Consolidates the four contributor changesets, and rewords the em-dashes this release
added in comments and docs. The five in test/settings-save-failure-ui.test.ts stay:
they assert existing toast text.

The startup hint is no longer typed, a Discord reply is one of the input paths that
set fromUser, edit-history is a state file, POST /api/filesystem/mkdir is in the API
reference, and the store's header says which routes really refuse it.

Owner decision. Typing the note into a brand-new non-Claude tab spent a model
turn per tab and, for a spawned worker or a scheduled run, landed with the first
real prompt. Claude keeps its hint through the system prompt, and every other CLI
is told nothing. The setting goes with the path it gated: sessionIdle, the fresh
set, isHintableSession and the session:idle wiring. sendInput loses `fromUser`,
which was only ever false for the hint, and the deps test pins that a reply is a
person's own input.

`cwd` beside the fixed `workingDir` reads ambiguously on a public API surface, and
`paneCwd` says where the value comes from, like `paneExit`. Also pin the field on
the payload the browser really receives (getSessionStateWithRespawn), and give the
pane-directory text its own architecture-invariants paragraph.

Round-four review smaller items: api-reference now states the opposite-of-apiKey behaviour for an omitted defaultContextLength, and the wiki sentence follows the code, modelContextLengths[id] ?? defaultContextLength: any stored figure beats the default.
- share one context-length resolution (discovered figure, endpoint default fallback) across the routes and boot recovery, with a recovery test
- record listed per-slot context figures with a slot count of 1 and force the slot-count fallback once per rediscovery
- open up the codex model launch token for qwen3-style ids (model-plain-colon), pinned by a spawn-golden case
- pass the full discovered window to opencode as limit.context
- translate the picker search strings and document the discovery precedence
A direct clone whose git-slot wait timed out came back with no spawnError, so
the cleanup emptied a folder git never touched. GitRun now says whether git
started and the cleanup requires it. Cloning into a folder at or inside a
Docker case workspace is refused, as git status, fetch and worktrees do, since
git would run the new repository's hooks and filters on the host.
A direct clone into an empty folder emptied the folder after any failure, which
deleted a concurrent attempt's finished clone when git had written nothing.
Clones into one folder are now mutually exclusive in-process, the cleanup is
skipped when git refused the folder, never ran, or the mount is unresponsive,
and a name linked while the clone ran is a 409 that keeps the folder.
Documents path for POST /api/cases/clone.
- lone digit rule in CLAUDE.md, invariants, user docs, wiki, API reference and code comments
- say which installs have the codeman command
- reload() comment back above reload(), merge the sendInput comments, typedHint in the hint comment
- drop the stray dot after --urgent in the startup hint
- config-backups wiki: name the discord.json token, not the URL
- comma in the CLAUDE.md auto-named list
- codeman notify exits 1 when the route answers 200 with data.ok false
- notify request times out at 30 s instead of hanging
- fileProblem probes the file with the bounded probe before realpath
- the thread map records its parent channel; a new channel starts afresh
- threadFor returns its failure instead of sharing this.last
- discord-notify: per-session token bucket (6 a minute), 429 RATE_LIMITED, plain line from codeman notify
- fileProblem probes the working folder with the bounded probe before realpath
- sendTest uses its own DiscordApi and leaves this.cfg alone
- drop the resumed-tab check from the typed hint (only Claude's field was read)
- first sessionRenamed per session records the name without a PATCH
- boot goes through ensureLoaded, so one gateway starts
- a thread created without an id reports the failure
Claude keeps the silent system-prompt hint (startupHint, on). Other CLIs are sent the typed message only with typedHint, which costs a model turn per tab.
Adds the codeman notify command, a startup hint (Claude via --append-system-prompt, other CLIs once on first idle), files saved from thread attachments into the tab folder, and --file uploads limited to the session folder.
Alerts for permission prompts, questions, idle and errors post into a per-tab thread; a reply from an allowlisted user is typed into that tab. Thread creation, thread cleanup on tab delete and pinging are configurable. POST /api/sessions/:id/discord-notify lets a CLI ask for the user. Setup is in docs/discord-bridge.md.
tmux reads a pane's directory from the process cwd, which is always the
resolved path, while workingDir keeps the spelling the case was created
with. For a workspace reached through a symlink every reading looked
like it was outside the workspace, so the browser sent each relative
link through the attachment route instead of the workspace routes.
Each session now resolves workingDir once in the background, bounded by
probePathKind() and a timed realpath(), and setCwd() writes a reading at
or under the resolved path back in workingDir's spelling. Until that
settles only a reading lexically inside workingDir is taken. An unknown
probe or a failed realpath leaves readings untranslated and retries
after WORKSPACE_REALPATH_RETRY_MS.
Also corrects two comments: cwd is written to state.json but never read
back, and a blank pane path is usually a pane whose program exited.
applyPaneExits() only applied the manager's directory when it returned a
value, so after a successful read a session that was split into several
panes, or was no longer on the socket, kept its stale cwd. The manager
already keeps its map across a failed or empty read, so the server now
applies its answer as given, undefined included, and setCwd() broadcasts
the clear once.
A blank #{pane_current_path} on a single-pane session (tmux could not read
the process cwd that tick) now carries the previous entry forward in
derivePaneCurrentPaths(), so only a split or unlisted session clears.
The server tests now drive the real TmuxManager with only the tmux read
faked. docs/api-reference.md documents SessionState.cwd.
The merged PRs (mostly #714's git fetch) added about 120 em-dashes in
comments, docs, test names and three settings strings. Each one is now a
comma, colon, semicolon or parentheses. The English settings strings in
index.html and their i18n.js keys change together, and the zh-CN value
for the fetch interval uses full-width parentheses instead of a double
dash. The one left is the regex in constants.js that matches a dash
typed as a word, which is behaviour, not punctuation.

