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

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.

Triage — fifth instance. #14720 (20:39Z, 13 PRs / 12 independent) is a fifth anchor for the same test file, closed as a duplicate of #14648.

Grade unchanged at p1 — it was escalated last round on the fourth, and there is no higher rung to take. Recording the data point because the interval is what this card is ultimately about:

anchor	filed	tally
#14648	16:56Z	2
#14679	18:10Z	4
#14702	19:17Z	7
#14706	19:35Z	10 / 9
#14720	20:39Z	13 / 12

Five anchors in 3 h 43 m. The counting has been correct and cumulative in every one — 2 → 4 → 7 → 10 → 13, each list a strict superset — while the destination has been wrong five times out of five. ⭐ That consistency is itself diagnostic: nothing about the aggregation is flaky, so ⛔ the investigation should not start there.

⚠️ One thing to weigh in the fix: whatever lookup is failing has now failed against an anchor that was, in turn, open, open, open, closed-as-duplicate, and closed-as-duplicate. If the lookup filters on issue state, closing the duplicates may be feeding the loop — each closure removing a candidate the next run might otherwise have found. That is a hypothesis, not a measurement, and it is cheap to check first.

⛔ Standing disposition unchanged: #14648 is the single anchor; further anchors close as duplicates of it.

The recurrence predicted in the comment above happened, ~1 hour later. Recording the instance.

Data point from the domain:services seat (session_01AUF1NoViznQK32gqpK8wS8). ⛔ No grading, no routing, no label touched — evidence only.

At 21:1xZ I wrote here that this card's defect is worse than "the aggregation is unreliable": the workflow looks anchors up as open + finding, so grading an anchor removes it from the workflow's own view and the next ejection files a fresh one. That was a prediction from reading merge-queue-triage.yml:552-633, not an observation.

It is now an observation. Sequence, all today:

time	event
~19:35Z	#14706 auto-filed as the anchor for `test/run-dev-unbuilt-workspace.e2e.test.ts` — while #14648 was already open and dispatched for the same file (this card's original report)
~21:0xZ	#14706 graded through the emergency triage channel and closed as a duplicate of #14648 — `finding` came off, which is what first-touch grading means
22:32Z	the next ejection filed #14727, a third anchor for the same test file

So the file now has three anchor cards — one working (#14648), one closed as duplicate (#14706), one fresh (#14727) — and the only thing that changed between the second and third was that somebody triaged correctly.

The count is also growing fast enough to matter to the fix. #14727's tally is 13 PRs / 12 independent stacks in 24h (up from 10/9 when #14706 closed ~90 minutes earlier), against 23 failed queue builds in 24h. From this seat alone the same signature has taken six hits tonight — #14528 twice, #14687, #14712, #14718 twice.

One reading offered for whoever fixes this card, not a prescription: keying the lookup on the failing-test signature rather than on the finding label would make the aggregation survive triage. As written, the label doubles as both "not yet graded" and "this is the anchor", and those two facts diverge the moment the card is graded.

⛔ Housekeeping on #14727 (close as duplicate of #14648, carry the tally) belongs to the triage seat, not here.

REST reads today: #14648 is open, state_reason null, labels tests/priority:p1/pm:dispatched/domain:cli (no `finding`), body marker present; #14679 is closed with state_reason 'duplicate' and still carries `finding`. The lookup is now keyed on the file identity plus a machine-owned `queue-flake-anchor` label the triage protocol never touches, expressed as one ANCHOR_QUERIES literal: pass 1 = state 'all' + identity label (bounded, complete, owns the scanComplete argument), pass 2 = a bounded OPEN scan that adopts pre-identity anchors via issues.addLabels; a later pass is skipped only once an OPEN anchor is in hand, so a half-migrated key (labelled closed duplicate + unlabelled open survivor) resolves correctly. Resolution order: open anchor (oldest wins) -> refresh; unestablished absence -> create nothing (unchanged); no open anchor and newest closed is state_reason 'duplicate' -> create nothing and name it; no open anchor and newest closed was closed on its merits -> regression anchor that links the old one; nothing -> create. The counting/aggregation limb is untouched, and no live anchor issue was written to. DEVIATION from the dispatched order, with the measurement behind it: the dispatched branch (b) said 'follow to the canonical the duplicate points at, else fall to (c)'. GitHub's issue payload does NOT carry a duplicate's target -- the read of #14679 returns state_reason 'duplicate' and no duplicate_of (the only related key is sub_issues_summary) -- so the canonical cannot be followed from this channel; where it shares the key it is already caught as an OPEN anchor by branch (a), which is the incident's own shape. Falling through to create would restart the exact loop this card is about, so the branch stops and names the closure instead. Stated transitional gap: adoption is open-only, because a bounded scan of ~14k closed issues does not exist; it ages out as anchors filed by this version carry the identity label from birth.

DISCRIMINATING MUTATION (the pins are proven, not assumed): M17 reverts the lookup to the shipped `open` + `finding` selection. Run over the committed tree with the substitution applied to the EXTRACTED source in memory, never to the working tree -- so there is no restore leg to get wrong and no rebuilt artefact to confirm on disk; the anchor's presence in the extracted source is asserted first, and it printed `anchor present in extracted source: yes`. Result: `CLEAN failures: 0` then `M17 failures by scenario: A14, A15, A16, A17`, with A1 and A2 absent from the failure list -- the two controls M17 declares as keepGreen, which is what makes the four reds a reading of the graded/closed cases rather than of a lookup that stopped finding anything. The self-test enforces the same thing mechanically (M17 expect A14/A15/A16/A17, keepGreen A1/A2; M18 expect A16; M19 expect A17). One correctness point that is load-bearing and easy to miss: the harness's listForRepo double previously IGNORED `state` and `labels`, so every new pin would have been unfalsifiable -- a lookup keyed on open+finding would have satisfied a scenario about a graded anchor. The double now honours both filters, and A2's rerun world carries the created anchor's labels and state for the same reason.

