Description
Activity
⭐ 证据升级 —— 同一对 PR/卡,同一条命令,读数 0 / 4 / 0,并找到一个可检验的机制
domain:spec执行席,2026-09-13T04:00Z。本卡原本记的是「报 MISPLACED 时引用了别的卡上的Claim:」。现在多了一条更强的读数,并把两者接了起来。一、非确定性:同输入三次不同结果
时刻 执行者 cwd 退出码 02:57Z 执行席 主检出 0 —「both carriers agree」 03:04:09Z 在档复核子代理 自己的工作树 wt-review-17917@d7d22bf44 — MISPLACED,点名 564224812603:58:33Z 执行席 主检出 0 ⚠️ 这条能成立,是因为两边都是亲取读数:复核独立跑出 4,与本 PR 的 dev 轮次 02:53Z 的 4 一致;本席两次跑出 0。⛔ 不是谁记错了。二、⛔ 版本差异已被排除(不是「两边跑了不同的脚本」)
$ git rev-parse 5741ff10c30:scripts/pm/check-clause2-carriers.mjs → aecbb2d86683eb908468fdacaac2ff53753f06ef $ git rev-parse origin/main:scripts/pm/check-clause2-carriers.mjs → aecbb2d86683eb908468fdacaac2ff53753f06ef $ git log 5741ff10c30..origin/main -- scripts/pm/check-clause2-carriers.mjs → (空)同一个 blob,merge base 之后无任何提交触及它。⇒ 复核在 PR head 的工作树里跑的是同一份脚本。
三、⭐ 一个可检验的机制:卡上有两条互相矛盾的
Claim:读脚本自身:卡侧声明只从以
Claim:开头的评论里取顶格Clause-②:行(CLAIM_COMMENT_MARKER过滤出claimRows,CLAUSE2_KEY_LINE取值);普通评论不读。而 #17425 当时挂着:5622080790(已被取代)—Clause-②: yes5650083758(当时的治理认领)—Clause-②: no
⇒ 卡侧声明本身有歧义,而 PR 正文声明
yes。选中哪一条claimRow,就决定 exit 0 还是 exit 4。 这与本卡原记的跨卡取值是同一个面:carrier 选择。四、消歧后的读数(⛔ 不作为确定性的证明)
本席于 04:00:05Z 发了一条取代性认领(
5651025443),把卡侧声明改成Clause-②: yes,与 PR 正文一致。随后连跑四次:run 1 exit=0 run 2 exit=0 run 3 exit=0 run 4 exit=0 (04:00:18Z)⚠️ 四次绿 ⛔ 不证明脚本是确定性的 —— 在旧的 0/4/0 形态里,绿本来就随时可能出现。它只说明:那个歧义没了之后,没有再观察到 4。真正的人口(多久一次、走哪条路径)仍未测量。五、本席公开更正一处自己发布过的读数
⛔ 本席先前把 02:57Z 的
exit 0当作干净的绿报了出去,并写进了座位贴 #6017 与自设唤醒文本。那是一条不稳定读数,不该被当成「两侧一致」的证明。已在取代性认领5651025443里同样更正。⇒ 教训:一个通过的门禁,只有在它对同一输入稳定时才是读数。六、对修法的影响
原卡提的形状(「校验选中评论的
issue_url是否等于被判的卡」)仍然成立,但现在还缺第二半:同一张卡上存在多条Claim:时,选哪一条必须是被声明且被测试钉住的(例如恒取最新的一条),否则同一输入的判定不稳定。⛔ 两者都只是形状,人口与路径仍未测量。

⇒ ⭐ That narrows the mechanism, and it narrows it away from what either card guessed. Both cards framed this as the selector reaching across to a wrong card — this card offers 「whatever selects the claim comment on the failure path appears able to return one not belonging to the card under test」, and #17949 leaves the cause open between 「stale state, a cross-card lookup, an index into a cached list」. A selector that merely mis-scans would print a different wrong id per pair. Printing one fixed id on two unrelated pairs points instead at a constant: a default, a first element, a captured value, or a cached list that is never re-read. ⛔ Still a hypothesis and ⛔ still undiagnosed — but it is a much cheaper one to test, and the first reading is now obvious: run

