F064: the bridge forwarder awaited every conn.send_text in a gather with no
per-connection queue and no send timeout — one slow WS client back-pressured
ALL event delivery to ALL clients (head-of-line blocking on the listen loop).
Each connect_* now registers a _ClientConnection (bounded asyncio.Queue(256) +
sender task); broadcasts enqueue via put_nowait (drop + structlog warn on
QueueFull) and return immediately. The sender drains the queue with each send
wrapped in wait_for(SEND_TIMEOUT=10s). Unregistered legacy sockets (set
directly into a subscription set, bypassing connect_*) get a timeout-bounded
fallback send task held in _pending_sends (ruff RUF006). disconnect cancels +
drops the sender.
F065: route handlers caught only WebSocketDisconnect with no finally — a
non-clean exit (anyio closed-resource, CancelledError, transport error)
propagated without manager.disconnect, leaking the dead socket into every
subscription set forever. Added finally: manager.disconnect(websocket) to all
5 handlers (disconnect is idempotent).
F066: no server-side heartbeat/idle timeout — a half-open socket from a dead
container blocked receive_text forever and was never reaped. receive_text now
wraps in wait_for(IDLE_TIMEOUT_SECONDS=90s); on TimeoutError, log + fall
through to the F065 finally. Named module constants (no config.py precedent for
WS tuning; callers/tests patch them).
TDD: 22 new tests across 3 files (handler cleanup, idle timeout, send queue),
non-flaky across repeats; 1 existing test adapted with a yield for the new
async fan-out (assertion unchanged). ruff/mypy clean, 421 unit/api tests pass.
No type:ignore/noqa.
F068: the do/flow-server circuit breaker only counted rejections whose
`error` field was a STRING in _CIRCUIT_REJECTION_KINDS. A 422 validation
failure (no `error` field, a `detail` list) and a 500/HTTPException
(dict-shaped `error` from the exception handlers) both bypassed the breaker
→ unbounded retries on a storm of either. Added _classify_rejection(payload)
(shared, applied to both servers) mapping all three shapes to a counted kind:
string error (existing), dict error → substring-mapped code
(*DENIED*/*AUTHORIZED*/*FORBIDDEN*/*PERMISSION*→not_authorized,
INVALID_INPUT/*VALIDATION*→incomplete_input, *NOT_FOUND*→None parity, else
→invalid_state), 422 detail→incomplete_input. The dict TypeError defence lives
in the classifier (isinstance, never dict-in-frozenset).
F069: a manifest-registered verb whose HTTP route is missing got FastAPI's raw
`{"detail":"Not Found"}` 404 body — a non-envelope payload the breaker
couldn't classify, so a storm bypassed it. _post now synthesizes an
invalid_state Envelope rejection (with a remediate hint → i_am_blocked/i_am_idle)
for a 404 status, routed through _record_and_check_circuit so the breaker counts
it. A 404 that carries a real Envelope (error field present) is surfaced as-is,
preserving test_flow_post_returns_envelope_on_404. TDD: 422/dict/404 tests in
both server test files; updated test_dict_shaped_error_does_not_crash to assert
the SDK is now called with not_authorized (replacing the pass-through assertion
that encoded the bug).
main_pm's manifest advertises triage (lifecycle.intents_for_role(MAIN_PM)
includes it via _PM_ROLES, alongside triage_all) but flow_main_pm.py had no
POST /triage route, so a main_pm agent calling triage hit a raw 404 that
bypassed the per-verb circuit breaker. Added the route mirroring flow_cell_pm's
/triage — wires to the existing team-scoped choreographer.triage (uses pm.team,
works for any PM role; Main PM gets its own team's blocked/awaiting tasks).
Fix direction: add-route, NOT remove-from-manifest — the manifest is spec-correct
(intents_for_role by construction); removing triage would contradict the spec
and leave main_pm with only cross-team triage_all. TDD: test_triage_route_exists_and_dispatches.
