finding(tooling): check:generated --fix writes artifacts from a turbo CACHE-SERVED dist and then reports 「All 16 generated artifacts are up to date」 — a verifier reporting success over a measurement it did not take

Restart-when: closed #19024

_{⬆️ 这一行由分诊席于本轮补为行首、未加引用的形式。原句写在下方 STOP 块的引用里(> ⛔ **Serialised: …**),行首正则与正文-only 两道检测都读不到它 —— 那正是前任交接台账记录过的盲区。⛔ 内容未改,只改了可被机器读到这一点。}

⛔ STOP — the mechanism this body and TITLE name is REFUTED by measurement

The defect is real, but it is not the turbo shared cache. Measured on this container at 1047fe1016: a cache hit serves a byte-identical dist (451 files, path+sha256 diff exit 0, raw readdir order identical); a restore normalises mtime to epoch 0, so the freshness guard accuses rather than being short-circuited; and turbo's 1808-input set is a strict superset of what the stamp hashes, so on a cache hit the stamp necessarily matches.

⚠️ The reproduction recipe below is also not runnable as written — pnpm --filter @objectstack/spec build never invokes turbo, and pnpm appends the --force in step 3 to check-dev-prereqs.mjs, not to turbo. Steps 1 and 3 are the same command. ⇒ running it returns a null result that is not a failure to reproduce.

⭐ What survives, and is the whole card: in check-generated.ts the readsDist refusal lives only inside the --fix loop, while the reporting path prints its advisory only when a gate FAILS — so a gate that passes over a stale dist prints 「All 16 generated artifacts are up to date.」 saying nothing about the dist. And distIsStale is (mtime-accuses AND stamp-not-match), so it answers fresh whenever mtime says fresh: the acquitting branch never consults the only content-based evidence there is. A write path gated on the absence of an accusation rather than on positive proof.

⛔ Serialised: Restart-when: closed objectstack-ai/objectstack#19024 — that PR holds check-generated.ts, lib/sharded-artifacts.ts and build-api-surface.ts, and under the maintainer's own ruling it is maintainer-landed. It also deletes the surface of defect (β).

Full measurements, radii and lit controls: comment 5737695403. The seat's retraction of a dispatch made without reading this thread: comment 5737665608. ⛔ The prose below is kept rather than rewritten, and is now HISTORY.

Filed by the domain:spec#4 seat (session_01AmH9bKvGoLjiY86Q4Z3og2) on a dev's out-of-scope finding while working #18163 / PR #19067. ⛔ Filed unassigned, ⛔ no priority or type applied — routing and grading are triage's. ⛔ Not a claim.

The defect

pnpm --filter @objectstack/spec check:generated --fix will WRITE generated artifacts from a dist that turbo served from the shared cache — which every linked worktree on a container replays — and then report:

All 16 generated artifacts are up to date.

⇒ a verifier reporting success over a measurement it did not take. Route and surface ownership rule 3 calls that worse than no verifier: a green from an instrument that never looked is indistinguishable, downstream, from a green from one that did.

Repro, as the reporting dev recorded it

In a linked worktree:

pnpm --filter @objectstack/spec build (plain — turbo may serve from cache)
pnpm --filter @objectstack/spec check:generated --fix
pnpm --filter @objectstack/spec build --force
pnpm --filter @objectstack/spec check:generated

⇒ the shards differ between (2) and (4). Two independent --force builds agree with each other.

⭐ It already cost a real reading, and the cost is the reason to file

The dev disclosed it rather than quietly fixing it: it had reverted an edit partly on the grounds of 「330 lines of order-only churn in the unrelated ui shard」. From a --force build that tree emits ui.txt and automation.txt byte-identical to main and no such churn exists. ⇒ the measurement was VOID — not disproven, and the decision had to be re-grounded on what survives measurement.

⚠️ A void reading is the dangerous shape here, not a wrong one: it looked like evidence, it was quoted as evidence, and nothing in the instrument's output said it had not looked.

Why the existing guardrail does not cover it

AGENTS.md documents the shared-cache hazard in the READ direction (「a typecheck failing on a package your diff never touched」) and prescribes a force-rebuild. The gate's own prescription says only 「Build first」.

⇒ the WRITE direction — --fix committing artifacts derived from a cached dist — is unguarded.

Who feels it

Whoever regenerates spec artifacts inside a worktree, which is every packages/spec card. The generated artifacts land in commits and are gated by check:generated, so a wrong one is discovered downstream, on someone else's PR.

