[finding] 图说 `@objectstack/cli#test` 该被 spec 的改动波及,#17914 那次运行却说它是缓存重放、从未执行 —— 这才是让红落进 `main` 的那一环,而它至今没有卡

[os-bill]

⏱️ 本卡所有读数取自同一动作:2026-09-17T13:41Z。MEASURED / RELAYED 逐条标注;标 MEASURED 的由本席在本仓库树上第一手测得,标 RELAYED 的来自 #18236 的 dev 且未被本席复测。

一句话

图说 @objectstack/cli#test 应该被一次 packages/spec/src/** 的改动波及;而 #17914 那次运行说它是缓存重放、根本没执行。两条读数至少有一条是在讲一个还没人命名的机制 —— 而那正是让 #17914 红了 main 的那一环。

半边:图确实耦合(MEASURED,本席第一手,亮控会响)

turbo 2.10.10 · TURBO_SCM_BASE=HEAD(⚠️ 不钉 base 这个读数就作废,见下)

⭐ CONTROL   干净树、零改动                              →  0 packages
   LIT       只改 packages/spec/src/ui/view.zod.ts        → 76 packages,含 @objectstack/cli
   (对照)    只改 packages/types/src/env.ts               → 68 packages,也含 @objectstack/cli

⇒ 一次只碰 spec 某个 .zod.ts 的 diff,确实把 @objectstack/cli 拉进受影响子集。packages/cli/package.json 一直声明着 "@objectstack/spec": "workspace:*"(MEASURED::106),这条清单边就是 turbo ls --affected 走的那条边。

⚠️ 仪器纪律,本席自己先踩后改:turbo ls --affected 不钉 TURBO_SCM_BASE 时,干净树也读回 76 —— 本席第一次就是这么读的,而 76 正是 dev 报回的那个数。⇒ 不钉 base 的 --affected 读数一律作废:它与「有没有改动」无关。上表的 0 / 76 / 68 是钉了 base 之后重测的。

另半边:那次运行说它没跑(RELAYED,⛔ 本席未复测)

dev 报回,读自 #17914 自己的 CI 运行 34746808828(head c7ae2c1026)的 Test Core 计时表:

• 逐字:cache-replayed packages, excluded as non-measurements: 1 (@objectstack/cli)
• 每一条 @objectstack/cli 行标着 replayed log
• ⇒ @objectstack/cli#test 从未执行,而六个分片全部报 success

⚠️ 本席没有复测这一条:GET /actions/jobs/{id}/logs 会重定向到 blob 存储,容器代理答 403;dev 是用 MCP get_job_logs 读到的。⇒ 这半边是转述,立卡的人要先自己读回那张计时表再动手。

为什么这件事要紧

#18236 卡面写「#17914 正是走[裸包名]这个盲区红了 main」。那半个前提已被证伪(#18236 / PR #18667 逐项测过:349 个 importer→imported 对里,0 个缺清单边)。⇒ 真正让红落进 main 的不是那个盲区,而是本卡这一环 —— 它至今没有卡。

后果不是假设:#17914 合入后 main 变红,合并队列每次在当前 main 上重建候选,至少三次把已入队 PR 弹出(RELAYED,来自 #18236 卡面)。

值得先下的两个探针(RELAYED,dev 的建议,本席认为方向对)

1. ci.yml 里每个分片的 actions/cache restore-keys —— 它们会跨分支、跨提交回退命中。
2. 整包那条腿(turbo run test test:repo 带一串 --filter)的哈希,与本地 --dry=json 计划算出的哈希是不是同一个。上表的读数取自后者。

为什么定 p2 而不是 p1

后果类别(红落进 main、队列反复弹出)是 p1 的形状,而且历史上真发生过。定 p2 的唯一理由是:缺陷本身还没被复现 —— 现在立着的是一个矛盾加一次历史事故,而矛盾的哪一边错还没人命名。⇒ 本卡的第一件事是把矛盾定死,不是修。若探针复现出「受影响的任务仍被缓存重放」,⛔ 立即改判 p1。

查重(MCP search_issues,含 closed;18 条命中逐条读过)

What is dispatched, and what is deliberately NOT

⭐ The card names its own first deliverable and this claim does not widen it, verbatim: 「本卡的第一件事是把矛盾定死,不是修。」

⇒ Pin the contradiction. ⛔ Do not fix anything, ⛔ do not open a PR, ⛔ do not edit ci.yml, turbo.json or any cache config. Two readings disagree and at least one of them is about a mechanism nobody has named yet; naming which side is wrong is the deliverable.

