Claude Code answers an exhausted model budget INSIDE the turn ("You've
reached your Fable limit. Run /usage-credits to continue or switch models
with /model.") and then sits there with nothing to write. The reviewer never
produces a report, so `runTurn` waited out its full 40-minute deadline and
reported a bare "timed out after 40 min without a report", which reads as a
hung reviewer rather than an account that needs attention.
Measured on 2026-09-08: #388, #393, #394 and #377 each lost 40 minutes this
way, and because every attempt counted, all four reached MAX_AUTO_RETRIES and
would NOT have been picked up again once the budget returned. One spent
afternoon quietly took the whole queue out of service.
`findModelLimitNotice()` reads the notice off the pane and `runTurn` returns
a new `limit` outcome instead of waiting. It is consulted in exactly two
places, both of which mean "the turn produced nothing": on a stop where
`isDone()` is still false, and on each timed-out wait slice. A review that
merely discusses usage limits in its own findings therefore cannot be
mistaken for one that hit the wall, and the pattern matches neither the model
name nor a straight apostrophe, since the pane renders a typographic one and
every model prints the same sentence.
A spent budget is an account condition, not a bad PR, so it no longer spends
the per-head retry budget: the queue resumes by itself when the budget does.
Telegram now names the cause and the file to change.
Tests use the pane captured verbatim off the run that lost the 40 minutes.

Observed on the first live merge (#383 via the Telegram button): runConfirmed
announced the merge and the scan five seconds later announced it again as a
closed PR. The scan now stays quiet for PRs the bot itself merged or closed,
and a merge of a `merge-with-fixes` verdict reminds that merging applies none
of the listed fixes.
A failed review used to be re-queued on every scan with no limit (two PRs
failed once each and were retried fine, but a head that keeps failing would
cost a session every ten minutes forever): three failures on one head now
stop the automatic retries until /review N or a new push. The failure notice
carries the reviewer's last message, so "finished without writing
report.json" says what it wrote instead.

Maintainer tooling in scripts/pr-bot/: a daemon (systemd user unit
codeman-pr-bot) that lists open PRs with gh, reviews each head commit once in
a Codeman claude session (`prbot-<n>`) running in a private `git clone
--shared`, and sends the verdict, ranked findings, checks and a recommendation
to Telegram with action buttons. Merge, close, post-comment and approve-CI
happen only from a Telegram command or button plus a confirmation tap; the
bot never writes to GitHub on its own. The Telegram token and chat id come
from the existing notifier bot's env file.
Verified live: three PRs reviewed end to end (383, 363, 368), reports
delivered with buttons, reviewer sessions on the pinned model. Findings
along the way, each fixed and documented: a linked worktree inherits the
main checkout's model pin (hence the shared clone), undici's 5-minute header
timeout cut off the first review, gh was missing from the service PATH, and
the periodic scan orphaned an in-flight review's record.
typecheck/lint/format now cover scripts/pr-bot; tests in
test/pr-bot-{report,state,commands}.test.ts; guide in docs/pr-bot.md.
