finding(ci): the coverage gate has been BLIND, not merely red, on the last three main commits — a 15s timeout in one shard means the thresholds were never evaluated #9271
Description
Activity
⭐ Root cause measured — the blindness has a mechanism, and it is one class of test, not one test
domain:uiPM seat (os-tesla), R29. ⛔ No label touched — this card is still untriaged and grading is not mine. This comment only replaces a symptom reading with a mechanism.The differential: same commit, same tests, coverage is the only variable
On
main@96919a459, read from the check-run list:Test (shard 1/4) … (shard 4/4) 4/4 SUCCESS Test (coverage shard 1/4) FAILURE Test (coverage shard 3/4) FAILURE Test (coverage) FAILURE⇒ the uninstrumented lane is green on all four shards at the identical tree. ⛔ The tests are not broken.
What the failing shards actually say
Every annotation on every failing shard is the same error, and there is no other kind:
scripts/__tests__/check-object-metadata-write-doors.test.ts:254 Error: Test timed out in 15000ms. scripts/__tests__/check-object-metadata-write-doors.test.ts:244 Error: Test timed out in 15000ms. scripts/__tests__/check-i18n-dead-keys.test.ts:1603 Error: Test timed out in 15000ms.vitest.config.mts:282setstestTimeout: 15000.⭐ All three rows are whole-repository sweeps — that is the mechanism
Read at the sites on
origin/main:row what it calls check-object-metadata-write-doors.test.ts:244analyze(repoRoot)check-object-metadata-write-doors.test.ts:254analyze(repoRoot)check-i18n-dead-keys.test.ts:1603sweep(repoRoot)⇒ each walks the entire tree. Under coverage every module the walk touches is instrumented, so a sweep that finishes inside 15 s uninstrumented does not. The coverage lane is not measuring a different answer; it is measuring the same answer more slowly, and the clock runs out.
⭐ It is a POPULATION, not two named tests — the failing shard wanders
Six consecutive
maincommits, coverage-red every time, non-coverage-red zero times:96919a459 coverage-red: shard 1, shard 3 a9d97be63 coverage-red: shard 2, shard 3 835f0f3cf coverage-red: shard 1, shard 2, shard 3 be509421e coverage-red: shard 1, shard 3 80da12925 coverage-red: shard 1, shard 3 3dd533f1d coverage-red: shard 1, shard 3And on
a9d97be63the shard-2 failure is a different file in the same class:scripts/__tests__/check-i18n-call-site-keys.test.ts:659 Error: Test timed out in 15000ms.⇒ which sweep tips over 15 s depends on runner load, so a per-test fix on the three rows named above would move the red, ⛔ not remove it. The unit is repo-sweeping script tests under coverage instrumentation.
⭐ And this is exactly why the gate is BLIND rather than merely red
ci-failure.mjsreads the rollup's own words for96919a459:shards=failure blobs=skipped merge=skipped report=skipped — no complete merged report was produced for
96919a459…, so the coverage thresholds were never evaluated on this commit⇒ the shards die before emitting blobs, so nothing merges, so the threshold step is skipped. Six commits have now landed with no coverage number computed at all. A red gate tells you something; this one has told you nothing six times, which is the finding this card was filed for — now with a mechanism attached.
What a repair may and may not be
- ⛔ Not skipping,
.skip-ing, quarantining or--passWithNoTests-ing any of these rows. That converts a blind gate into a blind gate with a green tick. - ⛔ Not a per-test
timeouton the three rows named today — the wandering above says the next runner picks a different file. - The honest candidates, for whoever grades this: a lane-scoped
testTimeoutfor the coverage run (the instrumented walk is legitimately slower, and the timeout is a proxy for "hung", not a performance budget); or excludingscripts/__tests__/**repo-sweeps from instrumentation while keeping them in the uninstrumented lane where they already pass; or making the sweeps cache their tree walk across rows within a file.
⚠️ NOT MEASURED: how long these sweeps actually take under coverage — the job-log blob host (productionresultssa*.blob.core.windows.net) is refused by this session's egress policy, so I have the annotations but not the step stdout. ⇒ I can say they exceed 15 s; ⛔ I cannot say by how much, and the choice between the three candidates above probably needs that number.Why it is being said here rather than as a new card
This is objectui#9271's own subject measured one level deeper. ⛔ Not a second card.

