domain:uiseat). The assignee and this comment are set by the PM on the dev's behalf — the dev inherits both, posts no second claim, and ⛔ never writes the assignee field.⭐ Scoped deliberately — this is NOT "fix all seven"
The card's own instruction is "listed, not fixed here — each needs its own component-level diagnosis the way this one got it." Seven full diagnoses in one pass would be the batch-repair mistake the card warns about. So:
REPAIR the two that are vacuous in the refusal direction TODAY — these prove nothing right now, which is worse than being flaky:
plugin-dashboard/ObjectPivotTable— the wait isqueryByTestId('pivot')while the refusal arm expects 0 on that same node, so "drawn empty" and "drawn before the data" are one reading.plugin-gantt/ObjectGantt— the inverse gap: the refusal arm readsbars === 0right after a wait onfindmerely having been called, with no completion anchor.
DIAGNOSE, ⛔ do not repair, the other five (
plugin-calendar/ObjectCalendar,plugin-charts/ObjectChart,plugin-dashboard/ObjectDataTable,plugin-map/ObjectMap,plugin-timeline/ObjectTimeline). For each: name the component-side mechanism, say whether the wait actually fails to gate the read, and state what a repair would anchor on. ⭐ A file you correctly leave alone with a measured reason is worth as much as one you repair.⚠️ The measured zero that made this card, and its stated sensitivityall nine family files, five iterations under the same 6-way load — zero failures. That instrument is too weak to clear them: the pre-fix tree file's own observed rate was ~1 in 12, and five runs would miss an 8%-per-run flake roughly two thirds of the time.
⇒ ⛔ do not use a green loop as evidence that a file is fine. The two vacuous ones are not flaky at all — they are always green and always meaningless, which no repetition count can detect. Diagnose at the component, as objectui#8664 did.
The worked example — read it, ⛔ do not port it
objectui#8664 / PR #8664 is the sibling that got a real diagnosis:
- the testid it waited on was on the table wrapper — a mount signal — while the rows it counted arrived a commit later, because
ObjectTree'sexpandedis auseStatemirror re-seeded by auseEffect; - a probe recorded every DOM state the fixture passes through and evaluated both waits at each: the old wait's first passing state was
table:1rows, where it yields 1 — the CI red by construction rather than by luck; - ⭐ the positive arms were repaired to wait for the descendant row the mirror gates, then assert the drawn shape (label + depth per row), because "a count alone is also satisfied by a tree that flattens everything, and by a fix that merely waits longer";
- ⭐ the refusal arm cannot wait for an absence, so it anchored on the tree's own "No records" panel, which renders only after
loadingflips false — "so this arm cannot pass by timing out, which is the failure mode every absence-shaped pin has."
⚠️ ⛔ Do NOT assume that shape transfers. That PR's own write-up records that the kanban twin's shape did not transfer to the tree —plugin-treehas no lazy boundary anywhere, so only the mirrored-state half applied and the symptom differed (expected 1 to be 2, a partial draw, vs kanban'sexpected +0 to be 2, nothing drawn). ⭐ Checking is what caught it.plugin-chartsin particular does have a lazy boundary and is the closest kin to kanban — that is a hypothesis to test, not a conclusion.The evidence bar, per repaired file
- ⭐ Leg 1 is the deliverable: force the unfavourable ordering and observe the old wait produce the wrong answer — red, or (for the vacuous pair) green-while-meaningless, demonstrated by making the component draw the thing the refusal arm claims is absent and watching the arm still pass. ⛔ Without leg 1 you have not distinguished a fix from a coincidence.
- the new wait correct under the same forced ordering;
- the new wait still correct under the ordinary ordering.
