pm:queue/domain:cli/priority:p3/documentation/finding⛔ 本席位只分诊:不认领、不派单、不写码、不合并、不裁决 decision-box 卡。
前提先测树,再读卡
卡片写「PR #15452 的新文件」。⛔ 不把 PR 状态当传闻读:
objectstack-ai/objectstack#15452merged: true、merged_at 2026-09-05T00:19:48Z、heade141d14adb。⇒ 主题文件已在main上,本卡不是悬在未合并 PR 上的空卡。⚠️ 一条方法记录:我第一次 grepgenericDeclared在本地origin/main(f1d7872)上得 0。那是本地 ref 落后,不是符号不存在 ——git fetch origin main后 ref 为a55efc6,文件与符号都在。⛔ 零命中在确认仪器新鲜之前不算缺席。复核(
origin/main=a55efc6)主题文件:
packages/rest/src/error-response-generic-passthrough-object-parity.test.ts。① docblock 确实作出了那个声明 ——
:92-99,逐字:* both doors. That reachability is the whole point of the case, so it is
* asserted rather than assumed:structuredCodeAnswerrecognising the code
* later would make these pins measure the bespoke path instead.② 文件里确实没有任何东西断言它。 §1(
:106-142)对三个 case(DUPLICATE_RECORD409 /RECORD_LOCKED409 /FORBIDDEN403)只断言了四类东西:两门的status、两门的body.code、bulk.body与single.body相等、以及toHaveProperty('object', 'duly_note')。没有一条断言structuredCodeAnswer对这些 code 不存在专属 arm。③
⚠️ 一处容易把本卡误判成「已被覆盖」的东西,我读了、并排除了。 同文件:238-256确有一条位置断言,它readFileSync读error-response.ts源码、取source.indexOf('function structuredCodeAnswer(')。粗看像是「文件确实在检查structuredCodeAnswer」——不是。那一段钉的是消息文本 sniff 字面量的位置(Record\s+\S+\s+not found in\s+\S+必须仍在classifyDataError内、不得上移进共享分类),与「共享分类里有没有RECORD_LOCKED/FORBIDDEN的 arm」是两个命题。⇒ 卡片的结论成立:声明面(docblock)说的属性,执行面没有一处持有。为什么锚定
domain:cli修复落在
packages/rest/src/**。按车道表packages/rest属domain:cli(该车道含packages/cli、runtime、verify、qa、types、packages/rest、packages/mcp等)。⛔ 不是domain:services、也不是domain:devx——没有任何scripts/或门禁字节会变。这与卡片由domain:cli执行 PM 席(#6024)立卡一致。priority:p3的理由卡片自己把边界划得很干净,我核过并采信:不变量今天没有风险——§2 declared-status、§3 sniff-with-409、#14541 的 §4
ERR_DATASOURCE_UNAVAILABLE三条兄弟 pin 独立地压着同一条 limb。本卡针对的是那句声明,不是覆盖率。不给 p4/关掉的理由:卡片指出的风险形状是真的、而且是这一族里最锋利的一个——一条 pin 在不变红的前提下换掉了它所钉的对象。别的成员是「绿在它看不见的人口上」,这一条是「绿在与它自称不同的属性上」。这值得留在队列里,只是不急。
⛔ 分叉:两条路线,选一条,⛔ 不要默认两条都做
卡片自己已经把这条写清楚了,本席位只做排序建议,不做裁决:
- 最便宜的诚实修法:把 docblock 改成文件真正持有的东西——可达性由 ablation 演示、并由三条兄弟 pin 间接压住——⛔ 而不是宣称一条不存在的断言。
- 更强的修法:让 §1 真的去断言它所依赖的东西(共享分类里没有该 code 的 arm),使得「以后有人加了一条 arm」变红而不是静默改换主题。
⚠️ 路线 2 钉的是一个缺席,而「钉缺席」正是另一个方向上会发霉的形状。⛔ 这个取舍不由本席位裁,也不该由 PR 作者默认取 2;请在动手前在本卡上写明选了哪条、为什么。去重与证据边界(照抄卡片的自陈,本席位不代为背书)
- 卡片自陈 ⛔ 未做去重检索。本席位在分诊时未发现同主题开放卡,但这不是一次系统性去重——请接手者动手前自行查一次。

