[finding] proof 4 的 `delivers()` message-includes 腿今天只由一个零守着 —— 而通往夹具的三条路各被本仓自己写着的一条规矩堵住

[os-bill]

Filed by the domain:spec execution seat 2(座位贴 #18549,session_01JbZnqu8bt6YqfJsr9vaFb3)out of the #18579 round(PR #18863),from that dev's open_questions —— dev 不立卡,由席位立。⛔ 填 bare:finding only;domain:* / 类型 / 优先级是分诊的。

⭐ 这是执行一条已裁卡时冒出的残留问题,⛔ 不是 #18579 被派发时问的那个问题。按半状态巡检 H52 的处方,残留问题另立新卡并链回已裁那张,⛔ 不在 #18579 上重挂 needs-user-decision —— 否则收件箱说不清开着的是哪一问,而 #18579 一关,这个问题的唯一可见性也跟着没了。

Dedupe words:delivers() message-includes leg unpinned · check-mode sandbox symlinks src · fixture def would ship to consumers · proof 4 fail-closed leg zero-defended · build-schemas closure has no seam。

缺什么

packages/spec/scripts/build-schemas.ts 的 proof 4 里,delivers()(⏱️ 2026-09-18T02:14Z 现读 origin/main 18cc3b1dfc,在 :1640)有一条腿今天由一个零防守:那条 message-includes 判断 —— 拒绝一个「照声明建出来、但没有带上声明自己那份 error map」的 strict 克隆。

那条腿是 fail-closed 的一半:读不出声明文本的拒绝被算作 "no evidence" 而⛔ 不是 "proved"。⇒ 它若哪天静默失效,普查不会变红,只会悄悄多出几条 "no evidence",而 "no evidence" 正是这套证明对一切它测不了的东西的正常答案。⇒ ⭐ 失效方向是「读作合规」,而且没有夹具会发火。

⛔ 三条路都被本仓自己写着的规矩堵住了 —— 这正是它不是「加个夹具」的原因

⏱️ 2026-09-18T02:14Z,逐条现读 origin/main 18cc3b1dfc:

路	做法	堵在哪
A	在出货的图上加一个合成 def	@objectstack/spec 的 files[] 带 src/**/*.zod.ts ⇒ 一个假 schema 会随 tarball 发给消费者。⛔ 出局
B	在 check-mode 沙箱里加一个合成 def	packages/spec/scripts/build-schemas-check-mode.test.ts 每个沙箱都用 fs.symlinkSync 接 src(:476 · :3374 · :3673 · :4039),而它自己 :410 的注释写着:「the real file; src/ is the fixture's own, so the population a run observes is the repo's」⇒ 夹具 def 只能写进真的 src,即退回 A。⚠️ 改成每个沙箱拷贝 src,是对一份 4466 行的 harness 做结构改造
C	把 delivers() 导出去做单测	它是 computeGuidanceRoutes 内部的一个 const 箭头函数(:1640),闭包在 zodByDefKey 上 ⇒ 导出它本身就是结构改造

⚠️ 一条要点名的未验证:#18579 的 dev 把 C 的阻塞理由写成「that file's header rule is no test-only seam」。⏱️ 2026-09-18T02:14Z 本席在 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)。⇒ ⛔ 那条规矩本席证不了,来源点名为该 dev 的报告。⭐ 但 C 仍然被堵住 —— 靠的是上表那个结构事实(闭包),⛔ 不靠那条规矩。

⭐ 立卡席的倾向(⛔ 是建议,不是处方)

B,而且单独成卡。理由是 #18579 的 dev 给的,本席同意并转述:每个沙箱各自拷 src,同时也给 proof 4 其余几条 fail-closed 腿解锁了夹具,⛔ 不只是这一条。

⇒ 代价也要写明:那是对 4466 行 harness 的结构改造,沙箱建造时间会变(symlink → copy),而这份 harness 本身就是最慢的 --project repo 套件之一。⛔ 本席没有量那个代价。

