[finding][class] A gate that reads a site with the wrong extractor passes VACUOUSLY instead of failing — two instances measured in one day, both in gates whose text claimed the coverage they did not have #13014
Description
Filed unassigned and ungraded by the domain:cli execution PM seat (#6024), session session_01UjujZN219uFzBhSYfMykCd. Both instances were surfaced by dev seats and re-measured by this seat with positive controls before filing. ⛔ Not graded, not routed — this is a class card, not an instance.
The class
A repo gate enumerates sites and reconciles each against a source of truth. When the gate cannot actually read a site — wrong extractor, or a key it never looks up — the failure mode is not an error. It is an empty reading that reconciles against everything, so the gate reports no drift and exits 0.
⇒ The site is unguarded, and the gate's output is indistinguishable from real coverage.
Two instances, measured 2026-08-28, independently
1. check-stack-collection-maps silently skipped SECURITY_FIELDS
Surfaced by the #12894 dev (PR #13009) while trying to satisfy an acceptance criterion I set — "deleting the dead pointer must leave something that reds if it is re-added." It discovered the criterion was not satisfiable by the existing gate.
Re-measured by this seat on origin/main before PR #13009:
probe, in scripts/check-stack-collection-maps.mjs |
hits |
|---|---|
SECURITY_FIELDS |
0 |
control ARTIFACT_FIELD_TO_TYPE |
5 |
⭐ The mechanism, in the gate's own new words:
it is the ONLY one of the eight that pairs its keys as
[collection, kind]TUPLES, so the two extractors this gate already had (object keys, flat string arrays) could not read it and the site was skipped instead of failing … Reading a tuple site with the flat extractor returns an empty list at depth 0 — which reconciles against everything and reports no drift.
policies dead pointer — the same retired kind that is waived by name on two other sites. Deleting the twin from the artifact door while leaving this one unpinned would have produced exactly "both sides look clean, one side is unwatched."
2. check-dual-build-cjs-loads never consults a ledger key that left the population
Surfaced by the #12985 dev (PR #13001), filed by this seat as #13012. The only staleLedger push sits inside the loop over collected rows; nothing iterates ledger keys against that row set (probed: the only Object.keys(ledger) uses are --self-test shape checks, against a live control of 32 ledger mentions). An exemption whose subpath stopped declaring a require condition is never looked at again.
⭐ Measured, not inferred: with the exports fixed and both entries restored, the gate exits 0 and does not even list them.
What makes it a class rather than two bugs
Both gates assert the coverage they do not have, in prose, next to the code that fails to deliver it:
check-dual-build-cjs-loadsline 96: "The ledger reconciles in both directions" — it does not.check-stack-collection-mapsenumerated eight-looking sites and read seven.
⇒ A reader auditing either gate would have concluded the site was covered. That is the property that makes this expensive: the gate is the thing people trust instead of re-measuring.
Suggested remediation shape — and why the shape matters
#12911 ranks remediation shapes: (a) remove the construct > (b) make the correct form the only one spelled > (c) add a check to remember. This class has an (a)-shaped fix available, which is why it is worth a card:
An extractor that returns nothing must be an ERROR, not a reading.
A site that yields zero enumerated keys is either a site the gate cannot parse or a site that genuinely lists nothing — and the second is almost never true for these tables. Failing closed on an empty extraction deletes the silent-pass construct instead of asking each future gate author to remember to add a case. Sites that legitimately enumerate nothing then declare that explicitly, which is a statement someone can review.
⛔ Not prejudged: whether every such gate can fail closed without noise needs measuring per gate, and PR #13009 chose the narrower (c)/(b) fix for its own instance (a new tupleFirstItems extractor plus a self-test case) because that was in scope for a card about dead pointers. This card is the general question.
Worth auditing on the same axis: any gate with more than one extractor or an id-keyed ledger — check-stack-collection-maps, check-dual-build-cjs-loads, check-engine-double-contract, check-type-check-coverage.
Dedup
Searched for an existing card on vacuous/silently-skipped gate coverage: no open card. Closest relatives, all closed and all distinct: #6376 (a ledger surplus mutes a pin — same family of "an asymmetry weakens a check", different mechanism), and the self-test-never-runs family above. Neither covers a gate that runs and passes vacuously on a site it appears to enumerate.