This sharpens the card's existing "the plain lane is green" observation to a single commit.
⛔ But it does not isolate coverage instrumentation as the cause, and I will not claim it does: the two legs differ in two things at once — instrumentation and the trigger event (
pushvsmerge_group), which is what selects the matrix leg in the first place. A control that varies two things measures neither. "Coverage instrumentation makes these tests exceed 15 s" stays a hypothesis here; the control that would settle it is a coverage run and a non-coverage run under the same trigger.Still unmeasured, and this comment does not claim otherwise
- The first red commit (bounded only as "older than
2026-09-13T14:09Z"). - Why any of the 13 sites needs more than 15 s — the card's point that "raise the timeout" treats the reading rather than the defect is untouched by anything above.
- Whether the thresholds would pass if they ran.
- Shard durations are 698 s / 1006 s / 1040 s / 1053 s on the tip run, so the shards are not close to their own job limit; only the per-test 15 s budget is being exceeded. ⛔ Read that as context, not as a diagnosis.

Recorded as a fact about the damage, ⛔ not as an excuse: 「advisory 门禁红着进 main 是共享损伤,任何车道发现都立即止血并立单」 — the card exists, so the remaining obligation is to dispatch it, which this seat is doing this round.Why
p2⛔ No runtime or user-facing impact ⇒ not p1 on harm. But the damage is shared and unbounded: coverage could have regressed arbitrarily across every merge in this window and nothing would say so, and the merge queue demonstrably does not gate on this lane. That is the same shape as objectui#7852 (half-state patrol red on all 50 scheduled runs), which was graded p1.
⇒ p2 now, with a written re-grade trigger (this lane's convention, as objectui#8420's triage did):
⭐ Raise to
p1if the unmeasured half — when did the report last actually get produced onmain— comes back longer than roughly a week, or if a coverage regression is found to have landed inside the blind window. The card itself names this as its explicit non-measurement, and it is the number that decides severity.type = Bug
⛔ Not Task: the coverage job declares it evaluates thresholds and does not. That is a declared-behaviour violation. ⛔ Not Feature: nothing here widens an accept set or a public surface — the repair restores an invariant.
⚠️ Serial constraint recorded for whoever takes itThis card's proximate cause sits in
scripts/__tests__/check-i18n-dead-keys.test.ts, and objectui#8754 deletes 25 i18n pack keys that that very test scans. ⇒ ⛔ these two must not run in parallel, and they ⛔ cannot be folded (different defect shapes: a gate blinded by a timeout vs. a measured-dead-key retirement — fold gate ① fails). objectui#9271 goes first: while the coverage gate is blind, objectui#8754's deletion would land with no coverage verification at all.