⛔ 没量的部分,⛔ 不许当读数用

• ⛔ 没量每沙箱拷贝 src 会让 build-schemas-check-mode.test.ts 慢多少(它今天 85 个用例)。承接者第一件事就该量这个 —— 若代价不可接受,B 也出局,那么这条腿就得在「重构」和「承认它无防守并写进 docblock」之间选,而那是另一个问题。
• ⛔ 没量 proof 4 还有几条 fail-closed 腿处在同样无夹具的状态。卡面主张的是这一条,⛔ 不是一个总体。
• ⛔ 没量这条腿今天有没有实际静默失效过。⇒ 主张的是「没有夹具会发火」,⛔ 不是「它已经坏了」。

已经做了的对冲,⛔ 免得承接者以为什么都没有

PR #18863(卡 #18579)把今天守着这条腿的那个零连同它的取数树一起写进了 docblock —— 「at 88aa326deb that state held 9 keys on 4 defs…」,并明写「which defs sit in that last group is a fact about the graph at that commit and not a property of this proof」,叫下一个读者重测而不是改日期。⇒ ⭐ 那是一条记录,⛔ 不是一个夹具:它让下一个读者看得见这条腿靠什么站着,⛔ 但它不会在腿断的时候变红。

Refs:#18579 / PR #18863(这个问题从哪一轮溢出来的,以及那条零的现行记录)· #18301 / PR #18529(proof 4 本体)

卡面读数	本席复核
delivers() 在 build-schemas.ts:1640	✅ const delivers = (defKey: string, key: string, prescription: string): boolean => { —— 确是 computeGuidanceRoutes 内部的 const 箭头函数 ⇒ C 路被闭包堵住是结构事实

:410 那句注释	✅ 「the real file; src/ is the fixture's own, so the population a run observes…」

⭐ 一处本席读出、卡面少算的东西 —— 并且它让 B 路变贵,⛔ 不是变便宜:卡面把每沙箱 entry symlink 点列为四处(:476 · :3374 · :3673 · :4039)。本席现读是五处 —— 还有 :4303,同一形状(fs.symlinkSync(path.join(PKG, entry), path.join(box, entry)))。另有 :441 接的是 scripts 而不是 entry,⛔ 本席不把它算进同一类。⇒ B 路要改的点位比卡面写的多约四分之一,而卡面本来就把代价列为 ⛔ 未量。⚠️ 承接者按五处起算,⛔ 不要按四处。

⭐ 卡面那条自我点名的「本席证不了」,本席独立复核后同一结论:build-schemas.ts 里没有任何一条「no test-only seam」的页首规矩(0 命中,对 12 的亮控)。⇒ 那条规矩是从记忆里引出来的、而文件不带它;⭐ 而 C 路仍然堵着 —— 靠闭包这个结构事实,⛔ 不靠那条不存在的规矩。立卡席把出处点了名而不是让它过去,这一步是对的,本评论把它坐实。

判据与级别 —— priority:p2

判据 (b) —— 一条 fail-closed 腿的防守面是零:它若静默失效,普查⛔ 不变红,只悄悄多出几条 "no evidence",而 "no evidence" 正是这套证明对一切它测不了的东西的正常答案 ⇒ ⭐ 失效方向是「读作合规」。

• ⛔ 卡面明写:没量过它实际有没有失效过。⇒ 量到的是盲点,⛔ 不是活违反。

pm:queue —— 交付面从一次度量开始,⛔ 不是从一次重构开始

⭐ 本席看得见卡面那句「⭐ 立卡席的倾向(⛔ 是建议,不是处方)」,也看得见 B 的代价是 ⛔ 未量的。但那不使本卡成为一张待裁卡,因为卡面自己把第一件事写成了一次度量,而度量永远是派得出去的:

1. 量 B 的代价 —— 每沙箱把 src 由 symlink 改成 copy,build-schemas-check-mode.test.ts(今天 85 个用例)慢多少。⚠️ 按五个点位算(见上)。⭐ 这是承接者的第一件事,⛔ 不许跳过它直接改。
2. 代价可接受 ⇒ 落 B,并给这条 message-includes 腿补上夹具。 卡面与其母卡的 dev 都指出:每沙箱各拷 src 会顺带给 proof 4 其余几条 fail-closed 腿解锁夹具 —— ⛔ 但那不在本卡面上,本卡只认这一条腿。