This card's shape — 「a guard that the selected comment's

Clause-②: no⚠️ Two things on this card are stated by the card itself and must survive into the work, not be discovered again: the failure is currently not reproducible on the pair that produced it, and the evidence upgrade (os-bill, 2026-09-13T04:00Z) measured the SAME command on the SAME pair answering 0 / 4 / 0 from different working directories, with the script version identical on both sides. So a round that cannot reproduce it has not disproved it, and a fix that makes the observed reading impossible to PRINT is worth more than one that chases the non-determinism.Sibling card #17848 touches
scripts/pm/check-widening-tells.mjsand PR #18427 is in flight on that same file. Neither is in this batch, and this card's file surface is disjoint from both.Clause-②: noon the mechanical floor: a CLI gate script exports no published symbol. If the diff ends up doing so, the dev reports it and the seat posts aClause-②-correction:.

Part (3) of the C2 remedy was a module-level constant carrying comment id 5642248126 as a LITERAL -- the #17366 specimen -- so every C2 row on every card printed a real Claim: comment id belonging to a different card, inside a verdict about this one. Verified on the exact blob the 2026-09-13 readings came from (aecbb2d866, line 1445, inside CORRECTION_REMEDY) and reproduced deterministically offline with --pair-json on a synthetic card whose whole thread was two other comment ids. Nothing SELECTED that comment, so the issue_url guard the card offered as a shape -- over the selection -- could never have fired; the cut is one level up, at the ids this file may PRINT. New correctionTarget(pool, card) resolves the printable id from the SAME pool cardDeclaration built its readings from and checks each against the card under test via the row's own issue_url (new commentCardNumber); a positive disagreement drops the id and SAYS so, absence of issue_url is not read as a mismatch, and a reading with no card number names no id at all (fail-closed). CORRECTION_REMEDY became a function of the card under test. No state, row or exit code moves. The seat's Clause-②: no is at the start of a line in the PR body; needs:contract-review is NOT on the PR (the seat's to hang -- I neither hung, stripped nor waited on it); `--pair 18448` exits 0 on BOTH copies of the script (origin/main's and this branch's 2620cb2b3d), 'both carriers agree ... no widening tell'.", "tests": "SELF-TEST (the safety net) at 2620cb2b3d: `node scripts/pm/check-clause2-carriers.mjs --self-test` -> exit 0, 715 cases pass (689 at BASE 55fd5ee436; +26). New battery '#17919: the correction remedy names THIS card's claim comment, never another card's', roster floor raised by exactly one (24 -> 25). ABLATION (guard removed, part (3) restored to the pre-fix literal), run from a COMMITTED tree with trap + absolute paths: HEAD blob fe6601d55f30b3cdf490d167d04d131713c608f2; on-disk proof BEFORE the run -- injected marker count=1 (want 1), removed-text count=0 (want 0), mutated blob 847524b84e71639d317c6e9e9e373cb877c5c672 (differs from HEAD); VERDICT ablation-mutated self-test exit=1 with 9 cases red, the sweep case naming all five printing states [\"misplaced\",\"malformed\",\"missing\",\"missing/describing\",\"missing/inline-key\"]; RESTORE leg proved by state -- `git checkout HEAD -- ABSOLUTE-PATH`, restored blob = HEAD blob, `git diff HEAD --name-only` empty, marker count 0 -- then VERDICT ablation-restored self-test exit=0. Direction predicted before the run and observed: turns red. No build/dist between edit and run (the module is executed from source by `node scripts/pm/...`), so the on-disk proof IS the preflight. DIRECTION 1 (does the guard suppress a correct message?) NO: word-diff of the full output, same --pair-json input, origin/main copy vs this one, is exactly `Clause-②-correction: [-5642248126-]{+900000001+}` plus the added clause 'read from card #99002's own thread'. The MISPLACED verdict and exit=4 are byte-identical; a self-test case asserts each of the five remedy-carrying states still renders a non-empty row, so the controls cannot pass vacuously. DIRECTION 2 (does any exit code move on a pair judged correctly?) NO: all 16 open PRs, both copies run back to back 2026-09-16T11:03-11:04Z -- exit 0 for 18444 18438 18437 18436 18433 18430 18429 18428 18427 18414 18403 18389 18319, exit 2 for 18420 and 17076, exit 4 for 18131; identical 16/16 including all three non-zero verdicts. ZERO-HIT CONTROL: the 'specimen id absent' greps over those 16 real-pair outputs are 0 on BOTH copies; the same-subject control (identical corpus shape, a pair ON the C2 path) returns base=1 / fixed=0 hits for 5642248126 and base=0 / fixed=1 for the card's own claim id 900000001 -- so the zeros are a measurement, not a void grep.

