GodopuandClaude Fable 5.1 e629cc137f fix(issue-12,8,7): keep broker password out of records, keep fresh install stamps, pack sibling workspaces
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.

Refs #12 #8 #7

GodopuandClaude Opus 5 8adbe2245c docs(issue-5): phase 2b scenarios, operations note and task checklist
Three scenarios join the contract set, so the fifteen vectors now cover an
unproven side effect, an undecidable attribution, and an agent whose state goes
unreadable in the window between finalization and notification. All fifteen
match their expected decision.

The side-effect case needed a decision about layering. Authoritative enforcement
belongs in manifest verification, which has the job record and therefore knows
what was declared; the policy honours an explicit negative from the collector so
the case is expressible as a vector. Absence is not read as proof there, because
the manifest check is the layer that fails closed on missing evidence.

The operations note records why the agent declares and the reader re-derives,
the three gates and why the backend allowlist can only be narrowed, the
notification transaction, and the rollback.

It also records a deviation from my own plan. §D2 asked for reviewer sign-off
before promoting an attempt id into the record, since that changes a contract
phase 1 froze. Measurement during implementation showed the change was not
needed: the attempt guard already lives in the evidence layer, where attempt
identity actually is, so auto-completion passes the engine a status precondition
instead. The schema is untouched, the frozen contract holds, and a
characterization test fails the moment a record starts carrying an attempt id,
which is when to revisit it.

GodopuandClaude Opus 5 803ba43884 feat(issue-5): auto-completion gate and durable pending notification
The gate does not re-decide anything. Phase 2a already decides, fail-closed and
against contract-pinned vectors; this supplies real evidence to that decision and
commits only if three independent gates agree: the global switch is on, the
backend has observed evidence that it reaches a quiescent state, and the job
itself opted in. Default is off.

The backend allowlist is evidence-based rather than optimistic. Inferring
"finished" from stillness requires stillness to have been observed, and only
three of six backends have that. An operator may narrow the list; a name that
was never observed is dropped rather than trusted, so it cannot be widened by
configuration.

Everything else holds. An unreadable manifest, a report rewritten after
finalization, missing evidence for a declared side effect, a policy that raises:
all refuse. "Could not decide" is never "done". A late explicit terminal wins,
because the boundary refuses the inferred one -- that is the boundary working,
not an error in the gate.

Notification intent is committed in the same atomic write as the state, so a
crash between committing and publishing leaves a record that still says the
world has not been told. Recovery re-sends; duplicates are already dropped by
sequence. A failed send deliberately leaves the intent pending, because an
unsent notification that looks sent is worse than one that is retried.

Two fixes this surfaced. Settling used a request that terminal records refuse,
which made an owed notification impossible to ever settle; settling is now a
status-free bookkeeping request, valid in any state. And the phase 2a guard
against shell references was matching hashlib.sha256 as a substring, so it now
requires a word boundary.

GodopuandClaude Opus 5 cb575fa851 fix(issue-5): address phase 2a round 2 findings (F-C, F-D, R1, R4)
Both reviewers sustained the round 1 fixes and found four more. Each was
reproduced here before being accepted; none were rebutted.

F-C (claude, blocking) -- my own round 1 fix caused this. Making refused writes
exit non-zero also classified an idempotent ACK as a refusal, and the wrapper
finalises an approved job with `status --set completed` on a record that is
already completed. It runs under `set -e`, so the *success* path aborted with
exit 4 before its validation hook and its final stdout line. Reproduced at the
shell. An idempotent result is now distinguishable from a refusal and exits 0; a
genuine conflict still exits 4.

F-D (claude) -- routing the operator write around update_status dropped the
status vocabulary check. Under the rollback flag an invalid status was written
to the record with exit 0, where before it was refused with exit 1 and the record
left alone. The check now runs first, in both modes.

