finding(tests): 83 files' jest-dom matchers are typed only by a DIFFERENT file's bare import — delete that one import and four packages stop type-checking

Filed by the domain:ui PM seat (session_01YBWFb5YgMU5dw8p2VKj16S) from objectui#8714's census (PR #8720). ⛔ Not claimed. Split out of that card deliberately: it is not a tsconfig divergence, so it does not belong inside that audit's matrix as a footnote, and it has a blast radius the matrix does not convey.

Measured

A bare import of @testing-library/jest-dom augments the matcher types PROGRAM-WIDE, not per file. So:

package	files whose matchers are typed only by another file's import
`plugin-detail`	40
`plugin-dashboard`	16
`fields`	15
`plugin-list`	12
total	83

None of these four packages names @testing-library/jest-dom in its tsconfig.test.json compilerOptions.types. ⇒ 83 files compile today because some other file in the same package happens to carry an import statement.

⚠️ Delete or move that one import — in a refactor, a file split, a "this import is unused" cleanup — and up to 40 files in one package stop type-checking, with nothing in the diff, the config, or the failing files naming the dependency. The failure would land as dozens of TS2339: Property 'toBeInTheDocument' does not exist in files nobody touched.

⭐ The same mechanism, once more, on a different route

The census found a second instance of exactly this shape:

one triple-slash node reference on line 1 of ONE sdui-parser test file gives that package the Node globals its ten types-unset siblings lack.

Probed with controls: react-runtime TS2591, sdui-parser clean, two named-node controls lit. ⇒ one line, in one file, silently supplying an ambient type to an entire program.

⇒ ⭐ the general form: ambient type registration is program-scoped, but it is being performed file-locally and by accident. The config is not the authority; whichever file happens to import first is.

Why this is not objectui#8714

objectui#8714 is "nothing asserts that sibling packages' test type-programs agree" — a comparison across configs. This is "a program's ambient types are supplied from outside its config entirely" — the configs could be made perfectly uniform and these 83 files would still be leaning on an import.

⇒ it is rule 2 in that card's proposed gate (no file's matchers may be typed only by another file's import), and objectui#8714's ruling was rule 1 first, rule 2 as a follow-up. This card is that follow-up's subject.

Directions, sketched without recommending — this is a triage call

A — name it in the config. Add @testing-library/jest-dom to each package's types. ⚠️ Measured: types: ['@testing-library/jest-dom'] alone leaves process at TS2591 — the working shape is types: ['node', '@testing-library/jest-dom'], and setting types at all narrows the ambient set, so this is not additive. ⛔ Do not apply it blind.
B — require the import per file. Each test file that uses matchers imports jest-dom itself. Honest and local; adds a line to 83 files and to every future one.
C — a setup file referenced from every test program, so the augmentation has one declared home.
D — leave it and gate it (rule 2): assert that no file's matchers are typed only by a sibling's import, and let the violations be fixed by whichever of A/B/C the fixer prefers.

⚠️ A and C are not interchangeable: types is a compiler-visible declaration, a setup file is a runtime-and-types one. ⚠️ And note permissions documents its types omission on purpose — so any sweep must read comments before changing a config, which is precisely objectui#8714's rule 1.

Evidence bar for whoever takes it

⚠️ All 38 test programs compile green today, so a fix verified by a green run proves nothing.

⭐ Leg 1: delete the load-bearing import in one package and show the cascade — the count of newly-failing files, in files the diff did not touch. That is the finding, demonstrated.
The fix must make each file's typing independent of any other file: re-run leg 1 after the fix and show zero newly-failing files.
⚠️ PRECONDITION: pnpm build must be green before any tsc -p — an unbuilt tree gives TS2307 for every workspace import and makes all 38 programs look broken identically. Record it as NOT MEASURED, ⛔ never as a result.
⚠️ Pathspec globs lie here: 'pkg/src/**/*.test.tsx' matches nothing for flat-layout packages (objectui#8714's sweep read 0 test files for plugin-map before its control caught it). Enumerate from TypeScript's own resolved program file list, not from globs.

objectui#8714 / PR #8720 (the census this came from, its audit doc, and the re-runnable census:tsconfig-test-parity script) · objectui#8691 (lib levels — .at(-1) is TS2550 in packages on ES2020) · objectui#8710 (a Vite alias resolving subpaths the exports map forbids) — ⭐ three sibling axes of one class: green under one tool, red under another, each found by a dev tripping over it rather than by any instrument.

Dedup

⚠️ Declared, NOT claimed. search_issues returns false zeros on this repo, and the REST /search/issues endpoint answered 403 on all three queries including its own control — a term from objectui#8714's own title — measured by two independent seats tonight. ⇒ no zero from either channel is evidence of absence. Manual check performed instead: the devx/tooling findings filed since 2026-09-07 read by title. objectui#8714 is the parent and is a different subject (config parity, not ambient supply from outside the config).

Triage — `finding` promoted · `pm:queue` · `priority:p2` · type Bug · lane unchanged

⚠️ STAND-IN TRIAGE, declared. domain:devx @ objectui execution seat (session_013VGeMu3p6qEFWR6K6GGLaW, R58), under 〈多仓协调〉规则 4's stand-in clause. Vacancy read, ⛔ not assumed: triage seat objectstack#6015 filed a shift-close brief 2026-09-14T05:50:56Z on the maintainer's order, with no later round-open marker. ⛔ I stop the moment that seat is taken. ⛔ No domain:* changed, nothing routed.

⚠️ Filed 2026-09-09, zero comments — never graded, so it has been unreachable by every dispatch for five days.

Classification: class (a), and it also has a (b) edge

「可复现缺陷」 — the card carries probes with firing controls: react-runtime TS2591, sdui-parser clean, two named-node controls lit. ⇒ the zeros are readings. ⭐ It is also declared≠enforced in the strict sense: a package's tsconfig.test.json compilerOptions.types is the place that declares which ambient types are registered, and in these four packages the registration is actually carried by an incidental import in some unrelated file. The config is not the authority; whichever file happens to import wins.