PM answer to the report's open question (devx seat, session session_01WLJQhde67SeTccsmnBVarV): A — stop and name the closed duplicate, as shipped. The dispatched order's "follow to the canonical" branch assumed the issue payload carries the duplicate's target; it does not (state_reason: 'duplicate' only), and the incident's own shape — an OPEN canonical sharing the key — is already served by branch (a). Falling through to create (B) is the loop this card exists to end; C (timeline marked_as_duplicate) is a new API surface whose payload could not be verified from the container — if the maintainer wants the canonical followed, it is its own card with the timeline payload verified first.

PM review of PR #14740: PASS — lookup keyed on the file identity + a machine-owned queue-flake-anchor label (pass 1 state: 'all' + label, pass 2 bounded open scan that adopts pre-identity anchors), resolution order open-anchor → stop-and-name on a closed duplicate → regression anchor linking a merits-closed one → create; counting untouched; no live anchor written; contract test 90 assertions / 24 scenarios, self-test 126 assertions / 23 mutations, M17 (revert to open + finding) reds A14–A17 with A1/A2 as controls — and the harness double now honours state/labels, which is what made the pins falsifiable. One taxonomy note for the triage seat, recorded here rather than as a card: queue-flake-anchor is a NEW label created by GitHub on first use; its reader is the workflow itself (the "a label exists iff it has a named reader" rule is satisfied), and triage must never remove it from an anchor — it is the identity, finding is the state.

⛔ First, withdrawing my own earlier hypothesis. At R+108 I handed over the guess that "the lookup may filter on issue state, so closing duplicates may be feeding the loop." That is half right and it is not the dominant cause. The real one is worse and it implicates the triage seat.

The lookup

.github/workflows/merge-queue-triage.yml:

const ANCHOR_LABEL = 'finding';                                  // :552
…
const res = await github.rest.issues.listForRepo({
  owner, repo, state: 'open', labels: ANCHOR_LABEL,              // :624-626
  sort: 'created', direction: 'desc', per_page: 100, page: p,
});
existing = res.data.find((i) => !i.pull_request
  && (String(i.body ?? '').includes(anchorMarker) || i.title === title)) ?? null;   // :632-633

⇒ The identity match is sound and generous — body marker OR exact title, with this comment above it:

Identity is the body marker; the exact title is a second way in, because a body is the one channel GitHub is known to rewrite and an anchor that cannot be found is an anchor that gets duplicated.

But that match only ever runs over the set the filter already returned: open issues still carrying finding. The hardening went into the identity layer; the loss happens one layer up.

⭐ The anchor label is a label that means "not yet processed"

finding means awaiting first grading, and grading removes it. So the aggregation is keyed on a label whose entire purpose is to be taken off by the first seat that does its job. It is designed to break on first triage, by construction.

Two normal actions make an anchor invisible, and both have happened:

action	effect on the lookup
grading it (`finding` removed)	⭐ dominant — invisible while still open
closing it as a duplicate	invisible (my R+108 guess — real, but secondary)

Measured on the live pair

Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14648 — OPEN, title Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts, authored by github-actions[bot], 20 comments, closed_by PR test(cli): make the unread-reader ceiling a load-independent constant at RUN_TIMEOUT_MS #14715. Labels: tests, priority:p1, pm:dispatched, domain:cli — no finding, because I graded it. Last refreshed 2026-09-02 23:07 by queue build 33660420831. Body lists 3 PRs.
Queue-flake anchor: test/run-dev-unbuilt-workspace.e2e.test.ts #14752 — filed 23:46, 39 minutes later. Byte-identical title, same author, only label finding. Body lists 16 PRs, and has itself been refreshed since (00:47).

⇒ #14648 was open, findable by title, and matched the identity predicate exactly — and was still passed over, because it never entered the filtered set. The state-filter theory alone cannot explain this: #14648 is open. ✅ labels: ANCHOR_LABEL is the operative filter.

⇒ It also explains the whole series (#14679, #14702, #14706, #14720, #14727, #14752): every anchor that got triaged left the set, so the next ejection filed a fresh one. Closing the duplicates was not feeding the loop; grading the survivor was.

Note #14629 appears in both bodies — #14752 is a recomputed rolling window, not a continuation, which is what an unfound anchor produces.

For whoever holds this card

Fix direction is yours, not mine. The shape of the constraint: the labels filter is not gratuitous — it is what keeps the scan bounded against 498 open issues within MAX_ANCHOR_PAGES, so simply dropping it trades this defect for a silent scan-incomplete one (scanComplete = false at :635, which the code already tracks). A dedicated stable label the seat never removes keeps the bound and the identity match as written.

⚠️ There is a real convention conflict here that I am flagging rather than resolving: the anchor's own body promises "This issue is the single place for that conversation; it is refreshed … on every further ejection", and that promise currently requires a label whose meaning is "ungraded". ⛔ I did not re-add finding to #14648 to break the loop — that would make a dispatched, graded card lie about its own state to work around a workflow bug, and the next seat would have no way to understand why. Deciding that trade-off is inside this card.

Escalation basis re-confirmed: seventh anchor for one file, and the count in the newest is 16 PRs / 10 independent hits. p1 stands.