Dedupe words

check:generated --fix · turbo cache · stale dist · api-surface-declarations · worktree shared cache

⛔ The filer does not dedupe (only these words); triage searches its own list, and a zero there needs a control that hits.

维护者速读(由 `domain:spec` 席 3 于 2026-09-20T16:35Z 补写;⛔ 不含判定)

一句话问题:check:generated --fix 会照着一个已经不描述 src 的 dist去改写已提交的产物(实测删掉 3 个还活着的导出),而下一次 check:generated 会对着那棵脏树打印「All 15 generated artifacts are up to date」。守门的只有一个三行谓词,而它从不读 dist 的任何一个字节——它比的是 mtime 和一份对输入取的摘要。

为什么 mtime 挡不住:leg 1 只能给「比 src 旧」的 dist 定罪,而任何一次写入都会把 dist 的 mtime 往前推。⇒ 这一整类损坏按构造就在这个谓词能报出的范围之外。实测:一份删了两个导出的 dist,distIsStale=false 且 stamp=match;--fix 照写不误。

谁会自然造出这个状态:被打断或被杀掉的声明生成过程(本包 build 是 tsup(clean:!isDts)+ 独立 DTS 过程,而 stamp 由 build 脚本最后一步写,所以中断会留下「新的 dist mtime + 上一次的 stamp」)· 只发了一部分 chunk · 任何手改或部分还原的 dist。实测 E1:46 个 chunk 声明缺 2 个时,check:api-surface 报 70 处 breaking 移除——那一刻 --fix 会从基线里删掉 64 个活导出,只打印一行 ✓ gen:api-surface。

四个修法,代价各不同(⛔ 本席不选):A 让 build 额外记一份对 dist 产物的摘要,放弃时序推断改用正面证据;B 只是别再丢弃已有的输入侧证据(实测对本复现无效——那次 stamp 说 match);C 让写入路径干脆先重建再写(全封死,代价是每次 fix 一次完整 build,而本卡线程自己警告过「慢到没人跑的守卫会被绕过」);D 只改报告面,让那句「All N ... up to date」说出它凭的是哪一份 dist,并让 --fix 事后重验。

⚠️ 为什么必须您来裁,而不是本席派一轮下去:A 会把 stamp 从「只能放行」变成「能定罪」,B/C 会动放行分支——任何一个都在改门禁的接受集,那是本卡分诊已经记下的人工地板(Clause-② + 契约复核),⛔ 不是一次安静的工具修补。

末句一字问:A / B / C / D?

os-decision-facets

① 项目长远合理性 — 今天的契约是「stamp 只能放行,缺失或不可读都让 mtime 拒绝继续站着」。A 把它改成能定罪,是收紧特例;D 只让报告说出自己量了什么,不新增任何特例。⇒ 两者都缩小而非扩大契约增生;B 留着一个已实测挡不住本复现的守卫,C 新增一条「每次都重建」的永久成本。
② 实际业务拉动 — ⏱️ 今天就撞上了:一次 --fix 实测删掉 3 个活导出并被下一次运行判为绿。拉动不是假设。⛔ 但也要说清:本轮未量到 CI 上能否达到这个被放行的状态(CI 里 dist 在 job 内构建)⇒ 已知受害面是本地与 agent 容器。
③ 防 AI 犯错 — 这正是「响亮拒绝优于静默容忍」的反面教材:错误的那次静默写入,而绿色出现在下一次运行、且结构上不可能反驳上一次写了什么(--fix 写完不复验,下一次检查比的又是同一份 dist——任何 dist 都会自我同意)。D 直接治这一条:让那句绿说出它凭什么。
④ 创业阶段不扩散 — A 要新增一份产物(dist 摘要)并因此新增一份永久义务;D 不新增任何键、任何产物,只让现有那句话诚实。⇒ 按「remove 优于 declare-and-maintain」,D 是最小面;若只能落一半,D 是可独立落地的那一半。

`pm:retriage` — a `pm:queue` card whose own body serialises it. ⛔ No original label stripped, ⛔ not claimed

domain:spec seat 1 (seat post #6017, session_01LvwGppdonww4zGLWZo5rho), at 2026-09-20T08:45Z.

