feat(OMN-16773): schedule the delegation chain canary so a dead chain is caught in hours, not weeks - #2955
Conversation
… is caught in hours
The 13-class delegation matrix existed only as a recorded MANUAL recipe.
Nothing ran it. An omnimarket contract change on 2026-08-23 (OMN-15631)
gave node_delegation_routing_reducer a db_io block, the runtime's
_prepare_handler_wiring selected the projection dispatch arm on
db_io.db_tables alone, and every delegation began quarantining. The chain
stayed dead four days until a human fired the recipe by hand while closing
an unrelated ticket (OMN-16767).
delegation-seam-gate.yml was green throughout, correctly: it drives the
seam over InMemoryTransport, where the wiring is constructed by the test.
No in-memory seam test can observe a DEPLOYED wiring arm picking the wrong
path. This closes that gap by firing a real delegation at the real deployed
ingress on a schedule.
- node_chain_canary_effect (EFFECT_GENERIC): POST {probe_url}/skill with
command_name=node_delegate_skill_orchestrator and a per-run correlation
id minted in the handler and NOT settable by the caller; asserts a
terminal inside a declared budget; then scans the quarantine sink tail
for that same correlation id.
- Verdicts are ranked, not collapsed. QUARANTINED outranks TERMINAL_MISSING
because both are true in the OMN-16767 incident and only the first names
the defect. SKIPPED_NOT_CONFIGURED is never reported as CLEAN, and a
configured-but-unrunnable quarantine check fails closed.
- chain-canary.yml: every 2h on omnibase-deploy (the one runner with the
host-gateway alias that can reach the lane's published ports), receipt
into the job summary, non-zero exit on any non-GREEN verdict.
- tests/ci/test_chain_canary_workflow.py is the PR-time guard: the canary
has no pull_request trigger (it publishes a real command onto the lane),
so nothing else would notice its wiring rotting.
Two defects in the quarantine leg were found by running it live rather
than by reasoning about it, and both are recorded at their fix sites:
partitions_for_topic() returns None for a topic the consumer never
subscribed to even when topics() lists it, and aiokafka surfaces
CancelledError out of consumer.stop().
Dev lane only. No claim is made about stability-test, judge, or prod.
…parity fixture Two CI gates caught the same omission from opposite directions. `Handler Contract Compliance` and `imperative-contract-guard` both reported handler_chain_canary as `hybrid`/`undeclared transport KAFKA`: the contract declared only `metadata.transport_type: http` (the /skill ingress POST) while the handler also speaks Kafka for the correlation-scoped quarantine tail scan. Declared on the handler_routing entry rather than via `event_bus.subscribe_topics`, because a declared subscribe topic is how the runtime auto-wires a live consumer and a canary must never become a subscriber on the sink it only samples on demand. node_kafka_replay_compute sets the same precedent: KAFKA declared, event_bus topic lists left empty. `dispatch-parity-gate` reported the committed baseline fixture stale: the corpus grew by exactly this node's contract (137 -> 138). Regenerated with the harness the gate's own error message names. The diff is the +1 contract, the timestamp, and an omnibase-core 0.46.11 -> 0.46.13 pin that dev had already moved independently.
…to dev A concurrent rebase of this branch onto the new dev tip (eb05eee) resolved the tests/fixtures/dispatch_parity/baseline-selection-v2.json conflict by taking dev's side, which silently dropped the regeneration this branch needs: dev's baseline has contracts_discovered=139 and no chain_canary route, while this branch adds one contract. Regenerated with the command the gate's own failure message names: uv run python -m tests.fixtures.dispatch_parity.harness --out <fixture> corpus: 140 contracts, 115 dispatchers, 119 routes, 106 topics, 1042 probes 140 = dev's 139 + this node's contract, which is the whole diff.

Full details: Linked Issues checkExplanation The PR implements the linked issue's live dev-lane validation objective by adding a recurring delegation probe that checks ingress, terminal completion, correlation-scoped quarantine results, and non-GREEN verdicts. The dispatch defect fix itself is not part of this changeset, but the PR explicitly positions the canary as complementary deployed-chain coverage. Full details: Out of Scope Changes checkExplanation The workflow, canary node, models, transport declarations, CLI mapping, CI allowlists, environment-read exclusions, runner metadata, parity fixture, and tests all support the scheduled dev-lane canary objective.