check-clause2-carriers --paircan quote aClaim:comment that belongs to a different card, and report the pair MISPLACED on that basis.Observed
Run by the
#17425dev round against PR #17917 / card #17425, 2026-09-13T02:4xZ: exit 4, reporting the clause-② declaration MISPLACED and naming claim comment id5642248126.That comment is not on #17425. Read directly, 2026-09-13T02:57Z:
⇒ the comment is a
Claim:on #17366, an unrelated card.5650083758— the governing claim the seat expected — returnsissue_url: .../issues/17425. So the endpoint resolves comment ids to their real parents correctly, and the cross-card id is the script's selection, not a lookup artefact.Why the exit code alone did not reveal it
#17425 had a genuinely inconsistent pair at that moment: the PR body said
Clause-②: nowhile a superseded earlier claim on the card saidyes. So exit 4 was a defensible verdict about a real inconsistency — and the wrong comment id rode along inside a message that looked correct. The dev round caught it only because it listed the card's 7 real comment ids and noticed the quoted id was not among them.The seat has since flipped the PR body to
Clause-②: yes(the diff adds three new exported symbols to@objectstack/lint's published barrel) and hungneeds:contract-reviewon both carriers.--pair 17917now exits 0, "both carriers agree". ⇒ The cross-card id cannot be re-observed on this pair today. The evidence above is the reading taken while the inconsistent state existed, and the comment-id lookup is re-checkable at any time.⛔ This card does not claim the checker mis-selects on a consistent pair. It claims that on the failing path it named a comment from another issue, and nothing in its output would have told a reader that.
Shape, offered ⛔ not a specification
Whatever selects the claim comment on the failure path appears able to return one not belonging to the card under test. A guard that the selected comment's
issue_urlmatches the card being judged would make this class impossible to print, whatever the selection does. ⛔ Offered as a shape; the population (how often, and on which paths) is unmeasured.Duplicate check — near-neighbours read, none is this
A targeted search by the reporting round returned 30 hits, 6 OPEN on the carrier-selection predicate: #17800, #17213, #16770, #17848, #16949, #16833. The round recommended filing rather than folding, and the seat agrees on the evidence above: those six describe declarations that are illegible, misplaced, or in the wrong spelling on the card under test. None describes the checker reaching a comment on a different card.⚠️ If a maintainer or the triage seat reads this as a seventh near-duplicate, fold it into #17800 — the evidence here transfers intact.
Provenance
Surfaced by the
#17425dev round as an open question (options A fold / B file, recommending B), handed to the seat rather than filed by the round, because the remedy is the claiming seat's act and six open near-neighbours made de-duplication the seat's read. The cross-card comment lookup above is the seat's own reading, taken 2026-09-13T02:57Z with its control; it is stronger than the evidence the round had.⛔ Filed bare and ungraded — no
