notify() only checked the SENDER role. The recipient was resolved by
NotificationService._resolve_recipients, which drops only unresolvable slugs
— it does not exclude human-only roles. The prompter (intake-1) and secretary
(secretary-1) are seeded agent rows, so they resolved, and an ack-required
ALERT addressed to them sat permanently unacked (no agent auto-acks it),
polluted the panel's pending-ack view, and — via the dedup query's
~acked_by.contains — permanently suppressed any later same-purpose
notification from the same sender to that human role. The knowledge-share
path already excludes all three human-only roles; the general notify path
did not.
Fix: a recipient-role guard in notify() via _reject_disallowed_recipient
(folds the new check into the existing CEO-dependency-block return slot so
notify stays under the PLR0911 return limit). Rejects prompter/secretary
with not_authorized; the CEO is human too but acks via the panel, so it stays
an allowed recipient (its only disallowed case, a dependency-block page, is
preserved). TDD test_notify.py (+3: reject prompter, reject secretary, allow
CEO).
The pr_pass (reviewer) conventions guard reused the dev-path block-finding
remediation: 'add a waiver to .roboco/conventions.yml in your branch'. A
pr_reviewer does not own the assembled cell->root / root->master branch and
has no commit verb on it, so the waiver remediation is unreachable — a false
positive stranded the gate with no self-recovery (the reviewer could neither
commit a waiver nor pr_pass). The fail-open content path is documented
precision-over-recall and stays as-is; the actionable gap is the remediation.
Fix: _conventions_rejection now branches the block-finding remediation on
reviewer=True (mirroring the could_not_run branch from F044). The reviewer
path points at pr_fail carrying the findings as issues so the PR returns to
needs_revision and the DEV fixes the violation or commits the waiver (the dev
CAN commit to the branch); waiver authorship is framed as the dev's action,
not the reviewer's. Dev i_am_done path wording unchanged. TDD
test_conventions_gate_pr_pass.py (+1).
_gate_decision dereferenced the verb-runner result without a None guard.
run_intent returns None when a concurrent transition (cancel or a racing
reviewer) moves the task out of awaiting_pr_review between the precondition
gate and the runner's final composed action (the verb runner's documented
last-action source-status contract). The subsequent t.assigned_to /
t.status / _post_gate_review_to_pr(t, ...) dereferences then crashed the
gate with a 500 AttributeError. Add a None guard that surfaces a clean
invalid_state rejection (re-fetch + re-issue) before any dereference; no
PR post or a2a runs against a None task. TDD test_pr_gate_notifies_pm.py (+2).
The in-verb i_am_blocked(rate_limited) path wrapped RateLimitStateTracker.activate
in a bare contextlib.suppress. A silent activate failure stranded the fleet:
agents were parked in _waiting_records but the provider never entered the tracker,
so the tracker-driven _sweep_rate_limit_probes never probed it and no
_on_probe_success ever resumed them — parked agents stuck in WAITING_LONG.
Fix: (1) replace the bare suppress with a try/except that logs an error event
naming the provider + affected agents; (2) in _sweep_rate_limit_probes, after
probing the tracker-listed set, scan _waiting_records for any rate_limit_lifted
provider the loop did NOT cover and probe it via the time-expiry fallback (empty
state -> probe now) so _on_probe_success resumes the parked agents. The fallback
reads only local memory, so it still resumes when Redis was down at park time
(list_rate_limited_providers failure now falls through to the orphan scan instead
of returning early).
The pr_pass gate runs the toolchain + conventions guards on the REVIEWER's
workspace, but their remediation text said 'call i_am_blocked' — a verb the
PR reviewer does not have. The reviewer would chase a verb they cannot call
instead of rejecting the PR.
Make the guards reviewer-aware: a reviewer=True flag (passed by _pr_pass_blocked)
switches the remediation to pr_fail(issues=[...]) — the reviewer's reject
lever, sending the PR back to needs_revision for the dev to fix the
environment / validator. The dev (i_am_done) path keeps i_am_blocked, which a
dev does have. _conventions_guard (the pr_pass path) now passes reviewer=True
through to _conventions_rejection.
escalate_up had composes=() and no source-status guard, so a PM could
escalate a COMPLETED/CANCELLED task and apply_escalation set it back to
BLOCKED — bypassing the state machine's terminal-state invariant.
