[finding] two census figures in the proof-4 prose of build-schemas.ts are measured wrong — the PR body's 258 names a different population (147), and the docblock's "7 of the 8 defs are unions" is 3 of 4 #18579

   要收的东西:三个一行的更正(可能再加一个夹具)

   build-schemas.ts proof-4 那段散文里有两个普查数字测错:

   1. PR 正文那行「defs resolving to exactly one declaration that names an undeclared key: 258」—— 实测 147。⭐ 258 是「解析到恰好一份声明(不论它有没有点名任何东西)」的计数 ⇒ 标签与数字来自两个不同的总体。(该分区其余:ambiguous 0 · empty-shape 6 · no-shape 303。)
   2. docblock l.1440-1441 的「7 of the 8 defs in that state are unions」—— 实测该状态是 9 个键落在 4 个 def 上,其中 3 个是 union。

   ⭐ 两处支撑的那个论断本身仍然成立(union 在 not-delivered 集里占多数:4 个 def 里 3 个、9 个键里 7 个)。错的只是算术。

   ⚠️ 先重测,再动笔

   卡面明写(⏱️ 该读数是复核席的,上界取立卡时刻 2026-09-17T03:00Z;⛔ 本席未重推普查):那些数字取自分支 9e0324f807,而 packages/spec/src 在 main 上已经动过(expression.zod.ts、translation.zod.ts)⇒ 普查会漂。

   ⇒ 你的第一步是用该 head 自己那份逐字函数把整份普查重推一遍,拿到当前的数字再改。⛔ 不要把卡面的 147 / 3 of 4 直接抄进代码 —— 它们也是别人在别的树上的读数。

   ⭐ 卡面那份复核之所以可信,靠的是「除这两个以外每一个数字都复现了」(1525 / 1117 / 779 / 770 / 9 / 2,以及旧 head 的 144 与 772)。⇒ 验证仪器的是「其余全对上」,⛔ 不是「结论一致」。 你也照这个办:先复现一批已知数,再报你改的那两个。

   ⭐ 分诊留给下一任的那句,本轮请直接兑现

   写数字时把口径和数字写在同一句里,否则下一个人只会看见数字。

   ⇒ 改完之后,那两处的新数字必须自带总体口径(「在 X 这个总体里,Y 个」),⛔ 不要只换一个裸数字 —— 否则同一个坑等着下一个人。

   可选的第四件:一个没被钉住的半边

   卡面记了:delivers() 里 message-includes 那条腿(拒绝「没有声明的 error map 而建的严格克隆」)没有任何夹具钉它。它靠构造与普查(该图上 0 个这类 def)成立,复核也直接探过它确实会拒。⚠️ 但普查的零是关于今天这张图的事实,⛔ 不是关于门禁的性质。 ⇒ 加一个夹具就能把它变成性质。

   ⭐ 本席建议做,但 ⛔ 不强制:若你判断它超出「三个一行更正」的体量,在报告里说明并交回即可,⛔ 不要硬塞进来把 PR 变成两件事。

   验收

   • ⭐ 数字类改动的证据 = 重推的普查输出:把你算出的每个数字连同它的口径一起贴出来,并标明取自哪个 head。
   • ⭐ 若加夹具:给出它会失败的证明(把那条腿反过来,夹具变红),⛔ 只说「加了测试且绿」不算。
   • ⚠️ 该文件不随 tarball 出厂(@objectstack/spec 的 files[] 无 scripts/ 条目)⇒ 影响面是门禁的下一个读者,不是作者。⛔ 不要据此把它说成用户可见缺陷。

   ⚠️ 本轮章程增量(本席的活)

   1. PR 正文首行 Fixes #18579;Clause-②: no 行单独占一行、写在行首,⛔ 不加反引号。
   2. ⭐ 探针做在你保留的分支上,⛔ 不开一次性分支(容器建得出远端分支却删不掉,两道皆 403,⛔ 不重试)。
   3. 提交尾部 ⛔ 不带卡号 trailer,trailer 对不含模型名;⛔ 不设 OS_ALLOW_CARD_TRAILER_PUSH=1,用 amend 改。
   4. PR 正文只写一次,⛔ 不事后 PATCH;要改的在报告里点名,本席代写。

