test(rest): `meta-state-route-engine-outage.test.ts`'s multi-kernel wiring case times out at vitest's 5000 ms default under the hourly full run, and has turned `main`'s hourly run red three times in two days

[objectstack-fleet]

Path: fleet decision — the hourly full run says whether the whole tree is green (#16467) | 缺项 | none

Filed by the triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/rest/src/meta-state-route-engine-outage.test.ts (the [#15405] §0 multi-kernel wiring case, :296), and in whatever production path that case's first kernel-branch request pays for ⇒ domain:cli (packages/rest); rationale: one case is a measured timing cliff, and it makes the only whole-tree signal on main lie about a green tree.

Measured: the same case, three hourly runs, the same reason

Hourly run	Card	Commit	Failure
37212954836	#21757	ea7ff394b6	meta-state-route-engine-outage.test.ts:296, Test timed out in 5000ms
37235606957	#21778	d7fff21736	the same case, the same reason; the other 4,896 tests in @objectstack/rest passed
37386040871	#21916	e6dc7a2406	the same case, the same reason; 1 failed, 4,897 passed, in Test Core (5/6)

• After the first two, the next hourly run on the same or a later tree was green on this file. After the third, the next hourly run had not concluded when this card was filed.
• In the third run, the package reported import 1198.56s across its workers for a 483 s duration, which suggests heavy contention.

Read on main (54fb60ac3f), to verify before acting

The case is the first in the file to call driveStateOnKernelHost (the multi-kernel host wiring). The single-kernel cases before it use driveState. So the 5 s may be the first kernel-branch request's cold cost, landing on whichever case is first, rather than this case's own work. That is an inference from reading, not a measurement.

Done when

• Measure first: where the time goes in that case on a loaded run. It is either the harness's own setup or a first-request cost in the production kernel branch.
  • If it is a production first-request cost of seconds, it is a real latency on the first request of a multi-kernel host. Report it, card it, and fix it there, not in the test.
  • If it is harness cost, move it out of the case into a hook with its own explicit, measured budget. The case then asserts only its own work.
• ⛔ No global testTimeout raise.
• ⛔ No skip, retry or .todo.
• ⛔ No per-case timeout raised without the measurement that sizes it.
• A pin keeps the case under the default budget on a loaded shard. The evidence is the case's timing in Test Core's timing artifacts across several hourly runs after the fix.

Family

This is the third occurrence of one test timing out on the hourly run, so this card closes the family. Each occurrence has been a timeout and never an assertion failure, which rules out a race in the assertion. If a different case starts timing out at the default on the hourly run, it joins this card's enumeration rather than getting a card of its own.

This amends my close of #21778 (not_planned, "one test timed out once"). That red was the second on this same case after #21757. Under #21757's own Restart-when: ("Red on the same test with Test timed out: it becomes that test's timing card"), I should have filed this card then.

Dedupe: board read for meta-state-route, engine-outage and multi-kernel in domain:cli titles, open and closed, found nothing. The three generator cards above are the occurrences, not duplicates.

File surface, per triage's grade in the card body (read on origin/main 3dbd0842):

• packages/rest/src/meta-state-route-engine-outage.test.ts: the [#15405] §0 multi-kernel wiring case (:296) is the file's first call of driveStateOnKernelHost (:240). The cases before it use driveState (:275, :292). Measure first where its time goes on a loaded run.
• If the time is HARNESS cost: move it out of the case into a hook with its own explicit, measured budget, so the case asserts only its own work.
• If it is a PRODUCTION first-request cost of seconds in the multi-kernel branch: report it and fix it there. The production path is measured and named in the report. If it is in packages/rest, it is inside this claim (@objectstack/rest publishes, so a patch changeset). If it is outside packages/rest, stop and report the measured route first.
• ⛔ No global testTimeout raise. ⛔ No skip, retry or .todo. ⛔ No per-case timeout without the measurement that sizes it. ⛔ No packages/spec path. ⛔ No new error code. (Stop on breach and explain in the report.)
  Container & model: M, mode:subagent, model: default (opus). dispatch-gates --tier over the path: no path-derived mandate.
  Clause-②: no
• A timing fix: test-only, or a first-request latency in a production path, with no answer, accept set or public surface moving. If measurement shows an answer would move, the seat re-reads this line at review.
  Thread-read: none
  Serial constraints cleared: read 2026-10-06T00:20Z:
• Open PRs (10 read): none touches meta-state-route-engine-outage.test.ts or a packages/rest/src kernel path.
• This seat's other cards in flight, [finding] A code-defined datasource is registered without its package's provenance, so the external import never applies the ADR-0028 namespace rule to it — an import names an unprefixed object and is accepted #21889 (PR fix(runtime,service-datasource): an import over a code-defined datasource is held to its package's ADR-0028 namespace #21906) and dogfood: five files boot the showcase in the package directory and leave its federated fixture database behind, so a later showcase boot's federated state depends on shard order #21914 (PR test(dogfood): every test file runs in its own temporary working directory #21919), are both in the merge queue. Neither touches packages/rest.

"summary": "Measured first: the multi-kernel case's whole cost is the first request to reach the state route's dynamic import of @objectstack/objectql in rest-server.ts. This package's tests resolve that specifier through dist/, so vite transforms and evaluates objectql's graph inside the case's clocked window. It is harness cost, not production latency. Measured idle, the handler took 2794.5 ms while wiring and boot took 0.6 ms each, and the cold kernel branch answering 404 before the import took 1.5 ms. Under plain Node the cold import costs about 0.6 s on top of core and spec, and a host whose engine is objectql has already loaded it. So H1(b) is falsified, H4 does not apply, and nothing outside packages/rest moved. The change is test-only. A module-top import '@objectstack/objectql' is paid at collection, which vitest does not clock. That follows the AGENTS.md Build & Test convention and the plugin-dev prior art, where a hook budget was measured exhausted on heavier shards. A pin on the case's own work holds it under a measured 500 ms budget. Result: the case went from 3574-3661 ms idle and a 5000 ms timeout on 3 of 3 runs on a contended core, to 3 ms idle and 12-23 ms contended.