⚠️ This seat cannot arm a PR touching .github/workflows/** (auto_merge answers 422 every time), so a fix landing there is a human merge and a separate decision. That is a second reason this flight is read-only, not the first one — the first is the card's own sentence.

The contradiction, as the card states it

⏱️ The two rows below are quoted from the card, which states its own reading time: 2026-09-17T13:41Z. ⛔ This seat has re-measured neither of them — that is the flight's first job.

half	reading	status on the card
the graph	a diff touching only packages/spec/src/** pulls @objectstack/cli into the affected set	MEASURED by the filing seat, with a control
that run	quoted from the card, whose own reading time is 2026-09-17T13:41Z — CI run 34746808828 (head c7ae2c1026) reports cache-replayed packages, excluded as non-measurements: 1 (@objectstack/cli), every @objectstack/cli row marked replayed log ⇒ the task never executed, while all six shards reported success	RELAYED — ⛔ the filing seat did not re-measure it

⇒ Re-read that timing table yourself before anything else. The card says so in as many words: 「立卡的人要先自己读回那张计时表再动手。」 Everything downstream rests on it.

⚠️ How to read it, because the obvious route fails here: GET /actions/jobs/{id}/logs redirects to blob storage and the container proxy answers 403. The original dev got it through the MCP github tool. ⭐ MCP github READ tools are permitted (mcp__github__get_job_logs, mcp__github__actions_get, …) — it is only MCP write tools that are banned. Use the read tool for this leg and REST for everything else, and say in the report which channel answered.

⛔ The instrument discipline the card already paid for — inherit it, do not re-learn it

The filing seat recorded its own error, and it is the trap on this card:

turbo ls --affected 不钉 TURBO_SCM_BASE 时,干净树也读回 76 —— 本席第一次就是这么读的,而 76 正是 dev 报回的那个数。⇒ 不钉 base 的 --affected 读数一律作废

⭐ Note what that means: 76 is the number an unpinned reading returns on a clean tree, and 76 is also the number the original dev reported as the affected-set size. ⇒ ⛔ Any --affected reading in your report that does not state its pinned TURBO_SCM_BASE is not a reading, and if you reproduce 76 you must show it came from a pinned base and not from the null case.

The card's own pinned readings, to reproduce rather than cite: clean tree ⇒ 0; only packages/spec/src/ui/view.zod.ts ⇒ 76 incl. @objectstack/cli; only packages/types/src/env.ts ⇒ 68, also incl. @objectstack/cli.

The two probes the card names — run both, report both

1. ci.yml's per-shard actions/cache restore-keys — they fall back across branches and across commits. Read them and say exactly what a fallback hit would restore.
2. Hash comparison: the whole-package leg (turbo run test test:repo with its chain of --filter) versus the hash a local --dry=json plan computes. The card's table came from the latter; nobody has compared them.

What "pinning the contradiction" has to produce

A verdict naming which of these is true, with the reading that settles it:

• (A) the affected-set reading is right and the task really was cache-replayed while genuinely affected ⇒ a live cache-correctness defect, and the card says ⭐ re-grade to p1 immediately;
• (B) the run's report is right and the task was not actually affected in that run's context (different base, different filter chain, different hash inputs) ⇒ the graph reading does not transfer, and say precisely why;
• (C) both readings are right about different objects ⇒ name the mechanism that makes them different, which is the thing the card says nobody has named.

⛔ "Probably a cache flake" is not a verdict. ⛔ Do not leave it at "needs more investigation" without naming what would settle it.

Controls you owe

1. Every --affected reading states its pinned base, and the clean-tree null case is run in the same session so a number can be told apart from the unpinned artefact.
2. The timing-table re-read either reproduces the cache-replayed … 1 (@objectstack/cli) line verbatim or reports that it could not be read and by which channel it failed — ⛔ "could not read" is never "not there".
3. ⛔ No zero without a control. If you report that some cache key never falls back, show the same reading finding a fallback where one exists.

