- runner._run_cmd: the write of the prompt file was outside the cleanup
and error handling that the exec had (merge review: claude H1, codex R1).
A failed write now removes the partial file and returns the same 126
failed submit an unstartable wrapper does, so the loop ends with rc 1
and no traceback. Test S4c.
- test S9 required the literal "File too large" in stderr; bash 3.2 on
macOS prints nothing for EFBIG, so the whole suite failed on this host
(agy, grok, codex R2). The contract asserted everywhere is rc != 0, no
leftover file and the portable diagnostic line; the libc wording is
checked on Linux only.
- the wrapper accepted an empty --prompt-file and registered an empty
prompt (claude H3); it is refused now. Test S1e.

Review of f5cadd9 (planner-reviewer-codex-01, R1): the compliance job's
registration failure was only logged, so a passing next round ended the
real loop process with rc 0. Compliance now returns 1 when it cannot be
registered or does not finish, as the correction step already does.
Re-adjudication and arbitration also return 1 when their job cannot be
registered; a registered job that yields no verdict keeps the designed
fail-closed fallback.
S4c (stubbed delegate_job, a fixture whose later rounds never pass) is
replaced by S3c: a real `python -m lib_py.loop` process whose wrapper runs
an executable that simulates the agents, refusing the compliance,
re-adjudication or arbitration registration while the next round passes.

delegate_job writes the prompt to a temp file under the control root's .mam/
and hands the wrapper --prompt-file; the file is removed once the wrapper
returns. An OSError from starting the wrapper becomes a failed submit (rc 126)
that the existing error branch logs, so the session-busy retry no longer
dereferences a missing result. A retry that yields no job id, and a
compliance job that cannot be registered, are now logged instead of silent.
The collector caps are documented as the size of the evidence a reviewer is
shown; delivery has no cap of its own any more. The loop skill notes that a
pipeline hides the loop's exit code.

Review R1/N1 (reviewer-grok-01, planner-reviewer-codex-01), reproduced before
fixing. The usage line and SKILL.md both promise "relative to the control
root", but parse_args did Path(...).expanduser().resolve(), which is relative
to the caller's cwd. The runner never chdirs to workspace_root, so the two are
routinely different - the documented recipe runs the loop from the control root
while the source root is a worktree.
Two ways it went wrong: a plan that exists only under the control root was not
found at all (exit 1), and a same-named file in the caller's cwd was loaded
instead, quietly putting an unrelated plan into the first implementation
prompt. That second one is the very failure #25 is about, reintroduced through
the option meant to replace it.
Resolve against workspace_root the way jobs_dir already does (Issue #21 R2);
pathlib's `/` leaves an absolute or expanded-home path untouched. Every earlier
test passed an absolute tmp_path, which is why none of them caught this: P3c
covers both failure modes with the control root away from the caller's cwd, and
P3d pins that absolute and ~ paths are not rewritten.

The --plan-file check landed on the one path a human is watching. The three
--plan-mode loads read a report written by another agent with nobody watching,
and had no content check at all: find_report only tests that the path exists.
An empty or whitespace-only report therefore blanked current_plan in silence.
Phase 2's `if self.current_plan` then flipped the prompt to self-planning and
the run finished rc 0, having paid for a planner job, a Creator challenge and a
refine job and thrown the result away. The escalation refine was worse: it has
no guard, so the correction prompt asserted "follow the updated plan below" and
carried nothing.
All four loads share _plan_text() now - a plan is a readable regular file with
text in it - and each caller says what None means. An empty initial plan stops
the run instead of demoting it, and an empty refine warns and keeps the plan it
already has, which is still good. Those two together leave the escalation
prompt unable to claim a plan it does not carry, so it needs no new branch.
Found by the Creator's challenge to the plan (job 0f63ac1d), sustained by the
Planner as revision 1.

Without --plan, Phase 1 resolved a planner session automatically and globbed
<workspace_root>/.agents/reports/<planner>/plan-*.md for the newest file by
mtime, handing it to the Creator as "the plan already agreed on". Both keys are
wrong: the report directory belongs to a session, not to this task, so other
issues' plans pile up in it, and right after a clone or checkout mtime is
checkout order. 47 such plans are committed in this repository, so an ordinary
run could silently implement against an unrelated design.
Reuse is explicit now. --plan-file <path> is the only way to load an existing
plan; it is resolved against the control root, checked before a single job
exists, and refused if the file is missing, not a regular file, unreadable or
empty (an empty file would quietly turn into a "no plan" prompt). It cannot be
combined with --plan, and --review-only warns and ignores it because no
implementation job is delegated there. The implementation prompt itself is
unchanged, so the Creator's contract does not move.
Phase 1 now says which plan it loaded and where from, or that it loaded none.
The legacy shell loop (MAM_LOOP_PY=0) loses the same auto-load and rejects
--plan-file rather than duplicating the check on a path that is on its way out.