The self-gate now says the skill reads saved Codex conversations offline outside a session; the staging
reference says only tagged input gets 409 during a guarded submit (the rest is held), and the API
reference notes a managed write past a full hold queue falls back to a direct write. Also: missing
reference rows, agent --help naming inspect/stage/submit, the tunnel opt-in in Remote Access, MCP wording.

readDockerCases() reads an unreadable or half-written docker-cases.json as [], so a fetch (which runs
repository hooks, and runs unattended on the interval) could run inside a Docker workspace. The fetch
paths now read it through a strict reader: the Fetch button answers a failed run (state 'error') and the
scheduler skips the tick, undoes its picks and logs once. The status and diff routes are unchanged.

Conflicts resolved by keeping both sides:
- CLAUDE.md (Agent CLI): #694's opening (an HTTP client, the experimental
agent-session-routes behind agentCoordinationEnabled) with #708's clause
on the directory spawn and its two refusals.
- docs/api-reference.md (codeman agent): #708's spawn paragraph and --json
shape, with #694's inspect/stage/submit in the verb list and the guarded
endpoints named before "adds no route for the other verbs".
- src/cli-agent.ts (@fileoverview): #708's quick-start / directory spawn
routes and #694's experimental routes in one endpoint list; the two
node:fs/promises imports (#708's realpath+stat, #694's open+stat) merged
into one.

Conflict in CLAUDE.md (Adding Features, App setting) resolved by keeping
both sides: #714's sentence that a setting the server acts on must be
synced, after the `.strict()` clause, and #719's mutateSettingsFile() rule
at the end of the bullet.

Conflict in src/web/routes/system-routes.ts (PUT /api/settings) resolved by
keeping both sides: #718's line that never stores an unauthorized
tunnelEnabled:true runs first, then #719's serialized mutateSettingsFile()
write replaces the inline read and plain writeFile.
test/routes/system-routes-tunnel-guard.test.ts: #718's new tests asserted
plain writeFile calls on settings.json. With #719 every write goes to a temp
file renamed over it, so the assertions read writes through a settingsWrites()
helper (writeFile contents keyed by their rename), and the concurrent-stop
harness applies a write and the stop at the rename.

