On codex-cli 0.162.0, with 0.163.0 released, every launch first shows the
"Update available" prompt, and choosing Skip leads to a variant of the
workspace trust prompt: "2. Back to Agent Command Center" over the key-hint
row "enter continue · esc back". The pattern only accepted cancel,
interrupt, quit, answer or all as the closing word, so a fresh git repo
launched from Codeman sat on that trust prompt reading idle, with no red
alert and no blocked signal (measured live on a throwaway instance).
Adding "back" is safe because the hint row must still START with one of
the anchored hints ("enter continue" here): the popups the user opens at
the keyboard (/model, /permissions, /review, Implement this plan?) end in
"esc back" too, but their row starts with "enter select", so they stay
unmatched, as every existing negative fixture confirms. The new fixture is
the live capture with the scratch path replaced.

While a codex dialog was up, the session re-read its screen every 2 s with
a synchronous `tmux capture-pane`, for as long as the dialog stayed up. That
read costs about 8 ms of blocked event loop (measured 2026-10-14), and an
approval can sit unanswered overnight: 1,800 execs an hour per waiting
session, measured as 300 in 10 quiet minutes in the unit test.
A dialog leaves the screen only through a repaint, and tmux sends every
repaint to the session's client as PTY output. So while the last reading
saw the dialog and nothing has been drawn since, it is still up and the
read is skipped; a safety-net read still runs every 30 s
(BLOCKED_QUIET_RECHECK_MS). The clear keeps its 2 to 4 s latency, because
the answer itself is output. Never skipped once a reading has missed the
dialog: tmux updates the pane before it sends the repaint, and the
confirming read must not wait for output that may already have arrived.
The session-state tests now change the fake screen the way a real pane
changes (with output), and two new tests pin the skip and the confirming
read (the second fails with the guard removed).

Codex is the one CLI Codeman launches with its approvals on by default, and
it declares `hooks: 'none'`, so nothing tells Codeman it stopped to ask. A
codex session parked on "Would you like to run the following command?" read
as plainly idle, and one parked on a question read as WORKING, because the
question's own key hints end in `esc to interrupt`, codex's working line.
This adds a generic, optional registry field,
`capabilities.workDetect.blockedLine` (plus `blockedLines`, the window), and
the session state that reads it:
- `isBlockedScreen()` (session-activity.ts, pure) joins the last
`blockedLines` non-blank rows of a capture and tests the pattern once, so a
pattern can demand several markers and anchor the dialog's footer on the
end of the window.
- `Session` reads it off the same capture the idle confirmation already
takes, emits `blockedChanged`, and exposes `screenBlocked`. It raises on
one reading, and while a dialog is up re-reads the screen every 2 s,
because answering resumes the turn and a busy pane would not reach the
settle path again until the turn ended. It clears only after two readable
captures in a row without the dialog, so a capture taken mid-repaint cannot
clear and re-raise it; an unreadable capture changes nothing. A blocked
screen wins over the working line in the same capture.
- The pattern goes through `compileVersionRegex()` in both the schema refine
and at use (lazily cached), like every other config regex.
Codex's pattern was measured on a live codex-cli 0.162.0 pane on 2026-10-14
(`-a on-request -s read-only`, widths 200 down to 36): it needs a `› N.`
option row and then the dialog's key-hint row as the last row, allowing for
that row to wrap below about 60 columns. Command, edit and network-escalation
approvals, single and multi-question dialogs and the startup trust prompt
match; the idle and working views, menus the user opened (`/model`,
`/permissions`, `/review`), the composer holding the dialogs' words and a
transcript quoting them verbatim do not. `Implement this plan?` is left out
on purpose: its footer is the same as `/model`'s and the turn has ended
there. The captures are kept as fixtures (trailing whitespace trimmed, the
scratch path replaced).
Nothing consumes `blockedChanged` yet; the next commit raises the alert.