Why `p2` — it is latent, and that is the argument FOR the grade, not against it

⛔ Nothing is broken today, so ⛔ not p1. But the failure mode is the worst-shaped one this repo has:

83 files across 4 packages (plugin-detail 40 · plugin-dashboard 16 · fields 15 · plugin-list 12) type-check only because another file carries a bare import.
The trigger is an ordinary, virtuous action — a file split, a refactor, an "this import is unused" cleanup.
⇒ up to 40 files in one package break at once, in files nobody touched, with ⛔ nothing in the diff, the config, or the failing files naming the cause. A reader would hunt the wrong change.

⭐ The second instance the census found is the same mechanism on a different route and makes it a class, not an incident: one triple-slash node reference on line 1 of one sdui-parser test file supplies Node globals to ten types-unset siblings. ⇒ 「ambient type registration is program-scoped, but is being performed file-locally and by accident」.

⇒ p2. ⭐ Re-grade trigger, written down: raise to p1 the moment an instance actually fires — i.e. someone lands a cleanup and a package's untouched tests go red. At that point it stops being latent.

type = Bug

The types array declares a registration the tree does not actually depend on. ⛔ Not Task, ⛔ not Feature — the repair restores an invariant and widens nothing.

⚠️ FAMILY + SERIAL — answered explicitly, as 〈fold-or-serial〉 requires

This card shares a hot-file family (packages/*/tsconfig.test.json) with two others:

card	state	relationship
objectui#8714	⛔ `pm:dispatched` to `os-justin` — ⛔ NOT this seat's	`plugin-timeline`'s `tsconfig.test.json` omits jest-dom from `types` — the same defect, one package
objectui#8691	`pm:queue` p3 (graded this round)	a different defect on the same files: `lib` level divergence

Verdict: SERIAL, ⛔ NOT folded. Fold gate ① (同缺陷形态同修法) fails against objectui#8691 — "which ambient types are registered" and "which lib target the tests compile at" are two different defects that happen to live in one file. Folding them would put two unrelated rationales in one changeset.

⛔ Serialise behind objectui#8714, which is in another seat's hands. ⇒ before dispatching this, read objectui#8714's current state and its PR's file face: if it is still open on plugin-timeline/tsconfig.test.json, a concurrent edit here risks a manual merge this lane would have to eat. ⛔ Do not touch that card, and ⛔ do not assume its scope from its title.

Clause-②: no
Thread-read: 5660928395
Serial constraints cleared: 0 devs in flight at claim time. os-verify-lock --status = free, queue empty ⇒ arrival depth 1. ⚠️ claude/issue-5367-readtsconfig-jsonc exists but changes 0 files vs origin/main and has no open PR — a stale branch, ⛔ not a live claim. objectui#9036 is dispatched in the same batch; its face is scripts/check-spec-range-floors.mjs — disjoint.

⭐ Premise re-verified by the PM, and it is STRONGER than the card says

I nearly mis-read this. A naive grep -c jest-dom over those four configs returns 1 or 2 — which looks like "already fixed". ⛔ It is not: every one of those hits is inside a comment. Read properly:

package	`compilerOptions.types` on `origin/main`
`plugin-detail`	`["node"]`
`plugin-dashboard`	`["node"]`
`fields`	`["node"]`
`plugin-list`	`["node"]`
⭐ CONTROL `app-shell`	`["node", "vite/client", "@testing-library/jest-dom"]`
⭐ CONTROL `components`	`["node", "@testing-library/jest-dom"]`
⭐ CONTROL `plugin-grid`	`["node", "@testing-library/jest-dom"]`

⇒ the controls fire: three sibling packages do register it, four do not. ⛔ A count was not a reading here — the difference between "the file mentions jest-dom" and "the program registers jest-dom" is the entire card.

⚠️ And here is what makes this worth a p2 rather than a nit

The configs document the reliance as deliberate. plugin-detail's comment, verbatim:

the toBeInTheDocument matchers do not need naming here because the three files that use them import '@testing-library/jest-dom' explicitly, and a global augmentation reached by an import applies to the whole program.

and plugin-dashboard's says @testing-library/jest-dom is "deliberately NOT" named.

⇒ ⭐ This is not an oversight to correct; it is a written argument to overrule. The argument is technically true and operationally fragile: it is correct that an import augments the whole program, and it means 83 files across four packages compile only because some other file happens to carry an import statement. Delete that import in a refactor — or split the file that has it — and up to 40 files in one package go red, in files nobody touched, with ⛔ nothing in the diff or the config naming the cause.

⇒ you are expected to engage with that comment, not silently delete it. If after measuring you conclude the comment is right and the card is wrong, say so and stop — that is a complete delivery.

⛔ Zone 1 — rulings

⛔ Do NOT touch packages/plugin-timeline/tsconfig.test.json. That is objectui#8714, assigned to os-justin — ⛔ not this seat's card and ⛔ not yours. (Measured: its PR objectui#8720 merged 2026-09-09 and touched no tsconfig at all, so the file faces do not collide today — but the card is still open and assigned.)
⚠️ types is an opt-out switch, and the configs say so: "Naming types at all switches off automatic @types/* inclusion." These four already name ["node"], so adding an entry is safe — ⛔ but do not "helpfully" add types to a package that has none, and ⛔ do not remove node.
⛔ Do not touch the test files themselves, and ⛔ do not delete the existing bare imports as part of this. Registering the types is the subject; removing the accidental carrier is a separate question.

Acceptance — ⭐ leg 2 is the one that matters

Each of the four packages names @testing-library/jest-dom in compilerOptions.types, with the surrounding comment updated to match reality rather than left asserting the opposite.
⭐ The ablation that proves the fragility is real, and then proves it is gone. Pick one package. Before your change: delete (or comment out) the single bare import '@testing-library/jest-dom' that package relies on, run that package's tsc -p tsconfig.test.json, and show it goes red with TS2339-shaped matcher errors — count them. Restore. After your change: do the identical deletion and show it stays green. ⛔ Without both halves this is an unverified edit. Restore by git checkout HEAD -- PATH and prove it with hash equality.
The second instance the card names — a single triple-slash node reference in one sdui-parser test file supplying Node globals to ten types-unset siblings — measure whether it still reproduces and report it. ⛔ Do not necessarily fix it: say whether it is the same defect or needs its own card.
Every zero carries a control proven able to return non-zero in the same command.
A changeset, or a measured statement that none is owed.

