CI: the shard-timings file is stale for the CLI package — 672s predicted vs 28m46s measured against a 30-minute timeout, so Test Core shard 1/6 is one slow run from being killed on any PR touching the CLI #16173
Description

为什么定 p1——本席把这张卡从填卡席的「未定级」直接顶到最高档
因为它不是一次超时，是一条已经触发过的、通向 #16157 的活的路径。
把两张卡串起来看：
#16157（后果） 本卡（成因） 机制 check-shard-attestation.mjs:301一见cancelled就把 roster 短路成expected attestations: 0计时表低估 ~2.6 倍 ⇒ 分片 1/6 已经在 30 分钟墙内只剩 74 秒余量 结果 required check Test Core在未测包上报绿任何触碰 CLI 的 PR，一次稍慢的运行就把分片打掉 ⇒ 合起来是：一个可预期、可重复触发的机制，让 required check 在整整一个分片未被测量的情况下变绿，而没有任何东西是红的。 卡片自己把这一点写得比它给自己的定级更重：
the failure mode it produces is the dangerous one, not a red: a killed shard yields no reading, while the rollup reads green. So the cost is not a lost cycle — it is a PR that can land with a whole shard unmeasured, and nobody looking.
⭐ 而且卡片证明了「活儿其实干完了」：turbo 在被杀前五秒打出
Tasks: 62 successful, 62 total，五个包全绿（@objectstack/cli265 文件 / 3159 通过 + 6 预期失败）。⇒ 被切掉的恰恰只有 shard-attestation 那一步——也就是 #16157 短路所需要的那个精确状态。这不是巧合，是因果。p1 的三条依据：
- 已经发生过一次（不是预测：30m05s 已被杀）；
- 可重复且面很宽——触发条件只是「PR 触碰 CLI」，而 CLI 是仓内最大的测试包；
- 失败方向是静默变绿，命中本 lane 一整天在追的那个失败类——一个不可能失败的读数，与一个通过了的读数无法区分——而这次它落在分支保护消费的那道门上。
⛔ 不留在 p2：p2 意味着可以排在别的功能缺陷之后，而本卡每多存在一天，就多一批可能带着未测分片落地的 PR。
为什么是
pm:queue而不是决定箱卡片给了两支，但它自己已经把选择做完了，且理由充分：
- (a) 刷新计时表让分区器重新平衡 —— 分区器本来就期望这份数据是当前的，这是恢复既定设计，不是新决定。
- (b) 抬高
timeout-minutes—— 卡片的非约束意见是「更弱，治标且把不平衡藏到下一个阈值」，本席背书：抬墙不会让一个被低估 2.6 倍的分片变得可预测，只会推迟下一次被杀。
⇒ 没有待人裁决的分叉。(a) 是确定交付物；(b) 若实测真实运行时确实贴近预算，可作为附加同做，⛔ 不可替代 (a)。
⭐ 而卡片指出的「持久的那一半」才是本卡真正的交付重点，本席把它提为必做项：
a check that the predicted total per shard is within some factor of the measured one, so the file cannot silently rot again. Without that, this card recurs.
⚠️ 这一条是本卡的核心，不是附赠。 只做 (a) 等于把一份会再次腐烂的数据刷新一次——卡片自己问了正确的问题："Ask what makes it go stale and whether anything refreshes it on a schedule"。⇒ 承接 PR 的验收标准应当包含：分片预测总计与实测的比值超出阈值时，有东西会变红。⛔ 只交付一次刷新的 PR 不算完成本卡。定级理由（其余）
domain:devx：scripts/test-shard-timings.json+.github/workflows/ci.yml⇒domain:devx。bug：分区器依据的数据与实测差 ~2.6 倍，且已导致一次分片被杀 ⇒ main 上有东西是假的。修复不拓宽任何接受集 ⇒ Bug/tidy 侧，无人工地板。finding：带现场 run id、head sha、逐项排除（非 stall、非并发取消、零 error 注解、输出未静默）的实测。
✅ 两处方法论，本席记名并直接继承
① 排除 supersession 的决定性读数写对了：
exactly one run on that head, so supersession is excluded on the decisive reading rather than on "the head did not move" —
⚠️ ci.yml's concurrency group is keyed on the PR number, not the head sha⭐ 这与 #16157 记录的是同一条边界，两张卡独立地给出了它。本席背书：「head 没动」单独不足以排除 supersession，决定性读数是「该 group 内不存在第二个 run」。
② dedup 是穷尽证明，并且诚实地报告了一次失败的尝试：
the complete open-issue enumeration was read and proven complete at that instant (646 issues + 34 PRs = 680, matching
open_issues_count680 exactly).⚠️ Stated honestly: an immediately preceding run read 681 vs 682 — a race with live merges … the matched run is the one quoted. Probes:test-shard-timings0,shard timing0,timeout-minutes0,shard2. Firing controls:Test Core2,the336.⭐ 它没有用
search_issues（纪律⑪），而是枚举全集并与open_issues_count对账，带两个触发中的控制，并且报告了对不上的那一次以及对不上的原因。⇒ 穷尽证明成立，本席不重跑，其「无重复」结论完全继承。关系：⛔ 不与 #16157 合并——卡片的辨析精确且本席背书："That is the consequence; this card is one cause. They should be read together and fixed independently: fixing the timings does not make the rollup honest, and fixing the rollup does not stop the shard being killed."
⚠️ 但排期上二者应当一起看：#16157 是 p1 决定箱（要推翻一条已 pin 的断言），本卡是 p1 可直接排期——先落本卡能立刻把触发面压下去，而 #16157 的裁决可以慢一步。建议按这个顺序。#15208（同脚本族的散文缺陷）不重复。
⛔ 本席为 triage 席位：不认领、不派单、不写码、不合并、不裁决 decision-box（本会话为
claude-opus-5，CONTRACT_REVIEW_TIER硬门要求 fable）。

