Michael GrundbergandClaude Opus 5.5 b80d47aff8 feat(session): close sessions whose agent exited cleanly (#486)
* fix(cleanup): keep .claude-images while a sibling session uses the same dir

cleanupSession() recursively removes {workingDir}/.claude-images. That
directory belongs to the working directory rather than to the session, and
several sessions routinely share one case directory, so closing one session
deleted the pasted images a live sibling still referred to.

The removal now runs only when no other live session has the same working
directory. A session that is itself being cleaned up does not count as live,
so two sessions of one case closed together still remove the dir.

Split out ahead of the exited-agent sweep for Ark0N/Codeman#446, which closes
sessions unattended and would otherwise make the loss routine.

* feat(session): close sessions whose agent exited cleanly (#446)

Part 2 of Ark0N/Codeman#446. Part 1 records an exited agent as
SessionState.paneExit. A session whose agent the user ended with /exit is
now closed through cleanupSession(), the same path the X button takes, so
finished sessions stop piling up on the board. The lifecycle log records
the reason as "agent exited cleanly (status 0)", and the conversation stays
resumable from the Resume list.

shouldCloseCleanlyExitedSession() in the new pure module pane-exit-sweep.ts
holds the rule. It closes a session only when all of these hold:

- The exit status is an explicit numeric 0 with no signal. An absent status
  is how a SIGKILL presents on tmux 3.2a, so it counts as unknown and the
  row stays. A non-zero status or any signal also keeps the row, with the
  exit code on the tab.
- Two authoritative pane reads agreed on that exit.
  TmuxManager.getPaneExitReadCount() counts them, and a failed, empty or
  skipped read neither confirms nor resets the count.
- No start, attach or relaunch is running for the pane.
  Session.paneLifecycleInFlight covers _setupOrAttachMuxSession(), whose
  dead-pane branch revives an exited pane on purpose, and restartCli().

setPaneExit() already scopes paneExit to local mux-backed sessions, so
remote, docker and direct-PTY sessions are never closed.

planRebootRestore() now refuses a record whose persisted paneExit is a
clean exit. That covers an agent that exited just before a reboot, before
the sweep reached it. A crashed agent's record stays eligible, like its row.

* fix(web): show "exited" on the phone overview and desktop home rail (#446)

Part 1 of Ark0N/Codeman#446 taught the tab strip and the rich rail rows
to say that a session's agent has exited. The phone overview and the
desktop home rail still said "idle", beside a green or pulsing dot.

_mobileOverviewExit() in mobile-overview.js is now the one rule for all
three surfaces, and _sidebarRichRow() uses it as well. It changes what a
row shows and leaves the row's state alone, because the state still picks
the section and the sort order. An exited row gets an "exited" pill, a
neutral dot and row accent, and a duration measured from when the server
first saw the pane dead. A pending permission prompt or question still
wins, as it does on the tab.

* fix(cleanup): close the gaps review found in the #446 sweep and image guard

Four fixes from a dual review of Ark0N/Codeman#446 part 2.

- The .claude-images guard compares canonical paths, so a sibling that
  reaches the same directory through a symlink keeps it. Its comment used to
  say that case only missed a deletion; it caused one.
- A detached session counts as a live sibling. DELETE ?killMux=false removes
  it from the server's map while its pane keeps running, so the guard now
  reads persisted records too, and exempts only sessions being killed rather
  than every session in cleaningUp.
- A session being closed refuses startInteractive() and startShell(). The
  /interactive route awaits listener setup before the start, and a start
  that raced the close could launch a CLI in a tmux session whose record was
  then deleted. A failed close clears the mark again.
- The clean-exit sweep tries each exit once, keyed by session id and the
  exit's at stamp, so a close that fails is not retried and logged every
  two seconds.