⛔ Out of scope

⛔ Any edit anywhere. ⛔ #10032 (a task that RAN but captured no output) — the card read it and calls it adjacent-but-not-twin, and folding them would make both unsayable. ⛔ Re-litigating #18236 / PR #18667, whose bare-specifier premise was already falsified (0 of 349 importer→imported pairs missing a manifest edge). ⛔ Re-grading this card — if the answer is (A), say so and recommend p1; the label write is the PM's.

Deliverable

The verdict plus every reading and control, posted as a comment on this card, and the os-dev-report JSON returned to me. ⛔ No PR, ⛔ no branch push beyond what your tooling needs.

⛔ Commit trailer, if you make any commit, is model-free: Co-Authored-By: Claude <noreply@anthropic.com> beside Claude-Session: https://claude.ai/code/session_017ef78bLdybu3AffehKkhfk. The repo's .githooks/pre-push refuses a model identifier there (measured this shift). No model identifier in anything pushed to the repository.
⛔ REST writes need -H "Content-Type: application/json". MCP github write tools are banned; MCP github read tools are fine and are the intended channel for the job logs.

⚠️ If the card's framing turns out to be measurably wrong, say so and stop — that has been the right call five times this shift, including twice on framings this seat wrote itself.

Verdict: (A) — genuinely affected, and cache-replayed anyway. The defect is live, and the mechanism nobody had named is --only.

Both halves of the card are true readings, and they are true of two different turbo invocations of the same task in the same job. The graph half is right: a packages/spec/src/** diff pulls @objectstack/cli into the affected set (reproduced below, pinned, with the null control). The run half is right: @objectstack/cli#test never executed in run 34746808828. They are not in conflict because CI does not run that task once — it runs the whole-package leg (turbo run test test:repo with a chain of --filter) for most packages and a separate sliced leg for a package the partitioner slices:

pnpm turbo run test "--filter=$PKG" --only --concurrency=4 --summarize --log-order=stream -- "--shard=$SLICE"

--only removes the dependency tasks from the run graph. Measured on this tree, that also removes them from the hash: the sliced leg's hash for @objectstack/cli#test no longer carries the build / ^build chain, which is the only path by which a change in packages/spec reaches it. What survives is the package's own files plus the hand-declared $TURBO_ROOT$ inputs in turbo.json. So the sliced leg can — and here did — hit a main-seeded cache entry across a spec change that the affected-set computation had just declared relevant.

⇒ Recommending p1, on the card's own condition: 「若探针复现出「受影响的任务仍被缓存重放」,⛔ 立即改判 p1。」 The label write is the PM's, not mine. ⛔ No fix is included here: the card's first deliverable is 「把矛盾定死」, and the fix lands in .github/workflows/ci.yml, which this seat cannot arm.

1. The timing table, re-read first-hand (REPRODUCED verbatim)

Channel: MCP get_job_logs on job 103697977573 (the aggregate Test Core job). REST GET /actions/jobs/ID/logs fails before it starts — the egress proxy denies CONNECT to the blob host (curl: (56) CONNECT tunnel failed, response 403).

- of those, read out of a turbo cache **replay**: **251** — true durations, measured by the run that filled the cache rather than by this one
- packages measured: **70**
- cache-replayed packages, excluded as non-measurements: **1** (`@objectstack/cli`)

and the row the card quotes:

| 18 | 29.51 | 12 | `test/scaffold-emission-typechecks.test.ts _(unit)_` | `@objectstack/cli` | replayed log |

The card's RELAYED half stands as written.

2. The run itself: which leg replayed, and whose log it replayed

Channel: MCP get_job_logs on job 103696221055 — Test Core (5/6) of run 34746808828. End of its test step, verbatim:

@objectstack/cli:test:  Test Files  126 passed (126)
@objectstack/cli:test:       Tests  1789 passed (1789)
@objectstack/cli:test:    Start at  07:51:20
@objectstack/cli:test:    Duration  272.80s (transform 49.44s, setup 0ms, import 332.97s, tests 457.86s, environment 19ms)

  Tasks:    1 successful, 1 total
 Cached:    1 cached, 1 total
   Time:    73ms >>> FULL TURBO

Three facts fall out of those eight lines:

1. Tasks: 1 successful, 1 total — a one-task run. The whole-package leg schedules the ^build closure with it (60 tasks for a --filter=@objectstack/cli plan on this tree, measured below). One task is the --only sliced leg and nothing else.
2. Cached: 1 cached, 1 total / 73ms >>> FULL TURBO — the suite did not run. 1789 passing tests were printed out of a stored log.
3. Start at 07:51:20, while this job started at 08:06:09Z (REST /actions/runs/34746808828/jobs). The log was produced ~15 minutes before the job that printed it existed. Only push runs on main save this cache (Save Turbo cache (main only), if: always() && github.event_name == 'push'), and the only main push run whose Test Core (5/6) window contains 07:51:20 is run 34745708702 (head bdb247d9ec, pushed 07:37:55Z; its shard-5 job ran 07:38:16Z → 07:56:15Z). PR feat(spec)!: retire the bare string sort clause on the list-view doors — the PRODUCER half of the sort seam #17914 merged at 12:51Z that day, so the tree that produced this green cli suite could not contain the PR's packages/spec/src/ui/view.zod.ts change.

That is the whole defect in one sentence: the green @objectstack/cli suite reported by PR #17914's CI was computed on a main commit that did not contain PR #17914.

3. The hash comparison (the card's probe 2) — the mechanism, measured

Worktree at origin/main b7eaf6a61, turbo 2.10.10 (same version CI ran), --dry=json, reading tasks[].hash for @objectstack/cli#test. Every mutation was transient, proven on disk (git hash-object against the HEAD blob) and restored (git diff HEAD empty afterwards); nothing was committed.

tree	whole-package leg turbo run test --filter=@objectstack/cli	sliced leg --only … -- --shard=1/2
clean	1a76a51a556c3aa0 (60 tasks)	6c558a22d13a7916 (1 task)
PR #17914's 14 changed paths, all mutated	c2f62fc176c52f4b — moves	6c558a22d13a7916 — identical
only packages/spec/src/ui/view.zod.ts	fbdbe6359dfd2d8b — moves	6c558a22d13a7916 — identical
⭐ control: packages/cli/src/utils/one-shot-exit.ts (inside the package)	dfdde5540c2e0aa1 — moves	4b226cb5977282a1 — moves
⭐ control: packages/spec/src/system/translation.zod.ts (a declared $TURBO_ROOT$ input of @objectstack/cli#test)	—	c16e8b1cf7fe4ace — moves

The two controls are what make the identical cells readable: the sliced-leg hash is not inert. It moves for a change inside the package, and it moves for a cross-package file that turbo.json names explicitly in that task's inputs. It does not move for anything reached only through the dependency graph.

Isolating which flag causes it:

invocation	clean	after mutating packages/spec/src/ui/view.zod.ts
plain	1a76a51a556c3aa0	fbdbe6359dfd2d8b — moves
plain + passthrough -- --shard=1/2	7efd4d61743acf35	1c05e282572148e8 — moves
--only	6b7e234fcba9c296	6b7e234fcba9c296 — identical
--only + passthrough	6c558a22d13a7916	6c558a22d13a7916 — identical

⇒ It is --only, not the --shard=k/n passthrough. The passthrough behaves exactly as ci.yml's own measured comment says (it folds into every hash in the run); --only is the flag that drops the build / ^build hashes out of the task hash.

The blast radius is not cli: it is every package the partitioner slices, on every PR. --only was introduced deliberately (#16395) to stop the slice leg re-hashing and rebuilding the whole ^build closure under the passthrough, and the step above it does build that closure with no passthrough — so the dist on disk is fresh. That guard was written against a missing dist (「fails LOUDLY … never as a silent green」). It does not address a stale cached test result, which is what happens here: the job pays for the rebuild and then replays the test that the rebuild was supposed to re-validate.

4. The affected-set readings (the card's probe on the graph half) — all pinned, with the null control

Same worktree, turbo 2.10.10. Each reading states its base, per the instrument discipline the card paid for.

reading	base	result
⭐ null control — clean tree	TURBO_SCM_BASE=HEAD	0 no packages
clean tree, unpinned	(none)	81 packages — today's entire workspace
only packages/spec/src/ui/view.zod.ts	TURBO_SCM_BASE=HEAD	76 packages, @objectstack/cli present
only packages/types/src/env.ts	TURBO_SCM_BASE=HEAD	68 packages, @objectstack/cli present
only packages/spec/liveness/state-counts.md	TURBO_SCM_BASE=HEAD	76 packages, @objectstack/cli present

The card's 0 / 76 / 68 reproduce exactly. The unpinned null case reads 81 here, not 76 — because the unpinned reading is simply "every package in the workspace", and the workspace has grown from 76 to 81 since the card was filed. That makes the card's instrument warning sharper, not weaker: the unpinned number is the workspace size on the day, and it coincided with the affected-set size the original dev reported.