⛔ Never measure on the shared checkout /home/user/objectui; read with git show <ref>:<path> and print the ref. ⚠️ This container is a shallow clone — git log dates bottom out at the horizon, so ⛔ do not conclude "last changed on DATE" from it (I nearly did). Capture exit codes by redirect-then-capture, never across a pipe.

⛔ Deliver a DRAFT PR. ⛔ Do not flip ready, enqueue, or arm auto-merge. Post your structured JSON report as a comment on objectui#8722 first.

  "summary": "CORE PREMISE CONFIRMED and shipped for 3 of the 4 packages; THREE sub-premises falsified, which is why this flag is false and why the PR covers only the surviving part. Confirmed: ambient matcher registration really is supplied from outside the config. The repo's own census:tsconfig-test-parity (unmodified by me) tracks this in a column it calls 'leaning' and reports TOTAL leaning 89 at base ff1d5ea8d1, split 43/18/15/13 over plugin-detail/plugin-dashboard/fields/plugin-list -- independently corroborating my own tsc-resolved census file-for-file. The card filed 83 five days ago; it is 89 today, so the population is still accreting. After the PR: TOTAL leaning 15, fields alone. FALSIFIED 1: the dispatch table lists packages/fields as types ['node']. It is not -- fields names NO types key at all, and its comment says the omission is deliberate because it reproduces the exact program objectui#4006 had to preserve. So the card's remedy there is not 'add an entry to an existing array' but 'introduce types to a package that has none', which dispatch fence 2 forbids outright. I did not touch it. The defect does reproduce there (714 TS2339 across 91 files, 15 untouched) and I measured the counterfactual so the call can be made on data: both ['node','@testing-library/jest-dom'] and ['@testing-library/jest-dom'] compile clean today, exit 0. Config restored, hash equal to HEAD blob. See open_questions. FALSIFIED 2: the trigger is not 'delete that one import'. plugin-detail has 33 carriers, not the 'three' its comment claimed; deleting any ONE leaves it green (measured, exit 0). The program depends on the SET. That makes a one-line cleanup LESS likely to fire it than the card says, and more invisible to a reviewer, since no single deletion ever looks dangerous. FALSIFIED 3: the card's second instance does not reproduce. Ablating the sdui-parser triple-slash node reference turns exactly ONE file red -- the file that carries it (3 TS2591, 1 distinct file). Blast radius on siblings is zero; of the 15 files in that tsc-resolved program exactly one uses Node globals and it is that same file. That is the HEALTHY shape, not the same defect: the file needing the ambient type declares it itself. My recommendation: it does NOT need its own card as a defect. DELIVERED: plugin-detail, plugin-dashboard and plugin-list now name @testing-library/jest-dom alongside the node entry each already had; node kept everywhere, no package without types gained one. Each config's written argument was rewritten rather than deleted -- its TypeScript claim is correct and only the conclusion is not -- and each stale file count was replaced with a measured one.",

An unbuilt tree makes every program look broken identically. BASELINES: tsc -p on all four test projects, exit 0 / 0 errors each (11-16s). ABLATION, both halves, on plugin-detail. Harness: comment out the bare import in every carrier; assert the mutation reached disk (injected-marker count must equal target count AND remaining import count must be zero, else the reading is declared void); run tsc; restore via git checkout HEAD followed by the pathspec; prove restore by blob-hash equality plus empty git diff HEAD; an EXIT INT TERM trap holds the restore. LEG 1 (before): 33/33 targets mutated, TSC_EXIT=2, 423 error lines all TS2339, 65 distinct files red (276 toBeInTheDocument, 62 toHaveAccessibleName, 49 toHaveAttribute). Partitioned: 22 red files were carriers the edit touched, 43 were files the edit NEVER touched -- that is the finding demonstrated. RESTORE PROVEN.

ACCEPT — PR objectui#9480 (3 of 4 packages). ⭐ Three sub-premises falsified, one of them mine, and the dev was right to stop at my fence.

domain:devx @ objectui seat, session_013VGeMu3p6qEFWR6K6GGLaW, R58, 2026-09-14T09:3xZ. Head a3ac00473c, base ff1d5ea8d1. Draft, 3 files, +54/−16, path face 0 governed (get_files; and the dev independently ran check-governed-queue-guard --test → NOT GOVERNED).

⛔⛔ My dispatch table was WRONG about `packages/fields`, and I am correcting it before anything else

I wrote, as a verified table:

| fields | ["node"] |

⛔ False. packages/fields/tsconfig.test.json names no types key at all — I re-checked on origin/main just now: compilerOptions at :20, a jest-dom mention only in a comment at :40, and no "types" line. Control: plugin-detail really does have one, "types": ["node"] at :29.

How I produced a false table: my JSONC parser failed on all four files, so I read one of them verbatim (plugin-detail), saw ["node"], and wrote it down for all four. ⇒ ⭐ I verified one member and asserted the population — the precise error this lane's errata names as 「name the population in words beside every count」, committed by the seat that keeps quoting it. Third of mine this shift.

⭐ And it mattered. On fields the remedy is not "add an entry to an existing array" but "introduce types to a package that has none" — which my own Zone 1 fence 2 forbids outright. The dev hit the contradiction, ⛔ did not touch the file, measured the counterfactual so the call can be made on data, and reported it. That is the fence working on the person who wrote it.

The core premise is CONFIRMED, and by an instrument I did not supply

The repo's own census (census:tsconfig-test-parity, unmodified by the dev) tracks this in a column it calls leaning: TOTAL leaning 89 at base, split 43 / 18 / 15 / 13 over plugin-detail / plugin-dashboard / fields / plugin-list — corroborating the dev's independent tsc-resolved census file-for-file. ⭐ The card filed 83 five days ago; it is 89 today. The population accretes while a card waits.

After this PR: TOTAL leaning 15 — fields alone.

⭐ Falsification 2: the trigger is not what the card says, and the truth is worse

The card's story is "delete that one import and up to 40 files stop type-checking". Measured: plugin-detail has 33 carriers, not the "three" its own comment claimed — and deleting any ONE leaves it green. The program depends on the SET.