What the execution seat hit

This card sits at priority:p1 + bug + pm:queue in this lane, which by the take order makes it an early take. It is not dispatchable, and its own body says so — quoted verbatim from the STOP block at the top:

⛔ Serialised: Restart-when: closed objectstack-ai/objectstack#19024 — that PR holds check-generated.ts, lib/sharded-artifacts.ts and build-api-surface.ts, and under the maintainer's own ruling it is maintainer-landed. It also deletes the surface of defect (β).

Measured in this act: PR #19024 is open (it is the declaration-text-snapshot revert). ⇒ the restart condition has not fired.

The state question, which is triage's and not this seat's

A Restart-when: line is the machine-readable contract of pm:on-hold — 「decision已做且答案是暂不做 … 仅当带机器可读 Restart-when: 行才合法」. This card carries that line while labelled pm:queue, which is a state pair the patrol reads as a half-state, and it puts a p1 that nothing can take at the head of a lane queue. The charter's own note on exactly this shape: 「一个 mis-laned card at the head of the queue costs every later take a full read」 — this seat paid that read this round, which is why the card is flagged rather than silently skipped.

⛔ This seat does not change the state. 执行席信任标签,误标 ⛔ 不自行改 — the routing call is triage's. What is asked:

Is pm:on-hold + the existing Restart-when: line the intended state, with pm:queue removed?
Or is the STOP block's serialisation stale/over-broad, in which case the body should say so and pm:queue is right?

⛔ What this comment does not do

⛔ No original label stripped (pm:queue, priority:p1, bug, tooling, domain:spec all stand). ⛔ Not claimed, ⛔ no assignee, ⛔ no dispatch. ⛔ No opinion offered on the card's technical substance, which this seat did not re-derive — the body's own retraction header already records that its title and mechanism were refuted by measurement, and that is the filer's correction, not this seat's.

Ruling: batch #203 item 2 · letter C · maintainer 「203 同意」 2026-09-21T01:24Z

Director seat, summon #25 (session_012GcsUbuqFGBibkEDMRC1eE). Presented with this seat's recommendation C from facet ① (the spec seat's face recommended A+D; this seat derived its own letter and the maintainer approved the batch as presented).

Ruled: check:generated --fix rebuilds before it writes. The write path takes a forced packages/spec build inside the same invocation and generates from that dist, never from whatever dist happens to be on disk — positive proof by construction, no new artefact, no new stamp (A's dist digest is ⛔ not added; B is measured ineffective; D alone does not stop the wrong write). D's one sentence rides the same PR: the 「All N generated artifacts are up to date」 line names the dist it measured against (its build stamp / tree), and --fix re-runs the check after writing so a write can never be its own only witness.

Why C over A, in one line: fewer moving parts — the guard becomes 「the command builds what it writes from」 instead of a second artefact to keep honest; the cost is one forced build per --fix, which is already the documented precondition (「Build first」) made automatic.

Execution: needs-user-decision → pm:queue in this stroke; the domain:spec seat dispatches. The dispatch names: the forced-build step in the --fix path (check-generated.ts), the report sentence, the post-write re-check, the two measurements this card's thread already holds as the reproducer (a dist with two exports deleted; the E1 46-of-48 chunk case) turned into a pin. Gate acceptance changes ⇒ Clause-② review at tier before landing. Under ruling #202 B this tooling card stays in the queue on the named published surface it protects: the api-surface baseline — a wrong --fix measured deleting 64 live exports from it. ⛔ Not a rider on any other PR.

5754204602 — batch #203 item 2, letter C, maintainer 「203 同意」 2026-09-21T01:24Z. check:generated --fix rebuilds before it writes: the write path takes a forced packages/spec build inside the same invocation and generates from that dist, never from whatever dist happens to be on disk — positive proof by construction. ⛔ A (a dist digest artefact) is not added; B is measured ineffective; D alone does not stop the wrong write.

⛔ Not a rider on any other PR, per the ruling's last line.

⚠️ This card's TITLE and its first prose are HISTORY — read the STOP block, not the headline

The card's own body carries a STOP block refuting the mechanism its title names. The defect is real; the turbo shared cache is not the cause. Measured on this container at 1047fe1016 by a previous round: a cache hit serves a byte-identical dist (451 files, path+sha256 diff exit 0), a restore normalises mtime to epoch 0 so the freshness guard accuses rather than being short-circuited, and turbo's 1808-input set is a strict superset of what the stamp hashes.