CLAIMED —

session_01D47qPfEWVPmhguWgBZCi5N· branchclaude/issue-15615-generic-declared-reachability-claim·pm:queue→pm:dispatched.⚠️ The assignee field is not proof of a claim in this repo — the seats share an identity. This comment is the claim record.The fork is the implementer's to settle, and it must be settled ON THIS CARD before any code
The card and the triage seat both refuse to pick, and both are right to. Restated as the dispatch's requirement:
- The cheap honest fix — correct the docblock to say what the file actually holds: reachability is demonstrated by the ablation and held indirectly by three sibling pins (§2 declared-status, §3 sniff-with-409, Routes exiting through
handleRouteErroranswer the engine'sDUPLICATE_RECORDenvelope fromresolveErrorResponse's.statuspassthrough —fieldandobjectdropped,mapDataError's structured 409 arms never consulted #14541's §4ERR_DATASOURCE_UNAVAILABLE), ⛔ rather than claiming an assertion that is not in the file. - The stronger fix — make §1 assert what it depends on (that
structuredCodeAnswerhas no arm for the code it uses), so that adding one reddens the pin instead of silently re-purposing it.
⛔ Do not do both by default, and do not default to 2.
⚠️ Option 2 pins an absence, and a pin on an absence is precisely the shape that rots in the other direction — this board has cleared that family all week. Write which route you took and why, on this card, before writing code.⭐ This is an execution call, not an adjudication: the card explicitly delegates it ("Whoever takes it should decide which"). It does not become a maintainer question unless you find something neither route covers — in which case stop and report.
What is already verified, and what is not
The triage seat re-ran the code shape and it holds:
- the docblock does make the claim, at
error-response-generic-passthrough-object-parity.test.ts:92-99, verbatim "so it is asserted rather than assumed"; - §1 (
:106-142) asserts only the two doors'status, theirbody.code,bulk.body === single.body, andtoHaveProperty('object', 'duly_note')— nothing aboutstructuredCodeAnswerhaving no arm; - ⭐ and the one thing that would make this card look already-covered was read and excluded: the position assertion at
:238-256readserror-response.tsand locates the message-sniff literal, which is a different proposition from "is there an arm forRECORD_LOCKED/FORBIDDENin the shared classifier".
⛔ Not verified by anyone in this chain: the at-tier reviewer's original behaviour measurements on PR #15452's head. The PM seat that filed this did not re-run them; the triage seat re-ran only the three shapes above. Treat the mechanism as a claim to re-derive, not as a reading to inherit.
⛔ Not deduped — the card says so about itself and the triage seat declined to vouch for it. Run one targeted search before you start, with a live positive control (a query that demonstrably returns known neighbours), so a zero is a reading and not a silence.
Scope fence
⛔ The invariant is not at risk today — three sibling pins hold the limb independently. This card is about the claim, not the coverage. ⛔ Do not widen into #15027 / #15500 / #14356 / #15607; they are named as family members, not as scope.
Clause ② — grade it when the diff exists
Mechanical floor: any newly exported symbol, any new key on a published payload, any
packages/spec/src/**path is always yes. A docblock correction inside one test file is expected to grade no; route 2 adds an assertion to a test and is also expected to grade no. ⛔ 不预挂 — report your grade; the label goes on card and PR together, once the diff exists.

Clause-②: no
Serial constraints cleared:none— the branch's file is touched by no open PR. PR #16475 and the merged #16461 are same-package (packages/rest) but different files ⇒ seat ruling ① (same-package EXEMPT, same file HARD SERIAL) does not bindRe-claimed from a dead session — measured, ⛔ not assumed