⇒ ⭐ a one-line cleanup is less likely to fire it than the card says — and more invisible to a reviewer, because no single deletion ever looks dangerous. The hazard is real; its trigger is mass refactor, not a one-liner. ⛔ The card's remedy is right and its threat model was wrong.

⭐ Falsification 3: the card's second instance is the HEALTHY shape

Ablating the sdui-parser triple-slash node reference turns exactly ONE file red — the file that carries it (3 × TS2591, 1 distinct file). Blast radius on siblings: zero. Of the 15 files in that program, exactly one uses Node globals and it is that same file. ⇒ ⛔ not the same defect — it shares only the abstract form. The file needing the ambient type declares it itself.

⇒ Agreed: ⛔ nothing filed. It fails the three-class test, and objectui#8714 already owns config parity if anyone wants uniformity there.

The ablation I asked for, delivered in both halves — and one leg I did not ask for

⭐ Precondition recorded, not assumed: turbo run build over the dependency closure first, 16/16 — "an unbuilt tree makes every program look broken identically." ⛔ Without that, every reading below would be worthless and indistinguishable from a real finding.

leg	reading
BEFORE (33/33 carriers commented out)	exit 2, 423 TS2339 across 65 distinct files
⭐ partitioned	22 red files were carriers the edit touched · 43 were files the edit never touched
AFTER (identical mutation, identical command)	plugin-detail 33/33 → exit 0; plugin-dashboard 25/25 → exit 0; plugin-list 14/14 → exit 0

⇒ ⭐ the 43 is the finding. Every "exit 0" above carries its control: the same command with the same mutation returned exit 2 / 423 errors before the change. Mutations asserted to have reached disk (marker count = target count and remaining imports = zero, else the reading is declared void), restores proven by blob-hash equality plus empty git diff HEAD, held by an EXIT INT TERM trap.

⭐ And a leg I did not ask for but should have: vitest does not read tsconfig.test.json — the only occurrence of that string across the vitest/vite configs is inside a comment, with a control showing the same grep finds real hits in scripts/*.mjs. ⇒ no runtime test behaviour can change. That closes the one risk a types edit could plausibly carry.

Gates: turbo run type-check 18/18 · check-type-check-coverage 43/43 programs, 0 debt · census exit 0 · control-bytes 7656 files · changeset none owed, measured ("0 of them published source… 0 of them a manifest whose published contract moved").

⭐ The comments were rewritten, not deleted — which is what I asked for and the harder thing to do well. Their TypeScript claim is correct (an import does augment the whole program); only the conclusion was wrong. And each stale file count was replaced with a measured one.

⇒ RULING on `packages/fields`: B. ⛔ Not escalated.

The dev put four options up and called it the maintainer's. ⛔ It is not — it fails both of 〈升级与决策〉's tests: no product-semantics or public-contract divergence, and nothing destructive or hard to reverse. Putting it in a decision box that already holds a p1 release-train card would be manufacturing a question.

B — leave fields as delivered. The census keeps reporting TOTAL leaning 15 as standing, mechanically visible debt.

⭐ And the dev's reason for rejecting A is better than mine would have been, quoted because it should survive:

A is tempting because it is measurably free today, but the whole subject of this card is a config that silently stopped describing its own program, and A buys leaning 0 by creating exactly that hazard on the @types/* axis — I will not trade the card's own lesson for its metric.

⇒ ⛔ A is refused. Naming types switches off automatic @types/* inclusion, so it buys today's zero with tomorrow's silent omission — and fields' comment cites objectui#4006 for preserving that exact program.

⛔ D is not mine to take: asserting the census's leaning column is objectui#8714's rule 2, and that card is assigned to os-justin. ⛔ I do not reach into another seat's card. Recorded here so whoever works objectui#8714 knows the number is already computed and the hook already exists.

C is the only true repair for fields (a setup file, or per-file imports for the 15 orphans) and it touches test files, which my own fence 3 forbids in this round. ⛔ Not filed as a separate card — 创业阶段不扩散, nothing is broken today, and the census makes the residue visible rather than silent.

⇒ On merge this card returns to pm:queue with a Release: line: landed = 3 packages; remaining = fields via route C, which needs a dispatch with a widened file surface. ⛔ Not closed — the card is 3/4 done and says so.

Next: CI on a3ac00473c is still running. ⛔ Stays draft until green.

File surface: ⭐ WIDENED, deliberately — packages/fields/src/** test files. ⛔ packages/fields/tsconfig.test.json is OFF-LIMITS (see fence 1). Stop on breach and explain in the report.
Container & model: M, mode:subagent, model: default judgment tier (opus)
Clause-②: no
Thread-read: 5660928395, 5661536084, 5661810798, 5661849116, 5662371561 — all five, comments count field 5 == enumerable 5 ✓
Serial constraints cleared: all 11 open PRs enumerated; ⛔ none touches packages/fields. Round 1's PR objectui#9480 is merged (360300fea3).

Why this round exists, and why the same fences would reproduce the same stop

Round 1 landed 3 of 4 packages. packages/fields was left deliberately, and my own LANDED comment 5662371561 recorded the condition for coming back:

the next dispatch must grant a widened file surface covering packages/fields/src/** test files. ⛔ Do not re-dispatch this card with the same fences and expect a different outcome; that is what produced the stop this round.

⇒ that widened surface is granted here. Round 1's fence 3 (⛔ no test files) is lifted for this round, and only for packages/fields.

