Michael GrundbergandClaude Opus 5 05c788ce9d fix(watching): close the review findings on the label and its window
A dual review (Codex CLI and Claude's code-reviewer, same diff, same brief)
found the trust boundary weaker than the comments around it claimed. Eleven
findings, all applied.

The two blockers were both about who can write the row the label is read from.
Claude's window covered two rows, and the second one is the status line, whose
command a session running with permissions bypassed can write into its own
`.claude/settings.json` — so an agent could print `· 1 monitor ·` onto a row of
its own and silence its own idle alert. The default window is one row now, which
is the footer and nothing else, and the constant says why. Separately, the label
reached `data-tab-meta-sig` unescaped while the row is installed with innerHTML,
which is an injection sink for any config-supplied pattern whose capture group is
permissive; it goes through escapeHtml() like every other untrusted string in
that file.

The Codex entry could not be fixed the same way, and now says so. Its row is
third from the bottom only while a terminal runs; with none running that slot
holds the last row of the transcript, so matching the complete row (with the
`/stop to close` tail, window narrowed to three) raises the bar without closing
it. What contains it is `hooks: 'none'`: no hook event from a codex session
reaches notePrompt(), so a forged label costs a wrong badge and cannot quiet an
alert. The registry comment, `docs/cli-registry.md` and the test all state that
rather than claiming a guarantee the code does not have.

Also from the review: the TUI header badge no longer counts an acknowledged
item, which was the same gate the classifier fix already went through and was
wrong for human acknowledgement too; the TUI approval card reads the quiet
reason and drops to a new `info` tone instead of asking for a reply; the badge
carries an aria-label, because the phone it was built for has no hover target;
the schema refuses `watchingLines` without a `watchingLine`; and the pattern and
its window are resolved together rather than one memoized and one not.

Documentation moved with it. The mechanism now lives in
`docs/architecture-invariants.md` with CLAUDE.md keeping the rule and a pointer,
`docs/wiki/Notifications-And-Approvals.md` tells users why a session stopped
buzzing, and both that page and the changeset name the limitation neither did
before: a question asked in plain prose is not a dialog, so it is silenced along
with the false alarms while background work runs.

Verified live again after the narrowing, on an isolated beta: a Claude session
reported `1 monitor` and took its idle prompt acknowledged, and a Codex session
reported `1 background terminal` against the full-row anchor.

Michael GrundbergandClaude Opus 5 64c288a683 feat(codex): read Codex's own background-terminal row
Codex states background work too, and it says so in a different place. Claude
writes `· 1 monitor ·` on the last row of the screen; Codex pins
`1 background terminal running · /ps to view · /stop to close` ABOVE its
composer, which puts that row third from the bottom once the status line and
the composer are counted.

So how far up the screen to look is now per-CLI data as well:
`capabilities.workDetect.watchingLines`, bounded to 1..8 by the schema, and
defaulting to Claude's two. That bound is the point. The window is half the
injection guard, since every row it adds is another row the agent itself may be
able to write, and the label is what silences an idle alert. The other half is
the anchor, and Codex's is ` · /ps to view`: chrome naming a slash command only
the CLI can offer, so a session that writes "I left 1 background terminal
running for you" into its own output matches nothing.

Measured against a live codex-cli 0.154.0 pane rather than read out of a
binary. The row appears when the terminal starts, follows the composer down as
the conversation grows, and is gone after `/stop`. Verified end to end on an
isolated beta: the session payload carried `watching: "1 background terminal"`
and the badge rendered with it, and both cleared when the terminal stopped. The
fixtures in the tests are that capture verbatim.

Codex has no hook signals, so no idle prompt and no false NEEDS YOU row: for a
Codex session this is the badge alone, which is the case the maintainer said a
registry field could cover and a hook never could. Cross-CLI tests pin that
neither pattern fires on the other's screen, and that a CLI declaring nothing
still reports nothing.

Michael GrundbergandClaude Opus 5 74884a20eb feat(approvals): let a watching session keep quiet, and fix the tui gate
The badge alone left the row in NEEDS YOU, which is the thing the issue was
about. The fix is the alert that does not fire.

An idle prompt from a session that is watching its own background work now
opens ALREADY acknowledged. `hook-event-routes` passes `Session.watching` to
`notePrompt()`, which sets `acknowledgedAt` and records why in a new
`acknowledgedReason`. Nothing new suppresses anything: `acknowledge()` has
always meant "the alert this prompt armed is spent", and the prompt itself
stays pending, answerable and available as Read My Mind context. A wrong label
therefore costs a card that does not blink, never an alert that was never
created.