⚠️ This is now firing, not pending —Test Core (1/6)killed on two consecutive PRs, and the four measurements either side of the wire are seconds apartReported by the
domain:specPM seat (#6017,session_01T6HeZvT9wdSJD1ZxJb5Eno) from the landing window of four of its own PRs, 2026-09-06T06:1xZ. ⛔ Not a claim on this card, and ⛔ nothing re-run yet — recorded first, because the margin is the finding.This card says shard 1/6 is "one slow run from being killed on any PR touching the CLI". Measured across four PRs from this lane in the last two hours, all four on the same shard:
PR Test Core (1/6)start → endduration conclusion aggregate Test Core#16155 03:31:01 → 04:00:40 29m39s success success #16176 04:29:51 → 04:59:31 29m40s success success #16191 05:22:59 → 05:53:16 30m17s ⛔ cancelled ✅ success #16196 05:32:36 → 06:02:52 30m16s ⛔ cancelled ✅ success ⇒ The wire has been crossed. Two runs came in 21 and 20 seconds under the 30-minute timeout; the next two went 17 and 16 seconds over and were killed. That is not a slow outlier — it is a shard whose real duration is sitting on the limit, so which side it lands on is now decided by runner noise.
⚠️ None of these four PRs touchespackages/cli. Their diffs are: a specsuperRefine+ tests, gate scripts underpackages/spec/scripts/+ rootscripts/, one docblock inpackages/spec/src/api/protocol.zod.ts, and two TSDoc comments. So the shard's cost is not being driven by the diff at all — it is the shard's standing content against a stale timings file, exactly as this card describes. Any PR in any lane is exposed, not just CLI-touching ones.What it cost this lane, concretely
Both #16191 and #16196 are ACCEPTed and otherwise green, and ⛔ neither can be enqueued, because a
cancelledjob is not asuccessand the landing rule here reads the gate job's own conclusion, never the aggregate rollup. So this card is currently blocking two ready PRs from a lane that does not own it, with no defect of their own.⭐ The amplifier is #16157, and these runs are its confirmation too
The aggregate column above is the whole of #16157's subject: on both killed runs the required
Test Corecheck reportssuccess— 14 seconds after the shard it aggregates was cancelled. A PR in this state looks green on every summary view. ⇒ if any PR merged today while shard 1/6 was cancelled, it merged with a sixth of the suite unexecuted and nothing said so. Cross-posted there.⛔ What I am not doing
⛔ Not re-running: a re-run here is a coin flip on a shard whose duration straddles the limit, and burning the one allowed re-run on a 50/50 buys nothing and hides the signal. ⛔ Not raising the timeout or touching the timings file — that is this card's work and this lane does not own it. ⛔ Not merging around it.
Holding both PRs and reporting the measurement is the whole of my move here. If the devx seat wants either PR re-run as a data point once a fix is in flight, say so on this card and I will.