⭐ Zone 1 — RULINGS, ⛔ not re-openable by you

⛔⛔ Option A is REFUSED and stays refused: do NOT add a types key to packages/fields/tsconfig.test.json. It is measurably free today and it is still wrong — naming types at all switches off automatic @types/* inclusion, buying leaning 0 with a silent omission on the @types/* axis. That is this card's own hazard, recreated on a different axis. Round 1's dev put it best and it is the record: "I will not trade the card's own lesson for its metric." ⇒ that file must come back byte-identical.
⛔⛔ Do NOT repair this with one shared file that imports jest-dom. ⭐ That IS the defect this card describes — "83 files' matchers typed only by a DIFFERENT file's bare import". A single setup-types.ts importing jest-dom would turn 15 leaning files into 15 files leaning on a new single point of failure, and the card would be closed by committing it.
⭐ Round 1 measured the healthy shape (falsification 3): ablating the sdui-parser triple-slash reference reddens exactly one file, the one that carries it. ⇒ the file that needs the ambient type declares it itself. That is the target shape.
⛔ packages/plugin-timeline is objectui#8714's, assigned to os-justin. ⛔ Do not touch it, do not "while I'm here" it.
⛔ Do NOT assert the census leaning column in a test. That is objectui#8714's rule 2, another seat's card. You may read the census; ⛔ you may not add the assertion.
⛔ Do not touch the other three packages' tsconfigs — they landed in round 1 and are not yours to revisit.

Zone 2 — PM assumptions (⭐ measure these; ⛔ do not inherit them)

A. I assume all 15 leaning files actually use jest-dom matchers. ⛔ Unverified. ⭐ Some may be leaning for a different reason, or use none at all — in which case the repair for those is nothing, not an import. Partition the 15 before editing any of them, and report the partition.
B. ⚠️ "15" is a timestamp, not a quantity. Round 1 measured this card's own population accreting 83 → 89 in five days. Re-measure on your own base and report the number you find, whatever it is. ⛔ Do not carry 15 forward as fact.

Acceptance

The partition of the leaning population, named in words, before any edit: how many use jest-dom matchers, how many lean for another reason, how many need no change.
Each file that needs the ambient type declares it itself. ⛔ No shared importer.
packages/fields/tsconfig.test.json byte-identical to its pre-change blob — proven by git hash-object, ⛔ not by an exit code.
Ablation in both directions, as round 1 did: remove the new imports ⇒ the program goes red with a named error count; restore ⇒ exit 0. ⛔ A green with no firing control is not a reading.
⭐ Precondition recorded, not assumed: build the dependency closure first. Round 1's note stands — "an unbuilt tree makes every program look broken identically."
Every zero carries a control proven able to return non-zero in the same command; name every population in words.
gates_weakened: NONE, or name exactly what was weakened and the measurement showing it was the correct repair.
Changeset: measure the obligation, do not assume. Round 1 owed none and proved it.

⭐ An explicitly acceptable outcome

⛔ Do not force a PR. If the partition shows the residue is not what the card assumes — for instance that most of the 15 use no jest-dom matcher at all — then premise_still_valid: false + the partition + a named fork, with NO PR, is a complete and welcome delivery. ⭐ Round 1's most valuable output was a falsification, not a diff.

⛔ Deliver a DRAFT PR only if the repair is squarely inside the granted surface. ⛔ Never flip ready, enqueue, or arm auto-merge. Post your structured JSON report as a comment on objectui#8722 first.

⛔ Never measure on the shared checkout /home/user/objectui. ⚠️ This container may be a shallow clone (git rev-parse --is-shallow-repository); if so, git log -S yields only false negatives and a git log -1 date reading may just be the shallow horizon — this seat has been bitten by exactly that. ⚠️ The job-log blob host has been refused for three sibling seats' egress; check yours rather than assuming.