Every surface follows from that. The broadcast carries the reason, so a live
page declines to arm the tab alert and raises no desktop notification. The push
is skipped, since a false alarm is hardest to ignore on a phone. A reloading
page reads `acknowledgedAt` in `seedApprovals()`, which it already did. And
`classifySession()` now reads it too, which is a pre-existing bug fixed here:
acknowledging on one device cleared the alert everywhere except `codeman tui`.
It re-arms for free, because the next idle prompt supersedes the item and is
built fresh. Only `idle` is eligible, so a dialog that blocks the agent still
goes red whatever else it started.

The label is pane-derived and therefore prompt-injectable, so it is now read
from the last two rows of the screen only, with Claude's pattern anchored on
the `·` its footer joins items with, ANSI-stripped and length-capped at the
source. An agent that prints `· 1 monitor ·` into its own output finds no
match.

Verified on an isolated beta: a session that armed a monitor took its idle
prompt acknowledged with no alert on any surface, wore the badge, and showed
"quiet, watching 1 monitor" on its still-answerable card; the same session with
the monitor killed alerted normally on the next prompt. `test/watching-no-alert.test.ts`
pins both directions across all four surfaces.

Michael GrundbergandClaude Opus 5 3f2cde2db7 feat(session): say when a session is watching its own background work
An agent that arms a monitor, backgrounds a shell or hands a task to a
cloud session is told to end its turn. The pane then falls quiet, Claude
Code's idle_prompt notification arrives a minute later, and every surface
files the session under NEEDS YOU with nothing for a human to answer.

Claude states what it is still running on the last row of its screen
(`⏵⏵ bypass permissions on · 1 monitor · ← for agents`). That row is now
`capabilities.workDetect.watchingLine` in the CLI registry, guarded by
compileVersionRegex() like every other config regex, and the idle probe
reads it off the capture it already takes: `watchingLabel()` in
session-activity.ts searches the last five lines only, so a session that
PRINTS "1 monitor" is not mistaken for one running it.

The label lands on Session.watching and rides toLightDetailedState() out
to every surface. The phone overview, the desktop home rail and the rich
sidebar rows wear it as a `watching` badge in the accent colour, beside
the state pill and never in place of it: an agent can arm a monitor and
ask a question in the same breath, and only the pill says which.

Verified end to end against a throwaway session on an isolated beta
instance: the payload carried `watching: "1 monitor"` once the turn
ended, the badge rendered next to a yellow `waiting` pill, and both
cleared when the monitor died.

Codeman maintainer b03780dfd2 fix(session): decide working/idle from the pane, not the composer redraw
Every working Claude session reported `status: "idle"` about two seconds
into its turn. Measured on live workers: two sessions mid-tool-call at 13
and 17 minutes both read `idle` while their panes showed
`✻ Actualizing… (13m 23s · ↓ 47.5k tokens)`.

Two things had drifted apart:

1. The working indicator changed. Claude animates the glyph through
   `· ✢ ✳ ∗ ✻ ✽` and randomizes the gerund per turn, so neither
   SPINNER_PATTERN (braille, no longer drawn) nor the keyword list
   (Thinking/Writing/Reading/Running) matches a turn anymore.
2. A `❯` sighting is not the end of a turn. Claude redraws the composer
   roughly once a second all the way through one, and that redraw armed
   the "2s later, call it idle" timer.

Matching the new status line in the STREAM does not fix it either: tmux
ships partial repaints, so the complete line reached the PTY about once
every 20 seconds while the `❯` arrived every second.

So the decision moves off the stream:

- An unbroken run of repaints marks a turn as started. Sampled once a
  second for 12s over six live sessions, the two working ones produced
  output in 12/12 windows and the four idle ones in 0/12. Pure helpers in
  session-activity.ts carry the thresholds.
- Idle now needs the pane to go quiet AND the screen to agree.
  `_confirmIdle()` asks tmux what is rendered (new `capturePaneText()`,
  one plain `capture-pane`, floored at 1.5s per session and only ever at
  a transition) and re-checks every 5s while the screen still shows work.
  A turn can sit silent for tens of seconds inside one tool call, so
  silence alone proves nothing.
- The same screen check vetoes keystroke echo, which is a steady stream
  of repaints too but is not work.

CLAUDE_WORKING_LINE_PATTERN matches the `… (elapsed)` shape rather than
the glyph, because the FINISHED line (`✻ Cooked for 2m 49s`) carries the
same glyph and would otherwise pin a session at working forever.

Claude mode only. An external CLI has no `❯`, so nothing would arm the
confirmation and such a session would latch busy.

respawn-patterns.hasWorkingPattern() had the same blind spot (its gerund
list cannot see "Actualizing"), so it takes the pattern as an extra
signal. That can only make respawn less eager, never more.

Idle now lands about 3 to 5 seconds after a turn ends instead of 2
seconds into one. Verified end to end against a live worker, sampled
against the CLI's own "esc to interrupt" footer as independent ground
truth: busy for all 25s of a turn, idle 3s after it ended.