CI Tests Split 1/15 was RED: test_no_env_access_in_node_handlers counted 13
env reads in node handlers against a ratchet of 12, and both new ones were
this canary's ONEX_CHAIN_CANARY_DISABLED kill switch.
Used the mechanism the invariant itself names -- its docstring says 'Known
exceptions are tracked with inline ONEX_EXCLUDE markers' and its failure text
says 'Use ONEX_EXCLUDE marker for exceptions'. This is not a widened
allowlist and not a ratchet bump: the number stays 12.
Two other routes were tried first and rejected on evidence:
* Moving the read to a new node-package module. Refused by check-env-reads
-- it decides new-vs-moved PER FILE ('env-var name is not read in this
file at HEAD'), so a new file is always a new read regardless of where
the code came from. Its approved-path list names handler paths, which is
the repo saying this read belongs in the handler.
* Bumping max_allowed to 13. That ratchet enumerates 12 legacy reads each
with a ticket, under 'New handlers must not introduce os.getenv'. Growing
it is what it exists to prevent.
Three sibling scheduled sweeps already carry exactly this marker for exactly
this shape -- node_dlq_depth_monitor_effect, node_sync_revert_watchdog_effect
and node_evidence_autoclose_sweep_effect -- and all three are on the
check-env-reads approved list at their handler path, as this canary already
is. Following that precedent rather than inventing a fourth arrangement.
The reads are on their own short lines because the scanner matches
ONEX_EXCLUDE per LINE and ruff reflows a long trailing comment onto a
separate one, which silently un-excludes it.
AC6 unchanged: the check is still the first statement in handle(), and it is
still re-read per run so the switch can stop an already-wired runtime.

…— it fails the very path it guards #2955 (OMN-16773) made tests/ci/test_node_migration_shape_reconciliation.py green on node_projection_consumer_flow by adding guarded ADD COLUMNs to 0000 and a new 0001. The gate is satisfied. The failure class is not: every declared-NOT-NULL column was spelled ALTER TABLE ... ADD COLUMN IF NOT EXISTS <col> <type> NOT NULL; and PostgreSQL refuses to add a NOT NULL column to a table that already holds rows unless a DEFAULT is supplied. Against a drifted pre-existing table it raises ERROR: column "topic" of relation "consumer_flow_windows" contains null values and ON_ERROR_STOP=1 kills the migration Job there — the same deploy-stopping failure, at the same point in the deploy cycle, that the OMN-15376 reconciliation exists to prevent. The static gate went GREEN while the class stayed open, which is worse than the original red: the red was visible. Proven by execution on the .201 dev lane (mutable dev lane, throwaway databases, dropped afterwards), not by reading: * seed: omninode_internal.consumer_flow_windows carrying ONLY consumer_group, one row — the exact drift shape the gate's docstring names. * dev's 0000 against that seed: `ERROR: column "topic" ... contains null values`, psql exit 3. * this branch's 0000 -> 0001 -> 0002 against the same seed: rc=0, rc=0, rc=0, converging to 14 and 7 columns with both pre-existing rows preserved. What changes: * 0000 and 0001 — every guarded add becomes nullable, and both gain the BEGIN/END OMN-15376 fence markers they lacked. Without those markers the execution-half suite (tests/integration/migrations/test_node_migration_shape_drift_omn15376.py) cannot derive the pre-fix variant, so this file was silently outside the RED/GREEN proof even after #2955. * 0001's header claim "Keep the applied 0000 bytes frozen" is corrected: the same change edited 0000 in place. * messages_produced gets an explicit ALTER COLUMN ... SET DEFAULT 0, because ADD COLUMN IF NOT EXISTS ... DEFAULT is a no-op on a column that already existed without one. * The declared NOT NULLs are not lost. They are established by the CREATE TABLE in 0000 on the fresh-create path, which is the only path where they can be established without inventing data. This is the node_gateway_link_health_write_effect/0001 precedent exactly. Editing two already-DECLARED migrations is what the OMN-16705 append-only guard stops, and its only sanctioned escape is a new-ordinal supersession landing its successor in the same change. 0002 is that successor and is not a placeholder: it re-expresses the corrected reconciliation additively, so a database that already holds these relations converges from its own ordinal rather than depending on the rewritten bytes of either earlier file. Rewriting 0000 and 0001 is safe because neither was ever applied. Read live 2026-08-28: to_regclass() for both relations is ABSENT on the .201 dev lane, and onex_application_migration_manifest — the relation bootstrap.sql joins to raise 'conflicting migration checksum in canonical node history' — exists on NO .201 lane (dev, stability-test, prod, judge), so the node-migration ledger loop has never run and no content_sha256 is recorded anywhere to conflict with. Both supersession rows carry that evidence. Gates: 226 passed across the shape, checksum-conflict, append-only, manifest declaration and node-discovery suites. The append-only guard is exercised, not bypassed — with the supersession rows removed it FAILS on both files; with them it passes.