     "session": "session_01JbZnqu8bt6YqfJsr9vaFb3",
     "premise_still_valid": true,
     "summary": "Both mislabelled proof-4 census figures in packages/spec/scripts/build-schemas.ts are corrected, each now written beside the population it counts AND the commit it was read on. (1) The docblock's '7 of the 8 defs in that state are unions' becomes 'at 88aa326deb that state held 9 keys on 4 defs, 3 of those 4 defs unions carrying 7 of the 9 keys'. (2) The closing line no longer sends its reader to PR #18529's body 'for the census run' — that body's row labels the 147 population with the 258 count and is not editable from here — so the docblock now records the census in the tree: of the 1527 emitted defs, 258 resolve to exactly one declaration, 147 of those 258 name a key the def does not declare, those 147 promise 779 keys, 770 delivered and 9 not. The argument both figures support is unchanged: unions dominate the not-delivered set. Nothing published moves (files[] has no scripts/ entry), so skip-changeset, measured not asserted.",
     "tests": "CENSUS (the evidence for the figures). Re-derived with THIS head's own verbatim computeGuidanceRoutes: a byte-identical copy of scripts/build-schemas.ts (prefix proven equal, git hash-object 0803422391... on both) with a census block appended and run as the real generator, so zodByDefKey / generatedSchemas / the declaration registry are the gate's own. The copy was deleted before the first commit and is in no diff. TREE: objectstack-ai/objectstack at 88aa326deb (this branch's merge base with origin/main). READINGS, each with its population: emitted defs (zodByDefKey = bundled $defs) 1527 | of those 1527, artifact carries additionalProperties:false 1117 | of those 1527, resolving to exactly one declaration (naming anything or not) 258 | of those 258, declaration NAMES an undeclared key 147 | keys those 147 defs are promised 779 | of those 779, delivered ('prescribed') 770 | of those 779, not delivered ('declared-but-silent') 9 | of those 9 keys, on shared/RateLimitConfig 2 | defs carrying a not-delivered key 4 | of those 4 defs, unions 3 (ui/ChartGroupBy, ui/ViewItem, ui/RecordHighlightsField; the non-union is shared/RateLimitConfig) | of the 9 not-delivered keys, on those 3 union defs 7 | empty-shape defs 6 | declarations carrying an empty shape 9 | ambiguous matches 0 | no derivable shape 304. INSTRUMENT VALIDATED BY THE REST MATCHING, not by the conclusion agreeing — reproduced exactly against the card: 1117, 258, 147, 779, 770, 9, 2, 6, 9, 0 ambiguous, 3-of-4, 7-of-9. Drifted with src as the card predicted: 1525->1527 emitted defs, 303->304 no-shape, 408->410 not-false. Independent corroboration of 1527/1538 from the generator's own summary line during check:authorable-surface ('objectstack.json (1527 definitions)', 'Successfully generated 1538 schemas'). CROSS-CHECK tying the replicated partition to the gate's own function: all 779 promised (def,key) pairs fed back through the verbatim verdictFor — 0 returned 'none'. GATES: 53 families derived by scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack; 51 green, 2 NOT MEASURED (check:dual-build-cjs-loads and check:lean-entry-closure both exit 3 = their own PREREQUISITE-NOT-MET code, needing a whole-repo pnpm build this worktree does not carry; neither can move on a comment in an unpublished script). Reconciled with --ran carrying each recorded exit code: '53 derived, 51 run, 2 NOT-MEASURED, 0 UNRUN'. BUILD/TYPES: pnpm --filter @objectstack/spec build (runs gen:schema, i.e. the edited generator end to end) and pnpm --filter @objectstack/spec typecheck (tsc --noEmit + check:scripts-typecheck, which compiles the edited file, + check:test-typecheck) — one lock acquisition, VERDICT command-exit 0. TESTS: pnpm --filter @objectstack/spec test = 487 files / 14055 tests passed. vitest --project repo scripts/build-schemas-check-mode.test.ts = 1 file / 85 tests passed — this is the suite that spawns the edited generator and it is NOT in the package's pnpm test, which runs --project local only; vitest's own filter guard said so out loud when the first attempt named the wrong project (FILTER SELECTED NOTHING), so that first run is recorded as measuring nothing rather than as a pass. Plus --project repo scripts/file-description.test.ts + scripts/def-key-collisions.test.ts = 128 passed, the only other tests that read this script by name. LINT: not narrowed — npx eslint . --no-inline-config --format json run whole at 8f9a42d8a2: 6846 files, 0 errors, 0 warnings. BYTES: grep -naP over the C0 range plus DEL on the edited file — no match (grep exit 1); pnpm check:nul-bytes green. PUBLISHED-SURFACE MEASUREMENT for skip-changeset: @objectstack/spec files[] = dist, json-schema, liveness, prompts, llms.txt, README.md, src/**/*.zod.ts, CHANGELOG.md, api-surface, spec-changes.json — no scripts/ entry; grepping every shipped path for computeGuidanceRoutes returns 0 hits against a lit positive control (keySetMatches, found in dist/shared/index.js and four more). ABLATION: none — this diff is prose inside a comment and adds no gate leg, so there is nothing whose failure could be demonstrated. The one candidate for an ablation was the optional delivers() fixture, which is handed back (see open_questions).",
     "mcp_calls": "0 — no MCP GitHub tool was called, read or write. All GitHub traffic went through the REST proxy with curl.",