- src/web/routes/session-routes.ts:2102: the guarded-submit 409 now applies to tagged input (clientId + seq) only; untagged input is held like a WebSocket frame. The raw write (:2228) goes through holdForGuardedLease and answers 200 once held (a send-and-wait reads `delivered` from the held write; a full queue releases the waiter and answers 409); a mux write takes its own turn in writeViaMux.
- test/guarded-lease-held-input.test.ts: real-Session route tests for an untagged raw POST during the lease (written after the Enter) and a held send-and-wait (delivered: true); both fail without the fix.
- test/routes/session-routes.test.ts + test/mocks/mock-session.ts: the 409 test now covers tagged input only; new tests for untagged raw (held), untagged mux (own turn) and a full hold queue (409); MockSession gains holdForGuardedLease/releaseGuardedLease and a lease-aware writeViaMux.
- src/session.ts:4787 (guardedInputHeld JSDoc) + write() + docs/architecture-invariants.md: write() refuses during the lease only, so cron's paste mode can land ahead of input still draining.
- docs/api-reference.md: the input route's 409 is for tagged input; untagged input is held.

- src/web/settings-writer.ts:110: export assertSettingsWritable(), the writer's own read-for-write rule run on its own
- src/web/routes/case-routes.ts:1860: an admin's rename checks settings.json before it ends any session or moves the folder, and answers 409 CONFLICT with the writer's message (placed before the session-starting check, so nothing is awaited between it and the lock)
- test/routes/case-rename-routes.test.ts:314: the torn-file pin now expects 409 CONFLICT (no stoppedSessions, like the other pre-checks)
- test/routes/case-rename-routes.test.ts:331: new test, a live session with stopSessions and a torn file: 409 CONFLICT, cleanupSession not called
- docs/api-reference.md: the Settings paragraph says an admin's rename answers this refusal as 409 CONFLICT before ending sessions
- src/hooks-config.ts:1161, src/prompt-cache-keepwarm.ts:341: comments describe the atomic writer, not an in-place rewrite

- docs/api-reference.md:1222: the tunnel status shape is { running, url, loginConfigured } (getStatus() returns only running and url)
- src/web/routes/system-routes.ts:1233: the unauthenticated-tunnel warning keys on !isLoginConfigured(), so it no longer fires in multi-user mode
- test/install-sh-invariants.test.ts:537: install.sh must not contain --allow-unauthenticated-tunnel either (it writes service argv as well as env)