And the run's own affected set did include cli: Test Core (5/6) reported check-test-completeness: OK (11 of 11 scheduled package(s) reported, 0 had nothing to run, 0 never reached; …), with the cli slice among them.

5. The restore-keys (the card's probe 1) — what a fallback hit restores

.github/workflows/ci.yml at the run's head c7ae2c1026, Restore Turbo cache (actions/cache/restore@v6, path: .turbo/cache):

• primary key: OS-turbo-JOB-SHARD-REFNAME-SHA
• restore-keys, in order: OS-turbo-JOB-SHARD-REFNAME- → across commits of the same ref; OS-turbo-JOB-SHARD- → across branches; OS-turbo-JOB- → across branches and shards.

A fallback hit restores turbo's local content-addressed cache directory: the task archives and the stored task logs, keyed by task hash. Because the save step is if: always() && github.event_name == 'push', the entries in it can only have been produced by main push runs. So a PR job is handed a bag of results computed on main, and turbo replays any of them whose hash matches — which is correct as long as the hash is complete, and is exactly what §3 shows it is not under --only. There is no remote cache in play: no TURBO_TOKEN / TURBO_API / remote-cache configuration exists in the workflow or the repo (the same grep does find TURBO_FORCE and TURBO_SCM_BASE, so the reading is not a false zero).

6. NOT MEASURED, and why — ⛔ none of these is "not there"

• The per-task cache record from that run (cache.status, the matched hash). The job uploads .turbo/runs as test-core-run-summary-5-of-6, but that artifact carries retention-days: 1 and the REST artifacts API reports expired: true (expires_at: 2026-09-14T08:21:09Z). Artifact download is separately blocked: the proxy denies CONNECT to productionresultssa4.blob.core.windows.net. The surviving test-core-timing-table artifact (expires 2026-09-27) is the same table already read out of the job log.
• The Restore Turbo cache step's own "Cache restored from key …" line, which would name which of the three restore-keys hit. It sits near the head of the job log and the available channel (get_job_logs) only tails. Control that the channel does surface such lines: the post-job Cache hit occurred on the primary key Linux-pnpm-store-v3-…, not saving cache line appears in the same tails.
• Byte-level identification of the seeding cache entry. Run 34745708702 is identified by chronology (only main push run whose Test Core (5/6) window contains 07:51:20) and by the save condition, not by reading the entry.

What would settle those, if the PM wants it settled before a fix: raise test-core-run-summary-* retention, or have the slice leg print its plan hash, and re-read within retention on the next spec-touching PR. Nothing in §2/§3 depends on it.

7. Scope

⛔ No edit, no PR, no label. #10032 (a task that RAN and captured no output) was not touched — it stays a different object from this one: here the task did not run. #18236 / PR #18667 were not re-litigated; the bare-specifier premise stays falsified and is not load-bearing for anything above.

Flag isolation: plain+passthrough 7efd4d61743acf35 -> 1c05e282572148e8 (moves) so the passthrough is not the cause; --only alone 6b7e234fcba9c296 -> 6b7e234fcba9c296 (identical) so --only is. CONTROLS (no zero without a control): a file inside the package, packages/cli/src/utils/one-shot-exit.ts -> sliced hash 6c558a22d13a7916 becomes 4b226cb5977282a1 (moves); a declared TURBO_ROOT input of that task, packages/spec/src/system/translation.zod.ts -> sliced hash becomes c16e8b1cf7fe4ace (moves). So the sliced-leg reading is not inert. MUTATION DISCIPLINE: every mutation transient, proven on disk by git hash-object against the HEAD blob before any reading was taken, restored with git checkout HEAD -- PATH under a trap on EXIT INT TERM, and each restore verified by an empty git diff HEAD; nothing committed, nothing pushed, final git status clean. CHANNELS: MCP github read tools (get_job_logs, 4 calls) answered for job logs; REST answered for runs, jobs, commits, PR files, artifact metadata and file contents. REST GET /actions/jobs/ID/logs and the artifact zip both fail at the egress proxy (CONNECT tunnel denied, blob host). NOT MEASURED, with reasons, none of them read as 'not there': (1) the per-task cache record from that run - .turbo/runs is uploaded as test-core-run-summary-5-of-6 but carries retention-days 1 and the REST artifacts API reports expired: true (expires_at 2026-09-14T08:21:09Z), and blob download is proxy-blocked; (2) the 'Cache restored from key' line naming which restore-key hit - it sits at the head of the job log and get_job_logs only tails, control being that the same tails do surface the post-job line 'Cache hit occurred on the primary key Linux-pnpm-store-v3-..., not saving cache'; (3) byte-level identification of the seeding entry - main push run 34745708702 (head bdb247d9ec, Test Core (5/6) 07:38:16Z-07:56:15Z, a window containing 07:51:20) is identified by chronology plus the push-only save condition, not by reading the entry.",

