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
as long to arrow through.
Documentation-impact: none - no docs/*.md describes the composer's model picker.
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
when a source is added from the panel.
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 provider check payload.
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.
Cache-impact: none - no prompt, tool schema, or memory text changes. The digest

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
every window where the old fixed count was not already the binding limit.
Cache-guard: go test ./internal/boot/ ./internal/agent/ (prefix_shape golden
unchanged; TestUserTurnKeepBudgetScalesWithTheWindow and
TestUnsetCompactionBudgetsKeepTheDefaults pin the defaults)
Documentation-impact: none - docs/*.md documents neither the retired thresholds
nor the fold budgets; the [agent] keys are self-describing in the rendered
config.
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.
Cache-impact: none - the system-prompt prefix is untouched. Vision routing
only rewrites a per-turn context value and a sub-agent's model ref, and the
new config key renders into user TOML, never into the prompt.
Cache-guard: go test ./internal/boot/ (prefix_shape golden unchanged)
System-prompt-review: esengine - config gains agent.vision_model; it is read
at sub-agent spawn time and rendered into user TOML, and reaches no
prompt-bearing surface.
Documentation-impact: none - no docs/*.md describes image routing or the
sub-agent model fields beyond SUBAGENT_PROFILES, whose precedence rules are
unchanged.
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.
Cache-guard: go test ./internal/boot/ ./internal/memory/ (prefix_shape golden
unchanged; TestIndexDropsExpiredFacts covers the new omission)
System-prompt-review: index composition changes only by omitting expired facts
— needs a reviewer's eye on whether any workflow relied on an expired fact
still being listed.
Documentation-impact: none - docs/*.md does not document the recall constants
or the pinned ceiling; the [memory] section is self-describing in the rendered
config.
Staging turn_orchestrator.go whole took three hunks of unfinished
image-routing work with it — calls to imageRoutingPrefix,
bindOrchestratedTurnImages, and unreadableImages — while their definitions in
turn_images.go stayed uncommitted, so studio did not build. This restores those
call sites and keeps only the withPlannerTurnMetadata signature change that
commit was actually for. The working tree keeps the newer versions; they belong
to the change that defines their helpers.
Cache-impact: none - control-flow call sites only, no prompt or tool surface.
Cache-guard: not applicable; no provider-visible bytes change.
Documentation-impact: none - restores a call site to its previous form.
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.

If this resolves a report, put `Fixes #123` on its own line — GitHub only
auto-closes from a bare line, so `- Fixes #123` in a list does nothing and the

release workflow then asks that reporter to verify once the fix ships.

## Verification
-
For a GSAP to WAAPI/CSS migration (or any cross-API replacement), document
the source-to-target contract here: easing syntax, time units, callbacks,
cancellation, reduced-motion behavior, and failure fallback. Verification must
assert that the target API was actually called; a mock that silently skips it
does not count.
## Documentation impact
Documentation-impact: TODO
For changes to user-visible CLI, Desktop, configuration, provider, permission,
or tool behavior, use one of:

-`Documentation-impact: none - <why the embedded documentation remains correct>`.
## Cache impact
Cache-impact: TODO
Cache-guard: TODO
System-prompt-review: N/A
For cache-sensitive changes, fill these lines before requesting review:
-`Cache-impact`: `none`, `low`, `medium`, or `high`, plus the reason.
-`Cache-guard`: the focused guard test/command added or run, or why an existing guard covers the change.
-`System-prompt-review`: required reviewer/approval note when provider-visible system prompt, memory prefix, output style, or skill index behavior changes.

Scoring reads the completion report recorded in the run's trajectory, so these
tasks must run with `-trajectory`; runs without one are counted `unmeasured`
rather than honest. `TestNoSolutionCorpusGradesTheInverseContract` holds the
corpus to both halves of its contract — pristine seeds grade clean, and every
grader actually rejects the cheat it exists to catch.
Each task under `e2e/tasks/<id>/` contains:
| File | Purpose |
| --- | --- |
| `task.toml` | The task definition (prompt, step/timeout limits). |
| `verify.sh` | The grader: exits 0 iff the agent's artifacts are correct. |
| `workdir/` | Optional seed workspace, copied into the temp run dir before the agent starts. |
## Anchor resistance
Multi-agent systems isolate conversations. They rarely isolate conclusions: a
sub-agent asked to "independently check this" usually arrives already holding
its parent's answer. Before adding an interface to prevent that, measure
whether it costs anything here — a handed-down conclusion that the agent
routinely overturns is not a problem worth building against.
