finding(tests): the comment projection at three packages/types readers is inert on every subject the tree has — removing it entirely changes nothing, so nothing would notice it being lost

The comment projection at three packages/types readers is inert on every subject the tree has today. Measured during objectui#9751: over 16 interface bodies, the member map produced with the projection and with no projection at all are identical, and the test file still passes with the projection removed.

⇒ these readers carry a guard that nothing exercises, so nothing would notice if it were deleted, weakened, or quietly reverted to a hand-rolled regex. ⛔ That is not a claim the guard is wrong — it is correct, and objectui#9761 just moved it onto scripts/js-comment-mask.mjs with zero behavioural risk precisely because it is inert. The finding is that its correctness currently rests on a classification argument and not on anything that reddens.

The carriers

packages/types/src/__tests__/overlay-node-slot-doc-types-7082.test.ts
packages/types/src/__tests__/alert-dialog-read-dialect-7104.test.ts
packages/types/src/__tests__/overlay-trigger-union-7081.test.ts

Each strips comments out of a .ts source before counting interface members. The hazard the original docblock named is real — prose inside a block comment that looks like a member row would be counted as one — but no subject in the tree spells it.

Why this is its own card and was not folded into objectui#9761

⛔ Adding a forcing fixture inside that pull request would have mixed a behaviour-preserving conversion with a new assertion, and afterwards a reviewer could not tell which of the two any test result was about. The seat ruled option A (land the conversion as is, state the inertness as measured) with this as the follow-up. Record: objectui#9751's ACCEPT and landing comments.

Sketched direction (⛔ not chosen — a triage call)

Give the projection something to defend: a fixture interface body carrying a member-shaped line inside a block comment, pinned so the member count is wrong when the projection is removed. ⚠️ The fixture has to be a subject, not a synthetic string handed to the reader — the distinction objectui#9748 drew between "the file's measured behaviour" and "the shape the file does not have today" applies here too, and a pin that blurs it teaches the wrong thing.

⛔ Not a request to convert anything: objectui#9761 already did the conversion. ⛔ Not objectui#9751 (that was residue plus the recurrence channel, and it is closed).

Provenance

Surfaced by objectui#9751's dev as an open question after its reverse ablation came back green, ruled by the domain:devx @ objectui execution seat, session_015h79niBMyoB1xcaQje3uiz, R73, 2026-09-18. The measurement is the dev's; the ruling to card it rather than fold it in is the seat's. ⛔ This seat does not grade, route or prioritise.

The card's '16 interface bodies' is NOT reproducible; 20 is the measured number. Triage's escalation condition is NOT met: replaying every captured body through the readers' own member regex with and without the projection gives an identical member map on 0/20 -- no live defect, no p2, the fixture stays the right deliverable. The projection is nevertheless exercised (it deletes prose in 17/20 bodies, 11754 bytes in the AlertDialogSchema body alone); it just never changed an answer. Each of the three readers now declares `CommentProjectionForcingSubject`, a subject on disk whose body carries a member-shaped row inside an ORDINARY block comment (no star gutter, so the row sits on the two-space anchor `members()` matches), read off disk and extracted by the reader's own interfaceBody + members -- a subject, not a synthetic string.

CI	36 of 36 green, 36 distinct names — waited for every check to complete.
Path surface	4 files. The three readers are inside the declared area; `.changeset/9768-…md` is outside it (see deviations). Fence re-measured over 18 open pull requests / 1857 filenames, fully paginated; positive control `.github/workflows/ci.yml -> #9584` fired; the three readers are held by #9814 alone and `scripts/js-comment-mask.mjs` and `packages/types/src/overlay.ts` by nobody.
⭐ Shape	Purely additive — 0 deletions in all four files. That turns "no reader behaviour, regex or subject list moved" from a claim into a structural fact, which is the strongest form the deliverable's ⛔ do not change its behaviour could take.
New CI context	none; no workflow file touched.
Governed surfaces	none.
Clause-②	`no` and true: this adds a subject and two assertions, relaxes nothing.
Pushed artefact	commit trailer `Co-Authored-By: Claude` + `Claude-Session:`, no model identifier.
The lock	the turbo-build verifications went through `os-verify-lock.sh` with their verdict lines quoted.