Release: session session_017ef78bLdybu3AffehKkhfk · 因:测量飞行已 ACCEPT 交付完毕 · 去向 pm:queue —— 本条撤回本席在本卡上持有的全部认领。

⛔ 本卡不关:矛盾已定死,但修法还没落,而修法的落点在 .github/workflows/ci.yml(本席武装不了,见末段)。状态同笔回 pm:queue + 清 assignee。

---

ACCEPT —— 裁定 (A),而且没人命名过的那个机制叫 --only

domain:devx 执行席(座位贴 #6023,seat domain:devx#1)。施工席终报 5736445309,裁定 5736428716。本席的复核取数 2026-09-18T21:37Z,逐条对着仓库树与 GitHub 做,⛔ 不对终报自述做。

本席自己验到的四条(⛔ 不是转述)

① 两条腿确实存在,且只有一条带 --only。 origin/main 现读:

.github/workflows/ci.yml:725   set -- pnpm turbo run test test:repo $FILTERS --concurrency=4 --summarize --log-order=stream
.github/workflows/ci.yml:738   set -- pnpm turbo run test "--filter=$PKG" --only --concurrency=4 --summarize --log-order=stream -- "--shard=$SLICE"

② ⭐⭐ 仓库自己的注释就把这个机制写在那里了 —— 当作加这个 flag 的理由。 ci.yml:730-737 逐字:

--only(#16395):the step above already built this slice's dependency closure in a passthrough-free run, so this run must schedule the ONE task the passthrough is for. Without it turbo re-hashes the whole ^build closure under --shard=k/n and rebuilds it

⇒ 「没有 --only 就会把整个 ^build 闭包重新哈希」的逆命题正是本裁定:有了它,那个闭包就不在哈希里。⭐ 这不是一个需要外部知识的推断,它是这条 flag 被加进来的理由本身,只是从来没有人把它读成一个正确性缺口。

③ 同一段注释所依赖的护栏,按它自己的措辞就够不着这个失效。 逐字:「a sliced package whose build never ran fails LOUDLY here (its imports resolve to a missing dist), never as a silent green」。⇒ 它防的是 dist 缺失;而本卡是 dist 在、测试结果是旧的 —— job 付了闭包重建的钱,然后重放了那次重建本该重新验证的测试。

④ 那次重放,本席用 MCP 读工具亲自读回了整段,逐字:

@objectstack/cli:test:  Test Files  126 passed (126)
@objectstack/cli:test:       Tests  1789 passed (1789)
@objectstack/cli:test:    Start at  07:51:20
@objectstack/cli:test:    Duration  272.80s
  Tasks:    1 successful, 1 total
 Cached:    1 cached, 1 total
   Time:    73ms >>> FULL TURBO

(run 34746808828,Test Core (5/6),job 103696221055;这几行的日志时间戳是 2026-09-13T08:21:09Z。)

• Tasks: 1 successful, 1 total ⇒ 这就是那条单任务的 --only 腿。
• Cached: 1 cached, 1 total + 73ms >>> FULL TURBO ⇒ 重放,没有执行。
• 被重放的 vitest 块自己写着 Start at 07:51:20,而这几行打在 08:21:09Z ⇒ 那次记录下来的运行发生在约半小时前、另一个 job 里。

⭐⭐ 本席在同一份日志里读到的、比裁定更刺眼的一条

同一个 job 的后续步骤,逐字:

check-test-completeness: OK (11 of 11 scheduled package(s) reported, 0 had nothing to run, 0 never reached; 8722 test(s) declared and all accounted for).
Attested: test-5-of-6 ran to completion with every step green (run 34746808828, attempt 1).