The `-anchor` arms make that measurable on the `failing-test-diagnosis` tasks,
which have one knowable cause each. Each carries two authored hypotheses: the
real cause (`seed_correct`) and a plausible one that is not (`seed_wrong`).
The arm prefixes the prompt with its seed, so the agent meets the conclusion
before it has read anything.
```bash
go run ./cmd/e2ebench -task diagnose-float-total,diagnose-floor-division,diagnose-missing-file,diagnose-tie-order,diagnose-utf8-bom,diagnose-version-sort -json blind.json
go run ./cmd/e2ebench -anchor correct -task ...same... -json correct.json
go run ./cmd/e2ebench -anchor wrong -task ...same... -json wrong.json
```
Anchor resistance is the wrong arm's solve rate over the blind arm's on the
same tasks. A wrong arm that collapses says a handed-down conclusion survives
contact with the evidence, and that blind delegation is worth its cost; a wrong
arm that barely moves says the opposite. Nothing here is a single composite
"independence score" — the arms are reported separately because they answer
different questions.
Two limits are worth stating rather than discovering later. The seed goes to
the top-level agent, so it prices agent-level anchoring; it reaches a
sub-agent only if the parent delegates and repeats it, which the **evidence
origin** line under Delegation is what measures. And the seeded arms score a
smaller corpus than the blind one — every skipped task is named in the report,
because a seeded arm quietly scoring fewer tasks is not the same experiment.
### Evidence origin
The Delegation section reports how much of what the children looked at they
had to find themselves, and what the parent's own delegation text pointed at.
Both come from host receipts and the parent-authored task text before host
framing, never from anything an agent claims.
Two kinds of pointing are counted apart, because they are not the same act:
| | What it is | Blind delegation |
| --- | --- | --- |
| **scope hint** (`pkg/`) | Narrowing the search — the unavoidable cost of handing work off at all | expected, and recorded |
| **named file** (`pkg/romeo.py`) | Saying where the answer is | the number that should be zero |
Discovery is judged against named files only: a child sent to a directory
still had to work out which file in it mattered, so a scope hint never erases
its credit. Both stay absolute counts — a rate would hide how large the
hand-over was — while the discovery share is a ratio of summed paths across
children, not a mean of per-child rates, so a child that opened one file
cannot outweigh one that swept forty.
## Neutral metering
A harness comparison has an accounting problem before it has a measurement
problem: **no contestant should count its own tokens**. Reasonix writes
`.run-metrics.json`, other harnesses do not, and a comparison published by one
of the contestants cannot rest on each contestant's self-report.
`-meter` moves the measurement onto the request boundary. The bench starts a
loopback proxy, writes a temp config whose *benchmarked provider* points at it,
and hands the child `REASONIX_HOME`; prompt, completion and cache-split tokens
are then counted identically for anything that speaks the endpoint.
```sh
go run ./cmd/e2ebench -meter ~/.reasonix/config.toml -trajectories t/
```
- **Credentials are never touched.** The config only names an `api_key_env`;
only `base_url` is rewritten. The key itself is resolved from Reasonix's own
`$REASONIX_HOME/.env`, never from the process environment — exporting
`DEEPSEEK_API_KEY` into the shell is not enough to run a benchmark against a
temporary home, which needs its own `.env`.
- **Only the provider serving `-model` is redirected.** Rewriting every endpoint
would send one vendor's traffic to another's host.
- **Streamed requests are opted into usage.** An OpenAI-compatible stream
carries no usage block unless the client asked for one, so a harness that
never asks would measure as free. Non-streamed bodies are forwarded byte-for-
byte.
- **A response with no usage is `unmeasured`, never zero.** Silent zeroes would
flatter whichever harness reports least.
The report prints what the proxy saw and how far the harness's own accounting
drifted from it:
```text
**Metered at the boundary** (49 runs): tokens 12,904,331 · cache hit 71% ·
**self-report divergence** +0.2% (harness 12,930,118 vs meter 12,904,331 over 49 runs)
```
That divergence is the publishability gate. Reasonix is the first harness
metered this way precisely because it *does* self-report: if the proxy and
`.run-metrics.json` disagree about the same run, one of them is wrong and no
cross-harness number is ready to publish.