⚠️ RTL'sasyncWrapperdrains one macrotask before returning, sosetTimeout(…, 0)sits inside its own drain window and will not reproduce these races. objectui#8664's first repro leg landed on disk and did not redden for exactly this reason and was reported as fired-but-negative; PR #8689 used 50ms.⚠️ Watch for the quiet failure mode. On objectui#8688 the site CI observed threw aTypeError; the one nobody had observed degraded toundefined === undefinedand passed. Assert concrete distinguishable values, ⛔ never an identity comparison both sides can satisfy withundefined.⚠️ Adjacent work — different populations, do not merge them- objectui#8690 is in flight right now (branch
claude/issue-8690-recorder-wait-audit): nine sites where awaitFornames one recorder array and the read is of another. ⭐ A different population — the intersection with this card's eleven is empty. It touchesplugin-charts/ObjectChart.optionColors,plugin-dashboard/DatasetWidget.relabel,plugin-list/*andplugin-tree/ObjectTree.settledSchemaKeying-6481. ⛔ Different files from yours — keep it that way, and if you find yourself editing one of them, stop and report. - objectui#8534 (kanban mirrored state) and objectui#8666 (
ObjectTree'sexpandedmirror = the component-side root cause) are the same family at the component layer. ⛔ Do not fix a component here; if your diagnosis says the component is at fault, that is a finding to report.
Verification standard
- Verify by CONTENT, never by exit code or sha.
⚠️ An assertion never observed to fail has not been tested — the two vacuous files are the proof that this is not a slogan.- Ask of every pin: "Would an implementation strictly worse than the bug pass this?"
⚠️ For a refusal arm, the implementation strictly worse than the bug is "render nothing, ever" — it satisfies every absence assertion. - Ablation: mutate a READ SITE (never the pin), from a committed tree,
trapon EXIT/INT/TERM with absolute paths, proving the mutation on disk in both directions (anchor counts ANDgit hash-objectvs the HEAD blob) plus a line-total gate; restore by state (git diff HEADempty;git checkout HEAD -- ABSOLUTE_PATH, never the bare form). A void leg is VOID, not green; a leg that lands but does not discriminate is NEGATIVE, not void — report it as negative. - LEG D: per-test classification from vitest's JSON reporter, ⛔ never the text reporter. Count death strings separately.
- Run vitest from the repo root with paths — guard objectui#3378 refuses

Contract review — accepted. PR #8707 is out of draft and armed.
⚠️ And this card, which I filed, was half wrong.⭐ The correction: I read wait EXPRESSIONS, not the lines above them
I nominated two files as vacuous in the refusal direction. One was.
The card's characterisations are readings of wait expressions. Probed at the component, the pivot's arm already carries its completion anchor two lines above the wait the card quotes —
await find.mock.results[0].value. Eight of the nine DOM family files carry that idiom; plugin-gantt had ZERO occurrences, and that single omission is what made it the one measurably vacuous file.⇒ my sweep tabulated "shared wait" per file and drew a conclusion about gating. The gate was two lines up, in eight of nine cases, and I never looked.
plugin-dashboard/ObjectPivotTableis not vacuous and was correctly left alone — which, on a card whose whole thesis is "a wait keyed on a signal that does not gate the read", is a fitting way to be wrong.And the falsification was forced, not argued: ablation C disabled both the records arm and the loading skeleton, proven on disk, and the refusal arm still reddened ⇒ the skeleton is not the anchor either. Then the settle line was isolated in a probe — present at 300ms it reads 2 and FAILS (discriminates); removed at 50ms it reads 0 while the component drew 2 (PASSES, vacuous). That is the anchor, and it is present.
⭐⭐ The gantt repair, and a LEG 1 that needed no mutation at all
LEG 1 for gantt sink 2 needed no bug reintroduction: with the LIVE
dataenvelope and the quick-filter domain answering one macrotask after the rows,expect(offersUnloadedProject(view)).toBe(false)PASSED while the same mount settled tooffered=[p1,p2,p3]— it readoffered=[p1]and called that a refusal.Vacuity demonstrated on the shipped component, on the real envelope, with nothing mutated. The pin was not fragile; it was answering a different question than its name, and the component's own settled state is the counter-example. That is as strong as this evidence gets.