The three things this dispatch demanded, checked here rather than taken on report

The population was established mechanically, not inherited — stripComments instrumented, the readers run, 67 calls captured over 20 distinct (file, interface) bodies. ⇒ ⛔ the card's "16" is not reproducible, and the card is this seat's. Recorded as a correction to the card, not a footnote.
Triage's escalation question was answered against that population: every captured body replayed through the readers' own member regex with and without the projection ⇒ identical member map on 0 of 20. No live defect, no p2, and the fixture remains the right deliverable. ⭐ With the sharper half stated rather than smoothed over: the projection is doing work — it removes prose from 17 of 20 bodies, 11,754 bytes in the AlertDialogSchema body alone — it has simply never changed an answer.
The fixture is a subject, ⛔ not a synthetic string: interfaceBody(readFileSync(OWN, 'utf8'), OPENER, OWN) — read off disk and extracted exactly as a declaration is. And the pin asserts the member list (['real','label'], becoming ['phantom','real','label'] when the projection is dropped), ⛔ not a count.

⭐ What it added that was not asked for, and is the best part

A second leg on the new pin:

it('the subject really carries a member-shaped row inside a block comment — read off the UNPROJECTED text')
"Without this leg the pin below passes just as well against a subject that lost the row, and an empty guard reads exactly like a live one."

⇒ a fixture that silently lost its forcing row would leave the new pin green — the new guard would become the inert guard it exists to cure. That is this card's own thesis applied one level down, unprompted. The subject also carries a ⛔ warning against adding a * gutter or "tidying" the row, because either would un-force it without any test noticing.

Landing probe, pre-validated against `main`

	token	reading	why it is that token
fire	`export interface CommentProjectionForcingSubject {`	0 → 2 per reader	the declaration and the `OPENER` the pin must name to find the body
fire	`expect([...rows.keys()]).toEqual(['real', 'label'])`	0 → 1 per reader	the leg that reds, asserting the member list
fire	`read off the UNPROJECTED text`	0 → 1 per reader	the second leg above
control	`const bare = stripComments(body);`	1 → 1 per reader	reasoned first: the deliverable forbids changing the reader, so if `members()` moved the fix exceeded its mandate
control	the `counter-probes` describe block	1 → 1, 0 → 0, 1 → 1	reasoned first: the dev measured those probes as themselves inert and correctly left them alone — movement either way is widening. Present in 2 of 3 readers, measured per file rather than assumed

⚠️ This probe has no clear leg, because the change deletes nothing. That is a property of the change, ⛔ not a gap in the probe.

⚠️ And the probe first printed a disagreement that was mine, not the change's — I had expected the forcing subject once per reader and the counter-probe block in all three. Both expectations were wrong; the readings are right. Recorded because it is the third time this shift that the faulty instrument was this seat's own.

Deviations

.changeset/9768-comment-projection-forcing-subject.md sits outside the declared areas — a required artefact of the changeset gate, ⛔ not a widening.
Reported and correctly not filed: the pre-existing "JSDoc stripping does not eat real rows" counter-probe reads as though it exercised the projection but does not — its member-shaped line sits behind a docblock gutter while members() anchors on exactly two spaces, so it passes identically with the projection removed. ⭐ A probe mistaken for a guard, in the same file, of the same class as this card — and this pull request supplies the thing it was mistaken for.

⛔ A correction this seat owes, and it is about its own instrument

This landing sat 20m21s in the merge queue — past the 20.2-minute figure this seat has been reporting as an ejection margin — and it merged normally.

⇒ the two numbers were never comparable. timeout-minutes: 20 bounds a job's own run; queue dwell is queueing plus the build. objectui#9635's ejection was a job hitting its ceiling (20.2 min of run against 13.1 min on the PR head); the 20 / 19m26s / 18m46s / 20m21s figures are dwell. Two different clocks, and this seat has been reporting them as one — including to the maintainer, as a standing open item about a "pattern in the margin".

⭐ That is the same error class this lane keeps cataloguing — measuring a different quantity than the claim names — committed by the seat, three times this shift now, and this is the one that reached a maintainer-facing item. The dwell figures stand as dwell; ⛔ they say nothing about the job ceiling, and the "three landings in a row inside the ejection margin" framing is withdrawn.

What the card produced. The population the card asserted (16 interface bodies) is not reproducible — 20 is the measured number, established by instrumenting stripComments rather than inherited. Triage's escalation condition was answered against that population: identical member maps on 0 of 20 ⇒ no live defect, p3 stands. ⭐ And the sharper half: the projection is doing work — it removes prose from 17 of 20 bodies, 11,754 bytes in the AlertDialogSchema body alone — it had simply never changed an answer. It now has a subject that makes it change one.
