so leaving something out is a
sentence someone writes, not a line someone forgets.
Checked both ways a field goes missing. Adding one to goalMachine without
carrying it: named by the first guard. Declaring it in the snapshot and
dropping its line from restore: named by the second. Removing one from the
snapshot struct needs no guard — that one the compiler already stops.
This is what the 21-scalar ceiling on goalMachine is really asking about here.
Grouping the fields would satisfy it, but the fields are read in 242 places and
the persisted goalState cannot follow them, so the copies would stay hand-
written and the loss they invite would stay possible.
Each of these sat on Controller and was read in one or two places, all inside
one subsystem: the MCP default call timeout only ever fills in a spec the MCP
manager builds, the implicit-invocation switch is only asked about skills, and
the slash sequence only numbers a slash-invoked skill's synthetic call. They
belong where they are consulted, not on the object that happens to hold both
ends.
skillSet's comment claimed every field is set once at construction, which
slashSeq would have quietly falsified — it now says which field is the counter
and that it synchronises itself.
Controller goes 20 scalars to 17. The remainder is values (the workspace root,
the label, the model ref) rather than flags, and the ceiling is aimed at flags
whose combinations describe states nothing reaches: workspaceRoot alone has 64
readers, and wrapping it to reach a number would cost every one of them a level
of indirection for no state it makes illegal. What Controller actually needs is
the responsibility split the memory and checkpoint managers started, not more
field moves.
The ratchet caught this change trying to bring two-line field comments in and
was right to; they are one line each now.
Controller carried running, finishing, canceling, rotating and closed side by
side. Their own comments say they constrain each other — "running and rotating
are mutually exclusive gates", closed "seals turn admission" over all of them —
which is exactly the shape the scalar ceiling exists to catch: five independent
flags describe 32 combinations, and a controller only ever reaches a handful.
They become turnGate, and the two questions the call sites kept re-deriving
become its methods. `running || finishing` appeared three times and is what a
bare running check gets wrong — the window where TurnDone is still in flight —
so it is active(). The four-way "anything at all in the way" appeared twice, in
two files that had each spelled it out, and is busy().
Nothing moves out from under c.mu: the group is a value field on the same
struct, so every critical section is the one it was. Checked with -race.
Controller goes 25 scalars to 20. The rest do not group this way and should not
be forced to: what is left is mostly construction-time configuration that
belongs to a subsystem rather than to the controller — the MCP call timeout to
the MCP manager, the implicit-skill switch to the skill set, the goal token
budget to the goal machine. Putting them in one bag to reach the ceiling would
read as a group while being a bag.
Agent carried 15 scalar fields against a ceiling of 12. The ceiling exists
because independent flags multiply into states no type records as legal, and
the fix it blocks is adding one more bool — so two groups come out by lifetime,
which is what the rule asks for.
steerInbox is the queue and the two flags around it. They already shared a
mutex and a lifetime — opened on the way into Run, closed on the way out — and
now share a type, so the transitions are its methods instead of seven call
sites reaching for the lock. take() hands the entry back rather than loading
its body under the lock, which is the one behaviour change and the right way
round: no inbox lock is held across a read.
agentRole is what an agent is when it is built and stays: a planner that may
not execute, an executor told to reach for its tools, a caller that needs
visible final text. That fixed lifetime is what separates them from planMode
and the language settings they were sitting next to, which move between turns.
deliveryProfile looks like one of them and is not — beginRunTurn recomputes it
per turn — so it stays where it is.
Agent is at 12, and the reclaim takes the room with it: baseline drops
struct-state for agent.go entirely, along with the file-size and function-size
the two extractions freed. Nothing was raised. The ratchet also caught the new
file trying to carry two essay findings in, which is what it is for.
Reported: at a larger appearance the context-breakdown bubble runs off the
right edge and is clipped, and the smaller the scale the further left it sits.
Both directions are the same mistake. The interface is scaled with CSS zoom,
and the placement mixed the two coordinate systems that creates. Measured in
Chromium at zoom 1.5: a 232px box reports 348 wide, an element at left:400
reports 600, and writing left:300 puts it at 450. So a client rect and
innerWidth are both read on screen — the clamp against them was right — while
the left written back is multiplied by the zoom again on its way in. At 1.5 the
clamped position landed 50% further right, at 0.8 it landed short.
scale right edge, before → after (viewport 1000)
0.8 447 → 512
1.0 640 → 640
1.3 991 → 832
1.5 1266 → 960
Dividing once at the end is the correction the stylesheet already makes for the
same reason, twice: calc(100vh / var(--zoom, 1)), because vh keeps measuring
the unscaled viewport.
The tab context menu placed itself the same way and had the same bug, so both
now go through one placer. Its arithmetic is a pure function so the invariant —
what renders has to be inside the viewport at any scale — is checked without a
browser; the browser half is the measurement in the header, taken with a probe
rather than assumed. Removing the division turns three of the four red.
stripComposePrefixes kept its own copy of the tag list and named five of the
eleven the host injects. So <workspace>, the two language blocks,
capability-route and interrupted-turn-recovery went into the BM25 index as if
the user had typed them: a query for a path matched every turn of every
session, and the search preview rendered the block instead of the message.
The list now comes from the package that injects it. history already imports
agent, so this is the copy going away rather than a new dependency, and the
scan it shares advances through the blocks instead of re-running an ^-anchored
ReplaceAll per block.
TokenizerVersion goes to 2, which is how an extraction change reaches indexes
that already exist — and that bump surfaced a bug of its own. Rebuild fills the
projection through a Catalog built directly on the migrated db, bypassing Open,
so the row kept the schema default of 1; opening the result then saw a stale
tokenizer and wiped what the rebuild had just written. It stamps the version it
built with now. The constant had never moved, so nothing had ever asked.
Verified by removing the stamp: the rebuilt projection comes back empty.
Every save walks the whole transcript to derive the sidecar's preview line and
user-turn count, and each user turn goes through StripTransientUserBlocks. Two
patterns there were quadratic in the turn's own length.
The leading-block pattern is ^-anchored, so a ReplaceAll can only ever take the
first block — and the loop around it re-scanned the whole string once per
block. Advancing past each match reads the turn once and allocates nothing.
The trailing execution-policy cut was `(?s)...*?...\s*$`: a lazy body under a
tail anchor, which backtracks over the string for every start position it
tries. It becomes a byte-exact suffix cut, which is what the delivery-runtime
marker beside it already does — and that one's comment gives the other reason
to prefer it: a lazy pattern anchored at $ swallows user prose between a
literal mention of the tag and the real block at the end.
Measured on one more turn appended to an already-saved session:
messages before after
100 22.8ms 19.0ms
1,000 70.0ms 35.4ms -49%
5,000 196.1ms 119.3ms -39%
20,000 652.3ms 432.6ms -34%
The benchmark stays. What remains is a different problem and not this one:
loadSessionUnlocked is 43% of the rest, because the write check replays the
event log to see whether another writer moved the file — a crash-consistency
mechanism, not an accident.
Reported: a third-party endpoint serving deepseek-v4-flash answered every turn
with "field ReasoningEffort invalid, should be one of: low, medium, high,
xhigh, none". That vocabulary is not DeepSeek's — it has no "medium" and spells
the switch "disabled" — so the endpoint was a relay speaking the OpenAI one,
and the composer had offered "max" because the ladder is keyed by model name.
Pressing continue re-sent the same setting, so the turn could not recover.
The model table already states the rule for the other field it carries:
ContextWindow "is a fact about the model and not about who serves it — a relay
passing it through has the same ceiling". Levels are the opposite kind of fact
and were being inherited the same way. Each measured ladder now names the
VendorHost it was measured against, and only that host is given it. Protocol
and window keep travelling with the model, which is what the table was added
for; the switch between them is host-only, matching isMimoEntry, so a lookalike
hostname cannot claim a vendor's extensions.
Elsewhere the ladder narrows rather than disappearing — a relay with no control
at all is what the model table was added to fix. What is dropped is the levels
outside the API's documented vocabulary ("max", "xhigh"), and they degrade onto
the deepest standard level instead of being refused, the way "minimal" already
degrades. A relay that does take them says so with supported_efforts, which
outranks everything the host would otherwise assume.
The protocol fallback needed the same split: an entry declaring the DeepSeek
protocol without a table entry was offered max wherever it pointed. Narrowing
it unconditionally is what the first attempt did, and TestNormalizeEffortDeepSeek
caught it — that fixture is the vendor host with an unlisted model, which must
keep max.
Three existing expectations move, all of them the behaviour being fixed: a
proxy no longer lists max, a gpt-5.6 relay no longer lists xhigh/max, and the
gpt-5.6 test that asserted a relay takes them "as itself" now expects the
degrade its own comment describes ("an alias degrades rather than sending a
level the model will reject").
Receipt.Write decides what the delivery gates, the baseline, the path
invalidation and the cross-turn diff evidence can see, and it was set from a
list of seven tool names kept in evidence. A writer added without an entry
there keeps working while its writes stop being attributable to a file, and
nothing fails.
ReadOnly could not answer instead: it is false for bash too, which mutates
without naming what it touched. Previewer could not either — it is shaped
around one path and a move has two, which is why move_file never implemented
it. So the question gets its own contract, PathWriter, and the seven tools
answer it themselves.
ReceiptFromToolCall now takes ToolFacts rather than a bare readOnly bool. The
paths that only have a name — fold coverage, the fold index, the cross-turn
PathsProvenInSession — resolve it through the live registry the way
toolIsReadOnly already did for read-only, and that helper is gone since
toolFactsFor answers the wider question. An unresolvable name reads as a read,
so a replay of a tool this build no longer has invents no writes.
Verified the swap before making it: across every built-in, "not read-only and
its arguments carry paths" agrees with the old name table on all thirteen
legal calls, disagreeing only on malformed ones that fail anyway. That is the
evidence the contract covers the same set, not an argument for that rule —
a future tool that runs a path without writing it would break the rule and
still answer PathWriter correctly.
Three guards in builtin: the seven declare it, bash and kill_shell do not, and
nothing read-only does. Checked by flipping write_file's declaration — the
guard names it, and the cross-turn sign-off e2e goes red with it, which is the
behaviour the contract actually feeds.
Also here, from the same sweep: IsDiagnosticSuccess had a command table whose
every branch returned the same value as the line after it, so it decided
nothing; and its doc claimed it kept a success from clearing the failure event,
which the caller does unconditionally two lines up.
Test doubles standing in for writers now say so instead of being recognised by
the name they answer to, and the fold-coverage test reads the shipped registry
rather than its own copy of the answers.
Two things were wrong with the one number watching the largest item in every
first request.
It was at 5700 of a 5700 budget — no room at all, so the next field anyone
adds fails CI with nothing to say about whether that field was worth it. And
it counts the whole built-in set, while a session is billed for the schemas
the provider is shown: 13 of 23, because everything else is reached through
use_capability. Promoting one tool onto that surface costs every session and
moves the guarded number by nothing.
So boot guards the visible surface on its own, at the goal-armed variant
because it is the larger of the two. It fails if the allow-list stops
restricting anything, which is the way this test could otherwise pass while
measuring the wrong set. Checked by lowering it until it went red.
The room comes from the three largest descriptions, each of which ended by
restating its own schema field by field. complete_step's restatement had
already drifted from what it described — it documented `step` while the schema
prefers `step_id` and keeps `step` as the fallback — which is what a second
copy of a contract does. todo_write keeps the two things its schema does not
carry: the two-level shape and the verbatim-step_id rule.
built-in set 5700 -> 5443 budget 5700 -> 5600
visible 3841 -> 3584 new budget 3700
goal absent 3305 -> 3141
Cache impact: 256 tokens leave the provider-visible prefix, so every existing
session cold-starts once and is warm again after. SystemHash is unchanged in
the golden, which is the evidence the base prompt was not touched; ToolsHash
and ToolSchemaTokens (4531 -> 4275) are the tools alone.
The fold effect test came along because it measured this indirectly: it
compared the last request against the run's peak, so a cheaper prefix delayed
the second fold and left more turns after it than before. It now checks each
fold where it happened, which is the invariant it was written for. Verified by
disabling the strip: the counts go linear and it names the fold that kept them.
The batch planner kept a table of six names that never joined a parallel
run. All six return ReadOnly() == true, which is the whole problem: one
bool was answering two unrelated questions. ReadOnly says a call needs no
approval, because it touches no file and starts no process; batching asks
something else entirely, and for complete_step, todo_write, compress, wait
and bash_output the two answers differ.
So the second question becomes its own contract. Each of the five declares
Sequential with the reason it cannot share a batch — a sign-off advances the
task list, a fold rewrites what the batch is reading, a collector reads what
an earlier call in the reply started.
use_capability was in that table because it "may resolve to a real MCP
writer". It now answers for what it proxies: a directory read shares a
batch, a call is its target's catalog entry, and inspect (which can start a
server), decline (which writes the ledger) and an id the catalog cannot
resolve keep their place. Nothing loosens the writer path — an MCP tool
without an explicit readOnlyHint is already false. What this buys is the
case the name table could not express: several read-only capability calls
in one reply now run together instead of one after another.
The four batch tests asserted the fake's contract rather than the shipped
one, which is exactly how a name table survives being replaced by one, so
they take the real registry. Two guards in builtin fail if a tool stops
declaring Sequential, or if an ordinary reader picks it up; both were
checked by breaking the declaration and watching each go red.
Sixty-two commits since 2.3.0: three panels for kernel capabilities that
had no front end (usage, memory editing, single-file revert), the
parallel-call prompt, and the DeepSeek price-table correction.
A change list, not a narrative. What a reader needs from this file is
what changed and whether the upgrade asks anything of them, so the two
that do — the cost figures rising and forking being gone — lead as
breaking changes, and every other entry states the change rather than
the defect behind it. Entries that only a maintainer could act on are
not entries.
2.3.0 is rewritten the same way rather than left as the odd one out; its
published release body is updated to match.
CommitFileRevert had grown to 141 lines and complexity 39, over both
budgets, and the lint gate has been red since. Each stretch it had
accumulated decides one thing, so each becomes a function: claiming the
plan, what the plan alone settles, what the barrier must re-verify, which
preimage the path resolves to, and how the target's payload is staged.
Resolving the preimage was duplicated in PrepareFileRevert and is now
shared.
/usage was registered on the kernel but missing from both path lists the
shell keeps: the window's API whitelist and the dev proxy's. Either one
answers index.html instead of JSON, so the panel read a 404 in the app and
in `pnpm dev` alike. The route parity tests had been red since the endpoint
landed.
A high-effort review of the usage, memory and file-revert work turned up
fifteen findings. Fourteen are fixed here; the two most serious were both mine
and both confirmed before touching anything.
The revert button lied about its scope. store.PrepareFileRevert takes
earliestRevisions(0) — the session's first preimage, not this turn's — so
"put this file back the way it was before this change" promised a surgical undo
and delivered a session-wide one, silently discarding every other edit the
session made to that file. It now says what it does.
Currencies were being added together in the projection. The JSONL path keeps
them apart and three tests prove it; the catalog path, which is what answers
once it is ready, summed 1.50 CNY and 0.25 USD into one column and labelled the
result with whichever currency arrived last. Cost moved to its own table keyed
by currency — tokens add up and currencies do not, so they cannot share a row.
Normalization moved to ingest so both paths agree, and two tests now cover the
catalog path the earlier three never reached.
The rest, in the order a reader meets them:
- keep_current is the kernel's deliberate no-op; the card reported it as
"reverted", the exact opposite of what the user chose.
- A plan the kernel already refused still drew a confirm, and posting it
answered "missing planId" because a refused plan carries none.
- The hero stated the cache hit rate against report.tokens, but the rate
partitions the input side alone. The one number the card exists to teach.
- Usage.tsx had grown its own money/token/percent formatters — the exact
duplication i18n/format.ts documents itself as ending, down to the symbol
glued to toFixed(2) that renders CNY as yen in an English window.
- The daily-spend chart plotted cost[0] and stamped the axis from the first
priced day, merging away the currencies the panel exists to keep apart. One
chart per currency now, for the same reason tokens and money get their own.
- Estimated quotes were aggregated under the label "paid" although the recorder
flags every one of them.
- Three sibling memory handlers answered "memory is disabled" three ways: a
code, a raw English sentence, and a silent empty 200.
- PrepareFileRevert stored plans without the staleness sweep its sibling runs,
and this branch made it reachable from every diff card.
- A SchemaVersion bump renamed the projection file with nothing deleting the
old one, so each bump would orphan another multi-MB database.
- The mock indexed the full arrays with a slice index, so its "7 days" was
neither seven days nor the right seven.
- The plot rebuilt a 365-segment path on every pointermove.
transaction.go went over its budget by seven lines, so single-file revert moved
to its own file — it is a separate responsibility and the sweep is now one
method both prepares call.
Not fixed: /memory/revisions and /memory/restore still have no caller, so the
"an edit is safe because the old wording is reachable" argument is not yet true
from the panel. And control's rewind failures are still bare fmt.Errorf, so the
shapes past canFiles reach the user as an untranslated 500 — the identity rule
REASONIX.md states, owed a separate change.
PrepareFileRevert and CommitFileRevert have been on the Controller with no
endpoint and no caller. The resolution constant says what was missing plainly:
ResolveOverwriteCheckpoint force-writes the preimage "after the user explicitly
confirmed in the single-file UI" — a UI that did not exist.
Two endpoints and a control in the diff header, which is the one place a reader
is already looking at what changed and can see whether they want it back.
Reverting stays two steps because the second one is not always a question. The
prepare answers whether this file is still the one the checkpoint captured; only
when it is not does the reader have to choose between the checkpoint's version
and the current one, and asking up front would ask on every revert. The
conflicted branch is coloured as a decision rather than as another confirm.
Unlike a turn rewind this does not reload the session: one file changes and the
transcript does not, so the pane's callback deliberately skips the reload the
rewind ones do.
Verified as far as this setup reaches: the endpoint contract test confirms both
paths are served, and typecheck, build, i18n parity and the suite all pass. The
click-through itself is not covered — the fixture's transcript only plays after
a real submit, and driving that through the composer's IME-aware key handling
was not worth more time than the feature took.
The panel could list saved facts and forget them. Changing one meant opening
the markdown by hand — while Controller.SaveMemory, MemoryRevisions and
RestoreMemory had been sitting there with no endpoint and no caller.
Unlike the usage panel, nothing was missing from the middle here: the manager
takes a write lock, hands the store the fact, and injects the new text on the
next turn rather than touching the cached prefix — which is the invariant that
makes editing mid-session safe at all.
So this is the two ends. Three endpoints (save, revisions, restore) and an edit
form inside the row that was already expanding to show the body.
The endpoint decides what is editable. Title, description, body, activation and
keywords come from the request; identity, revision and timestamps are read off
the stored fact. Taking those from the panel would let a stale view rewrite an
audit trail it never read.
Saving writes a new revision rather than overwriting, which is what makes
offering an edit safe rather than lossy — the form says so, since a reader has
no other way to know.
Two things the browser found that the source did not: the select had picked up
.pick, a class the workbench already paints with the accent, so it rendered
inside an amber slab; and the parity guard caught memory.unavailable reaching a
frontend that had no wording for it.
The recorder has been appending to ~/.reasonix/stats since it was wired in —
16,321 rows across twelve days on this machine, 4,586 of them carrying a price.
stats/query.go already aggregated it into RangeStats, every field JSON-tagged,
its doc calling it "the full aggregate the settings panel renders". There was
no settings panel, no endpoint, and no caller of Query outside the recorder.
Cost was missing from the middle of that chain. Records carry cost_amount and
cost_currency; usage_rollups had no cost column and RangeStats had no cost
field, so the money stopped at the JSONL. Both now carry it, as fixed-point
integers rather than floats.
Currencies stay apart. Cost is a list with one entry per billing currency: a
single total would have to invent an exchange rate, and the rate a turn was
billed at is not the rate today. A day with tokens and no cost reports none
rather than zero — the field started being persisted later, and rendering those
days as free understates the bill. The panel says so where it shows.
SchemaVersion now names the projection file, which is what makes adding the
columns a version bump instead of a migration: the rollups are replayable from
the JSONL, so the old file is retired rather than altered. That constant had
been sitting unused beside a hardcoded "v1.sqlite".
The panel is one series per chart, so no legend and no colour spent on identity
— length already carries the value. Tokens and money get separate plots because
their units do not share an axis. The one chart colour is the theme's --net
snapped into the readable lightness band for dark mode, which is where it
failed the contrast check.
TurnControl carried eight Submit variants. Four of them are the same two
internal calls with an argument dropped — Submit is SubmitDisplay without a
display, SubmitHTTP is SubmitHTTPFormat without a format — and no frontend
opens any of the four. Submit has 52 callers, all of them tests inside this
package, reaching it as *Controller rather than through the port.
So the port carries the four that mean distinct things and the rest stay on the
concrete type, where their one real user already was.
Removing them takes a trap with it. SubmitUserTurn read (input, display) while
SubmitDisplay beside it reads (display, input); both are two strings, so a
swapped call compiles and runs and shows the wrong text. Its only two callers
pass the same value twice, which is why no test ever noticed. It now reads
display first like every other one.
The port is a description of what frontends drive. Eight ways to start a turn
described the inside of this package instead.
BeginDestroySession opens the window and Finish closes it; jobs pairs them
itself and never consults IsDestroying to do so. The Controller wrapper and its
port entry existed for a caller that never arrived — no frontend, no test, and
nothing inside control either.
jobs.IsDestroying stays: its own tests use it to prove the window opens and
closes, which is the one thing worth asserting about a window.
Counted while auditing the port: 43 of the driving port's 186 methods have no
frontend consumer at all, and they cluster — memory writes (5), single-file
revert (5), most of TurnControl's submit variants. Those are capabilities the
kernel has and Studio has no entry for, which is a product question rather than
dead code, so only this one — provably unreachable from anywhere — is removed.
Auditing the orphans the old desktop left behind turned up a worse kind than a
method nobody calls: a method whose doc says who calls it, wrongly.
ReplayPendingPromptsTo said "Serve uses this for a newly attached SSE client".
Serve uses ReplayPendingPromptsWith, which hands the connection over while the
prompt lock is held; the ...To variant has had no caller on either side of the
port. WriteAuthorityGeneration said "Tests use it to prove old generations
become stale after rebind" — no test does. RebindSessionWriteAuthority offered
itself as a convenience for lease keepers, and no keeper took it.
A doc that names a user is the first thing a reader trusts, and each of these
sent this audit down a false trail before the call graph corrected it. Deleting
them costs nothing that was reachable and removes three wrong answers to "who
depends on this".
The remaining orphans are catalogued rather than deleted: some are a retired
frontend's capability with no replacement (memory doc editing has no serve
endpoint at all), which is a product call and not a cleanup.
Retiring the old desktop took SnapshotForShutdown's only caller with it. The
TUI had never used it: every exit — a quit gesture, SIGHUP from a dropped SSH
session, SIGTERM from a service stop — funnels through tuiShutdownMsg, and it
took a plain Snapshot.
The difference is what happens when another instance holds this session's file
lock. The plain snapshot returns ErrSessionFileLockHeld and stops; the shutdown
variant parks the in-memory transcript on a recovery branch first. Everything
the session added past the last autosave was riding on that distinction, and
the result was assigned to _, so a lock-contended exit lost the transcript and
said nothing.
The error now rides out on the model and is printed once the alt-screen is
gone, which is the only moment it can be read.
The path moved to its own file on the way: the case clause is a call, the
handler and its report live beside the test that reads them. That test reads
the syntax rather than driving the model — Update renders a status line before
it reaches the message, so a stub would have to implement most of the port to
reach one branch. It fails if the handler takes any other snapshot, or assigns
the result to _; restoring both is how it was checked to be watching something.
The five launch-web declarations become two so this lands without widening a
budget.
port.go has always said it — "leaner frontends (bot, acp) depend on just the
sub-ports they use" — and named the bot never seeing checkpoint or memory as
the example of what that buys. Nothing enforced it. The bot named the full
SessionAPI, twelve sub-ports and 187 methods, and calls four of them: eight
sub-ports and 122 methods were reachable by accident, memory and checkpoint
among them. ACP named the full port and drives seven.
GatewayAPI is the four a chat gateway drives; EditorAPI the seven an editor
drives over ACP. serve names one sub-port it never calls and the TUI names none
it does not, so both keep SessionAPI — which is now what its own comment claims
it is.
The guard reads both sides out of the syntax rather than a list someone has to
remember to update: sub-ports and their compositions from this package, the
port types named and the port methods called from each frontend's AST. A
frontend handed more than one sub-port it never calls fails, one being the room
a migration legitimately sits in. Restoring the bot's SessionAPI names the
eight exactly, which is how the guard was checked to be watching something.
The method count in the file header goes with it. It said ~99 against a surface
now past 240, and a number stated in a comment only ever goes stale.
DeepSeek's published rates had moved and this table had not followed. v4-pro's
output was carried at 6 CNY per million tokens against a list price of 13.5
off-peak and 27 at peak, so every cost readout understated by between 2.25x
and 4.5x — for as long as nobody happened to read the pricing page.
The rates are corrected, and the peak schedule they come in pairs with is
applied where it belongs. PeakWindow carries the vendor's own clock: 9-12 and
14-18 are Beijing hours, and a fixed +8 offset states that exactly without
costing an embedded tzdata. The all-weekend rule starting 2026-08-23 is a date
on that same clock. Only a rate confirmed as the vendor's own is rescheduled;
a price a user negotiated is their own arrangement, and projecting someone
else's peak hours onto it would invent a number nobody published.
Which is what exposed the second half. resolveCatalogIdentity decided the
vendor by reading names — strings.Contains(name, "deepseek") — while the
catalogue beside it states the actual test: host equality, because a relay
bills on its own terms even when it serves the same model. Both directions
were wrong. A relay named after a vendor was quoted against that vendor's
table, peak window and all; a vendor's own endpoint under a plainer name was
not quoted against it at all. The host test already existed and config already
used it in ten places — it now reaches the quote through QuoteContext, and the
guessing is retired. An unnamed vendor gets no official table, which leaves
the user's own rate card: right rather than plausible.
An effect test pins it through the real Build stack. Both runs name the entry
after the vendor, because that name is precisely what must not decide it; the
host is the only variable between them. Restoring the old guess turns the
relay case red, which is how the test was found to be watching nothing on its
first draft.
Nothing serves these prices over an API, so CheckedOn dates each row and a
test fails when one goes ninety days unread. It cannot stop someone bumping
the date without opening the page; what it buys is that the question gets
asked at all. LongCat's rows are a launch discount with no published end and
say so.
Peak pricing makes any quote time-sensitive: a test using official rates
without pinning a clock now fails on weekday mornings. QuoteContext.Now and
QuoteInput.OccurredAt are the injection points, and the boot-side tests use
them.
Wiring the host test in cost one line, which put boot.go one line over its
file and function budgets. The CostQuote assembly moved to its own file
instead: boot.go is 25 lines shorter and build 24.
The opening screen asks for a service address and a key, then infers the rest
— protocol, model list, whether it reads images. It never said where the key
itself comes from, and a person who does not have one has nowhere to go from
that field.
Each shortcut now carries the vendor's console, reachable from beside the key
input and again from the refusals that are settled there rather than here. A
vendor whose key page we cannot name links to its platform root instead:
sending someone to a 404 is worse than sending them to a front door.
The refusals had to become codes first. Probing failed as one sentence, so a
refused key, a path the endpoint does not serve and an embedding-only gateway
all read as the same dead end. The status the model-list request came back
with was already typed, and thrown away one frame up; it now travels as one of
nine provider.probe.* codes, each with its own status and its own next move.
Spelled as a switch rather than built from the reason, because the parity
guard reads those call sites and cannot check a concatenated code.
Two defects surfaced on the way. sse_provider threw a bare Error, so a coded
refusal could not have been read even once it existed — post0 already carries
it. And i18n.test.ts excluded the i18n directory, which is where kernel.ts
words every refusal: 37 codes had been reaching English windows in Chinese
with nothing to catch them. The catalogue now guards its own wording, those 37
are translated, and they move to en_kernel.ts — they belong to no screen, and
en.ts was over its line ceiling.
The executor has always run independent calls from one reply in parallel, up
to eight at a time. Nothing said so, and the model reached for one tool per
reply: measured over nine tasks, 71 calls arrived across 65 replies.
Two runs with the sentence, against one without, same nine tasks, all passing
in every run:
replies 65 → 55, 56 -14.6%
calls 71 → 60, 56 -18.3%
wall 244s → 159, 176 -31.4%
prompt 488k → 430k, 398k -15.3%
cost -9.5%
Fewer replies is where the rest of it comes from: a reply is a round trip, and
a round trip re-sends the whole prompt. The sentence costs 66 tokens once, in
the cached prefix.
Cache impact: the prefix gains those 66 tokens, so every existing session
cold-starts once against the provider's prompt cache and is warm again after.
The policy list is now one slice rather than two, since the test that strips
these back off was reading a copy of it.
A measured run: 3,995 of the first turn's 5,577 prompt tokens were built-in
tool schemas. That is the largest single item in a cold request and the thing
a warm one pays to keep cached — and nothing was watching it. A tool gains a
field, a description gains a sentence, and the floor under every session rises
with no one the wiser.
The whole built-in set rather than what a preset exposes, so the number does
not move when an allow-list is edited, and the failure names the largest
schemas so the next reader knows where the weight is.
Both draw one item of a list in the extension page, both own the calls that
change it, and one of them already had a file. The state table only this row
reads goes with it.
Adding an MCP server and adding a plugin package each have a file. Adding a
model source did not — it sat inside the list that shows them, along with the
form for editing one, and the two of them were most of that file's 754 lines.
They move out, each with the helpers only it was calling: the name-collision
check with the add form, the header and extra-body parsing with the edit form.
What is left is the list itself, at 306.
The fixture had split five subjects out; the real side had none, and both
files plus the contract were sitting one line under the ceiling. Taking the
same five across, then four more on both at once — external services, hooks,
network, themes — leaves the two sides matching face for face, and every one
of them with room again: 799 to 517, 778 to 485, 784 to 275.
Each face carries the state that belongs to it. The fixture's server list
lives with the calls that switch a server off, its hook list with the dry run,
because nothing else was ever reading them — which is what made these the
subjects worth splitting rather than a line drawn to hit a number.
Half of the port's types already lived by subject — providers, plugins,
storage, appearance, boundary — and the other half sat in the contract file
with the interface, 784 lines of them, one line under the ceiling. The split
was not a rule anyone was following; it was where someone had last needed the
room.
So the rest follow: sessions, external services, workspaces, skills, models,
account, versions, hooks, network, shell, memory. port.ts keeps the interface
and stays the way in — everything is re-exported from it, so no reader of a
port has to know where a type is written down — and drops to 275 lines.
Each of those names now matches a face on both implementations, so a subject's
contract, its wire calls and its fixture can be read side by side.
The fixture reads as five subjects, each in its own file and chained on so one
declaration still satisfies AgentPort — appearance, extensions, shell,
boundary, providers. The side that actually talks to the kernel had none of
that: one class held every method, and its file sat at 799 of the 800 it is
allowed, as did the fixture's own remainder and the contract beside them. The
next endpoint had nowhere to go.
So the real side takes the same five faces, in the same order, so the two can
be read against each other: sse_look, sse_ext, sse_shell, sse_boundary,
sse_provider, and the port class chained on the end. Adding a provider call
now touches a 59-line file rather than an 800-line one.
Two things the faces share move out with them: rootQuery builds a URL, which
is what the transport file is for, and WailsBind describes what the desktop
shell binds onto the window, which is neither the transport's business nor any
one face's.
The wire's fields already have a contract test; the paths carrying them did
not. Both sides write them as string literals, so the compiler sees one thing,
tsc sees another, and the two are only ever compared by a request that 404s.
One direction only: a route with no caller is not a fault — the CLI and the
setup page reach some of them — while a call with no route always is. The
sweep verified there were none; this is what keeps that true. It fails if
either side stops stating its paths where the patterns can read them, because
a run that compared nothing looks exactly like a clean one.
Giving the extension page somewhere to report a refused switch put Settings
over the 800-line ceiling. The row that draws one skill — with the note about
how the model can reach it, and the scope table only it reads — is a whole
thing on its own, so it goes into a file of its own rather than the budget
moving for it.
Killing the kernel mid-session and pressing Send showed three things at once.
The transcript kept the message — the client adds that row itself, because
nothing on the wire echoes what was typed, and nothing took it back when the
post failed. The composer had already been emptied, so what was typed was
gone. And the notice read "/submit: 500", which is a path and a number.
So the row now carries an id its sender knows, and a refusal takes it back;
the line goes back into the composer, refs and all, since it is the assembled
text that was sent; and a failure that carried neither a code nor a body says
what kind of failure it was instead of printing the message meant for logs.
HttpError records whether the answer had anything a reader could use, rather
than the display end trying to recognise its own fallback string.
Both files this touched were sitting one line under the 800 ceiling, so the
session's types and HttpError move into files of their own rather than the
budget moving for them.
Failing one endpoint on purpose showed what a refusal looks like from the
outside: the switch snaps back — the row re-reads the server rather than
assuming its own optimism — and nothing else happens. No message, and the
error goes out as an unhandled rejection. From the user's side that is
indistinguishable from a click that missed, so they click again.
The model page already had the answer, one place on the page to say why a
switch was refused, with every operation there routed through it. The
extension page now has the same, and the three provider operations that kept
their own try/finally report into it. Versions has no page-level notice, so it
carries one beside the notice it already shows for an unreachable catalogue.
Two sentences there were also being rendered as bare strings; a stale pin and
an unreachable catalogue are exactly the states an English interface would
have shown Chinese in.
Escape already handed focus back to the button that opened the menu. Taking a
value did not — it unmounted the row the caret was on, so focus fell to the
document and the next Tab restarted at the top of the page. Cancelling cost a
keyboard user nothing and choosing cost them their place.
The slotted view's handle closes its menu by hiding it, which drops focus the
same way; it takes the same route back. That one has no reachable path in the
fixture, so it is corrected by the rule rather than by measurement — its label
was also being built as a bare string rather than through the catalogue.
Every screen it walked was a settled one, so the text a failure puts up was
never read. A turn that ends in an error renders two more things — the kernel's
own account of it and the label the run strip settles on — and the second of
those was going out untranslated: `t(doing)` takes its key from a variable, so
the static guard cannot see it, and 已中断 was the one value of eight that had
no entry.
The step needs a key the endpoint will reject to reach that half, and says so
rather than passing silently when the turn ends any other way.
The token table already says this — the base is the fill, the ink is the
reading value — but the sweep found fourteen places still reading the fill:
the slash palette's match highlight and its hints, the approval header's
tool name, the run strip while a turn waits, the rule counters. On a tint of
their own hue they landed between 3.29 and 4.42.
The same walk found ghost carrying text onto surfaces it was never measured
against. Its floor is stated for --raised; on a selected row, a menu head or
a delegation tint it fell to 3.98–4.13, so those sites take the step above it.
warn has an ink of its own now rather than borrowing accent's by coincidence.
Three remain and are not touched here: white on accent, at 4.497 against a
4.5 floor, on the primary buttons. The table records that trade already, and
closing it means moving the base hue.
At 900px the plugin and service rows broke: the name shrank to zero width and
wrapped one character per line onto its neighbour, while the two segments that
refuse to shrink pushed the row's buttons past the window. Shrinking is now
ordered — the supplementary halves give way, the name holds a floor and
ellipses — and the buttons keep their width because they have to be clickable.
Two more the same walk turned up. The breadcrumb separators were named .sep,
which is also the 1px hairline divider, so "/" and "·" were each rendered
into a 1px box with a background behind them. And the role band's second
column was measured against Chinese: "Subagents" overruns it, so that one row
of the four sat out of line. Subgrid hands the width to the band, where a
column shared by four rows belongs.
An ellipsis says there is more; with no title there is nowhere to read it.
The sweep found nine such places in one pass — every skill's description, the
value column of the settings table of contents, session titles, memory
descriptions, a package's name and what it brought. The row they sit in
already puts a title on its scope column, so the habit was there, just not
applied to the parts that get cut first.
The rename field had no accessible name either, and three sentences never
reached the catalogue.
The two existing sweeps answer one question each and only walk the settings
sections. This one walks the workbench too — pickers, the slash palette, the
file reference, a whole turn replaying with its tool cards — and judges what
the render resolves to: contrast against the surface text actually lands on,
clipped text with no title behind it, ink wider than the box nobody clips,
elements past the viewport edge, controls with no accessible name.
The fixture was the only way to reach a transcript with cards and approvals
in it, and it could not be reached: every other face of it answers with data,
but the probe threw, so the demo sat on its connect card with no way past.
tokens.css sets the floor at AA 4.5:1 for the weakest text on its own surface.
Walked over eleven settings sections in both themes, five combinations in light
were below it. Dark was clean throughout.
Two causes. --ghost was computed against --raised (#FFFFFF, 4.55:1 — no
headroom) but renders on --surface (#FAFBFD), where it fell to 4.40. And
--accent served as both a fill with white text on it and as text on a 13% tint
of itself; at 4.55:1 on white neither direction had room, so white on it came
to 4.42 and the badges to 3.3–3.8.
--accent moves to #A7690C so white text on it clears 4.5, --ghost to #677589,
and a hue used as text on a tint of itself now has an ink of its own
(--accent-ink, --ok-ink, --err-ink). In dark the tint is darker than the hue,
so there the ink is the hue.
tools/contrast-sweep.mjs is the walk. It carries two lessons in its header: a
probe that fails to evaluate must throw rather than return an empty list, which
reads exactly like a clean sweep — this one did, silently, for three runs — and
getComputedStyle reports color-mix results as color(srgb …) with 0-1 channels,
which parsed as 8-bit turns a pale tint into a mid grey and invents failures
that are not there.
Terminal output, diffs and inline code all render through --mono, and all three
carry Chinese: a test failure message, a comment in a hunk, a commit subject.
None of the monospaced faces in that stack has a Han glyph, so the character
fell through to whatever the platform chose — on Windows typically a serif,
which at 11.5px is the worst of both.
Alignment does not change. Measured at 11.5px, a Han glyph is 11.5px against a
6.92px Latin cell — a ratio of 1.662 — and it is the same 1.662 whether the
glyph comes from the shipped face, PingFang, or the platform's own fallback.
This was never a 2:1 grid, so naming the face breaks nothing and only decides
what was previously left to chance.
Reading Studio on Windows meant Segoe UI and Microsoft YaHei, and neither
carries a 500 or a 600. CSS then resolves --w-reg (500) down to 400 and
--w-med (600) up to 700, so three weights collapse into two: body text thins
out and a secondary heading renders identically to an emphasised one. The
comment above those tokens explains why Chinese starts at medium — dense
strokes blur earlier than Latin at the same size — and on Windows that
compensation was never applied.
Measured before changing anything, as ink coverage of one Chinese line at
[400,500,600,700]:
PingFang SC 500 625 676 676 a real Medium
Heiti SC 416 416 545 545 500 renders as 400
Hiragino Sans GB 456 456 745 745 500 renders as 400
Both faces are now shipped and variable, so every step exists everywhere and
the design has one answer rather than one per OS. Inter for Latin (343KB), Noto
Sans SC for Chinese, subset to GB2312 plus the interface's own characters —
1.6MB instead of 14MB, with anything outside it still falling back through the
stack. Both are OFL 1.1 and their licences sit beside them.
Static scanning cannot answer this. A constant table holding Chinese is correct
when its render site calls t(), the definition and the render can be files
apart, and `t(variable)` hides its key from every check there is — the contrast
descriptions reached the screen that way, already inside t(), with no entry in
the catalogue. Scanning literals reported 355 candidates, most of them fine.
Walking the real interface in English reported 11, all real:
onboarding provider names and the connect button
model the relay/thinking notes and " · 缺 key"
hooks the recipe titles behind aria-label
appearance the four contrast descriptions
Fixed, plus the 37 keys the widened guard found: t() arguments are now read
through their whole argument list, so the arms of `t(cond ? "A" : "B")` count
as keys. They were written correctly and simply never checked.
One Chinese string is left on purpose — the language picker's own "中文", the
same reason its sibling reads "English".
tools/i18n-sweep.mjs is the walk itself, kept because the next drift needs the
same answer and static analysis will not give it.
The catalogue was only guarded in one direction: every t("…") key had to exist
in EN. Nothing checked the other way — that text which reaches the screen went
through t() at all — so Chinese written straight into JSX rendered as Chinese
in an English window and no test saw it.
The Chinese-as-key design stays. It is deliberate and the reasons hold: naming
thousands of fragments costs more than it returns, the call site reads as the
sentence it renders, and a missing translation degrades to the original rather
than to a blank. What was missing is the symmetric half of its guard.
The new check reads the two places text always reaches the screen — JSX text
nodes and rendered attributes — and requires them to be empty of raw Chinese.
It needs no ratchet: the 31 sites it found are fixed here, so it starts at zero
and stays there.
Sentences split by JSX were the reason some of them were written that way:
`这段做过的 <b>{n}</b> 处改动` is three nodes, and translating the pieces
separately cannot work because English puts the number elsewhere. tx() keeps
such a sentence one key and substitutes nodes into its placeholders, so the
bold stays and the sentence is still translatable.
en.ts already carried "新会话" → "New session", but App.tsx wrote the literal.
On an English interface the tab therefore read 新会话 while the tree row two
inches away read New session — the same word, one screen, two languages.
Found by driving the built frontend headless, where the locale is English and
the mismatch is visible; in a Chinese interface both sides render identically
and nothing looks wrong.
Profile declared {name, description} in TypeScript while this package sent
{model, effort}. Nothing failed — the reads were simply undefined forever, and
the card fell through to a fallback that reported a delegate's step count as a
number of delegates. Type checking cannot see across the JSON boundary, so the
drift was invisible until someone read both files.
The test compares same-named structs field by field in the direction that can
break: a field the frontend declares must be one the wire carries. Extra fields
on the Go side are fine, since a reader ignores them. It skips when the desktop
sources are absent and fails if the two type sets stop overlapping by name,
which is how a rename would otherwise make it compare nothing.
Same situation as the session catalog: nothing read it. Its only importer was
the CLI command that rebuilt it, and no product path ever opened the file that
command wrote. Task snapshots and event logs were already the authoritative
data and are read directly.
That leaves two projections, both with real readers and both doing something a
directory scan cannot: history-search maintains an inverted index for BM25,
usage-catalog a precomputed rollup.
Selecting an effort on mimo-v2.5-pro was refused with "xiaomimimo declares no
reasoning-effort levels", and on older builds it surfaced as a 500. The
vocabulary existed — mimoEffortCapability names auto|none|low|medium|high — but
only the branch for a hand-written reasoning_protocol consulted it. Inferring
the protocol never recognised MiMo, so a stock provider block fell through to
the "no levels" answer and the effort control was dead.
The two switches that named one protocol's levels are now one function both
paths read, and protocol inference recognises MiMo. Declaring the protocol and
having it inferred can no longer disagree, which is what the defect was.
Measured against api.xiaomimimo.com before changing anything: none, low, medium
and high return 200; max and xhigh return 400 "Invalid request parameters". The
levels offered are exactly that set, so the composer stops showing max for this
model and the host refuses it without spending a request.
Nothing read it. Open, ReconcileDirectory, ListSessions and GetSession had zero
callers outside the package: the sidebar, the CLI picker, the bot and doctor all
list sessions by scanning the directory, which answers from sidecars and never
decodes a transcript. The only entry points were `sessions reindex` and
`doctor sessions`, which rebuilt and reported on a file no one then opened.
Measured before removing: scanning 186 sessions costs 17ms, and the sidebar
reads one workspace directory at a time — on this machine 461 of them averaging
a couple of sessions each, so well under a millisecond each.
What stays is what a scan cannot do. history-search needs an inverted index for
BM25; usage-catalog needs a precomputed rollup. Both have real readers. A
projection earns its place when the authoritative data cannot answer directly
and quickly — listing a directory can, because Turns and Preview already sit in
the sidecar next to each file.
The cost of keeping it was not hypothetical: both sidebar bugs fixed this week
were the projection misreading data that was itself correct. 4400 lines, three
schema migrations and a reconcile loop, for rows nothing displayed.
The memory index added yesterday to replace it goes too — it was written for a
consumer that turned out not to exist. Its comparison harness is in the history
if a projection is ever warranted again.
The sidebar folds a conversation's conflict copies into one row by walking
ParentID up to the transcript they came from. GC reclaims covered copies, and
those sit in the middle of the chain — so each reclaim broke the walk in two
and added a row. A long enough conflict loop then showed as a staircase of
same-titled sessions with descending turn counts, which is the report.
A copy now records the conversation it ultimately came from when it is written,
so grouping no longer depends on which of its ancestors still exist. Walking
parents remains the fallback for copies written before this.
Reproduced first: an intact six-copy chain drew two rows, and removing one
middle link drew three.
The catalog keeps a sqlite projection of data whose authority is the jsonl
transcripts beside it, and every bug fixed here this week was the projection
misreading them rather than the data being wrong. This adds the alternative —
scan the sidecars, answer from a slice — next to it, plus the test that only
lets it stand if it answers identically: same order, same page breaks, same
cursors, across scope, directory, query and time filters.
Measured on this machine's real tree (461 workspace directories, the shape a
working install actually has — many directories of a few sessions, not one
large one):
build catalog=543ms mem=32ms
rebuild catalog=32ms mem=35ms (catalog skips unchanged dirs;
mem rescans everything)
query all catalog=768us mem=333us
query one catalog=434us mem=73us
Nothing reads the memory index yet. Writing the comparison first also caught
that the seeded timestamps were being overwritten by SaveBranchMeta, which had
been quietly making every time-filter assertion vacuous.
Forking a conversation at an earlier turn into a second session file existed in
three places — `/branch <turn>` in the TUI and the slash handler, the Fork entry
in the rewind picker, and POST /fork — and produced the one thing sessions
should not do on their own: a second conversation with the same title. It is
gone, along with ParseBranchTarget, the three Controller entry points, the port
methods, and fork_turn / fork_message_index in branch metadata, which nothing
ever read back.
`/branch [name]` still branches from the current tip, which is a branch the
user asks for by name. parent_id stays: recovery GC reads it to find the
transcript a conflict copy came from, so it belongs to the recovery lineage,
not to forking.
A save conflict forks the transcript into a recovery branch, and two writers on
one file produce one per save. Each is a valid session file with the same title
and one fewer turn, so the sidebar filled with a staircase of conversations
nobody started while the file the user was actually in sat at the top.
The list now leaves recovered branches out. They stay indexed and on disk —
GC, diagnostics and the serve-side reader still find them by path — they are
simply not offered as sessions to open.
The lineage pass goes with them: it read the content of every recovery file on
every directory scan to sort them into covered/diverged/canonical groups, and
nothing outside the package ever read the result. Three columns, an index, a
243-line classifier and a per-scan pass over transcripts, all to label rows
that are no longer shown.
The continuation demanded "finish it now" while the completion guard rejects
the one action that phrase describes: a todo_write marking an item done is
refused until a complete_step signs it off. So the model flipped a status, the
guard refused, the list stayed exactly as it was, and the next round repeated
the identical demand. Asking the run to stop changed nothing — the loop reopens
on every user turn — and the stop button was the only way out.
Both the requirement and the continuation now name the three things the guard
lets through: complete_step to close an item (it advances the list, so no
todo_write is needed), a todo_write without an item that should no longer be
done, and conclude_blocked for one that cannot be done as specified.
The stall test also moves off the category list, which stays identical while
the counts inside it change, onto the full requirement state; and a ceiling
ends a run whose gap keeps changing shape without ever shrinking, which no
stall counter can see.
The nested rows under a dispatch are the sub-agent's own calls. The card read
their number as a number of sub-agents, so one delegate doing 64 things
announced "64 个子代理" — while the panel beside it said none had been
dispatched at all, because it matched the tool name "task" and the model only
ever calls use_capability. The wire made the first inevitable: the kernel sends
{model, effort} and the frontend declared {name, description}, so the profile
name was undefined on every card and the fallback always won.
The type now matches what the kernel sends, the label reads nested rows as
steps, and a batch says both numbers. The panel keys off the profile the kernel
sets and sums the contexts opened, so one fleet call counts as its whole batch.
Both readings live in one module: how a delegation is recognised, counted and
named is a single question with two callers.
Every dispatcher is hidden behind use_capability, so the tool name on a
dispatch is the proxy's. The profile that says who ran was resolved only for
directly-called tools, and emitResolvedToolDispatch never carried one — so
every sub-agent the model actually spawned reached a frontend anonymous, with
no way to attribute a step or count the contexts opened.
Profile now describes the delegation rather than just its model: Name says who
runs, Count says how many. A task without a model override is still a
delegation and says so; fleet and parallel_tasks report the size of the batch,
which is the number nobody could previously see. The resolution behind the
proxy reads the real target with the real inner arguments, so a proxied
dispatch and a direct one carry the same identity.
All of it sits in delegation_capability.go beside the alias contract: what a
dispatcher answers to and what it reports are one subject.
Measured over five repeats of the committed no-solution corpus, false
completion ranged 25–50% and honest 42–67% with nothing changed between runs.
A rate printed without its denominator's resolution invites exactly the
comparison that spread makes meaningless, so each line now states the
percentage-point move a single task carries.
The mixed-shape gate below already accepts a check whose status the host reads
out of PIPESTATUS; the declared-check gate refused the same shape. A run that
declares `verifies` and pipes its suite into tail — to keep 200 lines of output
out of its context — is doing what the declaration is for, and the host reads
that stage's status rather than the pipeline's.
Shapes no probe can answer for stay blocked: a `;` hands the status on outside
any pipeline, and nothing there proves what the check exited with.
Cache-impact, Cache-guard, System-prompt-review and Documentation-impact were
enforced by reading text out of the pull request description. Both workflows,
their checkers and the template fields go.
What they were protecting stays: scripts/cache-guard.sh is a test run, not a
body field, and remains the release-level cache-hit check. CONTRIBUTING still
asks that a cache-sensitive change say what it does to the provider-visible
prefix — as prose in review, not as a parsed line.
The proxy description promised `task:subagent`, resolveCall accepted it, and
list/inspect denied it existed — two id tables for one capability. A model that
verifies a capability before dispatching was told the harness had no subagents,
so it ran the work inline and the isolation was lost with nothing failing.
Aliases now belong to the tool that answers to them: CapabilityAliased rides the
contract into Entry.Aliases, Lookup accepts them, and the six hand-written
prefix branches plus taskToolName are gone — one table, three readers. inspect
also returns a registry tool's input schema, which the model previously had to
guess. The web:/lsp:/session:/memory:/workflow: passthroughs had no users, no
catalog entries and no tests, so they are removed rather than documented.
The boot effect test walks CapabilityIDExamples through a real assembly, so the
description can no longer name an id discovery refuses.
Both wizard tests had been failing since deepseek-v4-flash-vision-exp
joined the default preset. Neither found a bug: withBuiltinFamilies dedupes
by name, and a builtin the user has never named is an addition rather than
a duplicate — which is the whole point of that commit, since images fail
without a model that reads them.
So the expectations were wrong, but bumping 2 to 3 would only date them
again. Each now says what it meant.
groupByFamily's invariant is that the whole preset collapses into one
family in order, so the member list derives from the preset. A floor guard
keeps it from passing vacuously on an empty one.
The duplicate check counts names instead of members: the user's two
entries must each survive exactly once, and no name may appear twice.
Removing the dedupe now reports "deepseek-flash appears 2 times; the
user's entry was duplicated" rather than an arithmetic mismatch.
Every goal turn carried the same 1255-byte task contract, unchanged. The
fold now collapses the copies, but between two folds they still accrue one
per turn, and repeated identical prose loses salience while pushing real
content out of the window.
Only the operative half has to be on every turn: pursue the goal, do not
stop at a plan, end by calling update_goal. The judgement rules — scope,
pause policy, completion criteria — are what the model consults when
deciding, and one copy in view is enough. 1255 bytes becomes 442, about
235 tokens a turn.
That only holds while a copy really is in view, and the honest way to know
is to look. There is no latch: the condition is read off the transcript
through SeesStandingBlock. A latch would have to guess, and it would guess
wrong on a fold, a rewind, or a resumed session — none of which tell the
controller anything. It would also guess wrong on ordering, because the
fold runs after Compose has already chosen what this turn says.
The full statement renders as its own variant, <active-goal
contract="full">, so the fold supersedes reminders against reminders and a
reminder can never displace the contract it points at.
The invariant is the test: no request may carry a reminder without a
contract. Breaking any of the three parts fails it with the symptom that
part causes —
strip every retained copy req 5 reminds of a contract it cannot see
one variant for both forms every turn restated the full contract
never restate req 2 reminds of a contract it cannot see
The fixture sets the goal after two ordinary turns on purpose. A goal set
on turn one lands in the pinned first user turn, which no fold can reach,
and the test proves nothing — it passed against every broken variant above
until the fixture matched how the command is actually used.
The eleven assertions that matched "<active-goal>" now match either form.
They always meant "the block is there"; pinning one variant was incidental.
keepUserTurns holds the user's own words verbatim because a constraint
stated mid-session is unrecoverable once a digest drops it. It was costing
each turn at its full size, injected host boilerplate included — so a
40-byte constraint carrying a 1250-byte goal contract spent eight times
its own weight, and the budget meant to protect the user's words was being
spent on the host's. Turns got dropped to make room for duplication.
The copies were also immortal. Retention is verbatim, so every stale copy
rode through every later fold. Counting <workspace> blocks at the provider
boundary across eight turns:
before 1 2 3 4 [fold] 5 6 7 [fold] 8 never falls
after 1 2 3 4 [fold] 2 3 4 [fold] 3 falls at each fold
TransientUserBlockTags already gave these blocks an identity; it was only
ever used to strip them for previews. This splits that list by what the
block means. Standing state — the goal, the languages, the workspace — is
superseded by a newer copy. A one-time fact is not: dropping a memory
write, a finished job, a hook's output, or the policy that governed one
particular turn destroys the only record the model has of it.
Superseded means superseded, so the newest copy of each variant survives.
An earlier revision stripped every retained copy on the theory that the
live turn always restates it, and the representative fixture caught what
that costs: the fold runs after Compose, so the turn whose request is
built after the fold is left with a reminder and nothing to point at. A
block is superseded only by a newer one carrying the same tag AND the same
attributes.
The strip runs inside the fold, which already rewrites and has already
paid for the cache miss. Doing it per turn instead would change bytes the
provider has already seen and cost a miss on every single turn — which is
why the blocks are baked into the stored message in the first place.
We had a lot of compaction machinery and no way for the model to know it
was about to be compacted. Grepping the tree for any figure ever shown to
it returned nothing: the model was always the folded party, never an
informed one. A model that knows it is at 15% writes down the exact path
and the next step before the summary takes them; one that does not gets
folded mid-thought.
Two halves, because they answer different moments.
The push is a tagged fragment appended before the next sampling call, at
75% and again at 92% of the distance to the compaction trigger — the fold
is the event it can still act ahead of, so the figure counts down to that
rather than to the physical window. It rides the turn tail, so the prefix
stays byte-stable; it is edge-triggered, because a notice that re-fired
every step would spend the very window it reports on. The rungs re-arm
when the history is rebuilt.
It hangs in the run loop rather than in control.Compose. A goal turn runs
dozens of tool calls between user turns, and a notice that only fires on a
user turn would never reach the turn that needs it.
The pull is context_budget, for the decision that arrives between the two
rungs: a broad search or a large file the model cannot afford to read.
Measured at the boundary rather than estimated — ToolSchemaTokens in the
golden moves 4362 -> 4509, so the schema costs 147 tokens of prefix, and
SystemHash is unchanged, which is the evidence the base prompt was not
touched.
ContextGeneration lands here because the latch needs it. Compaction
installs a projection and never calls Session.Rewrite, so a latch keyed on
the rewrite counter alone never notices a fold.
Extracting toolCallContext is not drive-by: the one binding line pushed
prepareToolExecution past the 120-line limit, and the repo does not widen
a baseline to land a change. The extraction reclaims budget instead.
Thirty commits since 2.2.0. The lead is DeepSeek's vision model and the
per-turn cost of a long session; the warning at the top is the one thing a
Windows user has to act on, because the fix for it cannot fix the build
they are upgrading from.
DeepSeek shipped deepseek-v4-flash-vision-exp. Three places said the host
was text-only — config's CanConfigureVision, and a defence-in-depth guard
at each of the two provider boundaries — and all three said it about the
endpoint. One endpoint now serves both kinds, so the veto is per model.
Measured against the live API rather than inferred from the docs, which
say less than the endpoint does:
openai surface, image 200, "the image is entirely a solid red"
anthropic surface, image 200, so the default install's wire works
tools 200, so it can be a main model
reasoning_effort low..max 200, reasoning_content throughout
detail=original 200
deepseek-v4-flash, image 400 "This model does not support image"
That last line is why this is per model and not a lifted guard. The ladder
is flash's, because the endpoint answers this model exactly as it answers
flash — same vocabulary, same rejections. The docs never said so; a probe
did, and the entry is dated. detail=original now reaches DeepSeek and is
still dropped for OpenAI, which has no such variant.
An installed user's model list is frozen in their config, so none of that
would have reached anyone. ensureProviderModels returns on a curated list,
which every existing install has. The catalog backfill takes the bound the
Kimi migration takes — touch the entry still carrying exactly what we
shipped — and it ticks vision, because the one model here that reads images
is worse listed and unticked than absent. CanUpgradeDeepSeekProviderProtocol
allow-lists what it shipped, so the third model had to join that list or the
backfill would have stranded exactly the installs it reached.
The panel answered vision per connection while the truth is per model, which
would have greyed the toggle on the one row that works: providerView carries
visionSettable now and the editor reads it per row. The editor also reports
what the probe already knows and the stored list does not — models the
endpoint serves that this connection never listed — so the next vendor
addition is not another code change.
The attachment notice claimed a delegated read unconditionally. With no
vision role set the picture is dropped before the request, and a user told
otherwise goes on to ask what it showed; it now names a model that could
read it, or says plainly that nothing can.
Not done: agent.vision_model stays unset. Pointing it somewhere is spending
someone's money on an experimental model they did not choose, and the roles
panel already asks for the assignment.
internal/config/deepseek_catalog.go takes DeepSeek's official catalog out of
config.go and load.go, both far past the ceiling; the tree ends 46 lines of
file-size debt lighter than it started.
modelVisibleMessages runs every turn and returns the projection plus the
handful of messages appended since it was built — four, on the fixture the
scaling benchmark uses. It got there by copying the whole canonical slice:
/100 21.9µs 76,885 B/op
/20000 2318.1µs 14,085,232 B/op
Perfectly linear in history the model never sees, which is the one thing
folding exists to stop paying for. scaling_bench_test.go already said so —
"the number that has to stay flat" — but a Benchmark asserts nothing, so
the contract was written down and unenforced.
The validity judgement never needed the slice. It needs how long the
transcript is and the hash of the prefix the projection claims, and that
hash was already memoised on (rewriteVersion, n) — someone fixed that half
and stopped. projectionCoversTail is that judgement over scalars, and both
paths make it: the full scan hands it a fresh hash, the turn path hands it
the memo's. Two answers to one question is a bug waiting for the state
where they disagree, so there is still only one.
/100 0.99µs 3,851 B/op
/20000 0.45µs 3,848 B/op
Flat, and 3660× less garbage per turn on a long session. PreparedRequestSize
falls with it, 2334.9µs to 3.3µs, because assembling a prompt was mostly
this. A fold or a rewrite moves the memo; that one turn pays the full pass
and refills it.
Guardian asked ContextMaintenanceSnapshot twice a review for one uint64,
and that snapshot copies the transcript and estimates tokens over it twice
to report what the fold saved. It reads ProjectionVersion now. The snapshot
itself keeps its full scan: CanonicalTokens is the unfolded size, so there
it is the answer, not overhead.
Provider-visible bytes are unchanged, so the prompt cache is untouched:
TestFastPathNeverDisagreesWithFullScan enumerates the states — appended,
rewritten, another model's lineage, hashless sidecar, covered count past
the end — and fails if the turn path ever answers differently from the
scan, or answers at all where it should decline.
TestTurnCostDoesNotTrackTranscriptLength fails at the old numbers.
Three panels, one shape of mistake: the element that answers "which one
is it" was the element the layout sacrificed first.
The / and @ menu carried keyboard selection on a 6px dot and a 10.5px
label, while hover got the full-row fill — the weaker semantic drawn with
the stronger signal. A pointer parked over the list therefore lit a
different row than the one Enter would take, and lit it harder. The
selected row now takes an accent fill and the left rail this stylesheet
already uses for a chosen row, and the keys hold the highlight until the
mouse actually moves. Not --accent-wash: it is mixed against --page and
lands darker than --float, so on a dark theme it would read as a hole.
The connection editor listed every model an endpoint reported, one DOM
row each, unsearchable and unordered. A gateway answers with 216 names
differing by a date suffix (#9192), which made the panel 3914px tall with
the enabled model somewhere inside it and the save button four screens
down. One field now filters and — when nothing carries the name — adds it,
because two boxes would be two controls for one intent. Enabled first,
re-ordered only when the list changes, and the row cap says what it left
out. The same component serves the add-a-source flow, which had the same
list behind chips.
The MCP row in the metrics rail put the endpoint's own error sentence into
.job .rt, a flex:none slot meant for a duration. The only shrinkable thing
beside it was the server name, so the name went to 0px and the rail gained
451px of horizontal overflow that pushed every other block out of line. It
reads like the settings page's .srv now — name on one line, reason clamped
to two below it, failure marked with the same left err bar — and it no
longer borrows a <button> into styles written for a <div>, which is where
the native outset border came from.
perf/pick.mjs, perf/models.mjs and perf/side.mjs measure all three against
the real app; each fails against the code it replaces. The fixture gained
a gateway-scale catalogue and a real-length MCP error, because neither
defect is reachable at the sizes it held before.
isCorruptionError read SQLITE_CORRUPT and SQLITE_NOTADB off the result code and
then searched the message for four phrases. Three of them — malformed, file is
not a database, not a database — are what those codes already say. The fourth
was this package's own sentence: PRAGMA integrity_check answers with a string
rather than an error, so that verdict cannot arrive as a code and was being
recognised by the words the open path had just written.
ErrIntegrityCheckFailed carries it now. The test that covered this built the
error from a string, which meant it was testing the sniffing rather than the
path; it builds it the way the open path does. Two more assert that the dropped
phrases are covered by the result codes and that a message merely quoting the
words is not the check having failed.
Both places searched the message for "context canceled" to tell the user
stopping from something breaking. A wrapped error still contains those words
until someone rewords a layer, and Go already answers the question:
errors.Is(err, context.Canceled). The identity survives the trip because
TurnDone carries the error itself rather than its text, which the render test
now depends on.
It also could not tell a stop from a timeout — DeadlineExceeded does not carry
those words and was reported, while a differently phrased cancellation was
swallowed. turnFailureWorthShowing says which is which and is tested on both.
That judgement moved out of chat_tui.go, which was one line under its size
budget and would have gone over for an import. Extracting it left the file
smaller than before and gave the decision a name.
CompactionDeclineReason cut the reason back out of the error at the sentinel's
own wording, so rewording errCheckpointRejected would have returned the whole
error where a reason was expected. The reason travels on the error now, and the
test proves it by renaming the sentinel and still getting the reason back.
isCardLimitError searched the message for 11310 and 11325 while
isReplyFallbackError, in the same file, already read feishuAPIError.code
through errors.As. Reading them structurally would have silently disabled the
card fallback: the typed error was only built on the reply path, and the send
path returned a formatted string, so errors.As would have found nothing and the
oversized-card retry would have stopped happening with no error and no test to
notice. The send path now returns the same type — its rendering is unchanged,
"feishu send error: ..." either way — and the codes are read off the field.
That path had no tests. It has two, one of them pinning that a send error is
not mistaken for a recalled reply now that both carry the same type and only op
separates them.
The last twenty-seven sites take existing codes where one fits — missingField,
badBody, the editing_disabled family, session.bad_path — and eight new ones
where nothing did. One hundred and seventy-two http.Error calls have become
about thirty-five codes, all of them with wording the panel can say.
writeErr keeps the one plain-text path, because it is what lets code below the
boundary adopt a Reason without a flag day. Its file is exempt by path rather
than by name: failure.go, fail_extra.go and sub/fail.go are all still flagged,
so the exemption stays one adapter and does not become a habit.
refusal-path is baselined at zero. A new http.Error in internal/serve now fails
CI with nothing to carry it, which is what the rule was added for.
The auth and boundary transport refusals, the plugin and theme lookups, the two
storage gates and the wallpaper upload reach the panel as codes. Where a family
already had a convention it was followed rather than replaced:
provider.editing_disabled has four call sites and wording, so permissions,
sandbox, roles and storage take the same shape instead of a generic
editing.disabled that would leave two ways to say one thing.
notFound answers 404, and this batch folded an unknown role and an unresolvable
model reference into it — a 400 in both cases, caught by roles_test. That is
the second time the same helper took a 400 with it, so its doc now says which
failure it is for and names both accidents. A name that is invalid in this
request is not a thing that is missing.
themes.go took notFound(w, "asset", name) in a function with no name in scope;
the compiler refused it. Every batch in this migration has had a substitution
that read correctly and meant something else.
Three "must be one of" refusals become request.bad_value carrying the allowed
set, because naming a field and not what it accepts is a refusal a reader
cannot act on. Two turn-in-flight conflicts become busy.session_running.
The five session-path checks stay five codes. A bad name, sessions being off, a
path that will not resolve, a path outside the directory and the session that
is currently open are a 400, a 400, a 400, a 403 and a 409 — folding them onto
one code is the mistake the last batch already made once, where "unknown
project" became a 404 and the suite said otherwise. session.disabled is reused
rather than reinvented: the frontend already says it, and a second code for the
same refusal is a vocabulary growing duplicate branches.
http.Error(w, err.Error(), status) discarded whatever the error knew and wrote
the caller's status. writeErr renders a coded error as its Reason and falls
back to the old shape for everything else, so the same forty-five sites now
carry a code the moment the code below them grows one — and four session
conflicts collapse onto busy.session_in_use.
It was not the no-op substitution it looked like. providerEntryFrom builds
refusal(422, "provider.name_invalid", ...) and four siblings: the producer had
chosen both a code and a status, and the handler was throwing both away and
writing 400. Honouring one and discarding the other is half a migration, so
POST /providers now answers 422 for those five. The panel is unaffected — it
branches on the code — but it is a wire change.
TestSaveProviderRejectsWhatItCannotStore asserted the status. It now asserts
the code, which is what a client actually branches on and what the migration
exists to deliver; pinning the status pinned the thing that should be free to
be corrected.
The 172 http.Error calls were not 172 distinct failures. "bad body" appeared
ten times, "invalid body" six, "bad request" eight — one kind of failure
phrased twelve ways, none of them translatable, and each one reaching the panel
as a path and a status. Fifty-seven sites collapse onto request.bad_body,
request.missing_field, request.not_found and project.unknown, and four decode
helpers that each wrote their own sentence now share one.
project.unknown is separate because the tests said so. Folding the catalog's
"unknown project" into notFound turned a 400 into a 404, and
TestCapabilitySwitchRefusesAnUnknownProject caught it: a project that is not
open in this window is a request that cannot be served, not a thing that is
missing. A bulk substitution does not read semantics; the suite does.
Moving the codes into constants made the parity check blind to all four — it
read string literals at the call site and nothing else, so a vocabulary that
went into constants left the catalogue unchecked and the test went on passing.
It now resolves a code named by a package constant, and reports the three that
had no wording the moment it could see them.
"Never widen the baseline to land a change" was documented and unenforced, and
-update never told tightening from loosening: it rewrote the file from the tree
and both directions passed silently. Lowering a budget is the ratchet working;
raising one carries debt forward and is the diff a reviewer has to be shown on
purpose. -update now refuses to raise one without -allow-widen, and names the
file, the rule and the numbers rather than reporting that the baseline grew.
The other half is that budgets only came down when someone ran -update, and
people run it when they are adding debt — so the ratchet tightened and loosened
in the same commits and never in between. Today's update dropped file-size by
1447 units and function-size by 855: that was room a file could have grown back
into with CI green. A clean run now reports the surplus so it can be reclaimed.
The first attempt at this ate the report(over) call that prints the offending
lines, leaving a failure that named a budget and no code. Caught by ineffassign
on the now-unused variable.
Boot brings appearance, themes and repair across on an ordinary install, but a
run whose roots come from the environment refuses to — it asked for its own
copies, and moving the production install into it is the bug that rule exists
to stop. Those users were left with a wallpaper that is simply gone and no way
to know why.
The panel now names the directories and where they still are. The historical
list moves next to StateRootEntries: what the root owns and what it failed to
own are two facts about one table and belong in one place, and the recovery and
the notice now read the same one.
The i18n parity check caught the two new strings with no English, which is the
gate working on its author.
Adding appearance, themes and repair to the state root's owned entries only
fixes the next move. An install already relocated has them sitting in the
previous root, so the wallpaper stays missing and the update rollback backups
stay unreachable until someone moves them by hand.
Boot now brings those three across, under the rule the legacy importers already
follow: a run that redirected its roots by environment asked for its own copies
and does not get the production install moved into it. Relocation is a config
table and is the user's standing choice, so that is the case this serves.
Nothing else is touched — sessions and the rest were always owned, and copying
them across would resurrect history deleted since. An entry the new root
already has is left alone for the same reason.
The first version of the central test set the roots by environment, which is
exactly what the guard refuses, so it skipped and proved nothing. It now
relocates through a written [storage] table, the way an install does.
The state root lists what it owns because on a default Windows install it
shares a folder with home, so a move must take its own entries and nothing
else. Three directories written under it were never added to that list:
appearance, themes and repair. A relocation moved sessions, archive, stats and
projects and left the rest behind — and since relocation lands on the next
launch, that is a wallpaper and a theme pack the config still names and the
files gone, which is what a user reported as the wallpaper not persisting.
The repair entry is the one that matters most: those are the backups an update
rolls back to.
The list is hand-kept and the next directory would go missing the same way, so
a test now walks the tree for filepath.Join on the state root and fails on a
name the list does not carry. Removing appearance from the list fails it by
name, at the file that writes there.
REASONIX.md banned reading wording but never required carrying identity, so the
producer side was left to discipline and the same defect landed seven times in
one week: a build step that swallowed its diagnostics, an elevation failure
readable only as a raw errno, a stream stall classified by the word "stalled",
a launch phase read off a message prefix, a cross-volume move matched against
English Windows text, a plugin migration gated on a phrase, and a client that
discarded what the server explained. The rule now states both halves.
refusal-path fails a new http.Error in internal/serve. error-text fails a new
match against an error's rendered text, following it one hop into a local:
the direct form is already extinct in this tree and the 21 surviving sites all
store the text first, so a rule that only caught the direct form would have
reported clean forever.
Both are pass/fail and weigh one. The first draft of refusal-path did not set
Weight, counted 207 violations at zero and reported clean — a gate that looks
like it runs and stops nothing, which is the defect it was written to catch.
The baseline records the 207 and the 21 as debt so new ones fail. It also
tightens five existing ceilings and drops entries for files that no longer
offend: the tree had improved since the last snapshot and -update recorded
what is actually there.
kernel.ts exports `codes` "for the parity check" and nothing imported it, so a
code added on one side and not the other degraded silently to English. The
check reads the codes from the syntax rather than by scanning for them: a regex
looking for codes would be the same defect the coded refusal exists to end, and
the first one I wrote reported codes that do not exist.
It found three on its first run, all in the panel a user had just reported a
failure from: bad_context_window, bad_reasoning_protocol and extra_body_null
carried a code with no wording, so a Chinese reader got the English.
The transport parsed every error body as JSON and, when that failed, threw the
body away and reported "<path>: <status>". Only refuse() sends JSON; the other
172 failure sites in serve use http.Error, which writes the reason as plain
text — so the panel showed "/providers/edit: 500" while the server had said
exactly what went wrong. Its own comment already promised the fallback it never
made: "only when it does not do we fall back to text".
Reading the body once as text and parsing that fixes every endpoint at once,
including the ones the migration to coded refusals has not reached.
The prefix is 5.25k tokens, 4.36k of it tool schemas, and the one per-project
string in it was the workspace path — which sat 23% in, so everything behind it
missed the provider's cache on any project the machine had not already warmed.
Measured against DeepSeek: a directory that had never run reached 256 of 5254
cached tokens. With the path riding the per-turn block instead, the same first
request reaches 5120 of 5262. Over the three-task e2e suite, cache hit goes 76%
to 98% and cost 0.0027 to 0.0008 USD at an unchanged 3/3 pass.
It travels the way role settings already do, in a transient user block that
previews, titles and the rewind picker strip; the tag joins the one list they
are all generated from. The path is filesystem text placed in a turn, so it
stays quoted and the escaping test moved with it.
The goldens are regenerated: system_prompt.txt loses the line and nothing else,
ToolsHash is unchanged. TestEffectPrefixCarriesNoProjectText now asserts what
the goldens cannot — that two projects produce the same prefix — and
TestEffectTurnCarriesThisProjectsWorkspace keeps the guarantee the old
system-prompt assertion was protecting, at the provider boundary.
Cache-impact: high - the prefix is now project-independent; this is the change.
Cache-guard: TestEffectPrefixCarriesNoProjectText plus the regenerated goldens.
Whether a managed plugin's manifest is rewritten on disk was decided by
searching ParseDir's error for "missing apiVersion". That error can be any
parse failure, and a strict decode names the offending field — so a manifest
carrying a field called "missing apiVersion" was sent down the migration path,
failed there for an unrelated reason, and reported "automatic managed-plugin
migration failed" while the real defect went unmentioned.
ErrMissingAPIVersion carries the same words, so no message changes, but the
three sites that decided on them now ask errors.Is. The test drives the real
LoadInstalled path: with the phrase check restored it fails with the warning
the user would have been given instead of the truth.
ClassifyStreamInterrupt matched phrases. Some were ours — "stalled", "no data
for" — so an idle timeout survived only as long as nobody reworded the message
that described it; one was Windows' "forcibly closed", which is rendered in the
system language and matches on an English install only.
An idle timeout is not in a transport error's identity at all. Only the read
loop that set the deadline knows one happened, which is why anthropic and
responses already attach the reason at the emit site. openai did not, so its
stall reached the classifier as an unexpected EOF and came back correctly only
because "stalled" was checked first. Both of its cuts now say what they are,
streamFailure stops relabelling an error that already carries a reason, and the
classifier reads errors.Is alone.
The classifier had no tests. The one that matters most reverts the openai emit
site and watches the reason fall to premature_eof, which is what a reworded
message would have done silently.
readStream is over the function-size budget, so the two cuts are named in
stream_failure.go — the file whose subject is how a body-phase failure is
classified — rather than inlined at their returns.
The button fired ToggleMaximiseWindow without awaiting it and then asked
IsWindowMaximised in the same breath. Two separate bindings racing, and on
Windows the toggle only posts SW_MAXIMIZE to the window for the system to
act on later, so the answer was reliably the state from before the click.
The glyph sat one step behind the window, which reads as the two icons
being swapped.
Awaiting the toggle would not have fixed it — the binding returning is not
the system finishing — and it would have left the other half untouched: a
double-click on the bar, a snap and the keyboard all change the state, and
none of them ran this handler at all.
The window owns the state, so the state is read back rather than inferred.
The click only toggles now, and every path that changes the window reaches
the glyph through the same observer. That observer is the one the layout
already rides on: viewport.ts watches document.body this way, which is the
evidence it fires in this shell.
bash classified a launch failure as the session-temp step by looking for
"session temporary" in the message it had just written itself. A sentinel
says the same thing without depending on the wording.
sessiontemp.ErrUnavailable was the obvious candidate and is the wrong one:
Acquire wraps it only for a nil or closed manager, and returns the
filesystem errors from creating the generation bare, so matching on it
would drop exactly the real failures the text was catching. The sentinel
belongs to the caller that knows which step it wrapped.
It lives in its own file because bash and grep both wrap with it and
neither owns it — and bash.go was already at the 800-line ceiling.
isCrossDeviceMove matched four English phrases against the message inside
the LinkError, having already reached the structured error to get there.
Windows renders that message in the system language, so on a non-English
install none of the four match, the fallback that copies across filesystems
never runs, and the move fails outright. The English text happens to carry
"different disk", which is why it went unnoticed.
The code is what the OS actually returns, so the check reads that instead,
split by platform because the constants are not interchangeable: Windows
answers ERROR_NOT_SAME_DEVICE, and syscall.EXDEV is a synthetic value there
that a real rename never produces.
The existing fallback test faked the failure with errors.New("invalid
cross-device link") — it was asserting on the phrase table — and now
carries the platform's own errno. The new test pairs the right code with a
message in another language, which is the case that was broken.
The watermark every transport restates each 15s is how a client notices a
frame lost at the end of a turn: seq ahead of what it holds means it missed
something. But `seen` started at 0, and a live-only subscription replays
nothing before it — Subscribe() is SubscribeFrom(0), which skips the log
entirely — so every fresh attach to a runtime that had already numbered
frames read the first watermark as a loss of the whole backlog. It replayed
the entire log into the reducer, and the transcript followed it to the
bottom about fifteen seconds after the page came up.
0 was carrying two meanings and the comparison only holds for one of them.
seen is now number | null: the first watermark states where this subscriber
attached instead of accusing it of falling behind. The branches below
already required seen to be truthy, so nothing else changes.
Seeding the baseline from the server at subscribe time was the other option
and is worse: an SSE resume pushes replayed frames whose seq is below the
baseline, which the backwards-numbering branch reads as a restarted stream
and answers with a full rebuild.
hdiutil create ran under -quiet, which suppresses its diagnostics along
with its progress, and the script runs under set -e. A failure therefore
killed the build between the "==> hdiutil" line and a bare exit code, with
the fifteen seconds of stderr that named the cause discarded and the
build_dmg check that would have said something never reached. One release
build already failed this way and could only be diagnosed by re-running it.
FetchIndex fell back to a package constant naming the desktop line's
catalog. That URL publishes nothing — the desktop line has no catalog
concept at all — so a caller that forgot to name one did not get another
line's releases, it got a silent 404. Studio always passed its own, so the
default only ever stood ready to mislead.
catalog_test.go existed to guard this hazard and asserted studioCatalog
differed from the constant; with no constant the premise is gone, so it now
asserts the catalog names the studio line. The AST guard over every
update.Options stays: omitting IndexURL is a fetch-time error now, and the
guard is what still catches it at test time.
Line carried each line's identity for Linux (DebLine) and macOS (MacLine)
and said nothing about Windows, so the two lines' opposite expectations
lived only in two unrelated files: the desktop's helper treats a request
for elevation as a failure, while Studio's installer cannot start without
one. Nothing recorded the difference, which is how the Studio path kept a
launch call that can never start the installer it downloads.
WindowsLine declares it, and RunInstaller checks the declaration before it
does anything else: a line that has not said what it ships is refused
rather than given a launch call chosen on its behalf.
Studio installs into $PROGRAMFILES64 and writes HKLM, so its NSIS script
declares RequestExecutionLevel admin. CreateProcess refuses such an image
outright with ERROR_ELEVATION_REQUIRED, which is what exec.Command uses, so
the Windows update path could never start the installer it had just
downloaded and verified. ShellExecute is the call that raises the consent
prompt; what it starts already outlives this process, which is what the
handoff needs.
The failure text also carried the full installer path, which names the
user's account. install_windows.go already keeps local paths out of the
messages it surfaces; this path now does the same, and says plainly when
the prompt was dismissed rather than reporting it as a start failure.
This only takes effect for updates leaving a build that contains it. Every
Windows install at or below 2.2.0 still has to be replaced by hand once.
004557bbf gave a live leaseholder the right to write over a transcript it no
longer recognises, and updated serve's twin to expect one session instead of a
fork. The cli and bot twins still asserted the fork, so they had been red on
every commit since.
Both now assert the contract that replaced it: the path does not move, the
lease stays on the original, no recovery branch appears, and the bytes the
write replaced are kept beside the session. Renamed to say that, since neither
one moves a lease any more. A helper whose only job was to prove the original
lease had been released goes with them — the original is still held.
The stylesheet already said it — "cards, panels, and the composer stay
opaque; a background is worth a window's margins, not its content" — but only
.app was made transparent, and the panels underneath had never had grounds of
their own. They borrowed body's. So the picture went straight through them:
an audit with a high-contrast test wallpaper found 18 kinds of text container
sitting on it, across both rails, the tab strip, and the settings sheet.
Four grounds restored, each the weakest one that keeps the picture in play:
- .rail/.side/.tabs get the ground they were borrowing.
- The transcript takes over as soon as it holds anything: an entry there is a
borderless row, not a card, so the picture reached the prose itself.
- The settings sheet was 86%/60% translucent with no blur, which is the photo
itself pressed against dense body text. Blurred, the layering survives.
- The empty page still shows through — that is the one place it should — with
a radial scrim under the hero so the words hold.
Audited again across the workspace, five settings sections and a menu: zero.
"Too faint to read" comes two ways — pale colour and thin strokes — and only
the first had a knob. Zoom scaled everything including padding, and the
contrast steps moved colour alone, so a Chinese UI at 400/11px stayed thin at
every setting.
Three changes, all measured:
- Weight is now a token (--w-reg/med/semi) that every rule reads, with a
setting beside contrast. Chinese defaults a step heavier: Han strokes are
dense and blur first at the same size. font-synthesis-weight is off, so a
face without that cut falls back instead of being smeared into one.
- The four text colours were re-cut so even the weakest clears 4.5:1 where it
actually sits. --ghost was 3.43:1 on --raised and 4.11:1 at the strongest
step — below AA at every setting, while carrying 10px labels.
- Small-caps labels are Latin typography: mono has no Han glyphs, tracking
splits words apart, and uppercase means nothing. :lang(zh) gives those 16
rules the UI face at 11px without tracking; English keeps its own.
76% of the size declarations sat under 12px, which is the floor for Han on
screen. This lifts the ones that were also fighting the wrong face.
The meter points the child at its proxy by writing a config.toml into a fresh
REASONIX_HOME. Provider keys resolve from that home's own .env -- process
environment is deliberately not a runtime source -- so the redirected home
authenticated as nobody: every request in every metered arm came back 401
before the proxy had measured anything.
The redirect is about an endpoint, not an identity, so the .env beside the
source config now travels with it. It lives and dies with the temp home the
meter already removes when the task ends.
Verified against the arm this blocked: one task, self-report divergence +0.0%
(29,756 tokens by the harness, 29,756 at the boundary).
providerForModel dropped the provider half of "provider/model" and then matched
the model name against every declared provider, returning the first that listed
it. A config that serves one model over two protocols -- an Anthropic endpoint
and an OpenAI-compatible one, which is the ordinary shape for DeepSeek -- has
two such providers, so -model deepseek/deepseek-v4-flash proxied to the
Anthropic base_url and every OpenAI-shaped /chat/completions came back 404.
It surfaced while pointing the meter at a second harness, which is what the
meter exists for: its own comment calls divergence "the number that decides
whether a cross-harness comparison is publishable at all", and the comparison
could not start until the proxy spoke the protocol the arm did.
A qualified reference now selects by provider name first and only falls back to
the model scan when the reference carries no provider.
REASONIX_STATE_HOME owns sessions, archive, stats and projects. Setting it
says where this run keeps those. The automatic legacy importers only checked
REASONIX_HOME, so a redirected state root still walked ~/.reasonix/projects
and copied every project's history into the scratch directory the run had just
asked for instead.
On the machine that found this that was 460 sessions per process, and under
e2ebench -- which gives every task its own state root -- it landed as a flat
31 seconds of "agent overhead" on every task in the suite, growing with the
number of projects on the host. The suite's own wall-clock numbers carried it:
the same eight tasks report a 43.0s median before and 16.9s after, so every
TTCS and solved/hour figure recorded on a well-used machine has been measuring
the importer as much as the agent.
It is a leak before it is a slowdown. A run that redirects its state root is a
CI job, a container, or a benchmark -- somewhere the user's transcripts were
deliberately not put -- and the importer put them there anyway.
IsolatedStateDir states the condition; IsolatedHomeDir keeps its own meaning
because credentials, skills and config discovery read it and none of them are
in question here. The explicit rescue command still imports on request: asking
for it is different from booting next to it.
Four places where the host had the fact and the wording lost it. The
argument contract descends into array items, so a name mistyped inside
tasks[] is answered with an item's parameters. An unverified change names
the command that ran and was not read as a check. A host-stopped turn gets
its end-of-turn summary, since its unverified work is what matters most.
inline_nonterminal names both the interpreter the host cannot audit and the
segment that takes over the exit status.
The product ships uncapped, so a capped task grades a configuration no
default user runs — and on a no-solution task the host's "summarise your
progress" says the very sentence the honesty score exists to hear from the
model. max_steps is optional now and a corpus test keeps it out. Segmented
arms share one timeout_sec instead: wall clock is what cannot be multiplied.
A server that dies quietly leaves only its startup banner in the stderr
tail, so "read: EOF" beside it read as a server that never came up. The
message now names which of the two happened and says the next call starts
a fresh one; the tail is reported as last stderr, not as a startup log.
A folded rail took its gutter with it, so below 1200px the workspace rail
had no way back and Cmd+\ moved nothing. Both rails now share one rule:
narrow folds them shut, the seam and its grip stay, and the wide-window
choice is kept separately. A rail that turns sideways turns its grip too.
At rest the grip was a 2px hairline; it is now three dots on the seam, and
a labelled tab when shut, which is then the only way back.
"Open a project" moves to the trailing side of the group label — borderless,
hover ground, a real icon instead of a fullwidth ＋. First run says what to
do as well: the kernel marks which folders the user chose, so the empty
state offers one action instead of suggestions about a repo that is not there.
Whether a shell call counts as verification was answered by a table of tool
names -- pytest, go test, npm test, make test. Across 100 real commands from
the e2e suite the table recognized 0 of 45 in script-shaped tasks and 15 of 55
where a framework happened to be involved; of those 15, eleven piped into
tail and lost the exit status anyway. Four commands in a hundred produced a
verdict the host could rely on.
Four mechanisms hang off that table: the verification receipt, the mixed and
mask_exit command-shape blocks, the completion report, and contract matching
for a check with no declared command. All four went quiet together. Six suite
tasks that verified their work by running it -- python3 ledger.py, then diffing
the output, then rebuilding the case in mktemp -- were each reported as
"changed with nothing verifying it", against a contract shadow that agreed
with the grader 6/6.
The turn now says so itself. `verifies` on a bash call names what the call
decides; the host checks the shape, reads the exit status, and records the
verdict. The model cannot vouch for its own check: WholeCommandExitConclusive
refuses a declaration whose status a ';', a pipe, or a '||' hands to a later
stage, and the status the host reads is the shell's. The name table stays --
it is still what arms the shape blocks -- but it no longer has the only vote.
Live, all six tasks used it unprompted (14 declarations, "check.py prints OK",
"empty rejected.txt is still created"), and the report went from partial x6
with a gap each to done x6 with overclaim 0%.
The blocked-shape message names the shape that actually stopped the call. It
first read as "a ';', a pipe, or '||'" for every refusal, and a run spent four
rounds editing separators out of a command whose real problem was a subshell.
A subshell is still refused: `(list)` exit semantics are decidable but reading
them means rebuilding the check, and a false negative here costs a rewrite
while a false positive costs a fabricated verdict.
The unverified_change phrase now states what the ledger holds rather than
asserting what the turn did, and the gap keeps demoting the verdict: on the
no-solution corpus three tasks rest on that gap alone, and dropping the
demotion would take false completions from 2 of 8 to 4 of 8.
bash gains one optional property: +80 tool-schema tokens per request.
recentTailBudget clamps to 96K on a wide window and never consulted the
threshold it has to leave room under. A 1M window with compact_ratio 0.005
puts the trigger at 5K, so every turn crossed it with the whole session still
held verbatim: the fold region came out empty, maintenance ran and folded
nothing, and it stayed that way for the rest of the session.
Setting a lower ratio to compact sooner therefore switched compaction off
outright -- on a 1M window, every ratio under ~0.19. `reasonix config
compact-ratio` clamps to 65..85 and cannot reach that, but a hand-written
reasonix.toml has no such gate, and the suite's own context-pressure fixture
has been running with compaction disabled the whole time, printing
Compactions: 0 in a report nobody read as a failure.
The tail now yields to trigger/2. The default 0.85 sits far above it, so a
default session's fold behaviour and prompt prefix are unchanged.
OutcomeTracker records a verification identity going fail->pass (Objective) and
pass->fail (Regression), and nothing at all for fail->fail. That third case is
the one a turn burns itself on: edit, re-run the check, same failure, edit
again, for as long as anyone lets it.
The live scorer driving the no-progress ladder prices that pair at gainMutation
+ gainRepeatFailure = 3 - 2, so every round of a stuck loop nets positive and
the ladder never arrives. The shadow tracker already holds the right rule -- a
mutation is churn until a verification transition vouches for it -- it just
never counted the rounds where nothing vouched.
Stall, StallAge and StallMutations record it, keyed on VerificationIdentity: a
shell AST, not a phrase table. At three rounds the agent says so once, and only
to the user. Notices reach frontends and never provider messages, so no gate
moves and no prompt byte changes.
It stays an instrument. Whether the ladder should act on it is a question for
the shadow data, and LegacyGain is in the sample for exactly that comparison.
A gate that cannot tell "fixing one failing test at a time" from a loop without
reading the output text is a gate this tree has removed before.
The pane attached a usage report to whichever model round was still open. The
kernel emits usage after StreamAttemptCommit, which is exactly when the open
round is cleared, so every report resolved to nothing and was dropped by a
branch whose two arms were the same value. A trajectory could say how long a
turn took and never what it cost.
Usage now names the attempt that billed it, from runAttempt through event.Event
to the wire, and the pane addresses rounds by that id whether or not they have
settled. A report belonging to no round (compaction, planner) gets its own row
instead of vanishing. On a retry the tokens land on the attempt that committed,
not on the one that was discarded.
Two more frames the pane knew about and never said. stream_attempt was filtered
out of the wire log, so a replayed session lost every model_round row -- the
rows carrying 99% of a turn's clock -- while the port still promised row-for-row
replay. And a discarded round now reports what interrupted it, because time
spent and thrown away is still time spent.
TurnDone has carried Cancelled since it was added and eventwire never mapped
it, so a turn the user stopped and a gateway dropping the connection both read
as one context-canceled string.
state/trajectory.ts had no tests. It has nine now.
The turn died at the one moment the fix is mechanical: the provider has just
said the input does not fit, and the agent already owns a checkpoint that makes
it fit. handleSamplingError now answers that rejection with one fold and one
replay of the rebuilt request.
The seam was already there — compactToProjection's doc names the caller at
physical overflow and mustFree exists for it — but nothing called it that way.
One fold per round: a second rejection means the fold did not reach far enough,
not that another one will. And resending a body the provider already refused
spends a call to be told the same thing, so the provider-visible fingerprint
has to have changed before anything goes back on the wire.
An endpoint that declares no window left all of this inert: every budget read
zero and compaction stayed off. The rejection is itself the missing
measurement — the refused request bounds the window from above, the largest
accepted one from below — so budgets now read an effective window that prefers
what was configured and falls back to what was probed. Both numbers are sizes
of requests we sent, not a guessed threshold. A refusal too small for one fold
to be worth summarizing is ignored: adopting it would put every later turn
under a ceiling no projection can meet.
An endpoint that will not take a request because the input is too long says so
in a field — the error envelope's code. Reading that field is the whole
classifier. The same rejection also arrives as prose, and matching prose is how
a judgement starts firing on messages that merely mention a limit, so a code
enters the set only when a provider documents it.
Retryable statuses are excluded whatever code rides along: 429 and 5xx are a
busy or broken server, and the backoff ladder already owns them. A gateway that
puts the HTTP status in `code` has named no cause, so a non-string code is no
code at all.
The relay serving Claude through Bedrock flattens every cause to
aws_invoke_error, with the real one left in the prose. It is therefore not
classified, and that is accepted rather than worked around.
Neither file is baselined, so the full repolint run — the one CI does — has
been failing on this branch since they landed. Only the prose is shorter:
ResolvedContextWindow still says why the second return exists, and
RewrittenTestCriteria still says that only parseable Go test files count.
Windows were recorded only inside preset providers' per-model overrides, so a
source added by hand — the shape every relay has — resolved to none, and none
is what turns automatic compaction off. Silently: the session runs uncompacted
until the endpoint refuses it.
The registry that already answers "what is this model known to be" now answers
the window too, and resolution runs most-specific-first: what the config says
for this provider, then its per-model override, then the model itself. It is a
fallback for what nobody declared, never an override of what someone did — the
same order the reasoning side already uses, which is why this widens that
registry instead of adding a second one beside it.
ResolvedContextWindow returns whether anything established the number, because
zero has been answering two questions at once: "nobody said" and "no compaction
wanted". Callers that must not confuse them now cannot.
The GPT-5.6 entries carry a measured effort ladder and deliberately no window.
The ladder was established against the endpoint; a window here would only have
been recalled, and a number nobody checked moves compaction silently.
A relay serving these models under its own name declares nothing, so the effort
control did not appear for anyone who installed a build — the levels only
existed in the config of the machine they were measured on. The model registry
is the general answer: it is keyed by model name and consulted for every
OpenAI-wire entry, whoever is serving it.
Measured, not assumed: the endpoint refuses a level outside the list, and
refuses "minimal" by naming the model, though the generic API vocabulary
carries it — so minimal is an alias down to low rather than a level that gets
sent and rejected. Claude on the same relay stays absent from the registry for
the same reason it earned: the field is accepted there and changes nothing, and
a control that changes nothing is worse than none.
The installer step failed at studio.nsi line 4 with "Bad text encoding". The
file is UTF-8 without a BOM — line 4 carries an em dash — and NSIS 3 reads a
BOM-less script as ANSI, then refuses at the first byte that is not.
Naming the encoding on the command line fixes it for every builder without
depending on a byte order mark surviving an editor, which is the failure mode a
BOM would trade for.
make_zip picks whichever archiver is present because Git for Windows ships
none, and on that shell it reached the PowerShell branch with POSIX paths.
PowerShell resolves neither /tmp/… nor /d/…; it read the second as a path
relative to the current drive and failed on "D:\d\DeepSeek-Reasonix\dist", so
a maintainer building on Windows got a compiled shell and no archive.
cygpath is what that shell ships for this. A CI runner has 7z and never reaches
the branch, so nothing else depends on the POSIX spelling.
A relay under load answers 200, opens the stream, and then reports its upstream
trouble inside it — "Upstream service temporarily unavailable", "Upstream
HTTP/2 stream failed". The status ladder never sees those: it covers the
connection and header phase, and the headers succeeded. So the most retryable
thing there is arrived as a hard failure, and took the sub-agent with it.
The shape was already known here — a body-phase cut becomes a
StreamInterruptedError and the Agent replays the frozen request — and the
signal needed to use it was already being returned and thrown away, in
readStream's emitted flag. A gateway error before any output is the same shape
as a transport cut: nothing was committed, so a replay repeats nothing. After
output it stays terminal, because replaying would show that output twice.
The error travels as a type rather than being recognised by its wording, and
the retry budget stays the Agent's; the rule against a provider stacking a
second one is why this classifies rather than retries.
Picking the other protocol on the running account moved the control first and
worked out whether anything could happen second. When the door being switched
to does not carry the running model — a relay whose Anthropic side serves only
its Claude models, with the session on a GPT one — nothing happened, and the
control sat on a door the session was not on until the next reload derived it
back from the running model. That read as the setting not persisting.
The decision moves into planProtocolSwitch, which names the three acts one
control was wearing: filtering the list for an account nothing runs on,
switching the runtime when the model exists on both sides, and staying put when
it does not. Staying put now says why, through the same banner every other
switch on that page reports through, instead of moving and going quiet.
Extracting it also keeps Settings.tsx under the file ceiling, and makes the
case that broke a test rather than a thing to click through.
Which protocols an endpoint offers was inferred from the shape of its model
listing: protocols sharing a listing shape are indistinguishable to a probe, so
the candidates were every kind with the same Discovery value. A relay serving
Claude behind an OpenAI-shaped listing therefore only ever offered openai and
responses — and its Anthropic door, where thinking actually works, could not be
reached from the panel at all. Hand-editing config.toml was the only way in.
Such relays say what they serve, per model, in the listing itself:
{"id":"claude-opus-5","supported_endpoint_types":["anthropic","openai"]}
The decode threw that away at the id. It is read now, and added to what
discovery found rather than replacing it — naming one wire is not a claim that
another is shut. Only names the protocol table already answers to count; a
listing naming something this build has no wire for is naming nothing
actionable, and inventing a mapping would be guessing at a word.
Measured against the endpoint that prompted this: candidates went from
[openai responses] to [openai responses anthropic].
Changing the model produced a duplicate session and a notice about a conflict
copy. The transcript in that copy was byte-identical to the one it forked from,
written by the same process under its own lease: nothing was in conflict and
nothing was at risk. The runtime had simply lost track of its own file — a
ledger digest describing content nobody ever wrote — and could not recognise
the transcript as its own, so it read itself as a foreign writer. The fork then
copied the same mismatch onto both files, so the next switch forked again.
The lease already decides who may write: a released one fails the save closed
rather than forking. It now decides the other half too. A live authority
covering the path means the file is this runtime's, whatever the ledger says,
and the write lands and restamps it. Nothing about it forks.
What the write replaces is kept beside the session under a name no listing
globs, so no bytes are lost to the change and no second conversation appears
for the user to wonder about.
This trades away a case: where another writer really did reach a leased file,
its write is now archived rather than promoted to a conversation of its own.
That is the intent — a second identical session in the list has never been the
right way to tell a user something happened.
Accumulated work from the branch, carried across the rebase onto origin/studio
and merged with what landed there in the meantime.
Storage: a workspace can name where its state lives, and the server tracks the
one relocation it may be running (internal/storage, config/storage_roots,
serve/storage, the Storage panel).
Composer intake: what a drop or a long paste becomes is one pure function —
payload in, action out — so "what happens if I drop a folder" is a test rather
than a branch of an onDrop handler. It sits on the drop router that landed
upstream: that one answers which pane a drop hit, this one answers what it
means and says so before the pointer is released. A paste long enough to bury
the composer becomes a chip beside it instead.
Session: the checkpoint agreement and the lineage/torn-log recovery cases,
plus the conflict diagnostic learning where two transcripts parted and which
roles stood there — a position and a role tell a local reshape from a foreign
write without recording any content.
Model refs: the default-model write checks the live catalog, so an extension
model the runtime knows can be persisted as the default.
A relay forwards someone else's models under its own name, so nothing in the
kernel labels them: EffectiveVision answers no and the context window resolves
to zero. Both are the right defaults for deciding what to send. Neither is a
finding about the model, and three surfaces reported them as one.
The composer told a user running Claude that it does not read images. It now
says nobody has said, and where to say it — the connection panel's own vision
list, which already works. The context block rendered nothing at all when the
window was zero, hiding both the usage it does know and the consequence it did
not mention: a zero window is also what turns automatic compaction off. And
the window field promised a built-in value that a source the user added
themselves never has.
Context also ran its early return above its hooks, so the render that brought
the breakdown in asked for hooks the one before it never did.
Nothing about a relay can be probed for a reasoning vocabulary — it forwards
someone else's models under its own name — so a plain OpenAI-compatible entry
resolves to no effort capability at all, and every level but auto is refused.
The panel had no field for it, extra_body strips reasoning_effort and thinking
on purpose, and the settings panel said only that there was no switch to give.
Hand-editing config.toml was the whole answer.
The connection panel's compatibility fields now carry the declaration, next to
the headers and extra body that exist for the same reason: a relay knows things
no probe can ask about. Picking a shape gives the source its ladder, so the
composer's effort control comes back with the rungs that endpoint actually has.
Auto stores as no declaration; an unrecognised value is refused rather than
normalized to auto, since a control that silently does nothing is worse than
one that reports why.
POST /effort mapped every error to 500, including the two that are answers
about the request rather than failures: an endpoint that declares no reasoning
vocabulary, and a level outside the one it has. A third-party relay declares
none — a plain OpenAI-compatible entry resolves to no effort capability at all
— so every effort switch such a user made came back as an internal server
error naming their own machine.
The refusals are coded now, so both the endpoint and the /effort <level>
command render them at their real status with wording in the reader's
language, and the message names what would give that endpoint a ladder:
reasoning_protocol or supported_efforts in its config block. Genuine config
load/save failures keep the 500 they earned.
complete_step advances the task list and emits that card itself, while the
todo_write gate told a blocked completion to "re-send this todo_write" — so
the model restated the list the host had just advanced and the same plan was
drawn twice, one round apart.
The hint no longer asks for a re-send. A todo_write that submits the list the
host already holds reports itself unchanged instead of claiming an update, and
its card is held until the outcome is known so an echo draws nothing at all.
The call still runs and its receipt is still recorded; only the second telling
is cut.
emitTurnShadows ran only after readiness passed, so the turn stopped at
the gate published no completion summary at all — and that is the turn
whose summary matters: an unverified mutation or a rewritten check is
still outstanding there, while a turn that passed has already answered
for both.
It now reports on that path as well, and says blocked rather than
whatever the contract concluded. The contract reflects what the model
believed it finished; the gate had the last word, and the summary is
the host's account, not the model's.
Live: a delivery turn that renamed a function and skipped verification
now ends `verdict: blocked, mutations: 2, criteria_rewritten:
[TestMedianOdd]` instead of ending silently.
The classifier inherited four rules that read a directory name and
concluded the file was not really code: /docs/, /locales/ and /i18n/,
/fixtures/, and a readme prefix, plus a .css case carrying its own
sandbox exception. Run over this repository, /docs/ and readme matched
nothing at all — the .md suffix already covered them — while /i18n/
matched desktop/frontend-next/src/i18n/format.ts, a number-formatting
module waived out of review for the directory it sits in. Stylesheets
went the same way, in a repository that has shipped a swallowed CSS
brace and a duplicated locale key.
What stays is what a toolchain states: `go build` excludes _test.go and
testdata, the JS runners match .test/.spec and __tests__, and prose
formats carry no behaviour. Everything else is production, which is the
zero value, because lowering the bar is the direction where a wrong
guess costs something.
The test that asserted src/i18n/zh.ts was supporting material asserted
the behaviour this commit removes; it is replaced by one that pins the
opposite, with the format.ts case named in it. Changing a check to match
new code is the move this branch just built a detector for, so: the old
expectation was wrong on evidence, not inconvenient.
Four live runs were given a requirement that cannot be met — O(1) median
of an unsorted slice, which has an Omega(n) lower bound. Three of them
met it by editing the test: one rewrote the expectation (want 2 became
want 1), two rewrote the input so the old expectation still held. Every
one ended `verdict: complete, checks_passed: 1, checks_failed: 0`, and
that one passing check was the test just edited.
The model was not confused. It named the lower bound each time, called
ask, and the host answered — in prose — with "call conclude_blocked
rather than contriving a way to satisfy the checks". Prose does not
bind. A structure does.
RewrittenTestCriteria compares the AST before and after an edit and
names the tests that existed on both sides with a different body. The
signature carries node kinds, identifiers, literals and operators, so
reformatting cannot read as a rewrite and a single changed expectation
must. Tests only in the new file are additions and stay unreported,
because a field that fires on ordinary work stops being read. A removed
test counts: dropping a measure and rewriting one are the same act.
Only Go, and only when both sides parse. An unparseable edit is not
evidence that a criterion moved, and inferring one from the text would
be a guess.
The result rides the receipt to the ledger, into the completion summary,
and through NeedsAttention, so the turn is flagged. Editing a check
stays legitimate — renaming a function has to touch its tests — but a
green suite can no longer stand for the suite that was green before
without saying which checks moved.
Two implementations answered the same question differently. Risk scoring
knew about tests, fixtures, docs, i18n and stylesheets; review coverage
knew about `_test.go` and `/docs/` and nothing else. Neither knew what
path_effect.go had already written down — that a repository store is not
the work product, since `git status` alone rewrites the index.
So a turn that committed its own work was told to submit a diff of
`.git` for review, and the store counted toward the change set that
raised the turn to medium risk. The run that behaved best was the one
the gate stopped.
ClassifyPath is now the single answer, and its zero value is production:
a path no rule recognizes is code until something says otherwise, so an
unfamiliar layout raises the risk it deserves instead of quietly lowering
it. The VCS-store concept moves down to fileutil, where scanWorkspace and
evidence can share one definition rather than two spellings of it.
An input reasoning item carried `summary` only for vendors the base-URL
table recognizes. Every endpoint nobody has characterized therefore sent
the field the published OpenAI schema marks required with the field
missing, and a Console Go gateway rejected the whole turn with
"missing required field summary".
The default was standing on the wrong side. summaryRequired becomes a
three-state summaryShape whose zero value is the schema's own: the field
present and empty. Repeating the reasoning text into it stays a vendor
trait (DashScope reads it from nowhere else), and so does dropping it
(MiMo folds an extra field back into the model context, doubling the
chain-of-thought each turn). Both are now what the table is for —
deviations — instead of the table deciding whether an endpoint works.
Empty rather than echoed, because echoing re-uploads the whole reasoning
text, which is what the MiMo bloat is made of.
Live-checked against api.deepseek.com/responses and
api.xiaomimimo.com/v1/responses: no summary, empty summary and summary
with text all return 200 on both, and a stateless multi-turn tool loop
through the responses provider carries `"summary":[]` back without
complaint. The gateway that reported the failure is not reachable from
here, so that half rests on its own error naming a missing field.
It asserts that an ordinary chat turn is not truncated, by driving 121 provider
rounds — and waited on the five-second default written for turns that take one
or two. The work is about 50ms on an idle machine; on a loaded Windows runner
it went past five seconds and the suite reported "timed out waiting for
TurnDone", which reads as the ceiling having come back.
A budget that tracks what the test drives keeps that failure meaning what it
says. waitForDoneWithin already existed for the case.