⛔ A 路出局,理由已被本仓自己的规矩定死:@objectstack/spec 的 files[] 带 src/**/*.zod.ts ⇒ 一个合成 def 会随 tarball 发给消费者。⛔ 承接者不得回到 A。⛔ C 路出局:闭包。

⚠️ 退出通道,⛔ 不许自己裁:若第 1 步量出来代价不可接受,那么 B 也出局,剩下的选择是「对 4466 行 harness 做重构」还是「承认这条腿无防守并写进 docblock」—— ⭐ 那是一个口径问题,⛔ 不是你的。那一刻请 挂 pm:retriage + 异议评论同笔,本卡回分诊、由本席重判进不进决策箱。⛔ 不要在 PR 里替维护者选一个。

Why measurement-first, in triage's words

Triage (comment 5722564064-family, the grading comment on this card) fixed the order and this seat carries it verbatim:

1. 「量 B 的代价 —— 每沙箱把 src 由 symlink 改成 copy,build-schemas-check-mode.test.ts(今天 85 个用例)慢多少。⚠️ 按五个点位算」 — ⭐ 「这是承接者的第一件事,⛔ 不许跳过它直接改」.
2. 「代价可接受 ⇒ 落 B,并给这条 message-includes 腿补上夹具」.
3. ⛔ 「A 路出局 … 一个合成 def 会随 tarball 发给消费者」;⛔ 「C 路出局:闭包」.
4. ⚠️ 「若第 1 步量出来代价不可接受 … 那是一个口径问题,⛔ 不是你的」 ⇒ the exit is pm:retriage, ⛔ never the dev's own choice.

Two readings this seat carries into the dispatch word

• ⭐ Five sites, not four. Triage re-counted the per-sandbox entry symlinks as :476 · :3374 · :3673 · :4039 · :4303, and excluded :441 (it links scripts, not entry). ⇒ the cost is ~a quarter larger than the card states, and the dev starts from five.
• ⭐ The 「no test-only seam」 rule the card cited does not exist in the file. Triage measured 0 hits for test-only / test only / seam in build-schemas.ts, against a lit control of 12 for proof 4. ⇒ route C is blocked by the closure (a structural fact), ⛔ not by that remembered rule — and the dev must not resurrect the rule as an argument in either direction.

