[finding] the liveness gate has no reading of a retiredKey() tombstone — a tombstoned key's row may claim live and nothing objects (the mechanism behind #18304)

Reading taken 2026-09-18T14:59Z on origin/main@221dabb72; every grep below is git grep <PAT> origin/main -- <paths>, not the shared working tree.

Defect

packages/spec/scripts/liveness/check-liveness.mts classifies a schema property from two sources: the ledger row's status, and — for a property with no row — a MARKER read out of its description by markerStatus(). That function knows exactly two markers:

:468  experimental: /\[experimental|not enforced|aspirational/i,
:469  planned:      /\[planned|not yet implemented|coming soon/i,

There is no third arm, and no liveness script reads [REMOVED] at all. So the two removal routes are governed asymmetrically:

strict removal (the key leaves the walked shape) — orphans.mts fails the build on the ledger row left behind.
retiredKey() tombstone (the key stays in the shape as z.never()) — orphans.mts's own guidance requires the row to stay: "a retiredKey() tombstone KEEPS the key in the walked shape, so a tombstoned key's row must STAY — deleting it reports UNCLASSIFIED instead" (orphans.mts, ORPHAN_GUIDANCE). And nothing constrains what that row's status says. A tombstoned key may be graded live, carrying live evidence, indefinitely, with CI green.

That is a mechanism, not a hypothesis. #18304 is one measured instance of it: agent.tools was tombstoned in the spec and its only reader deleted in cloud, while agent.json graded the row live for three months and no gate objected.

Measurement

Instrument: git grep over origin/main@221dabb72; unit = occurrences.

reading	value
`[REMOVED]` read by any script under `packages/spec/scripts/liveness/`	0
lit control, same instrument, same corpus: `\[planned` / `\[experimental`	2 — both in `MARKER_RE` (`:468`, `:469`)
lit control that the marker is real: `[REMOVED]` in `packages/spec/src/*/.ts`	15
`retiredKey` identifier anywhere in the liveness family	2, both prose in `orphans.mts` — no import, no join
lit control on that: files importing `retired-key` under `packages/spec/src` + `packages/spec/scripts`	103

The tombstone mechanism is pervasive (103 importers). The one place that grades a key's liveness is the place that does not read it.

What would have made these numbers different

A single arm in MARKER_RE for the tombstone marker, or any import of retired-key from the liveness family, would have shown up in the first two rows. The lit controls rule out a dead grep in both directions — the corpus answers when a marker is read, and the marker exists to be found.

Evidence limit

Grep only, on one ref. What this does not establish: how many ledger rows are in the defective state right now. #18304 is one confirmed instance; the population is unmeasured, and measuring it is the first piece of the work — it needs exactly the join the gate lacks (walk the retiredKey() tombstones, ask each one's ledger row for its status). Do not read "0 readings of [REMOVED]" as a count of affected rows.

Dedup words

liveness tombstone status, retiredKey ledger dead, markerStatus REMOVED

Provenance

Out-of-scope finding from the os-dev report on #18304 (PR #19059), re-measured independently by the domain:spec#3 execution seat before filing; the controls and the origin/main anchoring are the seat's. Filed bare per the finding contract — grading, type and routing are the triage seat's production, not this seat's.

⛔ 本轮的第一交付物是人口数,不是补丁

卡面自己把话说死了,逐字:

What this does not establish: how many ledger rows are in the defective state right now. #18304 is one confirmed instance; the population is unmeasured, and measuring it is the first piece of the work — it needs exactly the join the gate lacks(走一遍 retiredKey() 墓碑,问每一个的账行 status)。

修法:⛔ 本席不选,分诊也不选 —— 但验收两条腿是同一个,且可机械判定

⇒ 你按实测选,并在报告里写清为什么。⚠️ 两形的副作用面不同(①动的是「没有账行时怎么推断」,②动的是「有账行时它允许说什么」)—— 那正是你要量出来的差别。

验收(分诊的原话,本席照抄并加一条):