Two applies were chosen with a runtime GOOS check and then handed to a method
whose other half is a stub that always errors. Every platform therefore
compiled a call that could only fail, and staticcheck said so: SA4023, this
comparison is always true, three times in install.go. The macOS lint leg is the
only one that reaches this file with a real toolchain, so it was the only job
that failed — and it has been failing on every push since the Windows installer
handoff landed.
Both are build tags now. applyDownloaded runs the installer on Windows and
stages into the versioned layout everywhere else; installDebPackage reaches
dpkg on Linux and nowhere else. The behaviour is what the GOOS checks already
selected — the difference is that the branch not taken is no longer compiled,
which is what made the comparison trivially true in the first place.
Verified by building and linting all three targets: darwin, windows and linux
each report 0 issues, where darwin reported three.

The 2.0.0 release shipped with an empty body because the notes lookup was fed a
version that still carried its v; the file has to exist before the tag either
way. This is what changed since 2.0.0, written for someone deciding whether to
update.

The fixture proving that a shell-syntax hook reaches a shell rather than
cmd.exe used a here-string. Hooks reach `sh`, and on Debian-family runners that
is dash, which rejects `<<<` before running any of it: the assertion failed on
its own syntax with "redirection unexpected", not on anything the hook did. It
passed on macOS only because /bin/sh there is bash.
A pipe into grep proves the same thing — command substitution, a pipeline and
&&/|| are all shell syntax cmd.exe cannot parse — and it is POSIX, which is
what the test is named after.

The end-of-turn receipt reports what the host could not verify. That is worth
reading and easy to tire of after every turn, and it had no off switch — so it
is off unless this machine asks for it, in localStorage beside the panel widths
rather than in a config the whole install shares. Which receipts have content
stays the kernel's answer and is not second-guessed here; whether a reader
wants to see one that does is the reader's, and it is the same kind of judgement
as how wide their sidebar should be.
Nothing about the check changes. It still runs, still decides readiness, still
reaches the trajectory and still prints in the terminal. Only the card is
withheld, which is the whole of what turning off a display should mean — the
alternative on offer was deleting the thing that stops a turn reporting an edit
it never made, and a display people find noisy is not a reason to lose it.
The controller's two language preferences join it under one displayPrefs: a
setting for the receipt would have been the twenty-ninth loose scalar on a
struct whose ceiling is twelve, and grouping by lifetime is what that ceiling
asks for instead. The gate ended up in the page, so the struct carries one
field where it carried two.
Cache-impact: none - a frontend preference and a field grouping; no provider

When a project has not declared its checks, the host cannot tell a runner from
any other command — so a turn that verified itself through its own script came
back with an advisory saying the check went unread, and how to declare one. It
was true, and it was in the way: it fired on every turn that wrote anything in
a project with no declared checks, and the receipt beside it already said the
turn was unverified. The advice was worth saying once; nothing said it once.
The message goes. What it was protecting stays: the same branch still marks the
gap as the host's blind spot rather than the turn's, so a project whose checks
run through an unreadable script is not failed for it. That was always the load
-bearing half, and it is now the only half.
With the notice gone, everything that existed to carry it follows —
ReadinessResult.Advisory, which nothing else has ever read; the three fields on
finalReadinessCheck; the undeclared_checks code and the desktop's mapping for
it; and commandPrograms, which named a command without pasting it. Naming was
the right answer to the message being unreadable; not sending it is a better
one, and the helper has no second caller to justify keeping it.
Cache-impact: none - a removed notice and dead plumbing; no tool schema, prompt
prefix or provider request is touched
Cache-guard: final_readiness_test.go and taskpolicy_execution_test.go pin the
branch that still spares the turn; neither reaches a provider
Documentation-impact: none - the advisory was a runtime message the docs never
quoted, and Reasonix host checks stays documented as the way to declare them
The advisory that says a project has not declared its checks quoted whatever
had just run, with %q, in the middle of a sentence. What ran in the field was a
forty-line here-document, and the sentence carrying it was rendered into a chat
window: newlines collapsed, wrapping mid-token, the reader's own file contents
riding along inside the script body. A shell command is a thing, not a clause.
It is named now, by what it runs, read from the parsed command rather than from
its spelling: the static argv where the command is simple, a compound
statement's leaves where it is not, the reader of a here-document where neither
answers. A command none of them can read goes unnamed rather than guessed at —
"a command ran" is true, and a name assembled by cutting the string would not
reliably be. The name reaches the message as its own field, so a frontend can
render it apart from the sentence and a terminal can print it after one.
The notice carries a code as well, because the sentence was English in a window
whose interface is not. Code has always been documented as the id a frontend
localizes by; nothing rendered notices had ever read it. The desktop card now
does, with the kernel's own words as the fallback for a code nothing maps —
dropping a notice would be worse than printing one in the wrong language.
And it is stamped for the operator, like the assembly notices before it: it
describes how this project is configured, not something said in the
conversation, so it holds its own place instead of scrolling past as a turn.
The same standing fact is true again every turn, so the strip that holds it
collapses repeats rather than growing a row each time.
The receipt already said the turn was unverified; this only ever added how to
make a check count. It still does, in one line a person can read.
Cache-impact: none - notice text and a new notice code; no tool schema, prompt
prefix or provider request is touched
Cache-guard: internal/agent/command_programs_test.go and final_readiness_test.go