* fix(session): keep a clean exit that lands within 10 s of a pane start (#446)

A CLI that prints a startup error ("not logged in", a bad profile, a config
error) and exits 0 used to lose its tab, and the error with it, about 4 s
after launch. The sweep now keeps any clean exit that lands within
CLEAN_EXIT_MIN_PANE_LIFETIME_MS (10 s) of the last start, attach or relaunch
finishing (Session.paneStartedAt, stamped when _withPaneLifecycle ends). The
row stays as "exited (0)" for the user to read and close.

Verified on an isolated instance: a shell that ran `exit 0` 2 s after start
kept its row, one that exited after 13 s was closed.

Codeman maintainer cbd1fa639d fix(tmux): merge-time fixes for the exited-agent report (#466)
- docs/wiki/The-Dashboard.md: the tab-appearance table gains the exited
  state (muted dot plus an `exited (137)` badge) and explains the bare
  `exited` variant.
- The detailed sidebar and rail no longer pair the muted dot with an "idle"
  pill: an exited session's pill reads "exited" (neutral styling) and its
  since stamp measures from the observed exit. This is a label override on
  the row model, not a new state, so SESSION_ACTIVITY_RANK and the home
  screen order are untouched, and a pending alert still keeps its own pill.
  The row signature includes the flag so the incremental path repaints it.
- The exited badge is aria-hidden like its sibling badges, and the exit is
  appended to the tab's aria-label in both render paths through one helper.
- test/tmux-manager.test.ts re-adds the junk-trailing-field parser case
  against parsePaneRows.

Michael GrundbergandClaude Opus 5 9c286eeddf fix(session): persist an exit retraction, and let tests reach the watcher
Ten findings from a two-model review of this branch. Both reviewers cleared the
detection logic itself; everything here is a gap around it.

A route that starts a command in a pane now PERSISTS as well as broadcasts.
`/interactive` and `/shell` did neither before, and the pane-exit watcher cannot
cover for them: its next tick finds `paneExit` already cleared in memory,
reports no change and writes nothing, so `state.json` kept saying the agent had
exited for as long as the session stayed quiet. Nothing reads that record for a
decision yet, which is exactly why it had to be fixed now — part 2 is designed
to read it. The `clearPaneExitForNewPane()` docstring claimed its callers
already persisted; that claim was false for these two, and now says what the
caller owes instead.

The watcher's four guards were unreachable by any test. `refreshPaneExits()`
opened with `if (IS_TEST_MODE) return;`, so the read gate, the in-flight
suppression, the generation counter and the empty-read rule could each be
deleted with the whole suite green. The tmux call moves into `readPaneRows()`,
which a test subclass overrides — the shape `runRemoteReconnectTick` already
uses in this file for the same reason — and the test-mode gate moves with it, so
what a test cannot do is spawn a process rather than exercise the bookkeeping.
Each of the four guards now has a test that fails when it is deleted.

The muted status dot turned out to be a specificity fight on three surfaces, not
two. `.tab-status.error` was not excluded, so a session whose agent exited and
whose PTY-exit breaker then tripped lost its red dot to the mute — the state the
browser answers with a "restart it?" confirm, and a needs-you colour by the same
argument that protects the two alert classes. And mobile.css gives a `busy` dot
a 9px size and a green glow with `!important`, while `status` stays `busy` for a
pane whose agent died mid-turn, so a phone rendered a grey dot still wearing the
green halo beside a badge reading "exited". Both measured against the real
stylesheets, both now excluded, and the CSS test reads mobile.css too instead of
being structurally blind to half the problem.

Six comments said things that were not true. Two named the stats collector as
what replaces a restored reading, which is the opposite of the design. The
interval constant argued that 2000 ms keeps a read inside a tick, when the
5000 ms exec timeout means it cannot — which is why the in-flight guard exists.
`MuxSession.discovered` did not say the flag is permanent, though `saveSessions()`
serializes it. The empty-read docstring claimed a distinction that `|| true`
makes impossible. The invariants doc promised more than its drift test delivers.
And CLAUDE.md had no pointer at all, leaving its two hardest prohibitions
("never set `status: 'error'`", "never null the pid") only in the file it is
meant to route people to.