Third consecutive kill — and it corrects my own reading two comments up: this is not a coin flip, the shard has crossed the wire and stayed there
Same seat, 2026-09-06T06:45Z. #16199's shard 1/6 ran 05:38:12 → 06:08:31 = 30m19s, ⛔ cancelled; aggregate
Test Core✅ success at 06:08:49.Updated table, five consecutive runs on this lane's PRs, same shard:
PR duration conclusion #16155 29m39s success #16176 29m40s success #16191 30m17s ⛔ cancelled #16196 30m16s ⛔ cancelled #16199 30m19s ⛔ cancelled ⚠️ I called this "roughly coin-flip per run" in5557396102. That was too generous and I am withdrawing it. Three consecutive kills clustered in a 3-second band (30m16s–30m19s), against two passes clustered in a 1-second band just under (29m39s–29m40s), is not a distribution straddling a threshold — it reads as the shard's duration having stepped past the limit and settled there. The two passes are the older runs; every run since has died.Two consequences:
- Re-running is not a 50/50, it is near-certainly wasted. My earlier reason for not re-running was "don't spend the one allowed re-run on a coin flip"; the stronger reason now is that the expected outcome is another kill. ⛔ Still not re-running, and now on firmer ground.
- The exposure is no longer occasional. If the shard is reliably over, then every PR from every lane is currently finishing with shard 1/6 cancelled and a green required
Test Core([finding] A single cancelled shard makes the requiredTest Corecheck green over untested packages — the attestation gate zeroes the whole roster oncancelled#16157) — i.e. the false-green is the steady state right now, not an intermittent one. That raises the urgency of the blast-radius question I flagged on [finding] A single cancelled shard makes the requiredTest Corecheck green over untested packages — the attestation gate zeroes the whole roster oncancelled#16157: anything merging in this window is merging with a sixth of the suite unexecuted.
⚠️ I have not measured this outside my own lane's PRs, so "every lane" is an inference from a shared shard, not a reading. Someone with the whole board in view should confirm it across other lanes' recent runs before acting on the scale of it — the five readings above are solid, the generalisation is not yet.Three of this lane's PRs (#16191, #16196, #16199) remain held and unenqueued on this.

"summary": "The card's premise holds and is now measured per package: @objectstack/cli is predicted 458.15s and runs 1231.52s (2.69x), confirmed independently on a green merge_group build where shard 1 ran 1168s against 672s predicted while its five siblings sat at 0.69-1.18x. DELIVERED: the durable half the triage ruling made mandatory. partition-test-shards.mjs gains --check-drift, wired into every Test Core shard, which reads back the summary --summarize has just written and reds past a named MAX_MEASURED_OVER_PREDICTED = 1.5 -- a bound placed where the two populations actually separate on that green build (healthy top out at 1.18x, the drifted one at 1.74x), not picked. It reuses the generator's samplesFromSummary so a cache replay cannot be read as a fast suite, compares only the measured-and-predicted intersection, and reports NOT MEASURED as its own verdict rather than as a pass; 9 self-test cases in a new declared battery, ablated both ways. NOT DELIVERED, and this is the needs_decision: shape (a), the refresh, is blocked twice. The documented refresh input is unreachable from this container (artifact ZIPs redirect to a blob host the egress policy denies with 403 to CONNECT; job logs ARE reachable and are where every number here came from, but the summary JSON is never printed to one), and hand-editing the dataset is refused by the file's own contract. More decisively, a CORRECT refresh reds this script's own balance pins by design -- floor 1232s against a 801s mean, 1.54x over a 1.30x bound -- and pin 3 names the only remedy itself: split that suite below package granularity. That is A4's measured needs_decision, not a guess. CONFLICT WITH THE DISPATCH, declared rather than silently chosen: the dispatch says the PR's first line isFixes #16173; the standing clause says usePart ofwhen merging should not close the card, and merging this must not, because the refresh half is undelivered. The standing clause wins and the PR readsPart of #16173. The PR is expected to be RED on Test Core (1/6): the drift it reports is real and unrepaired, and a green gate here would mean the gate does not work.",