Defense in depth:
- spec: add PRECONDITION_NON_TERMINAL to escalate_up's extra_preconditions so
the lifecycle gate rejects terminal tasks (invalid_state) before the
journal:decision write fires; generalize _check_intent_preconditions to
honor non-tracing rejection_kind (not_authorized / invalid_state).
- service: apply_escalation (the single write primitive) returns False and
refuses to mutate a terminal task — covers the HTTP escalate route which
bypasses the spec gate. escalate() / escalate_up_to_role() return None on
refusal so the gateway emits a clean invalid_state envelope.
- route: the HTTP escalate route 409s a terminal task BEFORE sending the
escalation notification (so a finished task isn't yanked back, PM not pinged).
Two task creates for the same project/HEAD can race to populate the
conventions cache; the loser's INSERT fails the partial-unique index with
IntegrityError. A bare session.add + flush poisons the shared session (the
task-create transaction rides the same session), so every subsequent op
raises 'this session is in error state' and task creation crashes.
Run the INSERT in a savepoint (begin_nested) and swallow the IntegrityError:
only the savepoint rolls back, the outer transaction stays usable, and the
winner's row satisfies the next _cache_get.
A one-shot grok container whose entrypoint ran grok_auth --check and found
the token missing/expired exits 78 (EX_CONFIG). Crash-retrying 3x burns
tokens for zero progress — the agent cannot start without a valid token.
Park the provider with kind=auth_missing (same shape as the 429 exit-75
path) so the probe-resume loop revives the task once grok_auth.refresh_if_stale
mints a fresh token; if still expired, the next exit 78 re-parks (no burn).
Also fixes a latent F035 regression: _park_provider_unavailable now registers
a WaitingRecord, so the bare-__new__ rate-limit park test had to set
_waiting_records + stub _persist_waiting_record (mirrors the overload-test
fixture).
_enforce_grok_cost_budget killed + evicted the container without calling
_finalize_spawn_session, so the open agent_spawn_sessions row stayed open
(ended_at IS NULL) and the burned usage/cost was never recorded in the
dashboard.
Call _finalize_spawn_session(exit_reason='cost_cap') BEFORE popping the
instance — it reads self._instances[agent_id] for the model +
usage_session_id, which the pop would lose.
The prior self-PATCH 401 fix only carried X-Agent-ID/X-Agent-Role. Arming
ROBOCO_AGENT_AUTH_REQUIRED=true made the middleware require a signed
X-Agent-Token, so every orchestrator self-call (auto-block / auto-resume /
auto-recover / SLA annotation) 401'd and silently no-op'd — wedging
paused/blocked parents.
Add _system_api_headers() that wraps the base headers with a signed token
for the system identity (issue_agent_token); switch all six self-call sites.
Dev fallback: no secret set => UNSIGNED sentinel + auth not required.
The bare 'error 529'/'error 500'/'error 503' markers were broad enough to
false-match an agent that merely writes about an HTTP status code in its own
notes ('the endpoint returned error 500, retrying'), parking the whole
Anthropic fleet on a non-issue.
The SDK error formatter emits 'API Error: NNN' + a JSON error type, so the
remaining 'api error: 529/500/503' + 'overloaded_error' +
'internal_server_error' markers cover every real overload without that
false-match surface.
The SDK server writes model-API errors (529/500/503) to /tmp/sdk-server.log,
not stdout, so an overload marker can appear only in the durable Claude
transcript — the same rationale already applied to the session-limit
detector. _provider_overload_park_target read only docker logs, so an
overload was missed and the agent crash-respawned straight back into it.
Now concatenates the transcript tail before matching, mirroring the
rate-limit path.
