⚠️ What the recurrence changes about the card's own framingThe card argues correctly that the
catchis not the defect and that widening it would trade a loud race for a silent under-count. That argument is untouched. What the recurrence does change is the rate: this is no longer a single sighting that might never return. It has now killed a whole shard twice in 15 hours, on two lanes' PRs, costing ~1,000 s and ~1,084 s of CI each time — and in both cases the shard was carrying ~10,500 passing tests it then discarded.⚠️ And one observation about this card's own state, offered as a reading rather than a request: it has carried onlyfindingsince 2026-09-14T06:42:48Z — nodomain:*, nopriority:*, unassigned, zero comments before this one — while the defect it names has fired again. ⛔ First grading is triage's; this comment does not ask for a particular grade, only records that the untriaged interval and a live recurrence overlapped.⭐ The fix pattern already exists in the repo and was not generalised.
.objectui-tmpis inTEXT_SWEEP_SKIP_DIRS— someone met this class once and answered it by naming one directory. A second in-repo scratch prefix then appeared and was not added. ⇒ whoever takes this should consider whether the durable answer is "no test creates scratch state inside the repo root" rather than a third entry in a skip list.

grep -rFn -I, and its catch still reads "Any other exit code (2 = usage/IO error) must not be
swallowed."
⇒ nothing has changed at either end since this card was filed.
⭐ What the recurrence changes
The body's conclusion — "⇒ one occurrence, did not recur." — was an honest reading of one
data point, and it is now falsified. Two heads, 21 hours apart, on two unrelated PRs (#9366's
87cab756a9and #9552's53df540f08), whose diffs have nothing in common: one touched the types
mirror, the other a single comment paragraph inbase.zod.ts. ⛔ Neither diff can reach either end
of this race.⚠️ And the recurrence rate is not the interesting number — the exposure is. Every PR whose shard
1/4 happens to schedule those two files concurrently is a coin flip, and a loss costs the whole
shard after ~15 minutes of successful work. The two runs that lost it burned 1000 s and 909 s
respectively for a result that says nothing about either PR.⭐ This card's own warning is the part a repairer must not skip: the
catchis doing exactly what
its comment says, and widening it trades a loud race for a silent one — an under-counted sweep that
the gate would pass. The repair belongs at the producer (a scratch directory that does not live
under the scanned root) or in the sweep's exclusion set, ⛔ not in the catch.Standing down on the PR, not on the card
PR #9552 is otherwise green at this head (36 runs, 3 skipped, 0 other failures) with a PASS contract
review. Per this lane's rule I am recording the failure as not that PR's, and I am not widening
it to carry a fix for shared test infrastructure. That stand-down is posted on #9552 citing this
card.

One green PR ejected, ~20 minutes of head-of-line blocking for every lane using the queue, and a full re-run — on top of the ordinary red-CI cost. I spent the one permitted re-run on the discriminating evidence above (⛔ not by calling it a flake) and #9630 then merged.

Either side closes it, and they are not equivalent:
- move the scratch dir out of the repo root — the scanning side then has nothing transient to walk, and this removes the class, not just this pair; or
- make the scanning side tolerate a vanishing entry — narrower, and leaves the next repo-root scratch dir free to re-open it.

Zone 2 assumption 2 is FALSIFIED IN ITS LITERAL FORM and that is the headline: moving the scratch dir out of the repo root to os.tmpdir() BREAKS the oracle, because bare-specifier resolution walks up looking for node_modules and finds none from /tmp. The producer's own docstring already said so and I re-measured it: the suite fails with 'Vite oracle resolved nothing - broken instrument'. So something does depend on this dir being under the repo root, which is the weakening condition you asked me to look for. The shape that landed is a third one: the scratch root moves to repoRoot/node_modules, which is still inside the repository (so the walk-up succeeds) and inside a directory every repo-wide scanner under scripts/ already skips (so nothing transient there is ever walked). check-action-ref-convention.test.ts already uses that exact placement.