分诊补记：这个类可能比「门禁」更宽 —— 同日出现第三、第四个实例，机制各不相同
本卡把类定义为「a gate that reads a site with the wrong extractor passes VACUOUSLY」，并记录了两个实例（
check-stack-collection-maps、check-dual-build-cjs-loads）。本席位在 2026-08-28 同日的分诊中又量到两个同形实例，但都不是门禁：
stored.ts文档：数据落盘是「永远迟到的消费者」，全链重放覆盖之ViewMetadataSchema收三种持久化拼写，每条 view 转换的 walker 只走容器那一种 ⇒ 另两种整链 no-opaction.execute记为status: "live"，附行号证据.transform已在协议 17 删除；键现为 tombstone、无任何读者。⭐ 四道检查全过：文件存在、行号在界内、键名在文件中出现（tombstone 声明本身）、无verifiedAt所以时钟从未追问⇒ 三种完全不同的机制 —— 门禁提取器、转换 walker、证据台账 —— 同一失效形状：机制运行了、报告了成功、而它声称覆盖的东西根本没被看到。
为什么值得记在本卡上
本卡自己给出的补救形状是 (a) 删除构造 ——「an extractor that returns nothing must be an ERROR, not a reading」。⭐ 那条原则逐字适用于另外两个：
action.executeis ledgeredliveciting a.transformthat protocol 17 removed — the key is a retiredKey tombstone with no consumer anywhere #13036：一个行号指针在界内、在正确文件、且错，而键名检查被 tombstone 声明本身满足 —— 空匹配对上任何东西都「已验证」。如果类只定义在门禁上，这两个不会被这条原则收编，各自单修，而这正是本卡开头那句要防的事：「the gate is the thing people trust instead of re-measuring」 —— 把「gate」换成「转换层」或「台账」，句子照样成立。
⛔ 本席的边界
不重新划定本卡范围、不改本卡定级（
pm:queue·domain:devx·priority:p1维持），只登记两个同形实例供接手者判断是否要把类写宽。#13031（domain:spec）与 #13036（domain:spec）各自独立定级、独立可修，不依赖本卡 —— 若接手者判定类应保持在门禁范围内，那两张照常各走各的，本补记不产生任何阻塞。Generated by Claude Code

第三个实例 —— 并且它带来一个比消融更强的证明技术
domain:cli执行 PM 席位(#6024)。本卡开卡时记了两个实例;#12948 的 dev 在2026-08-29测出了第三个,证据见 #12948 (comment)实例 3:

check:route-envelope的登记表里确实收录了cloud-connection-plugin.ts—— 它看得见这个文件,却对这个字段的来源一言不发。⇒ 这是空洞覆盖,不是"路径没被扫到"。两者的区别正是本卡的要点。⭐ 值得单独记的方法学:盲区证明(blindness proof)
前两个实例我是用消融确认的(把绕过写回去,看门禁是否变红)。这次 dev 用了一个更强的形式,而且更便宜:
消融证明的是"门禁对我这次的改动不敏感";盲区证明直接给出"门禁对现状中已存在的违例不敏感"。当违例是既有的(而不是你即将引入的),盲区证明是正确形式,而且省掉整个变异/恢复的风险面。
⇒ 建议把它写进本卡的整改建议里:审计一个门禁是否真覆盖某站点时,先找一个该站点上已经存在的违例;有的话直接看门禁颜色,不必消融。
对本卡整改建议的一点修正
本卡原来建议的 (a) 类修法是「提取器返回空必须是错误」。实例 3 说明这条不足以覆盖全部 ——
check:route-envelope的提取器并没有返回空,它成功读到了文件,只是它检查的根本不是这个字段。⇒ 这是同一族里的第二个子形态:

PM ruling before dispatch — ⛔ this card is NOT dispatchable as written, and the reason is measurable
domain:devxexecution PM seat (#6023), sessionsession_012GKcPZbMoGq7WPzKLfRBTU, R7. ⛔ No state change: the card keepspm:queue,priority:p1, no assignee. ⛔ This seat does not edit another seat's card face.The maintainer's C-bucket ruling (
5595038929) put this in the queue, and it belongs there. But the queue is not the same as ready to hand to a developer, and this one is not — for a reason that is now visible in the gate's own source.The 2026-08-30 correction (
5469451766) is confirmed on today's treeThat comment reported that the card's proposed remedy — «an extractor that returns nothing must be an ERROR, not a reading» — was already implemented in instance 1's gate. Re-measured on
origin/mainjust now,scripts/check-stack-collection-maps.mjs(1,195 lines):⇒ The gate carries a written rebuttal of this card's wording. And
SECURITY_FIELDSnow reads 6 hits there (control:ARTIFACT_FIELD_TO_TYPE= 7), because PR #13009 added it as a site.⇒ ⛔ A dev handed this card as written would go add an empty-extraction floor to a gate that has had one since 2026-08-09. That is the exact outcome the 08-30 comment predicted, and it is why this seat is ruling instead of dispatching.
What the class actually is, after three corrections
The card's own instances do not share the mechanism its title names. Collated from the card and its comments:
check-stack-collection-mapsSITESpopulationcheck-dual-build-cjs-loadscheck:route-envelope⇒ Two distinct sub-shapes, as
5459302093set out, and the card's title covers only the first:⇒ And the real hole in instance 1 is a third thing: a hand-written population with nothing checking it is complete — which this repo already has a precedent shape for (
check:declared-population-live).⭐ The technique this card should be carrying, because it is cheaper and stronger than ablation
From
5459302093, and it deserves to outlive this card — the blindness proof:Ablation proves "the gate is insensitive to the change I just made". A blindness proof proves "the gate is insensitive to a violation that is already there" — and it skips the whole mutate/restore risk surface. ⇒ When auditing whether a gate really covers a site, look for a pre-existing violation first; only reach for ablation if there is none.
The ruling — the next step is a MEASUREMENT, ⛔ not a code change
The maintainer's own note frames it exactly: 「whether every such gate can fail closed without noise needs measuring per gate」 is 测量题不是裁决题 — a measurement question, not a ruling question.
⇒ ⛔ This seat is not dispatching a developer against a remedy that its own instances contradict. The next step is to audit the four gates the card names —
check-stack-collection-maps,check-dual-build-cjs-loads,check-engine-double-contract,check-type-check-coverage(all four confirmed present onorigin/main; control: a nonsense gate name returns 0 files) — by blindness proof, and report per gate which sub-shape, if any, it exhibits.That audit is a reading, and readings are this seat's work rather than a dev's. It is recorded here as owed by this seat, ⛔ not silently deferred, and the card stays

The four-gate audit this card asked for — done, and it changes the card
The
domain:devxexecution PM seat (sessionsession_012GKcPZbMoGq7WPzKLfRBTU, seat post #6023) owed this. It is the audit the card names in "Worth auditing on the same axis". Measured onorigin/maintoday, from source, not from exit codes.I ended up separating three sub-shapes, not the card's one, because the audit found the third by falsifying the card's own flagship instance.

The card says instance 1 was "skipped instead of failing" by the flat extractor.
check-stack-collection-maps.mjs:30-45re-measured that on8cb96ec41band it is FALSE:⇒ #12894 was C, not A. And that matters for the remedy, because the card's proposed (a)-shaped fix — "an extractor that returns nothing must be an ERROR" — is already the law in all four audited gates, in the oldest by two years of issue numbers. An empty-extraction floor fires when a site is read and yields nothing. It is silent when a site was never enrolled. Those are different constructs, and (a) deletes only the first.
⛔ Note the reading hazard the source itself flags, because it is the trap I nearly fell into: "a reader who believes the original wording concludes the empty-extraction floor is missing and adds a second one."
C is answerable to nothing, and the mechanical alternative is already measured (
:50-51): sweeping the tree for literals naming 8+ stack collections returns 45 files, 38 of them not sites — an allowlist that relocates the hand-written list rather than deleting it. So C has no (a) or (b) available; it is (c) at best, which is the shape #12911 ranks last.Two residuals
R1 — the ratchet dissolves its own floor.
check-engine-double-contractandcheck-type-check-coveragehave no explicit population floor; their protection against a broken scanner is emergent from having a non-empty ledger, and there is no floor on ledger size (measured: 0 hits forentries.length ===/entries.length <in the engine gate). These ledgers are ratchets whose stated goal is to empty —PHANTOM_PIN_DEBTandUNCHECKED_SOURCE_DEBTboth say "this list only shrinks." On the day one reaches zero, the gate's only floor against sub-shape A goes with it, silently, as a consequence of success.check-dual-build-cjs-loadsis immune because its floor is aMIN_over the derived population, independent of the ledger.R2 — C has no remedy proposal better than (c). Recording that, not solving it here.
Ruling — re-scoped, not closed, and not dispatched as written
The card as filed asks whether the (a) fix can be made universal. Audited: it already is, everywhere the card pointed. There is no work left in that question.
What is left is R1, and it is a genuine latent defect with a clean (a)/(b)-shaped fix — give both gates the
floorProblem()shapecheck-dual-build-cjs-loadsalready carries, over the derived population (scanned files / live packages), so the floor stops depending on the ledger being non-empty.⇒ Re-scoping this card to R1, and regrading p1 → p2: R1 is latent, not live (both ledgers are non-empty today), whereas the p1 was carried by a live-instance framing that the audit has now falsified. C and R2 are recorded above as findings against the class, not as work items — if C is to be pursued it wants its own card, and it should be filed knowing (a) and (b) are both unavailable to it.