_park_provider_unavailable parked the provider + offlined the instance but
never registered a WaitingRecord, so _on_probe_success -> _parked_agents_for
(always filtered on waiting_for=='rate_limit_lifted') returned [] and
resolve_wait revived nobody — recovery fell to the 600s stale-claim reaper
instead of the probe-success path the parking design relied on.
Register + persist a rate_limit_lifted WaitingRecord at park time (mirrors
mark_waiting_long, minus stop_agent — the container is already dead).
Companion reaper guard: _reap_with_service now skips provider-parked
assignees (_assignee_is_provider_parked) so the claim survives until the
probe revives the agent — otherwise the reaper releases the claim to pending
and probe-success respawns on a task the agent no longer owns.
_pm_made_rule_following_retry bounds its tracing_gap audit lookup with
since = record.get('last_check'). A stale persisted last_check from before
the restart matched pre-restart tracing_gap rows, falsely resetting the
breaker on the very first post-restart spawn — exactly when a fresh strike
count should be evaluating current state.
_partition_respawn_rows now re-stamps last_check to the restore time on
every restorable entry, bounding the lookup to post-restart gaps only.
_readopt_running_agents registered re-adopted ACTIVE instances with
container_id=None. _check_health skips container_id-is-None instances, so
when a re-adopted container later exited the stopped-container handler
never ran and the task stranded under a phantom ACTIVE instance forever.
Add _resolve_container_id (docker inspect -f '{{.Id}}') and store the real
id on re-adopt. Best-effort: a probe failure degrades to None (still
ACTIVE; the reaper's Docker-liveness fallback covers it).
F031's role_for_slug_or_none fix made the unknown-assignee release branch
in _dispatch_claimed_without_agent reachable (the human-only guard no
longer raises/short-circuits on a stale slug). Lock that reachability in:
a claimed task with an unknown-assignee UUID past grace returns the slug
(not None) so get_agent_role -> 'unknown' releases the claim to pending
for a role-matched reclaim.
The purpose-based dedup suppressed a same-purpose (same sender/type/task,
overlapping recipients) notification while a prior one was unacked. For
informational types (KNOWLEDGE_SHARE / MENTION / A2A_REQUEST / BROADCAST +
the pickup-proves-receipt triad) each send carries DISTINCT content (a new
learning, a new mention) and acking is voluntary, so a recipient who never
acks the prior one let the dedup permanently suppress every subsequent
same-sender broadcast - silent learning-broadcast data loss.
The dedup's anti-loop rationale (stop unacked-set inflation soft-blocking
i_am_idle) only holds for action-required signals. Gate the dedup on
ACK_REQUIRED_BY_TYPE.get(type, True): action-required types still dedup,
informational types always create. Unmapped types default True (dedup on).
TDD red->green; ruff + mypy clean; notification + dedup suites green (20).
NotificationService._create_notification built NotificationTable without
requires_ack, so the column default (True) applied to EVERY notification -
including informational REVIEW_REQUEST / DOCUMENTATION_REQUEST /
A2A_REQUEST / KNOWLEDGE_SHARE (ACK_REQUIRED_BY_TYPE -> False) and every
@mention from MessagingService._notify_mentions. Each false ack-required
inflated the recipient's unacked set and soft-blocked i_am_idle into
respawn churn.
- _create_notification: requires_ack=ACK_REQUIRED_BY_TYPE.get(type, True)
(unmapped types default True - preserve the action-required bias).
- _notify_mentions: requires_ack=False explicit (MENTION is informational).
TDD red->green (identity is False/is True assertions - the mocked
flush doesn't apply SQLA's insert-time default, so pre-fix the attribute
was None); ruff + mypy clean; notification suite green (18 passed).
The pr_fail a2a steer to the owning PM is fire-and-forget; a PM respawned
into needs_revision later read none of it (build_task_handoff never looked
at notes_structured), saw a generic 'needs revision' with zero concrete
change-requests, and re-submitted the same PR (the 2026-06-27 infinite
pr_fail loop on 9980d0a0 / PR #138). The signal-gap was only partially
closed by the a2a.
build_task_handoff now extracts notes_structured.pr_review
(verdict/summary/issues/head_sha — the slot pr_fail authors on every fail)
into a pr_review field on the handoff, so every PM briefing for the task
carries the concrete change-requests. A prior pr_fail alone now counts as
prior-work-worth-resuming. Type-guarded + capped; absent => no key (no
misleading empty slot).