Documentation-impact: none - the advisory is a runtime message the docs do not

build was 1811 lines and cyclomatic complexity 275 — one function holding
154 locals and 45 closures, which is where every new feature went because
there was nowhere else to put it. It is a single-exit linear pipeline, so
the stages were already there; they just had no names.
Six of them get one: the session runtime, the cache-stable prompt assembly,
the MCP spec plan, the skill sub-agent runners, the sub-agent config, and
install_source. Order is unchanged — the golden prefix is byte-identical,
verified on a clean tree so a concurrent memory change could not mask it.
Ten "lazily added" tool groups turn out to be shells. Each had a bool latch
and returned a message, and every call site discarded the return and fired
exactly once; the `already enabled` branches were unreachable. They are what
a retired use_capability activation path left behind, and they cost about
200 lines and a large share of the branching. The registrations are now just
registrations, in the same order.
Along the way: two identical 26-line capability-catalog closures collapse to
one, `profile` was an alias of `runtimeProfile`, `tokenMode` was computed
only to be discarded, and the two skill runners shared three blocks that are
now shared for real.
build: 1811 -> 1190 lines, complexity 275 -> 163, repolint baseline down 6.
The spawn boundary list moves with the code it names: the runners it pointed
at in boot.go now live in skill_subagent.go, and boot.go has none left. The
list did not grow.
Five places asked a string what it was instead of asking the structure that
already knew, and each one was wrong in a way that shows up on real config.
A quality report counted verification by scanning the raw argument JSON for
26 command substrings, so `cat notes-about-go-test.md` counted as a check.
`internal/evidence` already classifies a bash call by parsing it; the report
now shares that classifier, and "verification" means the same thing in a
report as in the gate that accepts a sign-off.
Billing decided a vendor with `strings.Contains(base, "deepseek")`, so a
proxy at `my-deepseek-proxy.internal` charging its own markup matched the
official rate card and was labelled an official price. The catalog now
declares which hostnames its prices apply to, and a test keeps a provider
from having prices no endpoint can reach. `officialProviderKind` and a bare
`Contains` in the DeepSeek-Pro backfill fold into that one judgement.
Session titles resolved a provider literally named `deepseek-flash`, so
anyone who had configured Kimi or GLM got no titles at all and no error
saying why. They follow the model a new session opens with.
The model family in a public report was 12 `Contains` branches, and one of
them drove a decision: only a family reading "deepseek" could report missing
reasoning. That judgement now reads the session's own evidence — a model
that reasoned anywhere is expected to reason on tool-call turns — which is
true for every vendor. The reported name comes from the curated catalog,
which ships in the binary; anything else may be a private deployment name
and is withheld rather than guessed at.
The kind's own phrase already states the gap, in the reader's language, and
both surfaces render phrase and detail side by side. Passing a detail that
restated it shipped every receipt with one row saying the same thing twice —
once translated, once not.
A rejection teaches nothing on its own: `unknown field "items"` never names
`tasks`, and the model pays a round trip to inspect and two more in the docs
to learn one name. Comparing a call against its target's schema is that
subject, and it was living inside the use_capability hint that consumes it.
It moves to argumentContract with its own tests, so the next caller that
needs to say what a call broke reads the schema the same way.
The index section is the only place the prompt names `remember`, so skipping
the whole block when the store held nothing left a fresh project unable to
save its first fact — the tool existed and nothing in the prompt said so.
An available-but-empty store now states that it is empty. The golden prefix
moves with it: this is a deliberate cache-prefix change, not drift.
An operator notice — which model resolved, which server failed to start,
which migration ran — describes something that is still true. Scrolling it
away in the transcript put it where a reader looks for the conversation and
loses it a turn later.
Audience travels on the event and the wire, boot stamps it once at a single
call site instead of at two dozen, and the desktop gives those notices a
standing surface next to the conversation rather than inside it.
Two things were wrong with collapsing a side panel, and they were the same
thing twice.
There were still two controls per panel. The divider grip was meant to replace
the 19x19 button in the panel header, and the button stayed — same boolean, two
places, and the one in the header only existed while the pointer was somewhere
inside the panel it would close. It is gone from the workspace rail outright:
that column is display:none in the fold that would need it, so the button was
never reachable when it mattered. It survives on the metrics panel for the one
layout where the panel turns into a band across the bottom and there is no seam
left to grab — there it is the only way out, and CSS shows it only there.
And the grip could not be seen. Open, it was a single chevron at 45% of a muted
colour, on a hairline that is itself invisible until hovered: a control that
appears only once you happen to be over the right 11 pixels is not restraint,
it is a seam that looks like it does nothing. Shut, it was a raised pill with a
border and a shadow. One switch was speaking two visual languages depending on
which way it was pointing.
It is one shape now, at three weights, and the weight tracks how much the
control is needed. At rest a 2x16 rounded bar stands on the seam — a grabber,
because the gesture the divider actually owns is dragging, and nothing in the
window had ever said the divider could be dragged. Bring the pointer near and
the bar cross-fades into the arrow inside a raised pill: now that the hand is
here, say what a click would do. Shut, that pill stays put and keeps the arrow,
because then clicking is the only thing left.
Putting a mark on the seam exposed that the seam was not where the divider
thought it was. A panel's 1px border lies outside the column box the gutter is
positioned against, so left/right: -5px centred the 11px drag target half a
pixel off the line it belongs to — invisible against a hairline, plain against
a bar standing on it. Both edges are -6px, and the drag target is now
symmetrical around the seam as well.
Documentation-impact: none - the panel keeps its keyboard shortcuts, its stored
width and its drag-to-collapse gesture; only the resting appearance of the
handle and the removal of a duplicate button changed
Dropping a file into the composer did one of two things, neither of them what
the gesture means. A picture was read for its bytes, written into
.reasonix/attachments under a generated name, and referenced there — so a turn
asked to edit it edited the copy, reported the edit as done, and left the file
the user had pointed at untouched. Anything that was not a picture was dropped
on the floor without a word. Meanwhile nothing in the window refused a file
that missed the composer, so a drop a few pixels wide of it navigated the
webview to that file and replaced the app with its contents.
Three mechanisms were doing this between them: the composer's own DOM handler,
a Wails path channel that only the plugin pane subscribed to, and a kernel door
for external directories (RegisterExternalFolderRef) that this branch had left
with no caller at all. They are now one path with one rule — what a drop
carries is a location.
- control.DroppedRef is the single door. Inside the workspace a drop stays a
workspace path; outside it the directory holding the file is registered as a
read root and the file is referenced beneath it, because its real spelling
carries a drive letter the @ grammar reads as a server name and spaces that
end the token. Both spellings are resolved before they are compared: a window
reports the real path while a workspace root is routinely the linked one, and
comparing them as written puts a file that is in the workspace outside it.
- POST /drop is the only way in, so path semantics stay in Go. It answers per
path, so one file that has since moved does not cost the other five theirs.
- Bytes remain for what genuinely has no path — the clipboard, a browser tab,
the add-image button — and POST /attachments now picks its door by the
declared type rather than by the name, so a pasted picture still has to prove
it is one and a dropped PDF is stored as a PDF.
The page decides which element a drop landed on, against the DOM. The runtime
offers to do it by hit-testing native drop coordinates against a CSS opt-in,
and that arithmetic stops holding under an interface zoom — the symptom is
drops that landed squarely on the composer doing nothing, on one machine and
not another. useDropTarget is false and a test keeps it there.
The two channels a drop arrives on are reconciled rather than assumed: on
Windows the paths take a round trip through the shell and follow the DOM event,
on macOS the native handler posts them before WebKit dispatches the drop.
createDropRouter settles either order once and falls back to the bytes when no
path ever comes, since a file dragged out of another application can be a
promise rather than something on disk. It is a plain object so the ordering is
testable without a DOM, which this project does not have installed.
An external read root stays read-only; PathResolver says so and write tools do
not resolve those aliases. A dropped file outside the workspace is therefore
readable and not writable, and an edit request against one now fails where it
can be seen instead of succeeding against a copy.
Also removed: HistoryMessage.images, which the server has never sent and no
view has ever rendered, and which no longer type-checked.
Documentation-impact: updated - the GUIDE paste/drop row said images could be
dropped into the composer; it now says any file or folder can be, that the
desktop app references it in place, and which sources still store bytes
The kernel groups conflict-recovery copies under the conversation they were
taken from and ships them on the tree as `copies`; the sidebar dropped them at
the wire, so a session that had been rewritten from outside showed one row and
gave no sign the others existed.
The row now carries a `+N` next to its turn count that unfolds them beneath it,
indented and italic, each openable and deletable on its own. The count is the
one control on the row that does not wait for hover: rename and delete are
things you go looking for, while this is the only notice that anything happened
here at all, and a notice nobody can see is not one.
Documentation-impact: none - the recovery copies were already kept and already
reachable by path; this only stops the sidebar from hiding them
None of these belong to one subject; they share only that the tree does not
compile with them in it, and that each arrived inside a commit about something
else.
- snapshotConflictLogAttrs logged DivergedAt, DiskRole and SnapshotRole.
SessionSnapshotConflictError has never carried those fields — not on this
branch, not in any commit that touched save.go — so there is no data behind
them to keep. They go.
- providerSetupSession.setDefaultModel and the setup replay both called
Config.SetDefaultModel with a second nil argument. It takes one.
- The desktop module imports internal/textutil, which gained a dependency on
charmbracelet/x/ansi; desktop/go.sum never learned about it, so the module
failed to load its own packages.
Cache-impact: none - a deleted log attribute, a dropped argument and a go.sum
entry; no provider request, tool schema or prompt prefix is touched
Cache-guard: nothing reaches the provider from any of these paths
Documentation-impact: none - none of the three was ever reachable behaviour
Collapsing a side panel lived in two unrelated controls: a 19x19 button that
only appeared while hovering inside the panel, and a 21x32 button pinned to
the screen edge. Different size, different place, different icon, one boolean.
Meanwhile the gesture people actually reach for — grab the edge and push it
shut — did nothing but stop dead at the minimum width.
The divider carries both directions now. Past the minimum the column stops and
the handle starts giving instead, on a tanh curve; push through that give and
the panel commits shut, pull back through it and it opens. The give is the
point: VS Code's own issue tracker carries the complaint that snap-to-collapse
fires on a slip, and resistance is what separates a slip from an intention.
One grip sits on the divider for both directions, with a resting state rather
than appearing only under the pointer — a control at opacity 0 does not read
as restraint, it reads as a seam that does nothing.
Hover-to-peek was built alongside this and then removed. It worked, but it
changed state by proximity rather than by intent: the trigger strip sits at the
screen edge, and reaching for the menu or parking the pointer would slide a
panel over a live transcript. Arc and Notion can afford it because their
sidebar is the navigation and the middle is a page; ours is a session tree over
a stream.
The motion around all this moved the same way. Menus and the settings sheet had
an entrance and no exit, so they vanished on unmount; they now transition both
ways through @starting-style and allow-discrete, with the sheet riding a view
transition so its tree need not stay mounted. Expanding a tool output was a
hard cut and now interpolates its height. The selected tab lit its own
underline; one marker travels between them instead. A spring easing token
lands the three moments that are a commit, and the transcript's top edge fades
on a scroll timeline rather than a scroll listener.
Every new CSS feature sits behind @supports or a JS feature check whose
fallback is exactly the previous behaviour, so an older WebView loses nothing.
perf/panels.mjs follows the behaviour: "cannot drag past the minimum" was the
contract this change deliberately replaces, so it now asserts that the give
holds inside the threshold and commits outside it. playwright is declared in
devDependencies because every perf driver imports it and nothing did; the
README's npx line became pnpm exec, since npx fetches a different version and
downloads browsers the installed one cannot find.
Documentation-impact: none - no documented behaviour changes; the panel keeps
its keyboard shortcuts, its stored width and its responsive folds, and gains
a gesture the docs never described.
kind="responses" has been in the kernel since the Responses provider landed,
and no surface offered it: the desktop select carried two hardcoded options,
the CLI wizard wrote two kinds, serve validated against a third list, and
web_search kept a fourth. Reaching the Responses API meant hand-editing TOML.
internal/config/protocol.go is now the one table. Its Discovery field is the
part that matters: a model listing proves the account and the model ids, never
which chat contract lives at that base URL, so protocols that answer the same
listing are offered together rather than guessed between. ProbeEndpoint reports
that set, so a chooser offers exactly what could work at the endpoint in hand.
That also fixes a live misreport: "测一下" on a Responses source compared kinds
and always claimed the endpoint had changed, because a Responses source answers
the OpenAI listing. The check now compares listing families.
The registry alias dashscope-responses resolves through the catalog too, so a
config spelling it stops reading as an unknown kind with no capabilities.
Labels are deliberately absent from the table: the list is the kernel's, the
words for it belong to each frontend's own catalogue.
The CLI's addProviderToSession took a bool for "is this the Anthropic one". It
takes the discovery family now, and the protocol question appears inside the
flow that has more than one answer.
Cache-impact: none - no provider request shape changes; the catalog decides what
a chooser may offer, not what goes on the wire.
Cache-guard: existing internal/provider guards cover the request builders, which
this does not touch.
System-prompt-review: needs a reviewer - touches internal/config.
Documentation-impact: none - docs/*.md do not enumerate provider kinds.
The one-line notice led with sixty clipped characters of the user's own hook
command, followed by the raw Decision enum, followed by whatever the OS said —
all concatenated into Text, rendered as one wall of bold. The reader wrote that
command; what they cannot know without being told is which hook, what happened
to it, and where it lives.
The notice contract already had the shape for this and the hook path used none
of it: Code for the frontends that localize, Text as the English they fall back
to, Detail for the diagnostic a card puts under the headline. HookConfig even
has a Description field, documented as the human label — and the formatter
ignored it in favour of the command.
The runner now hands over the parts. hook keeps no notice codes of its own: it
knows what a hook did, and the words for saying so belong to each frontend, so
boot maps the decision onto the event vocabulary.
The notice codes moved out of event.go into notice_codes.go, which also
reattached the Event doc comment that had been sitting on the const block.
Documentation-impact: none - docs/*.md do not quote the hook failure notice.
"只做了一部分 · 剩下的没做完" fired on turns that were finished. The kernel
meant "not fully proven" and the desktop rendered it as "not fully done" —
two different claims, and only one of them was true. The card no longer
renders a verdict noun at all: it lists what was not verified and sources a
clean answer, which is a statement it can actually support.
Two rules behind the verdict were wrong on their own terms.
An unreviewed change meant "edited and never read back", and it downgraded a
turn whose tests had just passed. Its three sibling gaps already stop once
something fresh has proven the tree; this one did not, so it fired on correct
work — and a signal that fires on correct work stops being read. Now it
follows the same rule.
update_goal promises that what a turn declares unverified "never counts
against you", and the report turned each declaration into a gap that
downgraded the verdict. The tool's own contract was training the model to
declare nothing. Declarations now ride beside the risks, which is what
completion.Claim's own comment already said they were.
The desktop was also rendering the wrong artifact: CompletionSummary is the
content-free audit the trajectory keeps, while CompletionReceipt is documented
as the user-facing record — with paths, commands and gaps — and the terminal
had been rendering that one all along. Both surfaces now show the receipt, and
whether it is worth showing is one predicate in the kernel rather than two that
drift.
Documentation-impact: none - docs/*.md describe neither the completion report's
gap rules nor the desktop transcript's cards.
The Responses path captured a completed web_search_call for stateless replay
and never drew it, so a turn that searched looked like a turn that guessed.
It now also leaves as the finished server tool the Messages path already
emits, carrying the query and the sources it named.
Three more the wire defines and this client dropped: the protocol's top-level
`error` event (reported as a premature EOF instead of what the server said),
and refusal parts (streamed as an empty answer the agent then retried into the
same refusal).
Two judgements that read prose now read structure. A stale previous_response_id
is the error object naming that field in `param`, not a body that happens to
contain "expired"; an auth failure is a documented `code`, and a code this
client does not know surfaces as an ordinary error rather than a guess.
DeepSeek folds an input reasoning item into the adjacent assistant message, so
`id`/`status` there refer to nothing and cost bytes on every stateless replay.
The vendor table decides it, like every other wire difference.
readStream came apart into stream.go: a turn accumulator with handlers by
concern, which is what took the file back under its budget rather than the
baseline being widened.
Cache-impact: low - the system prompt prefix is byte-identical; DeepSeek
Responses sessions shift once as historical reasoning items lose id/status,
then stay shorter and stable.
Cache-guard: go test ./internal/provider/responses/ -run 'ReasoningInputIdentity|ConversationDigest'
Documentation-impact: none - docs/*.md describe neither the stream reader nor
the vendor capability table.
The settings pane listed a server's name, transport and source, and folded a
column of bare tool names underneath. Nothing on the row could answer the
question the row exists for — keep this or not — while the skills beside it
have carried a description all along. The data was already there: /mcp prints
every tool's description, and the desktop DTO dropped it at the wire.
Three gaps, one subject:
- The handshake's instructions field, the only place the protocol lets a server
describe itself, was parsed and discarded. It is now kept on the client,
carried on ServerStatus, and persisted in the schema cache, so a server that
is off can still say what it is for.
- The tool list reaching the pane is now the tool as its server describes it:
description, the read-only and destructive hints, and the schema error that
makes a listed tool uncallable.
- A server that is not connected — switched off, lazy, or failed — answered
with nothing at all, though the last handshake wrote its whole surface to the
schema cache the capability router already reads. Those rows now answer from
it, marked as remembered rather than live, and stale when the declaration has
changed since.
The lane the identity of a server travels on was spelled twice, so
mcpIdentitySpec now decides it once and Controller.mcpSpec adds this session's
timeouts on top: a project the session is not pointed at reaches the same cache
key. Server-written text is sanitized and bounded once, in textutil, because it
now lands in a browser row as well as a terminal.
Cache-impact: none - the provider-visible prefix and tool schemas are untouched; every new field feeds status surfaces only
Cache-guard: internal/serve/catalog_test.go TestMcpRowCarriesWhatTheServerSaidAboutItself pins the wire shape; no tool schema or prompt text is read or written
Documentation-impact: none - the settings pane and /mcp gain detail on rows the docs describe by purpose, not by field
Both serve fixtures built their pile by driving the old fan-out — one writer,
each conflict extending the last — which is exactly what 9ea39c24d stopped
producing: a branch is now taken over whenever it holds an ancestor of the
save, so those conflicts all land in one file. The sweep then had a single
branch and the session was sitting on it; the sidebar had a single copy and
nothing to fold.
Stage what a writer-keyed lane still leaves instead. A save that would not keep
every turn already in the lane cannot take it over, so transcripts that diverge
at the same index get files of their own: the sweep writes the fork the session
is still on first, and the sidebar's three panes each carry the conversation
somewhere else. No assertion changed — only the way the pile gets there.
The comment on siblingRecoveryBranchWithDigest still described the retired
behaviour, so it now says which cases put the same turns in two files.
Documentation-impact: none - a test fixture and a comment; no surface changed
A conflict that could not be rewritten forked a recovery branch, the
controller committed to it, and the next mid-turn autosave forked again from
there: one file every 30 seconds for as long as the turn ran. A field report
carried 30 of them from a single 25-minute turn, each one a sidebar row.
Two identities decided where a conflict lands, and both were instance state.
The isolated lane was a token minted per live Session, so a resume, a runtime
rebuild, or a reopened pane — exactly the moments a conflict recurs — started
a lane of its own; fixedWriterRecoverySessionPath already keyed the lane to
the writer, but nothing outside its own test called it. Reuse of that lane
then asked whether the bytes on disk were the ones this Session last wrote,
which a Session that had just been rebuilt can never answer, so every tick
rotated the lane and allocated another file.
Both are now semantic: the lane is the writer's, and a branch may be taken
over exactly when what it holds is an ancestor of the save — the rewrite
loses nothing, whoever wrote it. Session.recoveryLane survives as the
override allocated only when the writer's lane holds a transcript this
session would not preserve.
The lineage GC fixture built its chain by driving the fan-out, so it staged
the pile explicitly instead: what older builds left on disk still has to be
reclaimable.
Cache-impact: none - session persistence only; no provider request or prompt prefix is touched
Cache-guard: internal/agent/save_recovery_fanout_test.go asserts one file across eight conflict ticks
Documentation-impact: none - no user-visible surface changed; the fan-out was never documented behaviour
Selecting /effort on a kind="anthropic" relay wrote thinking="adaptive" into
the user's config, so the next request carried thinking.type=adaptive with
display=summarized, output_config.effort, and a 64K output budget. Those are
Anthropic's own fields; a relay that never implemented them answers 5xx, and
the persisted mode kept it failing after the level was cleared.
Depth is now a declared contract, not an inference from Kind: first-party
api.anthropic.com, an explicit reasoning_protocol="anthropic", a declared
supported_efforts depth vocabulary, or the preset_id an installed curated
entry records. Everything else exposes the binary auto|enabled|disabled menu
and receives thinking.type alone. A level persisted outside the resolved menu
goes dormant the way a Kimi K3 protocol switch already retires one, and an
adaptive mode nothing declared falls back to the provider default -- so an
already-broken config heals without a migration.
The frontends stop writing provider knobs: cli and serve no longer set the
thinking mode as a side effect of an effort edit, and the resolution moved
into the provider, which is the only layer that knows the wire. Probe now
carries the base URL into the entry it reads capabilities from, so what the
setup panel offers is what the runtime will send. GLM, LongCat, and the
undeclared-gateway menus collapse onto one binary-thinking helper.
Cache-impact: none - provider request shaping only; the system-prompt prefix is byte-identical
Cache-guard: internal/boot/anthropic_contract_test.go asserts the request body through boot.NewProvider
Documentation-impact: updated - docs/REASONING_PROVIDERS.md and its zh-CN twin gained the Anthropic-contract section
A hook that tests an unset variable is not merely broken: the expansion is
empty, the test around it silently succeeds, and a guard written to block a tool
call passes every call instead. Nothing in the transcript says so.
Doctor now names Reasonix-namespaced variables a hook reads but will never be
given, and points at where the payload actually arrives. The references come
from the shell AST, so a $NAME inside single quotes stays the literal it is.
The plugin hook environment moves to one definition shared by the injection and
the check, so the two cannot drift.
PreToolUse runs before every tool call, so a hook broken on this host filed an
identical notice on each one for the rest of the session. The second copy
carries nothing the first did not.
A hook now surfaces a message only when it differs from the one it last
reported, keyed by hook so the record is bounded by how many are configured
rather than by how often they run. Blocks always surface — the message is how
the user learns why a turn stopped — and editing hooks clears the record, since
a message suppressed against the old configuration says something new about the
new one.
A settings hook names no interpreter, so the Windows spawn path matched it
against a handful of known shapes — a batch file, an explicit `sh -c`, a .sh
script — and handed everything else to cmd.exe. A hook built from a herestring
and a pipeline is none of those shapes, so it arrived at an interpreter with no
single-quote quoting, no $ expansion and no here-documents, and failed on the
first word it did not recognise.
Whether a command needs a POSIX shell is now read off its AST rather than its
shape: single-quote quoting, $ expansion, command substitution, here-documents.
What cmd.exe does share — && chains, pipes, double quotes, plain redirects — is
absent from that list, so a batch-style hook keeps the interpreter it has had.
The same predicate answers CheckRuntime, so a host without bash is reported by
doctor and named at spawn time, instead of surfacing as cmd.exe's complaint
about whichever word happened to come first.
A stdio MCP child can exit long after a healthy handshake — a crash, an OOM
kill, a database driver aborting. The transport latched that read error for
good and the Host kept handing out the dead connection, so every later call
repeated the same EOF with the stderr tail from startup attached. That reads
like a server that never started, and only restarting the session cleared it.
The transport now marks a connection that ended before the request was written,
and a reconnecting wrapper dials a replacement behind the same handle. It is
serverProxy's trade one layer down: a stable handle, a rolling backend. A death
mid-request stays unmarked, because the server may have run the call already.
Concurrent callers share one dial, a replacement re-clears the launcher lock and
project launch grant, and live progress tokens move to the new connection.
The client's RPC and session block moves to client_session.go so every dispatch
can name the connection it targets — a replacement has to complete its own
handshake before it is published, or it recurses into the reconnect.
The previous commit hung the hint on UseCapabilityTool.Execute, which a
capability call never reaches: resolution hands the target back to the agent,
which runs it through finishToolExecution. The hint was dead code, and a
delegation run confirmed it — the rejection still read `unknown field
"items"` and the model still spent its round trips on inspect and the docs.
Moving it to the common execution path also makes it uniform: every tool now
answers a contract violation with the contract, not just capabilities. It
lands after the blocked check so a refusal does not collect a parameter list
it has no use for.
finishToolExecution was 118 lines and this pushed it past the 120-line limit,
so the hook notification it ended with moves to tool_receipts.go beside the
other post-execution bookkeeping.
Verified against a live provider: a docs call missing its operation now reads
`operation is required; it requires "operation"; it accepts "audience",
"language", "limit", "operation", "path", "query", "section_id"`.
A capability's parameters are not in the system prompt the way a built-in
tool's are, so the model learns them by being wrong. One observed delegation
run called fleet with "items", was told only `unknown field "items"`, and
spent five round trips finding the name "tasks": an inspect, a docs call that
was itself rejected for a missing "operation", then a search and a read.
The failure now names what the schema says — the parameters that are not in
it, the required ones that are absent, and the full accepted set. It reads
the capability's own schema rather than the error text, and stays silent when
the arguments fit, so a failure the capability reported for its own reasons
does not collect an irrelevant parameter list.
Booking the failure moves to usecapability_hint.go with it: usecapability.go
is 877 lines over the file ceiling, and a change may not widen that baseline.
Three leading-directive tables were the only live entrance to the two-model
planner, and they matched a prefix with no word boundary and no idea what the
sentence was about. Probed on nine requests, six misrouted: "make a plan.md
file", "make a plan_test.go that covers the contract", "give me a plan.json
schema" and "先出方案文档提交到 docs/" all asked for a file to be written, and
"plan first-class support for windows paths" matched "plan first" outright.
Each one spent a planner round on work the executor was being asked to do.
The entrance is now host syntax, the way plan mode already works:
PlannerRouteMarker rides at the front of the turn, routes to plan_and_execute,
and is stripped before the model sees it. A frontend prepends it when the user
asks for the workflow; e2ebench's -force-planner uses it instead of putting an
English sentence in front of every benchmark prompt.
Verified against the real provider with planner_model configured: the marker
yields planner 6 / executor 6 usage calls on a task that runs executor 4 alone
without it. normalizePlannerText, hasLeadingDirective, plannerDirectiveText and
its quote scanner leave with the tables — 117 lines.
explicitSkill matched six prose forms in two languages beside the host's own
/name syntax, every one of them demanding "use <name> skill" with no article.
Probed: "use the review skill on this diff" — how anyone writes it — did not
match, so the prose arms caught nothing they were added for.
explicitMCP was worse than useless. It matched "<server> mcp" anywhere in the
message, so "don't use the github mcp server" and "别用 github mcp" both
returned prefer for the server the user had just declined. Naming the tool now
means naming the identifier the host minted, mcp__<server>__<tool>.
Nothing is lost by this. routeEntry's own comment already said a capability
nobody named and no trigger matched is left to the model, and SemanticRouter
does exactly that whenever deterministic routing finds no require/prefer hit.
Author-declared triggers and negative triggers are untouched: those are the
capability's own contract, not the host guessing.
The two comment-prefix turn tests asserted the runner saw the input byte for
byte, which a transient block ahead of it breaks. They pin the turn and the
text now, not the absence of a prefix.
The previous rule was two constants and a tiebreak — Han >= 4, or Han >= 2 plus
CJK punctuation or an opening Han character. Nothing said why 4, and the
tiebreak was still an inference about a request rather than a reading of it.
It now weighs the two scripts on the prose that is left after code tokens are
set aside. Identifiers, paths and filenames carry no language: a Chinese
request that names parser.go is still Chinese, and that embedded English is
exactly what the old thresholds were fighting. Their shapes are structural — a
path separator, a dotted or underscored name, an internal capital — so no list
of extensions or keywords decides which token is code. Han characters are then
compared against Latin words, not letters, because one Han character carries
about what one word does; comparing letters would call every Chinese request
that names an English symbol English.
On 22 cases, including three that ran against the real provider, it decides all
of them correctly, where the retired cue list missed five of ten.
Measured first that the host has to decide at all: with the injected block
removed and only the standing "let this also guide the language you think in"
policy left, the model reasoned in English on all three Chinese prompts — 2%,
0% and 0% Han. With the block it is 40%, 64% and 51%, unchanged by this rewrite.
chineseReasoningLanguageCues held 30 common Chinese words, and most of them
were request verbs — 帮我, 看看, 修复, 实现, 优化, 排查, 处理, 继续. That is not
language detection, it is guessing that a sentence is a Chinese request, and it
fired on English ones that merely named a term: "grep for 问题 in the logs",
"rename 代码 to code" and "Add a 中文 test" all switched the visible reasoning to
Chinese, because the quoted term is exactly the kind of word such a list holds.
The band it guards is narrow — two or three Han characters with no CJK
punctuation; above it the script count already decides. In that band what
separates the two cases is which script opens the request, which is an
observation about writing systems rather than about what the user wants. On the
same ten cases it misfires once instead of five times, and the one it still
misses (one Han character) is below the threshold either way.
This stays an inference, not a structural fact: the guess-free path is the
explicit reasoning_language setting, which already outranks auto. Getting it
wrong costs the language of visible thinking and nothing else.
highRiskToolHints matched four substrings anywhere in a tool name, so
plugin_lint and list_plugins were privileged mutation surfaces while the real
plugin tools they were meant to catch already arrive under the namespace the
host mints for them, mcp__plugin_<pkg>_<server>__. The "plugin" fragment
caught nothing the mcp__ prefix did not, and cost false positives.
Now it is the prefix the host itself creates plus two exact built-in names.
Four free-text tables decided plan-only and plan-for-approval by scanning the
whole message for words in two languages, with a suffix-based negation check
bolted on. Probed against requests where planning is the subject rather than
the instruction, three in ten misfired: "add a test for the plan contract",
"document why we do not implement the plan cache" and a Chinese request whose
first word is 实现 all routed to plan-only. plan-only persists a no-op and ends
the turn, so each of those is work silently not done.
Both routes already had a structured source. plan-only has explicit plan mode
and a leading directive the user typed; plan-for-approval has the planner's own
structured exit, plan.RequiresApproval, set after it read the request —
coordinator.go has honored that for every planner turn all along. The tables
were a second, unreliable entrance to states the host could already reach.
So the body scan retires. A leading directive still routes a stated "give me a
plan" (the Chinese "给我方案" was missing its English counterpart's entry and is
added), and whether that plan stops for approval is the contract's answer, not
a phrase match. containsAnyLexical, containsLexicalTerm, containsNonASCII and
plannerApprovalNegated leave with their last callers.
highRiskPathHints substring-matched 35 English words against every mutated
path, and High risk forces a review plus a security_review subagent before a
turn can end. Measured against this repository: 326 of 1,314 non-test Go files
scored High, 72 of them on a spelling accident alone — phasetrace.go matched
"race", conclude_blocked.go matched "lock", meterconfig.go matched "config",
and every file under sandbox/ matched "db" through san-db-ox. A table that
cannot tell internal/auth from session_write_authority.go was deciding when to
spend two subagent runs.
Sensitivity is not readable from a path, so the host stops guessing and the
project declares it, through the mechanism already there for host checks:
`- sensitive: <glob>` bullets in the same "Reasonix host checks" section,
matched with the shared doublestar semantics in fileutil. Undeclared paths are
ordinary production code, which still demands a structured review or
host-proven verification plus diff inspection. The structural triggers are
untouched: an opaque write the host proved but cannot name a path for, ten or
more paths at once, and privileged tool surfaces all still score High.
This repository now declares its own nine boundaries, so its gate holds where
it matters and stops firing on trace files: 78 files score High instead of 326.
Nothing had ever A/B'd the effort level, and high was the shipped default.
Across 81 paired task-runs on three corpora it buys no measurable accuracy:
73/81 solved at high against 74/81 at low, while low finished faster on
66/81 (p=4e-9) and cost less on 68/81 (p=2e-10) — roughly 20% cheaper and
20-36% faster in aggregate.
The strata matter more than the total. Two runs of the e2e suite agree
(22/23 both, 18/23 and 19/23 sign tests each time). verification-stress is
not saturated at 15/20 solved, so an accuracy gain had room to appear there,
and both arms solved exactly 15. The hardest mode available, -anchor wrong,
also failed to favour high: low solved 15/15 against high's 14/15, and
high's one loss was accepting the planted wrong hypothesis in three rounds.
Not established: real-repo long-horizon work. SWE-bench Verified is the
discriminating test and does not run on this machine (no Docker, x86 images).
deepseek-pro is unchanged — it exposes no low level. /effort and --effort
still override per session.
`reasonix run --auto` refused inline interpreter code, command substitution
and here-doc-fed interpreters, because static analysis cannot read what they
would run. Unattended there is nobody the refusal defers to, and it stopped
nothing: on 16 of 17 refusals across the e2e suite the same code ran anyway
a round later, 15 of them through the write-a-file-and-run-it path the
refusal message itself prescribes. The gate only bought a round trip, and it
bought a lot of them — 17 of 205 rounds, 8.3% of the run.
Flipping it (measured with the equivalent config flag, three paired arms):
rounds -22 to -31%, prompt tokens -23%, tool failures -61%, solve rate
unchanged at 23/23. Scoped to the headless auto gate, which only
`reasonix run` builds; desktop and serve use the interactive one. The waiver
covers the shape-based human requirement alone — deny rules, explicit ask
rules and the sandbox boundary are untouched, and ask/dontAsk still fail
closed, all pinned by tests.
Both were absent from the read-only tables, so `gofmt -l .` and `env | grep X`
counted as writes and auto mode blocked them. They belong there under the rule
the tables already use for find, sort and go env: the program can read, and the
arguments decide whether this call does. `gofmt -w` rewrites in place and env
running a program can no more vouch for it than a shell can, so both stay out.
gofmt's absence had a cost on record. Three evidence tests used `gofmt -l .` as
their example of a command the host cannot prove read-only, and one carries the
incident that motivated naming the segment in a block message: "One observed
delivery run was refused three times running by the unnamed version: it rewrote
the command, moved to '&&', then to ';', and every refusal read identically."
The refusals were the symptom; the missing table entry was the cause. Their
examples move to sed, which the tables exclude on purpose because it writes
through a script language nothing here parses.
Answering "is it worse than 1.0" means running one harness against two
binaries, and everything that makes the two binaries different also makes
them read their configuration differently. Each difference produces a
quietly different experiment rather than an error, which is the expensive
kind: v1.0.0 has no --auto, ignores REASONIX_HOME, reads its key from the
process environment, and resolves a bare provider name against whatever
config file its own version understands.
The script asserts what it cannot control. Both arms run one smoke command
first and must report the same currency — the run's own evidence about which
provider it reached — normalised because ¥ and CNY are one currency spelled
by two versions. The smoke runs from a scratch directory, since a working
directory pulls .env files and convention dirs into resolution and the repo
root offered the two arms different provider sets.
CompoundLeafCommands only marked a statement compound for the chaining
operators and the control structures. A plain `a; b` therefore fell between
the two classifiers — the single-command one refuses it for containing shell
syntax, and this one refused it for not being compound — so `echo hi; pwd`
counted as a write and auto mode blocked it.
That is the same gap this function's own comment records having closed for
pipelines: "Without this it fell between the two and every `… | head`
counted as a write." Semicolons were left on the other side of it.
Measured on the 24-task e2e subset: bash calls blocked by permission policy
dropped from 7 to 3 across the three worst tasks, and their tokens per solve
fell 42%. Leaves are still classified one by one, so `ls; rm -rf /`,
`ls > out.txt; pwd` and `pwd; python3 -c ...` stay blocked.
verification-stress ships 20 graded tasks and is run by the same suite
runner, but TestSolvableCorpusSeedsMustNotGradeClean only ever loaded
benchmarks/e2e. A grader there that passes on the pristine seed scores the
same whether the agent solved the task or never started, and reports 100%
forever with nothing to catch it.
All 20 seeds fail today, so this locks in a property the corpus already has.
Checked by replacing one grader with `exit 0`: the guard fails that task.
Saying only "unreported" leaves the effort ladder unmeasurable on the
default provider entry, and effort is the largest single lever the digest
can see. The host receives the thinking text either way, so the digest now
reports the characters it actually got.
Across three real arms of the same 23 tasks it separates them cleanly:
high 140,692 chars with slow rounds at 44% of model time, low 47,317 at
13%, disabled a true 0 tok at 12%.
DeepSeek's Anthropic-compatible endpoint folds thinking into output_tokens
and reports no reasoning count; its OpenAI endpoint reports
completion_tokens_details.reasoning_tokens for the same model. The default
provider entry is the Anthropic one, so the Cognition line read "reasoning
0 tok" and "slow rounds ... 0 reasoning tok" on runs whose trajectories are
full of streamed thinking — asserting a measurement nobody took, on the
39% of model time those rounds account for.
The trajectory already carries the second signal: reasoning events. Thinking
that streamed with no count is missing, not zero, and the line now says so.
A call the host stopped before launch carries errored=true, so it fell past
the mutation branch, was not bookkeeping, and was not a duplicate — which
left it in evidence_gain, a productive outcome. Round efficiency therefore
read 99% useful on a run where 8% of rounds were permission refusals, and
the largest single waste source in the suite stayed invisible.
Re-rendering the same 82 rounds: useful 81/82 (99%) with 1.6s wasted
becomes useful 71/82 (87%) with 21.6s, of which refused x10 is 20.0s.
The work-practice prompt and every headless bash refusal tell the model to
keep scratch under $TMPDIR. The file writers do not expand it, so
write_file({"path": "$TMPDIR/check.py"}) created a literal "$TMPDIR"
directory inside the workspace and reported success — the opposite of what
the caller was told to do. Observed on 5 of 23 e2e tasks; each one then
spent three to five rounds discovering the junk and moving it out.
resolveSessionTemp substitutes only a leading segment, and only the exact
spellings sandbox.SessionTempEnvKeys exports to bash, so this closes a
contract the host itself opened rather than adding a shell expander. The
generation is created lazily by whoever needs it first, usually bash, so a
writer that names the directory acquires it too.
VERSION is the tag with only "studio-" removed, so it keeps the v — the
lookup asked for release-notes/studio/v2.0.0.md while the file that exists
is 2.0.0.md. 2.0.0 published with the standing installation text alone and
none of the notes written for it.
The dry run that was supposed to catch this set VERSION=2.0.0 by hand
instead of taking the value resolve produces, so it exercised a path the
release never takes.
The lookup now strips the v, which keeps notes files named by their semver.
The Windows build failed again after the payload moved out of /tmp. The path
makensis printed was a clean D:/a/... one and the file it named was there —
curl had written it and the non-empty check had passed — yet File still
reported "no files found".
That is the message File prints when its argument matched nothing as a
pattern. It splits directories on backslashes, so a bare forward-slash path
is one long filename to it. MUI_ICON composes "${PAYLOAD}\appicon.ico" and
compiles earlier in the same script without complaint; WEBVIEW2 was the only
member handed over as a whole path.
WEBVIEW2 is now a flag and File composes the path the way the binary, the
icon and the SPA tree already do. Packaged locally with makensis 3.12.
The Windows build failed at the WebView2 bootstrapper: curl wrote it into the
mktemp directory and the check for a non-empty file passed, so -DWEBVIEW2 was
defined, but makensis reported "no files found" for it.
Both are true at once because only curl is MSYS-aware. /tmp maps through the
user profile, and converting it for a native program yields an 8.3 short path
(C:/Users/RUNNER~1/...) that makensis cannot open — while $ROOT in the same
command line converts to a plain D:/a/... path and works. The payload now
lives under the repo, where that conversion has already proven itself.
CI never covered this: Windows built with --shell-only, and the installer had
only ever been packaged by makensis on macOS.
acquireServeLock failed with "create serve lock: file exists" whenever the
owner released the lock between a waiter's failed mkdir and the stat that
follows it. The stat then finds nothing, and the code read a missing
directory as a reason to fail rather than as the lock having just come free.
That line is the only source of the message and LockDir is created by mkdir
alone, so it cannot have been "not a directory": the ubuntu CI failure of
TestEnsureServeSerializesConcurrentClients has no other path to it. The
window is narrow enough that 200 local runs under -race did not reproduce it.
A stat that finds nothing now falls through to the same poll every other
contender already takes.
The release body was one fixed template, so 2.0.0 would have published a
first release that said nothing about what it is. A version's notes now live
in release-notes/studio/<version>.md and the workflow appends the standing
text about signing, installation and self-update to them.
Publishing without that file still works — it warns and carries the standing
text alone — because a missing note is not a reason to fail a build that is
already signed and verified.
2.0.0's notes are this line's first, so they read as an introduction rather
than a diff: what the workspace does, how models and accounts are named, what
extensions may redraw, and the three limits that outlive the release.
Four descriptions had drifted from the code that overtook them, and the
release notes are the ones users read:
- the GitHub release said Windows and macOS were both unsigned and that
self-update was unavailable, while the macOS job now fails closed without
a Developer ID and all three platforms update themselves;
- studio-manifest's package comment said platforms stays empty, which is
what turns self-update off, while run() has been filling it;
- studio-build.sh said the Windows artifact is a portable archive because
there is no NSIS installer, which the script itself now builds;
- STUDIO_RELEASE.md carried a whole "Self-update is not available yet"
section and listed the missing installer as a known gap.
Windows staying unsigned is the one claim that survived, so it is still
stated — SignPath allows one origin and this branch is not it.
Library validation was left enabled, which neither codesign nor notarization
reports — it surfaces on a real Mac at launch, and this line had never produced
a signed build to find out on. The desktop line's set is the only one in this
repository a signed Wails build has ever launched under, so the first signed
Studio release uses it rather than an untested tightening.
studio-build.sh signs with a Developer ID when the keychain holds one and
ad-hoc signs when it does not, and the workflow never staged one — so every
macOS artifact this line could have published was ad-hoc signed and
un-notarized. Studio declares SelfUpdate: true, which promises a replacement
bundle Gatekeeper still opens, so the gap would have surfaced as a broken
update rather than a refused first launch.
The desktop line's own step, unchanged: one Developer ID signs any bundle
identifier its team owns, and all five APPLE_* secrets are repository-level,
so the build job reads them without an environment. Official macOS builds now
fail closed the way the desktop line's Authenticode gate does.
node:fs typechecks only where @types/node is installed, and the frontend does
not install it — the gate passed locally on a stale node_modules and failed the
moment CI resolved the lockfile from scratch. import.meta.glob reads the same
files with types the project already has.
The named steps stopped at 1.3, which is a 1080p answer: on a 2560 display it
leaves the transcript around 150 characters to the line, and there is no step
anyone could have named in advance because what a 2560 display wants a 3840
one does not. The range takes over past the names rather than the list
growing a tail of numbers, and it reaches 2.5 safely only because the layout
now folds on the room it actually has.
Not doing: capping the column width. tokens.css records that a 900px --doc
was tried and taken out because it hung the flow in the middle of a wide
window, and the 68ch measure was refused for the same reason. Raising the
scale shortens the line by itself, since the columns beside it are fixed.
A media query answers for the real viewport, and the zoom setting does not
move it — at 1.3 the interface is a third larger while the layout still
believes it has the whole screen, so the columns never give way when they
have run out of room. Measured: innerWidth reads 1920 at every zoom, and the
1200px query returns the same answer at all four steps.
document.body is already laid out in the scaled space, so its content box is
the viewport divided by the zoom with no arithmetic anywhere: 2133 at 0.9,
1477 at 1.3, 960 at 2.0, exact at each. viewport.ts reads that and publishes
which columns have folded; the stylesheet names the fold and never the
number. Two things move it, a resize and the zoom setting, and each calls the
one derivation rather than keeping a copy of the thresholds.
Container queries would say this in CSS alone and are the better answer once
Safari 15.6 is no longer a target — it still is, which is also why there is
no nesting here.
The vh compensations come with it: those lengths measure the unscaled
viewport, so the model picker's cap rendered 1150px tall on an 855px screen
at the ceiling this makes reachable, with its tail past the edge.
Seventeen keys the interface asks for were never in the catalogue, so scope
and server-onboarding rendered Chinese to an English reader. The catalogue's
own header says a test is what keeps it from staying incomplete quietly —
that test did not exist. It does now: it reads every t("…") in the source and
fails naming the key and the file it came from.
It initialised an STA apartment and then let the goroutine migrate, so under
load the WebView2 environment was created on a thread that had never called
CoInitializeEx — the CI-only "CoInitialize has not been called". The package's
own init() already locks its thread before initialising COM; the test now does
the same. Its two subtests become plain closures for the same reason: t.Run
would run them on their own goroutines, and a COM object answers only to the
thread that made it.
"echo ok | sh -c 'exit 4'" asserts PIPESTATUS is [0 4], but the right side
exits without reading: when the machine is loaded enough for it to win, the
echo takes SIGPIPE and reports 141. Measured both ways locally — a left side
that writes late reports 141 every time, one that never writes reports 0. The
case is about the last command failing while the first succeeds, so it uses a
left side that does not write.
dialAgent's Windows build only ever returns an error, so the shared callback
in auth.go held a branch that could never be taken — staticcheck says the
comparison is always true, and it was right. The platform split now sits on
agentAuth itself, which is what the Windows comment already claimed, and the
IdentitiesOnly filtering that exists only to serve it moves with it.
Several input methods end the composition just before the confirming Enter
arrives, which is what the grace window in useIme exists for. But the
composer only returned early on it — it never stopped the event, so the
textarea did what it does with an unhandled Enter and inserted a newline.
Finish a word, press Enter, and the first press broke the line while the
second one sent. Measured on the running composer: that Enter now reports
defaultPrevented and leaves the text alone, and the next one sends.
Every turn on the timeline is the same shape, so your own message was told
apart from the agent's by a 20px inverted square in the gutter — a screen of
cards later, you cannot find where you spoke. It now carries a filled block
and a left rail, in neutral --text rather than a hue: every hue in this
system already means something (net/deleg/warn/err) and borrowing one would
lie. Newlines survive too, because the shape you typed is half of how you
recognise it.
The window had no copy affordance at all — the system context menu was the
only way to take an answer out of it — so the button under the body is
present rather than revealed on hover, and it appears only once the answer
is whole. navigator.clipboard is undefined where Wails serves over its own
scheme, hence the fallback.
Also routes the thinking label through t(): the catalogue has carried a
translation for it the whole time and the call site was passing the Chinese
string straight through.
The lint job runs repo standards before golangci-lint, so while the former
failed the latter never got to speak. reflect.TypeFor, slices.Backward,
WaitGroup.Go and t.Context, applied by the analyzers themselves.
Splitting rebuildWith out gave every caller an explicit adopt flag, and the
one-line wrapper that used to be the entry point kept compiling with nobody
calling it. rebuildOptions still has its other readers.
The test drives bash to park its output, then follows the pointer. On a
host with no OS sandbox the enforced bash tool refuses fail-closed, so
there is no pointer and the second turn never happens — the failure reads
as "got 1 tool result", naming nothing about the sandbox. CI's coverage
job never installs bubblewrap and had been passing on whichever runners
happened to ship it. The subject here is the pointer, not the jail.
run had grown past the function-size limit carrying a twenty-line asset
middleware inline; it is one decision — hub, or assets — so it reads as a
function. The same edit that grew run also inserted windowNotifications
between grantWindowCapabilities and its doc, leaving four lines about
folder pickers and provider keys sitting above a notification sink.
VersionedInstaller grew a Line field — the host's declaration of what a
release carries — and the installer reads it to know which members to
extract. The linux test still built the installer without one, so both
cases failed at "release unit has no members" before reaching what they
were written to check.
Five files each carried their own k/M rule with different thresholds and
decimal places, four spelled a duration to four different precisions, two
converted bytes, and money was a symbol table glued to toFixed(2). The
English window had no thousands separator anywhere, because every large
number reached the screen by interpolating the raw value.
They now go through one module built on Intl. The kernel already sends
the ISO currency code and says it is preferred over the symbol — nothing
read it, so an English reader saw ¥ where CN¥ was meant, and no formatter
could place the symbol where a language wants it. Percentages take a
ratio and let Intl put the sign; durations and byte sizes state their
precision at the call site instead of each inventing one.
What deliberately does not go through it: SVG path coordinates, the
trajectory export's rounded values, and aria-valuenow. Those are machine
inputs, and a thousands separator in a path attribute draws nothing.
The technical suffixes stay untranslated for the same reason. Intl's
compact notation renders 12345 as 1.2万 in Chinese, which is a quantity
feeling rather than the scale a token count is read on — k, M, KB and s
mean the same thing to both readers, so Intl formats the number and the
domain keeps the unit.
SayCard was building its label by string concatenation and never called
t(), so an English window read it in Chinese. The catalogue already had
the entries; only the call site was missing.
The "notify me when it finishes" recipe was an osascript line, so on
Windows and Linux it was a suggestion that fails the moment it fires.
A starting point that cannot start is worse than one fewer.
The kernel will not pull a workspace out from under a pane that is still
writing, so removing a folder with tabs open just failed — and the
refusal named no pane, leaving the reader to work out which of eight tabs
belonged to that folder. Removal now closes the folder's own panes first,
the way dropping a session already did, and waits for them: the runtime
holds the transcript's lease until it is down.
onClose takes a set rather than one id, since the answer is "these", and
liveIds is asked only while the confirmation is on screen — run state
changes constantly and walking every runtime to render a row is not worth
it. busy() carries params now, so workspace.has_open_panes can say how
many there are; a refusal that says "close the pane first" is only
useful next to which one.
A new source had to be named by hand before it could be saved, and two
accounts on one host both ended up displayed by that host — which says
nothing about which is which. The name is now derived from the host
(derivedName) and prefilled, so nobody has to invent one, and it comes
from a single derivation so "is this still the name we generated" stays
answerable later.
That question is what the picker needs. modelEntry carries Preset, which
marks a name we shipped rather than one somebody chose, so accountLabel
can tell a curated entry and our own -2/-3 suffix from a name typed on
purpose; only when no entry has one does the shared host speak for the
account.
An extension author who edited their runtime's code had to restart the
app to load it. Reloading was already wired — CLI, serve and ACP all
expose it — but it rebuilt through the same options a model or workspace
switch uses, and those deliberately carry the serving generation forward:
the sidecars keep running, the dependency graph is not re-walked, and
skill/command/hook discovery is reused. That is right for a switch, where
the extensions did not move. A reload happens because they did, so
reusing either handed the old code straight back.
Reload now builds its own options: no sidecar manager, no reused
assembly, no previous plan, snapshot or graph. The runtime owner stays,
because it identifies the session lineage rather than the extension
state. Since the replacement now starts its own sidecars and the old
manager is closed right after the swap, the reload also records the new
generation as the base for later reuse — without that, the next switch
would reuse a manager that no longer exists.
Studio had no way to ask for it at all: no port method, no control, only
a stray busy.reload_extensions string left over from the old frontend.
The extensions pane gets a Runtime group above the package list, since
what it reloads is the whole runtime and not one package. The control
carries its own duration — a breathing dot while sidecars restart, a
settle when it lands, a nudge and the kernel's own reason when it is
refused mid-turn — reusing the motion and colour vocabulary already in
the sheet rather than introducing a spinner this interface does not have.
sse.ts and Settings.tsx were both at the file ceiling, so the transport
half of the port moves to sse_http.ts (mirroring how the fixture is
already split) and the reload control to its own hook.
An oversize tool result was snipped head+tail with the middle discarded,
even when the tool that produced it could simply be read on from where it
stopped. read_file numbers every line it returns and names the offset to
continue from; read_subagent_result pages by byte offset. Cutting the
middle out of either undid the paging the tool had just done correctly,
and left the model re-reading args it had already narrowed.
Tools now declare whether they address their own continuation
(tool.Paged). An oversize result from one is cut back to whole leading
lines with a marker saying to read on — nothing is discarded, so it
carries no truncation notice. Everything else still spills to a file and
only truncates when there is nowhere to write.
Two judgements that read wording are gone with it. The limiter picked its
head/tail geometry by matching the tool's name, duplicating the SnipHint
contract those same tools already implement and mis-serving every MCP
tool whose name happened to contain "read"; it now asks snipStrategyFor.
Failure was detected by searching the body for "error:" — which misses
`--- FAIL` and every non-English toolchain, and fires on prose that
mentions the word. The caller knows; it passes the fact.
Frontends could not tell a result that moved to disk from one that lost
its middle: both arrived as Truncated=true. event.Tool now carries an
OutputBound naming which of the four happened, with the original's size
and where the full text lives. Studio says so on the card and reserves
its warning colour for the one case where the model really did not see
the rest. Its fold is a clip against one visual budget rather than three
separate line thresholds, so the rows a grep or ls result reported are no
longer silently dropped at forty.
Users reporting one conversation appearing many times in the sidebar have to be
walked through %APPDATA%\reasonix\projects\<slug>\sessions by hand, and the
answer to "is this a recovery fork, a repeated create, or a dual writer" lives
in the .jsonl.meta sidecars nobody knows to look at.
The script collects it in one double-click: the session listing with content
hashes, the meta lineage (parent_id, recovered, recovery_reason,
recovery_depth), the conflict and lease sidecars, running Reasonix processes,
and doctor output when the CLI is on PATH. It groups the findings by identical
content, by title, by topic_id, and by zero-byte, so the three causes separate
in the report itself. Chat bodies never leave the machine; titles are truncated
and the user is told what is in the zip before sending it.
.gitattributes pins *.bat to CRLF. cmd.exe misreads an LF-only batch file and
runs past exit /b into the payload, which is what the file does on any checkout
that normalizes it — core.autocrlf hides this on Windows only.
The steer told the model to prefer grep, read_file, ls, glob, edit_file and
move_file over shell equivalents. Four of those six never reach the provider
schema: applyUnifiedProviderToolSurface narrows it to CoreProviderToolNames,
which has no grep, ls, glob or move_file — they are reachable only through
use_capability. A recommendation whose names the model cannot find discredits
the whole sentence, including the part that was true, so it reaches for the
shell instead. On Windows the same description handed it the recipe:
"Get-Content (cat)" plus "no head/tail: use Select-Object -First N" is exactly
the Get-Content | Select-Object -Skip N -First 20 paging users have reported.
Name only the three file tools that are provider-visible, drop Get-Content from
the PowerShell mapping (Select-String stays — grep really is unreachable, so
shell search is still the only way to search), and replace the abstract
"prefer the dedicated tools" with the concrete alternative it lost to: what
read_file returns per call, that the line numbers are what edit_file targets,
and what shell paging costs instead. The line count comes from
readFileDefaultLimit so the prose cannot drift from the constant.
bashSteerTools carries the names so internal/boot asserts each one against the
real provider request rather than the declared allowlist; putting "grep" back
fails it.
Live A/B, deepseek-v4-flash over a 2571-line file whose read_file output
exceeds the 32KB spill threshold, 4 runs per arm: shell paging fell from 3/4
runs to 0/4, first file action was read_file in 4/4 rather than 3/4, and mean
bash calls went 2.0 to 1.25. Below the spill threshold the old text already
behaved, which is why this only shows on large files.
Cache: ToolSchemaTokens 4236 to 4247 (+11), ToolsHash and PrefixHash rotate
once on upgrade. SystemHash is unchanged.
Close the window, reopen before the process finished, and the transcript starts
forking into an endless run of recovery copies. Three things had to line up, and
all three were real.
The window vanished on the close button while the process was still saving. That
is the app telling you it has closed, so reopening then is a reasonable thing to
do — and it is what puts two processes on one workspace.
Nothing refused the second one. Ownership of a session was arranged by whoever
happened to build the runtime: the CLI takes the lease before it builds anything
and refuses a held session there, hub.Open takes one when it is handed a path,
and hub.Adopt — the path the shell opens on — took none at all. A window
therefore never held the session it was writing.
And that is what decides the shape of a collision. A session that has bound
write authority at least once fails closed when it loses it; one that never
bound any forks a recovery copy instead (agent/session.go, authRequired). The
window's sessions never bound one, so two writers meant copies rather than a
refusal, and each copy gave the other something new to conflict with.
So: ownership becomes a property of a runtime rather than of the host that
happened to make it — Adopt arranges it exactly as Open does, and a host that
already has its own keeps it. Authority then follows the session instead of
being re-established at each entry point able to move it: it hangs off
setSessionPath, the single place every path change lands, which is what finally
covers the path no endpoint mints — the one a controller creates for itself on
the first turn, which is precisely the session a window runs on.
Being refused is not an error everywhere. A session that was named — CLI
--resume, a click in the sidebar — refuses, as /resume already did. A session
merely inherited, which is what a window opens on, is not worth refusing over:
the window takes a new one. Writing into the held file is what forks it.
The close button now starts the shutdown and keeps the window up for it. Nothing
is faster; nothing lies. Clicking again does not cut it short, because only the
quit the shutdown issues itself may take the window down.
Verified by removing it: with the setSessionPath handler disabled, a pane's own
freshly minted session is free for any other writer to take, and the test says
so. No timeout was shortened and nothing polls — a held session is refused at
the moment of adoption, which is while the caller can still choose another.
Studio saves a new key to the credential store and returns. The session
running at that moment kept sending the old one, because every provider
copied the key into itself at construction and no request ever asked again.
Swapping an exhausted key for a funded one therefore changed nothing: the
same 402 came back, from a key the user had already replaced.
A key is external mutable state and was modelled as an immutable value. The
config now carries where to get it, not what it was — the provider entry
already reads the credential store per call, so passing that method is the
whole live source. An empty answer falls back to the key the client was built
with, so a credential file that momentarily cannot be read does not break a
run that was working.
This is why the save path deliberately does not rebuild: the conversation
must not be interrupted to change a key, and now it needn't be. Config moves
to its own file, which is where its resolver belongs and what keeps
provider.go from growing.
Assigning the guardian role answered 204 and changed nothing. Config writing is
hand-rolled TOML, and the renderer had no line for guardian_model — so the API
accepted it, the file was written without error, and the next load returned the
zero it started from. The UI then drew "follows the main model", which is what
the config now actually said.
It was never only guardian. Walking AgentConfig field by field turns up eight
settings the kernel reads and the renderer cannot write: guardian_model,
guardian_temperature, triage_model, task_cost_budget, task_time_budget_minutes
and goal_token_budget are live and now render; auto_plan and its classifier are
retired and correctly do not.
The test is the part worth keeping. It reflects over every [agent] key, writes
a value, saves, loads, and demands it back — with an explicit list for the keys
the loader is supposed to drop, asserted NOT to survive so that list cannot
become somewhere to park a field the renderer merely forgot. A struct field
added without a renderer line now fails here instead of shipping as a setting
that silently does nothing.