- worktree_prepare.sh installs the same files deploy/install.sh does
(.agents/skills/multi-agent-mux-delegate-job/requirements.txt: paho-mqtt,
PyYAML) plus requirements*.txt. Without paho the loop wrapper, stop_session
and the subscriber tests fail in the worktree - seen as 4 suite failures
in a worktree without its own venv, all passing with one.
- review D1: a failed pip install removes the venv it half made, so the next
run recreates it instead of reporting VENV=kept (test w1c).
- review D3: the [worktree context] block's uncommitted-changes flag uses
--untracked-files=all like the guards.
- review D2: the create skill doc says the install needs the package index.

R1/R2: `git status --porcelain` honours status.showUntrackedFiles, so a
`no` setting in a submodule (or the worktree) hid untracked files from the
checks that justify worktree_remove.sh's single --force and from the review
snapshot guard (_dirty_submodules), which then approved content it never
captured. All three checks (lib_py/worktree.py, worktree_remove.sh,
runner._dirty_submodules) now pass --untracked-files=all. The source tree's
own snapshot was already safe: `git add -A` ignores that setting.
R3: worktree_prepare.sh no longer links .venv to the control root's. It
creates the worktree's own venv with the control root's interpreter and
installs requirements*.txt; a leftover link is refused (exit 1), a control
root without an interpreter is a warning (VENV=skipped); VENV= is printed.
Tests: w1 (real venv, kept on re-run), w1b (link refused / skipped), w6e
parametrised over the hidden setting for the post-stop recheck, w6e2
(hidden untracked file in the submodule and in the worktree blocks the
removal), l17 untracked-hidden / during-hidden (guard refuses before the
first review; a mid-round hidden file makes the round stale). Each new
case fails without the fix.

- review jobs' [워크트리 컨텍스트] points at the [리뷰 identity] path only (B-2);
remote re-adjudication gets a matching sentence (N-4)
- dirty/untracked submodule content fails the snapshot and makes a round stale,
regardless of submodule ignore settings (B-R1)
- with --worktree/--base and no reviewer, the creator self-review takes the
reviewer path: snapshot diff, evidence check, pre-promotion re-check and the
identity sidecar; NOT PASS still re-reviews without a correction job (B-R2/B-R3)
- snapshot diff failures keep the UNAVAILABLE marker (N-1); prune only when
worktree remove fails (N-3); the empty per-loop review dir is removed (N-5)

Active with --worktree/--base only; without them prompts, flow and promotion
are unchanged (a loop_id is recorded in the checkpoint either way).
- Every review round is pinned (B3): the source's HEAD and its working state
as a tree built through a temporary index (the real index/status/refs are
untouched); a dirty state becomes a ref-less snapshot commit on HEAD
(committed as mam-loop, not as the user). An untracked nested repository
cannot be pinned and is refused. identity = (loop_id, base, head, tree).
- Review isolation (B4): a detached review worktree of the snapshot under
TMPDIR (default), or `--review-isolation env` (the source root with env and
temp-dir instructions). Failing to open the tree refuses the round - the
isolation is never lowered silently. Trees are removed after the round and
on any exit (run() wraps the body; release_guard too).
- The reviewers' diff comes from the snapshot (B13):
diff_collect.sh takes an optional head commit for a commit-to-commit diff;
its two-argument form is byte-identical.
- Stale rounds (B7/B8): after the round the source is measured again; if it
changed, the round's approvals are discarded and the next iteration
re-reviews without a correction job (last iteration: rc 1). Only the last
non-stale round's PASSes are promoted.
- Records (B9/B15): review_rounds in the checkpoint with per-reviewer
transport/evidence, and report-<jid>.identity.json next to each promoted
report: evidence review-tree | source-tree | diff-only.
- Pre-promotion re-check (B10): a source changed after approval is not
promoted (rc 1).
- Remote reviewers (B14, Creator challenge 91c81095): they cannot reach this
host's review tree. Checked before anything is delegated: refused by
default; `--remote-review diff-only` admits them with the snapshot SHAs and
diff as their only evidence (no local path in their prompt), and refuses a
round whose diff is truncated or unavailable.
- run_loop.sh accepts both options (usage identical to the runner's); the
legacy shell loop refuses them before the lock.
Tests tests/test_issue21_loop_b.py L1-L16 (22).