TDD red->green; ruff + mypy clean; evidence_builder suite green (14 passed).
The root loop-stopper (F016) was root-only; a weak cell PM could re-submit
the unchanged cell->root PR after a pr_fail and loop awaiting_pr_review ->
pr_fail forever (the cell analogue of the 2026-06-27 root loop).
pr_fail stamps the assembled PR's head SHA into notes_structured.pr_review
.head_sha for cell AND root gate tasks alike (the capture is gate-verb-
level, not root-level), so the same structural refusal applies to submit_up:
if the cell PR's current head SHA equals the SHA the last pr_fail recorded,
no new dev work landed on the cell branch -> the diff is byte-identical ->
refuse, do not re-open the gate. Different SHA -> branch advanced -> allow.
- _submit_up_unchanged_pr_guard mirrors _submit_root_unchanged_pr_guard
(cell-PM remediation: re-delegate to the dev + wait for re-assembly),
wired into submit_up after _submit_up_guard passes.
- Renamed shared _current_root_pr_head_sha -> _current_pr_head_sha (both
guards use it; the lookup was never root-specific).
- Every ambiguous case FAILS OPEN (no prior fail, no recorded sha, no
pr_number, no resolvable project, git/closed-PR None) — only the exact-
unchanged case is hard-blocked.
TDD red->green; ruff + mypy clean; F007+F016 guard suites green (15 passed).
Both verbs compose a single atomic action whose None return (the verb's
own result) flowed out of run_intent and was dereferenced as t.status,
HTTP 500-ing with no actionable rejection:
- F016 submit_root: submit_for_review returns None when the root->master
PR was already opened / the task raced out of in_progress. Post-runner
None-guard extracted into _submit_root_finalize -> invalid_state
(re-fetch; if awaiting_pr_review the PR is open, wait for reviewer;
else re-delegate fixes and retry) instead of None.status.
- F017 i_am_blocked: escalate returns None in four cases (no task, no
agent, no resolvable escalation-target slug, no target agent row) e.g.
a developer whose role has no PM above it. _run_i_am_blocked_intent
now guards updated is None -> (t, invalid_state rejection) with
remediation (re-fetch + escalate to CEO directly / retry) instead of
the caller deref'ing None.status -> 500 + respawn-loop.
TDD red->green; ruff + mypy clean; gateway suite green (58 passed).
F005: the single-file bind mount of auth.json pinned the inode, so the
orchestrator's atomic refresh (tmp+rename within ~/.grok) never reached a
running grok container — a long-lived container hung at the login prompt
when the original ~6h token expired. Mount the host ~/.grok DIRECTORY (ro)
at /home/agent/.grok-auth-ro; the entrypoint symlinks ~/.grok/auth.json at
that RO mount so grok + the --check backstop read the live credential (the
directory mount sees the host-side rename) while grok's writable state
(config.toml, sessions/) stays in the image's ~/.grok.
F006: a rotated refresh_token is single-use — xAI invalidates the old one
the instant it issues the new one. If the atomic write failed after the
rotation, the file kept the now-dead old refresh_token and the credential
was permanently lost on the next refresh. _atomic_write now falls back to a
direct write when tmp+replace fails, so the rotated token always lands on
disk (losing the write is catastrophic; losing atomicity is not).
TDD: RED tests watched fail, then GREEN. ruff+mypy clean; 32 grok tests
green, no regressions.
F003/F014: /api/v1/do/* only required X-Agent-ID (UUID) — no token check,
unlike the flow routers' role guards. A forged X-Agent-ID passed. Added
require_any_authenticated_agent (token-only; do router serves all roles)
and applied it as a router-level dependency. Binds X-Agent-ID to a verified
HMAC token when ROBOCO_AGENT_AUTH_REQUIRED=true; rejects a forged token
even in dev mode.