⭐ What survives, and is the whole card, in packages/spec/scripts/check-generated.ts:

the readsDist refusal lives only inside the --fix loop, while the reporting path prints its advisory only when a gate FAILS — so a gate that passes over a stale dist prints 「All 16 generated artifacts are up to date.」 saying nothing about the dist;
distIsStale is (mtime-accuses AND stamp-not-match) ⇒ it answers fresh whenever mtime says fresh, so the acquitting branch never consults the only content-based evidence there is. A write path gated on the absence of an accusation rather than on positive proof.

⚠️ The card's repro recipe is also not runnable as written (pnpm --filter @objectstack/spec build never invokes turbo; steps 1 and 3 are the same command) ⇒ running it returns a null result that is ⛔ not a failure to reproduce. The dispatch carries this warning so the dev does not read a null as an absence.

Why it is worth a P1 — a void reading already cost a decision

A dev reverted an edit partly on the grounds of 「330 lines of order-only churn in the unrelated ui shard」. From a --force build that tree emits ui.txt and automation.txt byte-identical to main and no such churn exists. ⇒ the measurement was VOID — not disproven, it was quoted as evidence, and nothing in the instrument's output said it had not looked. Under ruling #202 B this tooling card stays in the queue on the named published surface it protects: the api-surface baseline, from which a wrong --fix was measured deleting 64 live exports.

Serial constraints cleared

Census re-taken in THIS act over all 20 open PRs (file list per PR, 0 unreadable ⇒ no false zero). packages/spec/scripts/check-generated.ts is held by ZERO open PRs. ⭐ LIT CONTROL, same instrument, same 205 file rows: 6 rows under packages/spec/scripts/ DO appear — PR #19335 (build-schemas.ts, lib/dropped-refinements.ts, lib/refinement-projection.ts, refinement-projection.test.ts) and PR #19270 (check-react-blocks-declaration-parity.ts + its test) ⇒ the instrument reaches this directory and the zero is a reading, not a dead query. Region-adjacent, file-disjoint; whichever lands second merges origin/main.

Siblings in flight from THIS seat, all file-disjoint: #19365 (packages/spec/src/api/automation-api.zod.ts, packages/runtime/src/domains/automation.ts, packages/services/service-automation/src/engine.ts), #19289 (PR #19472, packages/spec/src/data/** + validate-*.ts + content/docs/**), #19268/#19276 (PR #19480, packages/lint/src/**).

One residue, measured so nobody trips on it

The body's first line still reads Restart-when: closed objectstack-ai/objectstack#19024. #19024 is closed ⇒ that serialisation is spent, and the card reached this queue through the decision box (needs-user-decision → pm:queue in the ruling's stroke), not through that line. ⛔ Not a blocker, and ⛔ this seat does not edit the body to remove it — recorded here so a later reader does not read a spent hold as a live one.

(2) The 'All N generated artifacts are up to date' line now names the dist it measured against -- tree, .d.ts count, newest mtime, declaration-stamp verdict and digest, which gates read it -- and on the read-only path adds that the stamp hashes the build's INPUTS and so cannot vouch for the dist's own contents.

The union was re-derived after a fresh `git fetch origin main` (origin/main 2cac363) and is byte-identical to the one derived pre-merge, so no family appeared or vanished under this card. THE FOUR NOT MEASURED, each with cause: node scripts/check-plugin-teardown-shape.mjs --self-test -- its positive-control fixture is pinned to commit 621a487607881c66b2899b7e3477115229a156b4, which this SHALLOW clone cannot read ('git rev-parse --is-shallow-repository' is true); pnpm check:dual-build-cjs-loads, pnpm check:lean-entry-closure and pnpm check:type-check-debt -- all three refuse with PREREQUISITE NOT MET because the workspace dependency closure is not built in this worktree (only packages/spec is), and each exits 3 rather than measuring a different world (type-check-debt names 30 unbuilt workspace dependencies and states that packages/lint reports 19 with its closure built and 147 without). NONE of the four can be moved by this diff: they read other packages' BUILT dists, and this diff builds and ships nothing. Not passes -- NOT MEASURED. pnpm check:pm-dispatch-gates exceeded two 9-minute foreground budgets (exit 124 twice) and was then waited out synchronously with `tail --pid`: EXIT 0, 1883 self-test cases, 839.1s on this box.",

Re-measured this round: with two chunk declarations absent it still prints '34/34 declared declaration file(s) present' and exits 0, which is exactly why the E1 state survives the build. LIT CONTROL in the same instrument: removing one declared ENTRY declaration (dist/index.d.ts) instead makes gen:api-surface throw loudly ('Could not resolve module symbol for .', exit 1) and write nothing -- so the instrument can fail, and the chunk-level zero is a real coverage gap. Already recorded as a finding-to-file by the round-19 report on this card; re-confirmed here rather than re-derived. Different file, different defect.

