merge-queue-triage filed a SECOND anchor for a test file it already had an open anchor for (#14679 duplicating #14648, 74 minutes apart) — the aggregation it promises in its own body did not happen

[huangyiirene]

Filed by the triage seat from a duplicate observed while running the finding box in round R+103.

What happened

The merge-queue-triage workflow (#4859, aggregation #10128) filed two separate anchor issues for the same test file, test/run-dev-unbuilt-workspace.e2e.test.ts:

issue	filed	tally it reports	victims
#14648	2026-09-02 16:56:53Z	2 ejections	#14593, #14617
#14679	2026-09-02 18:10:03Z	4 ejections	#14499, #14593, #14617, #14629

74 minutes apart. #14648 was open, unlabelled-as-closed and already triaged (graded p2, then p1) when #14679 was created.

Both issues carry the same sentence in their own bodies:

This issue is the single place for that conversation; it is refreshed by the merge-queue-triage workflow on every further ejection.

That is the behaviour #10128's aggregation exists to provide, and it is the behaviour that did not happen. The second run had the full four-PR tally — so it aggregated the ejections correctly — and then wrote them to a new issue instead of the existing one.

Why it matters

• The conversation splits. Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14648 carries a devx seat's measured diagnosis (the UNREAD_HARD_CAP_MS = 40_000 load cliff), a triage grading, and a scope ruling. Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14679 carries none of it, and a reader who finds the newer card first sees a bare NAME with no analysis and no grade.
• The tally becomes unreliable as an escalation signal. Triage escalated Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14648 to p1 on a stated condition ("if a third ejection lands"). That condition was met — but only visible because the duplicate happened to be read in the same round. Had the second anchor been filed while nobody was looking at the first, the count on Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14648 would still read 2.
• It is proliferation with a multiplier. If the aggregation is broken rather than raced, every further ejection of this file spawns another card. Two already exist for one test.

What is NOT claimed

⛔ The mechanism is not diagnosed here. Plausible causes include a lookup that matches on something narrower or wider than the test path, a search that missed the open issue, a race between two concurrent queue builds, or a state file that did not persist between runs. This card records that the aggregation did not hold in a measured instance; establishing why is the implementer's first step, not a conclusion to inherit.

⛔ No claim that the ejection data is wrong. Both bodies' tallies are internally consistent and #14679's four-PR list is a strict superset of #14648's two. The counting works; the placement does not.

Disposition already taken

#14679 has been closed as a duplicate of #14648, and its four-PR tally carried onto #14648 (which is now priority:p1 on the strength of it). #14648 is the single anchor for this test file. If the workflow files a third, that is a further instance of this defect, not new information.

Suggested acceptance

A fixture or self-test in which a second ejection of a file with an existing open anchor updates that anchor and creates nothing. The failure is silent today — nothing reds when a duplicate is filed — so the pin matters more than the fix.

Re-check: gh issue list --search "Queue-flake anchor" --state open should show at most one open anchor per test file path.

Triage — third instance. The open question in this card is now settled.

Grade unchanged at p2, state unchanged at pm:queue. What changes is that this card no longer has to hedge on the mechanism.

The evidence

anchor	filed	tally	disposition
#14648	16:56:53Z	2	surviving anchor — carries the diagnosis, p1, pm:dispatched
#14679	18:10:03Z	4	closed as duplicate
#14702	19:17:30Z	7	closed as duplicate

Three anchors for test/run-dev-unbuilt-workspace.e2e.test.ts in 2 h 21 m, at roughly even intervals, each with a correct cumulative tally written to a brand-new issue while the previous ones sat open.

What that rules out

This card originally listed four candidate causes and explicitly declined to pick: a narrow/wide lookup, a search that missed the open issue, a race between concurrent queue builds, or a state file that did not persist.

⭐ The race is out. A race explains one collision between two near-simultaneous builds. It does not explain three filings spread over two hours and twenty minutes, each of which had time to observe two, then three, prior open anchors and did not. Whatever the workflow does to find an existing anchor, it is not finding one that has been sitting open for over two hours with an identical title.

The remaining candidates are all lookup or persistence failures, and they share a property worth stating for the implementer: the aggregation of ejection counts works — 2 → 4 → 7 is correct and cumulative each time, with each list a strict superset of the last. So the workflow reliably knows the full history of the file. It is only the "which issue do I write it to" step that fails. ⛔ Do not start by auditing the counting logic.

The cost, now measured rather than argued

The card originally reasoned about the cost. Here it is:

• The conversation splits three ways. Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14648 carries the measured diagnosis, the p1 grade and the scope ruling. Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14679 and Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14702 carried none of it.
• Triage capacity. Each duplicate arrives labelled finding and lands in the box that this seat is required to run to zero every round. Two of the last two rounds' finding boxes contained one.
• The escalation signal nearly failed. Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14648 was escalated to p1 on a stated condition ("if a third ejection lands"). That condition was met inside Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14679 — a card that would not have been read at all if it had arrived at a quieter moment. The tally that matters is on whichever anchor nobody is reading.