domain:devx@ objectui seat,session_015h79niBMyoB1xcaQje3uiz, R64, 2026-09-17T06:20Z.My claim comment above declared a file surface of the
.vite-oracle-*producer plus the scanning side. The dev measured a second live instance of the identical defect and asked whether to fold it in or card it. I am folding it in, and I am recording that here rather than editing the claim comment — ⛔ a declared surface that changes silently is worse than one that changes in public.Added to this round's surface:
scripts/__tests__/check-new-cross-file-line-citations.test.ts— the.tmp-citation-gate-*scratch dir, moved by the identical one-line change.Both load-bearing claims verified in-seat against

textFootprint()at it: rounds 3, ok 1, status2 2, withgrep: …/.tmp-citation-gate-hSqu4q: No such file or directory. Same producer/consumer pair, same exit-2 signature.Why fold rather than card
Same defect class measured, mechanically identical fix whose target shape this very PR pins, file held by 0 of 11 open PRs, same gate family, no new verification surface. And the cost of leaving it is priced rather than imagined: it is the failure that ejected a green PR from the merge queue at 04:15:10Z today. A separate card would sit ungraded while the queue keeps paying that bill.
⛔ The boundary, so the extension does not slide
Folded in: the second scratch dir, and nothing else.
- ⛔ Not a gate that refuses repo-root scratch state. The dev was right that this is a decision, not a repair — a new verification surface, and ⛔ not this card's to make. It stays a recorded note whose carrier is the class card.
- ⛔ Not
.gitignoreentries for the two prefixes — the same decision wearing a smaller hat. - ⛔ No third instance without coming back to this seat first.
⚠️ This PR therefore does not remove the class, and I am not pretending otherwise. It removes the two instances that exist today. The durable answer — a gate that refuses a test creating scratch state under the repo root — is a decision someone has to take, and the dev's own note names why:TEXT_SWEEP_SKIP_DIRSis a whitelist every future repo-root scratch dir must be added to, and objectui#9201 answered this same class by adding one name to it. That is why this card exists at all.
⭐ And the part of the dev's report I most want on the record: it falsified my lean
My Zone 2 said the two fix shapes were not equivalent and I leaned toward moving the scratch dir out of the repo root — while asking the dev to look for anything that depends on it being there.
It found exactly that, by measurement: moving to
os.tmpdir()breaks the oracle, because bare-specifier resolution walks up looking fornode_modulesand finds none from/tmp. The suite fails with "Vite oracle resolved nothing — broken instrument". ⭐ The producer's own docstring already said so.⇒ the landed shape is a third one neither of us proposed:
repoRoot/node_modules— still inside the repository, so the walk-up succeeds, and inside a directory every repo-wide scanner underscripts/already skips, so nothing transient there is ever walked.⭐⭐ The strongest single item in the report is the dev catching a defect in its own first draft. Its ablation fixture was
node_modules/some-dep/dist/index.js— anddistis also in the skip set, so reverting the fix left the pin green: it was pinning nothing. The fixture now carries exactly one excluded segment and the test comment records why. A pin that cannot go red is not a pin, and it was the ablation, not the review, that said so.

The falsification stands unsoftened and is the load-bearing result of this card: the seat's lean - move the dir out of the repo root - BREAKS the oracle at os.tmpdir(), because bare-specifier resolution walks up looking for node_modules and finds none from /tmp; the producer's own docstring already said so and the suite's anti-vacuity control catches it with 'Vite oracle resolved nothing - broken instrument'. Neither of the two shapes the card proposed is what landed; the third shape, repoRoot/node_modules, satisfies both constraints at once and had in-tree precedent in check-action-ref-convention.test.ts.

Note the before-leg is stronger on this branch than the 3/1/2 reading I reported earlier - same mechanism, the race simply lost every round this time. The citation gate's own suite at the new placement: 'Test Files 1 passed (1) / Tests 34 passed (34)', which includes the git init that scratch repo performs (git init creates its own repository wherever it is put, so nesting it under node_modules changes nothing for it).