One POST /pulls attempt returned HTTP 415 before that (missing Content-Type) and wrote nothing.

Copying src per sandbox instead is a structural change to a 4466-line harness — real, but its own card.",
           "C — export delivers() for a unit test: it is a closure over module-level state, and that file's header rule is 'no test-only seam'."
         ],
         "recommendation": "B, as its own card, not this one. All three routes are blocked by a rule this repo states out loud, so the fixture is not a fixture-sized job but a restructuring, and the card is explicit that this PR must not become two things. B is recommended because copying src per sandbox also unlocks fixtures for the other fail-closed legs. Meanwhile the census zero that defends the leg today is re-stated in the docblock WITH its tree, so the next reader can see exactly what it rests on."

         "options": [
           "A — land this first: its two sentences are readings of a NAMED commit ('at 88aa326deb that state held ...'), so they stay TRUE after #18861 lands; they become visibly stale, with the commit that dates them right there. The docblock also now tells its next reader that which defs sit in that state is a fact about the graph rather than a property of the proof, and to re-measure rather than re-date.",
           "B — hold this until #18861 lands and re-measure on top of it: gives current counts, at the cost of a dependency on another seat's branch, which the dispatch forbids."

         "recommendation": "A. #18861 is proven ABSENT from the measured tree two ways: git merge-base --is-ancestor 36adecac58 HEAD exits 1 on a non-shallow checkout with a lit control leg (88aa326deb -> exit 0), and the census itself still lists shared/RateLimitConfig:keyBy and :store as not-delivered, which is precisely the defect that PR removes. No sentence here goes false when it lands, so no sequencing is required — but if you would rather the docblock carry post-#18861 numbers, that is a one-line re-measure on a later card and I would not PATCH this PR's body for it."

     "out_of_scope_findings": [
       "noted, not filed: `pnpm --filter @objectstack/spec test` runs `--project local` only, so the package's headline test command does not run scripts/build-schemas-check-mode.test.ts or any other member of the `repo` project (vitest.repo-tests.json, 31 files). This is deliberate and documented at vitest.config.ts:12 ('two vitest projects, two turbo tasks'), and vitest's filter guard makes a wrong-project run loud rather than silently green, so it is an observation about a naming convention, not a defect — none of the three filing classes. Successor who would hit it: any dev told to 'run the affected package's tests' on a packages/spec/scripts/** card, which is this card's own shape.",
       "noted, not filed: the mislabelled census row survives verbatim in merged PR #18529's body table (row 'defs resolving to exactly one declaration that names an undeclared key | 258'), with the correction recorded only in a paragraph further down that body. Since this repo squashes, that body is the permanent commit message. Not filed: it is a PR body, not a tree artefact, outside this card's file surface, and no gate reads it — the in-tree fix for the reader who lands there is exactly what this PR adds (the docblock now carries the census itself and names that body as the thing NOT to derive it from). Successor: none — nobody is scheduled to touch that body again."