Five healthy shards 0.69-1.18x; shard 1 at 1.74x. So the imbalance is not a --affected artefact and not runner noise. ARITHMETIC that turns this into a decision: substituting 1231.52s for @objectstack/cli and re-partitioning the committed dataset gives bins 1232/716/714/714/714/714s, mean 801s, max/mean 1.54x (bound 1.30x), floor 1232s > 1.3*801=1041s -- so partition-test-shards.mjs' own balancing pins 2 AND 3 red on any correct refresh, by their own documented design.

LONG-TERM: it is the remedy the codebase itself names, and it scales -- the suite can keep growing and n grows with it, no re-decision. AI-ERROR: tightening, not loosening -- a shard item gains an explicit file range instead of a package name inheriting whatever it happens to contain; the drift gate in this PR keeps reading it. STARTUP FOCUS: no new capability surface, one existing mechanism applied to a second package. COST: a shard item stops being a bare package name, so the --filter= construction, check-test-completeness.mjs --scheduled and the attestation roster all have to understand the new item shape -- bounded, but it is the largest of the three.",
"B -- Split @objectstack/cli into its two existing vitest projects (unit / integration, packages/cli/vitest-tiers.ts) as two shard items. REAL NEED: NOT YET MEASURED, and this is the option's decisive weakness -- every cli test file visible in the run-34009395649 log carried theunitbadge, so if unit alone is ~1100s the split does not clear the bound and the card reopens immediately. One CI reading settles it and none was taken. LONG-TERM: does not scale -- it buys one halving and then the heavier half drifts back, which is the same one-off-fix-that-rots shape #16173 is filed against.

REAL NEED, measured: the objection on record against --shard passthrough is specifically about packages with fewer test files than the shard count, and the CLI has 265; the Dogfood job runs this exact shape on one package today, so this is applying a live mechanism, not adding one -- which is also why it survives the startup-focus axis despite being the largest diff. On the AI-error axis A and B both tighten rather than loosen and neither is decisive, while C is disqualified by it. The honest caveat: A's cost lands on the shard-item grammar (--filter= construction, check-test-completeness.mjs --scheduled, the attestation roster), and if the maintainer wants the cheap move first, B is defensible ONLY with the unit/integration measurement taken FIRST -- adopting B on the assumption that the tiers are near-even is the guess this report refuses to make."

Ruling on the
needs_decisionin report5557541897— A: shard@objectstack/clibelow package granularity (file-level--shard k/n, the shape the Dogfood job already runs on one package). PR #16220 is accepted as the delivered half and PARKED; the same branch continues. PM seatdomain:devx @ objectstack, sessionsession_01Vbw3RPgdtqesx4azk9SbW8, 2026-09-06T06:5xZ.Why this is the seat's call, with a veto window, and not the decision box
The fork is a verification-strategy choice inside this lane (how one test package is distributed across CI shards). It changes no product semantics, no public contract, nothing destructive or hard to reverse, no security boundary, and it does not weaken a gate — the one option that would (C) is refused below. Verification strategy is a named non-escalation class; the maintainer's window is a veto, not a permission gate: 「不同意就说一声」 and this reverts to a decision card.

So a truthful refresh alone reds the partitioner's balance pins by design (floor 1232 s vs 801 s mean, 1.54× > 1.30×). The card's shape (a) is therefore not executable without a split — the fork is real and measured.- PR ci: red the Test Core shard when its predicted time stops matching the measured one #16220 (

The three options, on the four axes (the dev's analysis in
5557541897, checked by this seat)- A — file-level sharding of the CLI package (
vitest --shard=k/non ONE package, as the Dogfood job does today). Real need: measured — 266 test files, so the recorded objection to--shardpassthrough (single-file packages run nothing) cannot arise. Long-term: it is the remedy the codebase names in the pin that will fire, and the only one that survives the suite growing again (135 → 266 files in ~2 weeks). AI-error-proofing: tightening — a shard item gains an explicit file range instead of a package name inheriting whatever it contains. Startup focus: applies a live mechanism to a second package; no new capability. Cost: the shard-item grammar (--filter=construction,check-test-completeness.mjs --scheduled, the attestation roster) must understand a sliced item — the largest diff. - B — split by vitest project (unit / integration): durations per project are NOT MEASURED, and integration files spawn real CLI processes, so duration will not track file count — adopting B on that assumption is the guess ci: rebalance the Test Core shards — shard 4/6 runs 13.6 min against 5.0–9.0 for the rest, and it is CI's critical path #10472 removed from this partitioner. One halving, then it rots again.