Michael GrundbergandClaude Opus 5 90fd0a5a15 fix(tmux): gate the pane-exit read, and mute the dot on the rich rail too
Four changes the maintainer asked for on Ark0N/Codeman#446 before merging.

The pane-exit watcher stays always-on, but a tick now costs nothing when there
is nothing to observe. `hasObservablePaneSession()` skips the tmux exec while
every session on the manager is one of the shapes `Session.paneExitApplies`
already forces to UNKNOWN: a remote SSH session (its local pane holds the ssh
client), a docker case (a `docker exec` into the container's own tmux), and a
record rebuilt from the socket (no provenance at all). The timer is untouched.
Skipping retracts nothing, for the same reason a failed read does not: the map
still holds the last real reading, and every path that puts a new command in a
pane calls `clearPaneExit()` itself. The two copies of that rule are pinned
against each other in `test/session-pane-exit.test.ts`, because drift between
them is silent in both directions.

`DEFAULT_PANE_EXIT_INTERVAL_MS` was already a constant beside the stats and
remote-reconnect intervals; its comment now says why the watcher owns its own
cadence and why the number is what it is.

The never-default-an-absent-status rule is written where `PaneExit` is declared.
It names `status ?? 0` as the thing never to write, and says that an agent the
OOM killer took would otherwise read as a user typing `/exit` — which is what
absent-stays-absent keeps a later clean-exit sweep away from. Nothing fails when
somebody adds that `??`, which is why the sentence is there rather than a test.

Checking the dot's specificity found a second fight, and it was losing. On the
tab strip the alert rules win as intended: a session that exits with a
permission dialog pending still renders red, and yellow for an idle alert. On
the rich vertical tab rail they did not — that rail's own `tab-state-*` dot
rules are (0,9,1) against the strip's mute at (0,5,0), so an exited session
there kept a full green dot AND the working halo beside a badge reading
"exited". The rail twin matches that specificity exactly and therefore must stay
below those rules in source order; it clears the halo as well, which the strip's
rule never had to think about.

`test/session-pane-exit-ui.test.ts` now resolves the real stylesheet in jsdom
rather than matching selector text: postcss collects every rule that paints
`.tab-status`, a real engine decides, and the tests read back the answer. Two
mutations were run against it to prove it has teeth — dropping the hand-written
alert exclusions fails three cases, and moving the rail twin above the state
rules fails one.

Michael GrundbergandClaude Opus 5 c67c130caa feat(web): mark a session tab whose agent has exited
The tab now reads "exited (137)" beside the session name, drawn from the
`paneExit` field the server publishes. `applyPaneExitBadge()` owns the DOM
work, called from the incremental render path — the only path a live session
ever takes, since going from live to exited adds and removes no tab and so
never reaches the full rebuild.

An unknown answer draws nothing. A death tmux could not explain reads "exited"
with no number rather than "exited (0)", so an unexplained death and a clean
exit do not look alike. A signal death reads "exited (signal 9)".

The badge carries `data-i18n-skip`, like the status pills: it is generated
text, `i18n.js` walks inserted content, and a dictionary entry added later
would fight the renderer, whose in-place comparison is against English.

The tab also carries a `tab-agent-exited` class that mutes the status dot. That
dot is drawn from `status`, which stays `idle` or `busy` for an exited pane as
the issue requires, so without this a green or pulsing dot sits beside a badge
saying the agent is gone — the first thing a tester asked about. `status`
itself is untouched, so this is a rendering rule only. The CSS excludes the two
alert classes by hand, following the convention the rich-rail dot rules
document: a dot turning red or yellow because a session is blocked on a human
outranks "the agent exited".

The tab keeps its click behavior. X still closes it, and nothing here closes,
sweeps or restarts anything.

`docs/architecture-invariants.md` gains the mechanism under "Session data and
lifecycle", where every comparable one already lives: what the tri-state means,
the four shapes it is absent for, why the watcher cannot ride the stats
collector, why an absent `#{pane_dead_status}` is not 0, and the three things
that must never happen to an exited pane.