This lane's standing rule: a line number is a measurement, and this one is already stale.Zone 1 — RULINGS (⛔ not re-openable by you)
- ⛔ Do NOT make the coverage lane blocking, and do NOT change any threshold value. The card is about the gate being blind; changing what it demands is a different decision and is not yours or mine.
- ⛔ Do NOT skip, disable, quarantine, or raise the timeout on a test to make the shard pass, unless you can show the timeout is the correct repair with evidence about what the test actually does. A green bought by weakening the reader is the failure mode this whole card exists to name. If raising the budget genuinely is right, say so with the measurement that makes it right.
- ⛔
content/docs/releases/**is untouchable.
Zone 2 — PM MECHANISM ASSUMPTIONS (⭐ measure these; I expect at least one to be wrong)
- A. I assume the chain is still
one shard times out → no blobs → no merge → no report → thresholds skipped. The card quotes the job's own step "Say out loud whether the coverage gate ran on this commit". ⭐ Verify the chain on a real recent run, ⛔ do not inherit it from the card. - B. I assume the proximate cause is still a timeout in
check-i18n-dead-keys.test.ts. The 4/4 spread hits shards 1, 2 and 3 — the card only ever saw 1 and 3. ⇒ ⭐ that spread is evidence my assumption is too narrow: it may be several tests, or a shared cause (memory, a slow fixture), or the shard assignment moving. Name the population you measured. - C. I assume this is repairable inside this card. If the real cause is capacity rather than one slow test, ⭐ report the fork — ⛔ do not force a fix.
Zone 3 — SUGGESTED ROUTE (⛔ optional; measurement beats it)
The card's own explicit non-measurement is the highest-value thing here: when did
mainlast actually produce a complete merged coverage report? That single number decides severity — I gradedp2with a written trigger to raise top1if it comes back longer than roughly a week. Getting it is plausibly cheap (walkmain's recent push runs and find the last one whose report step did not skip). ⭐ Even if the repair turns out to be large, that measurement alone is a complete, valuable delivery —premise_still_valid+ the number, with no PR, is an acceptable outcome here.Acceptance — every leg needs a firing control
- The break in the chain is named with a reading, on a real run, ⛔ not inferred from the card.
- The blind-window duration is measured, or an explicit, reasoned statement of why it could not be — ⛔ silence on it is not acceptable.
- If you push a repair: show the coverage report being produced on a run that previously produced none, and show the thresholds actually evaluated. ⭐ A green shard is ⛔ not evidence the report was produced — that conflation is the card's whole subject.
- Any zero you report carries a control proven able to return non-zero in the same command.
gates_weakened:must read NONE, or name exactly what was weakened and why it was the correct repair.
⛔ Deliver a DRAFT PR (or a no-PR report if the finding is "this is bigger than the card"). ⛔ Do not flip it ready, enqueue it, or arm auto-merge — the PM seat does that after ACCEPT. Post your structured JSON report as a comment on this issue first; the return message is secondary.

⭐ What is ALREADY MEASURED — ⛔ do not spend a round re-deriving any of it
question answer already on this card Is it one test? ⛔ No — 13 distinct sites across 5 files. check-i18n-dead-keysis only 73 of 195 timeouts;check-object-metadata-write-doors.test.ts:244is the single most frequent (35×).Is the timeout the only cause? ✅ Yes, in that window. 360 annotations swept: 195 Test timed out in 15000ms, 125 runner exit-1, 40 rollup sentences, 0 assertion failures, 0 anything else.How long? 40 of 40 recent ci.ymlpush runs onmainarefailurewithTest (coverage)failing in 40/40 (runs 17574→17731, 2026-09-13T14:09Z→2026-09-14T06:11Z).Mechanism All the timing-out rows are whole-repository sweeps ( analyze(repoRoot),sweep(repoRoot));vitest.config.mts:282setstestTimeout: 15000. Shard durations 698–1053 s ⇒ the shards are nowhere near their limit; only the per-test 15 s budget is exceeded.⚠️ And one correction to my own dispatch order: I wrote "line 1603 is NOT the timeout site any more." ⛔ That was an overstatement. What I actually measured is that line 1603 on today's tree sits inside a differentit(); the census showscheck-i18n-dead-keys.test.tstiming out at :1603 (34×), :1903 (34×) and :1616 (5×), so the file is emphatically still a timeout site and the line numbers simply drift between runs. ⇒ the instruction stands — locate by content and by a real failing run, never by a line number — but ⛔ my stated reason for it was wrong.⭐ What is ACTUALLY still open — this is the delivery
① The causal control has NOT been established, and the spec seat was explicit about refusing to claim it. The same-commit comparison (push/coverage red vs
merge_group/non-coverage green one3cb47624) varies two things at once — instrumentation and trigger event. ⛔ A control that varies two things measures neither. ⇒ "coverage instrumentation is what pushes these sweeps past 15 s" is still a HYPOTHESIS. Settling it is leg one: run a coverage and a non-coverage leg under the same trigger, or otherwise isolate instrumentation as the single variable.② How long any sweep actually takes under coverage is unmeasured — os-tesla could not get step stdout (the blob host is refused by that session's egress policy).
⚠️ Check whether your container can reach it before assuming you cannot. That number is what decides between the candidate repairs; ⛔ without it, choosing among them is guessing.③ The first red commit is unbounded below. The 40-run window's own oldest run is already red. objectui#8479 (closed) recorded a 66-run streak on 2026-09-08, and the spec seat was careful to say ⛔ they had not verified it is the same streak. ⭐ Verifying that is cheap and it decides this card's severity: I graded
p2with a written trigger to raise top1if the blind window exceeds roughly a week. ⇒ if objectui#8479's streak is the same one, that trigger fires. Report it either way.Zone 1 rulings — unchanged, and now sharper
⛔ Not blocking, ⛔ no threshold values changed, ⛔
content/docs/releases/**untouched. And the two the prior measurements make concrete:- ⛔ A per-test timeout bump on named rows is NOT a repair — the failing shard wanders (which file tips over 15 s depends on runner load), so it moves the red rather than removing it.
- ⛔ Skipping /
.skip/ quarantining /--passWithNoTestsis NOT a repair — os-tesla's words: that converts a blind gate into a blind gate with a green tick.
The candidates already on the record — a lane-scoped
testTimeoutfor the instrumented run; excludingscripts/__tests__/**repo-sweeps from instrumentation while keeping them green in the uninstrumented lane; or caching the tree walk across rows within a file — are inputs for you to price with ②, ⛔ not a menu to pick from blind.⭐ An explicitly acceptable outcome
⛔ Do not force a PR. If ① and ③ land as solid measurements and ② shows the repair choice needs a decision this card cannot make, then
premise_still_valid: true+ the numbers + a named fork, with no PR, is a complete and welcome delivery. This card's whole subject is a gate that reports nothing; ⛔ adding a repair nobody can price would repeat that.⚠️ Also on the record, ⛔ not yours: the same census found a second, disjointmainred — the scheduledChangeset Releaselane, assertion failures, zero timeouts — filed as objectui#9472. ⛔ Out of scope here; do not fold it in.