… block on infra (#2973) OMN-16876 census item 2. Both checks ran on every omnibase_infra PR and could not block a merge. That is sharper here than in any other repo: `dev` requires exactly ONE status check, "CI Summary" (the OMN-4497 single-umbrella design), so EXPECTED_EXTERNAL_CONTEXTS in scripts/ci/ci_summary_gate.py IS the entire external enforcement surface. A context missing from that tuple has no second surface to fall back on and no branch-protection signal that it is missing. Both entries close a Done ticket that live state contradicts: - OMN-13328 ("receipt-honesty REQUIRED on all repos that produce receipts") -- its OCC contract asserted omnibase_infra, omniclaude and omnimarket "were already flipped". Live readback 2026-08-28: none of the three was enforced on any surface. - OMN-13326 ("contract-validation REQUIRED across all 6 repos") -- genuinely required on omnibase_core, omnibase_compat, omnibase_spi, omniintelligence and omnidash; wired on neither omnibase_infra nor omniclaude. Admission, measured not assumed: - #2955..#2970 (2026-08-28): 16/16 present, 16/16 green for both. - Backfilled BOTH existing merge-time fixtures with real API reads under the fixtures own merge-time filter (started_at <= mergedAt), not synthesised rows: omn15496 (#2546..#2567) and omn15979 (#2705..#2720). The second window independently measured 32/32 present, 32/32 green across both contexts. Three independent windows agree; no freeze-baseline ratchet is indicated. Non-vacuity (OMN-16876 finding 5) -- 16/16 green is also exactly the vacuous pass shape, so each was proven able to FAIL on real input: receipt-honesty gamed receipt (verifier == runner) -> exit 1; real -> 0 contract-validation schema-invalid contract -> exit 1; OMN-10041.yaml -> 0 Both producers declare pull_request AND merge_group and carry no `needs:` and no job-level `if:`, so no upstream failure can skip them; and this layer admits only "success", so a skip fails closed rather than passing.

OMN-16773 — the delegation chain gets a canary
The 13-class delegation matrix existed only as a recorded manual recipe. Nothing ran it.
On 2026-08-23 an omnimarket contract change gave
node_delegation_routing_reduceradb_ioblock; the runtime's_prepare_handler_wiringselects the projection dispatch arm ondb_io.db_tablesalone, so a typed def-B handler began receiving a raw dict and every delegation went to the platform quarantine sink. The chain was dead for four days and was discovered on 2026-08-27 only because a human happened to fire the recipe by hand while closing an unrelated ticket (OMN-16767). The quarantine sink was at ~8,878,924 records at that moment, watched by nothing.delegation-seam-gate.yml(OMN-14771) was green throughout, and correctly so. It drives the delegation seam end-to-end overInMemoryTransport, where the wiring is constructed by the test. No in-memory seam test can observe a deployed wiring arm choosing the wrong dispatch path. That gate proves the seam is right in the tree; this one proves the chain is alive in the lane. Neither substitutes for the other.What lands
node_chain_canary_effect(EFFECT_GENERIC, omnibase_infra) — fires ONE delegation through the recorded recipe (POST {probe_url}/skill,command_name=node_delegate_skill_orchestrator, payload shape fromomnidash/server/routes.ts:216-234, task class fromomnidash/shared/contracts/delegation-task-types.json), asserts a terminal inside a declared budget, then scans the quarantine sink tail for that run's own correlation id.chain-canary.yml— every 2h onomnibase-deploy, receipt into the job summary, non-zero exit on any non-GREEN verdict.tests/ci/test_chain_canary_workflow.py— the PR-time guard. The canary has nopull_requesttrigger (it publishes a real command onto the lane), so nothing else would notice its wiring rotting.Design decisions worth reviewing
QUARANTINEDoutranksTERMINAL_MISSINGbecause in the OMN-16767 incident both are true and only the first names the defect. A canary reporting "timed out" there would have sent someone to look at latency instead of the dispatch seam.SKIPPED_NOT_CONFIGUREDis never reported asCLEAN, and a configured-but-unrunnable quarantine check fails the run. The entire reason this ticket exists is that a check nobody ran looked exactly like a check that passed.ok=truewith no terminal is RED (OMN-16027:publish_envelope()is fail-open, so a cheerful accept proves nothing).probe_urlis required with no default (Rule 8). A canary that guesses its own target can report green about a lane nobody meant to probe.Live evidence — the canary works, and its first result is RED
Run against the
.201dev lane 2026-08-27 (lane serving0.38.11, the pre-fix rev; OMN-16767's fix#2937is still OPEN/BLOCKED):{"verdict": "terminal_missing", "success": false, "detail": "no terminal event inside the 45000 ms budget after 46409 ms: ingress returned ok=false (dispatch_timeout: Local runtime ingress timed out after 45000 ms)", "probe_correlation_id": "da4834a2-7b26-4134-a482-c4f7cdc0388f", "ingress_error_code": "dispatch_timeout", "terminal_event": "", "quarantine_status": "clean", "quarantine_records_scanned": 300}That RED is the deliverable. A red canary on a known-dead chain is the product working.