If _configure_git raised CalledProcessError before its `remote set-url`
scrub, .git/config kept the tokenized auth URL (the project PAT) and
_assert_no_pat_leak never ran. The except clauses raised WorkspaceError
without removing the workspace, so the next ensure_workspace's health
short-circuit (valid .git with HEAD + objects) skipped past the leak —
mounting the agent on a workspace whose .git/config let it read+exfiltrate
the PAT. Both clone-failure except clauses now rmtree the workspace before
raising, so a half-configured clone is destroyed and ensure_workspace
re-clones from scratch. TDD: 2 tests (configure-failure leak + timeout).
merge_pr unconditionally set pr_status=merged, pr_merged_at, merged_by,
status=COMPLETED on whatever session it loaded — the only session-terminal
transition in WorkSessionService lacking both the active-status guard
(complete/abandon) and the terminal-idempotency guard (close). Two failure
modes: (1) a retried merge after a successful-but-unconfirmed GitHub merge
overwrote merged_by/pr_merged_at with the retry's actor/timestamp, corrupting
the merge audit trail; (2) merge_pr on an ABANDONED session resurrected it to
COMPLETED, undoing the single-active abandonment. Mirrors close()'s guard:
if status != ACTIVE, return the session unchanged. Both git.py callers await
merge_pr and discard the return, so the no-op is safe. TDD: 3 tests
(happy-path + both modes).
Converts 115 `# type: ignore[...]` suppressions across 23 test files to
no-suppression patterns (helper-return widening to Any, local Any aliases,
cc:Any aliases, cast at narrow call sites, typed fixtures) so the hard
no-type:ignore convention holds across tests/. No test logic or assertions
changed — only mock-wiring mechanics and type annotations.
Gate: ruff check tests/ clean; mypy tests/ (538 files) clean; 176 changed-file
tests pass. Zero real suppressions remain (the 7 grep hits are 3 hygiene-
checker string-literal test inputs and 4 prose mentions in comments).
Convention: no type:ignore/noqa, and pre-existing violations still
violate. The make-quality gate runs 'mypy roboco/ tests/', but the
prior commits' gates only ran mypy on production files, masking 64
type errors across 15 test files (method-assign, unused-ignore,
no-untyped-def, attr-defined, union-attr, has-type, index, misc).
Fixed without any type:ignore:
- method-assign (svc.session.X = / svc.method = AsyncMock()): hold a
local 'session: MagicMock'/'AsyncMock' and assert on it, or stub via
object.__setattr__ / monkeypatch / a typed '_bind' helper returning
Any, or alias 'cc: Any = c' (the pattern the file already used).
- unused 'type: ignore[assignment]' (real code was method-assign):
removed; replaced with the no-suppression patterns above.
- 'Callable[...] has no attribute assert_*': keep a typed local ref to
the AsyncMock and assert on the local, not the method-typed attr.
- no-untyped-def: annotate helper params (Any / pytest.MonkeyPatch).
- attr-defined / index / union-attr: type the helper as Any, narrow
with an 'is not None' assert, or add the missing attr to a fake.
- has-type / return-value: fix the declared return type to the tuple
the function actually returns.
- PLC0415 inline imports: hoisted to top-level.
test_pr_gate_notifies_pm._stub_gate_path converted fully to the
'cc: Any = c' alias (it already used it for one attr) so its five
'# type: ignore[method-assign]' suppressions are gone.
mypy tests/: 64 errors -> 0 (538 files). ruff check tests/: clean.
All 84 tests in the touched files pass.
Convention: no type:ignore/noqa. The F061 in-session audit-emit
tests used '# type: ignore[assignment]' to assign a MagicMock to
AsyncSession.add, and the F060 test assigned to .flush the same way.
Rewritten to hold a local 'session: MagicMock' variable (mypy sees
its auto-children as MagicMock, so .add.side_effect / .flush assign
cleanly with no suppression). Verified via 'mypy tests/' that both
files are now type-clean (the F060/F061 commits had skipped tests/
in mypy, masking two method-assign errors).