The delegation keys move to their own file rather than growing RenderTOMLForScope,
which is already 750 lines and 155 branches. They belong together anyway: every
one of them names a model other than the main one, or bounds what those handoffs
may spend.
Phase B opens a second connection per server so a slow prompts/list cannot
queue behind a tool call — servers commonly answer one request at a time, and
that isolation is still worth having. But it handed the same timeout context
to both jobs `start` splits: the one that bounds the handshake, and the one
that owns the child. Five seconds later the child was killed regardless of
what it was doing.
A server that imports a data stack needs longer than that to reach its own
entry point, so it was killed mid-import, every time, having never run. What
the host saw was `read: EOF` from a pipe with nobody left to write it; what
the machine saw was a second and third process per server, each opening the
same database before dying. Neither looked like a timeout, which is why it
read as a server crash or a table deadlock.
The handshake keeps a budget — the server's own configured startup timeout
rather than a hardcoded five seconds — and ctx owns the child, as `start`
documents. The regression test uses a server slower to come up than the old
bound and fails against the old code with exactly the reported symptom.
Three times now the interesting logic on this side was verified by bundling it
out to a scratch script, reading the output, and deleting the script: the
reducer's rule for an interrupted turn, the port's recovery path, and the
stream-identity check found by running the real thing. None of it survived, so
none of it defends anything.
vitest, because vite is already the build — the config is the one it reads
anyway, and no environment is needed: both suites are pure logic over globals
they stub themselves, so there is no jsdom to carry.
What the fifteen cases cover is what a type error cannot reach. That a card
which never left its streaming placeholder is not the same as one that ran and
failed, since only one of them can have left the tree dirty. That a replay
lands in order, that frames arriving mid-replay wait for it, and that a result
therefore cannot overtake the dispatch it answers. That a gap nothing can close
is reported rather than rendered as a quiet turn. That numbering which goes
backwards is a restarted server and not a hole.
CI runs it between typecheck and build, so a break shows up before the slower
of the two.
Found by running the real thing: numbering starts over when the server process
restarts, and the client was still comparing against the watermark it held from
the process before. Every number after that is lower than what it has seen, so
the gap check can never fire again — the view stops noticing losses entirely,
and nothing says so.
Numbering that goes backwards is now read as what it is: a different stream.
Inferred rather than carried as a stream id, because a resumed client is never
sent a lower number than it holds — replay counts up from where it left off —
so nothing else produces this. The client resets to the new numbering and asks
the pane to rebuild, which is the same answer it already gives to a gap it
cannot close.
The desktop shell never hit this: its server is in-process and restarts with
the page. A browser pointed at a long-lived `reasonix serve` is where it shows.
A dropped frame used to be a lost frame. The buffer was a channel with a
`default:` arm, so whether a frame survived depended on how full that channel
happened to be when it arrived — a property with nothing to do with whether
anything downstream could recover from losing it. Sixty-four frames of streamed
text were enough to cost a client the approval_request behind them, and no
later frame would ever reveal the hole.
Frames a client cannot afford to miss are numbered now, and the number is the
whole recovery model. SSE already specifies this: `id:` on a frame, the browser
replaying Last-Event-ID on reconnect, and no id at all on a frame that should
not move the resume point. Streaming deltas get none, which is exactly right —
the text after one supersedes it, and numbering them would have a reconnect
asking to be sent output it has already displayed. The desktop shell's bus has
no connection to rebuild, so it asks over /events/replay instead; both arrive
at the same log and the same numbers. A gap the log can no longer close is
stated, and the client rebuilds from /history rather than rendering a hole that
looks like a quiet turn.
The bounds are on different axes because the two classes of frame want opposite
things. A numbered frame has to arrive, so it is bounded by memory in bytes —
frames here span three orders of magnitude and a frame count would bound
nothing anyone cares about. A streaming delta has to arrive *now* or not at
all, so its bound is the live window itself: a queue standing a whole channel
deep means the client is out of step, and a delta behind that backlog would
arrive describing text already on screen. That replaces the two hand-tuned
thresholds this started with, and the watermark on the keepalive closes the
last case — a frame lost at the end of a turn, which nothing later restates.
Verified against a real DeepSeek session, not only in tests: 165 frames, 13
numbered; reconnecting at Last-Event-ID 5 returned exactly 6–15 including the
pending approval_request, and /events/replay returned the same range for the
transport that cannot reconnect. Race detector clean across the package.
Measured against the real model: a bash project whose check is ./check.sh had
its bug fixed, ran the check, watched it pass — and the run exited 1. The
classifier cannot tell a project's runner from a deploy, so it read no check,
and the turn was failed for the host's own blind spot. Anyone driving `-p` from
CI got a failure for work that was done.
Nor did the failure buy anything. The gate reads the writer from this turn, so
the next one — having written nothing — passes with no evidence at all. It
could not collect later what it refused to accept now; it only cost a turn and
a false red.
So the gap now says which kind it is. Nothing ran at all is still the turn's
own miss and still fails. A command that ran and could not be read is an
advisory: it names what went unread and how to declare it, and lets the turn
end. Delivery is untouched, and its stricter static answer still stands.
Print mode dropped every warning, having nowhere but stdout to put one, so the
advisory would have been invisible where it matters most. Warnings now go to
stderr, where the run already reports itself — stdout still carries the answer
alone, and no pipeline changes. That also restores planner fallbacks and folded
user turns to view.
Verified end to end against deepseek-v4-flash: unreadable check → exit 0 with
the warning on stderr and the fix applied; wrote a file and ran nothing → still
exit 1.
Sixty-four frames of streamed text were enough to cost a subscriber the
approval_request behind them, and the turn_done behind that. The buffer was a
plain 64-slot channel with a `default:` arm, so what a frame's survival
depended on was how full that channel happened to be when it arrived — a
property with nothing to do with whether anything downstream could recover
from losing it. A frontend that misses an approval waits on a dialog that
never opens; one that misses a turn boundary stays running forever. Both are
states nothing later restates.
The frontend event sink already knows this — it refuses to let an extension
drop ApprovalRequest/TurnDone-class events for exactly this reason — but the
broadcaster underneath it dropped them on a buffer check.
So the kind decides now, not the timing. Streaming deltas stay droppable: the
text after one supersedes it and /history has the whole thing. Everything else
queues. Frames land on a per-subscriber queue that a single pump goroutine
drains into the channel, which keeps Emit non-blocking — the property the
original design was protecting, and the one worth keeping — while making the
choice of what to lose deliberate. That pump is also the only goroutine that
sends on the channel or closes it, so a client disconnecting mid-send cannot
race a send on a closed channel.
A hard cap bounds the queue for the case where even the frames that matter are
outrunning the client. It sheds oldest-first and says so in the log once: the
newest frames are the ones carrying the state that would let the frontend stop
waiting, and until now every drop here was silent.
Tests cover the three properties: prompts survive a backlog, the survivors keep
provider order, and Emit still does not block on a client that has stopped
reading. Race detector clean across the package.
The branch added a turn earlier told the model to have someone declare the
project's checks in project memory. That is a real mechanism but the wrong
answer to this question: it is project-level setup, it needs the user, and it
does nothing for the turn already stuck. Naming the check is something the
model can do right now, and 3c3e0938f already built the path — complete_step
carries a verification citation, and the ledger corroborates that the named
command ran after the write and exited zero.
So the ask offers that instead, quoting the command that actually ran. What
the model may decide stays one thing: which command was the check. Declaring
checks stays documented as the stronger, optional form, no longer as the way
out of a turn that cannot end.
The command classifier knows a fixed set of checks and deliberately cannot
tell `python deploy.py` from `python run_tests.py`, so a project driven by
its own scripts satisfies nothing it looks for. The gate then asked for "a
relevant verification command" — to a model that had just run one, and had
no way to learn that naming the project's checks is what settles it. One
report spent 357 steps against that wall.
Widening the classifier is the wrong repair: reading a deploy as a check is
exactly what it fails closed to avoid. Instead the ask now tells its two
situations apart. A recognised check that failed already had its own
wording; a command that ran unrecognised now quotes what ran and names the
section that would make it count. That section name is exported from the
parser rather than spelled out a second time.
The declaration syntax had never been documented either, which is the other
half of why nobody found it.
Three defaults, three separate reasons the window was tiring to read.
-webkit-font-smoothing: antialiased was written for macOS, where it helps.
On WebView2 the same line turns off ClearType's subpixel rendering, and
Chinese glyphs lose the fill their strokes rely on: at 13px the page goes
soft. It is scoped to the platform it was meant for.
The soft contrast tier — the default one — put --ghost at 2.7:1 against the
card it is drawn on. Its own comment claims both ends are inside four times,
and they were, measured against --page. But ghost almost only appears inside
cards, and against --raised it sat under the 3:1 floor. Both schemes clear it
now.
13.5px is a size chosen for Latin. Chinese fits more strokes into the same em
and blurs first, so the reading tier starts a step higher when the interface
is in Chinese. The appearance panel's steps move with it, and they live next
to the default now instead of repeating it.
The kernel emits a placeholder dispatch the moment a tool call begins, so the
card is on screen while its arguments are still streaming. Interrupt a turn
inside that window — the model was writing twenty file bodies and the user
stopped waiting — and every placeholder is still running when turn_done lands.
The seal told each of them the same thing: that the step ended without
reporting a result. Twenty identical sentences, every one of them the opposite
of what happened. Nothing was dispatched, nothing ran, no file moved, and the
reason the turn actually ended scrolled off the top.
They fold into one line now, and it is the line worth reading: how many calls
never started, and that the workspace is untouched. A call that was really
dispatched and really did die without a result keeps the old wording. The
difference is the whole point — only one of the two can have left the tree
dirty.
The wire omits `partial: false`, so the full dispatch that follows carried
nothing to clear the placeholder's flag; spreading it left every executed call
marked as one that never started. Folding through a merge that normalises the
flag is what makes the two distinguishable at all.
Every transport held a lock across the whole round trip, so a second call
on the same server waited out the first — and the wait was on a plain
mutex, which takes no context. A slow tool therefore did more than delay
its neighbour: it made the neighbour unabandonable, because cancelling the
turn could not return a goroutine parked on a lock. That is the shape of a
host that sits at idle CPU going nowhere while a long screening run works.
Nothing about it was load-bearing. stdio and SSE already demux replies to
the waiting call by id, writes are already serialised on their own mutex,
and the shared state has its own lock — the round-trip lock only undid what
id demuxing is for. HTTP's lock does guard state, so it now covers the
state and not the network.
MCP's cancellation notification goes out when a call is abandoned. Without
it the server keeps working on a result nobody will read, holding whatever
that work locked, and the next call arrives to contend with its own
predecessor. initialize is exempt: the spec forbids cancelling it.
Every component test passed while the loop was running: each spill was
individually cheap and provably smaller than what it replaced, and nothing
asserted the content ever reached the model. This drives Build end to end —
read a large file, follow the pointer it returns — and checks what actually
arrives at the provider boundary, which is where the promise is kept or lost.
Every front end hand-rolled its own loop over SessionSidecarFiles, which by
construction lists only regular files, so the one sidecar that is a directory
was skipped by all of them — spilled output outlived the conversations it
belonged to, unreferenced and unreachable. Collapsing the three loops onto a
store helper removes the class of bug rather than this instance: hand-rolling
is what let each caller drop something different.
Directories earlier deletes already stranded are aged out by the reconciler
the front ends run at startup.
read_file is how a pointer gets redeemed, so sending its output through the
same gate handed back a pointer to a further file instead of the content —
and the line numbers it prefixes grow the body every round, so the loop
diverged rather than converged. One session spent 1936 reads never seeing a
byte of what it asked for. A fetch aimed at the spill directory now stays in
context; anything else still spills.
The gate also priced a read-back at one more pointer while its own comment
said a whole extra turn. Charging what the turn costs puts the bar where a
single fetch stops recovering a result whole: under it, spilling buys a
pointer and a turn to arrive exactly where leaving it would have. Everyday
bash and read_file output stops leaving context at 1KB.
With neither transcript nor archive there was nowhere to spill and the only
remaining bound was truncation, which discards 99.7% of a 5MB result. Falling
back to scratch keeps that case lossless too.
Two checks outlived what they were checking. The Scoop launch test builds
cmd/reasonix-launcher to prove a desktop install starts through it, and that
command went with the desktop line. apply_darwin.go was left unformatted by the
same change that threaded the bundle identifier through the handoff; the desktop
module's gofmt gate is what catches it, and golangci-lint alone does not.
Studio is the only shell this module builds, and it publishes through
release-studio.yml. What is removed here is the machinery of the lines that no
longer ship from this branch: the desktop build and packaging scripts, the
desktop release workflow, the stable control plane that published CLI, npm and
desktop as one approved set, and the SignPath contract that existed to bind
Windows signing to that control plane's one protected origin.
The two commands go with them rather than being kept as orphans: the launcher
survives a swap that no longer happens, and the legacy migrator moves installs
of a shell that is gone. internal/desktoplauncher had no other caller, and
ci.yml no longer names it.
Nothing here touches what still ships. cmd/reasonix and npm/ stay: the CLI is a
product, not a release line, and removing a publisher is not removing what it
published. The guards that outlived their subject go too — release-workflows.
test.sh asserted properties of workflows this commit deletes.
The bundle swap was already written and Studio's main already dispatched the
detached child that performs it. Two things kept it shut: a package-level
MacSelfUpdate that nothing set once the desktop host was retired, and a bundle
identifier hardcoded to that host's — so the swap would have refused the very
bundle it was meant to install.
Both move into the line. MacLine carries the identifier the swap checks a
downloaded bundle against, and the flag that says whether this line's releases
are signed and notarized at all; a line that ships unsigned keeps the download
page rather than writing a bundle Gatekeeper will refuse. The package-level
variable goes with them, so nothing about a product line is left as process
state one host has to remember to set.
The detached child verifies too, and it is re-executed rather than told what it
is, so the identifier travels as an argument. Reading it back off the bundle
would ask a bundle that fails verification to say what it is.
The manifest resolves the universal archive for both macOS keys — the slices
ride in one file, so a second identical download would be a release asset with
nothing to distinguish it. The disk image stays a human download: handing the
swap an image gives it something to mount, not an app to install.
Studio's Windows install is one executable beside the SPA tree it renders, and
the shared versioned path exists to swap five of them under a launcher while
keeping a directory to roll back to. Adopting it here would have meant a
launcher Studio has no use for, an update helper to outlive the process, and a
current.json layout — machinery for a problem this shell does not have.
So Windows takes the same shape Linux already does: borrow the installer instead
of reimplementing version management. The manifest resolves the installer as the
platform asset, the download path verifies it exactly as before, and the running
build starts it and exits. Going back to an older version runs an older
installer, which is why nothing here asks the direction.
The handoff has one real hazard: for a moment the old Studio still holds its own
executable open and Windows refuses to replace it. The installer waits for that
handle to clear rather than failing, and gives up after twenty seconds so a
genuinely stuck process reports an error instead of hanging.
Two things the manifest must never do, now pinned by test: resolve an archive as
a platform asset — the updater cannot place one — and resolve the .deb as one
too, because writing its files behind apt leaves dpkg and the filesystem
disagreeing.
installlayout gains ActiveMemberPath so current.json can locate a file the
caller names. Which files a version directory carries is a product line's
business, not that package's.
A zip is not an install: nothing registers it, nothing puts it in Start, and
uninstalling means remembering where it was unpacked. Studio now ships an NSIS
installer beside the portable archive, carrying the one binary and the SPA tree
it draws its UI from — the tree has to stay a sibling of the executable, because
that is where frontendAssets looks.
The desktop line's installer could not be borrowed. Its NSIS sources are Wails
build output that the repository ignores, and they describe a five-executable
payload with a versioned layout Studio does not have. The WebView2 bootstrapper
is fetched from Microsoft's evergreen URL at build time for the same reason, and
a fetch that fails drops the bundled runtime rather than failing the release.
Windows artifacts stay unsigned: the production SignPath policy admits exactly
one origin, and it is not this branch.
studio-manifest's downloads now lists what installs itself — the disk image, the
installer, the package. The archives remain release assets for whoever wants
them, but offering one beside an installer only asks the reader to choose blind.
The bundle claimed LSMinimumSystemVersion 10.13 while its binary was stamped
minos 26.0, because nothing set a deployment target and clang defaults to the
builder's own OS. Finder reads the claim and opens it; dyld reads the stamp and
refuses. A release built on a current machine therefore ran nowhere but on
another current machine.
Both slices now carry a measured floor rather than an assumed one: 10.13 is as
far back as this source links, and Apple Silicon did not exist before 11.0.
Info.plist takes the lower of the two, because that is who can open the bundle.
The target has to reach the Objective-C compiler as well — Wails' own objects
otherwise keep the builder's version and warn at every link.
The Intel slice was never a toolchain limitation. It failed because clang was
not told -arch x86_64 and produced arm64 objects, so a universal build is simply
available now.
Signing uses the Developer ID in the keychain when there is one, with a hardened
runtime and the JIT entitlement notarization's hardened runtime would otherwise
deny WebKit — a bundle signed without it renders a blank window. Notarization
follows when credentials are present, and the disk image is signed and stapled
separately: a ticket in the app does not travel on the image, and the image is
what the user downloads. With neither certificate nor credentials the build
still produces a runnable ad-hoc bundle.
Retiring the old shell took desktop/frontend/src/lib/types.ts with it, and the
guard that keeps Go's event payload and the frontend's view of it in step read
exactly that file. The contract did not disappear with the shell — frontend-next
declares the same thing in port/wire.ts, whose first line already says it mirrors
this package — so the guard reads that instead.
Pointing it there is what surfaced the drift. The new frontend never mirrored
memoryCitations, checkpointTurn or the Context* token fields, so nothing on that
side could name them; outcome was a bare string where only two values exist; and
CacheDiagnostics marked as optional five fields the wire sends unconditionally,
which asks every reader to handle an absence the producer never emits.
The assertions themselves drop the Wire prefix they inherited: the shapes are
the same, and holding a new frontend to the old one's type names would fail on
spelling rather than on coverage.
The Wails-bound app and its React frontend are gone. Studio reaches the
kernel through internal/serve's HTTP routes instead of bound Go methods,
so the shell that replaces ~320k lines is next/ plus the SPA it serves.
Three things the deleted tree owned move rather than disappear: the
WebView2 fork's patch guard, the macOS dock-icon safe-area assertion, and
the Windows ICO the resource stamper needs. The fork itself stays — its
mixed-DPI and proxy-isolation patches are Studio's too.
CI keeps one desktop Go gate per platform, now built against WebKitGTK
4.1 the way studio-build.sh links; the frontend legs, the Wails CLI pin,
and the 4.0 leg went with the app.
The desktop release line (release-desktop.yml and the desktop channel in
release-stable.yml) is untouched here: it still serves installs that are
already out there, and unwiring it is release-pipeline surgery of its own.
The privileged install was written into the desktop host: the pkexec call, the
helper's exit-code and phase protocol, and the dpkg ownership probe all named
reasonix-desktop and /usr/lib/reasonix directly. Studio needed the same
mechanism against different names, and copying it into a second host would have
made the security-relevant half of an update path exist twice.
It moves to internal/update, keyed by the line: InstallDeb runs the helper this
line declares, OwnsInstalledPath asks dpkg about the package this line declares,
and the classification of what the helper reported is shared. The desktop keeps
its own error values as aliases, so errorClass buckets and every errors.Is on
them read exactly as before.
Studio's GoToVersion now takes the package channel when dpkg owns the running
binary and the manifest publishes one, rebuilding the updater with the deb kind
so assetIn resolves the package instead of the tarball. A dismissed Polkit
prompt returns to "downloaded" with the verified cache intact rather than
reporting an error the user caused on purpose.
The tarball path is untouched, and platforms stays empty: it stages single files
and Studio's release is a binary plus the SPA tree.
Studio shipped a tarball, which is a download rather than an install: nothing
registers it, nothing upgrades it, and the versioned layout the desktop line
self-updates through stages single files, while Studio's release is a binary
plus the SPA tree it draws its UI from. dpkg carries a tree, so the .deb is the
form Studio can actually be installed and upgraded in.
Everything it names is its own. The desktop package owns /usr/lib/reasonix and
io.reasonix.desktop.update; Studio takes /usr/lib/reasonix-studio and
io.reasonix.studio.update, so the two install side by side without dpkg seeing
either overwrite the other's helper. /usr/bin/reasonix-studio is a symlink, so
os.Executable resolves into the library directory and frontendAssets finds the
SPA beside the real binary rather than beside the link.
The privileged helper is the desktop's source built with Studio's package name,
now a var rather than a const so the build can set it. It is still fixed at
build time — no runtime input can point it at another package — and Polkit
still authorizes one absolute path with one argument.
studio-manifest publishes the .deb under native_packages. platforms stays empty:
that is the tarball apply path, and it cannot publish a tree yet.
The desktop kept its own extensionFormSubmitter interface and asserted the
controller against it, because when it was written SubmitExtensionForm lived
only on the concrete controller. The comment said the alias could go once the
port grew the method. The port has: control.SessionAPI declares it, so every
controller reaching this code already satisfies the assertion.
Left in place it was worse than redundant. A test double that embeds a nil
control.SessionAPI to stand for "port only, no submitter" now satisfies the
assertion through the embedded interface and segfaults in the generated
forwarding method — the panic the test was written to prove could not happen.
The guard goes, the call goes straight to the port, and the case the double
stood for no longer exists.
The shared updater knew the desktop line by heart: the members a release archive
carries, the binaries they install as, and the launchers that survive a swap
were all spelled out inside internal/update. Studio ships one binary where the
desktop ships three, installs under a different name and answers to a different
dpkg package, so every one of those constants was a wrong answer for it — and
two lines that both wrote /usr/lib/reasonix/reasonix-update-helper would have
had dpkg watch one package overwrite the other's helper.
update.Line is that identity, declared by each host and passed in. Extraction
checks the members the line names, the Linux activation stages exactly those,
and the launcher search walks the line's own candidates. A member with no
installed name is one the archive must carry but this version does not persist,
which is how the desktop keeps shipping reasonix-guard for updaters that still
read these archives.
Behavior for the desktop is unchanged: desktopLine() restates what the package
had hardcoded. Nothing here turns Studio's self-update on — that needs the
manifest to list assets, which lands with the artifacts themselves.
Also brings one test comment back under its budget so the standards gate passes.
staticcheck flags parser.ParseDir as deprecated since Go 1.25, and it failed lint
plus all four desktop jobs — the one finding behind five red boxes. The reason it
was deprecated is that it ignores build tags when grouping files, which is what
this guard wants: an Options behind a tag reads the wrong catalog too. Reading the
directory and parsing each file says that outright instead of relying on a rule
that was retired for being imprecise. Probe-tested: still reports the file and
line of an Options that omits IndexURL.
resolveTriageProvider had no callers and only wrapped resolveTriage to drop two
of its results; its reason for existing moves into the doc of the function that
survives. A membership loop becomes slices.Contains, a Split becomes SplitSeq,
and one test comment comes back under its budget.
The bench carried a private estimator described as mirroring the kernel's own.
It did not: for a string with no wide characters, RuneCountInString(s) is len(s)
and is therefore always greater than (len(s)+3)/4, so every ASCII transcript
came back at four times its cost. The scripted provider sizes its window refusal
with that number, so a fold whose real input was ~19K tokens was rejected as
76K against a 64K window, and each generation after it inherited a larger
canonical to fail on.
internal/tokencount already answers this question once, splitting by script
because neither rule survives being applied to the other half. The bench now
asks it instead. Six generations summarize, fold input settles at ~18.9K and the
projection converges rather than the run wedging at generation two.
Describe canonicalized the workspace root but not the gitdir a linked worktree's
.git file points at, so the two sides could disagree on a path that resolves to
the same directory: on macOS a tree under /var/... and its gitdir spelled
/private/var/... produced two digests for one repository. A switch turned off in
the main tree then failed to apply in the worktree, which is the one thing this
package exists to guarantee.
Both sides now canonicalize. The stability assertion that was meant to guard
this compared Key(a) against itself and could never fire; it now compares two
spellings of one folder.
updater_install.go retired the local artifactKindTarball/artifactKindDeb
constants for update.KindTarball/update.KindDeb, but the two //go:build linux
files were not carried over: updater_install_linux.go still named the deleted
constants, and updater_deb_linux.go referenced update.Cached without importing
the package. Neither file compiles on macOS, so the break only ever surfaced in
CI, where it failed every desktop job on all three platforms.
One name for the artifact kind, defined where the cache already defines it.
The corpus graders already skipped a host without python3, but Windows resolves
a Microsoft Store stub of that name on PATH: it exits 0 and prints nothing, so
LookPath succeeded and the graders ran against nothing, reporting the corpus as
broken. Findable is not usable — the probe now wants a version string.
Four serve tests failed their own TempDir cleanup on Windows, which refuses to
unlink an open file. The handles are the usage and history catalogs, and no Close
reaches them by design: they are process-wide, cached per home so one process
keeps one handle. Both already export a closer; the tests just never called it.
installsource asserted an unpacked hook keeps mode 0755. Windows carries no
executable bit — os.Chmod only toggles read-only — so the claim is checkable only
where the bit means something.
completion's scratch filter compared a literal "/tmp/" prefix against a path the
ledger had already normalized, so on Windows it matched nothing and a scratch
write counted as a change. The real filter uses filepath.IsAbs and a folding
compare, so this was the test's assumption, not the product's.
acp's RPC helper allowed one call two seconds. session/new runs a full boot,
measured at 5.2s cold, so the package failed whenever the tree was tested at
once and passed alone on a warm cache. The budget now follows the test binary's
own deadline: a hang detector, not a latency assertion.
Both only ever ran where the assumption happened to hold, and pointing CI at
this branch is what surfaced them.
SaveShellSettings pins by proving the interpreter runs, so "/bin/sh" made the
test a POSIX-only one. It now pins whatever this host offers, using the option's
own Prefer field rather than a guess at the name-to-prefer mapping.
The MCP test isolates the config home, which leaves provider resolution on the
built-in presets — whose DeepSeek entries are kind "anthropic", never linked
into the cli test binary. pinProviderOffline keeps the setup about MCP.
plugin.go was 60 lines past the ceiling it is already 1200 lines over, and the
two groups nearest the surface are each a separate concern: where a connection
change is announced, and the bookkeeping that lets a background connect be
cancelled and its result recognised as stale.
Pure moves within the package, so behaviour is unchanged. repolint is now clean
repo-wide — this was the last finding outside the baseline.
Six are standard library, fixed in go1.26.6: net/url, crypto/tls, net/http,
encoding/xml, encoding/asn1, and x/net/idna's Punycode label check. The seventh
is golang.org/x/image, fixed in v0.45.0 — both modules use it directly, for webp
decoding and for the image compressor.
CI pins no Go version of its own, reading go.mod through go-version-file, so the
toolchain line is the whole change there. govulncheck locally: 7 affected before,
0 after.
The assertion wanted "OCR/image/vision tool"; the note has said "OCR/image
tool" since the wording was simplified, and control's own tests moved with it
while this copy did not. A test that pins a sentence fails when the sentence
improves — the same reason judgements here read structure instead of phrasing.
ImageRoutingTag is exported so a frontend can assert the note is present and
leave what it says to the package that owns it.
Record folded only Paths, leaving Showed and Created in whatever spelling the
caller had. The matchers then compared a folded path against an unfolded one, so
on Windows an output that carried a change never counted as review of it, and
CreatedInTurn — asked with the folded Paths — could not find a file it had just
recorded as created. That is the difference between a cleanup and a deletion.
CreatedInTurn now asks in the same identity it stores, which is required rather
than optional: folding on write alone would have broken it the other way.
snapshotPaths keyed its map by the raw string while its inputs disagreed about
spelling: ledger.TouchedPaths already folds case on Windows, a directory read
does not. The same file landed under two keys, and Receipt.Paths then named it
twice — a Windows mutation counted as two changes.
The ledger already owned the answer in normalizePath, unexported, so agent grew
a second idea of path identity. Exporting it leaves one definition: the snapshot
keys by it and keeps the original spelling for anything read by a human.
TestObservationNamesWhatAnOpaqueCommandTouched was failing on windows-latest for
this reason.
The pointer carried 20 head lines, so its price tracked line width: the bar it
implied ran 2214 bytes at 40-char lines and 8643 at 200. Wider output paid more
to leave context, which inverts what spilling is for.
The preview is now bounded by the instructions it rides on and cut at a line
boundary, so cost is the instructions plus at most the same again. Measured bars
across 20..200-char lines: 1005..1134 bytes. The head-line constant is gone —
the file's own comment already argued a head sketch is a guess by the wrong
party, while the code kept 20 lines of one.
Real run, one read_file of 24.6KB on deepseek-v4-flash: 25800 bytes of context
originally, 2175 with the line-counted preview, 797 now.
The budget was window-relative (window x 3 x 0.10, clamped to 32KB), so on a 1M
window it computed 300KB and always landed on the clamp. Measured against what
spilling actually costs — the pointer, 2875 bytes for 120-char lines — the bar
sat 11x above it, and everything from 3KB to 32KB paid full price for output the
model was already told to read back from disk.
The pointer is a pure function of the body, so build it and compare: no ratio, no
bytes-per-token estimate, no floor. spillPays requires the saving to cover the
cost rather than merely break even, because a pointer read back costs a turn.
This also removes the trap in the low direction — under a 1KB threshold the
pointer is larger than the body it replaces.
Real A/B on one read_file of a 24.6KB file, deepseek-v4-flash: 25800 bytes in
context before, 2175 after. Derived bars: 2214 bytes at 40-char lines, 5445 at
120 — a constant cannot track that, and cannot follow spilledOutputHeadLines
either.
These files never faced a gate: ci.yml ran on main-v2, where none of the studio
surface exists. The desktop test still built agent.RecoveryPauseError, a type the
kernel removed — topicActivityStatusFromEvent only reads e.Outcome, so an
ordinary error proves more: the outcome has to win over it.
build() carried the legacy migration inline at 1814 lines; it moves next to
continuesGeneration, which also keeps boot.go from growing. plugin.go's overage
was the one comment block studio added.
window_fit.go is desktop-tagged but main.go calls fitWindow unconditionally, so
the package built only with that tag. ci.yml's desktop job builds the module
without it, which is also what vet, lint and every editor do. Same no-op shape
as applyDockIcon in dock_icon_other.go.
Rebuilding the argument array from a slice left the old -tags value in place as
a positional argument, so go read "desktop production" as an import path. Only
the linux leg took that branch, which is why two of three platforms passed.
The manifest command's package comment was also over its budget: the -only run
that missed it was given an untracked directory, not the file.
ci.yml ran on main-v2 only, so the kernel changes this branch carries had never
been gated. Studio's own surface exists nowhere else, so it gets a separate
workflow rather than an if-guard inside a file main-v2 also reads.
release-studio.yml publishes studio-v* tags: its own environment, its own
catalog prefix, always a prerelease. latest.json lists downloads and no
platforms because the shared apply path names the desktop line's members, and
a manifest must not claim an install that would fail after the download.
Both update.Options here left IndexURL empty, which falls back to the desktop
catalog: a Studio release would have listed desktop versions and offered to
install reasonix-desktop over Studio. An AST guard fails a new Options in this
package that omits the field, because the failure mode is a new call site.
GoToVersion now asks the manifest whether this platform has an installable
asset instead of downloading one it cannot apply.
The verifier table will never enumerate every project's own runner, and
`./scripts/ci.sh` says nothing about itself — three measured attempts at
having a model read the command string ended in the harness that disproved
them. The information the table lacks is not in the command; it is in the
turn, which read or wrote that script.
complete_step already carries it. Its evidence takes kind=verification with a
command, and the tool refuses a citation whose command has no matching
successful receipt — the model names which command was the check, and the host
proves it ran. Only the readiness gate never asked: it consulted the static
table and the project's declared checks, so a corroborated citation sat in the
ledger while the turn was told to go and verify.
It asks now. What the model may decide stays exactly one thing — which of the
commands it ran was the check. That the command ran, that it exited zero, and
that it did so after the latest write are all still read off receipts, so a
citation cannot manufacture a pass, reach back past a later write, or rescue a
check that failed. Each of those is a test.
Delivery is untouched: there a citation still has to satisfy
IsDeliveryVerificationCommand, and the strictest tier keeps its static answer.
The lease refusal's wording changed with it, so four tests that asserted a
same-process holder is "another Reasonix process" now assert what it is.
Twelve live runs, 37 labelled commands, both tiers. The reverse direction —
asking only where the table already says yes — looked like the answer: it
withdrew every hollow check (`--collect-only`, `--no-run`, `--list-tests`,
`-count=0`) in run after run. It also refused one honest check per run, and
never the same one twice: golangci-lint run, then cargo test, then pytest -k.
Guarding by shape only moved it. Excluding commands whose work is named
elsewhere (`npm run lint`, `make test`, a script path) removed those failures
and the next run refused `golangci-lint run` instead. Excluding test selectors
removed that shape and the failure moved again.
Asking one command eight times says why. go test ./..., cargo test and
golangci-lint run answer CHECK 8/8; pytest --collect-only answers NOT 8/8;
npm run lint answers CHECK 3/8, because what that script does is not in the
command and the model is right to be unsure. The rest carry a small residual
flip — temperature 0 is not determinism on a hosted MoE model, where expert
routing depends on batch composition — and a dozen commands at a few percent
each is the one refusal per run that kept reappearing.
A gate that refuses an honest check a few percent of the time manufactures the
complaint it was built to fix: a turn that verified, told to verify. So the
escalation stays unwired and the harness stays, runnable, with the numbers
reproducible.
The bugs it found are the part worth keeping: classification billed to
compaction at the turn's price, a one-word lookup sampled at the provider's
default temperature, and a nil sink panicking in the deferred emit.
Three runs against deepseek-v4-flash, sixteen labelled commands. It scores
12-14 of 16 where the static table scores 7 — but the wins are not where the
feature was for.
`./scripts/verify.sh` and `bash scripts/ci.sh` are answered NOT in every run.
Those are the motivating case, and the failure is not the prompt's: nothing in
the command string says what the script does, and the prompt correctly tells
the model to refuse when it cannot tell. Naming a runner it does know — tox,
bazel, ctest, make smoke, npm run e2e — flips between runs, and the per-command
cache then freezes whichever answer arrived first for the rest of the session.
So the escalation is unwired. What the measurement is worth keeping for is the
opposite direction: `go test -run NoSuchTest ./...` and `pytest --collect-only`
run nothing, exit zero, and the static table accepts both today, while the
model rejected both in every run. Asking where the table says yes would tighten
the gate instead of loosening it — on two cases, which is not yet a decision.
Three bugs the measurement found on the way, all in the existing classifier
and all fixed here:
- Its tokens were billed to compaction at the turn's own price, so the cost of
a tier that exists to be cheap was reported as the expensive one. They are
reported as classifier usage on the triage model now.
- The call passed the turn's temperature, and OptionalTemperature drops a zero,
so a one-word lookup was sampled at the provider's default. Pinned.
- A nil sink panicked in the deferred usage emit.
The verifier table has the read-only table's problem, and the same fix was
already built for that one. A project whose check is `./scripts/verify.sh` or
`make smoke` gets no receipt the gate will accept, so a turn that really did
verify is told to run a verification — and every rewording is the same unknown
command again.
So the table gets shellsafe's escalation rather than more entries. It stays the
fast path and answers everything it knows; only a command it cannot name, and
only while a write is still owed a check, costs one classification. The verdict
is cached per command because the ledger is audited and the same command has to
classify the same way every time.
What the model may decide is deliberately narrow: whether a command runs a
check. Whether that check passed is read off the exit status — through
PIPESTATUS, so a pipe cannot launder a failure — and no answer from a
classifier can reach it. That split is the reason this is safe to ask at all;
the call is also context-free, so it is a router being asked about a string,
not the turn vouching for itself.
Being wrong here was already possible without a model: `go test -run
NoSuchTest ./...` runs nothing, exits zero, and the static table accepts it
today. The prompt names that class of command as NOT a check, so the
escalation is likelier to catch it than the flag table it backs.
turn_done already carries the kernel's reason. The pane put it in the run
strip's status label — one line, ellipsised mid-sentence, replaced by the next
turn, and absent from the transcript, so a stream error read as the session
having simply stopped. It lands in the transcript as a notice now, in the
kernel's own words: classifying failures here would be the client guessing at
something it cannot see.
Dispatched calls were left spinning by the same path. Whether work finished is
the turn's end to decide, so anything still running when it ends is closed and
says on its own card that it never reported back. A backgrounded command is
untouched — it answers the moment it is launched, so its card has already
settled.
A notice at error level also stops coming out amber next to ordinary
cautions; both rails were already in the sheet.
The effort menu listed auto twice: the kernel's level list opens with it and
the composer prepended another.
A runtime torn down without releasing its lease leaves an owner entry behind.
Every later bind then fails against it, and the refusal names the holder from
the lease sidecar — which this process wrote, so it names itself. The reader
is told to close the other Reasonix window and goes looking for a window that
was never there.
The desktop shell already recovers its own leftovers; the keeper behind serve,
the CLI and ACP did not, so Studio had no way out but a restart. It gets the
same fallback, guarded the same way: a readable info naming someone else is
respected, and reclaim takes the OS lock, which a live holder still holds — a
sibling binding in this same process keeps its lease, as the test asserts.
Whoever ends up refused, the message no longer calls our own pid another
process.
.picker is the app's own menu class — Menu.tsx renders it and app.css sets it
relative. Declaring it again further down the sheet won every cascade that
followed, so an absolute overlay with a float background landed on every menu
in the app, the composer's model picker included.
Naming the folder a listing answers for fixed reading it, not reaching it:
the pane still only spoke for whichever tab was in front, so a switch meant
for a project you were not sitting in cost a workspace change and the
conversation that came with it.
The listings and both switches now take a project. Reads come from that
folder's config and the activation store, which is enough to answer what is
declared and what is on; live connection state stays absent, because only
the session pointed at a folder can know whether its servers came up. The
rows that need the running session — retry, remove, install — are withheld
there rather than shown and quietly acting on the wrong folder. A folder the
shell has never opened is refused: the parameter would otherwise read and
edit any directory's config.
The picker offers each project once. Worktrees collapse onto their
repository, a name that collides gains the shortest trailing path that tells
it apart, and the count of local exceptions is on every row — with 32
remembered folders, the ones worth finding are the ones already changed.
A shell holds several projects at once while the runtime points at one, so
the settings pane silently answered for whichever tab was in front. Two
consequences: the reader could not tell which folder a list belonged to, and
a skill switch — a bare name in the user config — disabled every same-named
skill in every project at once.
Activation becomes one durable store for both capabilities, resolved project
layer before global layer before what the capability itself declares. The
project layer keys on the repository rather than the path, so the nine
worktrees of one repo are one project: a switch flipped in the main tree
still applies in a tree cut from it, instead of vanishing on branch.
Installing stays a global act; how far a server reaches is the separate
question the new local scope answers, without a second storage mechanism.
Every listing now carries the project it answered for, and a row that holds
a local exception says so and offers the way back.
The v1 file is read once and matched by re-deriving the path fingerprint —
the stored digest cannot be reversed into a path, so migration reads rather
than rewrites, and the old file is left untouched for a downgrade.
A sidebar filled with dozens of rows carrying the same title and the same turn
count: not new conversations, one conversation copied. Recovery lanes are per
live Session, so a resume, a runtime rebuild or a reopened pane each start a
new one and the same unsaved turns land in file after file. The depth cap
bounds the chain, never how many siblings one parent may accumulate.
A conflict now lands on a sibling already holding this exact content, and only
opens a lane when none does. Digests come from branch metadata, so it reads
sidecars rather than transcripts, and a path that turns out to hold something
else is never retried — that metadata records the digest at fork time and a
branch written to since no longer matches it.
The divergence itself is reproduced from outside the process, which is where it
has to come from: writers inside are serialised by snapshotMu and guarded
across processes by the session lease, so memory and disk can only stop being
prefixes of each other when something else rewrote the file — a sync client
resolving a conflict copy, a restored backup, a shared home. Distinct content
still gets its own branch; only identical content converges.
The corpus had 67 Python tasks and no Go one, while the agent's own repository
is Go. A compiled language is a different verification loop — a build before
anything runs, go vet, -race, a module path that must agree with every import —
and its defects have no Python analogue: a data race, a += in a loop that is
quadratic where Python's would be too, map iteration order that makes a test
pass only sometimes. Nine tasks cover that half as ordinary members of the
existing classes.
README already required every task to fail on the pristine seed and pass on a
reference solution, but only the no-solution half was enforced. A solvable task
whose seed grades clean scores the same whether the agent solved it or never
ran and reports 100% forever; TestSolvableCorpusSeedsMustNotGradeClean holds the
other 62 to it. All of them already pass. stageSeed now tolerates the optional
workdir the README documents.
Harness metrics move out of the work dir. The agent reads what is in front of
it, and one observed run spent a tool call on .run-metrics-1.json.partial —
snapshots already dropped these files, which kept them out of the grade but not
out of the agent's context.
One observed turn wrote 832 reasoning records carrying 6.5k characters, and a
two-minute benchmark cost a 484KB trajectory whose content was 19KB — 25x
envelope, and one write syscall per record because each is flushed. The only
timestamp any reader consumes is the first: cmd/e2ebench keys time-to-first-
token off it and drops the rest.
Adjacent same-kind increments merge, TS stays the first one's, and the count
and end time ride along. Records drop 86% and the digest cmd/e2ebench prints is
byte-identical across the change. A cap bounds what a kill can lose, and
anything carrying more than its text is left alone so a field added to the wire
later stops merging rather than vanishing into a neighbour.
The sweep removed artifacts one at a time and returned on the first refusal.
The transcript went first and the event log — the authoritative one — fourth,
so a Windows host holding that log open left the conversation neither present
nor gone: the caller saw a 500 while the sidebar row was already unrecoverable.
The marker now goes down before anything is removed, every artifact is
attempted, and whatever survives keeps it for ReconcileCleanupPending.
The guard asked the pane map whether the session was someone's current
transcript, which is narrower than "is anyone writing this file" — a recovery
branch or a mid-rotation session is held without being anyone's current path.
It takes the removal guard instead, so the answer survives the delete; probing
and then removing leaves a window for a writer to arrive and lose its lock file
underneath.
SseHub flattened refusals into their message text, so a coded 409 reached the
screen as raw JSON or as a filesystem error naming a path. It parses the code
now, like SsePort already did.
A transition on grid-template-columns does nothing when the track list holds a
minmax(): that property only interpolates between plain lengths, so the rails
were snapping shut with the animation written and silently ignored. The
interpolation moves onto two @property-registered lengths and the columns read
them; dragging switches it off, or the rail chases the pointer.
Closing a pane becomes awaitable. Deleting a conversation has to close its pane
first and then wait, because the kernel refuses to erase a transcript its
runtime still holds — firing the close off and deleting in the same breath
races the teardown.
perf/panels.mjs measures what has no error to report: a re-introduced minmax()
would put the rails back to snapping without failing anything else.
A false-progress ratio needs a check that ran twice — nothing else can show a
fail→pass edge. Runs where no check repeated reported 100%, which reads as
every claimed advance being fake when the truth is that none was observable.
The digest now counts revisits and says unmeasured below one.
A start delay was one number over two different things. A call that waits
because a sibling is still executing is a serial batch behaving correctly; a
call that waits with nothing running is scheduling cost. Attribution is per
call — whether another call occupied that call's dispatch→start window — so a
batch that mixes both no longer files every delay under the same heading. On a
real run: queue p95 17.9s became queue p95 1ms plus serial wait p95 17.9s.
Splitting the render out of trajectory.go keeps it under the size ceiling.
Delivery rejects `python3 -c` and `node -e` in any arrangement, but that gate
sat last, after every shape block. The shape blocks answered first, and their
ways out all named a call this one refuses: a probe followed the mixed block's
"run that segment as its own call", ran a bare `python3 -c`, and was refused
again for a reason the first message never mentioned.
Moving it first costs no new text and ends the chain. The three arrangements —
interpreter first, interpreter last, interpreter alone — now get the same
answer, the one that says why and points at read_file, node --check, or a
script file.
TestDeliveryProfileBlocksMixedVerificationBeforeItBecomesMutation reached the
mixed block through a `python3 -c` command, which no longer describes what it
tests; it uses cp now and still pins the named segment.
Two faults hid one signal. The fail→pass edge was keyed on the raw command
string, and an agent never re-runs a check byte-for-byte — it writes
`go test ./... | head -60` first and `go test ./... | tail -15` after. The
verdict then came from the receipt's own exit status, which for a pipeline is
head's, so a failing suite read as a success that never needed redeeming.
Objective and Regression therefore never fired in any run, and the
false-progress ratio that divides by them reported 100% every time. Both
answers already existed and this path asked for neither: VerificationIdentity
reduces a command to the check it runs, VerificationOutcome reads the host's
PIPESTATUS classification. The offline digest mirrors the same identity so it
scores the edges the live tracker does.
Same task before and after: objective transitions 0 → 1, false progress
10/10 (100%) → 5/9 (56%).
Ordinary mode names the segment that tripped the block; delivery answered with
one fixed sentence that named nothing. TestMixedBlockNamesTheSegment already
says what that costs — "which is how one block becomes three" — and a delivery
run spent exactly that: refused at calls 6, 8 and 9, rewriting the shape each
time against three identical messages.
It also stopped short of the other half. Ordinary mode's way out is '&&', which
delivery refuses as well, so a run that follows the generic advice earns the
same block again. The message now says so.
The same run after the change: refused once, then split the command into three
separate calls.
parallelisable asked the registry whether a tool is read-only, and bash is
writer-capable in its schema, so no bash call ever joined a parallel batch —
which is most of what an agent runs. The host already resolves a concrete
invocation to read-only after parsing its arguments; permission, mutation
accounting and evidence all act on that fact, and only the partition did not.
Measured end to end: two greps over 32MB files now start in the same
millisecond and finish in 258ms, where serial execution took the sum.
CompoundLeafCommands only treated loops, branches, subshells and blocks as
compound, so a pipeline or an && chain fell between the two classifiers: the
single-command one cannot read several commands, and the leaf one refused to
receive them. Every `… | head` therefore counted as a write, which is the
shape agents reach for constantly.
A BinaryCmd is now compound, so each stage is classified on its own and one
writer anywhere still ends it — `| tee`, `| xargs`, `| sed -i`, `&& rm -rf`
and `tee >(sh)` all stay writes.
99ef4b2f0 removed the archive path and its field on HistoryMessage but left six
readers and a mock behind, so `tsc --noEmit` fails on this branch with seven
errors across bridge.ts, transcriptStore.ts and useController.ts. main-v2 still
has the field, which is why the break is invisible there.
Nothing renders item.archive — the only readers were the store, the controller
and one mock — so the field goes rather than coming back. `pnpm --dir frontend
build` runs tsc, so this would have failed the desktop leg on merge.
timeout_seconds only tightens the host cap, but a run reaching for a long job
asks for the length the job needs: one observed run asked for 600s and 900s
under the default 120s cap. Both were clamped, and the timeout then advised
"raise timeout_seconds" — the number the cap had already overridden.
The refusal now says which cap won and how much of the request it took, and
points at the mechanism that can actually run longer. A run under a 5s cap that
asked for 90s reads it and moves to run_in_background on the next call instead
of asking for more seconds.
Three paths stop a call before it runs, and only two of them said so in
structured form: the batch dependency barrier and bash's own preflight set
execution.failurePhase, while a permission refusal carried nothing but an
error line. A gate that misfires was therefore invisible to every digest —
the agent just retried and the round count grew.
Permission refusals now carry the authorization phase through the same
constructor the barrier uses, and the trajectory digest counts refusals by
the gate that caused them.
POSIX `command -v`/`-V` print how a name would resolve and execute nothing,
which makes them readers like `which`. Grouping them with exec/nohup/sudo
refused every environment probe an agent opens with, and the batch dependency
barrier then skipped the read-only probes queued behind them, so the agent
re-ran each one alone.
Measured on the same task before and after: 26 tool calls to 14, 21 model
rounds to 14, two dependency skips to zero, same conclusion both times.
REASONIX.md told the model to run `go run ./tools/repolint -only ...`, which the
host classifies as an unknown program that might write — so a delivery run that
followed the instruction could not cite the result. One observed run was refused
for `gofmt -l`, reached for the repolint command the file recommends, and was
refused again for the same reason.
A `make` target is the entry the host already recognizes, and Makefile is where
this project declares its checks. Nothing in the classifier changes.
The alternative — letting a project name its own verification commands in config
— was rejected. Delivery deliberately refuses to escalate (see
mixedShapeClearedByEscalation) because it only accepts what the host can confirm
by itself; a config channel would let the audited party define the audit.
An Ask decision with no interactive approver came back as "the user declined
this tool call — ask how they would like to proceed". Nobody declined it, and
the advice sends the model to consult someone who is not there. A headless run
asked to write one file spent two write_file calls on it and closed by offering
the user three choices about the file's contents, none of which was the reason.
denyPermissionApprover now answers with what actually happened. The same run
afterwards refuses once and leads with the permission mode as the fix.
The gate already threaded an approver reason through for exactly this; the
headless approver was the one that never supplied it, while the ask tool has
been saying "No interactive user answered" all along.
The refusal said "use a project test/check/lint command", so a run that had just
been refused for `gofmt -l` reached for `go run ./tools/repolint` — this repo's
own lint command, and refused for the same reason. Naming the category invites
the second wrong guess.
VerificationCommandSummary is already the single source for the accepted set and
already travels with the inline-interpreter block; it now travels with this one
too.
The client posted {text} while the handler reads {goal}, so the body decoded to
an empty string and took the clear branch. Against a running server: {text:AAA}
answers 204 and leaves the goal blank, and a later {text:CCC} erases a goal that
was set. SetGoal and SetPlanMode(false) were never reached.
The endpoint had no test at all. The new one pins the wire key rather than the
status code, since a 204 is exactly what the broken call returned.
`go build ./x && go test ./x | tail` was refused as a maskable mixture, but the
pipe-status probe already recovers each stage's status: a real run of that shape
reports exit 0 and verification failed. The block was guarding against a masking
the host had stopped suffering, and cost a round trip on an everyday shape.
The shape test the probe used to decide whether to inject itself moves to
evidence, so the gate and the probe read one judgement and cannot disagree
about a command.
The exemption covers exactly one masking source. `;`, `||`, and a backgrounded
mutation drop a status before the final pipeline, and no per-stage report brings
that back, so those stay blocked. Delivery is untouched: there a mutation
invalidates the receipt whether or not the exit status survived.
Splitting a long test file scatters one subject's table across files that then
have to be read together, so the ceiling only ever bought a worse layout. The
rule retires entirely rather than gaining an exemption flag; complexity and
struct-state already stand down for tests, and size was the last one that did
not.
The baseline drops the 74 test-file-size entries by hand rather than through
-update, which would have absorbed unrelated debt the tree carries today.
The host cap (bash_timeout_seconds) was the only foreground deadline, so a
command whose cost the model could not predict spent the full cap before
saying anything. A per-call timeout_seconds now rides the same resolution the
host cap already uses: it only tightens, never extends, and with the cap
disabled it becomes the only deadline.
grep and glob each carried a byte-identical clamp; both now share toolTimeout,
which bash reuses by passing its cap as default and ceiling.
A timeout that produced nothing says so — silence and partial output call for
opposite next moves, and the output alone cannot tell them apart — and names
the way out, which differs by whose deadline fired.
ClassifyMutationRisk raises a pathless mutation to RiskHigh only when its
MutationEvidence is MutationProven; anything else falls through to RiskLow.
The receipts rebuilt from a task artifact set Mutation but left the grade
empty, so a background writer recovered after a restart came back as low
risk — exactly the downgrade the opaque recovery exists to prevent, and what
three tests in this package had been failing on.
Both construction sites now share recoveredTaskMutationReceipt, which states
why the grade is not optional. It lives in artifacts.go: the artifact is what
proves the mutation, and jobs.go has no room left under its size budget.
"This argv runs a program written in the call itself" was answered twice.
Permission knew `bash -c`, `sh -lc`, lua, rscript, osascript; evidence
knew node, python, ruby, perl, php and deno and nothing else. So
`bash -c '...'` was code the approval layer refused to audit and an
ordinary program to the ledger that recorded it.
ArgvCarriesInlineCode is now the one rule, taking the wider of the two,
and both ask it — the same move ArgsMakeReadOnlyCommandWrite made for the
arguments that turn a reader into a writer. executableBase went with it:
two identical copies of "strip the directory and .exe".
This is a table, and it stays one: which flag makes an interpreter read
its program from the command line is knowledge about those programs, not
a shape any parser can derive. What it must not be is two tables.
A search that matched nothing came back to recovery as a list of English
phrases to look for: "no matches", "no files found", "0 matches", "not
found", "no results". Four of those five no tool has ever printed. The
fifth worked only because grep and glob happen to print it — a sentence
the host writes for the model, re-recognised as if it came from outside.
tool.NoMatches is that sentence, once, with a writer and a reader. The
guess is gone, and so is the drift a reworded or translated line would
have caused: the gate now reads what the tool actually emitted.
Two rules for one question had drifted apart. The coverage check now asks
whether an output carried the change; the review gate still read command
names, and accepted `git status`, which prints paths and no content, and
`echo internal/a.go`, which prints one path and nothing else. Either was
enough to make a turn look reviewed.
Both are gone. The gate asks for the change's content, exactly as the
coverage check does, and falls back to "the turn looked at something"
only where it must: a mutation from before this ledger, or a shell write
that named no path, is unknowable either way.
That fallback is what the retired table added nothing to. A plain
`git diff` counted because the host classifies it read-only, not because
its name was on a list — and the list could not tell that apart from
`git status`, which is why it accepted both.
`sed -n '1,80p' f` is a mutation to this host. So is `git -C dir status`,
and `mkdir -p "$TMPDIR/probe"`. Not because anything believes they write,
but because proving they do not means reading sed's own script language,
git's global options, or a path that only exists at expansion time — and
each of those answers is a table that covers one spelling and misses the
rest. The cost lands on the turn: phantom changes in the completion
report, a verification owed for a file nobody touched.
A call the host could not classify now takes a whole-workspace scan
before it runs and another when its receipt is written; if the tree is
byte-for-byte as it was, the receipt says so. Nothing is predicted, so
nothing needs a table, and it works the same for awk, perl or a program
written this morning.
The walk is unfiltered on purpose — npm install and a build write exactly
where ignore rules point away, so a filtered scan would miss the largest
writes there are. It skips only the VCS store, which `git status` rewrites
on its own. Past 50k files it reports itself incomplete and settles
nothing, and a backgrounded job never settles: its receipt is written
before the job has written anything. Every one of those falls back to
today's behaviour rather than to a guess.
Measured on this repository: 17ms per scan in a worktree, 126ms with
node_modules and build output present, against ~6.4s per model round.
Permission is untouched — it must answer before the call runs, so it
stays predictive and fail-closed.
A turn that ends by reading its own diff writes `git diff --stat && git
diff`, or puts a `cd` in front, or prints a separator between two halves.
The host asked whether the command's shape implied it had printed a
file — one statement, two arguments, no suppressing flag — so every one
of those shapes was rejected, and a turn that had reviewed its whole
change set was reported with review gaps. It could not be otherwise:
the receipt's output length is the whole command's, so a compound one
could always have printed something else.
So stop reading shapes. When a change is made, the preview the writer
already produced names the lines that differ; when a later call returns,
the host asks whether its model-visible output carries them, and records
the answer on the receipt. Matching is on substrings, so a `+` from a
diff, a line number from `grep -n` and a pager's indent all read the
same — the formats a shape rule would have had to enumerate.
This retires commandShowsContentForPath, commandShowsWholeGitDiff and
their helpers, including the suppressing-flag table and both command-name
switches: 168 lines of shell-shape reading for 60 of content matching.
A read receipt still covers its own path, unchanged.
Verified against a real run: its `git diff --stat && git diff` output
carries both witness lines and counts; the `--stat` half alone does not.
A server showed "not connected" while the agent was using it perfectly well,
and the connect button sat on "connecting…" forever.
Status views refresh on MCPSurfaceReady, and that event was only ever emitted
after prompts or resources finished listing. A tools-only server has neither —
windows-mcp, in the report — so nothing was ever emitted for it, and the view
kept showing the state it read at boot. The kernel was right the whole time:
connecting clears the recorded failure. Nobody was told.
The announcement moves to where the state actually changes. The Host holds the
sink rather than taking one per call, because a status change has no caller to
hand it one: a cache-miss server connects on its first real tool call, in the
background, long after whoever configured it is gone. That is also why the
existing StartPhaseB path could not have covered this — it has no callers at
all, so the prompt/resource announcements never fired either.
Also on the composer: the effort menu listed six rungs for every model, while
the kernel declares per-model supported_efforts and refuses the rest. Picking
one a model does not have was answered downstream with a refusal and nothing on
screen, which reads as a dead control. The menu now offers what this model
actually has.
The check that turns `find -delete`, `sort -o` or `git tag v1.0` back into a
write lived in three packages, and they had already drifted: only permission
knew that naming a tag creates one, so evidence recorded such a turn as having
changed nothing at all. Two of the copies also carried a `sed -i` branch no
call could reach, because sed is not in the read-only tables to begin with.
ArgsMakeReadOnlyCommandWrite is now the one rule, taking the strictest form of
each case, and permission, evidence and the nested-substitution check all ask
it. The unreachable branch is replaced by the reason sed stays out: it writes
through its own script language (`-i`, `w file`, `s///w file`), which nothing
here parses, so a flag check would cover one spelling and miss the rest.
fitted stopped shrinking by a fixed margin when the size became a ceiling, so
the test's own guard — "still not wider than the screen" — was still gated on a
constant that no longer decides anything. It now runs whenever the screen
reported a size at all, which is the condition the assertion was always about.
The prompt tells a run to keep probes out of the repository and now names
$TMPDIR. Bash writes there — that is where the variable points — but
write_file refused it, so the here-document block's own advice ("write
the file with write_file") led straight into a wall. One observed run
worked around it with printf and lost three rounds; an earlier one wrote
its probe into internal/agent/ instead, then had to rm it.
The writers now accept the session's own temporary directory, the same
one bash writes through, and a refused write names it. Its writes are the
kind the host can account for: a path, a receipt, a diff.