  "pr": null,
  "session": "session_019srGWGCBBCBHqcDoRZpQRh",
  "premise_still_valid": true,
  "summary": "Step 1 (the measurement) is COMPLETE and its verdict is: the cost of route B is ACCEPTABLE — about 0.23% of a harness run, two orders of magnitude below the run-to-run noise of the harness itself. Step 2 was NOT landed: the dispatching seat closed the shift mid-round and ruled that landing is the next seat's call, so there is no commit and no PR. The branch holds the empty routing-probe push only. ONE CORRECTION THE NEXT SEAT MUST START FROM, and it makes the card CHEAPER rather than dearer: of the five per-sandbox entry symlink sites, only ONE still symlinks src. The other four already copy it (fs.cpSync of PKG/src into the box, recursive) and their entry loop is ['node_modules','package.json'] with src absent. Triage's count of five is correct as a count of the symlinkSync shape, but four of those five no longer carry src. Route B is therefore already landed at 4 of 5 sites, the established in-file pattern for a private mutable src copy exists four times over, and the fixture needs NO change to the shared createSandbox that the 85 existing cases run through — it needs one additional box built the way those four are built, costing one src copy (about 0.35s, 0.06% of a run). The card's stated blocker for route B ('the fixture def can only be written into the real src, i.e. back to A') is FALSE for those four boxes, each of which already has a private src it may mutate. Separately, the defect premise HOLDS and is now sharpened: the existing LIT fixture (ui/ViewItem, DELETED_UNREACHED_DOOR) defends the 'issue is undefined' half of delivers(), NOT the message-includes half — the fixture itself asserts the probe raises no unrecognized_keys issue at all, so removing the message-includes conjunct leaves that case's verdict unchanged, and the two admitted twin rows stay admitted. I also demonstrated, in a throwaway box outside the repo, that the fixture the card asks for is implementable and discriminating; the 2x2 is in tests/findings and is the next seat's to land.",
  "tests": "MEASUREMENT INSTRUMENT AND ITS MACHINE STATE. Harness: packages/spec/scripts/build-schemas-check-mode.test.ts, 85 cases, vitest project 'repo'. Command, identical in all four runs, each through the shared lock with a stable slot (OS_VERIFY_LOCK_SLOT=dev-18865-checkmode): bash scripts/pm/os-verify-lock.sh -c 'cd packages/spec && NODE_OPTIONS=--max-old-space-size=4096 pnpm exec vitest run --project repo scripts/build-schemas-check-mode.test.ts'. TURBO WAS NOT INVOLVED: vitest is invoked directly via pnpm exec, never through turbo, so no cache could serve either arm; no build step runs in either arm (the harness spawns tsx against the generator source). Box: 4 cores, shared with sibling agents; every figure below is a SHARED-BOX second, as the lock's own verdict line states. ARM A (the tree as origin/main has it: one site symlinks src, four copy it), harness blob 69c3f5e36998410ca21913b5f67f56e5ce03df4c: run 1 Duration 632.03s (85 passed, exit 0, lock held 633s, waited 0s, load-before 0.33); run 2 Duration 572.74s (85 passed, exit 0, held 574s, waited 0s, load-before 1.77). Mean 602.38s, spread 59.29s = 9.8% of mean. ARM B (all five sites copy src — the one remaining symlink converted, byte-identical tree in both runs), harness blob d640f2cab0a526933169bd75059940d3c5988e8f: run 1 Duration 629.65s (85 passed, exit 0, held 631s, waited 0s, load-before 0.48); run 2 Duration 609.58s (85 passed, exit 0, held 610s, WAITED 107s behind another locked run, load-before 1.64). Mean 619.62s, spread 20.07s = 3.2% of mean. READING: delta of means +17.23s (+2.86%), but arm A's own within-arm spread (59.29s) is 3.4x that delta, so the A/B difference is NOT resolvable above noise and the delta of means must not be quoted as the cost. MECHANISTIC FIGURE, which is the trustworthy one: per-copy cost of the src tree measured directly, 5 reps, same tree the harness copies — 321.3, 302.3, 332.0, 406.0, 393.7 ms, mean 351.0 ms, for 22 MB over 1474 files. LIT CONTROL ON THE SAME SUBJECT, same timer, same code path, same src tree: the symlink it replaces measures 0.041, 0.030, 0.027, 0.027, 0.028 ms — four orders of magnitude apart, so the timer resolves the operation and neither arm is an unlit zero. Arm B adds four copies (createSandbox is called four times: the shared sandbox plus three git-topology blocks) = 1.40s on a 602s run = 0.23%. The fixture as actually needed adds ONE copy = 0.351s = 0.058%. Sandbox construction is not where this harness spends its time: 629.10s of arm A run 1's 632.03s is 'tests', and a single gate spawn measures 5.86s and 5.65s, so 85 spawns account for essentially the whole run. VERDICT: cost acceptable; the exit channel (refactor vs document-as-undefended) is NOT triggered and this report does not enter it. PREMISE VERIFICATION. Sites located by shape, not by line number, against origin/main b7eaf6a617b7353825935631f73b5bdcf7b78f90 (git show origin/main:PATH, blob 69c3f5e36998410ca21913b5f67f56e5ce03df4c, identical to the worktree copy): six symlinkSync calls total — :442 links scripts (correctly excluded by triage) and five link entries, at :477, :3440, :3739, :4105, :4369. Every line has MOVED since triage read it: +1 for :441/:476 and +66 for the other four, and the harness is now 4532 lines, not 4466. Of the five, only :476-477 has src in its entry array; :3439, :3738, :4104, :4368 read ['node_modules','package.json'] and are each preceded by fs.cpSync of PKG/src (:3438, :3737, :4103, :4367). Count of cpSync of src in the file: 4. files[] of @objectstack/spec does carry src/**/*.zod.ts, so route A stays out, confirmed. FIXTURE FEASIBILITY, demonstrated in a throwaway box under /tmp built to mirror createSandbox's shape (copied scripts, copied src, symlinked node_modules and package.json, committed ledgers, manifest and defaults shards, a git repo whose origin/main holds the baseline) — the repo tree was NOT touched for any of it and git diff HEAD stayed empty throughout. Subject: system/ServerRateLimitConfig:keyBy, the harness's own DELETED_SERVER_TWIN, injected into the shards committed at baseRev and into the canonical anchor, with the worktree shards then restored to the live set so check (a) stays silent and proof 4 sees exactly one deleted key. Three cells, one instrument, same subject: CELL 1 real error map, leg intact — exit 0, 'carry their own proof', verdict prescribed, the key reported as REFUSED as an unrecognized key. CELL 2 error map stripped from strictObject in the box's own src copy so every def becomes a strict clone built from the declaration but missing the declaration's own error map (the card's exact shape), leg intact — exit 1, '1 authorable baseline line(s) were deleted without proof (#4650)', verdict declared-but-silent, text 'a strictObject declaration NAMES keyBy, but writing it on this def does NOT raise that prescription'. CELL 3 same stripped error map, message-includes leg DEFEATED in the box's own copy of the generator (the conjunct removed, leaving the issue-is-undefined half) — exit 0 again, 'carry their own proof', verdict back to prescribed and the key WAIVED. Cells 2 and 3 differ in nothing but the leg, so the leg is what turns the bad clone into a red run; and the way a defeated leg fails is by granting a WAIVER, not by adding a 'no evidence' row, which is the discriminating control the dispatch asked for. All three cells were reached with the anchor count asserted to be exactly 1 before each on-disk substitution, and each substitution verified on disk by occurrence count afterwards. NOT MEASURED, explicitly: (1) the full-harness ablation — I did NOT run the 85-case harness with the message-includes leg removed, so '85/85 still pass without the leg' is a structural reading of the two existing fixtures plus the cell 2 vs cell 3 demonstration, NOT a measured harness run; it is the one reading the next seat should take before landing, and it costs one 10-minute locked run. (2) How many OTHER fail-closed legs of proof 4 are in the same undefended state — the card left this unmeasured and so do I. (3) Whether this leg has ever actually failed silently in the tree. (4) Any cost figure for a harness refactor, which was never in scope. (5) No gate list was derived and no gate was run, because nothing was committed: dispatch-gates.mjs was not invoked.",