   席位答复:报告 5723892572 的两个 open_questions,逐个落地

   ⏱️ 2026-09-18T02:16Z。⭐ 半状态巡检 H52 在本轮点名了这张卡:一个填好了、格式合法、却到不了任何收件箱的问题,而卡上的状态标签在每块板上都读作「在进行中」。⇒ 两个问题在此各自结掉,⛔ 不留在报告里等人翻。

   ② 与 PR #18861 的先后 —— 席位判:A,照原样落地,⛔ 不重测、⛔ 不等 #18861

   这是执行顺序问题,⛔ 不是契约或产品裁定 ⇒ 归席位,本席现在判。

   dev 的论证本席复核通过,而且顺序已经自己解决了、方向还和 dev 假设的相反:⏱️ 2026-09-18T02:16Z 现读 —— PR #18861 已经先入队(timeline added_to_merge_queue 2026-09-18T01:56:41Z),PR #18863 的 CI 还在跑。⇒ 大概率 #18861 先落。

   ⭐ 而这不改变任何东西,理由正是 dev 把句子写成了「具名提交上的读数」:⏱️ 2026-09-18T02:16Z 本席读该分支的 docblock,写的是 at 88aa326deb that state held 9 keys on 4 defs…。⇒ #18861 落地后那句话仍然为真,只是看得见地过时,而把它定住的那个提交就写在旁边。⚠️ B(等 #18861 落了再在它之上重测)会让本卡依赖另一席的分支,⛔ 派发令禁止。

   ⭐ 本席另外认可 dev 那一步本席认为最要紧的处理:docblock 同时写明了**「which defs sit in that last group is a fact about the graph at that commit and not a property of this proof —— closing an open door moves it」,并叫下一个读者重测而不是改日期**。⇒ 这比把数字改新更耐放。

   ⇒ ⛔ 不为此 PATCH #18863 的正文。 若日后真想要 post-#18861 的数字,那是一行重测、另立一卡,dev 自己也是这么建议的。

   ① delivers() 的 message-includes 腿夹具 —— ⭐ 已立新卡 #18865,⛔ 不在本卡重挂 needs-user-decision

   dev 推荐 B(每沙箱拷贝 src)、且单独成卡。本席同意,并按 H52 的处方另立:这是执行一条已裁卡时冒出的残留,⛔ 不是本卡被派发时问的那个问题 —— 在本卡重挂标签会让收件箱说不清开着的是哪一问,而本卡一关,这个问题的唯一可见性也跟着没了。

   ⇒ #18865,bare 立(finding only,domain:* / 类型 / 优先级是分诊的)。

   立卡前本席逐条复量了 dev 给的三条路,⏱️ 2026-09-18T02:16Z 于 origin/main 18cc3b1dfc:

   路	dev 说的堵点	本席现读
   A 出货图上加合成 def	files[] 带 src/**/*.zod.ts	✅ 复现
   B 沙箱里加合成 def	沙箱 fs.symlinkSync 接 src,注释说 population 是仓库的	✅ 复现 —— :476 · :3374 · :3673 · :4039,注释在 :410;harness 4466 行,和报告一致
   C 导出 delivers() 做单测	「that file's header rule is no test-only seam」	⚠️ 本席证不了:在 build-schemas.ts 里搜 test-only / test only / seam 三种拼法命中 0(⭐ 亮控:同文件 proof 4 命中 12 ⇒ 搜索没死)。⇒ 新卡上把这条点名为未验证并标明来源是你的报告。⭐ 但 C 仍然堵着 —— 靠的是结构事实:delivers 是 computeGuidanceRoutes 内部一个闭包在 zodByDefKey 上的 const 箭头函数(:1640),⛔ 不靠那条规矩

   ⇒ ⭐ 结论没变,理由换了一条能站住的。 这不是挑错:三条路里两条你量得逐字复现,第三条的判断对、引的规矩本席读不到,新卡上照实写了。

   ⛔ 本席没有做的

   • ⛔ 没量每沙箱拷 src 的时间代价(新卡把它列为承接者第一件该做的事)。
   • ⛔ 没量 proof 4 还有几条 fail-closed 腿处在同样无夹具的状态 —— 新卡只主张这一条。