⭐ 主体:构造一个 retiredKey() 墓碑 + 账行 status: live 的样本 ⇒ 门禁必须变红。
⭐ 亮控:同一个样本把 status 改成合法值 ⇒ 必须变绿。⛔ 少了这条就分不出「规则生效」与「规则根本没跑」。
⭐ 暗控(本席加的):一条普通的、非墓碑的 live 账行,在改前改后都必须绿,且判词不变 ⇒ 证明本轮没有顺手收紧别的东西。
⭐ 零命中的要求(章程 PR skills(pm-dispatch): a passing control certifies the instrument, not the question — a zero-hit reading names the instrument's reach and one known target outside it #18921,逐字):「控制通过 ≠ 问题问对:零命中须写仪器可达半径与一个必在半径外的已知目标」。

  "summary": "POPULATION FIRST, as ordered: the join the gate lacked says EXACTLY ONE ledger row is in the defective state today -- agent/tools, graded live on a retiredKey() tombstone. That is #18304's row, and open PR #19059 already flips it to dead. 79 tombstones are reached by the gate's walk, 78 already dead, and all 79 take their status from an explicit ledger row (0 from a marker, 0 from childrenDefault, 0 UNCLASSIFIED). Population is 1, so I proceeded rather than handing back -- but with a rider on the dispatch's assumption that a tiny population means the gate going red 'will not disrupt anyone': it does not disrupt anyone ONLY IF this PR lands AFTER #19059. On main's ledgers today the rule is red (check:liveness exit 1 on agent/tools, plus 16 pre-existing check-liveness.test.ts cases that assert green against a verbatim ledger copy, all 16 with that one cause). Simulated post-#19059 on a ledger COPY: green, with the gate's whole output byte-identical to the pre-change run except the two lines this PR adds. Remedy chosen by measurement: triage's shape (1) -- a third [REMOVED] arm in markerStatus() -- leaves the acceptance sample at exit 0 (measured, mutation proven on disk), because markerStatus() is only consulted when the row's status is falsy and it never is for any of the 79; it would only silence the UNCLASSIFIED failure a row-less tombstone already raises, which ORPHAN_GUIDANCE tells authors never to create. So shape (2): a pure scan in orphans.mts (scanTombstonedRows + TOMBSTONE_STATUS_GUIDANCE) wired into the gate's walk as a fourth direction. Forbidden set is the named constant ['live'], exactly as ruled -- planned/experimental/live-elsewhere on a tombstone are equally false but their population is 0 today, so widening it is its own measurement. Nothing under packages/spec/liveness/ was touched; no .zod.ts declaration changed; no ledger row deleted.",
  "tests": "ACCEPTANCE (real gate, --ledger-root against a copied ledger; the red and green samples differ in EXACTLY one status value plus the arithmetic state-counts.md requires, so a stale count cannot mask the verdict). MAIN LEG -- tombstone hook/timeout + row status live: BEFORE exit 0 (green: the gate had no reading), AFTER exit 1, 'x 1 TOMBSTONED key(s) whose ledger row still claims a forbidden status:' / the finding line naming hook/timeout as live. LIT CONTROL -- same sample, legal status: BEFORE exit 0, AFTER exit 0 with the summary clause present. DARK CONTROL -- ordinary non-tombstoned live rows: AFTER exit 0, and a full diff of the gate's output before vs after on that legal ledger differs ONLY by the new 'tombstoned keys:' census line and the new clause in the summary sentence; all 39 per-type verdict lines and every other check's output byte-identical (hook 22 classified (live 19, dead 3) on both sides). ABLATION DISCIPLINE: fix committed FIRST, then both files reverted to base 362035cc07 with git restore --source (tree only, never the index); mutation proven on disk (blob 5ece9b41 to 5e6cf354, scanTombstonedRows occurrences 2/1 to 0/0); restore proven by `git diff HEAD` empty, `git status --porcelain` empty and the blob hash equal to HEAD's; an EXIT/INT/TERM trap restored from HEAD on every leg, absolute paths seeded from git rev-parse --show-toplevel. Remedy-(1) variant measured the same way via scripts/ablation-replace.mjs --expect 1 (anchor 1 to 0, replacement 0 to 1, blob moved): exit 0 on BOTH samples. NO DIST LEG NEEDED AND NONE TAKEN: check-liveness.mts imports ../../src/** and runs under tsx, and this worktree has NO packages/spec/dist at all (ls packages/spec | grep -c dist = 0), so the PM's stale-dist trap has no surface here -- stated rather than assumed. CENSUS INSTRUMENT DRIFT CONTROL: the census walk reproduces check:liveness --json's classified+unclassified for all 39 types and 1092 verdict points exactly (0 mismatches), so it is the gate's walk, not a copy of it. UNIT: vitest scripts/liveness/orphans.test.ts -- 22 passed (incl. TOMBSTONE_MARKER held equal to what retiredKey() actually writes, read from the producer). GATE-LEVEL: the 5 new #19062 cases in check-liveness.test.ts pass. FULL AFFECTED DIRECTORY: vitest run scripts/liveness/ -- 313 passed, 16 FAILED, all 16 the pre-existing 'green against a verbatim copy of the shipped ledgers' controls, all 16 naming agent/tools as live and nothing else (failure count 16 == occurrences of that string 16; every failure's assertion shape is the exit-code one).

