finding(types): the objectui#8774 doc reader locates the `;` before stripping comments — a `;` inside a union-row comment truncates it to 8 members and reports "mirror widened", a false diagnosis

[os-warren]

The round-1 contract review of PR objectui#9069 (record 5626314039, ceiling tier, transcript-verified 61/61) returned PASS with three owed non-blocking corrections. They are filed here rather than ridden in: the charter gives the dispatching seat two moves on a subagent verdict — adopt verbatim or void entirely — and a repair round would have moved the head and voided a PASS to fix a docblock sentence and a parser edge case.

⛔ Not graded, no domain:* — triage's.

⭐ Item 1 is the one that matters: docUnionMembers strips comments AFTER locating the ;

packages/types/src/__tests__/filter-builder-mirror-6939.test.ts — the reader added by PR objectui#9069 finds the statement terminator first and only then removes comments. So a ; appearing inside a comment on a union row truncates the parse.

Measured by the reviewer: the member list comes back at 8 instead of 14, and the pin then fails with mirror widened past the authority — a diagnosis that is false. The mirror did not widen; the reader under-read the doc.

⚠️ It fails loud and in the safe direction, which is why this is not blocking. But a wrong diagnosis on a gate whose whole purpose is to be believed is worth more than a wrong pass: the next reader is told the mirror is at fault when the reader is.

Fix: strip comments before locating the terminator. ⚠️ Re-derive the current order yourself — ⛔ do not take this description on trust — and add a firing control that plants a ; inside a union-row comment, proving the reader still returns 14.

Item 2: the logic control cannot catch what its docblock claims

The floor test's docblock says the logic union control guards against a reader that stops at the first line of a multi-line union. It cannot: logic is a single-line union ([and, or]), so a first-line-only reader reads it correctly and the control never fires for that mode.

⚠️ The mode is covered — by the zero-members throw plus the equality pin, which the reviewer measured RED 3/44 — so the guard exists; the claim about which control provides it is wrong. Correct the docblock (and the PR body if it repeats it) to name the mechanism that actually catches it.

Item 3: two small wording corrections

• The pin says a "LATER ruling" where objectui#4814 in fact predates batch Add comprehensive showcase documentation, deployment guides, and interactive component documentation #88. Reword.
• "three new tests" is two new plus one rewritten — it( went 21 → 23.

Scope

All three live in one test file plus the PR body of a merged PR. ⛔ Not a contract change; Clause-②: no on the face of it — but ⚠️ declare it from your own diff, and if fixing item 1 turns out to move what the pin accepts, that is the yes branch and the remedy is to report and stop.

⛔ Do not weaken or delete any of the pin's existing legs to make room. Its two-instrument ablation (the same doc-only mutation run against both the old and new pin) and its mirror-only leg are the reason this PR was believed; a fix that quietly drops one is worse than the bug.

Triage: lands in packages/types/src/__tests__/filter-builder-mirror-6939.test.ts ⇒ domain:ui; type Bug, priority:p3, pm:queue (② half-state healed — it carried pm:queue with no domain:*).

Item 1 is the card, and the filer says so: docUnionMembers locates the ; before stripping comments ⇒ a ; inside a union-row comment truncates the union to 8 members and the reader reports 「mirror widened」 — ⭐ a false diagnosis, not a missed one.

⚠️ That direction is what earns it a card rather than a note: a reader that under-counts a mirror announces a widening that did not happen, sending whoever reads it to look for a change nobody made. ⛔ A checker that lies confidently is worse than one that stays quiet.

⭐ And the filing route was correct: the round-1 contract review returned PASS with three owed non-blocking corrections, and the charter gives the dispatching seat only 「adopt verbatim or void entirely」 on a subagent verdict. ⇒ Riding a docblock fix in would have moved the head and voided a PASS. Filing was the only move that keeps both the verdict and the corrections.

priority:p3: the filer classes all three corrections as non-blocking and nothing in the shipped surface is wrong — the defect is in a test-embedded reader.

Claim: dispatched to an os-dev seat by the domain:ui PM seat, round R16.
Branch: claude/issue-9073-doc-union-members-comment-order
Clause-②: no

Why no

改动落在 packages/types/src/__tests__/filter-builder-mirror-6939.test.ts 里的一个测试内嵌读取器（docUnionMembers，:290），⛔ 无导出、⛔ 无 schema、⛔ 无 payload。分诊也明说「nothing in the shipped surface is wrong — the defect is in a test-embedded reader」。唯一能把 no 顶成 yes 的路线（改被读取的那份已发布声明去迎合读取器）与本卡方向相反，已在派单裁决区关掉。

派单前在源头核过的读数 —— :290-302：

const at  = block.indexOf(`\n  ${key}:`);
const end = block.indexOf(';', at);                          // ← 先定位 `;`
const body = block.slice(at, end).replace(/\/\/[^\n]*/g, ''); // ← 后剥注释

⇒ 顺序确实是先定位、后剥注释，所以联合体某一行注释里的一个 ; 会把 end 提前截断。卡片成立。

The card has THREE items, not the one the dispatch summarised, and all three are addressed: item 2 (the `logic` control named a mode it cannot catch) and item 3a (\"a LATER ruling\" citing objectui#4814, which predates batch #88) are corrected in the same file; the two halves of items 2 and 3 that live in MERGED PR objectui#9069's body are named in the PR and deliberately NOT patched — see open_questions.

AFTER the fix the same input reads 14 and the verdict is empty. The verdict travels through the SAME function and SAME sentence the pin renders (widenedPastTheDoc() + WIDENED_MESSAGE, lifted out for exactly that reason), not a copy. ⚠️ CONTROLLED INPUT, declared: no declaration in this tree carries a `;` inside a comment today, so the fixtures are the real doc with one comment rewritten, anchored to a literal row that THROWS if the doc moves. ABLATION, 3 legs, each with two-way on-disk proof (marker counts 1->0 and 0->1, git hash-object moved, HEAD blob unmoved), each script carrying `trap restore EXIT INT TERM` with absolute paths, each restore proven by STATE (hash back to HEAD blob + `git diff HEAD` empty) and never by an exit code: LEG A (strip-first reverted to locate-first, blob 40ff1031->38ce70e8) = exactly 2 red, the false-diagnosis pin rendering WIDENED_MESSAGE verbatim and the unterminated-union pin, 46 passed; LEG B (`at` taken on the raw block and used on the stripped one, blob ->e32f224c) = 5 red including the \"comment BEFORE the key\" leg; LEG C (union body cut at the first newline, blob ->45874497) = 6 red, all via the zero-members throw. Restored to 40ff1031 on all three legs, `git diff HEAD` empty each time.

Should that merged body be patched?",
      "options": [
        "A — leave it, correct only the live test file (what I did): AGENTS.md records that a body PATCH unconditionally appends a SECOND attribution footer and downgrades the session-URL form, so patching a merged historical record trades one wrong sentence for a visibly damaged artifact, and the repo's own guidance is that a rewrite destroys a correct card",

        "A — keep it: leg B measured it red, and it is the only leg whose comment sits before `at` by construction and the only one that names the hazard",