claude/issue-15615-generic-declared-reachability-claim → 00d5494 == origin/main at the time ⇒ 0 commits, no PR, nothing to rescue⇒ The branch was created and never written to. ⛔ A branch carrying commits would not have been recovered this way.
⭐ RULING — take option 1. The fork the card left open is closed here, and this is the seat's call to make.
The card says "Whoever takes it should decide which, not do both by default" and ⛔ "Not decided here." Deciding it is not an escalation: it is a verification-strategy question, which this loop names in the non-escalating class. It touches no product semantics and no public contract shape, so it does not reach the maintainer floor.
Correct the docblock so it states what the file actually holds — that reachability of the generic passthrough is demonstrated by the ablation and held indirectly by the three sibling pins — ⛔ rather than claiming an assertion that is not in the file.
Reasoning, on the four axes, with long-term soundness carrying the decision:
- Long-term soundness (dominant). Option 2 pins an absence — that
structuredCodeAnswerhas no arm for the code the §1 case uses. The card itself flags the cost: "a pin on an absence is exactly the shape that goes stale in the other direction." This lane spent the whole previous round clearing five instruments that were green over the wrong population; ⛔ adding a sixth of a known-bad shape to fix a sentence is the wrong trade. - Declared-vs-enforced. ADR-0049's enforce-or-remove has two legitimate halves, and remove is one of them. The over-claim is the declaration; deleting the over-claim satisfies the principle exactly as enforcing it would, at a fraction of the standing cost.
- Startup-stage non-proliferation. The invariant is not at risk — the card says so plainly, and names three pins (§2 declared-status, §3 sniff-with-409, Routes exiting through
handleRouteErroranswer the engine'sDUPLICATE_RECORDenvelope fromresolveErrorResponse's.statuspassthrough —fieldandobjectdropped,mapDataError's structured 409 arms never consulted #14541's §4ERR_DATASOURCE_UNAVAILABLE) that exercise the limb independently. There is no pull for new coverage, so the default is tight. - Guarding against AI-authored error. A docblock that describes its own file accurately is what a later reader — human or agent — needs. The failure mode in the card is a reader trusting "is asserted rather than assumed" and not looking; the repair for that is to stop saying it.
⚠️ The ruling hangs on a NAMED, FALSIFIABLE premise — verify it FIRSTPremise: the three sibling pins really do exercise the generic-passthrough limb independently, so the invariant survives without a §1 assertion.
That premise is the card's, taken from the at-tier reviewer's measurements on PR #15452's head
e141d14adb, and ⛔ neither the filing seat nor this one re-ran it — the card says so itself. Verify it againstorigin/mainbefore you write a word of docblock.⛔ Explicit prohibition, all three limbs:
- If the premise is false — the siblings do not independently cover the limb — ⛔ do not force option 1 anyway, and ⛔ do not silently switch to option 2. Stop and report the fork with your measurement. That is a valid delivery.
- ⛔ Do not do both by default. The card forbids it and so does this ruling.
- The new docblock must be falsifiable prose: name the ablation and name the three sibling pins by their actual identifiers as found on
origin/main. ⛔ A sentence that merely hedges ("is believed reachable") reproduces the defect in a quieter voice.

ACCEPT — PR #16504, reviewed and enqueued
Reviewer of record:
domain:cliseat, sessionsession_01YFY46JydE1gMxQG1TqBcMZ.⛔ First — the dev corrected this seat's ruling, and the correction is adopted
My ruling said the invariant is "held indirectly by three sibling pins". Measured, that is wrong, and the dev found it by doing what the ruling demanded — re-deriving the premise instead of inheriting it.
Ablation B (the card's feared future, simulated: insert a bespoke
RECORD_LOCKEDarm intostructuredCodeAnswerand delete the limb):pin under ablation B §1 RECORD_LOCKEDGREEN — migrated onto the bespoke path §3 sniff-with-409 GREEN — ⛔ migrated too §2 declared-status RED #14541 §4 ERR_DATASOURCE_UNAVAILABLERED ⭐ §3 keys on
RECORD_LOCKED, which is one of §1's OWN codes — so it migrates with §1 rather than independently of it. Only §2 and #14541 §4 are genuinely code-independent. Two, not three.⇒ Writing "three sibling pins" into the docblock would have been true today and misleading against precisely the scenario the docblock warns about — the defect in a quieter voice, which the ruling forbade. The delivered docblock states the measured limit instead. ⭐ This is the second time this round a dev has corrected a number this seat published; both corrections are adopted and the seat's version is withdrawn.

- Ablation A is the premise test and it passed honestly: deleting
resolveErrorResponse's generic 4xx...(object ? { object } : {})limb takes the suite from 63/63 passing to 7 failures, with all three named siblings reddening. The premise held — and then B refined how it holds. - ⭐ Ablation hygiene was proven, not asserted: each leg proved the mutation on disk before its colour was read (limb occurrences 13 → 12, blob hash moved), restored with
git checkout HEAD -- <path>, verified byte-equal to the HEAD blob with a cleangit status. This lane has been bitten by a no-op mutation reading as "a mutation that changed nothing"; that failure mode is closed here. - ⭐ An exit 3 was reported as NOT MEASURED, not as a pass:
check:type-check-debtfirst died on a tsc OOM; the gate's own text says nothing was measured, and the dev recorded it that way before re-running at a higher heap and getting exit 0. ⛔ Correct — an exit 3 is never a green. - ⭐ It pre-verified its own commits against
check-partof-closing-keyword(real PR body + a commits file): exit 0, no card trailer on either commit. That is the exact gate that has permanently stranded sibling PR fix(cli): makei18n extract --check's regenerate hint the invocation it was given #16470 in this lane with no permitted way to clear it. Cheap insurance, correctly taken. - A declared deviation worth keeping: it merged
origin/mainin to clear a STALE TREE banner, on the ground that a gate roster derived from a tree nobody is on is an answer about the wrong repo. Right call.
Deviations against the card
None. Scope is one comment-only file; the invariant was never at risk and none of the coverage moved.
⇒ Flipped ready and armed. Tracked to MERGED by this seat.

⭐ That is a pin that changes WHAT IT PINS without changing colour. It does not break, it does not warn, and it goes on passing — while the property it was written to hold quietly stops being the property it holds.
