- R1 (P1): without rules the input region runs from the last prompt line to
the end of the pane; only a last line matching the adapter's footer pattern
(codex: ` <model> · ~/<cwd> · …`) is dropped, so a draft on a second line
keeps the nudge withheld.
- R2: while the synchronous submit runs, a relay thread finds the job it
registers (same session, created since the submit) and prints its
stalled:/stall_watch: notices; before, they appeared only after the job.
- R3: the broker-unavailable disk wait that runs into the deadline is the wall
clock: wall_clock_timeout (caller rc stays 3).
- R4: a state_change_seq change seen right before the judgement restarts the
idle window (decision 9: S seconds of continuous idle).
Regression tests are the reviewer's reproductions, each with its passing
twin; the wrapper-level #30 tests now use this environment's broker instead
of the #18 harness's public default.

lib_py/stall_watch.py runs beside the wrapper's subscriber for a local herdr
job (started after delivery, stopped when the subscriber ends; MAM_STALL_WATCH=0
turns it off). It follows `herdr agent wait` transitions and publishes only
`progress` events through one publisher; it has no path that closes a job.
- blocked: `stalled:blocked <detection line>` once per episode, never answered.
- idle for MAM_STALL_IDLE_S (600) with no background descendants of the agent
pid (pane process-info + /proc; adapter resident_children and the heartbeat
timer excluded) and an empty input box: `stalled:idle` and one nudge.
- input box judged from adapter facts measured on herdr 0.9.1 (codex '›',
grok frame '│', opencode '┃' block + stop pattern); the whole-pane fallback
is gone. No facts: withheld + `stall_watch:input_check_unavailable` once;
never empty for 3 x S: `stall_watch:input_never_empty` once.
- herdr failures are not "no event": warning + `stall_watch:herdr_unavailable:
<code>` (or agent_not_found), backoff, rc 2 after MAM_STALL_HERDR_FAIL_S
(120); the wrapper prints the watcher's last lines.
- remote and human jobs are skipped with one log line.
- agent_status_reliable is an adapter field; false turns idle judgement off.
- the loop runner relays stalled:/stall_watch: notices once each.
- scoped_env drops a pane-inherited workspace scope for name lookups (#34 rule).
The module sits at the top of lib_py: delegation and loop may not import the
agent adapters (their sibling-import rules). Idle pane captures of the five
CLIs are fixtures; the mock herdr answers process-info in the real shape.