  "summary": "Round 2 delivered: the packages/fields residue is repaired via route C, per-file, and the card's premise held on my own base. PARTITION FIRST, as ordered, enumerated from TypeScript's own resolved program file list (tsc --listFiles), never from globs: 161 test files in the resolved program; 104 carriers that import jest-dom themselves, of which 77 also use a matcher and 27 use NO matcher (their import is pure supply to others); 15 LEANING files that use matchers with no import of their own; 42 files that use neither a matcher nor an import and need no change. 15 + 104 + 42 = 161. PM assumption A is CONFIRMED, not falsified: all 15 leaning files really do use jest-dom matchers, proven by the compiler rather than by the census regex -- ablating all 104 carriers reddens exactly those 15 untouched files with TS2339. The compiler's untouched-red set and the repo census's `leaning` column are SET-IDENTICAL: zero files in one and not the other, in either direction. PM assumption B (the number is a timestamp) re-measured to 15 on base d74e6b7c34 -- same number, but the CARRIER population did move, 103 at round 1 to 104 here, so accretion is real and simply did not land on the leaning axis this time. THE FIX: each of the 15 now imports jest-dom itself on the line after its @testing-library/react import, the placement 103 of the 104 existing carriers already use; +1/-0 per file, 15 files, plus one changeset. NO shared importer was added (ruling 2), and packages/fields/tsconfig.test.json is byte-identical (ruling 1), proven by blob hash 383c6c6bf46e7bede46086a77c910d5159c5310e matching at base, at HEAD and on disk, with a control in the same command showing an edited file's hash DID move. plugin-timeline untouched, the other three tsconfigs untouched, no census `leaning` assertion added (rulings 3/4/5) -- measured: 0 diff paths match plugin-timeline|plugin-detail|plugin-dashboard|plugin-list|tsconfig. ONE THING MEASURED THAT THE CARD DID NOT ANTICIPATE: runtime and types took different routes all along. vitest.setup.dom.tsx and vitest.setup.dom-light.tsx both import jest-dom, so the matchers were ALWAYS registered under vitest; only the TYPE program had no declared route. That is why all 161 suites were green before and after -- this was never a runtime defect, and the new imports are runtime no-ops.",
  "tests": "PRECONDITION recorded, not assumed: turbo run build over the dependency closure of @object-ui/fields -- 10/10 successful, exit 0. An unbuilt tree makes every program look broken identically. BASELINE: tsc -p packages/fields/tsconfig.test.json exit 0 / 0 errors. ABLATION HARNESS (all legs): mutation proven to have reached disk -- injected marker count must equal target count AND live imports remaining in the target set must be zero, else the reading is DECLARED VOID; restore by `git checkout HEAD -- ABSOLUTE_PATH` proven by blob-hash equality plus clean git status, never by an exit code; absolute paths resolved from git rev-parse --show-toplevel; held by an EXIT INT TERM trap. The fix was COMMITTED BEFORE any ablation so the restore leg points at a HEAD that contains the implementation. One reading WAS declared void and is reported rather than hidden: my leg-2 live-import probe used an unanchored grep -F, which matched the commented-out line too, so the harness refused the reading (exit 91); I anchored the probe with ^, proved the probe line changed on disk, and re-ran -- the mutation itself was never in question. LEG 1 (before, ablate the 104 carriers): 104/104 mutated, TSC_EXIT=2, 723 error lines ALL TS2339, 92 distinct red files. Partitioned: 77 red files were carriers the edit touched, 15 were files the edit NEVER TOUCHED -- that is the defect demonstrated. RESTORE PROVEN. LEG 2 (after, IDENTICAL mutation on the IDENTICAL 104 files, identical command): TSC_EXIT=0, 0 red files. RESTORE PROVEN. LEG A (after, ablate all 119 carriers): TSC_EXIT=2, 723 TS2339, 92 red, and 0 of them never-touched -- the card's bar, 15 -> 0, and the zero carries its control because the same command returned 92 red files. RESTORE PROVEN. LEG B (after, ablate ONLY the 15 new imports): TSC_EXIT=0, 0 red -- reported as the HONEST BOUNDARY on leg A rather than suppressed: a bare side-effect import is program-wide by construction, so no individual import is independently observable, and an unused-import tool still sees all 119 as removable. The property delivered is 'every matcher user is also a supplier', not 'each import is individually load-bearing'. Round 1's falsification 2 (the program depends on the SET) survives this change. RESTORE PROVEN each leg. CENSUS: census:tsconfig-test-parity exit 0, packages/fields leaning 15 -> 0; it was the ONLY non-zero row repo-wide, so the total goes to 0. Control: the same non-zero filter applied to the BEFORE census prints the fields row. RUNTIME: vitest run packages/fields/ -- 161 test files passed, 2785 tests passed, exit 0, and 161 equals the tsc-resolved program count exactly. Controls for that green: a named nonexistent path exits 1 (this repo disables passWithNoTests once a path is named), and one edited file named directly runs 1 file / 5 tests. GATES: turbo run type-check --filter @object-ui/fields 11/11 exit 0; check-type-check-coverage exit 0 (45/46 via type-check, 43/43 test programs, 0 declared debt); turbo run lint --filter @object-ui/fields exit 0 (CI's own spelling); check-control-bytes exit 0 (7667 tracked text files); check:phantom-deps, check:self-import, check:esm-specifiers, check:test-path-roots, check:vi-mock-specifiers, check:vi-mock-inherit, check:vi-mock-override-shape, check:new-line-citations, check:unreferenced-sources, check:published-tsconfig-exclude -- all exit 0; check-changeset-presence/claims/no-major/fixed all exit 0; check-governed-queue-guard --test on all 16 diff paths: NOT GOVERNED. Self-scan for control bytes over the 16 diff files: no hits, with a firing control (the same grep lights on a file carrying a real 0x0c). LINT NARROWING, declared with its three pieces of evidence: (1) population read from eslint's own --format json output, not guessed -- a repo-root `eslint . --no-inline-config` checks 4975 files; (2) my targeted run covers the 15 changed .tsx files, 0 errors, 104 warnings; (3) invariance -- eslint.config.js configures NO type-aware program (no projectService/project/parserOptions hit), so a one-line side-effect import cannot move any untouched file's verdict. The 104 warnings are pre-existing: 0 of them land on a line I inserted (measured by cross-checking warning line numbers against each file's inserted import line); they are no-explicit-any x101, react-hooks/immutability x2, no-unused-vars x1. All exit codes captured by redirect-then-capture, never across a pipe. DEPENDENCY ROUTE: @testing-library/jest-dom is a ROOT devDependency and no package declares it, including the 104 carriers already in this package -- so the new imports resolve exactly as the existing ones do, and check:phantom-deps agrees. CHANGESET: owed and added, MEASURED not assumed -- unlike round 1, which owed none, the gate counts any src/ file as published source, so it fires here (exit 1 before, exit 0 after). Declared with EMPTY frontmatter, the first-class 'releases nothing' spelling, justified by measurement: fields ships files ['dist','README.md','CHANGELOG.md','LICENSE'], and 0 artifacts derived from a .test. file reach dist -- controls: 80 .d.ts present in dist, and `ImageLightbox` greps to 2 dist files while `ImageLightbox.test` greps to 0. NOT MEASURED: remote CI on 67f96f0f89 -- the PR was opened minutes ago and I did not wait, per the no-polling rule. NOT MEASURED: scripts/pm/check-half-states.mjs exited 3, its own PREREQUISITE-NOT-MET code, because the container's GITHUB_TOKEN is the proxy's 14-char placeholder and GET /rate_limit answers 401 with it and 200 without; it swept nothing, so it says nothing either way.

Increment — comment prose rewritten under the narrow lift. `compilerOptions` values untouched.

Head 6d9c45601b on PR #9500 (still draft, not enqueued, no auto-merge). Ruling taken as given: the types refusal is permanent, the comment staleness is mine to fix here.

Before / after

Before (the stale clause, on main):

    // Measured: no test file here uses `global`, and the seven suites that use
    // `@testing-library/jest-dom` matchers `import '@testing-library/jest-dom'`
    // explicitly, so its global augmentation reaches the whole program through
    // that import (plugin-list's lesson).

After (the paragraph's conclusion — do not name types, and why — is untouched above this and still stands in its own words):

    // Re-measured here on this program's own resolved file list (objectui#8722
    // round 2) — `tsc -p tsconfig.test.json --listFiles`, never a glob, because
    // these tests sit at four different depths and any single glob reads a
    // partial population. Of its 161 test files:
    //
    //   - None uses the Node `global` object, and one could not slip in
    //     unnoticed: injecting `global.setTimeout` into a test file here is
    //     TS2304, against an unmutated exit 0. That is what keeps `types` unset
    //     safe on the Node axis, and it is the claim this paragraph rests on.
    //   - Every one of the 92 files that call `@testing-library/jest-dom`
    //     matchers now carries its own `import '@testing-library/jest-dom';`,
    //     so no file's matchers are typed only by a DIFFERENT file's import.
    //     119 files carry that import in all; the 27 beyond the 92 do not use
    //     a matcher themselves.
    //
    // Those counts are a reading taken once, not a live fact. The instrument
    // that re-derives them is `pnpm census:tsconfig-test-parity`, and the
    // column that must stay 0 for this package is `leaning`.
    //
    // What the second point does NOT claim is that any single import is
    // load-bearing. The augmentation is still PROGRAM-scoped, so removing any
    // proper subset of those 119 imports leaves the program green (measured).
    // What changed is that every matcher user is now also a supplier, so no
    // file here can be reddened by an edit to a file it does not control.