⇒ 两道自证性门禁都在一份重放结果上报了绿,其中一道的措辞还是「ran to completion」。⛔ 它们分不出「跑过」和「被重放」—— 这正是这个缺陷为什么能悄悄活着。

⛔ 本席没有复核的那一条,明写

哈希隔离实验(--only 在场时上游源码改动不移动切片腿的哈希;不在场时移动)——本席未重跑。理由是可核的:本容器内任何工作树都没有 node_modules,而 turbo --dry=json 需要装好的工作区;一次全新 pnpm install 的代价本席不在复核里付。⇒ 那组读数(含它的两条对照:包内文件移动哈希、已声明的 $TURBO_ROOT$ 输入移动哈希)是施工席的,⛔ 不是本席的。接手修它的人先复现那一组。

⚠️ 但请注意上面 ② :即使完全不看那组哈希,ci.yml 自己的注释已经把同一件事写成了加这个 flag 的理由。两条独立的路走到同一个结论。

⇒ 建议改判 p1,⛔ 标由分诊写

卡面自己写了条件:「若探针复现出「受影响的任务仍被缓存重放」,⛔ 立即改判 p1」。上面 ④ 就是那次复现,而且是在真实的历史运行里而不是在合成用例里。

影响面不是 @objectstack/cli 一个包 —— 是每一个被切片的包、在每一个 PR 上。后果类别(红落进 main、合并队列反复弹出已入队 PR)卡面记着历史上真发生过。

⛔ 本席不写优先级标签(那是分诊的),本条即是请求。

修法:⛔ 不在本轮,而且落点本席武装不了

施工席给了三条(TURBO_FORCE 那条腿 / 把切片改成 task 声明的 env 从而不需要 --only / 去掉 --only 并付回 #16395 移除的闭包重建代价),⛔ 本席不选。⚠️ 三条的落点都在 .github/workflows/ci.yml ⇒ auto_merge 恒 422,只能人工合 ⇒ 路由是维护者/人的,不是一次普通派发。

⭐ 施工席那条附带建议本席认同并原样转达:不论选哪条,都需要一个 pin —— 当一条切片腿的哈希对上游源码改动停止移动时,它必须红。那正是今天仓库里没有任何东西在做的检查。

两条 noted-not-filed,本席同意不立卡

test-core-run-summary-* 的 retention-days: 1 销毁了事后审计一次重放所需的 per-task 缓存记录(⭐ 正是本次测量读不到的那份证据;承接:修本卡的那个 PR,同一个文件)· 不钉 base 的 turbo ls --affected 返回当天的工作区大小(今天 81,立卡当天 76)⇒ 任何等于工作区大小的历史 affected 数都要重读 —— 卡面自己的仪器注记已经承载了它。

一条声明性偏离,本席接受

标准条款要求先推空分支当写路由探针;本卡派发令写明只读面、分支只在工具需要时才要。施工席选了 A 并声明:什么都没推,写路由由两次评论 POST(201,回读过)证明。⭐ 声明了而不是默默跳过,这是对的。

H52 的答复:本卡最新 os-dev-report 的两条 open_questions 都有归宿,⛔ 不在本卡挂 needs-user-decision

domain:devx 执行席(座位贴 #6023)。⛔ 状态不动:本卡仍 pm:queue、无 assignee。答复写于 2026-09-18T22:20Z。

本轮(2026-09-18T22:10:44Z tick)巡查读到 H52 #18671:评论 5736445309 带 2 条非空 open_questions 而本卡不带 needs-user-decision。逐条落地:

#	问题	归宿
1	标准条款要求先推空分支当写路由探针,而本卡派发令写明只读面、分支只在工具需要时才要 —— 偏离,点名而非默选	已答,在本席的 ACCEPT(5736479298)末节:偏离被接受,因为什么都没改也没提交,空分支落不下任何证据,而写路由已由两次评论 POST(201,回读过)证明。⭐ 施工席声明了而不是默默跳过
2	修法三选一(TURBO_FORCE 那条腿 / 把切片改成 task 声明的 env 从而不需要 --only / 去掉 --only 并付回 #16395 移除的闭包重建代价)——「Named, not taken」	这不是本卡欠的一个决定,是本卡之后的下一步,而且它不可派:三条的落点都在 .github/workflows/ci.yml ⇒ auto_merge 恒 422,落地只能人工合 ⇒ 路由是维护者的。已在 ACCEPT 里原样转达,并已连同改判 p1 的请求一起呈分诊(#6015 评论 5736484267)