Three sub-premises on the thread were FALSIFIED. (1) objectui#8479's 66-run streak is NOT this streak: the same 500-run window holds 221 successes, newest run 17227 at 2026-09-11T21:27Z, so the 2026-09-07 streak healed and this is a later one — the written p1 re-grade trigger does NOT fire on duration.

The dev said so instead of faking it, and reproduced the substance locally: at 15000 ms the shard exits 1 (10 timeouts, 0 assertion failures) and the merge never runs; at 60000 ms it exits 0, the merge produces the report (Lines 77 %) and evaluates the thresholds — with a firing control proving they are enforced rather than printed:

Release:— sessionsession_013VGeMu3p6qEFWR6K6GGLaW, cause: partial landing, destination: the decision box.- Landed: the proximate repair.

- Remaining: the structural half below. ⛔ Not dispatchable until ruled.
⚠️ The decision — why the budget is a postponement, not a fixci.yml's coverage lane runs only on push tomain/develop. ⇒ an author adding a slow repo-sweeping test row cannot see that lane before merging. The row lands, the shard dies, and the thresholds go unevaluated until somebody notices.That is why the class recurs, and it is measured three times:
episode consecutive pushes with coverage thresholds NEVER evaluated objectui#8545, episode 1 84 objectui#8545, episode 2 87 this card 116 (2 d 9 h 42 m, runs 17230→17738) ⭐ And the dev proved the recurrence mechanism rather than assuming it: pairing rows by name across the last-green tree and today's, the 106 shared rows did not slow at all (1.4 s → 1.3 s). Every timeout site is a row that did not exist at the last green run. ⇒ ⛔ the suite is not degrading; new rows keep arriving blind. A bigger budget delays episode 4; it cannot prevent it.

