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.

Review of 4176d75 (planner-reviewer-claude-01, N1): _cmd_scrub_secrets chose
records by the presence of broker.password, not by its value. The old
to_registry_block wrote "password": null even for an unauthenticated broker,
so on this repo's registry (901 of 903 records carry the null key, none a
real password) --dry-run reported "would scrub 901 record(s)" and a real run
would rewrite every one of them while holding the registry lock.
- registry.py: select on broker.get("password"); an empty key is no secret,
and _atomic_write_record drops it on the record's next write anyway
- tests: the migration test gains a legacy "password": null record that must
be neither listed nor rewritten (fails on 4176d75 with "would scrub 2")
- VERSIONS.md v4.4.4 item 2 and registry.md now describe the stored-value
rule

Issue #12 - MQTT_PASSWORD was copied into every job record, which any
sub-agent can read. BrokerConfig.to_registry_block no longer persists it;
broker_config_from_job layers the password back from the environment
(.mam.env) at connect time, so publish_event still connects from the record.
_atomic_write_record scrubs broker.password from any record it writes, and
`registry.py scrub-secrets [--dry-run]` migrates an existing registry.
auth_token/dispatch_token stay: the agent's own publish_event needs them.
Issue #8 - update.sh restored the pre-update asset_hashes.txt and version.txt
over the installer's fresh ones, so version.txt named the previous commit and
remove.sh backed up every pristine updated file as "locally modified". The
success path now keeps the installer's stamps and only merges install_state
keys the re-install did not write (gitignore_created); the failure path
still restores everything verbatim.
Issue #7 - the shim's new-session took the first same-cwd pane, always found
the full first workspace, judged it overflow and opened another workspace per
agent (4 + 1 + 1). It now walks every same-cwd workspace in pane order and
takes the first with an idle pane or room in its 2xK grid; a workspace is
created only when all are full (4 + 2).
Tests: test_issue7_workspace_packing.py (3; the mock herdr gains an opt-in
per-workspace 2x2 geometry), test_issue8_update_state.py (1, real
install+update cycle), test_issue12_registry_secrets.py (4); registry CLI
snapshot and help capture refreshed for the intentional scrub-secrets
subcommand; registry.md documents the broker block.

Records the measured numbers and syncs every document that names the
delegation script paths, then bumps the framework to 4.3.0 in the three-way
lockstep (lib.sh, VERSIONS.md current + matrix, eight SKILL.md frontmatters).
phase1-benchmark.md carries both arms. The deterministic fake transport is what
CI asserts on: 50 publishes cost 50 connections one-shot and 1 persistent, p50
54.813ms -> 0.002ms. The real broker run is informational, since the PoC
default is a public broker: p50 1892.728ms -> 275.992ms, about 85% off.
It also corrects the plan's own estimate rather than repeating it. D8 predicted
the new shell path would drop from 3 forks to 2; the implementation is still 3,
because keeping the `_delegate_script publish_event.py` lookup is the only
thing that produces the "missing script tree does nothing" non-fatal contract
that C-02 pins. Saving that fork would change the contract, so it is deferred
to phase 4 rather than taken quietly.
SKILL.md gains the context table saying which tree wins where, so an operator
reading it knows a frozen loop runs frozen delegation code. The script paths in
every document remain correct and every quoted command still works verbatim.