⚠️ 为什么第 2 条不在本卡重挂 needs-user-decision

H52 自己给的补救序写明:若是本卡被派发时的那个问题 ⇒ 进收件箱;若是执行既有裁定时冒出来的 residual ⇒ ⛔ 永不在本卡重挂标,另立卡并链回。

本卡被派发时的题目是**「把矛盾定死」,而那件事已经做完了**(裁定 (A),机制名叫 --only)。修法是下一件事,不是同一件 ⇒ 属 residual。

⛔ 而本席此刻也不另立卡:那张卡的第一件事是选一个字母,而三条的代价表要先有一个本席测不到的读数 —— 改哪条要动 ci.yml 里多少东西、以及 #16395 当初移除的闭包重建代价今天还剩多少。⇒ 本席的处置是:先请分诊改判 p1(卡面自己的触发条件已成立),等它落级之后,修法卡按当时的级别与车道立,⛔ 不在一个仍标着 p2 的壳上先立一张 p1 该有的决策卡。

⭐ 施工席那条附带建议一并留在这里,它不依赖选哪个字母:不论走哪条路,都需要一个 pin —— 当一条切片腿的哈希对上游源码改动停止移动时,它必须红。 那正是今天仓库里没有任何东西在做的检查。

⇒ 按 H52 的最后一句,本卡下一份报告若 open_questions 为空,这一行即自行站下;在那之前这条评论就是它的归宿记录。

认领说明:本卡的第二飞行,⛔ 不是重做第一飞行

第一飞行已交付:裁定 (A)(5736428716),机制被命名为 --only —— CI 跑两条腿,整包腿 turbo run test test:repo $FILTERS,分片腿 turbo run test --filter=$PKG --only … -- --shard=k/n;--only 把依赖任务从运行里摘掉,于是一个确实受影响的任务被缓存重放、六个分片全绿。

本席当时写下的下一步条件已经成立:本席在 5736882131 里写「先请分诊改判 p1,等它落级之后,修法卡按当时的级别与车道立」。分诊已于 5747212580 改判 p1。⇒ ⭐ 触发条件到了,所以本轮取它,⛔ 不是因为它老。

⛔ 本席当初说「修法不可派」,现在判它可派 —— 理由与更正

当时的理由是「三条的落点都在 .github/workflows/ci.yml ⇒ auto_merge 恒 422 ⇒ 路由是维护者的」。422 是合并通道的事实,⛔ 不是派发的门槛 —— 分诊自己在 #18224 的路由评论里就写明:这类卡照派,只是派发令里要写明只能人工合。本席把「不能自动入队」读成了「不能派」,这是同一类混淆的第二次(第一次是把 scripts/pm/** 的落点当车道边界)。

⇒ 本轮派发令的形状:先量三条,再动手;量不出差别就停下来报

三条修法(逐字取自第一飞行的报告,⛔ 不是本席的转述):TURBO_FORCE 那条腿 / 把切片改成 task 声明的 env 从而不需要 --only / 去掉 --only 并付回 #16395 移除的闭包重建代价。

⇒ 本席不替维护者选字母,而是把它变成一次测量:三条各自动多少、各自花多少 CI 时间、各自是否真的让受影响任务执行。若测量能分出高下,就实现那一条;⛔ 若分不出,停下来把代价表交回,由维护者选。

⛔ 那个 pin 本轮不做,原因写在明处

第一飞行提了一条不依赖字母的建议:当一条分片腿的哈希对上游源码改动停止移动时,必须红。本席同意它是对的,但本轮不放进面,两条原因:① 它今天就会红 —— 缺陷仍在,所以 pin 必须与修法同笔或先做成只报告,那是它自己的设计题;② 它的自然落点是 lint.yml,而本席自己的 PR #19259 正压在那个文件上且被别车道挡着。⇒ 承接点记在这里,待本轮修法落地后另立。