PM 复核 — 卡 #19062 / PR #19092

结论:实现接受;⛔ 但现在不入队。 阻塞不是判断,是我自己量到的一条红线 —— 详见下文第 3 节。

下面每一条都是我在本地/GitHub 上自己重新量的,⛔ 不是复述 dev 报告的叙述。取数时刻 2026-09-18T18:28Z–18:34Z,判读的 PR 头是 a5fcbebbbb2c3c2ba9d6813bc70d76ae6d1e90c9,当时的 origin/main 是 07c6f822edd9c4c48a7ce34767de420c6096b9c3(2026-09-18T17:49:30Z)。

1. 总体数(79 / 78 / 1)我重新量了一遍,而且是点名量的,不是计数

报告说「79 个墓碑、78 个已 dead、1 个违规」。计数在这条车道上翻过车(范围本身就是被问的东西时,计数不是读数),所以我没有停在数字上,而是让闸门把名字吐出来:把 post-#19059 台账副本里所有 dead 行一次性翻成 live(160 行),再跑闸门 —— 它点名列出了 79 个被 walk 触达的墓碑坐标(field/conditionalRequired、flow/template、…、connector/health.circuitBreaker.monitoringWindow),agent/tools 在其中。

拿这 79 个坐标回头去读 post-#19059 的台账,逐个解析状态:

POST-19059 status tally over the 79 tombstoned keys: {"dead":79}
rows my walker could not resolve: 0

「0 个解析不出来」这一行是本次读数的健康信号:如果我的解析器走错了形状(这条车道最常见的坏仪器形态),它会以「解析不到」的方式暴露,而不是安静地给出一个像样的错数。

2. 四条腿 —— 主腿、修复腿、暗控、枚举腿

腿	台账	闸门	结果
A 主腿	今天的 main	PR #19092 的闸门	`exit=1`,`✗ 1 TOMBSTONED … agent/tools -> "live"`,`79 … 78 … 1 FORBIDDEN`
B 修复腿	main + #19059 的三个台账文件	同上	`exit=0`,`79 … 79 graded with a status the tombstone allows`
C 暗控	B 的台账,另把 `hook/timeout` 翻成 `live`	同上	`exit=1`,点名 `hook/timeout`,`78 … 1 FORBIDDEN`
D 枚举腿	B 的台账,所有 `dead` 翻 `live`	同上	`79 FORBIDDEN`,逐个点名

腿 C 是判别性的那条:它证明这条规则不是围着 agent/tools 写死的一次性判断 —— 换一个墓碑,闸门点名换成那一个。腿 A 与 CI 上 Spec property liveness 的失败逐字一致,说明我的本地装置和 CI 读的是同一个东西。

⚠️ 一条坏仪器要记下来,免得下一个人把它当结论:我第一次做暗控时挑的是 mapping/transform,探针打印 NOT FOUND —— mapping.zod.ts:93 确实有 retiredKey,但 mapping.json 的 props 里没有这一行(台账 _note 自己写了那些行是被 DELETE 掉的)。那一轮的 exit=0 什么都没测到,是「探针没够到槽位」而不是「规则不响」。换成 hook/timeout 才成立。