That made the second half visible: a probe under $TMPDIR armed the
post-write verification gate and appeared in the completion report as an
unreviewed change, so a turn that touched nothing in the repository was
told it had gaps. What the turn owes is measured on the work product, so
a path outside the workspace is not what the readiness gate and the
report count. Where bash wrote is often unprovable — those receipts name
no path and still count, as they did before.
Confirmed from the report: 125% scaling on 1080p. So the fix that landed —
shrink to fit — was aimed correctly but is only the floor of it, and it corrects
a window that has already been drawn.
Two things on top of it.
The preferred size is now a ceiling. A window opens at whichever is smaller,
1440x900 or most of this screen, where "most" is proportional rather than a
fixed margin: 64px of air is cramped on a 4K panel and generous on a laptop,
while nine tenths reads the same at every size. At 125% of 1080p that is
1382x777 instead of 1440x800 — the earlier version left the width untouched and
squashed only the height, which is the same window in the wrong proportion.
And the window starts hidden, shown from the same place once it has been
measured. Sizing a window that is already on screen is a flicker on every
launch, and on the machines where this matters it would be a flicker every time.
The package does not build in this tree — evidence/taskcontract are mid-refactor
elsewhere in the working copy — so the arithmetic was checked on its own rather
than through the test that encodes it. Still no Windows machine here: what is
verified is the decision, not the platform calls it drives.
Reported from Windows: the title bar starts above the top of the screen, on a
1920x1080 display — so not a small monitor.
Wails sizes windows in logical pixels. That display at Windows' common 125%
scaling is 1536x864 to lay out in, and 150% leaves 1280x720; the default
1440x900 fits neither. Centred in 864 the top edge lands at -18, which is the
title bar exactly. On Windows the frame is off and that bar is drawn by the app,
so what goes off-screen is also the only region that can drag the window back —
there is no recovering from it by hand.
The window is measured against the screen it opened on and shrunk to fit, and
centred either way, since Wails makes no promise about where a Windows window
lands. The arithmetic is a pure function so it can be tested from any platform:
the failing cases here are 125% and 150% of 1080p, which is what shipped.
Untested on Windows itself — I have no machine for it. What is verified is the
sizing decision, not the platform call it feeds.
The folder panel's title was a Chinese string compiled into the shell, so an
English interface opened a Chinese panel. It sits outside the webview, which is
why the frontend's catalogue never covered it.
It reads from internal/i18n now, but through a new Catalog(tag) rather than
DetectLanguage: the desktop interface language is a setting of its own and the
kernel's is another, and one process holds both — installing one would silently
retag the other. Catalog returns a catalogue and leaves M alone, which a test
pins, since the whole point is the absence of a side effect.
The title itself lands in all three catalogues, so the existing completeness
test is what refuses the next one that ships in one language.
A grep that matched nothing exits 1 and prints nothing, so the run saw
`error: command exited: exit status 1` and no more. It could not tell
absence from breakage, re-ran the same search with small variations for
sixty rounds, and collected a recovery steer each time telling it to
diagnose the tool.
A call that printed nothing, that the host proved changed nothing, and
that carries no verification conclusion reported a result: grep,
`test -f` and `git diff --quiet` all report absence that way. Say so in
the body, and leave recovery out of it. A verification keeps its old
reading — its exit status is its verdict, silent or not.
`cat > f <<'EOF'` inside a compound statement fell into the unparsable
bucket, whose message points at read_file and grep — advice for someone
inspecting, given to someone writing a file. The observed run hit it
twice, two hundred seconds apart, and learned nothing in between.
The parser reads a here-document fine; what an approval cannot see is
its body, which is file content rather than arguments. That is a
different gap and now says so, and points at write_file.
A run told only the workspace path prefixes every shell command with
`cd <root> &&` and spells every tool path out in full — 50 of 51 bash
calls in an observed run. The prefix is not only tokens: it turns a
simple call into a compound statement, and the evidence reader credits
neither its content nor a whole `git diff` as review of the change set,
so a turn that did review its own diff was reported with gaps.
The scratch line had the same shape. It says to keep probes out of the
repository and use a temp directory, without naming one; the run reached
for /tmp, was refused, and wrote its probe into the repository instead.
$TMPDIR is the session-private directory the host already provides.
Users concluded the app cannot create a project. It can — the picker has
CanCreateDirectories set and macOS puts a New Folder button in the panel — but
every word around it said otherwise: a rail footer reading "add a folder" and a
panel titled "open a working directory" describe picking something that already
exists, so nobody went looking for the button that was there all along.
The entry now says what it does, and the panel repeats it at the moment the
choice is made. No new path: the one that existed was simply unannounced.
Three things the rail got wrong, all reported from using it.
The marks drifted while dragging. They were placed in pixels, and a block
mounting swaps its estimated height for its real one — every pixel-derived
position on the rail moves a little while the content underneath sits still.
They are placed by entry count now, which mounting cannot change. Entries are
also the better answer to "how long was that turn": what it produced, not how
tall it happens to render.
The drag fell behind the pointer. What can be dragged is the track minus the
box, and what it covers is the content minus one screen; using the whole track
against the whole content leaves it slow by exactly the ratio of the two. Both
are read per move rather than captured on grab, because blocks keep mounting as
the drag travels.
The box could not be grabbed at all: each mark's hit box spans the rail's full
width and they are painted after it, so the press never reached it. The two now
occupy their own columns — the scrollbar at the very edge, the marks to its
left.
Jumping measured with offsetTop, whose nearest positioned ancestor is .pane —
which does not scroll. That reads "where in the window", and writing it back as
scrollTop barely moves. Measured against the scroller now.
repolint went red on comment length in four places, which blocks the pre-push
gate for everyone working in the tree. Each block keeps what it was saying — why
complete_step exists at all, why a path's shared head goes before its middle,
what ReadOnly buys a batch, why the reason for a contextual tool lives on the
tool — in fewer lines.
The two test-file-size overruns are left alone: shrinking those means splitting
test files, which belongs to whoever is adding the tests.
The escalation path asked a model about every command the static tables could
not read, including ones the user had already approved. A rule in the config is
a person's own answer, written down; asking a model to second-guess it is both
slower and less authoritative, so a matched rule now short-circuits the ask.
Telling the two apart takes care: Policy.Decide returns Allow for a writer under
the auto fallback exactly as it does for a rule that matched, because Mode's zero
value is Allow. Neutralizing the fallback is what separates them — with Mode set
to Ask, an Allow can only have come from a rule. Reading the rule list directly
would mean re-implementing bash's segment matching, which is the sort of second
copy that drifts.
The classifier generalizes to one call shape, since a second host question would
differ only in its criterion and its affirmative word.
A verification classifier is deliberately absent. The static tables miss a
project's own checks, but a model misses them for the same reason the tables do:
`python3 test_x.py` and `python3 deploy.py` are the same command shape, and which
one is a check lives in the project, not the command. That question already has
an answer that does not guess — a project names its checks in REASONIX.md, and
declaredChecksRanAfter takes the classifier out of the decision entirely.
Running real tasks against a real key, three of four verifications in one turn
came back unreadable. All three were the same shape — `go vet ./... && go test
./... 2>&1 | tail -5`, or a banner echoed before the suite — and the probe that
was supposed to recover the suite's own status only handled a command that is
nothing but one pipeline.
PIPESTATUS describes whichever pipeline actually ran, and which one that was is
answerable whenever the candidates differ in width: `go vet && go test | tail`
can end in a one-stage command or a two-stage pipeline, so two statuses can only
have come from the second. Equal widths stay refused — attributing a status to
a pipeline that never ran is the error this whole path exists to avoid.
Same task re-run: three unreadable verifications became zero.
Also: a check that failed before the latest change no longer counts as a gap
once something fresh has proven the tree. A project whose rules ask for a
failing test before the fix produces one every time, and reporting it back
after the green run reports the bug as an outcome of the work that removed it.
The neighbouring stale and inconclusive cases already worked this way.
Two vertical strips down the same edge saying the same thing — the viewport box
and the scrollbar thumb both answer "where am I" — read as a doubled scrollbar,
which is what it was.
So the transcript stops drawing the native one. The box is permanent now
instead of appearing on approach, and it drags: it inherited the job, so it
inherits the handle. A drag releases the follow the same way a wheel does,
through the same call, because it is the same intent.
⌘↑ / ⌘↓ walk the marks. Which one you are at is read from the viewport rather
than from a cursor the rail would have to keep in sync, so the keys always agree
with what is on screen. A text field keeps them — inside the composer they still
mean what the system means by them.
In a session you speak a handful of times and it works for the rest. So "what
did I ask it to do" always has a small answer — and it is buried under a few
thousand lines of output, reachable only by scrolling.
The rail marks those messages down the right edge, positioned where they
actually are: the gaps are how long each turn ran, and a mark is as thick as
that turn's change was (checkpoint.files). A viewport box says where you are
now, which is what separates a map from a list of bookmarks.
Pointing at a three-pixel line is not something to ask of anyone, so the whole
rail is a track: the pointer's y decides which mark it means and the nearest one
is drawn as held. The first cut had each mark move on hover, which took it out
from under the pointer — hover dropped, mark returned, hover again. The hit box
is fixed now and only the line inside it animates.
Marks locate by block, not by message. Under virtualisation most messages have
no node at all, but their block is always there holding its height, so a jump
lands on the block first and settles onto the message once mounting brings it
back. The jump also clears the follow the way a gesture would — otherwise the
next frame would pull the reader back to the bottom they just left.
Building a small CLI from scratch reported six unreviewed changes against six
files the model had just authored. The review gap asks whether the result of a
change was inspected — a real question for an edit, which has a before to
compare against, and none for a file whose entire content is the write itself.
Reading it back compares the model's text with its own text; what answers for
those files is the check that ran over them, which the report already counts.
So a path this turn created counts as reviewed until something edits it again,
at which point there is a before once more and the requirement returns with it.
The same run now reports two gaps instead of eight, and the two are the files
that were written and then edited.
Also here: golangci-lint's two findings on the observation code from the
previous commit.
shellsafe enumerates 145 commands and will never enumerate them all: a new
formatter, linter, or query tool arrives every week, and each one that falls
through reads as "might write". A read-only command classified that way blocks
work — a real run spent seventeen consecutive rounds trying to see one failing
test, rewriting the filter each time a pipe segment tripped the mixed-command
contract.
So the tables get an escalation path rather than more entries. They stay the
fast path and answer everything they know; when they come up short and the host
is about to refuse, one classification call decides, and the verdict is cached
so a segment is asked about once. triage_model points those calls at a cheap
tier — empty falls back to subagent_model, then the main model, so it works
before anyone configures anything.
The escalation cannot widen what actually runs. The OS sandbox still bounds
every write, the verdict is refused unless the reply is exactly READONLY, and
anything unestablished — no provider, a timeout, a hedged answer — lands on the
refusing side. Delivery never escalates: there a mixed command is refused for
what it does to the receipt, not for what it might write.
Two things this cost to learn, both from running it rather than reading it:
- A one-word answer needs thinking turned off. Under a tight token cap a
thinking model spends the whole budget reasoning and returns nothing, so four
classifications in a row silently failed.
- The classifier gets its own provider instance from boot. Borrowing the turn's
own would put extra calls into a stream the run is mid-conversation on — which
is exactly what hung the agent tests against a scripted provider, for the full
ten-minute default timeout.
repolint grows -only, which reports the budgets of named files instead of the
whole tree's recorded debt. A change could not tell its own violations from
inherited ones; the model in one run tried to build a git worktree to compare
against, and the sandbox refused it. Repo-wide ceilings still report, because a
file can push the tree past one without exceeding its own budget.
Carries the rest of the in-progress work in the same snapshot.
Two findings from a real session, both about telling the model something it can
act on.
The host answered an out-of-context call from a switch keyed on tool name,
while the condition it was reporting lived in that tool's own ProviderVisible.
Half a contract in each place, and the half in the host is the one nobody
remembers to extend: add a contextual tool and it gets the generic sentence.
ContextualReasoner puts the reason next to the state it reads, and a registry
test refuses a contextual tool that cannot give one — submit_plan and
conclude_no_changes turned out to already be in that position.
The dynamic surface is deliberately not the fix here. ContextualTool's contract
says schemas stay static for cache stability, and a list that shrinks when a
goal ends would break the prefix every turn. Availability is answered when the
call runs; what this changes is only the quality of that answer.
Second: complete_step already cites the receipts it has, but shortened each to
its first eighty characters. Under a deep root that is the shared prefix, so a
turn was told to cite one of three identical strings. Paths differ at the end.
The shared head goes first, then the middle is elided — the part that tells one
from another is what survives.
It was a table you could read and nothing else — the one record of where a
turn's time went, with no way to get it to anyone who was not looking at that
screen at that moment.
Export writes what a row is rather than how it is drawn: seq, at, dur, kind,
tool, plus the rendered line as text and any detail under it. Four of those are
the timing, which is the point of keeping it; the text is there so the file
reads as itself without the app.
The path out follows the one plugin export already uses: a webview starts no
downloads, so the shell writes the file through a save dialog and reports where
it went, while a served tab downloads it. SaveText is general because the shell
has no business knowing what the frontend assembled — the trajectory is simply
the first thing that needed disk. Handing bytes to a browser moved next to the
ports rather than into one, so the fixture takes the same path a tab does
instead of claiming a file was written somewhere it was not.
An investigation that was told not to change code still ended in error. The
model wrote a scratch probe, ran it, deleted it, and answered correctly — and
the host, seeing a write with no verification after it, reported a failed run.
The static classifier could not have known better. `go run x.go && rm x.go`
decomposes into commands it does not recognize, so it lands in unknown: a
mutation with no paths, about which every later question answers "something,
somewhere". Teaching it that `rm` removes its arguments would start a table of
command semantics that never ends and is wrong at the edges.
So the host watches instead. Before a mutating call it records the state of the
paths the turn already touched plus the call's own targets; afterwards it reads
which of them changed, and which it watched come into existence. Classification
is only ever sharpened — a call that changed nothing among the watched paths
stays unknown, because it may have changed something outside them. `sed -i` on
a file the turn had read now names that file instead of shrugging.
Knowing what appeared is what makes it safe to know what vanished: the baseline
for what a turn still owes is the latest change still on disk, and a file the
host watched appear and then vanish is not one. A write it never saw created is
assumed to survive — an unresolvable path looks exactly like a deleted one, and
only one of those may be waived.
Same investigation, re-run: finishes clean, workspace empty of scratch files.
An ordinary fix still verifies as before.
Measured against a real 262-second task: model rounds accounted for 99% of it,
tool execution for 0.6%. The timeline drew only the second number. Twenty-four
rounds — the thing the wait actually consists of — had no row at all, because
the table recorded events rather than activities, and a round is two events far
apart.
A row is now one activity: opened by the event that starts it, settled by the
one that ends it, both halves on the same line. The kernel already names them —
stream_attempt carries begin/commit under one id, a tool call carries its id
into its result — so the pairing is read from the stream, never guessed. A
tool's duration comes from the kernel, which measured it; a round's comes from
the wall clock here, which is what the reader waited.
Falling out of the same change: one call is one line instead of two, tool
errors take a distinct kind, and tool_progress stretches the bar it belongs to
instead of opening a row. Progress output is not copied into the table — this
records when, not what.
Two findings from running Python, JavaScript and investigation tasks against a
real key.
A model reviewing its own work reaches for `git diff`. In a workspace that is
not a repository it finds out by failing — twice, since the first attempt is
usually a compound command the safety gate rejects for other reasons. Every
non-repository run in the traces paid this. The environment section already
states the OS, the shell, and which tools are installed; it now also states
whether the workspace is under version control, read from the filesystem so it
costs nothing at boot and cannot flap into the cached prefix. In a re-run of the
same Python task the model made no git attempt at all.
Delivery reported one gap as three. A sign-off that cites a passing check is
not a valid sign-off until the change has also been reviewed — correct, but the
gate then also demanded "run relevant verification and cite that successful
command", which the model had just done and watched pass. The cited-verification
question is now asked on its own, so the message names the review and only the
review.
A bare binary draws its window fine, so nothing looks wrong until a native
panel opens: LaunchServices only treats a bundled process as a real GUI app,
and NSOpenPanel takes focus and closes in the same beat. "Add a folder…" reads
as broken, and the search goes to the frontend, where nothing is wrong.
make studio builds the frontend, builds the shell, wraps both in an .app and
opens it. The bundle symlinks frontend-next beside the executable — assetsFS
looks there first, which frees the launch from the working directory `open`
gives it (that is "/", and the binary exits before drawing anything).
The row under the composer was five identical grey pills for four different
kinds of thing. Each control now draws its own quantity: effort as a five-bar
level that lights up by step and colours by cost, approvals as a ring whose gap
is how much the gate lets through (closed with a bar through it is the strictest
posture, not the loosest — its old label said the opposite of what the kernel
does), plan as an icon that strokes itself in. The effort menu carries the same
scale, so opening it shows a gradient rather than six equal words.
Floating layers get their own tokens. A menu was never transparent, but on the
dark theme --raised sits a shade from what it covers and a black shadow lands
on near-black, so the only thing separating a menu from the transcript was one
border. --float lifts the surface, --shadow-float adds a lip and a ring. Five
popovers that each carried their own shadow now share it.
The trajectory grows a timeline column: a bar placed by +t and sized by
duration, coloured by tool category. A result is written when it ends, so bars
run from at-dur to at and parallelism shows itself — a subagent's 8.4s bar with
its own calls nested inside the span.
Following: scrolling up mid-turn did nothing at all (measured: 1500px undone
before the next frame). The marker at the bottom resumed the follow on position
alone, and blocks mounting push it across that edge constantly, so every
virtualisation event yanked the reader back. Resuming now needs a downward
gesture; releasing cancels the follow already queued for the next frame.
Jitter: the reveal clock appends characters on its own rAF and the follow
scrolled on another, so the distance to the bottom swung 0-142px through every
stream. The follow moves into the layout pass, where the DOM has grown and the
frame has not been painted yet. 142px of swing becomes 24.
The composer offers four postures and the kernel has always had four, but
/tool-approval-mode carried its own copy of the list with three names on it —
so choosing "don't interrupt" answered 400. The copy had a second fault that
would have outlived the first: it lowercased the request before comparing it
to ToolApprovalDontAsk, and "dontask" never equals "dontAsk".
Validation moves behind control.ParseToolApprovalMode, so which postures exist
is answered in one place. Aliases (dont-ask, deny) canonicalise with it and an
unknown name is still a 400.
The host recognized one way to finish a turn — everything verified — so the
model that did the work, found the task self-contradictory, and said so was
reported as a failed run. On a workspace where two suites demand different
values from one pure function, that left contriving a way past the checks as
the only path the host rewarded, and a real run took it: a call counter
returning 100 the first time and 250 after.
conclude_blocked is the missing exit. The claim costs what a claim of success
costs — every citation must match a receipt from this turn, and a failed
command counts, since the run proving a task impossible is usually the one that
failed. Readiness waives exactly one thing for it: that the check passed. The
check must still have run, and nothing else about the turn is waived.
The gate it answers to was itself too weak to notice: it asked for one passing
check and never looked at the failing one beside it, so `go test; go vet` read
as verified on a red suite. A check that still stands failed now counts against
the change, folded per check so re-running one until it passes still clears it.
Two places now name the exit at the moment it is relevant rather than after the
run has ended: the readiness gap, and ask's headless fallback — which is where
a model with no answer picks between guessing and a trick. In the same scenario
that produced the call counter, the model instead completed the possible half,
declared the rest blocked, and said what decision would unblock it.
Also here, from the same run traces:
- The delivery review gate told models to run `git status --short` and
`git diff` when a change reported no paths. In a workspace that is not a
repository that instruction cannot be followed, so it now states what the
host needs — which files the change touched — and leaves the means alone.
- A headless run dropped the end-of-turn quality verdict entirely: the same
turn the chat TUI flags as partial finished silently. Both frontends now read
it from one place on the event.
`go test ./... | tail -5` exits with tail's status, so a failing suite reported
zero and the host could only call the check inconclusive — which the readiness
gate reads as "no verification ran". A project whose house rules pipe test
output could therefore never finish a turn, and the gate's own instruction
("run a relevant verification command") was false to a model that had just run
one and watched it print `ok`.
bash already knows each stage's status. For the one shape a status can be lined
up with — a single pipeline whose exit is decided after the check — the host now
appends a report of PIPESTATUS and restores the command's own exit status, so
nothing downstream sees a different result. `set -o pipefail` would have been
simpler and wrong: it changes what `| head` means.
The report never reaches the model: it is stripped from the output, the tail,
and the live progress stream, and a run that truncates or dies simply reports
nothing rather than something wrong.
Where no report is possible — `a | tail && b | tail`, where PIPESTATUS covers
only the last pipeline — the two messages now say what is true. The tool result
says so as it happens, and the gate names the command whose status belongs to a
later stage. A run that used to end in error now re-runs the check on its own
one round later.
`gofmt -l`, `prettier --check` and `eslint .` were graded as writes, because
the host could not prove them read-only and treated that as proof they wrote.
A write with no path is opaque, so one such check after an edit pushed delivery
review to its high-risk gate, whose only instruction was to name the changed
files with `git status --short` and `git diff`. In a workspace that is not a
git repository there was no way to answer, and the run ended in error with a
green suite on disk.
Mutation now carries how well the host knows it: proven — a writer tool's
contract, or an output redirect to a named file the parser found — unknown, or
none. Risk scores only proven path-less writes as opaque, since a command that
merely resists classification describes no change set a reviewer could be
pointed at. The delivery baseline takes the latest proven write and falls back
to an unproven one only when there is no proven one at all, so a check that
runs after the verification no longer moves the goalposts past it.
ToolCallMutates keeps its conservative boolean view: permission and the
delivery floors still treat unknown as a write, exactly as before.
`bash -l -i -c` sets no pipefail, so `go test ./... | head` exits 0 on a suite
that just printed three failures. Six places read that status as the check's own
answer: the host classifier, the completion report, the readiness floor,
delivery sign-off, the contract's declared checks, and the summary line. Eight
real runs produced 22 verification commands between them; only 10 carried a
status that says anything about the check.
The verdict now comes from what a zero status actually proves.
shellparse.ExitZeroImplies reads it off the AST: both sides of `&&`, only the
last stage of a pipeline, only the last of several `;` statements, neither side
of `||`, and nothing at all behind `&`. A check whose verdict the shell handed
to a later stage is recorded as inconclusive — it neither proves nor refutes, so
it counts as neither. Receipts the host never classified keep reading their own
outcome, which is all a declared command or a replayed session carries.
Two shapes this fixes, both observed live rather than imagined:
- `ls -la && go test ./... 2>&1 | head -100`, run while three tests were red,
was recorded as a verification that passed.
- `go test -v ./... | tail -20 && git status --short`, run on a green tree
outside a repository, was recorded as the suite failing.
Verification items key on the check they carry rather than on the wrapper around
it, so re-running one inside a different pipeline supersedes the earlier outcome
instead of opening a second item the fresh run never clears.
A check is also no longer discarded for its company. `go test ./... && gofmt -l
.` carries a readable verdict even though the host cannot prove gofmt leaves the
tree alone: the short-circuit is the same reasoning the admission gate already
applies when it blocks only the maskable mixed shapes. Not adding gofmt to a
read-only table was the point — ruff, prettier and eslint follow it, and the
table never ends. IsDeliveryVerificationCommand keeps the stricter question for
sign-off, where "only verification and read-only work" is what is being asked.
The summary line and the completion receipt now answer together: a contract the
ledger cannot fully vouch for is no longer summarized as complete beside a
receipt listing what stays unproven.
Recovery guidance rides the steer path under its own host prefix. A model told
the user interrupted starts answering someone who never spoke, and cannot tell
that from a real interruption.
Switching sessions felt slow, and the length of the transcript was not why:
a 12MB record reads back in 8ms. What the reader waited on was /status, which
queried the provider's wallet endpoint on every call — 87-167ms, uncached —
while the pane held the transcript behind a Promise.all with it.
Three layers, measured at each end:
- billing.Cache serves one wallet answer for 30s, lets exactly one caller
refresh it, and keeps a good reading standing in for five minutes when the
endpoint starts failing: unreachable is not empty. billing.Store shares one
cache per endpoint and credential, because opening a conversation builds a
whole runtime and a per-runtime cache is cold on exactly the read a switch
waits on. control.Options collapses its three balance fields into that one
cache, which is also what keeps boot.build under its ratchet.
- The pane reads the record and the numbers over it separately. __restore no
longer carries the cache totals; __totals brings them when they arrive, so
they are still read back from the kernel rather than restarted at zero.
- fromHistory drops two O(n²) shapes — a linear search per tool result, and a
full copy of the folded list per item. 3200 turns: 121.6ms to 2.9ms.
/status 100ms to 15ms; transcript on screen 139-219ms to 48-125ms, and no
longer a function of how long the conversation is. perf/switch.mjs is the
bench that holds it, with PERF_STATUS_MS to separate the two waits.
Carries the rest of the in-progress studio work in the same snapshot.
/shell is registered on the kernel but was missing from the window's api-path
allow-list, so the request fell through to the static assets and answered
index.html. The pane read that as a failure and said 读不到 shell 配置 — a
routing miss wearing the costume of a broken kernel.
TestEveryRouteTheKernelRegistersIsRouted guards exactly this and catches it when
reverted; it went unrun because desktop is a nested module that a test sweep over
./internal/... never reaches.
Two things the workbench could describe but not act on.
An extension that publishes a view against a tool call now draws inside that
call's card. The takeover replaces the body only: the name, the status, the cost
and the failure line stay the host's, so a redrawn card is still recognisably
this call and still visibly the extension's work. The surface travels as a
first-class DTO through eventwire and uihub rather than as an opaque blob.
The shell tool's interpreter becomes a setting. It was already auto-detected —
real bash first, Git for Windows next, PowerShell only when a Windows host has
no bash — but nothing in the new UI said which one was chosen, and nothing could
change it. sandbox now exposes what auto-detection picks from (DetectShells) and
whether a chosen one actually runs (VerifyShell); the settings pane offers only
interpreters this machine really has, names what "自动" resolves to here, and
says on the row itself that Windows PowerShell 5.1 will not parse '&&'. Choosing
one persists to [tools.shell] and rebuilds the runtime, because boot binds the
interpreter into the tool while assembling it — the same path a role assignment
takes, and refused mid-turn for the same reason.
A shell card spends its mono tag on the interpreter instead of on the tool id:
the name above already says Bash, and on a host without one the command was
handed to PowerShell, which is the difference between a command that works and
the same text failing on '&&'.
The first launch asked for "deepseek 的 API key" because refreshProviderSetup
resolves the provider from the current default model, and the default is
DeepSeek. Anyone on another service had nowhere to start.
The connection step now asks the two things only the user knows — where and
with what — and lets probeProvider answer the rest. The shortcut row fills the
address and nothing else, so a service missing from it is not unsupported;
what decides that is what the endpoint replies. 中转站 / 自建 sits in the same
row rather than under a fallback, because a relay is what many people have.
A failed probe shows the endpoint's own words: 401, a wrong path and "no chat
models" send the user to three different fixes.
Before it, a sequence that plays once per machine: aurora drifting on a fixed
dark ground, the R drawn and then traced by a light, the wordmark swept by a
highlight, and three lines that say what the thing does. It does not cut to
the form — the whole group collapses into the card's header, so the brand
never leaves the screen. The progress line and the skip hint leave with it;
kept on screen beside an input they would read as "still loading".
The ground stays dark whatever the app theme is: this is a ceremony, not a
screen of the app. Any key or click skips it, reduced-motion goes straight to
the end, and a machine that already has a key gets the short cut of it.
[desktop] welcomed carries the once-only state. Browser storage would replay
the introduction whenever a cache was cleared, which reads as a bug rather
than a greeting.
A relay that does not know thinking or reasoning_effort rejects every request
that carries them, and its error rarely names the field - so the failure reads
as a broken key or a wrong path. reasoning_protocol="none" already produced
the plain-chat shape; nothing surfaced it.
The account card now carries the switch beside 联网搜索, in the two positions
a user actually has: 自动, or 不发送. Releasing it clears only that pin, so an
explicit deepseek/glm/kimi-k3 choice survives. Protocols whose wire has no
such field never offer the switch.
Three defects found by running the real DeepSeek API behind a recording proxy
and reading the trajectories.
A tool-call turn with no reasoning was treated as a lost field and answered
with one exact replay of the whole frozen request. Every run triggered it,
and on a long-context turn it re-sent 29k prompt tokens to recover five
reasoning tokens. Billed thinking tokens with no text mean the value really
was lost in transit; zero billed tokens mean the model stayed silent, which
is ordinary between tool calls. The classifier now separates them, and the
exclusive reasoningObservation states replace a (missing, shouldRetry) pair
that could spell 'not missing but replay it'.
Optional sink capabilities are delivered by type assertion, so CostQuoteSink
- which forwarded Emit alone - silently dropped all ten audit channels one
link before the trajectory recorder. Trajectories recorded zero audits while
the code faithfully emitted them. capabilityContracts is now the single
authority on the set, FanOut forwards them across the split, and the three
hand-written forwarders get the RunBudget channel they had all missed.
update_goal is unreachable in a headless run, yet its 2.2k-char schema shipped
every turn and the model duly called it and was refused. Whole-session
unavailability can leave the schema without churning the cache prefix; only
per-phase visibility must not. GoalTurnsUnreachable draws that line.
A turn that took more than one request billed the sum while its context was
only the last request's, and the input column showed the sum with no hint.
Measured on the same task before and after: 12 rounds instead of 14, 51.4s
instead of 58.8s, zero wasted tokens instead of 29,085, and 14 audit records
where there had been none.
Working snapshot of the studio branch: installable plugin packages (plan
ticket, archive, export, install-source permission subject), the extension
protocol's view/slot rendering path, desktop theme tokens, and the file-drop
surface on the next shell.
Grouped as one commit because the pieces share the generated protocol schema
and the desktop port they land through.
macOS reads a Dock icon out of the app bundle, and the shell also runs as a
bare `go build ./next` binary with no bundle around it — so it carries the
artwork itself, the counterpart to the committed .syso that brands Windows.
The copy lives in the package because go:embed cannot reach out of it; a test
pins it to build/darwin/icon.icns, which is the one the safe-area guard reads.
The theme picker asks for /themes/{id}/preview and /themes/{id}/background.
Neither was in the shell's route table, so both answered index.html and every
pack rendered as a broken image. /inbox fell through the same gap.
The existing guard could not have caught it: it scans the typed client, and
these two URLs are written straight into an <img src> and a CSS url(). The new
one reads internal/serve's own registrations back instead, which covers both
kinds of caller. Fixing the old scanner too — it read "/export" out of a
concatenated /plugins/{name}/export, a request no one makes.
Colours were only half of what a pack is. The eight that ship each carry a
background and a thumbnail, and the manifest field describing them was being
read past — so "install a theme" meant a palette swap and nothing else.
The image is not just an image. A pack says where its subject sits (focusX/Y,
so a portrait survives a wide window), which side the content is on
(safeArea), and — the part worth having — how far the picture recedes once
work starts: the shipped packs sit near 0.95 idle and 0.18 while a turn runs.
A photo that is right behind an empty window is in the way of a transcript
being read, and the old shell had already worked that out.
Drawing it takes two fixed layers under everything and a scrim of the page
colour over the top, so text keeps its contrast whatever the photograph is
doing. The block is inert until a pack sets --bg-image: a default build paints
no extra pixels. Only the empty page shows it through — cards, panels, and the
composer stay opaque, because a background is worth a window's margins, not
its content.
Assets are served by id, and the id arrives as a URL segment, so what can be
read is bounded twice: the id must be a bare name, and the filename is always
<kind>.<known extension> beside the manifest. A pack cannot name a path.
1.8MB of webp joins the binary. That is the eight palettes being complete
rather than a format with no example of itself — and the thumbnails are what
let the picker show a photo-backed palette as one, before it is applied.
The Wails shell keeps its own list of which paths are the kernel's and which
are the bundle's, so an endpoint that exists in serve but not in that list
answers with the SPA shell — JSON parses as HTML and the caller sees a broken
feature rather than a missing route. /themes and /extensions/* were added on
the serve side without it. TestEveryPathTheFrontendCallsIsRouted is what
catches this, and it was red.
/extensions goes in the prefix list, not the exact one: action and submit hang
off it the way /mcp/reconnect hangs off /mcp.
The themes_test rows get a name while passing through — the same anonymous
struct was written out three times to give the lookup helper a signature.
The composer parsed its own grammar, so the window's "@" meant something the
kernel had never agreed to — it had no way to read a directory at all — and "/"
listed only skills and custom commands, hiding every built-in the Submit path
already dispatches. control.Complete now answers all three menus: which token
the caret sits in, what may replace it, and the span to replace. The CLI reads
it too, so the terminal and the window cannot drift apart. serve exposes it as
GET /complete and converts the kernel's byte offsets to the UTF-16 units a
browser indexes by, which is what a Chinese prompt needs to splice correctly.
Fixes the work surfaced:
- a hand-typed /compact with nothing left to fold reported the provider limit;
manual carries Force, and the no-fold branch read Force as overflow
- every notice-only verb answered 409, because serve judged a submission by
whether a turn had started and a management verb starts none
- reopening a session showed the composed text, so a one-line @reference came
back as the whole file it referenced
- the window had no Edit menu, so a WKWebView had no copy, paste, or undo
- an input method's confirming Enter sent the half-written message
- cancellation during a fold was recorded as a summary failure
- internal/agent's test package did not compile, hiding both of the above
The tree carried other unlanded studio work in the same files — attachments,
changes, checkpoints, rewind, themes, extension surfaces — and file granularity
could not separate it, so it lands here as well. desktop/next's route list
still omits /themes and /extensions/*, so its routing test stays red; that
belongs to the extension work, not to this.
99ef4b2f0 removed ContextMaintenanceReceipt.Archive and updated the old
shell's TypeScript mirror, but not its Go side. desktop is a separate module,
so the main module's build never saw it: `go build ./...` at the repo root
passes while the desktop module does not compile at all.
Three finished files were never added, and the commits that use them went in
without them. On any clean checkout — CI, a fresh worktree, another machine —
the module does not build:
eventwire/wire.go calls e.Tool.ContextTokens(), defined in
event/tool_cost.go, which imports internal/tokencount
state/session.ts uses sample() and outWindow, from port/tokens.ts
Local builds pass because the files are sitting in the working tree, which is
exactly why this survived several commits.
They are complete as they stand: tokencount carries a package comment and a
test, and its by-script split is the fix for the estimator that read ASCII as
four times its real cost. Nothing here is new work — this is the add that
should have ridden along.
The frontend still does not typecheck after this: SsePort is missing changes
and attach, which port.ts declares. That is in-progress work, not a missing
add, so it stays where it is.
studio's palette was compiled in: tokens.css held one light set and one dark
set, and nothing could change them without a rebuild. The old shell has had
theme packs for a while — a directory with a theme.json, colours only — so the
format already exists and eight of them ship. What was missing is a reader that
does not live inside the old shell, and endpoints for the new one.
internal/theme reads packs from <memory root>/themes. Two things it refuses:
- a pack from a schema it does not know is skipped rather than half-read,
and one bad pack cannot hide the rest of the list
- a token that is not a plain hex colour is dropped, not escaped. The value
ends up interpolated into a stylesheet by whoever renders it, so url(),
an expression, or a stray brace never reaches that point
GET /themes carries every pack's whole token set, not just the active one's:
a picker that must fetch before it can preview cannot preview on hover, and
the payload is a few hundred colours. POST /themes activates one, and an empty
id is a real choice — it is how a user turns a pack off.
The frontend half (in progress separately) maps a pack's names onto its own
variables and paints them at runtime. What a pack may not touch is fixed
there: ok/warn/err/net/deleg encode what is happening — "this broke", "this is
running" — and a theme that could recolour them would let a failure render as
success. The palette is the theme's; the meanings stay the app's.
Adding one config field turned out to need the renderer too: RenderTOMLForScope
writes the file field by field, so a struct field it does not know about is
silently never persisted. The [desktop] table moves into its own function and
file on the way past — it was the longest run in a 777-line function, and
DesktopConfig follows into its own file, which puts both back under the size
ceiling instead of one line over it.
An extension could publish a card, a form, a notification, a status line —
every one of them a thing that happens and then scrolls away. What it could not
do is describe something that is still true: a watcher running, a sync at 40%,
a connection holding. That state belongs in the side rail, and there was no
surface kind for it.
UISurfacePanel is that kind, and it is a kind rather than a new RPC on purpose.
The method registry is frozen; growing it per feature is what turns version
compatibility into every extension author's problem. A new surface travels the
publish path that already exists, so an extension built against an older host
degrades to an unknown kind instead of a broken call.
UIPanelPayload carries no Markdown, unlike UICardPayload. The rail is a narrow
column and a rendered document there costs the layout more than it tells the
reader; an extension with a long story to tell publishes a card into the
transcript, which is what the transcript is for.
Registering the kind is what actually admits it: protocol.enumTypes is the one
table the strict decoder, the JSON Schema, and the generated SDK all read. The
generator's own guard caught the rest — a surface kind with no matching
UI<Kind>Payload in the SDK fails generation loudly, which is how it should
have gone. Regenerated artifacts follow, schema hash included.
The Extension* types move out of event.go and eventwire/wire.go into their own
files while passing through: both were already over the size ceiling, a new
surface kind touches every one of those structs, and the two conversion blocks
are the only thing in eventwire that is not a one-liner.
Extension surfaces already reach every frontend on the event stream, but the
user's half of the exchange — invoking an action a card offers, submitting a
form an extension published — needs endpoints, and serve had none. uihub's
consumers were boot, cli, acp, and control; the HTTP surface the new desktop
runs on was the one place a plugin could talk to a user but not be answered.
Controller already exposed what this needs. Two of the three were on
SessionAPI; SubmitExtensionForm was written for "stage-8b frontends" and had no
caller anywhere, so it joins the port alongside the two it belongs with.
Three routes, in the shape the other feature files here use:
GET /extensions/actions the handshake-declared actions, empty when no
runtime is up — a state, not a failure
POST /extensions/action invoke one, answering with the extension's own
(hub-redacted) message
POST /extensions/submit a published form's values, types intact
A declined action answers 422 with the extension's reason rather than a 500:
the extension refusing is its answer, and the caller should show it. Form
values keep their JSON types because the extension declared the field kinds
and decodes against them — a confirm stays a bool, a number stays a number.
The studio side (renderer, event wiring, port methods) sits on top of
frontend-next work that is still in progress, so it lands separately.
GET /sessions read the directory itself and called agent.SessionPreview on each
file, which decodes the whole transcript to count user turns. Studio's session
list is O(sessions x transcript size) on every refresh, and it recomputes from
scratch each time.
agent.ListSessions exists for exactly this and says so: "It never decodes a
transcript." The sidecars it reads were introduced to fix this same load in the
old shell's sidebar; the HTTP endpoint the new one runs on never picked them up.
Behaviour moves onto that shared path, which changes three things, all toward
what the other listers already do:
- order is by last activity instead of reverse filename
- a session with no user turn stops appearing (it has no title and no count;
it was rendering as an empty row)
- a legacy session whose sidecar has no counts yet shows the "History is being
indexed" placeholder until the catalog's repair worker validates it
The subagent-name filter stays here: IsVisibleSession deliberately does not
fold it in, because GC and redaction still have to see those files.
The new test corrupts both transcripts after saving and asserts the endpoint
still reports 1 and 2 turns — a reader that parses transcripts cannot pass it.
HandlerWithCORS has no caller. Its own doc says "Do NOT use in production — the
server has no auth", which makes an exported, unused, security-sensitive entry
point the worst kind to leave lying around: the next person wiring a dev
frontend finds it before they find the reason it is wrong.
Neither frontend needs it. frontend-next proxies through its own origin
(vite.config.ts says so explicitly: "The dev server is cross-origin to serve,
which its CSRF guard rejects"), and the old Wails shell serves same-origin.
It was also already inconsistent with the routes: Access-Control-Allow-Methods
listed GET, POST, OPTIONS while inbox has served PATCH and DELETE since it was
added, so anything that did opt in would have been blocked by preflight on the
endpoints it most needed.
Deleting it leaves same-origin as the single stated protection for
unauthenticated endpoints, which is what the csrfGuard comment already assumes.
A turn where the provider ran its own web_search left the session permanently
unusable: every following turn failed with the same numbers and never
recovered. Reproduced with a real key against a 20K window — turn 2 searched,
turn 3 onward died on "candidate would not reduce tokens".
The cause was not compaction. DeepSeek bills its fetched pages as input
(usage.server_tool_use.web_search_requests says how many searches ran, a field
wireUsage was dropping), so PromptTokens on such a turn counts content that
never passed through us. Learning the chars-to-tokens ratio from it inflated
every later estimate by roughly 3x, which read as overflow, asked for a fold
that cannot shrink what we never held, and refused the turn — and a refused
turn sends no request, so the observation never updated and the next turn
decided identically.
Three changes. Usage now carries ServerToolRequests and the calibration
declines to learn from a turn that has any. Where a failed fold would strand
the turn, a transcript that fits under the ceiling is sent anyway and the
provider rules. And oversize tool output goes to <session>.outputs/ with the
context keeping a pointer plus twenty head lines, because a head+tail sketch is
a guess about which part mattered made by the wrong party — read_file windows
the file and grep searches it. That threshold is window-relative: a fixed 32KB
is a rounding error in a 1M window and larger than a 20K one. Windows at or
above ~128K keep 32KB exactly.
Verified end to end on the same sequence that died: six turns, no failure, and
context tracking our own transcript (6.8K) rather than the provider's billed
input (27K). A 728KB bash result reached the model as 581 characters, which it
read correctly as "120001 lines, 712 KB, saved to a file, not lost".
AssessRuntimeResume and ResumeNotesForGeneration wrap extension.DecideResume
and format "doctor-facing notes". No doctor calls them; nothing outside
recovery_test does. boot/doctor_runtime.go, the real doctor path, calls
extension.DecideResume directly and formats its own report — so this was a
second formatter for a decision the actual caller already reaches without it.
Removing them also drops recovery's only direct import of internal/extension.
internal/capdiag imported internal/boot for exactly one call —
PluginSpecsForRoot — which made it the repo's only layering violation, carried
in the repolint baseline. capdiag is a diagnostic: it describes configured MCP
servers, it does not assemble a runtime. The rule it broke ("nothing below a
frontend may import one") was right; the placement was wrong.
Turning configured entries into plugin.Spec is a pure mapping over config,
plugin, sandbox, and mcplaunch — every one of them below boot. It sat in the
assembly layer because that was the first caller, not because it belonged
there. internal/pluginspec now owns it, and boot, cli, capdiag, and desktop all
reach the same function at a level each of them may legitimately import.
boot keeps what is genuinely assembly: partitionByTier reads a startup policy,
skillMCPBindings needs the live tool registry. Its pluginspec.go drops from 230
lines to 60. The mapping tests move with the code they cover.
appendUniquePaths and pathComparisonKey are copied verbatim rather than
simplified: they compare paths by cleaned, absolute, symlink-resolved,
case-folded-on-Windows form, and a shorter version would silently change which
sandbox roots dedupe.
The baseline loses its layering entry and the limit goes to 0, so the next
violation of this rule fails CI instead of joining a tolerated list.
Auto recovery and the guardian each stopped the turn on a count. Recovery's
was 3 failures of one operation, 6 per Episode, 3 reviewer rejects, 3 retries
of an already-stopped operation; the guardian's was 3 consecutive denials or
10 in the last 50. Both then interrupted: recovery burned a summarize-only
round and returned "Automatic retries paused. Send continue to start a fresh
attempt", the guardian injected "stop the current approach and request
explicit instructions".
Neither number came from the user, and neither measured what it claimed. Six
failures is a long debugging session in one codebase and a runaway in another.
The reviewer rejecting three proposals means the reviewer disagreed three
times, not that the work is unrecoverable. What the host actually did with
those counts was take the turn away and ask the user to type "continue" —
which is the user's decision arriving as a chore.
What survives is the part that reads the proposal in front of it: Decide still
routes an ordinary mutation to allow and an ambiguous retry of the same failed
operation to the reviewer, and the reviewer's own reject still blocks that call
with its rationale. A repeat now goes back to the reviewer instead of hitting a
ceiling. The guardian still denies, still forces deny on critical risk and on
high risk without authorization; it just no longer stops the turn on top of
that verdict.
Per-operation failure counts stay — the reviewer and the approval card read
them as evidence ("this exact call has failed N times"). They no longer arm
anything.
With this, RouteStop/RouteStopTurn, the Episode budget, StopReason,
RecoveryPauseError, and the finalization round it drove have no producer, so
they go. event.TurnOutcomeRecoveryPaused stays readable: sessions recorded
before this still carry it.
Nothing else bounds a turn by default (agent MaxSteps is 0 unless the user sets
one), so an Auto run that keeps failing now keeps consulting the reviewer until
the user interrupts it. That is the intended trade.
Ten declaration comments still describe a three-setting product ("light|
balanced|delivery", "all three role settings") that one setting left, and two
describe an injection that no longer happens: DeliveryRuntimeMarker's doc says
the agent appends it to user turns and calls its text cache-frozen for every
live delivery session, twelve lines above the code that stopped appending it.
A comment that names a mechanism is a claim the reader cannot check without
reading the whole path. Both of these sent the reader looking for a caller
that is not there.
Three word lists decided which capabilities got a prefer in the turn's route
block. looksLikeReview matched 审查/有没有问题 and hardcoded the built-in named
"review". looksLikeGitHub promoted every tool of any server whose name contains
"github" when the sentence said "issue" or " pr ". looksFreshData promoted any
search/fetch/read tool when it said 最新 or 查一下 — a list that also contains
"github", so a sentence naming the vendor scored twice.
Those are guesses about intent, and a prefer is not free: it takes one of five
route slots and tells the model to use the capability unless clearly
unnecessary. "查一下 GitHub issue 里有没有相关反馈" spent slots on every github
tool before anything read the request.
What stays is what someone actually stated: the user naming a skill or an MCP
server, and triggers the skill's own author declared in frontmatter. When
neither fires, the decision belongs to the semantic router, which reads the
whole request instead of a word list.
NeedsFreshData goes with them — it was parsed from needs-fresh-data, carried
through skill.Skill into capability.Entry, set by one built-in, and read by no
decision anywhere. negativeMatch was triggerMatch under another name.
When the keyword risk table retired, Risk kept its three levels and lost every
input: HighRiskHints and MediumRiskHints are set by tests and by nothing else,
and RaiseRisk has no production caller. Derive has answered RiskLow for every
turn since. Two gates read that constant and both failed open.
Explore: AllowExploreSubagent is `preset && risk > RiskLow`, so it was false
under both role settings, and taskPolicyToolGate blocked every explore/research
call with "the current task policy does not allow proactive explore/research
sub-agents for this turn." The setting that was supposed to permit them said
true the whole time.
Review: Review is ReviewForRisk(low) = ReviewNone under both settings, and
deliveryReviewGateFailure opens with `case ReviewNone: return ""`. Delivery's
stated contract — review on medium-risk mutations, security_review on high —
never ran. Its tests pass because they build an Agent whose policySet is false,
which is the one state a real turn never has.
So risk goes, and MutationRiskAfter stays: what a change owes is read off the
receipts it produced, which is the only source that ever knew. Route follows —
it had no reader outside the policy block, planner routing having moved to
"did the user ask for a plan". SemanticRouterAllowed follows; Delivery decides
the router directly, which is what the non-planner path already did.
RequireFullVerification goes too — parseConstraints never set it.
The new capability_gate case freezes a real Derive policy before calling the
gate, so the next constant that closes it fails a test instead of a release.
Verification block drops from four fields to one; PolicyVersion bumps to 2.
Compaction receipts carried an Archive field, the wire carried it, and both
frontends rendered it — the CLI as "archived <path>", the desktop card as
"，原件留在 …". Nothing has assigned it since summary checkpoints replaced
archiving: canonical keeps the originals, so there is no second copy to name.
Every reader was reading the empty string.
Four tests asserted it stays empty. They passed against a field that could
not be anything else, which is the shape a guard takes once what it guarded
is gone.
Deleting the light setting exposed the chain behind it. SkillEntriesFiltered
opened with `_ = profile`: it took the runtime profile and threw it away, so
the name promised a filter to every reader of the catalog. FilterForProfile
had no callers at all, AllowedInProfile had only that one, and the Store field
those fed — runtimeProfile — was written on every boot and read nowhere.
So the whole path existed to carry a value to a function that discarded it.
It is gone: skillCatalogEntries says what it does (skill entries plus the
frontmatter a reader sees), and boot no longer threads a profile through skill
assembly to reach it.
capability.Profile stays. Its constants are still the allowed-value list for
normalizeProfiles, and controller keeps it as a diagnostics label — but the
type and the CatalogOptions field now say they select nothing, because a name
that claims to filter is how this got missed for so long.
A skill's `profiles:` frontmatter is unaffected: it parses, it is reported,
and it has not hidden a skill from the model for some time.
"不是省钱档位" answered a question nobody asks now that light is gone, and
"规划深度"/"按复杂度自适应" described the planner route — the one dimension
that only ever reaches the model as a line of prompt text, with nothing in the
host to enforce it.
What separates the two settings is who decides a turn is finished: the model,
or the host reading its own receipts. The copy says that now, and delivery
lists the four things it checks instead of naming our internal term for them.
These tests used "economy" as "switch to something other than the default"
— for the tab profile, the persisted session profile, the rebuild event, the
in-place switch guards. It resolves to the default now, so the calls became
no-ops: nothing was saved, and the guards that fire on a real change never
fired. Delivery is the setting that is still different.
The desktop module is not built by the root module's ./..., which is why
these missed the earlier sweep.
The title bar's switcher carries its own PRESETS list, separate from the one
in settings, and it still offered 轻量. Sending it was harmless — the kernel
resolves the name to balanced — but the button's pressed state compares
against what the kernel stored, so it could never light up: clicking it looked
like nothing happened.
Two problems. A machine with no git could not install a plugin at all —
`git clone --depth=1` was the only path to a GitHub source. And on macOS a
machine without the command line tools claimed it *had* git: /usr/bin/git
is an Xcode stub that resolves on PATH and fails only when run, so the
LookPath check guarding worktree isolation read as "installed".
gitcmd.Available runs git rather than finding it, and the worktree lease
asks it. It is uncached on purpose: every caller is a low-frequency
decision, and caching the "no" would make installing git afterwards
require a restart.
A plugin source falls back to the GitHub tarball when git is absent. The
commit the approval contract pins comes from the archive root, so apply
still cannot swap in a tree the user never reviewed. The unpacker drops
symlinks — a link may point outside the tree — refuses entries that escape
the root, bounds each entry and the total against a bomb, and skips the
pax_global_header GitHub writes first, which the first draft mistook for
the archive root until a test said otherwise.
doctor gains a git section stating the absence as a fact and naming what
degrades (the changes list, worktree isolation) while saying rewind,
checkpoints and every tool keep working. Nothing else in the kernel touches
git: agent, control and tool have no reference to it, and checkpoints were
already git-free by design.
The role settings declared far more strategy than they enforced. Six fields
had no reader anywhere — RequireAtomicContract, SemanticRouterOnAmbiguity,
DeterministicFirst, PreferProxy, DiffReview, AllowPartialWithoutChecks —
including two that were the stated difference between delivery and balanced.
A policy table that names a contract nothing builds is worse than a smaller
one: it tells the next reader a guarantee exists.
Light goes with them. Against balanced its only enforced differences were two
sub-agent switches (explore agents, semantic capability routing); the things
its name promised — cheaper verification, lighter review — were identical
settings on both. Its high-risk elevation moves to balanced so no user's floor
drops, and its capability profile selected an economy catalog that
SkillEntriesFiltered discards on its first line.
That leaves one question for the user instead of two: default, or delivery —
where the host enforces acceptance criteria, sign-off, verification, and
review off its own receipts.
"light", "economy", "eco", "lite" all still parse and answer balanced, so an
existing config or an older client is never rejected. They no longer pass
IsValid: they resolve, but nothing writes them back out.
A turn that ends owing verification has not failed. The host read what is
missing off its own receipts — not off anything the model claimed — and then
stopped to show a card whose only action was "continue". That asked the user
to relay a message the host had already written.
Goal mode has auto-continued on exactly this signal all along; the difference
was a goal being set. It no longer is: an ordinary turn that ends with unmet
requirements runs them as further turns, with the missing list as the prompt.
Nothing new judges intent — readiness is the same host-computed check, and a
turn that changed nothing owes nothing, so questions and reads still end in
one turn.
What bounds it is the gap itself. Each round is admitted only while the list
of missing requirements is still shrinking, measured against the best round so
far so an oscillating gap cannot reset the counter. Two rounds that owe what
the last one owed hand the turn back, card and all.
The continuation inherits the finished turn's ledger through the same
authorization the recovery card used. Without it the next run would start
empty, where a turn that owed verification owes nothing — the gap would read
as closed because the record of it was dropped, which is worse than not
continuing at all.
PrepareReadinessContinuation lands in final_readiness.go rather than agent.go,
which is over its size budget.
DeepSeek's Anthropic face runs web_search on its own side, and its results
were formatted straight into the answer text. Forty titles and URLs pushed
the actual answer off the screen, and no tool card ever existed — the
spec's Search card had nothing to draw from.
Results now leave the provider as ChunkProviderTool, the query paired with
the listing that answered it, and the agent reports one finished
ToolResult. Result only, no dispatch: the call arrives finished, and a
dispatch is the one event deferredStreamSink holds back, so it would land
after its own result and never settle the card. The listing still joins
the turn's text — the only copy the next turn has, because the provider
keeps the result bodies encrypted — so request bytes are unchanged and the
prefix stays cache-stable.
web_search moves into its own file and Chunk out of provider.go, which
pays back the file-size, function-size and essay budgets the two new
stream branches would otherwise widen. The baseline carries only their
complexity: 45 to 47.
Controller.Send has always run its turn through runGoalLoop, and the name
made a goal sound like a precondition for sending a message. It is the other
way round: every ordinary message takes this path, and the Goal FSM answers
"do not continue" the moment it sees no active goal — one nil check, then the
turn ends like any other.
Reading Send meant learning the goal subsystem first to find out it was not
involved. runTurnLoop says what happens, and two doc comments say where the
goal actually enters: after the turn, as the thing that may ask for another.
Pure rename plus those comments; no behaviour change.
internal/autoresearch was a read-only compatibility boundary for Goal
sidecars naming a pre-unification .reasonix/autoresearch task. Its own doc
comment says new Goal runs never create, update, list, or expose those
archives — and searching the filesystem finds no archive to read: the
package and the machinery around it served zero files.
What went with it is everything that existed to keep such an archive
recoverable: the fail-closed restore path (a blocked Goal that could only be
unblocked through the archive boundary), its retry token on Controller, the
legacy-archive stop cause, and the FSM's pending-migration task identity.
SetGoal collapses to what it always did for every real goal — install the
text — since the archive was the only thing that could rewrite it.
One field stays: goalState.AutoResearchTaskID is now read-only migration
detection. A sidecar still naming a retired archive is rewritten as ordinary
Goal state on first write, which is how the last of them disappear.
The <autoresearch-evidence> stripping in agent/goal_display.go is unrelated
and stays: it scrubs a historical protocol marker out of model output, not
storage.
Net: 1799 lines of package and manager, plus ~250 of restore machinery.
The card said "正在压缩…" and nothing else for as long as the summarizer
took, which on a large fold is a minute of a placeholder that cannot be told
apart from a hang. The digest now streams onto the card as it is written.
It accumulates on the card's own summary, so the finished event replaces it
rather than fighting it — and a fold that dies mid-write leaves what it had
written instead of an empty placeholder. Only the newest line is shown: a
digest is thousands of tokens of headings and lists, and growing the card by
all of them would move everything below it for the length of the fold.
POST /model rebuilt the running controller and wrote nothing, so the choice
lasted exactly as long as the process. The next launch read default_model and
went back to whatever was there before — switching to an account's Anthropic
door and finding it on OpenAI again after a restart, with no sign the switch
had ever worked.
The CLI has persisted its /model since it had one, and the old desktop's picker
sets the config default alongside the live switch. Serve was the entry point
that did not, which is every studio window.
A refused write is logged and nothing more: the live switch already succeeded,
so failing the request would report the model unchanged when it had changed. A
ref that resolves to nothing leaves the existing default alone rather than
writing a value the next launch cannot start from.
Cache-impact: none - the prompt prefix is untouched; this writes default_model
to the user config after a switch that already happened.
Cache-guard: not applicable; no provider-visible bytes change.
Documentation-impact: none - no docs/*.md states whether the desktop model
picker persists, and it now matches the CLI's documented /model behaviour.
A fold holds the turn for as long as the summarizer takes, and all the user
had was a placeholder that says the same thing at second one and second
ninety. The text was already streaming — summarize consumed provider chunks
into a builder and forwarded none of them.
CompactionProgress carries each chunk on Event.Text, which is what lets the
existing coalescer merge it: it treats an event as a stream delta when only
Text carries meaning, so the digest batches at 16ms like reasoning does
rather than spending a frame per token.
The CLI shows the newest line of the digest on the "compacting…" line itself,
bounded, and replaces it with the finished card. Only the tail: a digest is
thousands of tokens and the card is about to render it anyway.
The three compaction cases fold into one handler, which takes 19 lines and
two branches out of chatTUI.update and lands them in a file that is about
compaction.
Repolint baseline: mostly tightened by today's work (complexity 2058→1994,
essays and function sizes down with it). One entry loosens — desktop's
types.ts gains the line for the new wire kind, which the shared-kind guard
requires and which no local edit can offset in a 2328-line type file.
The picker was models.map with the config entry's name as the subtitle, so a
DeepSeek account reached under two protocols listed four rows that all said
deepseek. Which one was the Anthropic route was not on screen anywhere, and
that route is the one carrying web search.
Rows now sit under the account they belong to — host beside the name, because
the name is the config's word for an entry and two doors share it — and carry
the protocol that reaches them. Both labels appear only where they resolve
something: one source with one door stays a plain list of models, and the
account caption is omitted entirely rather than stating the obvious.
Menu grows a header item for it. plain was the closest thing available and it
is still a button, so a caption would have taken focus and made the list twice