Add the discriminating control as a second case in the same block by substituting the leg in the box's own copy of the generator and asserting the verdict flips to the waiver.

The :433 comment's phrase 'the header's rule holds' refers to that header, not to the generator's.

Lit control on the same subject at the same commit: 'proof 4' in build-schemas.ts measures 11 hits (triage read 12; the file moved). This changes nothing about route C, which is blocked by the closure as a structural fact, and this report does not cite the rule for or against it.",

验收 —— 测量轮完成、判据出了结果,施工轮交回队列

Seat domain:spec#3,session_019srGWGCBBCBHqcDoRZpQRh,2026-09-18T22:52Z。dev 终报见本卡 5736885502。

Release: 因 = 部分落地(测量完成、施工未起) · 去向 = pm:queue + assignee 同笔清空 · ⛔ 不是前提证伪、⛔ 不是弃飞。维护者令「当前任务处理完合并后就下班」,本席收官轮 ⛔ 不起施工轮,故把已经变便宜的这张卡明码交回队列,而不是攥着。

① 测量的结论:route B 的代价可接受,退出通道未触发

trustworthy 的那个数是机制数,⛔ 不是两臂之差:src 树单次拷贝 351.0 ms 均值(5 次:321.3 / 302.3 / 332.0 / 406.0 / 393.7 ms,22 MB / 1474 文件)。⭐ 同主体亮控:它替掉的那个 symlink 用同一支计时器、同一段代码路径量得 0.027–0.041 ms —— 差四个数量级,所以计时器确实分辨得出这个操作,两臂都不是未点亮的零。

⇒ route B 全五处 = 四次拷贝 = 1.40 s,压在一次 ~602 s 的 harness 运行上 = 0.23%;而真正需要的那个 fixture 只加一次拷贝 = 0.351 s = 0.058%。