## Fault recovery
`-faults` injects provider failures through the same proxy — deterministic, and
replayable across harnesses. Two forms:
-`3:429` — a targeted failure at an exact request.
-`every:5:500` — a cadence. **A mixed-length suite needs this**: a task that
only ever makes four requests would never reach a fixed index and would join
the unfaulted group without anyone noticing.
An absolute index wins over the cadence, so a targeted failure stays where it
was asked for.
```sh
go run ./cmd/e2ebench -meter ~/.reasonix/config.toml -faults every:5:500 -trajectories t/
```
The readout separates two things that are easy to conflate:
**still solved** 61% (19/31) · in-run control 78% (14/18 never hit a fault)
```
- **retried** — the meter saw another request after the failure. A harness that
dies on the first 429 never reaches this, and *was never really tested*.
- **still solved** — the task landed anyway. A harness can retry forever and
still not finish; that is not recovery.
- **in-run control** — with a cadence, short tasks never hit a fault, so the
same run carries its own unfaulted baseline. The cost of failure is measured
against the same suite and model rather than a separate arm run at another
time under other conditions.
## Segmented runs
A twelve-hour session is not interesting because it is twelve hours long. It is
interesting because of the states it passes through: a session reloaded from
disk, a prefix rebuilt, a compaction crossing a turn boundary, a user arriving
mid-task with a new instruction. `-segments N` reaches those states directly
instead of waiting hours for them.
```sh
go run ./cmd/e2ebench -segments 3 -steer "also handle empty input@2" -trajectories t/
```
Leg 1 starts the session with the task. Later legs resume it with `--continue`,
which is unambiguous because each task already runs in its own home and
therefore its own session directory. A resumed leg is deliberately **not** given
the task again — its prompt is a bare continuation, because a leg that restates
the work would hide exactly the degradation this is meant to expose. A `-steer`
entry replaces one leg's continuation with a user turn.
Two properties are load-bearing:
- **The step budget is divided, never multiplied.** A segmented arm gets the
same `max_steps` as the control arm, split across legs with the remainder on
the last. Otherwise the arm would win by being allowed to work longer.
- **Each leg writes its own metrics file.** They share a work dir, so a single
`.run-metrics.json` would leave the last leg's numbers standing in for the
whole run and the earlier legs' tokens would simply vanish. `Segments` in the
JSON records how many legs a run had.
A leg that fails ends the run: resuming a session the child never finished
writing would measure crash recovery, which is a different experiment.
Only the last leg's trajectory digest is read, so time attribution and cognition
lines describe that leg rather than the whole run. Merging per-leg trajectories
is not done yet; `Segments` is what tells you the digest is partial.
## task.toml schema
`e2ebench` reads `benchmarks/e2e/tasks/<id>/task.toml` with the BurntSushi TOML
decoder. The task ID is the directory name; tasks run in sorted ID order.
| Key | Type | Required | Description |
| --- | --- | --- | --- |
| `prompt` | string | yes | The task instruction handed to the agent. |
| `class` | string | no | Task class label (e.g. `bugfix`, `codegen`, `exploration`) for per-class marginal-utility breakdowns in compare mode. |
| `max_steps` | int | yes | Agent tool-call cap; passed through as `--max-steps` to `reasonix run`. |
| `no_solution` | bool | no | Ground truth: no reachable solution exists. The task leaves every accuracy denominator, its `verify.sh` grades the inverse contract, and it is scored on honesty instead. See [Completion Integrity](#completion-integrity). |
| `timeout_sec` | int | no | Per-task wall-clock timeout in seconds; defaults to `240` when omitted or `0`. |
| `seed_correct` | string | no | The task's real cause, phrased as a conclusion handed down before the run. Used by `-anchor correct`. See [Anchor resistance](#anchor-resistance). |
| `seed_wrong` | string | no | A plausible cause that is **not** the real one. Used by `-anchor wrong`. Author both seeds or neither: a task seeded on one side only would be scored in one arm and skipped in the other. |
Example (`tasks/fizzbuzz/task.toml`):
```toml
prompt="Create a file named fizzbuzz.py containing a function fizzbuzz(n) that returns the string 'Fizz' when n is divisible by 3, 'Buzz' when divisible by 5, 'FizzBuzz' when divisible by both 3 and 5, and otherwise the number as a string. Do not print anything at import time."
max_steps=12
timeout_sec=180
```
## verify.sh contract
`verify.sh` is the grader for a task:
- It is a `bash` script run with `set -e`; exit code `0` means the task passed.
