GodopuandClaude Opus 5.5 bf0f5c1014 fix(issue-30-33): review 5ec8ef33 - a multi-line codex draft is not an empty box, blocked notices reach the loop while the job runs, and both clocks are labelled on every close path
- 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.

"""
Extracts the input area text of a pane, using only the agent adapter's facts
(issue #30, measured on herdr 0.9.1 captures in tests/fixtures/panes):
1. an `input_block_prefix` -> the last contiguous block of lines starting
with it, prefix removed, cut at the first `input_stop_pattern` line;
2. two or more `input_rule_pattern` rules -> the lines between the last two;
3. an `input_prompt` -> from the last line starting with the prompt to
the end of the pane, minus a last non-blank line matching
`input_stop_pattern` (the status footer). Every other line below the
prompt line is input: a multi-line draft is never cut to its first line.
Then `input_frame_chars`, the prompt and the placeholder are stripped. There
is no whole-pane fallback: a pane with none of these shapes has no input
region and yields a non-empty "unknown" result rather than a guess.
Raises ValueError for agents without input area facts (like hermes' peers).