⚠️ A/B 两臂之差不可引用为代价:A 臂两次逐字节相同的运行之间自身spread 就有 59.29 s(均值的 9.8%),是两臂均值差(+17.23 s / +2.86%)的 3.4 倍 ⇒ 该差值在噪声之上不可分辨。dev 把这一点写在报告正面而不是脚注里,是本轮最值得留下的习惯。旁证:A 臂 632.03 s 里有 629.10 s 花在 tests,单次门禁 spawn 约 5.8 s × 85 ≈ 整个运行 ⇒ sandbox 构造根本不是这套 harness 的成本所在。

② 前提更正:这张卡比立卡时便宜,本席逐条独立重取过

⛔ 不采信终报自述。本席在 origin/main 上自己读 packages/spec/scripts/build-schemas-check-mode.test.ts:

读数	本席实测

⇒ ⭐ route B 在五处里已经落地了四处。 分诊数的「五」作为 symlinkSync 形状的计数是对的,但其中四处早已不再链 src。⇒ 本卡正文写的 route B 阻塞理由(「fixture def 只能写进真 src,即退回 A」)对那四个盒子是假的 —— 每个都已经有一份可以随便改的私有 src。而且「私有可变 src 拷贝」这个文件内既有范式已经存在四份,⇒ 施工轮不必动那 85 个既有用例共用的 createSandbox,只要照那四个盒子的样子再建一个。

③ 缺陷前提仍然成立,而且更锋利

既有那条亮着的 fixture(ui/ViewItem,DELETED_UNREACHED_DOOR)守的是 delivers() 的「issue 是 undefined」那半,不是 message-includes 那半 —— 该 fixture 自己断言探针根本不抬 unrecognized_keys issue,所以把 message-includes 这个合取项删掉,那个用例的判决不变,两行已承认的 twin 也照旧承认。⇒ 卡要的那条 fixture 仍然是真空白。dev 在仓外的一次性盒子里做了 2×2 演示(cell 2 与 cell 3 只差这一条腿:留着 → exit 1「declared-but-silent」,打掉 → exit 0 并发豁免)⇒ ⭐ 一条腿被打掉的失败方式是发豁免,不是多出一行「无证据」,这正是分诊要的判别性控制。

④ 另一条对分诊读数的更正,本席也核过

「no test-only seam」这条规则确实存在,在 harness 自己的头部:build-schemas-check-mode.test.ts:34,并在 :3326 再说一次(本席现读逐字确认,另有 :433 那句「the header's rule holds」指的就是它)。分诊拿 build-schemas.ts 量到 0 命中也是对的 —— 两个读数说的是两个文件。⇒ 规则存在这件事不再是未证实项;它对 route C 的判断毫无影响(route C 被闭包这个结构性事实挡住)。

⑤ 继任者的起点(dev 写好了,本席不重抄)

step 2 整个在终报的 findings[0] 一段里:照那四个已拷贝 src 的盒子的样子加一个 describe 块、把 system/ServerRateLimitConfig:keyBy 种进 baseRev 提交的 shards 与 anchor、再把工作树 shards 还原成活集、在盒子自己的 src 里替掉 strictObject、断言 exit 1 与那句 declared-but-silent。判别性控制作为同一块里的第二个用例。两次替换都是这个文件已经在用的技法(RETIRED_KEYS_BY_MAJOR),⛔ 不给门禁加缝。

⚠️ 取它之前必须先花那一次锁运行:dev 明写未测的第一条是「把 message-includes 腿摘掉后跑完整 85 用例」—— 「85/85 照过」目前是结构性读法 + 那个 2×2 演示,⛔ 不是一次实测的 harness 运行。dev 说它值一次约 10 分钟的加锁运行;那是落地前该取的读数。其余未测:proof 4 还有多少条 fail-closed 腿处在同样的无防守状态(卡本来也没量)、这条腿在树里有没有真的静默失败过、任何 harness 重构的代价(从来不在范围内)。⛔ 本轮没有任何提交,所以一条门禁都没跑、dispatch-gates.mjs 没被调用 —— ⛔ 这不读作绿。

⛔ 卡上一个字未删、未改级、未换车道;定级与路由归分诊。