Review 9a1adb46 (planner-reviewer-codex-01):
- R1 [P1] lib.sh new-session: a forwarded binding reached the agent as
arguments. With env flags the idle-pane branch prefixed `env K=V ...` to
the command that `herdr agent start ... --kind <agent> -- <args>` passes to
the agent executable. An idle pane is now reused only when no environment
has to be set; otherwise the pane is created by pane split / workspace
create, which take --env. The dead `env` prefix code is removed (its
send-text fallback would have typed the same line).
- R2 [P2] runner: a relative MAM_JOBS_DIR is resolved once against the
control root, the way the wrapper (cwd=workspace_root) reads it, and that
absolute dir is used for delegation, wait, report lookup and cleanup.
- R3 [P2] stop: the row's control_plane.delegate_job_logs_dir is restored
(exported unless the caller set DELEGATE_JOB_LOGS_DIR), so the
cancellation history lands in the row's audit-log root.
Tests: T3-1 and T3-3 now assert that the binding arrives as --env on the
pane-creation calls and that no env/K=V token follows `--` in agent start
(fresh and reused pane); T3-4c (audit root on stop) and T2-15 (relative
MAM_JOBS_DIR) are new. The design doc's compatibility table and a create
comment no longer describe the removed idle-pane env path.

- --worktree <path> (CLI over MAM_LOOP_WORKTREE): the source root. Only the
diff, base, head and the empty-set check use it; the wrapper, registry,
checkpoint, loop guard, promotion and cleanup stay on the control root. The
collector is the control root's diff_collect.sh (never the worktree's
unreviewed copy), its arguments shlex-quoted. Validation: an existing
directory, the top of its working tree, the same git common dir as the
control root (".git" is resolved against the directory it came from).
- --base <ref> (CLI only, no env - a stale sha would silently widen the next
range): resolved to a full sha, must be an ancestor of the source HEAD.
- --review-only: requires --base, refuses --plan; Phase 2 is skipped and
logged; correction and comply jobs still go to the creator.
- With --worktree or --base every delegated prompt starts with a context
block (path, branch, base and its origin, head, base..head commit count,
uncommitted changes); without them prompts are byte-identical. All call
sites in run() go through one _dispatch helper.
- Fail-closed guard (only with --worktree/--base): before each review round,
self-review included, an empty change set or one git cannot determine
(exit codes, never output parsing) ends the loop with rc 1 instead of
asking for reviews. This closes the fail-open where a loop started after
an out-of-loop commit sent reviewers "(no changes since base commit)".
- The runner honours MAM_JOBS_DIR and passes --registry-dir to the wrapper.
- run_loop.sh accepts the three options; the legacy shell loop
(MAM_LOOP_PY=0) refuses them before the freeze and the loop lock.
Tests T2-1..T2-14.

Contract (no new event types): heartbeat every N s (automatic timer),
unresponsive after K x N s without an event, `started` within T s of the
injection, retained per-job state, and a remote transport.
- registry: heartbeat_sec / heartbeat_misses / ack_timeout_sec / transport
fields; idle_timeout_sec derives K x N unless explicit (defaults 30/4/60
keep the historical 120 s idle window).
- heartbeat.py + publish_event --heartbeat N: detached fixed-cadence timer
publishing signed `progress` heartbeats (threaded wire publish, local
record first); stopped by the terminal event via pidfile, by re-dispatch
and by lifetime. Terminal events refuse --heartbeat.
- publish_event: retained `<prefix>/state` (status, last_event, seq, HMAC)
sent on the same connection after every event (--no-state to skip);
publisher.publish_raw takes extra messages.
- job_subscriber: subscribes the state topic, recovers terminal status from
retained state, resets idle on any accepted message, records seq_gap and
reconnected in the audit log, idle budget before the first event is
T + K x N (--ack-timeout), --remote mirrors started/terminal events into
the registry through the transition boundary.
- lib.sh send_keys_safe: an accepted-but-unconfirmed submission is confirmed
by agent_status working or the job's own `started` (_sks_job_started);
pane change and busy token are no longer delivery signals.
- wrapper: --heartbeat/--heartbeat-misses/--ack-timeout (MAM_* env),
injected start command arms the timer, brief states the contract,
_wait_started (registry / events.log / subscriber log, bounded by T and
the wall clock) replaces the 10 s inject grace, R1 grace uses only the
on-disk event age (herdr/pane logged once as a diagnostic),
remote:<name> sessions skip preflight/idle/pane and dispatch over the
broker (remote_dispatch).
- remote.py (+ scripts shim): signed retained dispatch (MAM_DISPATCH_SECRET)
and a runner that mirrors the job into its own registry with the
orchestrator's identity, publishes started --heartbeat, runs --exec and
publishes the terminal event.
- loop runner: passes MAM_HEARTBEAT_SEC / MAM_HEARTBEAT_MISSES /
MAM_ACK_TIMEOUT_S through; YAML rows with transport: remote delegate as
remote:<name>.
- docs: MESSAGING.md 2.5 contract + remote transport, delegate-job SKILL.md,
registry.md, loop SKILL.md.
- tests: tests/test_issue18_liveness_contract.py (16); issue 14 pane-signal
tests flipped to started-based; issue 6 working-agent tests acknowledge
with started; CLI snapshot/help captures refreshed.