The input lease is held across the awaited tmux Enter, so WebSocket frames
keep arriving while it is held. A tagged frame (seq N) was refused and its
seq rolled back, but the browser's WebSocket path does not wait for ACKs:
seq N+1 landed after the lease and moved the watermark past N, and the
redelivered N was then dropped as a duplicate. The keystroke was lost.
Input that arrives during the lease is now held and written in arrival order
when the lease is released, whatever the submit's outcome. A WebSocket frame
is applied and ACKed only once written; managed writes (writeViaMux) and
named keys (send-key) wait for their turn the same way, and a held write that
is still being sent holds everything behind it. A keystroke held before the
guard runs still moves the input revision, so it still invalidates the Enter.
The hold is capped per lease (256 inputs, 1 MiB): past it the WebSocket is
closed with 1013 and nothing later from it is applied, so the browser resends
every unACKed frame in order, and send-key answers 409 CONFLICT instead of
logging a tmux failure as INTERNAL_ERROR. POST .../input keeps its 409 for the
lease plus the held input's drain; its browser drainer is serialized.
Docs: correct the api-reference paragraph that said these keystrokes are
redelivered, and describe the capture fallback and the per-scope cursor cap
from the previous two commits in api-reference, architecture-invariants and
the changeset.
`codeman agent spawn` always sends its directory as an explicit
workingDir, so the server cannot apply its no-workingDir rule and
installs workspace hooks (and an injected skill) into ~/.claude when the
caller's cwd is HOME. A bare spawn whose cwd resolves to the home
directory now refuses with exit 4 before any request and names
`--working-dir ~`; an explicit `--working-dir ~` is still sent. Paths
are compared by realpath, so a symlinked HOME matches, and an
unresolvable HOME or cwd falls back to the resolved path without
throwing.
The directory-spawn --json shape now reads the same in the README, the
API reference, the wiki page and the changeset: `ready` when a
readiness wait ran, `readinessError` when that call failed, and
`startupError` when the start failed. A test pins all four.
The network acknowledgement that install.sh writes for every passwordless LAN install also satisfied the tunnel guard, so one click on the welcome screen's tunnel link published full terminal control to a public URL with no login and no confirm. The tunnel now needs CODEMAN_ALLOW_UNAUTHENTICATED_TUNNEL or --allow-unauthenticated-tunnel (carried by web -d and service install), and with no login the browser asks before every enable, reading a new loginConfigured field from GET /api/tunnel/status.
The guard is now decided once per request and required again where the tunnel starts, so a save that found the tunnel running can no longer restart it unguarded after a concurrent stop.
Closes#706
Quick-start saved lastUsedCase with an un-awaited, non-atomic read-modify-write, and the settings PUT, model config, case order, case rename, Ralph start and the boot tunnel reset each ran their own. Two overlapping truncate-then-write calls left one write's bytes over the tail of the other (the CI flake in test/quick-start.test.ts), and most writers then read the torn file as {} and wrote back only its own keys, erasing the rest of the user's settings.
All of them now go through one writer that runs one change at a time, replaces the file atomically, and refuses (409 CONFLICT) to overwrite a file that does not parse.
`execFile` signals the `git` parent only, so a fetch that times out can leave its http helper
still running, and on the interval that repeats every run with nobody watching. `runFetch` now
spawns `detached`, so the fetch and the helper it spawns share one process group, and the kill
is SIGTERM to the negative pid then SIGKILL `FETCH_KILL_ESCALATION_MS` later; the escalation is
not cancelled when the promise settles, because the caller is answered at the timeout while the
group is still dying. The output cap is kept, and the clone's slot queue is not needed here.
The tick is two passes: every enabled local session is collected by folder, a folder is due when
ANY session open on it is due, the folder is probed once for the group, and the run is published
to every session on it. A single pass decided by the order the sessions were read, so [long,
short] published only the short one and the 3600 s session's row never updated again while its
folder was fetched every 30 s.
`gitNonInteractiveEnv` writes BatchMode ssh as a default, not an override: `core.sshCommand` is
read inside the same slot and the same bound as the fetch it serves, and `fetchEnvFor` keeps the
repository's answer when it has one, because that is usually the setup that works on a machine
with several ssh setups. The `accept-new` host key it can write is stated next to the BatchMode
note: a prompt is stopped, a write is not.
The write claim is scoped to the Git panel and to the timer, with cloning and worktree management
named as the writes that happen when the user asked for them, and the zh keys sit with the group
of the UI surface their English string belongs to.
Tests: the process-group test proves the tree by group membership, because the helper is a
grandchild (`git fetch` runs `git remote-http`, which spawns `git-remote-http`) and because the
group is what the negative pid reaches, and it remembers each process once found instead of
re-scanning a group it had already emptied. The non-zero-exit test changed premises: `git fetch
--quiet` in a repository with no remote exits 0 on git 2.47.3, so resolving empty stdout there was
correct, and the case that has to reject is a remote pointing at a path that is not a repository.
The join test asserts after the run and does not await the request before the held run is
released, which would wait on the run the test is holding.
Stage now re-reads the pane after typing (every 50 ms, up to 1 s) and
issues a receipt only for a frame with the same generation, the input
revision its own write moved, and a composer hash equal to the
message's. Codex repaints 30 to 60 ms after the keys, so the first
capture was often stale and stage refused with the text already typed.
Every refusal after typing now says the message may be in the composer
and points at the Ctrl+U recovery. A visible-frame capture reads the
screen and the caret in one tmux invocation, with the old two calls as
the fallback.
Codex draws its suggestion popups above the composer and keeps the
footer, so a staged /stat verified and submit ran /status. Stage now
refuses a leading / or ! and a last word starting with @ or $ before
typing, and stage and submit refuse a frame with popup rows just above
the composer. The pattern and characters are registry data
(composerPopupLine, composerCommandPrefixes, composerCompletionSigils),