F004: /ws/* per-agent streams (channels/agents/sessions/notifications)
never read the nginx-injected X-Agent-Token, so in strict mode an agent on
the Docker network could subscribe to another agent's notifications with
no auth. Added _require_panel_token verifying the CEO panel token against
the CEO identity; wired into all four per-agent streams (system stream
stays operator-only per its docstring). Same strict/dev contract.
TDD: RED tests watched fail (no gate -> 200/accept), then GREEN. ruff+mypy

_activate_batch_root_subtasks flipped a held root-subtask to team=MAIN_PM
but left task_type=code (intake only coerces main_pm-team drafts, so a
board-routed code root reached activation still code-typed). The
main_pm+code combo re-introduces the 2026-06-27 meltdown. Mirror
approve_and_start's own retype via main_pm_cannot_own_code so the
activated child is a planning-typed coordination root.
TDD: RED test_activate_batch_root_subtasks_retypes_code_to_planning

Defense-in-depth for the spawn_agent human-role chokepoint (d31d6719).
The chokepoint structurally guarantees no CEO/prompter/secretary container
can ever spawn — every dispatcher goes through spawn_agent. But two
dispatchers resolve an arbitrary assigned_to and spawn it with only a
None/unknown-role filter, so a human-assigned task would reach the
chokepoint and RAISE: caught by the per-dispatcher try/except, but it
aborts that dispatcher's whole tick (stalling other respawns behind the
mis-assigned task) and error-logs every cycle. The other dispatchers are
already safe by whitelist/hardcoded slug (blocker_resolver_slug returns
None for non-PM/non-BOARD; escalation/approval use whitelists; marketing
and audit hardcode their non-human slug).
- _claimed_task_needs_agent: return None for a CEO/prompter/secretary
assignee — no container to respawn, and do NOT release a human-owned
task to pending (that would re-route it to a PM). Leave it for the human.
- _dispatch_pm_review_work (assigned branch): skip a human-only assignee
so a CEO-assigned awaiting_pm_review task neither spawns nor aborts the
dispatcher's tick.
Audited all target-iterating dispatchers; only these two lacked a filter.
Regression tests cover both skips.
A live 2026-06-27 incident saw a CEO agent container spawned. Root cause:
_dispatch_a2a_work iterates every A2A/notification target and spawns it
with no human-role filter, and _is_agent_active('ceo') is always false
(the CEO is never a container), so the 'skip if active' check could never
protect the CEO. Any CEO-addressed notification (board handoff, escalation)
launched a CEO container — the system acting as the human CEO: a trust
violation. The CEO is the human operator; intake (prompter) and secretary
are human-driven chats launched through their own dedicated guarded paths
(_spawn_intake_container / _spawn_secretary_container), never spawn_agent.
Fix: a single chokepoint guard at the top of spawn_agent refuses
Role.CEO / PROMPTER / SECRETARY (raises AgentReadinessError + logs). This
structurally covers every dispatcher present and future, since they all go
through spawn_agent. Plus a defense-in-depth skip in _dispatch_a2a_work so
a human-role target never even calls in (avoids error-log spam; the
notification stays for the human to read in the panel).
Safe: the dedicated human-spawn paths do not route through spawn_agent.
Regression tests: spawn_agent refuses ceo/intake-1/secretary-1, does NOT
refuse a real agent; _dispatch_a2a_work skips CEO/intake/secretary targets
and still spawns real-agent + mixed-target cases.
A sibling's PR merging into the parent branch while a dev worked leaves the
dev's branch behind its base — the assembled PR then can't merge cleanly and
the sibling's changes go missing (the 2026-06-27 out-of-order dev-task break).
The behind-base gate refuses i_am_done in that state and steers the dev to
sync_branch (the Phase B1 gate-level rebase verb).
- GitService.is_behind_base: rev-list --left-right --count across
origin/{base}...origin/{head} → (behind, ahead); fetch-first so origin
reflects the pushed head. Raises on git failure (consistent with
rebase_onto_base); malformed stdout degrades to (0,0).