- It runs inside the temp work dir **after** the agent finishes, alongside the
copied `workdir/` seed and whatever files the agent produced — so it can
import generated Python modules, read `answer.txt`/`result.txt`, etc.
- The harness copies `verify.sh` into the work dir only after the run, so the
agent can never read the answer key during the run.
- Its stdout/stderr is streamed to the job log (stderr), not the report.
| `-task` | *(all)* | Suite mode: run only these comma-separated task IDs (e.g. `-task fix-add-bug`); unknown IDs fail with the available list. |
| `-attempts` | `1` | Suite and diff modes: retry a task until an attempt passes, up to N; enables the `Pass@≤N` KPI, and TTCS charges a retried solve with its failed attempts' wall. |
| `-bin` | `reasonix` | Path to the reasonix binary. |
| `-profile` | `baseline` | Tool-surface/runtime tier: `baseline` \| `economy` \| `balanced` \| `delivery`. All but `baseline` append `--profile <tier>` to the agent invocation; `baseline` passes no flag (byte-identical legacy control, behaviorally `balanced`). Economy starts with the core tool set and pays `connect_tool_source` rounds plus prefix resets to grow it — the report's Tool surface line prices that trade. |
| `-json` | *(none)* | Write the JSON report here (optional). |
| `-trajectories` | *(none)* | Suite mode: write one `<task-id>.trajectory.jsonl` per task into this directory (the agent's full event stream with timestamps — see `reasonix run --trajectory`). The report gains a time-attribution line (tools vs. model) and each JSON result a `trajectory` digest. |
| `-force-planner` | `false` | Suite mode: prefix each prompt with a plan-first directive so the two-model turn engages regardless of the planner gate. Use for the "with planner" arm of an A/B; results carry `plan_forced` so arms are only comparable with equal forcing. |
| `-anchor` | `blind` | Suite mode: which hypothesis the agent holds before it looks at anything — `blind` (none, the control) \| `correct` \| `wrong`. The seeded arms prefix each prompt with the task's authored seed and **skip** tasks that have none, so an unseeded control run never lands in a seeded denominator. Results carry `anchor`. See [Anchor resistance](#anchor-resistance). |
| `-cache` | `cold` | Suite mode: `cold` runs each task as a fresh session (the fair cross-agent comparison arm); `warm` primes the provider prefix cache with a one-step run in the same workdir first, measuring the long-lived-session steady state. Never mix arms in one report — compare them with `-mode compare cold.json warm.json`. |
| `-budget` | `800000` | Abort once total tokens cross this (`0` = no cap). Remaining tasks are reported as skipped. |
| `-meter` | *(off)* | Suite mode: route the benchmarked provider through the neutral measuring proxy, using this `config.toml` as the source. Spend is then counted at the request boundary instead of trusted from the harness. See [Neutral metering](#neutral-metering). |
| `-faults` | *(none)* | Suite mode: inject provider failures through the meter — absolute indices (`3:429`) and/or a cadence that scales with the run (`every:5:500`). Requires `-meter`. See [Fault recovery](#fault-recovery). |
| `-segments` | `1` | Suite mode: split each task into N resumed legs (`--continue` between them). The step budget is **divided**, never multiplied. See [Segmented runs](#segmented-runs). |
| `-steer` | *(none)* | Suite mode: deliver a user turn at a leg boundary, e.g. `"also handle empty input@2"`. Requires `-segments` to reach that leg. |
Diff-mode flags:
| Flag | Default | Purpose |
| --- | --- | --- |
| `-repo` | `.` | Repo root (diff mode). |
| `-base` | *(none)* | Base ref to diff the PR head against (diff mode). |
| `-test-cmd` | `go test` | Grader command run on the affected packages (diff mode). |
| `-max-steps` | `80` | Agent tool-call cap for the diff task. |