3. ⛔ 落地顺序:这不是预测,是现在就红着的两个 check

dev 报告里对我派发词的那条回驳我接受:我派发时写的「population 小到不会打扰任何人」只在 #19092 排在 #19059 之后时成立。我去 GitHub 上核了 PR #19092 头上的 check,以及本地把测试跑了一遍:

Spec property liveness —— failure。job log 逐字:✗ 1 TOMBSTONED key(s) … agent/tools -> "live"。
Test Core (1/6) —— failure。本地复跑 check-liveness.test.ts + orphans.test.ts:Tests 16 failed | 69 passed (85),16 个全部、无一例外地指向同一个 agent/tools 成因(16/16 的失败块同时出现 TOMBSTONED key 与 agent/tools);orphans.test.ts 新增的单元腿 22 条全绿。

这 16 条不是写死的 fixture:check-liveness.test.ts:92 是 cpSync(LEDGERS, …) —— 它把真台账目录整份拷进临时目录再逐例改。所以 #19059 一落,这 16 条自己就绿了,不需要在本卡里动它们。

⭐ 一条自纠,给下一个读这条车道的人。 我原本准备照常用 ALLOW_UNSTABLE=1 的口子处理「非必过 check 红」。在这张卡上那是错的:Spec property liveness 不在 7 个必过 context 里,真正把队列按住的是 Test Core。也就是说 —— 如果 #19092 只红了 Spec property liveness,mergeable_state 会是 unstable,而我那条「红的是 advisory」的默认口子会放它进队,把 main 弄红。这次是 Test Core 同时红了才兜住的。这个口子的判断永远要落到具体那条红上,不能按 required/非 required 一刀切。

4. 两个待决问题的答复

Q1 落地顺序 → A(仅靠布防顺序,不折叠、不交接)。 依据就是第 3 节:约束已经被 CI 强制了,不是靠谁记得。队列对每个条目都是「merge 到当时的 main 上」重建的,所以 #19059 的 squash 一上 main,#19092 在队列里重建时就带上了修好的台账。B(交接)多一次手递手而不多买任何保障;C 已被分诊逐字排除(「不折叠」),而且会让 #19059 的 diff 被两张卡管。

Q2 禁止集保持 ['live'] → A(保持)。 依据是第 1 节那张表:post-#19059 的 79 个墓碑行全部是 dead,{"dead":79}。也就是说把禁止集扩成 ['live','planned','experimental','live-elsewhere'],今天会多抓到的行数是 0。⛔ 扩宽在今天没有任何证据支撑它 —— 这正是它应该是一个具名常量而不是内联比较的理由,代码里 TOMBSTONE_FORBIDDEN_STATUSES 连同那段「widening this set is its own measurement」的注释,把「今天不扩」和「将来要扩得先量」两件事分开写清楚了,这个做法我接受。

5. 这两个「零」的仪器半径,以及必在半径外的已知目标

「0 行会被扩宽的禁止集多抓到」这个零,半径是:PR #19092 的 walk 在 post-#19059 台账副本上触达的那 79 个坐标,跨 packages/spec/liveness 下全部台账文件。半径外确实有已知目标,点名两个:

闸门自己那一行输出说,有 114 container entr(ies) carry a blanket verdict over 601 child key(s) that are classified NOWHERE —— 盖在 blanket verdict 下面的子键,walk 不逐个落到,那底下若有墓碑,这个零看不见它。
MAX_DRILL_DEPTH = 8 以下的东西同理。

6. 一条半径外的观察 —— 记录,⛔ 不立卡

TOMBSTONE_MARKER = '[REMOVED]' 的反腐化测试(orphans.test.ts,import 真正的 retiredKey() 再断言 description 含这个标记)方向完全对。但本仓里写出同一个标记的函数有两个,不是一个:

packages/spec/src/shared/retired-key.ts:107   .describe(`[REMOVED] ${guidance}`)   ← 被钉住的那个
packages/spec/src/ui/component.zod.ts:379     .describe(`[REMOVED] ${guidance}`)   ← retiredComponentProps,没被钉住