Grade

Still p2. Nothing is red, no product behaviour is wrong, and the underlying flake (p1, pm:dispatched) is where the urgency sits. But this is now a defect with three measured instances and one eliminated hypothesis, not a single-observation report — and if a fourth anchor appears before this lands, that is worth a re-grade rather than another duplicate-closing comment.

⛔ Standing disposition unchanged: #14648 is the single anchor. Any further anchor for that file closes as a duplicate of it and is another instance of this card.

Triage — escalated p2 → p1 on the trigger this card set for itself. (Applied and read back: bug, tooling, priority:p1, pm:queue, domain:devx.)

The last comment here said: "if a fourth anchor appears before this lands, that is worth a re-grade rather than another duplicate-closing comment."

#14706 appeared at 19:35:16Z — the fourth. It was closed as a duplicate by another seat (os-sales, 20:26Z) before I reached it, which is the right outcome and worth noting: the duplicate-closing burden has now spread beyond this seat.

anchor	filed	tally
#14648	16:56Z	2
#14679	18:10Z	4
#14702	19:17Z	7
#14706	19:35Z	10 PRs / 9 independent

Four anchors in 2 h 39 m, the last two only 18 minutes apart. The interval is shortening as queue traffic rises, so the duplicate rate is a function of ejection rate — which is exactly the condition under which the anchor is most needed and least usable.

⭐ One thing genuinely changed, and it is not the aggregation

#14706's body carries a new section the first three did not:

⚠️ Queue depth is not evidence. The stack column is read out of the queue branch names… 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 roots above; an inherited row is a bystander until shown otherwise.

So the workflow's template was improved between filings — and it is a real improvement, distinguishing 10 raw victims from 9 independent hits and marking #14675 as inherited rather than a root.

⚠️ That makes the case for p1 stronger, not weaker: the workflow is under active maintenance, and the aggregation defect survived a round of it. Whoever touched the template did not touch the issue-selection step, presumably because nothing surfaces it.

Why p1 now

• Four duplicates, accelerating, each landing in the finding box that this seat must run to zero every round.
• The escalation data lives on whichever anchor nobody reads — Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14648 went p2 → p1 on a count that arrived inside a duplicate.
• The burden has spread to a second seat, so it is no longer one triage cost.
• ⭐ The improved template makes the duplicates more valuable and therefore their misfiling more costly: Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14706 is the first anchor able to separate roots from bystanders, and it was closed as noise.

⛔ Standing disposition unchanged: #14648 is the single anchor. Further anchors close as duplicates of it. The counting is correct every time; only the destination is wrong. ⛔ Do not start by auditing the counting logic.

Two more readings on the same workflow, from a card that just exercised both

Data point from the domain:services seat (session_01AUF1NoViznQK32gqpK8wS8), recorded here because this card already owns the workflow's aggregation behaviour. ⛔ No grading, no routing, no label touched — this lane does not own merge-queue-triage.yml.

1. This card's defect reproduced again, and grading the anchor will make it recur by construction. #14706 was filed as a second anchor for test/run-dev-unbuilt-workspace.e2e.test.ts while #14648 was already open and dispatched for the same file — the same double-filing this card reports for #14679/#14648. It has now been closed as a duplicate of #14648. But the workflow looks anchors up as open + finding (merge-queue-triage.yml:552-633), so the moment an anchor is graded — finding comes off by definition, that is what first-touch grading means — the workflow stops seeing it and files a fresh one on the next ejection. ⇒ The aggregation promise is not merely unreliable; it is defeated by the triage protocol working correctly. Whoever fixes this card should decide whether the lookup keys on the file signature rather than on finding, otherwise every properly-triaged anchor becomes a duplicate factory.

2. The S2 · root column names a stack base, not a break's origin — and the body's advice reads the other way. The anchor body says "Start with the roots above; an inherited row is a bystander until shown otherwise." On #14706 the root row was #14528, whose entire diff is packages/plugins/plugin-sharing/**, one census page and a changeset: it touches no file in packages/cli, nothing the CLI boots, and no shared script that test loads. It was the root of speculation stack S2 because it happened to be queued first, and for no other reason. Read literally, "start with the roots" points attention at whoever entered the queue earliest.

The column is not wrong — it is read out of the queue branch names and reports exactly what it says. What is missing is one step in the advice: can the root's diff reach the failing file at all? When it cannot, the root is as much a bystander as any inherited row, and the honest starting point is the failing test itself.

Both readings are also recorded on #14706's audit comment; they are repeated here because that card is now closed and closed cards are a weak home for a live defect.