read from the codex 0.162.0 bottom_pane sources.
Submit waits until 250 ms after the staged keys: codex turns an Enter
within 120 ms of a typed burst into a newline. POST .../input answers
409 with its seq returned while a guarded submit holds the input lease,
instead of 200 for bytes it never wrote.
Also align the attribution memo comment with the code (a verified file
whose incremental scan fails is not re-walked, since the full walk
reads a superset), and list stage as a fromUser source in CLAUDE.md.
`codeman agent spawn --working-dir "$WT"` with WT empty (a failed
`git worktree add`, say) resolved '' to the caller's cwd and started an
editing worker in the caller's own checkout. An empty or
whitespace-only --working-dir now refuses with exit 4 before any
request.
The emitJson comment names the directory-spawn exception to "the
envelope's data": `{ sessionId, workingDir, created: true, ready }`.
Tests: unit (`''`, spaces, tab: exit 4, no calls) and through the real
argument parser and HTTP transport (nothing sent, exit 4).
Docs: README, api-reference, wiki, SKILL.md (plugin mirror synced) and
the changeset note the refusal.
The scheduler is the part that runs with nobody watching, so it is decided per folder
rather than per session: sessions sharing a folder are the same clone and share one run
that both see, `inFlight`/`lastRunAt` are keyed by the resolved folder, the schedule is
stamped when a folder is picked instead of when its run starts, and a tick is skipped
while the previous one is still going. The click route joins a run already going for the
same folder rather than starting a second fetch in one clone.
The tick keeps ONE bound for the git processes of the whole run and hands it to every
folder, and bounds its folders with a bound of its own: the same semaphore cannot serve
both levels, because a folder holding a slot would then wait for a slot its own fetch
needs. Both bounds are `FETCH_CONCURRENCY`, so the ceiling is unchanged. The bound claim
in CLAUDE.md, the `Limiter` jsdoc and docs/api-reference.md now describes it as it is.
Before anything is fetched the folder is probed with the bounded path probe, so a case on
a mount that stopped answering is skipped and never touched.
The rest of the review: the hooks are named as they really are (`reference-transaction`,
`pre-auto-gc` through the maintenance a fetch triggers, config commands such as
`credential.helper`) and `FETCH_CONFIG_ARGS` turns maintenance and gc off for an
unattended run; the claim that an agent in the same repository is not disturbed is
replaced by the ref-lock collision it actually is; the click route publishes its own run
as `trigger: 'click'`; `autoSaveGitFetch` uses `_apiJson` so a 400 shows the error toast
and applies the returned settings; and the two wording fixes.
Tests: the scheduler pins one run per folder, the two bounds, the probe before anything
runs, and that closing the session holding the override keeps the folder while another
session is still open on it; the route test pins the click publish and the join, asserting
the join before the held run is released — releasing first lets the run finish and clears
the lane, so the joiner would be entitled to its own fetch and the test would pass for the
wrong reason.
Fetch is the only git command Codeman runs that writes, and the only one that runs a
repository's own fetch-post hook, so it stays behind a click and off by default. The Git
status window's header row gains Fetch; App Settings -> Bottom bar gains the switch and
the interval, synced because the scheduler acts on them, and Session Options -> Git
overrides both per case. The scheduler reads settings fresh each tick, times the interval
from the start of a run, never overlaps runs, and re-checks the Docker and remote rules
every tick before any git runs. Nothing but remote-tracking refs moves: HEAD, the index
and the working tree are proven unchanged against real git while origin/main advances.
Tests: src/git-fetch.ts and the scheduler, the per-case settings route, the synced/display
setting split, the two new i18n rows, and the Fetch block of the Git status browser suite.
Gate inspect, stage and submit behind the synced agentCoordinationEnabled
setting (default OFF, App Settings > Cross-session features, zh-CN
strings). While off, all three routes answer 403 FORBIDDEN naming the
setting, checked before session lookup; the CLI verbs print it verbatim.
Remember the attributed Codex rollout per session and re-verify only its
head on later calls, rescanning only date directories not older than it
for a /new conflict. The first walk reads 1 KiB prefixes first, so a
store of 2,100+ unrelated rollouts still attributes.
Answer unexpected inspection errors with 422 OPERATION_FAILED and log
the session id and error code only.
Read the guarded composer glyph and footer from the CLI registry: codex
workDetect.promptGlyph and a new workDetect.composerFooterLine
capability, compiled through compileVersionRegex. Codex footer effort
words are one shared list with modelDetect.screenLine.
Fix the wiki API reference link, frame the versioning policy entry as a
case of the experimental rule, join the CLAUDE.md Agent CLI paragraph,
and update the changeset, skill reference and architecture notes.
`codeman agent spawn ""` (for example `spawn "$CASE"` with CASE unset)
used to launch a worker in the caller's cwd. Both case checks now test
`caseName !== undefined`, so an empty name reaches quick-start and is
refused by its schema as before.
Drop the `{ id }` fallback on the create answer: `POST /api/sessions`
answers `{ session: { id } }`, and the test fakes now use that shape.
Tests: an empty case name (unit and through the real argument parser
and HTTP transport), the claude `--ready` order create, /interactive,
wait-output on the created id, and a non-JSON failed start (id alone on
stdout, reason on stderr, exit 1).
Docs: the spawn mapping and directory-launch JSON shape in
docs/api-reference.md, the README and wiki `codeman agent` sections, the
cli-agent @fileoverview and the skill reference tables; reflow the new
SKILL.md paragraph (plugin mirror synced); the changeset notes the
local exit-4 refusal of an unknown mode for named cases.
docs/api-reference.md listed POST /api/cases/:name/rename in the Settings
table, whose introduction says every route in it answers 403 FORBIDDEN to a
non-admin in multi-user mode, and its paragraph said caseOrder and
lastUsedCase are always updated. Neither is what the route does (and what
CLAUDE.md, the wiki and test/routes/case-rename-routes.test.ts say): a
non-admin renames their own case (200), and only the server-wide
settings.json write is skipped (`if (isAdmin(req))`).
The row leaves the admin-only table (its body moves into the paragraph), the
paragraph says the route is not admin-only and that caseOrder/lastUsedCase
follow an admin's rename only, and a linked case's 404 for a non-admin is
spelled out.