- Choreographer._behind_base_gate: wired into _i_am_done_gate after
_ensure_branch_pushed. behind>0 → invalid_state remediate→sync_branch.
Fail-open on git/base-resolution error (flaky fetch can't strand a task at
the submit gate — the merge layer has its own behind checks). Skipped for
branchless roots and protected bases (master/main/-prefixed).
Tests: gate (6: refuse+steer/up-to-date/branchless/protected/fail-open-base/
fail-open-git), is_behind_base (6: parse/up-to-date/malformed/argv-form/
requires-branch/missing-project). ruff + mypy roboco/ tests/ clean; unit green.
Raw shell git is denied to agents (Bash(git:*) base deny), so a developer
whose branch fell behind its base had no gate-level rebase — only the
CEO/PM-only /rebase HTTP route. sync_branch is the dev verb that wraps the
rebase through the gate (traced + evidenced), so the 'everything goes through
the gates' invariant holds.
- lifecycle: IntentSpec sync_branch (dev-only, ownership-gated, composes=(),
git-only — no DB transition); _next_hint_synced helper.
- GitService.sync_task_branch: rebase task.branch_name onto its resolved base
via rebase_onto_base (fetch + rebase + force-with-lease push).
- Choreographer.sync_branch + _sync_branch_preflight_rejection: not_found /
unknown-role / spec-gate / no-branch / protected-base guards, then the git
op; conflicts abort (no force-push) and steer to resolve-by-hand; git failure
steers to i_am_blocked.
- HTTP route /api/v1/flow/developer/sync_branch + SyncBranchRequest schema.
- MCP tool sync_branch(task_id) + _TOOLS registration (manifest auto-propagates
via intents_for_role(Role.DEVELOPER)).

Kind 2 (cell-task wave chain): a new cell-task under root-subtask UT_n
depends on every cell-task under every root-subtask in UT_n.dependency_ids
(the kind-1 wave-chain edges), so its branch carries the previous wave's
merged cell work. Re-derived from the root-subtask's deps, not the cell-task's
own dependency_ids (which also carry UX/product-fanout edges the by-osmosis
edge must not pick up). A root may fan to several cell-tasks (different cells),
so the previous wave's cell-task is a SET.
Kind 4 (by-osmosis): the first dev task (sequence 0) under a cell-task depends
on each predecessor cell-task's tail (max-sequence) dev task, so the new wave's
first branch carries the previous wave's fully-merged tail. Subsequent dev
tasks inherit the tail via kind 3 or the merged base.
Both wired from _create_subtask_from_inputs, dispatched on parent.team
(MAIN_PM -> kind 2; cell team -> kind 4). Pure helpers
(cell_task_wave_chain_depends_on, by_osmosis_tail_dev_tasks) unit-tested in
test_sequencing.py; TaskService methods integration-tested. Idempotent +
best-effort throughout (add_dependency dedupes; missing predecessors are
no-ops). Also fixes a latent mypy-tests gap (estimated_complexity required on
direct TaskCreateRequest calls in the S2 tests).
Pure dev_task_collision_edges in sequencing.py turns a parent's surfaced
siblings into (depends_on_id, task_id) pairs via SequencingService. TaskService.
wire_sibling_collision_dag wires them through add_dependency (idempotent). The
choreographer calls it after each dev-task delegate so the sibling collision DAG
is built incrementally as the cell PM decomposes — file-overlap serializes,
migration chains, shared-last; stable (priority, sequence) ordering keeps edges
from flipping into reverse cycles on re-runs.
The cell/main PM's delegate verb now carries the dev-task collision
surface (intends_to_touch / adds_migration / touches_shared) and an
explicit depends_on override through DelegateRequest -> DelegateInputs
-> _create_subtask_from_inputs -> create_subtask, and create_subtask
forwards sequence / dependency_ids / batch_id / surfaces into the
prepared TaskCreateRequest instead of dropping them (the base create
already persists them at task.py:878-884).