第二个是元素粒度的退役(整个 props bag 被 z.never 拒掉,user:profile / #14159),而且它不带 .optional()。

⛔ 我不为它立卡,理由是量出来的而不是判断出来的:component 不在闸门 walk 的 39 个受治类型里,枚举腿列出的 79 个坐标里也没有任何一个来自它 —— 也就是说它今天整个在仪器半径之外,population 是 0。把半径外、零 population 的东西立成活儿,是把推测当工作。记在这里,是因为哪天 walk 钻进 page component props,这条钉子就只钉住了两个生产者中的一个。

顺带一提:本仓另一处 datasource-credential-redaction.ts:284 读同一个标记用的是 .startsWith('[REMOVED] ')(带尾空格),而本 PR 用的是 includes。两个生产者今天都把标记写在开头,所以今天两者等价,不是缺陷;只是比本仓已有的先例松一点,记录在案。

7. 处置

⛔ 不入队,直到 fix(spec): the agent.tools liveness row says dead — it claimed live on a key the schema tombstoned #19059 的 squash 出现在 fetch 过的 origin/main 上。这是一条量出来的阻塞,不是等待:上面第 3 节就是它的读数。
fix(spec): the agent.tools liveness row says dead — it claimed live on a key the schema tombstoned #19059 是 [finding] agent.json grades agent.tools as live, but the spec retired the key and cloud deleted its only reader — the row the stale-path exemption hid #18304 的落地,挂在 os-elon-musk 名下,当前 clean、7 个必过 context 全绿、ready_for_review 自 2026-09-18T15:20:11Z。⛔ 它不是我这个座位的落地,我不碰它、也不去催它 —— 我只记录 feat(spec): the liveness gate reads the retiredKey() tombstone marker — a tombstoned key may not be graded live #19092 在等它。
fix(spec): the agent.tools liveness row says dead — it claimed live on a key the schema tombstoned #19059 一上 main,我 rebase/merge 本 PR 后按常规三腿复核再布防。

半径补记 —— 给本卡上本席那份「79 个墓碑」读数加一个具名的、半径外的已知目标。 取数时刻 2026-09-18T20:43Z

本席在评论 5734529983 里写过:walk 触达 79 个 [REMOVED] 墓碑,#19059 落地后 79 个全部 dead,并声明了半径(那 79 个坐标)与两个半径外的已知目标(blanket verdict 覆盖的 601 个子键、MAX_DRILL_DEPTH = 8 以下)。

⇒ 现在有第三个,而且是具体的、已量到实例的:

通过 .strict() guidance-map 路退役的键,根本不在 walked shape 里留 [REMOVED] 墓碑 —— 于是 walk 与台账两边都看不见它。本席 ⏱️ 2026-09-18T20:43Z 在 origin/main 上第一手复核:

packages/spec/src/ai/tool.zod.ts:36   const TOOL_RETIRED_KEY_GUIDANCE: Record<string, string> = {
packages/spec/src/ai/tool.zod.ts:154    guidance: TOOL_RETIRED_KEY_GUIDANCE,

该文件里 [REMOVED] 与 retiredKey 一条都没打印出来;亮控:同一把探针在 packages/spec/src/ai/agent.zod.ts 上读到 retiredKey 4 处 ⇒ 探针看得见墓碑,上面的零是读数。台账侧 tool.category 与 tool.active 连行都没有((NO ROW))。

⚠️ 这不是说那个 79 错了 —— 它答的是一个比读者可能以为的更窄的问题:「walk 能触达的墓碑里,有几个行状态违规」。它答不了「这个仓里有多少键已退役」。

已另立 #19118 承载这条发现本身(它同时给 #19093 刚落地的那份七元组普查划了同一条半径)。这条补记只做一件事:把那个具名目标挂回本卡的读数旁边,免得下一个引用「79」的人把它当成全集。