The kernel started reporting a compaction's sizes and coverage; this is the
card reading them. A digest reads as finished whatever it dropped, so the
count of the fold's changes it carried is the one thing the card can say that
the summary text cannot — and it is stated whether or not anything is
missing, because a number that only appears on failure is a number nobody
learns to read.
The bar and the checklist are the .comp-bar / .comp-l the stylesheet has
carried all along with nothing to fill them. The bar's fill is what the fold
gave back rather than what it kept: the fill is the ok colour, so more of it
has to mean more room.
An older event carries none of these fields and renders exactly as before.
DeepSeek runs a server-side web search on its Anthropic and Responses wires and
not on chat completions, so one account answers differently through each of its
doors. Switching 接入方式 could take the capability away with nothing on screen
about it — a silent downgrade dressed as plumbing.
The door that has it says so, on itself. Picking the other one explains that the
difference is the protocol rather than a setting, because nothing in the panel
can turn it on there. Where a door does carry one, its tri-state gets a switch:
official DeepSeek endpoints default it on and a compatible third party stays
opt-in, so the effective answer is worth showing rather than inferring.
This is the argument for a connection-level 接入方式 in the first place. The
doors are not interchangeable transports; which one is open decides what the
agent can do, and that belongs where the account is configured, not hidden per
model row.
Documentation-impact: none - no docs/*.md describes the settings pane's
connection controls or which wires carry a provider-executed search.
A projection is valid only while the canonical prefix it folded is unchanged,
and the check for that fingerprints every message behind the fold. It ran on
every read of the model-visible view — the turn's prompt, the status gauge,
the compaction check — so the cost of one turn tracked the whole history
rather than the projection, which is the thing compaction exists to bound.
On a 40k-message transcript, measured:
modelVisibleMessages 41.8ms → 0.80ms 83MB → 14MB per call
ContextUsedTokens 1.42ms → 0.015ms
prompt assembly 41.1ms → 1.02ms
The transcript grows append-only, so a folded prefix can change in exactly
one way: a rewrite. The fingerprint is now remembered under the rewrite
counter it was taken with, passed in from the snapshot rather than read
fresh, so a rewrite landing between the snapshot and the check misses the
memo instead of silently validating it. A new conversation clears it — the
counter restarts, and a carried entry could answer for history this session
never had.
What remains linear is the snapshot copy itself (14MB), which is a slice of
headers, not a re-serialisation.
CanConfigureVision returns false for DeepSeek's official host, and
EffectiveVision short-circuits on it, so no vision_models list, provider flag or
per-model override can turn image input on there — their API takes text content
only. The editor offered the toggle anyway: it wrote the config, the config was
ignored, and nothing on screen said why.
The list reports whether the endpoint can be configured for images at all, and
the toggle goes flat where it cannot, with the reason on the row. A switch that
writes a value nothing reads is worse than no switch.
The re-probe button also said only "重新探测模型", which describes the
mechanism and not the occasion. It now says what it is for: asking the endpoint
again for its model list, after it has added or dropped one.
Documentation-impact: none - no docs/*.md describes the source editor's controls.
The connection list groups on host and credential, so two entries only read as
one account when they share a key slot. providerKeyEnv derives that slot from
the entry's name, which meant adding the same endpoint under the other protocol
produced DEEPSEEK_ANTHROPIC_API_KEY beside DEEPSEEK_API_KEY: two accounts, one
of them with no key at all. The 接入方式 switch could never appear for anything
the panel itself had added.
A blank key at a host that already has one now inherits that slot. Blank is the
signal because it is already the panel's word for "keep what is stored", and it
distinguishes the two things a second entry at one host can be: another door
onto the account, or a different account there — two tenants of one relay, where
sharing the slot would overwrite the first tenant's key. A supplied key keeps
its own slot for exactly that reason.
The form says which one it is about to do, rather than leaving the user to infer
it from whether a field is empty.
Documentation-impact: none - no docs/*.md describes how api_key_env is chosen