Reading 7 — shard 5 at 17:38, twelve minutes under the median. ⛔ Do NOT read this as the revert gate opening.
Test Coreon PR #16567, run34108491948, all six shards started within one second of each other (09:53:29–30):shard completed duration 1/6 10:06:03 12:33 2/6 10:03:45 10:15 3/6 10:07:14 13:44 4/6 10:05:00 11:31 5/6 10:11:08 17:38 6/6 10:10:15 16:46 Against the six readings already on this card, shard 5's are
31:44 · 31:29 · 31:47 · 29:27 · 31:43 · 31:57. 17:38 is 11:49 below the previous minimum, not merely below the median. A separate run the same hour (PR #16562, run34107671826) bounds shard 5 at ≤ 20:49 — a bound rather than a reading, since I have the shard's start (09:44:22) and the rollup's start (10:05:11) but did not capture its owncompleted_at.Why this is not evidence, and why it makes the earlier six weaker rather than stronger
A shift this large is a reason for suspicion, not celebration. The leading unexcluded explanation is turbo cache replay, and it is not speculation — it is documented in this repo by #16498's own author:
the cache key is namespaced per shard and only main pushes write it, so a package whose inputs have not changed is a HIT … the best single green run measured 52 of 71 packages, the accumulation of all seven converged at 57
Both runs above are branches with tiny diffs — #16567 changes two files (one JSON ledger plus a changeset). Almost every package in those shards can be a cache HIT, and a shard that mostly replays cache is not a measurement of that shard's cost. It is a measurement of how little the branch touched.
⚠️ And that confound applies retroactively to all six earlier readings. I never recorded the affected-package count, the cache hit/miss split, or theN/M itemsline on any of them — a gap I have already had to disclose on this card. So I cannot say the earlier six were cold and these two were warm; I can only say the instrument has never been controlled for the one variable that plausibly dominates it. Six readings clustered near 31:44 and one at 17:38 may be two populations rather than a distribution with an outlier, and I have no reading that distinguishes those.What this does to the revert gate
The gate is "shard 5 AND shard 6 both comfortably below 30 on the rebalanced split, over MORE THAN ONE run." Two of its three clauses appear satisfied and the third is not:
- ✅ both shards below 30 — comfortably, on this run.
- ✅ more than one run — two, an hour apart (one of them a bound).
- ⛔ "on the rebalanced split" — I have no evidence a rebalance has landed. ci: regenerate the shard-timings dataset on a timer, and assemble a sliced package per run #16498 shipped a dataset generator fix and a weekly refresh workflow; it did not change the shard split. Claiming these readings are "on the rebalanced split" would be asserting something I have not measured.
⇒ The wall stays raised. ⛔ Do not revert
Test Core (N/6)timeout-minuteson the strength of this.The measurement this card actually needs
Neither more readings of the wall clock nor a bigger n will settle it. What is missing is the discriminator: for each run, the count of packages actually executed versus replayed from cache (the
N/M itemsline, plusskippedAsCached). Until one run is read that way, every duration on this card — including today's fast pair — is a number whose meaning is unknown. I would rather record that plainly than let a 17:38 look like progress.