⛔ 原读数一字未改;本条不是重新测量。

  "summary": "Fixture repointed; head is now 3d49d7a199 and the whole liveness suite is 333/333 green, gate included. ONE CORRECTION to the coordinator's reading, which does not change what had to be done: the guard did not fire on the red sample's flip. It fired on the BASE builder's flip. The old sample() neutralised the then-offender with setStatus(root,'agent','tools','dead'); once #19059 made that row dead upstream, that flip became the no-op -- which is exactly what the message says ('is already \"dead\"'). The red sample's own carrier was hook/timeout and it was never the problem. So the rot was in the half that existed only to paper over one row, and the fix removes that half outright rather than re-aiming it. The guard is kept, not weakened, and is now backed by a stronger form: the derivation REQUIRES a carrier whose row is currently dead (the only status from which a flip to live is a real state change) and asserts it, and a new case proves the red and green samples differ in exactly one value and nothing else -- a byte-level version of the claim the old guard made one row at a time. The carrier is no longer named. It is derived per run from the gate's own enumeration under filters that are properties of the SHAPE rather than of today's verdicts: top-level (the writer edits props[key], not a children path), not a BOUND_PROOF_PATHS coordinate (a bound class graded live demands an ADR-0054 proof, which would give the red run a second cause), and currently dead. To make that possible the scan now ENUMERATES its population instead of totalling it -- report.tombstones, on report.authorable's stated reason (#18133): a population that is only counted cannot be checked by anything downstream. WHY IT CANNOT ROT THE SAME WAY: it is not a name, so a carrier that leaves the population is replaced by the next one with no edit; the filters are structural; and the only remaining failure mode -- the population emptying or every member becoming ineligible -- fails the derivation case loudly with both numbers printed, instead of turning a sample into a silent no-op. Residual hostage, declared rather than hidden: the green legs still need the shipped ledgers to be green overall. That is not new and not mine -- it is the dependency this file's very first control case ('is green against a verbatim copy of the shipped ledgers') already states. I chose to inherit it rather than carry a private patch list, because a private patch list is precisely the thing that just rotted.",
  "tests": "PER-CASE, on the coordinator's head 30e1eacd38 (BEFORE) versus 3d49d7a199 (AFTER). 'FAILS when a tombstoned key's ledger row claims live': RED (agent/tools is already dead -- the sample would be a no-op) to PASS 2008ms. 'is GREEN on the same sample with a legal status -- one value apart': RED (same cause) to PASS 2019ms. 'leaves ordinary live rows alone -- the per-type verdicts are unchanged': RED (same cause) to PASS 4235ms. 'reports how many tombstones it reached, not only how many were forbidden': RED (same cause) to PASS 2127ms. 'derives its carrier from the gate's own tombstone enumeration': NEW, PASS. 'builds the red and green samples one value apart, and nothing else': NEW, PASS. Block total 6 passed / 0 failed. FULL SUITE vitest run scripts/liveness/ -- 12 files, 333 passed, 0 failed (was 313 passed / 16 failed before #19059 landed). check:liveness against the REAL ledger: exit 0, 'tombstoned keys: 79 tombstone(s) reached by the walk, 79 graded with a status the tombstone allows'. 0 failure blocks name TOMBSTONED key. The ordering held exactly as measured last round. DERIVATION FUNNEL, printed not counted: 79 enumerated by the gate to 42 top-level to 42 unbound (BOUND_PROOF_PATHS holds 26 coordinates; 0 of them collide with a tombstone today, so the filter excludes nothing now and is there for the carrier that lands on one later) to 42 currently dead; sorted first = action/bulkEnabled. 42 eligible candidates means the choice is real, not a survivor. ABLATION -- can the repointed fixture still go red? TOMBSTONE_FORBIDDEN_STATUSES neutered from ['live'] to [] via scripts/ablation-replace.mjs --expect 1 (anchor 1 to 0; the neutered spelling counted 1 and the original 0 on disk; blob ddabc5e3a3da to 32064dcee2e3). Result: EXACTLY ONE case fails and it is the main leg, 'FAILS when a tombstoned key's ledger row claims live' -- 1 failed / 5 passed. The five controls correctly stay green: with nothing forbidden the sampled tree really is legal, so a control going red there would mean the control was measuring something else. Restore proven: blob back to ddabc5e3a3da, equal to HEAD's blob, git status --porcelain empty; an EXIT/INT/TERM trap restoring from HEAD wrapped the whole leg.

Successor: whoever next widens this file's control set.",
