Queue-flake anchor: src/engine-insert-static-readonly-strip.test.ts #21705

Description

@github-actions

src/engine-insert-static-readonly-strip.test.ts has ejected 2 pull requests from the merge
queue within a rolling 24 hours — 1 independent hit once
GitHub's speculative stacking is accounted for. This issue is the single place for
that conversation; it is refreshed by the merge-queue-triage workflow on every
further ejection.

PR stack queue build
#21700 S1 · inherited 37186683796
#21701 S1 · root 37186085048

⚠️ Queue depth is not evidence. The stack column is read out of the queue
branch names: GitHub builds each queued PR on top of the previous entry, so a
build whose BASE commit IS another victim's queue HEAD contains that victim's
tree by construction. A single deterministic break therefore ejects every PR
behind it, and the raw victim count climbs with QUEUE DEPTH until the owner
lands a fix. Start with the root above; an inherited row is a bystander until shown otherwise.

This issue is a NAME, not a diagnosis. The workflow that files it reads the
failing test file path out of the job logs and counts PRs; it does not
know whether this is a flake, a load/timing cliff, a semantic conflict between
queued PRs, or a real regression, and it does not act on any of those. No test is
skipped, quarantined or re-queued by it, and no PR is labelled by it — weakening
a gate stays a human act.

What to do with it: read one victim PR's triage comment for the failure REASON
line beside the FAIL line (a timeout and an assertion are the same FAIL line and
opposite diagnoses), decide the cause, and close this issue with the fix or with
the reason it is not one.

Last refreshed by queue build 37186683796 (PR #21700).

    Triage: first grade — tests · priority:p2 · domain:engine · pm:blocked (finding removed; queue-flake-anchor stays)

    Blocked-by: #21682

    Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-04T08:56Z. ⛔ Not a claim, ⛔ not a dispatch.

    Diagnosis: this is not a flake. The queue's own triage comment carries the failure REASON, an assertion on product behaviour: the platform's value reaches the driver: expected undefined to be 'stamp'. The cause is a deterministic semantic conflict, local to PR #21701:

    The fix is already on PR #21701. Its holder pushed b7d2799c8d, which fills a valid ISO-8601 instant and leaves what the pin proves unchanged. PR-side checks on that head are green so far (29 success, 1 pending), read in this round. ⛔ Not quarantined; the test is right.

    This card closes when PR #21701 lands green through the queue. The unlock scan closes it then rather than queueing it. If this signature appears again after that, it is a new hit.

    Not this card: the Console Pin Gate red in the same queue builds is a separate signature, filed as #21709 (a substring collision in the gate's staleness leg, not a leaked spec).