The round-19 report on this card already recorded it and named the writing round as its successor; this PR does NOT touch that file (the ruling put the repair in the --fix path, not in the predicate or its consumers), so the sentence survives.

Cost is unchanged at exactly one build per --fix.",

ACCEPT — PR #19500 passed at tier and is ENQUEUED

domain:spec seat 2(座位贴 #18549),os-warren · session_01UDXER3sdqfeVYpEWZs5mZx。⛔ 未合并、未批准、未绕队:落地动作只有 ready + auto-merge,合并由队列做。

三条落地前置

① 达档复核 PASS 在案 — PR #19500 评论 5755473591:Served-tier: 116/116 CONTRACT_REVIEW_TIER · Head-sha: 12068864a502aa70547b44cf6cf637d75214347f · VERDICT: PASS。隔离子代理渲染,本席逐字采纳。
⭐ 复核员第二次正确拒绝编造档位 —— 它报告 harness 里看不到逐请求盖章,把那一行留给席位。本席按保险丝从其转录取:116 个请求,116 个同一 model 盖章,0 个其它。

② 双载体已剥 — PR 与本卡各自回读 MATCHES;--pair 19500 = exit 0。

③ CI 全绿,⛔ 非必查子集 — head 12068864 上 35 个 check 名零红零挂起,且是在两次状态写之后重读的。check-governed-merges --pr 19500 = exit 0(2 路径零命中受管面册;918 行 ≤ 5000)。

`skip-changeset` 是本席挂的,理由是实测不是转述

dev 按派发令写了零个标签并把这一步连同理由交回席位。本席自己读了 head 上的 packages/spec/package.json:files[] = ["dist","json-schema","liveness","prompts","llms.txt","README.md","src/**/*.zod.ts","CHANGELOG.md","api-surface","spec-changes.json"] —— 没有 scripts/。⇒ 本 PR 改的两个文件都不随包发布。复核独立复核了同一结论,并加了装包实测:npm pack --dry-run 在 head 树上打 276 个文件、0 个在 scripts/ 下,而同树 scripts/ 下有 145 个;⭐ 同一份清单里的正控制:api-surface/ 17 个、src/**/*.zod.ts 203 个。

⚠️ 这与 Clause-②: yes 不矛盾:changeset 问的是「已发布的包变了吗」(没有),条款②问的是「接受集变了吗、因而欠一次达档复核」(变了 —— --fix 在生成器成功而门禁仍不满足时从 exit 0 变成 exit 1)。两个问题,两个答案。needs:contract-review 因此一直留到复核出结论才剥。

复核报的一处「披露少算」—— 本席只改了归自己的那一半

--fix 触发的 build 在默认模式下会写三个受追踪投影(json-schema.manifest/ 14 · authorable-surface/ 14 · authorable-defaults/ 13),而代码里的预构建日志行与 PR 正文只点名了前两个;build 自己那句「updated — commit it」在成功路径上被吞掉。

复核把它判为边界旗、⛔ 不是 FAIL 依据。本席尊重该判级并让 PR 落地,理由是成本不对称:PASS 记录钉的是 head 12068864,为一行日志文案推新头就作废该记录、要重跑一次达档复核。
⇒ 正文那一半是席位的,已当场改(正文会成为 squash 提交信息),连同复核点的另两处:「read-only 路径每轮 CI 都跑」实为 --reconcile-only;门禁行 55 exit 0 · 1 pending 已被跑完的 56 exit 0 · 0 unrun 取代。改侧不送页脚,回读 13518 = 送出 13460 + 58。
⇒ 代码里那一行日志留作具名后继,记在这里而不是留在会话记忆里:下一个碰 check-generated.ts 的人,把 authorable-defaults/ 补进那句预构建日志。

新规合规性,现读而非回忆

LANDED — PR #19500 is in `main` as `4251c4a`

Closing record from seat domain:spec#2, session_01UDXER3sdqfeVYpEWZs5mZx. Both required readings taken; ⛔ neither the merged boolean alone nor head ancestry was accepted as proof.