R1 (codex, blocking) -- the previous fix compared identifiers only when they
happened to be present, so evidence carrying none at all was still approved on
the dispatch record's own flags. That is the self-assertion the check exists to
replace. Every identifier must now be supplied and agree, and a report manifest
must associate with the attempt being judged. Identifiers are read from a
collector envelope beside the payload rather than from inside it: a native Herdr
payload may not carry MAM fields, so one appearing there is either fabricated or
a contract violation, and either way it is not evidence.

R4 (codex) -- a sequence number orders nothing unless the compare and the write
are atomic. Two flushes could both read the old value, the newer land first, and
the slower overwrite it. Reproduced deterministically. The mirror now serialises
read-compare-write under a per-job audit lock, taken outside the registry
transaction so a slow mirror still cannot lengthen it, and each write uses its
own temp file instead of a shared name.

All eight new regressions fail against the pre-fix code.

GodopuandClaude Opus 5 56d08efa95 fix(issue-5): address phase 2a cross-review findings (F-A, F-B, R1, R2, R3)
Two reviewers raised five defects. Every one was reproduced here before being
accepted; none were rebutted.

F-A (claude, blocking) -- the CAS table had no row for two transitions the
wrapper legitimately makes, so `submit --type loop|discuss` silently stopped
working by default: the per-iteration re-dispatch was refused and its metadata
discarded, the exhausted-budget finalisation was refused, and the CLI returned 0
both times. Reproduced against the real modules. Fixed by naming those
transitions rather than carving an exception: `redispatch` and `finalize` are
requests gated on operator authority, so the wrapper can move a finished record
while an agent still cannot touch its own terminal. A re-dispatch must advance
the iteration, so a replay cannot resurrect a job. The operator CLI now exits
non-zero with a reason when a write is refused -- the silence is what let this
hide.

F-B (claude) -- moving the audit mirror out of the lock made status.json
last-writer-wins, so a slow flush could leave it behind the registry. It now
carries transition_seq and skips a write that would go backwards, restoring the
sequential consistency the lock used to provide for free.

R1 (codex, blocking) -- the policy called attribution with only the dispatch
record, so it proved the record was well-formed and never confronted the
identifiers the evidence carried. A finalized scenario with a different session,
a different attempt and a manifest from another attempt was still approved.
Observed identifiers are now collected from the timeline and every one must
agree; a manifest belonging to another attempt holds. Collecting every
occurrence rather than the first matters, because taking the first would drop
exactly the contradicting value this is meant to catch.

R2 (codex, blocking) -- a supplied expected_attempt was ignored when the record
had no attempt field, so a compare-and-swap with nothing to compare committed.
It now fails closed, which matters because 2b plans to gate inferred completion
on precisely that precondition.

R3 (codex) -- a status could ride in as an ordinary field, so `progress` could
commit a terminal from inside the boundary that exists to prevent it. Status is
now settable only by the request that owns it, unknown requests are refused, and
pending has an owning request instead of being an untyped merge.

Each of the eleven new regressions was checked against the pre-fix code first.

GodopuandClaude Opus 5 964abc6965 feat(issue-5): shadow watcher that logs would-complete and cannot write
policy.decide is a pure function so the phase-0 scenario fixtures can be fed to
it verbatim. Those seven decisions survived three-reviewer scrutiny, so they are
the contract rather than a fresh set of rules, and the test asserts against
expected_policy.decision directly.

Order inside the policy matters. Transport doubt and staleness invalidate the
evidence itself, so they are answered before anything is inferred from it; a
blocked agent is waiting for a human and can never be completed; attribution
including the execution anchor comes before quiescence, because idle is not
evidence of finishing when a session is reused; and a report must be finalized,
never merely paused, since a debounce is a candidate filter and not an authority.

The shadow runner is never handed the engine, so it has no route to a write.
That is the structural half of P2A-03. The measured half hashes every file under
the registry directory around a full run and asserts it is unchanged, which is a
stronger claim than checking a status field.