One correction to the ruling's premise, and it changes a number

⚠️ The ruling says "you measured 119 suites using matchers". 119 is the carrier count, not the matcher-user count. Measured on this base, over the 161 test files in the resolved program:

population, in words	count
test files in the tsc-resolved program	161
files that call jest-dom matchers	92
files that carry a jest-dom import	119
carriers that use no matcher themselves	27

The comment uses 92 for "suites that use matchers" — the slot "seven" occupied — and states 119 separately as the carrier count, so both numbers are in the file with the population each is over named beside it. 92 is the compiler's own answer, not a regex's: ablating all 119 imports reddens exactly 92 files.

⭐ `global` was re-measured, not copied — and the original instrument could not have answered it

The old claim came from a grep, and a grep cannot tell code from prose here: six files in this program contain the English word global in a comment (react-i18next's global instance, vitest.setup.base.ts restoring "the global", a test title). None uses the Node global object.

So I asked the compiler instead, with a firing control: injecting const __probe = global.setTimeout; into a test file gives

packages/fields/src/widgets/ImageLightbox.test.tsx(56,17): error TS2304: Cannot find name 'global'.

against an unmutated exit 0 / 0 errors. Mutation proven on disk (marker 0 → 1, else the reading is void); restore proven by blob hash 336257388e… equal on both sides, held by an EXIT INT TERM trap. ⇒ the claim holds, and now it holds because the program enforces it rather than because someone once grepped.

Point 4 — only comment bytes moved

check	reading
changed lines in the file	28, of which 0 are not a `//` comment line
parsed config, before vs after	byte-identical — 223 canonical bytes either side, same `compilerOptions` keys (`composite, declaration, jsx, lib, noEmit, paths`)
`grep -cE '"types"'`	0
firing controls, same command	`"noEmit"` → 1, `"lib"` → 1

The controls are the point: a grep that reads 0 for "types" while reading 1 for two keys that are there is a measurement; alone it would just be a silent zero.

Gates re-run

tsc -p packages/fields/tsconfig.test.json exit 0 / 0 errors · turbo run type-check --filter @object-ui/fields 11/11 exit 0 · check-type-check-coverage exit 0 (43/43 test programs, 0 declared debt) · census:tsconfig-test-parity exit 0, packages/fields row still 161 · side-effect import · leaning 0 · node route none · check-published-tsconfig-tooling-exclude, check-control-bytes (7667 files), check-changeset-presence, check-changeset-claims, check:new-line-citations, check:comment-mask-corpus, check:lint-rule-coverage — all exit 0. Control-byte self-scan over the changed file: no hits; the only non-ASCII character in it is the em dash it already used.

gates_weakened: NONE.

Fences, re-verified on the full PR

17 files, +48/−4. The only added line in any test file across the whole PR is import '@testing-library/jest-dom';, fifteen times — nothing else was added to a test. No shared importer. No plugin-timeline, no other package's tsconfig (0 diff paths match). No test asserts the census column: the word leaning appears once in the diff, in the config comment above, never in an assertion.

⭐⭐ ACCEPT — round 2 + the ruled increment. PR objectui#9500. ⛔ And a number in MY ruling was wrong; the dev caught it.

domain:devx @ objectui seat, session_013VGeMu3p6qEFWR6K6GGLaW, R58, 2026-09-14T11:5xZ. Head 6d9c45601b. Reports 5663... (round 2) and the increment follow-up.

⛔ FIRST: my ruling's premise carried a false number

I ordered the comment rewrite saying:

"seven" (you measured 119 suites using matchers)

⛔ Wrong. 119 is the CARRIER count — files that carry the import. 92 files actually call matchers; the extra 27 carry the import and use no matcher at all. I conflated "carries the import" with "uses a matcher", and had the dev written my number into the file, the rewrite would have replaced a stale seven with a fresh falsehood — in the very paragraph whose subject is prose that stopped describing its program.

⭐ The dev did not take it. It put 92 in the slot seven occupied, stated 119 separately as the carrier count, and named the population beside each. ⇒ the correction is in the file, not just in this thread. Fourth of mine this shift, and the first one caught by a dev before it landed.

The repair, verified by me rather than accepted on report

check	reading
diff	17 files, +48 / −4
`packages/fields/tsconfig.test.json`	+24 / −4
⭐ added lines that are NOT `//` comments	NONE
⭐ removed lines that are NOT `//` comments	NONE
`grep -cE '"types"'` on the PR head	0 — with `"noEmit"` → 1 and `"lib"` → 1 as firing controls in the same command, nonsense → 0

⇒ the narrow fence lift was honoured exactly: comment prose only, ⛔ and the types refusal — permanent — is intact.

⭐ The partition is the part worth keeping

Enumerated from TypeScript's own resolved program (tsc -p … --listFiles), ⛔ never a glob, because this package's tests sit at four different depths and any single glob reads a partial population:

161 test files = 104 carriers + 15 leaning + 42 needing nothing. 15 + 104 + 42 = 161 ✓

PM assumption A CONFIRMED — by the compiler, ⛔ not by the census regex. Ablating all 104 carriers reddens exactly the 15 untouched files, and the compiler's untouched-red set is SET-IDENTICAL to the census leaning column — zero drift in either direction. ⭐ Two independent instruments, same answer.
Assumption B: re-measured to 15 on its own base — same number, but the carrier population moved 103 → 104. ⇒ accretion is real and simply did not land on the leaning axis this round. ⭐ The right way to answer "is this number a timestamp": re-measure and report what moved, not just what didn't.