This is the plumbing for the multi-level sequencing model edge kind 3
(dev-task collision DAG). Previously a dev task delegated with a
collision surface or an explicit dependency lost it before persistence
— dependency_ids was always [], so the only dev-task ordering was the
weak assignee-keyed spawn barrier (the live 2026-06-27 out-of-order
break: 40842957 started before 9b3682b8's PR merged). Phase S2 runs
SequencingService over the surfaced siblings and wires the DAG via
add_dependency.
A dev task in needs_revision must go back to the developer, never the
pool. The pool path let a cell PM re-claim the revision (PMs can claim
needs_revision) — the live 2026-06-27 'needs revision on a dev task sent to
the cell PM' bug.
fail_qa's original_developer marker is the fast path, but it is
unreliable in practice (live observation: never persisted), so the
unassign else-branch was the load-bearing path and it dropped the task
into the pool. Add a work-session fallback (_resolve_revision_dev) that
resolves the developer who actually worked the task — the most recent
work session whose agent is a developer, the QA's own session excluded
— and reassigns to that dev instead of unassigning. Only unassign when
no developer ever touched the task. Self-heals the marker so a
subsequent re-fail takes the fast path and the QA-review index
attributes the work correctly.
The branch tip had 15 mypy tests/ errors in files this bundle did not author,
which blocked CI's make quality mypy step (mypy roboco/ tests/) regardless of
the bundle's own commits. Pre-existing is still existing — fix every one:
- test_schemas_v1_flow.py (8): the StrList coercion tests intentionally pass
SDK-nested list-of-strings input ([[['...']]], {'item':{'$text':'...'}}, int,
dict). Annotate those literals as list[Any] locals so mypy accepts the
coerce-able shape; the StrList BeforeValidator still flattens to list[str] at
runtime. No type:ignore.
- test_pr_gate_records_verdict.py (3): notes_structured is dict|None; narrow
with 'assert t.notes_structured is not None' before indexing (the existing
pattern at line 90).
- test_pr_review_hand_format_guard.py (1 site, 2 errors): the _verb_runner()
spy assertion — use the cc: Any = c alias idiom so assert_not_awaited
resolves; drops the now-unused type:ignore[union-attr].
- test_pr_gate_notifies_pm.py (1): drop the unused type:ignore[method-assign]
on the a2a.send reassignment.
- test_content_models.py (1): narrow coerced with isinstance(coerced,
PrReviewContent) before reading .issues (the base _Content lacks the field).

The 2026-06-27 infinite pr_fail loop: a Main-PM root (PR #139) was pr_fail'd,
routed to needs_revision, and re-submitted byte-identical → awaiting_pr_review
→ pr_fail again, forever. The prior hint/a2a steer was ignored by the weak
coordinator model — hints don't stop a model that won't read them. A HARD gate
refuses the re-submit when the assembled root PR's head SHA is unchanged since
the last pr_fail (no new cell work → identical diff); a different SHA ⇒ the
branch advanced ⇒ allow. Every ambiguous case fails open (no prior fail, no
recorded SHA, no pr_number, unresolvable slug, git error, closed PR) — only the
exact-unchanged case is hard-blocked.
- content/models: PrReviewContent.head_sha (optional; JSON col → no migration).
- git: get_pr_head_sha (GitHub pulls API; None on any failure → fail-open).
- pr_gate: pr_fail captures head_sha into the verdict record; pr_pass does not.
- _impl: submit_root runs _submit_root_unchanged_pr_guard after _submit_up_guard;
_current_root_pr_head_sha resolves slug + current SHA (fail-open).
- pr_review: extract module-level resolve_task_project_slug, shared by the mixin
and the gate helper (_LegacyChoreographer reaches it via cast to the
ChoreographerHelpers typed view — it doesn't inherit the helpers mixin).
- tests: test_submit_root_unchanged_pr_guard (11 — refuse/allow/6 fail-open/3
capture-side, mypy-clean via cc:Any spy idiom, zero type:ignore) +
test_pr_gate_notifies_pm capture-path stub.