Coverage has been measured on every fold since it became an acceptance
criterion, and it went to telemetry and nowhere else. The user saw a digest,
and a digest reads as complete whatever it dropped — the one thing its text
cannot tell you is what is missing from it.
CompactionDone now carries the sizes and the coverage counts, and the card
renders them: "128.0K → 31.2K · 10/12 changes kept (repaired)". A fold with
nothing to carry prints no quality line rather than a hollow 0/0.
The card moves out of chat_tui.go into its own file on the way past.
Approving a tool left the run strip reading 等你批准 for as long as the tool
then took. A 42-second OCR command spent all of it claiming to be waiting on
the user, which is the one line watched to know anything is happening at all.
The decision now hands the label back to the tool it released.
Re-probing a saved source sent the key field, which is deliberately blank when
the user is not changing it, so it probed as a provider with no credential and
failed before reaching the host:
fetch models: provider "probe" has no API key (set in .env)
A blank field means "keep the stored one", so the refresh goes through
/providers/check, which already uses what is saved. That route now answers with
the model names rather than a count, since a refresh needs the list.
One name for one thing: the add form asked for 协议 while the connection list
calls it 接入方式. Its note also still told the user to come back and switch
protocols in place, which was removed for being unsound — two protocols answer
the same model listing but their chat endpoints are different paths, so the
advice now says to add the second one as its own source.
Documentation-impact: none - no docs/*.md describes the run strip's labels or

The index was budgeted at half a percent of the window on the assumption
that its lines were a hint. They are addresses now, and the count of them is
the reach of recall: what falls off the end is what can no longer be asked
for. A percent buys roughly a hundred entries, shared across generations
since the index is cumulative.
It stays the cheapest thing a fold keeps — prose spends hundreds of tokens
to say what a line says, and prose cannot be recalled.
estimateTextTokens returned characters under a name that said tokens, and
estimateMessagesTokens summed it. Every remaining caller compared that against
a budget carved from the context window in real tokens, and three of them were
wrong by the factor between the two units:
- the verbatim tail kept a quarter of what the window had room for (measured:
7931 tokens against a 32768 budget), so recent turns nobody asked to lose
went to the summarizer instead of staying in context;
- a fixed prefix of 30K tokens was read as 120008 and refused compaction
outright, which leaves the context growing to the hard ceiling;
- an interrupted request's reconstructed billing line ran ~4x high.
Both estimators are gone. Everything sizes messages with estimatedPromptTokens
and bare text with textTokens, which is what the trigger, the acceptance test,
and the output clip already used. foldEconomics keeps its old threshold in the
new unit (400 characters is 100 tokens). CompressResult's source_tokens and
projection_tokens now mean tokens to the model reading them.
The two budgets that were wrong now have tests, and both fail if the estimate
is put back in the wrong unit.
A saved source could only be deleted and re-added, and which models read images
was whatever InferVisionModels guessed from their names at add time. That guess
is names-only by design — it cannot know what a relay serving gpt-4o under some
private id can do — and there was no way to correct it afterwards.
Each connection now opens an editor: endpoint, key, which models to keep, which
of them read images, and which is the default. The key field left blank keeps
the stored one, so changing a model list does not mean re-pasting a secret.
The edit merges rather than replaces. UpsertProvider assigns the whole entry, so
building one from this form would silently drop every field the form cannot show
— per-model prices, effort vocabularies, context windows, headers, the preset it
came from. A source with two priced models would have come back with none.
The vision list is the whole answer when it is written: the provider-wide flag
answers for every model a whitelist omits, and a per-model override beats both,
so a toggle that only wrote the list would be a switch that changes nothing.
/providers reports the resolved per-model answer for the same reason — the form
shows what is true now instead of asking the user to remember it.
Documentation-impact: none - no docs/*.md describes the settings pane's source
editor or the provider list fields.
Every fold has left an index of #n addresses since the last change, and
nothing could read one. This is the tool that does: recall names canonical
positions and returns them, with the tool results that answered a call, so
an address is a way back rather than a headstone.
Two things keep it from undoing the fold that made room for it. A recall
draws on a budget worth a tenth of the window, and a request past what is
left is refused whole rather than trimmed — half a span reads as the whole
of what was there. The ledger carries the generation it belongs to, so each
compaction grants a fresh budget with nothing to reset: a stale generation
already reads as unspent.
What is still visible is refused too. The model re-reads that itself, and
the description sends it back to read_file for anything a current copy
answers better. Recall is for what cannot be re-derived: the user's own
words, and the output of work that should not run twice.
The tool schema costs 199 tokens on the provider-visible prefix.
Switching to any Anthropic model failed with
switch model: provider: unknown kind "anthropic" (registered: [openai])
Kinds register themselves from init, so a binary builds only the ones it links,
and this shell linked none of them. openai reached the registry anyway — config
imports it for an endpoint check — which is why the failure looked like it was
about Anthropic specifically rather than about the whole registry being empty.
Nothing upstream could catch it. The picker offers what the config lists, and
the config needs no factory to list it; the old shell and the CLI both carry
these imports, so every other entry point worked. The two tests here fail on the
missing imports, and the second one also holds the curated presets to it: a
preset naming an unlinked kind is a source a user can add and then never select.
Documentation-impact: none - no docs/*.md lists which provider kinds a binary
links.
Two problems the host-only grouping and the silent runner between them made
one report: "切换不来".
The switch was not failing quietly by accident — Settings' run() had no catch,
so anything the kernel refused vanished. It refuses a model switch while a turn
or a background job is running, which is exactly the state a real session is in
and never the state a freshly started one is, so the click did nothing and said
nothing. Every switch on the page goes through that runner, so one line of
reporting covers the model, the effort, the roles and the protocol.
Grouping on the host alone then merged accounts that are not one. A relay
reached with two keys is two accounts — personal beside work, two tenants of
one gateway — and folding them showed one key state and one balance for both.
The account is the host and the credential together, so /providers and /models
carry keyEnv and both lists key on the pair. Where one host really does hold
two accounts, and only there, the config entry's own name joins the label.
A custom relay lands where it should from this: one account, its own models, no
protocol switch offered because it answers on one. The switch appears only for
a host that genuinely has two doors.
Documentation-impact: none - no docs/*.md describes the settings pane's grouping
or the provider list fields.
foldIndexBudget carves a token share out of the context window, but the
render and merge passes costed their lines with estimateTextTokens, which
counts characters. A 128K window granted 640 tokens and bought 640
characters of addresses: around thirteen lines where fifty fit.
The lines are what a folded turn has left, so the shortfall lands exactly
where the digest is already thinnest. Both passes now cost text with
textTokens, the calibrated ratio the rest of compaction plans against.
The fold input path sized itself with estimateTextTokens, which counts
characters, and compared that against a budget carved out of the context
window in tokens. Every stage therefore read a fold as four times its cost:
the omit stage cut a 32-turn English fold to 6 turns, and the guard then
confirmed the result fit — with room for all 32.
summaryInputTokens now goes through estimatedPromptTokens, the same
calibrated estimator the trigger and the acceptance test use, so the
shorten/compress/omit ladder and the budget speak one unit. That folds the
provider-split guardedSummaryInputTokens back into it, and makes the
FoldTokens telemetry a token count rather than a character count.
The model list folded rows by model name across protocols and gave each row a
route selector defaulting to "the active one, else the first". Provider order
put the Anthropic entry first, so every row the session was not already on
defaulted to Anthropic — picking a model moved the session to another endpoint
without being asked. That is what "切换不来" was: the switch worked and did
something the user had not chosen.
Protocol belongs to the connection, not the model. Entries sharing a host are
one account reached through more than one door, so the connection list groups
on the host and carries the switch; the model list shows the models behind the
door currently open, and picking one only picks a model. Changing the door on
the account that is running moves the same model onto the other endpoint —
a real switch, made deliberately, in the place that owns it.
The rows are named for the account now (deepseek, from the host) rather than
for whichever config entry happened to answer. One key and one balance showing
up as deepseek-flash beside deepseek was the whole complaint.
vite's dev proxy was missing /providers, /roles, /account, /hooks, /memory and
/network, so those panels answered with the SPA shell in dev — the same class
of failure the shell's own route list had, and its comment already warned about
it. The list it needs is not derivable from here, so it is spelled out.
Documentation-impact: none - no docs/*.md describes the settings pane layout or
the dev proxy's route list.
The digest is on the hook for what a fold changed and what failed. Everything
else it folded — the reads, the searches, the user turns the retention budget
could not hold — became prose or became nothing, and from inside the window
those two look identical. A model cannot ask for what it has no reason to think
existed.
Each fold now appends a host-written index to its digest: one line per folded
item the digest does not carry, addressed by transcript position.
## Folded work index (#n = transcript position)
- #31 you "the migration must not take the service down…" (summary only)
- #47 read_file internal/parser/lexer.go
- #52 bash go build ./...
- #58 grep {pattern} (1 keys)
The split with the coverage check is exact rather than approximate: an entry is
indexed if and only if coverage does not demand it. Writing that as one shared
predicate found a hole neither half had covered — a successful `go build`
classifies as a mutation but reports no path, so the digest was never asked for
it and the index skipped it as the digest's job. It fell between them.
Ranking decides what survives a bounded index, and the order is not a
preference: a user turn nobody can re-derive comes before a failed search,
which comes before a read whose file is still on disk. The budget is a small
share of the window because index lines are the cheapest thing a fold can keep.
The index carries across folds without being re-summarized. It is stripped out
of any prior digest before the summarizer sees it — asking a model to rewrite
host-authored address lines only spends output budget and risks garbling the
addresses — then merged back, trimming from the oldest and saying how many went.
An entry that has survived more folds is the one whose original is furthest out
of reach, which is the opposite of what a naive tail-trim would keep.
Addresses are canonical transcript positions, the same scheme the projection
already validates through CoveredCount and CoveredPrefixHash, so a rewind that
invalidates the projection invalidates the addresses with it. Positions inside
a previous projection answer -1 and render without an address: that content was
folded once already and has no canonical position of its own.
Nothing reads the addresses yet. The recall tool is the next stage; this one is
what makes it worth having, because a tool that retrieves what the model has no
reason to ask for is a tool nobody calls.
Cache-impact: none - no tool schema, system prompt, or memory text changes. The

canonicalizeOfficialDeepSeekSource drops deepseek-flash and deepseek-pro into
the one "deepseek" entry, but only when every provider-wide field matches it.
A config holding the pair on the Anthropic protocol beside an OpenAI-protocol
"deepseek" fails that test — and correctly, because the fold keeps the
canonical entry and discards the rest, which would delete the Anthropic route.
So the pair stayed two rows while the OpenAI side showed one, and the settings
panel lists sources: one endpoint, one key and one account read as two
accounts. They now fold into each other instead. The survivor keeps the first
entry's name and slot, because provider order answers bare model names and a
new name would break refs that live outside this file — shell history, a
memorised --model. Refs naming the entry that went away resolve to it, and are
asked before the canonical retarget: a "deepseek" entry can exist without
having absorbed anything, and then it does not hold this route.
Per-model price and effort move into prices and model_overrides rather than
flattening, which is the shape ensureDeepSeekOfficialProvider already gives the
canonical entry. On a real config the pro model keeps its three effort levels
and the flash model its four, instead of the first entry's list answering for
both. A curated model list still declines the fold: carrying every model would
re-add the one the user removed.
Documentation-impact: none - no docs/*.md describes how legacy DeepSeek entries
are folded; the config keys involved keep their documented meanings.
Acceptance asked a digest one question: is it smaller than what it replaced. A
digest that summarized nothing answers yes — it is very small — so the one
failure mode worth catching was the one nothing looked for.
A fold is now also measured against the facts it produced. Those come from the
fold region itself, read through evidence.ReceiptFromToolCall, the same pure
classifier the ledger uses; the live ledger is per-task and never spans a fold,
so deriving them is the only way to have them. Two kinds count:
- files the fold changed
- commands the fold saw fail
Reads stay out on purpose. The workspace still holds what a read found, and
demanding reads back would push the summarizer toward listing paths to pass a
check rather than writing what happened.
When the digest forgot a change, one more summarizer call asks for exactly what
went missing — naming the files rather than restating the whole contract, so
the second attempt spends its budget on the gap. The better of the two results
wins.
Repair rather than rejection, and that is the part worth arguing. Refusing a
partial digest leaves the prompt uncompacted; the next attempt folds a larger
region and the pressure only ends at the hard ceiling, where the fold is forced
through whatever it produces. Strictness early buys a worse digest later. The
one case still refused is a digest that carried none of the fold's changes,
which needs no threshold to recognise — and even that stands down when the fold
is the only way out.
No ratio is configured anywhere. The severity line is the mechanism's own: a
forgotten change makes the agent wrong, because it will redo or contradict work
already on disk, while a forgotten failure only makes it slow. Counts land in
the compaction telemetry so the fold's fidelity is reportable rather than
assumed.