The rename lock is checked once, in the Session constructor, but a session
reaches the server's map (where the rename route builds its list of open
sessions) only later, after the create awaits the owner's layout lock and a
fresh settings read (and, for POST /api/sessions, inferLocalCaseName). A
rename in that gap neither listed nor stopped the session, moved the folder,
and the create then registered a session whose pane starts with
`cd "<old path>"`, skipping the 409 requiresStop / stopSessions guarantee.
- case-rename.ts keeps a record of sessions constructed but not yet
registered (`noteCaseSessionStarting` / `caseSessionSettled` /
`isCaseSessionStarting`), with a 30 s TTL for one that never registers
(a failed create, a one-shot prompt), swept on every note and check.
- The Session constructor records itself (local sessions only, as the
route ignores remote ones); registerSessionWithLayout()'s register
callback, the boot-restore registration and stop() settle it.
- The rename route answers 409 CONFLICT with renameCode BUSY ("A session is
starting in this case") for a folder move while one is recorded at or
under the folder. The check runs in the same tick that takes the lock, so
every interleaving is either refused here or by the constructor. An
alias-only rename is not refused.
A create whose path was validated before the move but whose Session is
constructed after it is still the ordinary check-then-use race of any
create path; CLAUDE.md now says so instead of "nothing starts mid-move".
Tests: unit (record, settle, stop, TTL), route (BUSY, then requiresStop once
registered; alias-only unaffected) and an end-to-end WebServer test that
holds the create between constructor and registration (it fails without
the route check: the folder moves under the session).

Conflict in src/web/routes/session-routes.ts (the import block) resolved