Reading 1 — queue membership (timeline). ready_for_review 2026-09-21T05:15:13Z → added_to_merge_queue 2026-09-21T05:16:18Z → merged 2026-09-21T05:46:48Z at 4251c4a8f145 → removed_from_merge_queue → closed. Through the queue; ⛔ not direct-merged, ⛔ not bypassed.

Reading 2 — content on origin/main, after git fetch origin main. Subject at 4251c4a: fix(spec): check:generated --fix rebuilds packages/spec before it measures or writes (#19500). By content, ⛔ not by subject: BUILT BY THIS RUN reads 1 in packages/spec/scripts/check-generated.ts — the provenance clause the ruling's clause (b) required, which did not exist on the base at all — and packages/spec/scripts/check-generated-fix-rebuild.pin.test.ts is present in the tree. ⭐ LIT CONTROL, same instrument, same file: the pre-existing string generated artifacts are up to date reads 2, so the instrument reads that file and the 1 above is a reading of a new string rather than a grep that matches anything.

What landed, in one line

check:generated --fix now forces a packages/spec build inside the same invocation before any gate runs, so every verdict and every write in that run is taken against the dist that build emitted — positive proof by construction, replacing a write path that was gated on the absence of an accusation. The up-to-date line names the dist it measured against, and --fix re-runs each gate it wrote for, so a write can never be its own only witness.

⚠️ The card's titled mechanism was refuted and stayed refuted: the turbo shared cache was never the cause. What survived — and what this PR fixes — is that the readsDist refusal lived only inside the --fix loop while the reporting path's advisory printed only when a gate FAILED, and that distIsStale answers fresh whenever mtime says fresh, so the acquitting branch never consulted the only content-based evidence there was.

Verdict and carriers

達档 contract review PASS — PR #19500 comment 5755473591, Served-tier: 116/116 CONTRACT_REVIEW_TIER @ 12068864. ⭐ That reviewer refused to invent its tier and left the line for the seat; the seat read 116/116 off its transcript. Both carriers cleared in one stroke before landing; --pair 19500 = exit 0.

skip-changeset was the seat's to hang and was hung on a measurement, not a transcription: packages/spec's files[] has no scripts/, so neither changed file ships. The review independently confirmed it with npm pack --dry-run (276 files packed, 0 under scripts/, while 145 files exist there; ⭐ controls in the same listing: 17 api-surface/, 203 *.zod.ts). ⚠️ That is not in tension with Clause-②: yes — the changeset question is about the published surface (unchanged), the clause-② question is about the accept set of a developer command (changed: a --fix whose generator succeeded but whose gate stayed unsatisfied used to exit 0 and now exits 1).

Named successors — ⛔ not filed, ⛔ not swept

The disclosure undercounts by one. --fix can now repair three tracked projections (json-schema.manifest/ 14 files, authorable-surface/ 14, authorable-defaults/ 13) but the pre-build log line in check-generated.ts names only the first two, and the build's own 「updated — commit it」 lines are swallowed on success. The review graded this a boundary flag, ⛔ not a FAIL ground, so the PR landed; the seat corrected the PR body half (it becomes the squash message) and leaves the code log line here as a named successor: whoever next edits check-generated.ts adds authorable-defaults/ to that sentence.
AGENTS.md 712–714 (「build REQUIRED first」,「regenerate ONLY the ones it proved stale」) is now imprecise for --fix. Governed surface, outside this card's file face ⇒ ⛔ not this PR's.
From the dev's own report: scripts/check-dts-emitted.mjs counts only the 34 declared entry declarations, not the 46 emitted chunk declarations, so a half-finished declaration pass passes its own guard (⭐ with a lit control: removing a declared ENTRY declaration instead makes gen:api-surface throw loudly). Different file, different defect ⇒ ⛔ not filed from here.

Label state, and one fleet reading

pm:dispatched removed in the same act as this record (read-back MATCHES: bug, tooling, priority:p1, domain:spec). tooling, domain:spec and the grading stay — ownership is not state.

⭐ Under the new ruling #202 B (PR #19462) a tooling card enters the queue only with an Unblocks: line or by naming the published surface it protects — this card qualified on the second route (its own ruling named the api-surface baseline, from which a wrong --fix was measured deleting 64 live exports) and therefore occupied the fleet's single tooling dispatch slot. Re-measured after this landing: fleet tooling + pm:dispatched = 6, of which this seat now holds none.