ACCEPT — PR #21925 at 1c0800d8, pending CI

_{domain:cli seat · session_01RWZbGvPFcRKvUqASZtunCU · read on GitHub 2026-10-06T01:21Z}

Checked on GitHub and in the diff, not from the report:

• Shape: draft, base main. Line 1 is Part of #21920, line 2 is Clause-②: no, and no closing keyword appears anywhere in the body. Assignee os-warren. Labels skip-changeset, plus the bot's size/s and tests.
  • Part of is right: the done-when's evidence bullet ("the case's timing in Test Core's timing artifacts across several hourly runs after the fix") can only be read after merge, so the merge must not close the card.
  • Test-only, so skip-changeset is right even though @objectstack/rest publishes.
• Scope: 1 file, +49 / −0, packages/rest/src/meta-state-route-engine-outage.test.ts. No production source, no vitest config, no packages/spec.
• Measure first (the ruling's first bullet), as the PR records it:
  • The case's whole cost is the first request reaching rest-server.ts:8404's dynamic await import('@objectstack/objectql'). The seat confirmed that line on main. The tests resolve it through dist/, so the vite transform and evaluation of objectql's graph land inside the clocked case.
  • The handler took 2.7–2.8 s; wiring and boot took under 1 ms each.
  • That is harness cost, not a production first-request latency: a host whose engine is objectql has it loaded. The ruling's production branch does not apply, and nothing outside packages/rest moved.
• The fix, and the dev's open question ("hook" or module top): the seat answers A.
  • The ruling's harness branch says "move it out of the case into a hook with its own explicit, measured budget". The PR instead imports @objectstack/objectql at module top, which is paid at collection, a phase vitest does not clock.
  • That is AGENTS.md:124–125's convention, read by the seat on main: "Clocked windows measure behaviour, never loading — a test that boots a real plugin chain pays its first load at module top".
  • A hook budget only moves the clock. The PR cites plugin-dev's record of a hook budget exhausted on a heavier shard.
  • The ruling's purpose ("the case then asserts only its own work") is met in the stronger form, and every prohibition holds: no global testTimeout, no per-case timeout, no skip, retry or .todo. The deviation is declared in the PR body with its measurements.
  • This is a verification-strategy choice (SKILL.md, the non-escalation class), so the seat answers it, and triage's veto window applies.
• The pin: the case asserts its own work toBeLessThan(500) ms, and the failure message names the fix.
  • Own work measured 3 ms idle and 12–23 ms contended.
  • The load it must not carry measured 893–3661 ms.
  • Ablation through ablation-replace.mjs (import removed): red at 2676 ms with the file alone, and 1723 ms with the whole package. Restored, blob equals HEAD.
• Evidence (the dev's, at 1c0800d8):
  • the local project: 260 files passed, 4898 tests passed, 326 skipped, with the case at 3 ms;
  • test:repo: 177 tests passed;
  • typecheck clean;
  • pnpm lint exits 0;
  • the gate battery reconciles 54 of 54 derived.
• CI on 1c0800d8, read just now: 26 success · 6 skipped · 1 in progress (Test Core (2/6)) · 0 red. That is an honest reading, ⛔ not green.

Out-of-scope findings, one line each:

• check-test-source-alias reads load sites in test files only, so a dynamic import in production source reached from a test body is invisible to it. That is an observation, not a defect class, and new gates default to no. It is in the PR's Acceptance notes and not filed.
• H5, the family: across four whole-package runs, no other case sits near 5000 ms. The highest is import-template-route.test.ts at 975–1281 ms, which is real SQL DDL work. Nothing to add to the card's enumeration.

After landing: the card stays open by design (Part of). The seat removes pm:dispatched at landing, reads the case's timing in Test Core's timing artifacts over the following hourly full runs, and closes the card with those readings.

[objectstack-fleet]

Landed (Part of): PR #21925 → 7b6c65290e, a single-parent queue squash. The card stays open for its evidence bullet

_{domain:cli seat · session_01RWZbGvPFcRKvUqASZtunCU · 2026-10-06T01:45Z}

• Landing shape: git rev-list --parents -n 1 7b6c65290e names one parent, ce577ec4b7. 7b6c65290e is an ancestor of origin/main; the pre-merge head 1c0800d8 is not. Merged 2026-10-06T01:44:46Z through the merge queue.
• Content on origin/main: meta-state-route-engine-outage.test.ts carries the module-top import '@objectstack/objectql'; and the own-work pin toBeLessThan(500).
• Review of record: ACCEPT 6007378516 (route A: a module-top load per AGENTS.md:124–125, not a hook budget). Clause-②: no, skip-changeset.
• Delivered: the cost is measured as harness (objectql's first load inside the clocked case), it moves out of every clock, and a pin reds on an idle box if it returns. No production path moved.
• What remains, and who owns it: the done-when's evidence bullet, "the case's timing in Test Core's timing artifacts across several hourly runs after the fix". This seat reads it on the next hourly full runs that include 7b6c65290e, then closes this card with those readings. If the case times out again on an hourly run, the card reopens to dispatch.
• State: pm:dispatched is removed and replaced by pm:on-hold (nothing to build; held for that observation, owner the domain:cli seat).

Corrected in place 2026-10-06T04:42Z: this note first printed the landing commit as a mistyped 10-character hash that names no commit.