_emit_status_transition_audit now writes AuditLogTable rows into
self.session synchronously (session.add) instead of dispatching
AuditService.log_task_event fire-and-forget on its own connection.
The audit row now commits/rolls back atomically with the status
transition in the caller's transaction, closing three facets at once:
- F061: audit commit no longer decoupled from the transition commit
- F073: a committed transition can no longer have NO audit row
(the row rides the same transaction; a swallowed persist can't drop it)
- F075: a transition rolled back inside a verb savepoint no longer
leaves a phantom audit row (the row is in the savepoint too)
log_task_event is now called only from this helper (narrow blast
radius verified); revision_count increment stays at this single
chokepoint. Cycle-time/bottleneck reconstruction from task.<status>
events is no longer silently corruptible.
Tests: test_emit_status_transition_audit_writes_in_session_atomically,
test_finalize_claim_rollback_emits_reversal_audit, escalation-audit
tests retargeted to in-session AuditLogTable rows.
Also: _canonical_bump_files grep-looseness follow-on (F058) -- filter
by subject, not body; git log --grep matches any message line, so a
non-release commit whose body references chore(release): shadowed the
real release commit. Test
test_canonical_bump_files_ignores_body_only_chore_release_match.
The forward task.claimed audit row is flushed before the branch-creation
attempt, and AuditService commits on its own connection, so the rollback's
flush reverts the task row but not that audit row — the journey's last
event stayed task.claimed while the task reverted to its pre-claim status,
diverging from real state and corrupting downstream cycle-time/bottleneck
metrics. The rollback now emits a CLAIMED->original reversal audit row
(only when the forward transition was made) attributed to the claimant.
conftest test-DB defaults matched the project's own running postgres
(roboco/roboco @ localhost:15432, the docker-compose roboco-postgres
service with CREATEDB) instead of the OS user on localhost:5432 which has
no such role — every db_session test failed with InvalidPasswordError
instead of running.
Once the DB connection worked, the self-heal origination DB test went RED
with MAIN_PM_NO_CODE: the self-heal root was task_type=CODE owned by
main_pm, the combo the main_pm_cannot_own_code guard rejects. The Main PM
coordinates the fix (delegates the code work to a cell dev); it has no
code verb. Retyped CODE→PLANNING and rewrote description/AC to
coordination-level.
The module docstring promised self-heal fix tasks 'wait for the CEO's
Approve-&-Start', but _originate created them confirmed_by_human=True and the
orchestrator dispatched them at once — a self-heal fix that re-broke CI would
trigger another cycle, open another auto-dispatched fix, and loop with no CEO
gate on dispatch.
Restore the documented gate:
* _originate opens the task confirmed_by_human=False (held for the CEO).
* The orchestrator holds a self-heal task out of both the PM and dev dispatch
paths until confirmed_by_human flips True.
* approve_and_start (the CEO's start gate) sets confirmed_by_human=True so the
held task finally dispatches (idempotent for board/intake tasks already True).
* list_pending_for_agent scopes the give_me_work hold to self-heal
(source != self_heal OR confirmed_by_human) so an already-alive PM can't grab
it pre-approval — while ordinary delegated subtasks (confirmed_by_human=False
by default, where the delegation IS the authorization) still dispatch.
The 'never self-deploys' guarantee (no merge) is unchanged.
_canonical_bump_files derived the bump set from the previous
chore(release): commit. On the first release there is no such commit,
so it returned [] -> assess set version_bump_plan=[] -> the executor
published a tag with no files bumped (a no-op masquerading as X.Y.Z).
Fall back to the version-reference scan when no prior release commit
exists: the files currently embedding the version are exactly the set a
first release must bump, and the set the first release commit then
records as canonical for subsequent releases. Read-only derivation; the
CEO-approval gate and fail-closed executor are untouched.
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).