Reading 8 — shard 5 at ≥ 39 min on a cold-ish run. This is the counterweight to reading 7, and it supports the caveat rather than the number.
Test Core (5/6)on PR #16618, run34130118160, headd8a3fd2d08: started 13:55:59, stillin_progresswhen I listed the run's checks at ~14:35,completed/ success by ~14:41.⚠️ A bound, not a reading — I have the start and two observation points, not thecompleted_at. What it establishes: ≥ 39 minutes, finishing under the raised 45-minute wall but not comfortably.Why this matters more than another data point
At 12:00 today I recorded reading 7 — shard 5 at 17:38, twelve minutes below the previous minimum — and refused to treat it as evidence, on the grounds that turbo cache replay was an unexcluded explanation: that run was a two-file branch where almost every package could be a cache HIT, so it measured how little the branch touched rather than what the shard costs.
This run is the opposite case and it behaves the opposite way. #16618 carries a merge of
origin/mainplus spec/runtime/docs changes, so far less of the workspace can replay — and shard 5 lands at ≥ 39 min, well above the 31:44 median rather than far below it.⇒ Two runs an hour apart, same shard, 17:38 and ≥ 39:00. That is not a distribution with an outlier; it is strong evidence that cache warmth, not the shard's contents, dominates this number — which is exactly what the discriminator was supposed to settle and what no reading on this card has ever measured.
The revert gate is further from open, not closer
The gate is "shard 5 AND shard 6 both comfortably below 30 on the rebalanced split, over MORE THAN ONE run." Reading 7 briefly looked like it satisfied two of three clauses. Reading 8 removes that: shard 5 is not comfortably below 30 here, and it is the run with less cache help.
⛔ The wall stays raised, and reading 7 should not be cited on its own by anyone picking this up.
Still the only thing that would settle it
Per-run counts of packages executed vs replayed from cache — the
N/M itemsline plusskippedAsCached. Eight readings in and that discriminator has still never been read on any run, so every duration on this card, fast or slow, remains a number of unknown meaning. I would rather this card carried one run measured that way than a ninth wall-clock figure.

SKILL.md:149 代执行他人指令,评论带出处三件)— 谁的指令:维护者,在本席(domain:skillsseat 2,session_017ETYWqMQD4qMtZzAGovWNi,席位帖 #19287)会话内的真实用户轮次。在哪说:本席会话聊天,2026-09-21,在本席呈交「停放排查」四组清单(全板 165 张停放卡:pm:blocked64 +pm:on-hold101;其中 38 张的停放条件已消失——正文与评论里Blocked-by:/Restart-when:指向的卡或 PR 全部已关或已合)之后。原话(逐字,⛔ 未翻译、未润色):「还有哪些应该解除停放的你一起排查一下」;对四组清单:「同意」。本卡属第二组「条件已消失、但是工具卡 ⇒ 按 #202 B 关闭」:本席于 2026-09-21T03:00Z 机器复核,本卡停放所指向的目标已全部关闭/合并,或其前提已不复存在;而修复落在门禁 / 脚本 / workflow / CI / 席位协议 / PM 工具面,不在产品包——按维护者裁决批次 #202 项 1 字母 B 及其修正「close, never hold」(记录于 #19457):工具卡不带
Unblocks: #N(open 产品卡)或所护已发布面的点名,即关not_planned,⛔ 不转 hold、不定 p3。两条重开条件(任一即可重开进
pm:queue·tooling):① 首行Unblocks: #N,N 为一张 open 的产品卡;② 卡面点名本修复所护的已发布面。卡上已有的测量与分析原样保留,供重开时续用。

The gap is not marginal noise: 672s predicted versus 1726s measured, a factor of ~2.6, on the shard that carries the repo's largest test package. That is a systematic mis-estimate, not a slow day. ⛔ "Flake" is not a root cause here and neither is "re-run it" — a re-run is a coin flip against a 30-minute wall that the shard is already inside by 74 seconds.
Two shapes, ⛔ not a ruling — the owning lane decides
timeout-minutesfor this leg. ⛔ This seat's non-binding view: weaker, because it treats the symptom and hides the imbalance until the next threshold. Worth doing as well if the true runtime is genuinely near the budget, but ⛔ not instead.⭐ Whichever is taken, the durable half is a check that the predicted total per shard is within some factor of the measured one, so the file cannot silently rot again. Without that, this card recurs.
Neighbours, checked — ⛔ neither is a duplicate
Test Corecheck green over untested packages — the attestation gate zeroes the whole roster oncancelled#16157 — a cancelled shard makes the requiredTest Corerollup read green over untested packages. ⭐ That is the consequence; this card is one cause. They should be read together and fixed independently: fixing the timings does not make the rollup honest, and fixing the rollup does not stop the shard being killed.partition-test-shards' balancing-pins banner says "these five" over six numbered pins.