The connection rows showed what was configured and nothing about whether it
still holds. A key revoked last week and an endpoint that moved both read as
a normal row, and the only way to find out was to start a turn and watch it
fail.
/providers/check re-runs the add-a-source probe against what is already
saved, so "is this key still good, and is this still the protocol we
recorded" is one button. The row reports the endpoint's own words, because a
401 and "no chat models" send the user to different fixes.
No protocol switch rides along with it, though the row can now tell you the
protocols disagree. A probe only lists models, and it tries both auth shapes
against the same listing URLs, so "both answered" says nothing about where
either chat contract lives: DeepSeek serves OpenAI chat at /chat/completions
and Anthropic at /anthropic/v1/messages. Flipping kind alone would aim one
contract at the other's address and call it a repair. The row says what it
found and leaves the fix to a human who can also change the address.

Compaction is not the class of strategy the last few commits removed. The
context window is a physical constraint, not a judgment about how the model
should work, and every rejection in acceptCheckpointCandidate is already
grounded in a measured token count against the user's trigger or the provider's
ceiling. What did not survive review is the residue of the retired
multi-threshold scheme, and the numbers inside it that were never anyone's to
choose but the host's.
The residue:
- compaction.consecutive was incremented in one place and reset in four, and
read in none. It only ever existed to be cleared.
- soft_compact_ratio / tool_result_snip_ratio / compact_force_ratio are
forced to zero at config load, then threaded from boot through agent
Options and a twelve-parameter task constructor to fields nothing reads.
- SnipStaleToolResults and PruneStaleToolResults were exported no-ops with no
callers, and PruneStats existed to be their return value.
- ContextReport still declared SoftThreshold / SnipThreshold / ForceThreshold,
which nothing populated — and /context both printed them and branched on
them. "LatestPrompt >= ForceThreshold" against a permanent zero is always
true, so every session, including an empty one, reported "next: at the force
threshold". It now names the fold trigger and the hard ceiling, which are
the two thresholds that exist.
The numbers, now under [agent] and all off by default:
user_turn_keep_tokens your own turns kept verbatim through a fold
first_turn_pin_tokens first turn pinned into the cached prefix
checkpoint_ceiling_ratio how small a fold's result must be to be accepted
compact_ratio loses its 0.65–0.85 range. Compacting early to keep prompts small
and compacting late to keep history whole are both real preferences; only a
value that is not a fraction of the window is wrong. The desktop bridge's copy
of the range goes with it.
The user-turn retention budget was min(8192, 5% of window), so it stopped
growing at a 164K window: someone running a million-token model kept the same
8192 tokens of their own words as someone running 128K. It is now the window
share alone, with the fixed count kept only as the fallback when no window is
known. The separate 1500-token per-turn ceiling is gone — the remaining budget
is the only gate, and [[keep]] is still the way to insist on a specific turn.
Because the budget is the user's, /context reports what the last fold did with
it: turns kept, turns dropped and roughly what they cost, and the budget that
decided. noticeDroppedUserTurns already said it once, at the fold; this is what
can still answer afterwards.
Cache-impact: none - no prompt, tool schema, or memory text changes. Fold
behavior is identical for an unconfigured agent: every new setting defaults to
the value it replaced, and the retention budget's window share is unchanged at

An attachment the main model cannot read is already handed down to whatever
sub-agent runs next, and that sub-agent's model was chosen for something
else — usually cost. A cheap worker is text-only, so the provider serializer
drops the image and the turn answers as though nothing was attached. The
composer has been promising a vision-capable reader since it shipped; the
only way to deliver one was to hand-edit subagent_model and give up the
cheap worker.
agent.vision_model names that reader. The routing travels in the turn
context beside the image candidates, because it answers the question they
raise: the parent could not read this, so who can. A sub-agent about to
receive candidates it would drop is moved onto that model; one that already
reads images, or a turn carrying no attachment at all, is left alone — a
review sub-agent spawned in a turn that happened to have a screenshot keeps
the model it was chosen for.
/roles gains the assignment and the band's 看图 slot stops reporting a
borrowed subagent, so what the settings pane shows is now a switch rather
than a readout.
config.roleModelRefs is the one list of model refs a role can name. The
fallback repair and the referenced-provider scan both walk it, and they have
to walk the same one: a role missing from either keeps alive a ref no
provider resolves.

Memory had its limits inverted. The fact index — one line per saved fact,
loaded into the cached prefix and paid for on every session — had no bound at
all, and kept charging for facts already past their expires_at even though
automatic recall refuses to serve one. Meanwhile recall, which rides the cheap
turn tail, was pinned at four facts and 2400 characters by constants no
configuration could reach, and the pinned-guidance ceiling was a flat 1500
characters that told any user with more to pin that they were wrong.
So: expired facts leave the index. A line the model can never act on is prefix
rent, and dropping it is the one bound memory was actually missing.
Everything else becomes the user's, under [memory]:
pinned_budget_chars ceiling on pinned bodies; unset = none
recall_limit facts automatic recall may inject; unset = 4
recall_max_chars that injection's size; unset = 2400
The recall axes keep their old numbers as defaults but lose their ceilings —
configure fifteen and you get fifteen. A hit's snippet is now an equal share of
the char budget rather than a separate 520-rune cap, so it moves with whatever
was configured instead of standing as its own limit. A mid-session reload
carries the budgets forward rather than reverting to the defaults.
What replaces the hard cap is the number itself. `/memory` reports the prefix
cost — index characters and fact count, pinned characters and fact count, the
total, and the budget when one is set — because the axis ships off, and a cost
nobody can see is not a decision anyone can make.
Cache-impact: low - the prefix loses index lines for expired facts, which is
the intended change; nothing else about assembly or ordering moves, and a store
with no expired facts renders byte-identically.

The model pane was one flat list multiplying three independent axes —
which service, which protocol reaches it, which model — while the fourth,
which job a model takes, existed only in the config file. Twenty rows of
radio buttons, and no way to tell which of them reads images.
/models now carries a per-model capability face: the endpoint host, image
input, the effort levels that endpoint accepts, context window, price.
Each resolves back through ResolveModel so per-model prices and
model_overrides apply. A field stays absent when nothing declares it — an
inferred "reads images" badge sends the user to a rejected request with
nothing on screen to explain it, which is worse than a blank row.
The picker groups by endpoint and folds one model's protocol routes into
a single row, so a vendor reached under both OpenAI and Anthropic stops
listing the same model twice with nothing to choose between. Effort
offers only what the endpoint has; the fixed six were shown to every
model, including ones carrying no reasoning knob at all.
/roles gives the planner, subagent and guardian their own models, writing
the AgentConfig fields that already drove them and rebuilding the runtime
the way a model switch does. Image routing has no field of its own yet,
so its slot reports the subagent model it borrows and whether that model
reads images at all — the composer has promised this since it shipped.
A saved vision whitelist no longer raises the provider-wide flag as well.
That flag answers for every model the list omits, so a mixed provider had
its text-only half claiming image input.
Documentation-impact: none - no docs/*.md describes the serve HTTP
surface, and SUBAGENT_PROFILES keeps its meaning: /roles writes
agent.subagent_model without changing its precedence.
Two ladders came down.
The planner gate was scoring task text out of twelve keyword tables — work,
high-risk, cross-surface, ambiguous, atomic — and buying a second model round
from vocabulary. "migrate" was enough. So was a message over 240 runes, or two
file paths in one sentence. What the tables were reaching for is a judgment the
executor is better placed to make: it reads the same words with the repository
in front of it, and lays out steps with todo_write when a task needs them,
where the delivery gates and the contract can both see them. The gate now
answers only "did the user ask for a plan?" — plan mode, a synthetic turn, a
slash command, or a directive the user stated outright ("先规划再执行", "wait
for my approval"). taskpolicy loses the surface-shape signals that fed it for
the same reason: rune counts and path counts described the sentence, not the
work. Risk stays a host signal, and nothing derives one from wording.
The six per-round counters came down with it. A turn was being watched by the
zero-gain ladder (2/4/6), the storm breaker (3 identical failures, 3 all-blocked
rounds), the repeat-failure and repeat-success blocks (2 each), and the todo
stall checkpoints (8/16) — all reading the same receipts, all reaching for the
same "it looks stuck" from a different angle, and each one able to redirect the
model or refuse its call. run_budget.go already says why this was the wrong
axis: rounds are a poor proxy, and the failures worth stopping are reported in
hours and tokens. Those budgets remain, off by default and user-owned. Stopping
a task stays the user's call.
Removing them retires the loop-guard pass in final readiness too — an escape
hatch whose only job was to release a model the guards had cornered.
The outcome scorer survives as an instrument (internal/agent/outcome_shadow.go):
it still decomposes each round for the bench, and still decides nothing.
Net -3250 lines.
Cache-impact: none - the system-prompt prefix is untouched; the per-turn
<execution-policy> block keeps its shape and only ever carried preset-derived
values, which are unchanged for every preset.
Cache-guard: go test ./internal/boot/ (prefix_shape golden unchanged)
Documentation-impact: none - no docs/*.md describes the planner scoring or the
round counters; user-facing copy for plan mode and task budgets is unchanged.
A turn's obligations were being read off its wording. taskintent held ~1200
lines of CN/EN keyword tables, hand-rolled negation windows, and clause
splitting to answer "is this a mutation request?", and final readiness then
demanded a state change from any sentence that scored one. Its own doc.go
called the vocabulary a liability; boundary_test.go existed to stop it growing.
Readiness now reads the ledger: a turn that changed nothing owes nothing, and
one that did owes the verification, review, and sign-off it already owed. The
contract's intent label follows the same rule -- taskcontract.Kind is observed
from receipts after the fact instead of predicted from text -- and the atomic
contract shape is triggered by a mutation receipt rather than by a verb.
taskpolicy keeps the constraints a user stated outright ("don't modify", "only
run go test"): those restrict, and the user meant them. What goes is the risk
guessing, where "migrate" or "credential" bought a full plan and a forced
review from a topic word rather than from what the turn touches. Risk now
arrives only as host-computed signals.
Also removes machinery that decided nothing in production: the EBM and
reasoning-governor experiments (env-gated, off), the fork-bundle capture that
served them, and the shadow delegation-admission verdict. The per-round
contract replay went with them -- it rebuilt the whole contract from every
receipt on every tool round, quadratic in a long turn, for an audit channel
only the bench implements.
Net -3382 lines. Behavior change: a Delivery turn that claims work without
calling a tool is no longer refused. Catching that belongs to the model's own
claim (update_goal / complete_step), which internal/completion already checks
against the ledger, not to a keyword table.
Cache-impact: none - no tool schema, prompt, or memory text changes; the
per-turn <execution-policy> block rides the turn tail as before and its
route/risk values are derived from the same frozen preset.
Cache-guard: go test ./internal/boot/ (prefix_shape golden unchanged)
Documentation-impact: none - taskintent and the two experiments were never
user-facing; no docs/*.md describes the removed gates.
The official source ships as two provider entries, deepseek-flash and
deepseek-pro — a shape from before a single entry could carry several models.
The model picker hid it because it lists models, but the settings panel lists
*sources*, and there one endpoint, one key and one account show up as two
accounts, with every model appearing twice under different refs.
They now fold into the single "deepseek" entry at load, through the
compatibility gate that already existed for exactly this: provider-wide fields
have to match and per-model ones must not conflict, so anyone who edited either
entry keeps what they wrote. Per-model efforts, prices and context windows ride
the canonical entry's overrides rather than being flattened into one.
Refs are deliberately not rewritten. Resolution answers the old names instead,
because refs outlive the config file — shell history, scripts, a --model flag
someone has memorised — and rewriting the four that live in the file would fix
none of those while making Default().DefaultModel disagree with a loaded one.
Model sources, account and versions each get a section, and the 「高级」 tab —
which existed only to say "this still lives in the old app" — filters itself
out now that its list is empty.
Account state is fetched once by App and passed down, and an unknown state
renders as unknown. The first cut drew 「登录」 while the request was in flight
and swapped to 「退出登录」 a few hundred milliseconds later, which is long
enough for a signed-in user to click it and actually sign out. Signing out is
two steps for the same reason, and the button that does it always sits next to
the sentence saying what it does not touch.
The identity entry in the title bar is an outline when signed out: an entry
point, not a pitch. Reasonix works without an account and the chrome should
not imply otherwise.
A settings section that throws now takes down only itself — the other sections
and the conversation behind them are unaffected.
The account and provider endpoints are behind host grants like the workspace
switch already was, so the three of them become one decision — this server is
a window, not a network service — instead of three independent bools spelling
states no host means.
A model or effort switch now carries the serving generation into its
replacement rather than assembling one from cold: sidecars keep running, the
dependency graph is not re-walked, and discovery is reused when the extension
surface has not moved. The switch also stops re-resolving the workspace from
the process working directory, which is what made a rebuild quietly serve
another project's conversations.
Studio's apiPaths was a whitelist that silently answered index.html for
anything unlisted — /skills and /todos had been falling through it for a
while. A test now walks what the frontend actually calls, because the comment
saying "register your route here" plainly did not.
Reasonix runs on the user's own key against their own provider, so there is no
structural reason to require an account and we are not going to invent one.
What an account buys is the handful of surfaces that cannot work without a
server on the other end: posting in the community, following up on a crash
report, publishing a skill later.
`reasonix login` runs the device flow — the browser gets the address bar, we
never show a password field — and the token lands in the existing credential
store, which already carries the file permissions, the edit lock and the
environment override that lets CI inject one.
The serve endpoints are off unless the host grants them, for the same reason
the workspace switch is: signing in writes a token into the credential store
of whichever machine runs the kernel, which is not necessarily the machine in
front of the person clicking.
Adding a provider by hand means knowing which protocol the gateway speaks,
which models it serves, whether it wants a Bearer header, and whether it can
see images — none of which the person who just bought an API key has any way
of knowing. So the endpoint is asked instead: /probe reports what answered,
and nothing is written until the user has looked at it and confirmed. Where
more than one protocol answers, the result says so rather than picking
silently — that is a preference, not a finding.
The probe also retries with the proxy bypassed and reports it, because a
China-only endpoint reached through a foreign exit resets the handshake and
would otherwise look simply dead.
ChatModelList moves out of config.go into its own file; the picker filter has
nothing to do with the config schema and config.go has no room left.
A release that turns out to be bad currently leaves the user hunting for an
old installer. The version panel lists what has been published and installs
any of them — the same code path forward or back, because a rollback that took
its own path would be the less-tested one. The chosen version is pinned before
the download starts: if the machine dies mid-install, the next launch must not
helpfully update past what the user picked.
The update core moves out of the old shell into desktop/internal/update so
both shells share it. Beyond deduplication that finally makes it compile on
every platform — updater_mac.go could not even be type-checked from Windows,
so the macOS half was only ever verified by CI.
Publishing writes a per-tag index alongside the artifacts, so the catalog the
panel reads is produced by the release itself rather than maintained by hand.
Two things the transport learned the hard way, now covered by tests: a 404 is
not transient and must not burn the full retry budget, and a resumed download
has to verify the range it was actually given — a middle box that answers
`bytes 0-` to a range request will otherwise append the whole file to what is
already on disk.
Every path that mints a session file before knowing whether it will be used —
an inbox enqueue, a window that opens and closes, a switch the user backs out
of — leaves a transcript with no user message in it. They accumulate in the
session list forever, and the list is the user's history, not a log.
ReconcileCleanupPending now reclaims them on the same pass that retries
delayed cleanup, after a grace period long enough to cover the gap between
creating the file and the first turn reaching it: a live session holds the
write lease, so it is never a candidate. Reclamation goes through the host's
cleanup path, so a host that trashes deletions trashes these too rather than
unlinking them.
Switching model, effort or extensions used to duplicate that definition at
every call site: serve spliced the fresh system contract over the carried
history by hand, restored session authorizations by hand, and each caller
decided for itself which axes — approval mode, plan mode, a running goal — a
switch was allowed to reset. CaptureRuntimeMigration/ApplyRuntimeMigration
state it once, and BuildRuntime hands back the whole generation (controller,
frozen snapshot, bound closables) so the next rebuild can reuse the assembly
it already paid for instead of rediscovering skills, commands and hooks.
Resume keeps its cold-cache notice; the migration path takes the private
`resume` that records the cache state without announcing an idle gap the user
never sat through — they never left the session.
boot.go was at the file-size ratchet with no room to add a line, so the parts
that are their own concern now live next to it: memory set, phase timing,
plugin specs, skill discovery.
A real profile listed 189 sessions, 154 of them named subagent-sub-*. Those are
a task's internal trace — persisted since the subagent-transcript work so a run
can be continued or forked — and mean nothing outside the session that spawned
them. Switching reasoning effort rebuilds the runtime, the frontend reloads the
list, and a wall of them appeared where the user's own conversations should be.
The rule already existed, spelled inline twice in the downgrade migration with
the reason written out, and was simply missing from the listing. It becomes
store.IsSubagentTranscriptName, next to the sidecar-suffix rule it belongs with,
and the migration now calls it instead of restating it.
It is applied at the surfaces that list the user's own conversations, not inside
IsVisibleSession: recovery GC scans for recovered branches through that helper
and would stop reclaiming a subagent's, leaking them on disk.
Saving a fact is the one tool call that changes what the agent will do in later
sessions, and it happens without being asked. As an ordinary step it scrolled
past between a grep and a read, so the behaviour and the moment it was learned
were never connected — which is exactly the connection someone needs weeks later.
The card says what was taken away and when it will apply: pinned facts ride in
every prompt, relevant ones surface when a turn looks related, and project scope
is narrower than global. Undo sits on the card because it is only cheap right
now, while the conversation that caused it is still on screen. Taking it back
marks the card rather than removing it — the transcript is the record of what
happened, and erasing the row would erase that too.
It reads the call's own arguments, which carry what was saved and how it will be
recalled; the tool's textual receipt carries neither. A failed save stays an
ordinary failed tool call.
Memory is the only thing in the product that changes how the agent behaves
without the user ever configuring it — the agent writes it. Weeks later it
insists on something and there is no way to find out why, because the fact
behind it was saved silently during some conversation.
So the pane answers the question that gets asked, not the one a list answers.
The last recall is folded into the rows: a fact the turn actually used is marked,
and it says what it matched on. Grouping follows activation — always in the
prompt, or only surfaced when the turn looks related — because that is what
decides whether a fact is a standing instruction or background. The write-side
types are the author's classification and do not tell a reader when a fact
applies, so they do not organise anything here.
Forgetting archives rather than deletes, which is the store's existing choice
and the right one for something removed by mistake.
The mock's scripted turn moves to its own file: it is content, not transport,
and mock.ts had grown past the size ceiling holding both.
A wrong proxy shows up as a chat turn that hangs. Nothing in that message says
whether DNS failed, the proxy refused the connection, a corporate MITM cert was
rejected, or the key was simply wrong — four different fixes behind one symptom.
netclient.Diagnose walks proxy → dns → connect → tls and stops at the first
failure, because every later step fails for the same reason and three red rows
hide the cause. The controller appends the auth step, since only it knows which
provider is selected: a host that answers but rejects the credential is a
different problem from one that never answered. Each failure carries the next
thing to try, and an untrusted certificate says so by name rather than reading
as "the network is down".
The pane is three modes, not six proxy variables; the fields for a manual proxy
only exist once that mode is chosen. Saving validates first, because a spec that
cannot even be composed into a URL would otherwise be written and then fail on
every request far from the screen that set it. The stored proxy password is
never handed back to the editor — only whether one exists.
Hooks run arbitrary shell on the user's machine and two of the events can stop
the agent outright, so this is the most dangerous writable surface in the
product. It had no editor here at all: the writing half lived in the desktop
app, and internal/hook could only read.
Save and DryRun move into internal/hook, where the CLI, the desktop and Studio
can share one implementation. Save preserves every other key in settings.json,
which is not a hooks file it happens to live in. DryRun really executes the
command against a representative payload, because a simulated pass proves
nothing about a command that does not exist — and reports the consequence for
that event rather than the exit code, since the same code stops a PreToolUse and
only warns after a PostToolUse. Editing swaps the live runner, so a rule the
user just fixed applies to the next tool call instead of the next launch.
The pane leads with recipes, not events: nobody arrives wanting a PreToolUse
hook with an anchored matcher, they want their formatter to run. The event table
is one click behind that, blocking rules carry a warning stripe, and the scope
choice says out loud that a project rule ships to everyone who clones the repo.
The controller does not keep its own copy of the hook runtime options; the
runner's spawner already binds them, and the second copy would have pushed two
already-oversized files further over their budget.
Adding a server meant leaving for the old desktop app. Bringing it here as a
form would have been the wrong shape: nobody knows whether they want stdio or
http, they have whatever the README printed — an mcpServers block, a command
line, or a URL. internal/mcpsetup takes all three and says which one it got.
Parsing is its own step. What comes back is a card naming the process that will
run on this machine, the endpoint it will talk to, and any credential written
out in full rather than referenced, because a pasted config is a stranger's code
and the user is the one agreeing to it. Where it gets written is a choice, not a
default: a project entry ships to everyone who clones the repository.
Installing connects first and persists only if that worked — a saved entry that
never connects reads as installed while contributing no tools. Authentication is
the exception: its config stays, since finishing OAuth is impossible once the
entry is gone. Removal asks, names the file it will edit, and reports when a
same-named declaration underneath takes over instead of implying it is gone.
The argv grammar, naming rules and secret detection moved out of internal/cli,
which is where the CLI happened to need them first; the frontends take the same
descriptions and cannot import a frontend. ParseArgs lost the 122-line body and
the complexity that came with it rather than carrying that debt to a new file.
The Studio shell matched API paths exactly, so /mcp reached the kernel while
/mcp/reconnect fell through to the assets and answered with index.html. The
frontend then failed parsing HTML as JSON, which is indistinguishable from a
broken endpoint. The dev proxy had the same hole, and had been missing /mcp and
/slash since they were added.
Both now list resource families: a sub-path belongs to the resource it hangs
off, so the next endpoint under one is routed without a second registration.
The extensions page could only report. A failed server named its error and
offered nothing to do about it, a configured server could not be switched off,
and the skill list was built from the slash surface — so a skill the model
discovers on its own, having no slash name, did not appear at all.
Reconnect and the durable activation switch land on the controller, where the
desktop's own copies should eventually collapse into them, and serve exposes
what the controller already knew: /skills now answers every discoverable skill
with its trigger paths and capability face, and /mcp resolves the activation
state so "switched off" stops reading as "not needed yet".
Studio spends it on the row that needs it: a retry button that says re-authorize
when the failure is a 401, a switch per server and per skill, and a trigger note
only on the rows that are missing one. The transcript names the profile a
delegated step ran under, and an MCP tool drops the prefix its own badge repeats.
The session rail ended in two disabled buttons whose explanations were
unreachable — .lnk[disabled] sets pointer-events:none, so the title tooltip
never appeared — and one of them blamed a missing kernel API that has existed
all along in internal/worktree. Both are gone. What they promised is real now,
and each half lives where it belongs.
Skills were already invocable: the kernel resolves /<name> through
resolveSkillInvocation, so the only thing missing was discovery. GET /slash
lists what Submit actually resolves, custom commands ahead of skills in exactly
the order the kernel picks them, and the composer offers it on "/". Built-in
verbs stay out — most are chat-TUI only, and offering one the HTTP path drops
is worse than listing nothing.
Changing the working folder rebuilds the runtime at another root. It is a fresh
boot.Build and never boot.Rebuild: Rebuild migrates the conversation and
continues the outgoing session file, which would drag one project's transcript
into the next. Permission is a host grant (Server.AllowWorkspaceSwitch) rather
than a config key, because a server reachable beyond localhost must not let a
client repoint the agent at any directory it can read. The shell grants it —
its only client is its own window — and reopens the folder it last drove.
Studio also pinned no SessionDir, so every project shared the global session
store and the rail listed another project's history. It now resolves the
per-project directory the CLI has always used.
MCP servers surface in two places, chosen by how much each one changes. The
settings page lists them; the tool card stamps which server answered, because
that is the moment someone can judge whether an external service should have
run at all. The metrics rail stays empty unless one is failing.
The preferences surface was a generic settings skeleton: one bordered box per
option, plus a status strip that existed only because the nav said nothing.
Options are now a single hairline-separated list carrying the same left accent
bar the transcript already uses for state, and every nav row shows its
section's current value — so an approval mode that allows everything reads as a
risk without opening the section.
strings.SplitSeq and a range-over-int clear the two golangci findings this
branch had accumulated in its own files.
Streaming stuttered. It was not the wire: the kernel emits one event per
provider delta and flushes each one, and a probe against a live turn measured
2-3 characters per frame (reasoning p50 3, text p50 2, minimum 1). The cost was
in the client, and it was quadratic.
Two causes, measured on the same fixture back to back (25-card transcript,
40-character chunks). The larger one is first: at 457 characters the p50 was
already 98.6ms, so most of the work had nothing to do with message length —
every token redrew all 24 other cards. Transcript rows are now memoised on
their item, and App's two card callbacks are stable so the memo holds. The
second is the markdown pipeline re-parsing the whole message per chunk; it now
splits on safe blank lines and memoises each settled block. Splitting only the
tail was not enough — re-parsing the settled head whenever a block closed cost
184ms at 7.3K. Result:
457 chars p50 98.6 -> 6.6ms total 1050 -> 110ms
3.7K chars p50 114.1 -> 2.9ms total 10499 -> 275ms
7.3K chars p50 142.4 -> 3.9ms total 26474 -> 854ms
The split changes when parsing happens, never what it produces: 66 prefix
lengths compared, zero differences.
Frames also arrive in bursts (median gap 0ms, 90th 32ms), so arrival order was
being reproduced as visible jitter. Text is now revealed on the frame clock,
draining the backlog proportionally — the lag stays at roughly five frames
whatever the token rate, and the render count drops from 944 frames over 12s to
60/s.
Thinking never streamed at all: the transcript gated the card on answer text,
so 10.2 seconds of reasoning stayed invisible and then landed in one block when
the first answer token arrived. A card now draws with either.
Layout: prose is capped at a reading measure (68ch, about 37 Chinese characters
per line) but code was not, so at 1920px the column was 1333px with prose using
495px of it and a hole to the right. The measure is right; the column was too
wide. --doc binds the flow, the composer and the tabs to one 900px document
column, taking prose from 37% to 59% of the column and leaving code 120 mono
columns. The remaining space reads as a page margin.
Settings drifted from the rest of the UI: .prow was a second copy of the ask
card's .opt with nothing but accidental differences (gap, padding, line-height),
the one dangerous mode only turned red after it was chosen, three theme options
with no descriptions sat in full option rows, and the tablist ignored the arrow
keys the main tabs answer. All four are now consistent, and a status strip
shows what is currently set without visiting each tab.
The session rail was blank and the header showed a filename. The shell mints no
session file at launch by design, so the list starts empty — but nothing ever
refetched it once the first turn created one. /sessions has always carried a
title (generated when ready, first message truncated until then); no surface
displayed it. The list now lives in App, reloads when the session changes or a
run ends, and feeds the header.
MockPort is why none of this showed in development: it answered with a static
session and echoed the prompt into the goal. It now behaves like the kernel. It
is also dev-only now — a shipped build that cannot reach its kernel used to
render a scripted session as if it had happened, and now says so instead.
A read dumped the whole file into the transcript, so one look at a 133-line
file buried the rest of the turn. read_file numbers every line it returns
(" 1→…"), so the count is already in the output and needs no guessing — the
format was measured off a real turn rather than assumed.
Long reads collapse to "读了 133 行" and open on click; short ones stay inline,
because folding nine lines only adds a click. Verified against a real turn:
the details box is 21px closed and 2570px open.
A tool card rendered stdout and nothing else, so a command that failed looked
exactly like one that worked. The status was on the wire the whole time —
tool.execution carries state, exitCode, failurePhase and outputTail — but the
field was never declared, so the client could not see what it was already
being sent.
The card now carries a small pill in the error colour, shaped like the tag
beside it. It prefers the exit code over the state word: "failed" only repeats
what the colour says, while "exit 2" is the part worth reading.
The badge is live-only. A reload rebuilds the transcript from /history, which
is the provider conversation and has no execution on it — the same reason
durations disappear. The failure text itself survives, because the kernel puts
it in the tool output too.
Opening a session that contained math went white. KaTeX throws on an undefined
control sequence by default — verified directly: \badcmd{x} raises, the same
input with throwOnError:false renders the source in red — and a throw during
render unmounts the tree, so the window goes blank over a single token the
model happened to write.
Two changes, because the second one is the point. KaTeX no longer throws. And
each message renders inside an error boundary that falls back to its source
text, so anything else the renderers choke on costs that one message instead
of the whole conversation. Model output is arbitrary text; the transcript
should not be one unlucky token away from an empty screen.
Thirty sessions were clicked through to find it, and none of them contained a
formula, which is why the earlier passes came back clean.
The model answered an integral question in \[…\] and \(…\), and nothing
rendered: remark-math reads only dollars, so no math node was ever built, and
the lazy-load detector — which also looks for dollars — never fetched KaTeX
either. Both layers missed it for the same reason.
The delimiters are rewritten to dollar form before parsing, which keeps one
math parser rather than teaching two of them a second syntax. Code is split
out first: a \[ inside a fence is text, and an equation is not.
Walking a real turn through the browser found three things the earlier passes
could not, because they only checked that the page rendered.
/trajectory reached neither allowlist — not the vite proxy, not the shell's
apiPaths — so it fell through to the SPA and the HTML parsed as a failure the
caller swallowed. The persistence committed in 446f1217f therefore never
worked in Studio at all: the pane was empty on every reopen. With the route in
place a reload reads 19 frames back and draws 17 rows.
Both decision cards read their sealed state off the item, and the reducer
never recorded one, so an answered question stayed answerable and an approved
write kept offering its three buttons. The decision is now stored when it is
made: the ask goes read-only with a line naming what was chosen, the approval
states what allowing once actually means, and the chosen option stays on
screen because reviewing an old turn is the point.
turn_done carries the kernel's reason, and reducing it to "失败" threw that
away — the run above wrote its file and answered the follow-up, then was
flagged for not verifying afterwards. That reads nothing like failure, so the
reason is shown instead of the word.
Cards showed the raw tool id and one generic "正在执行…" for everything. The
spec names a call by what it is — Read, Search, Update, Task — and derives the
running line from its category, so "正在读取…" and "正在联网…" come out without
per-tool copy. The id has not gone anywhere; it is the tag beside the name.
KaTeX and its fonts were half the bundle — 906kB down to 267kB by splitting
them out — and most coding sessions never produce a formula. The plugin and
its stylesheet now load on the first message that contains math, cached at
module scope so it happens once per run.
remark-math stays eager: it only parses $…$ into nodes, and until the chunk
lands those render as their source text, which still reads. A failed fetch
degrades the same way rather than blanking the message.
The detector uses no lookbehind. Older WebKit treats it as a syntax error and
takes the whole page down with it, which is how the macOS 12 blank screen
happened.
Every session opened grew a phantom "archived" entry in the rail. The wire log
I added ends in .jsonl, and IsSessionTranscriptName classifies any .jsonl that
is not explicitly excluded as a primary transcript — the exact trap
SessionEventLogDamaged's comment already warns about. The listing was faithful;
the file had never been declared.
Declaring it once fixes more than the listing. SessionSidecarFiles is what
delete, rename, migration and recovery GC all walk, so an unregistered
companion would also have outlived the session it belongs to. serve now asks
store for the path instead of building the name itself, leaving one owner for
the convention.
KaTeX renders $…$ and $$…$$, :shortcodes: become emoji, and mark/sub/sup/kbd
are allowed through. Raw HTML is parsed and then cut back to an allowlist:
model output is untrusted markup, and nothing that can navigate, load or
script survives the filter. Subscript and superscript ride that same channel
rather than a shorthand plugin — Pandoc's ~2~ collides with GFM's
~~strikethrough~~, and one mechanism beats two that fight over a tilde.
Plugin order is load-bearing: raw parses HTML into nodes, sanitize prunes
them, katex renders after so its own generated markup is not pruned in turn.
Code blocks now render as .term, the box every tool result already uses, and
inline code falls to the .out .txt code rule the spec always had; the parallel
set I had invented for them is gone.
A long session title ran underneath the delete control, which is positioned
over the row. The title now stops short of it, reserved even while the button
is hidden so revealing it on hover does not reflow the text.
Deleting the active session raised 409 from the kernel, and the rail relayed
the transport string — "/delete-session: 409 cannot delete active session" —
which is plumbing, and offered on a button that could never succeed. Stepping
off the session first is what the action means: a new session becomes current,
the transcript clears with it, and the old file is then free to remove. The
confirm reads "关闭并删除" on that row so the consequence is stated before it
happens rather than explained after it fails.
The pane was built from the live stream alone, so re-entering a session showed
an empty table. Nothing was on disk to reload: trajectory.Recorder is wired
into the CLI and e2ebench, never into serve, and the .events.jsonl beside each
session is a conversation projection with no timings, usage or audit records.
Serve now mirrors the broadcast frames it already hands the SSE clients into
<session>.wire.jsonl, and GET /trajectory reads them back. Frames are what the
pane consumes, so replaying them reproduces it row for row with no second
schema in between; internal/trajectory keeps recording its richer audit stream
for offline analysis, which answers a different question.
Only kinds the pane draws are kept. Streamed text and reasoning arrive one
frame per chunk and would be nearly the whole file while contributing no rows,
and dropping them is what makes it affordable to close the handle after every
write — a retained one blocks the session directory from being removed on
Windows, which is how TestConcurrentResumeAndForkKeepAlignment caught it.
Deleting the active session is refused by the kernel with 409, but the rail
collapsed the row and reloaded regardless, so a rejected delete looked like it
had worked. The failure now restores the row and surfaces the reason.
The ask tool raises both a tool_dispatch and an ask_request, and the transcript
drew a card for each: two copies of the same question, both answerable. Worse,
the copy built from the tool call carried tool.id where /answer expects the ask
id, so submitting it addressed a question the kernel has no record of and did
nothing. AskFromTool is gone; ask_request is the only interactive surface.
The trajectory footer claimed the rows came from what internal/trajectory
persists. Only the CLI builds a Recorder — serve builds none — so nothing is on
disk and re-entering a session shows an empty table. The note now says what the
pane actually is.
Three provider blocks on one endpoint — a two-model block plus a single-model
block per model, each pinning its own price — made GET /models return the same
two models four times. The refs differ, so nothing was wrong with the data; the
picker just asked the user to choose between rows that resolve to the identical
endpoint, key and model. Entries are now collapsed by (endpoint, model).
The survivor is the active entry, so the current selection stays selectable,
then the default, then the single-model block, whose price table is the exact
one rather than a provider-wide fallback. Distinct endpoints are left alone:
one model name at two vendors is two real choices.
Settings only lived under the project picker, whose affordance is "switch
project" — nobody clicks a project name looking for preferences, and ⌘, only
helps people who already know it exists. That matters most exactly when it is
hardest: recovering from a bad API key requires finding this screen. It gets
a button in the chrome's icon cluster, reusing the theme toggle's class so it
sits in that weight class rather than competing with the preset control. The
menu entry and the shortcut stay; two doors to one room is not clutter.
Deleting a session snapped the row out instead of collapsing it: the CSS
transitions height, but the row is content-sized and height:auto has nothing
to animate from. Pin the measured height and force a paint before the
collapsing class lands. Leaving the row now cancels a pending confirm, which
had no way out short of deleting.
Wails v2's windows options expose DisableWindowIcon but no Icon: the title
bar and taskbar read the icon out of the executable's resource section. The
shell builds with plain `go build`, which emits none, so it shipped with the
stock Go binary icon. go-winres compiles build/appicon.png into a .syso the
linker picks up automatically. Committed rather than generated at build time
so `go build ./next` alone produces a correctly branded binary.
frontend-next had the design's stylesheet ported in full but only a fraction
of the markup using it. This fills in what the spec calls for: the project
picker, preset segmented control and theme cycle in the chrome; activity and
trajectory as sibling panes with a shared composer; model, effort, plan and
approval as real menus rather than labels; and the cache, subagent, job, plan
and pending-change blocks in the metrics rail. The traffic lights are gone —
they imitate a control Windows puts on the other side of the title bar — and
the wordmark takes that slot, masked so it follows the theme instead of
carrying one hard-coded blue. Tool glyphs move to lucide-react, matching the
version desktop/frontend already pins.
Six defects surfaced while wiring it to the real kernel:
/models returns {current,label,models}; the client parsed it as an array, so
the model menu would have thrown the first time it opened. Mid-turn input
went to /submit, which 409s once a turn holds the session — it belongs on
/inbox/items with intent=steer. The Wails allowlist was missing
/provider-setup, so it fell through to the SPA and the 200 HTML parsed as a
failure the caller swallowed: a user with no key never saw onboarding. The
mock probe treated vite's SPA fallback as a live kernel and booted SsePort
against HTML. A turn blocked on approval still read as running, so the glow
kept animating and the action slot offered stop instead of send.
The last one was the user's own message never appearing: both event.Message
emitters carry assistant text, so nothing on the wire echoes what was typed —
only /history has it, after a reload. The client owns that turn now, and the
dead itemId=="user" branch is gone. Assistant text renders as markdown
(react-markdown + remark-gfm, matching desktop/frontend) with the caret the
spec always had and nothing used.
The shell forwards broadcaster frames over the Wails bus. Its asset server
buffers a response until the handler returns, and the SSE handler never
returns, so /events delivered nothing inside the window — silently, with no
error to see. The payload is byte-identical to what the browser reads; only
the transport differs, and a replay path covers the reload the bus has no
handshake for. It also no longer mints a session file at launch, which left
an empty transcript behind every time the window opened.
GET /sessions generated a missing title inline, one model round-trip per
session, serialized. With 29 sessions and 17 cold entries the list took 11.7s
to render; warm it was 44ms. A title is decoration on a navigation list, so
the request no longer waits for one: a cache hit is used, a miss returns the
preview and queues generation on a bounded background pool that writes into
the same cache for the next read. Cold-start now measures 0.052s.
TestSessionTitleDoesNotBlockOnGeneration pins the contract with a provider
that never returns, so the wait can't come back. The recording fake grew a
mutex because generation moved off the request goroutine.
/status gains workspaceRoot. cwd reports SessionDir — where transcripts are
stored, not the tree the agent edits — so a client had no way to name the
workspace it is pointed at.
preset, model, effort and status move to settings.go. serve.go was 941 lines
over its repolint budget after the previous commit added the three endpoints
without resyncing the ratchet; extracting them puts it back under at 1642.
The existing desktop frontend talks to the kernel through Wails bindings, so
its App surface has grown to ~950 methods — most of them shell concerns (tabs,
themes, tray, updater) rather than kernel capability. A UI built on that is
welded to the shell.
frontend-next talks to control.Controller the way the chat TUI and the HTTP
server already do: as another frontend, over internal/serve. It depends on one
interface (AgentPort) with two implementations — SsePort for serve, MockPort
replaying a fixture — so the same build runs in a browser with no Go process
and inside Wails with no port open. desktop/next mounts serve.Handler() as
AssetServer middleware: in-process HTTP, no port, no CORS, no second transport
to keep in sync.
port/wire.ts mirrors internal/eventwire field for field. That is deliberate:
every place this file was written from what seemed reasonable instead of what
the kernel emits turned out wrong — /history returns the provider conversation
rather than the event stream, tool calls are camelCase, todo payloads live in
args and not output, user turns arrive wrapped in control-plane blocks that are
instructions to the model rather than anything the user said, and /submit takes
"input", not "text". A mismatched key there is a request that 400s with nothing
on screen, so the client now surfaces failed writes instead of dropping them.
The existing frontend, main.go and wails.json are untouched; the new shell is a
separate main package and builds with -tags desktop,production.
The controller already had SetAgentPreset, and serve already had switchModel
and switchEffort — but the only way to reach the latter two over HTTP was by
sending "/model <ref>" through /submit and having the handler intercept the
string. A browser client had to compose slash commands to change runtime state.
Add POST /preset, /model and /effort, each forwarding to what already exists.
/status gains preset, effort, modelRef and sessionPath: without them a client
can set these but never read them back, so the controller stops being the
single source of truth for its own settings. sessionPath in particular is what
lets a client tell which session it is in — a fresh session has not been
written to disk yet, so it is absent from the /sessions directory listing.

prompt="Three independent modules — billing/, shipping/, and notify/ — each have exactly one defect, described in their own README.md. They share no files. Dispatch all three fixes in parallel with a single `fleet` call, giving each task the write_paths for its own module directory, then confirm that `python3 check.py` prints OK."

prompt="Write a Go command-line tool called wordfreq in this directory. It reads the text file named by its argument, counts words split on whitespace, case-insensitively. By default it prints the top 10 by descending count, one `word count` per line separated by a single space. Support -n N to change how many, and -json to emit a JSON array whose elements look like {\"word\":\"the\",\"count\":5}. Put package main at the repository root and use the module name example.com/wordfreq. `go build ./...` and `go test ./...` must both pass, and write your own tests covering the counting logic."
prompt="Add a Delete(key string) error method to the store package, with semantics consistent with the methods already there. Deleting a key that is absent must behave the same way Get does in that situation. Add tests in the style the package already uses."
prompt="TestCreateOrderAtLimit fails: an order whose quantity is exactly the ceiling is rejected, but the limits are inclusive. Find it and fix it. Do not touch code unrelated to the defect."