Correlation-exact broker trace across four probes, posted in full to OMN-16767 — it also shows the failure has moved one hop earlier since the 15:32Z reproduction: all four probes reached
onex.cmd.omnimarket.delegate-skill.v1(offsets 20-23), none reacheddelegation-routing-request.v1, zero terminals, and the quarantine HWM did not advance by a single record (8,878,933 before and after). The orchestrator is no longer consuming its command topic at all. The canary reportedterminal_missing+cleanrather than falsely claimingquarantined— the verdict discrimination is doing real work.Two defects in the quarantine leg were found by running it live rather than by reasoning about it, and both are documented at their fix sites:
partitions_for_topic()returnsNonefor a topic the consumer never subscribed to, even whentopics()lists it — the scan fail-closed on a topic that plainly existed at 8.9M records.aiokafkasurfacesCancelledErrorout ofconsumer.stop(); catching onlyExceptionlet it escape and destroyed an otherwise complete scan result.Scope
Dev lane only (
omnibase-infra, the pre-authorized fully-mutable test platform). No claim is made aboutstability-test,judge, orprod, and the workflow must not be pointed at them without its own ticket — the probe publishes a real delegation command, which is a lane mutation.Two allowlist entries, both with precedent
scripts/check-env-reads.sh— third instance of the documented "RuntimeLocal single-shot compute path has no config-prefetch/overlay seam for a node's own kill switch" case, alongsidenode_evidence_autoclose_sweep_effect(OMN-16106) andnode_sync_revert_watchdog_effect(OMN-16536). The comment flags that three instances of one rationale means the matcher should learn the shape rather than take a fourth path.scripts/ci/infra-node-allowlist.txt— lane and runner topology are infra-exclusive, not a portable omnimarket business-domain capability.Deliberately not in this PR
hook-event-capturegateway entry is currently re-fenced, and OMN-16690's own body states it is un-fenced "only when this ticket is deployed AND the canary shows a row". OMN-16690 is still In Progress. The fence blocks the probe, so it is not built here.Pre-push evidence note (stated, not hidden)
The governed selector escalated to a full suite on
reason=test_infrastructure(this PR adds test files) and refused to run it locally at 1.25x-core load. Its PREFERRED remediation — let GitHub-hosted CI run the full suite on this sha, then re-push — is structurally unavailable for a new branch: noci.ymlrun can exist for a sha that has never been pushed. The.201gate-runner has capacity but its container has nosshclient, so the push cannot originate there. A single-use, sha-bound, receipted override grant was minted and consumed (prepush_override_consumed, contextdegraded-capacity: heavy fail-closed full-suite escalation, nonce6ac205ce211f, head8c150e622cff) so the escalated suite ran here rather than being skipped. It ran green: 24,002 passed / 40 skipped on the escalated pass, plus 8,014 passed / 52 skipped / 1 xfailed on the impacted-subset pass (tests/gates/ tests/nodes/ tests/unit/). No--no-verify, no skip token, no bypass flag. The over-escalation class is already filed as OMN-16745; the new-branch bootstrap gap is a residual worth its own ticket.Ticket: OMN-16773