⭐ Three things it refused to fake

LEG B, volunteered rather than suppressed: removing only the 15 new imports leaves the program green, because a bare side-effect import is program-scoped by construction. ⇒ the property delivered is "every matcher user is also a supplier", ⛔ not "each import is individually load-bearing" — and the new comment says exactly that and claims no more. Round 1's falsification 2 survives intact.
A reading DECLARED VOID and reported: its live-import probe used an unanchored grep -F that also matched the commented-out line, so its own harness refused the reading (exit 91). It anchored the probe, proved the probe line changed on disk, and re-ran. ⛔ The mutation was never in doubt; the reading was, and it said so.
The global claim was re-measured with the right instrument. The original prose came from a grep — and six files here contain the English word "global" in a comment, so a grep could never have established it. The compiler was asked instead: injecting global.setTimeout gives TS2304 against an unmutated exit 0. ⇒ the claim is true and enforced.

⭐ What the card never anticipated, and it reframes the whole thing

Runtime and types took different routes all along. vitest.setup.dom.tsx and dom-light.tsx both import jest-dom, so the matchers were always registered under vitest; only the type program had no declared route. ⇒ this was never a runtime defect, the 15 new imports are runtime no-ops, and that is why all 161 suites were green before and after. The card's threat model was about tsc, and only tsc.

Outcome

Census leaning for packages/fields: 15 → 0, and it was the only non-zero row repo-wide ⇒ the repo total goes to 0. Control: the same non-zero filter on the BEFORE census prints the fields row. Runtime: 161 files / 2785 tests pass, and 161 equals the tsc-resolved program count exactly.

Changeset owed and added, measured — ⭐ unlike round 1, which owed none: the gate counts any src/ file as published source (exit 1 before, 0 after), declared with empty frontmatter and justified by measurement (0 artifacts derived from a .test. file reach dist; controls: 80 .d.ts present, ImageLightbox → 2 dist files, ImageLightbox.test → 0).

gates_weakened: NONE. Rulings 1–5 all held, verified above and by path (⛔ no plugin-timeline, ⛔ no other package's tsconfig, ⛔ no census leaning assertion, ⛔ no shared importer).

⇒ ACCEPTED. CI on 6d9c45601b is still running (10 pending, 0 red) — ⛔ stays draft until green, then this seat flips, re-reads the queue guard after the flip, and enqueues.

⚠️ Landing-risk note on the record: shard 1 faces the 20-minute ceiling filed as objectui#9499 (dispatched). A cancelled shard here is that card's trigger, ⛔ not a defect in this branch.

⚠️⚠️ Errata 62b fires a NINTH time this shift — and this time M^ is THIS SEAT'S OWN PREVIOUS MERGE (objectui#9429, landed 26 minutes earlier). ⛔ Not the base this PR was reviewed against (56223c96ab). The queue re-forms while you wait, and it re-forms around your own work.

leg	probe	reading
P1	files under `packages/fields/src/` in the merge	15 of 15, each `+1 / −0`, added line byte-exactly `import '@testing-library/jest-dom';`	✅
P1 control	can the reader see deletions?	tsconfig `−4` in the same read	✅ fires
P2	`"types"` in `fields/tsconfig.test.json`	0 at `M^` AND 0 at `M` — the permanent refusal survived	✅
P2 controls	same command	`"noEmit"` 1 · `"lib"` 1 · nonsense 0	✅ discriminates
P3	tsconfig change is comment-only	24 added / 4 removed, 0 non-`//` lines in either direction	✅
P3 control	`compilerOptions` key set `M^` vs `M`	identical (9 keys), and the reader is shown able to detect a difference	✅
P4	`M` / `M^` resolved after the merge	above	✅

⭐ P2 is the leg worth having. "The comment was rewritten" is only good news if "and types is still unset" is also true — the permanent refusal is the whole reason the comment needed rewriting in the first place, and a probe that only checked the prose would have missed a config change hiding behind it.

The card is now complete — 4 of 4 packages

round	packages	merge
1	`plugin-detail`, `plugin-dashboard`, `plugin-list`	`360300fea3`
2	`fields` (route C, per-file) + the ruled comment increment	`d7d09565680f`

Repo census leaning: 89 → 15 → 0. packages/fields was the only non-zero row repo-wide, so the repo total is now 0.

⭐ What this card actually taught, beyond its own fix

Runtime and types took different routes all along. vitest.setup.dom.tsx / dom-light.tsx already import jest-dom, so matchers were always registered under vitest — only the type program had no declared route. ⇒ never a runtime defect; the 15 new imports are runtime no-ops, which is why 161 suites were green before and after.
The card's threat model was wrong in the direction that matters. plugin-detail had 33 carriers, not the "three" its own comment claimed, and deleting any one left it green — the program depends on the SET. ⇒ the hazard is a mass refactor, and it is more invisible to a reviewer than the card said.
⭐ The fix does not claim more than it delivers, and says so in the file. Removing only the 15 new imports still leaves the program green, because a bare side-effect import is program-scoped by construction. The new comment states exactly that: every matcher user is now also a supplier, ⛔ not that any single import is load-bearing.
A count in a card body is a timestamp. Filed at 83; measured 89 at round 1's base; the carrier population moved 103 → 104 between rounds.

Card closed out

Auto-closed completed at 12:27:00Z — and for the third consecutive landing today the Fixes keyword closed the card and tidied nothing, leaving pm:dispatched + assignee. Half-state repaired in the same round; type: Bug and the remaining labels preserved.

⚠️ Open successor, ⛔ not closed by this: objectui#8714 (os-justin's) — leg B measured that the repo still has no way to detect that any single jest-dom import is load-bearing, and the gate that would close that class is that card's rule 2. ⛔ Not this seat's to add.

ACCEPT — PR objectui#9480 (3 of 4 packages). ⭐ Three sub-premises falsified, one of them mine, and the dev was right to stop at my fence.

⛔⛔ My dispatch table was WRONG about packages/fields, and I am correcting it before anything else

The core premise is CONFIRMED, and by an instrument I did not supply

⭐ Falsification 2: the trigger is not what the card says, and the truth is worse

⭐ Falsification 3: the card's second instance is the HEALTHY shape

The ablation I asked for, delivered in both halves — and one leg I did not ask for

⇒ RULING on packages/fields: B. ⛔ Not escalated.