Adds the five scenarios P2A-04 requires: a raced double dispatch, a reused
attempt with no anchor, a mid-write report, an unknown status, and a pane
restarted mid-flight. They pass phase 0's own fixture validator, which is what
keeps them honest. The phase-0 test that pinned exactly seven scenarios now
requires the seven to still exist rather than forbidding growth.

Also pins the two phase 1 handoffs as dormant: nothing here spawns a daemon, so
preexec_fn stays unreachable, and nothing calls a frozen shell helper.

GodopuandClaude Opus 5 b49af56c3c feat(issue-5): herdr agent wait watcher with reconnect backoff and a shadow store
watcher wraps one `herdr agent wait` barrier and observes only; it never
concludes. The live contract is encoded rather than described: the timeout
parameter is named timeout_ms because herdr counts milliseconds, --until is
always passed explicitly since omitting it silently drops `working`, and a
non-zero exit is read from stderr because stdout is empty by contract.

A timeout counts as healthy. The socket answered and the state simply did not
change; treating that as a failure would make an idle agent look unreachable.
Only a matched snapshot becomes evidence, so a timeout can never be mistaken for
an observation of agent state.

Backoff doubles from 1s to a 16s ceiling and drops the cached snapshot on
failure. Reasoning from state captured before a gap is exactly what would make a
disconnect look like a completion, which is why the contract answer there is
hold_reconnect.

store keeps dispatch and attribution evidence outside the registry. The job
record carries none of attempt_id, agent_session_uuid or
pane_process_generation, phase 1 froze its schema, and this phase may not write
the registry at all. Keeping the evidence here lets shadow mode carry full
attribution while the registry stays untouched; promoting these fields is a 2b
decision. The execution anchor starts false because acknowledging a dispatch is
not evidence that the attempt ran.

GodopuandClaude Opus 5 2532e78453 feat(issue-5): single CAS transition boundary for every job-status write
engine.transition is now the only writer of job status. It implements the target
table in state-transitions.md §3: claim, non-terminal metadata, explicit
terminals, idempotent re-receipt, refusal of conflicting or late signals with an
audit entry, stale-attempt rejection, and deadline timeout.

Two write paths become one. update_job_status merged fields unconditionally;
pick_pending hand-rolled a correct pending->running swap plus its own audit
mirror. Neither was wrong alone, but a rule added to one silently missed the
other, which is the shape that produced the phase 1 transport bugs. Both keep
their signatures and their preserved legacy bodies behind MAM_ENGINE_CAS=0.

A merged `status` value is routed to the request that owns it, so a raw field
write can no longer slip past the table. Getting that wrong first was caught by
the characterization tests: a metadata merge was overwriting the caller's status
with the pre-merge value.

Lock discipline is now enforced, not described. The lock covers a decision and
one record write; audit mirroring is queued and flushed after release, carrying a
monotonic transition_seq so ordering survives the move. A test watches for
subprocess, socket and sleep calls while the lock is held and asserts none.

Structural correction to my own plan, caught by a phase 1 guard: the plan put the
engine in lib_py/loop, but delegation would then have had to import a sibling,
which is exactly what mixes trees under a frozen loop. The engine belongs with
the registry writers, so it lives in lib_py/delegation and loop consumes it.

GodopuandClaude Opus 5 9389d7ebe2 test(issue-5): phase 2a writer characterization before the CAS boundary
Fixes what the job-status writers do today, so routing them through a single
transition boundary has an oracle instead of a promise. Same ordering that paid
off in phase 1.

X-02 states the claim path's real contract rather than the one the plan first
assumed: pick_pending filters on pending under the lock, so it is already a
correct swap. It duplicates the chokepoint, it does not bypass its safety. The
test pins the properties that must survive routing -- only pending is claimed,
only one session wins, and a session never sees another's work.

Every test is parametrized over MAM_ENGINE_CAS so the legacy body and the engine
body must agree.