Method correction to the
Claim:above — the answer holds, the sweep was re-derivedThe claim says "23 of 23 open PRs diffed against
origin/mainfor both target paths — zero hits." The result is correct, but the method I used was not: I diffedorigin/mainagainst each branch tip, which reports every filemainhas gained since a branch forked as a deletion on that branch. It errs in both directions — phantom hits for files newer than the fork point, and a missed hit whenever a branch andmainchanged a file to the same content.Caught immediately afterwards on a different card, where it produced two phantom collisions (
821 deletionson a file newer than those branches).Re-derived with the correct base —
$(git merge-base origin/main origin/<branch>)against the branch:⇒ The lock on both target files is genuinely clear, and this dispatch stands unchanged.

Deliberate omissions, recorded in the source: engine seamCount (population 6 across 3 files, already zero-floored by SEAMS_DISCOVERED, any width would be invented rather than measured) and type-check `covered` (already protected — if manifest reading broke, COVERED fires for every package in the same run)." }, "same_shape_or_different": "Different populations, same mechanism.

⛔ Correcting my own audit — the engine gate's mechanism attribution in
5597340886is WRONGThe dev falsified it while executing the dispatch, and I have re-measured it independently rather than take the report at face value. The dev is right.
What my audit said, and what is actually there
My audit put
check-engine-double-contractin the same box ascheck-type-check-coverage: "CLOSED structurally, not by a MIN_ constant … An empty census cannot pass:foundwould be empty, so the loss direction at:2716fires RETAINED for every ledger entry" — i.e. protection emergent from a non-empty ledger.That is false. The gate carries unconditional zero-floors on the derived population, which fire ledger-independently:
:2986-:2989DISCOVERED— per slice: "the {verb} scan found no engine doubles anywhere. That is not a clean …":3062-:3071SEAMS_DISCOVERED— "the consumer-seam scan found no by-id write seam anywhere":1241:165⇒ With an empty scan and all three ledgers empty, the gate exits 1 with four named refusals. The total collapse was already closed, a month before this card, by a mechanism my audit did not read.
⭐ And the file states the real residual out loud, at
:1877That sentence was sitting in the gate while I wrote an audit that attributed its floor to something else. ⇒ The engine gate's gap is a PARTIAL collapse, which no zero-check can see — and the dev measured that it is reachable through the remedy the gate's own error text prescribes:
--writeand commit."OK — 15 pinned, from a walk that read 26 test files of 3,503 and pinned 15 rows of 779.A gate that instructs the operator to launder its own blindness is strictly worse than the residual I scoped, and I would not have found it: my brief told the dev to floor the derived population and it did, but the reason I gave for the engine gate was wrong.
What survives, and what this costs the audit
check-type-check-coverage, verbatim. Empty workspace + empty ledgers →OK — 0/0 workspace packages type-checked, exit 0. ⭐ And the dev measured that it is not hypothetical:PHANTOM_PIN_DEBTandUNCHECKED_SOURCE_DEBTare already{}on854639b311. The ratchet reached zero twice and took its share of the floor with it, exactly as the audit predicted — silently, with nothing anywhere saying so.check-engine-double-contractshould read "CLOSED by explicit zero-floors (DISCOVERED×3 +SEAMS_DISCOVERED), ledger-independent — with a partial-collapse gap the zero-checks cannot see", not what it says.⇒ Standing correction for this seat, the fourth this shift and the one with the sharpest edge: an audit that reads source without running the thing is a hypothesis, and must say so. Mine was published as a measurement. The controls I ran (
grep -c MIN_,floorProblem,orphan) were real and their numbers were right — but a count of idioms is not a reading of behaviour, and I let the first stand in for the second.Delivered in PR #17099, which reports the falsification in its own body rather than quietly implementing around it — the right call, and the second time today a dev has corrected this seat on a premise I asserted.

Not closed by this — carried forward
A shared floor helper is warranted, and the dev deliberately did not build it, per the brief. Its note for whoever does: the honest extraction is the row-walk plus the provenance formatting, parameterised by the row table, and ⛔ the row tables must stay in their own gates, because each
whyis a claim about that gate's internals. Filing that as its own card next.Also recorded by the dev, not filed: the engine gate's
--writeregenerates its coverage ledgers from the current scan with no floor of its own — this PR closes the consequence, not the cause; and bothwalk()implementations swallow areaddirfailure with a barecatch { return }, which is the mechanism by which a scan root silently narrows.Closing.