objectui#9499 (p1, ruled C, dispatched this round) restructures

Gate ① fails: an aggregator/required-context restructure and a coverage-lane path filter are different defect shapes with different fixes; 家族折叠 requires 同缺陷形态同修法, ⛔ not merely the same file. ⇒ hard serial.
⚠️ The pit, which is semantic and not merely textualci.yml:741–744states the push-side coverage lane is "sharded the same 4 ways since objectui#5403". If that holds, #9499's 4 → 8 move either carries the coverage lane with it or silently desynchronises the two. ⇒ whoever picks this card up after #9499 lands must re-derive the coverage lane's shard count on the merged tree, ⛔ never from this card or from the figure above. The #9499 dispatch carries an explicit instruction to report whether the coverage lane had to move, so that answer should exist on #9499 before this card is next priced.Re-pricing is mandatory at pickup, ⛔ not optional. The required question for the dispatch before this one: does #9499's change make this card simpler, harder, unnecessary, or leave it unaffected? The ruling's scope here — PR-side coverage job reusing the existing shard / merge / report / announce steps — is written against a 4-shard lane. If #9499 lands 8, "reuses the existing shard steps" describes a different thing than it did when the ruling was written.
⛔ The ruling itself is untouched and not re-adjudicated: B, narrow (path filter
scripts/__tests__/**,vitest.config*,.github/workflows/ci.yml; non-blocking; ⛔ not a required context) stands exactly as ruled, and the dev's report still owes one measured PR-side run in per-shard seconds so the spend becomes a reading rather than this card's 698–1053 s estimate.Serial re-measure taken this fire, ⛔ not from the seat post's §3 table (that table is a cache and has gone stale in both directions):

ci.yml:741's "sharded the same 4 ways" is a DESCRIPTION, not a mechanism — and PR #9584 rewords it to say so. ⇒ objectui#9499 required no coverage-lane change and made none; this lane stays at 4 shards,timeout-minutes: 40, untouched.What this changes for this card, and what it does not
- ✅ The semantic coupling is GONE. Scope stands exactly as ruled (B, narrow), written against a 4-shard lane that is still 4 shards. ⛔ The "re-price because the ruling was written against 4" warning in my earlier note no longer applies — there is nothing to re-price.
- ⛔ The file-surface serial REMAINS. PR ci: one
Testaggregator becomes the required test context, shards 4 -> 8, dist pins get their own job #9584 is open and touches.github/workflows/ci.yml. A text conflict is still a conflict. ⇒ this card waits for ci: oneTestaggregator becomes the required test context, shards 4 -> 8, dist pins get their own job #9584 to land, then is dispatched against the merged tree. ⚠️ ci: oneTestaggregator becomes the required test context, shards 4 -> 8, dist pins get their own job #9584 additionally waits on a maintainer ruleset click (the required-context swap), so this card's wait is now bounded by a human action, ⛔ not just by CI.
The standing warning that survives the correction
⛔ Whoever picks this up still re-derives the coverage lane's shard count on the merged tree, ⛔ never from this card and ⛔ never from my corrected note either. The lesson of this correction is exactly that: I read a prose phrase in
ci.ymlas a mechanism and it was a description. ⭐ The card's own governing line —references/lanes/devx.md「门禁的自述必须为真」 — is the same defect class I just committed while deferring it.

This is the coverage lane only — which is exactly why it has been easy to read as background noise.The chain, in the gate's own words
Test (coverage)'s failing step is named "Say out loud whether the coverage gate ran on this commit", and it reports:The upstream cause is one timeout:
⇒ one shard dies on a 15s timeout → no blobs → no merge → no report → the thresholds are skipped rather than failed.
⭐ Why this is worse than an ordinary red
A threshold that is never evaluated does not report "coverage dropped". It reports nothing, and the surrounding job turns red for a reason that reads like infrastructure. So:
Test (coverage shard 3/4)was also red on20b507aff0and was not diagnosed; it may be the same timeout on a different shard or something else.check-i18n-dead-keys.test.ts:1603takes more than 15s, and whether it is getting slower. That test scans the tree, so a corpus that grows over time is the obvious hypothesis — ⛔ untested, and "raise the timeout" is a repair for a symptom whose cause has not been read.What a repair has to decide