And sink 1 was reported honestly as a spurious RED rather than a silent pass:
gantt-viewrenders only below theif (loading)early return, so under a forced delay the read threw instead of passing. Two sinks in one file with two different failure modes, both named.⚠️ Ablation B is the one I want on the record: "return nothing, ever" took gantt sink 2's refusal arm from PASSED to FAILED ⇒ it no longer accepts the implementation strictly worse than the bug. Sink 1 still reads 0 there — and that is stated as the whole family's documented design, all nine files including the already-repairedplugin-tree, rather than claimed as fixed. Declining to claim a fix you did not make is the harder half.⭐ My plugin-charts hypothesis was tested and refuted
I wrote into the dispatch: "
plugin-chartsdoes have a lazy boundary and is the closest kin to kanban — that is a hypothesis to test, ⛔ not a conclusion."It does NOT hold:
React.lazylives inChartRenderer.tsx, which that pinvi.mocks away, so the pin never crosses the lazy boundary — same shape of finding as tree-vs-kanban in PR #8664.⇒ the third time this family has produced "the neighbouring mechanism does not transfer", and the third time checking is what caught it. A dispatch that had asserted the kinship instead of flagging it would have produced a fix for a boundary the test never reaches.
Two component-level notes that belong on this card
plugin-map's wait is the only absence-shaped one, and at 0ms itsLoading map…panel is never observed at all ⇒ the wait is satisfied with no transition having occurred. It holds only becausesetLoading(false)andsetDatacommit together —⚠️ which nothing pins. An unasserted precondition holding a pin up is the same shape as the rest of this family, one layer down.plugin-timeline'sdata-item-countnot-null check is INERT —getByTestIdthrowing insidewaitForis what actually gates it. The half of the condition that looks load-bearing does nothing.
Both correctly reported here rather than split off: they are diagnoses of files this card names.
The void legs, and the dedup channel
Two VOID legs, reported as void and rebuilt before any conclusion: a first
plugin-mapprobe omitted the pin'sreact-map-gl/maplibremock and measured nothing (TypeErrorfrom real maplibre); two early probe passes leaked containers across runs (marker counts accumulating 2, 4, 6, 8). ⭐ The second is worth remembering — an accumulating count reads like a real measurement and is the kind of artifact that gets published.And the dedup channel is declared precisely: the REST search endpoint answered 403 for all three queries including the control, so it fell back to one targeted MCP
search_issues, which returned 4 hits — not a false zero — and none matching. A fallback whose control fired is a reading; the 403 on the control is what makes saying so meaningful.objectui#8708 filed for a genuinely different class:
ObjectChart's site-2 refusal asserts.not.toBe('Apollo'), a shapeString(undefined)satisfies, so it passes for a resolver that stopped resolving anything. ⭐ Assertion strength, not wait anchoring — correctly kept out of this card.Card state
⇒ objectui#8665's "seven exposed siblings" is now: one repaired, one falsified, five diagnosed and sound-by-the-settle-line-idiom, plus two named component-level gaps. The card's list was a usable pointer and a bad claim — the same verdict objectui#8690's census earned tonight, from the same cause: a tabulation of one expression read as a statement about behaviour.
I filed both. The lesson is mine to carry:
⚠️ a sweep that records what a line says is not a sweep of what the code does, and every time this queue has confused the two today it has cost a dev a full run to undo.

The family
contractEnvelope-6839is 11 files. Two have no DOM (core/extract-records,react/nonGridRowCeiling) and are not in scope. Of the nine DOM files:⭐ Two are ALREADY VACUOUS today — independent of any flake
These are not "at risk of a future race". Their refusal arms cannot fail for the right reason now:
plugin-dashboard/src/__tests__/ObjectPivotTable.contractEnvelope-6839.test.tsx— waits onqueryByTestId('pivot')and the refusal arm expects 0 on that same node. ⇒ "drawn empty" and "drawn before the data arrived" are one reading. The arm cannot distinguish the two states it exists to distinguish.plugin-gantt/src/ObjectGantt.contractEnvelope-6839.test.tsx— the inverse gap.

Each file needs its own component-level probe.⭐ A repeat-run sweep is too weak an instrument to clear these. PR #8664 ran all nine DOM files × 5 loaded iterations for 0 failures — and reported that with its power rather than as a clean bill: the pre-fix tree file's own observed rate was ~1 in 12, and 5 runs miss an 8%-per-run flake about two thirds of the time. ⇒ ⛔ Do not treat a green batch as evidence a sibling is fine; the two vacuous ones above would pass such a sweep forever.
