ci: shard-timings-refresh 的写回步骤缺两个 env 变量,每周定时刷新在算完之后死于 RUN_COUNT: unbound variable —— 数据集已 22 天未动,而 pull_request 演练结构上跑不到这条腿

.github/workflows/shard-timings-refresh.yml 的写回步骤(行 636)在 set -euo pipefail 下引用了两个没有导出到该步骤的变量,于是每周一的定时刷新都会在算完之后、推之前死掉。⇒ scripts/test-shard-timings.json 自 2026-08-24 起未动过,22 天。

⚠️ priority: 与 domain: 故意留空 —— 分诊的活,不是本席的。
⚠️ 本卡改 .github/workflows/** ⇒ 受管面,席位 auto_merge 恒 422,只能人工合(与 #18096 / #18224 同一堵墙)。

根因 —— 行 653 用了 `$RUN_COUNT` 与 `$RUNS`,行 638–641 的 `env:` 只给了两个

636  - name: Push the refresh branch and open the pull request
637    if: steps.compare.outputs.changed == 'true' && github.event_name != 'pull_request'
638    env:
639      GH_TOKEN:  ${{ secrets.RELEASE_PUSH_TOKEN || github.token }}
640      RUN_ID:    ${{ steps.generate.outputs.run_id }}
641      HEAD_SHA:  ${{ steps.generate.outputs.head_sha }}      ← ⛔ 没有 RUNS,没有 RUN_COUNT
642    run: |
643      set -euo pipefail                                       ← -u 就是执行判决的那个字母
...
653        -m "… artifacts of $RUN_COUNT accumulated run(s) ($RUNS), newest $RUN_ID at $HEAD_SHA. …"

发火对照,同一文件同一批 outputs:紧邻的「Compose the pull request body」步骤(行 522)把四个全导出了:

524    env:
525      RUN_ID:    ${{ steps.generate.outputs.run_id }}
526      RUNS:      ${{ steps.generate.outputs.runs }}        ← 这两个在这里有
527      RUN_COUNT: ${{ steps.generate.outputs.run_count }}   ←
528      HEAD_SHA:  ${{ steps.generate.outputs.head_sha }}

⇒ 四个 output 都存在、都可导;⛔ 不是 generator 少产了值,是写回步骤漏抄了两行。

实测 —— 唯一一次定时运行的日志(run 34810389734,2026-09-14T05:38Z)

前面每一步都绿,数据集是算出来了的:

 8  Self-test the generator and the run selector            success
10  Choose a green, uncensored, un-replayed run             success
11  Regenerate the dataset, accumulating runs until …       success
12  Compare against the committed dataset                   success
13  Predicted bins, before and after                        success
14  Compose the pull request body                           success
15  Push the refresh branch and open the pull request       FAILURE   ←
16  Dry run — the pull request this would have opened       skipped

日志末两行,逐字:

2026-09-14T05:40:01.8347096Z ##[error]Process completed with exit code 1.

分支切出来了、git add 也过了,死在 git commit 拼消息体那一行。

⭐ 为什么合入前的演练抓不到它 —— 推送路径结构上跑不到

工作流头注写着本车道「改动在合并前先演练」。演练确实跑了,但它跑的是另一条分支:

行 637  写回步骤    if: … && github.event_name != 'pull_request'
行 690  演练步骤    if: … && github.event_name == 'pull_request'

⇒ 在 pull_request 上,写回步骤永远 skipped。实测四次运行的分派:

run 7  schedule      failure   ← 写回步骤唯一一次真跑,就是它死的那次
run 6  pull_request  success   ← 步骤 15 skipped,步骤 16 success
run 5  pull_request  success   ← 同上
run 4  pull_request  failure   (别的原因)
run 1  pull_request  failure   (别的原因)

⇒ 写回路径的首次执行就是 2026-09-14 那次定时运行。演练与被演练的是互斥的两条腿,而合并门只看得见其中一条。

影响 —— 一张 p1 卡正卡在这个通道上

scripts/test-shard-timings.json 在 origin/main 上的最近两次改动:

e75e34381  2026-08-24  fix(ci): … shard timings re-measured (#11868)
7c9e5a59b  2026-08-21  ci(test-core): balance the Test Core shards on measured suite duration …

⇒ 22 天没动。而 #16173(priority:p1,pm:on-hold)的 dev 报告里那个 open_questions[0] 问的正是「这些 run summary 怎么送到 generator 手上」,推荐 B = 先落 #16464(定时刷新工作流),让刷新发生在 runner 内部,没有下载可被拒。

B 已经落了 —— #16464 closed completed,shard-timings-refresh.yml 就在 origin/main 上。⛔ 但它从未交付过一次刷新。⇒ #16173 等的是一个已经建好、却在最后一米静默失败的通道。

验收(⛔ 不规定实现)

让写回步骤拿到它引用的每一个变量。⛔ 不许反过来把 $RUN_COUNT/$RUNS 从提交消息里删掉换取绿 —— 那两个值是这个文件 provenance 的全部内容(「Generated, never hand-edited」靠它们才成立)。
⭐ 两个方向都要量:构造缺一个变量让它红,补齐让它绿。⛔ 只证补齐后绿不算。
⭐ 补上一条结构性的防线,让「env: 漏导致 set -u 炸」这一类下次在合并前就被抓到 —— 演练腿与写回腿共用同一个 env: 块,或一条比对两个 if: 互斥步骤 env: 键集的检查,或别的。⛔ 本卡不指定哪一条,但只修那两行不够:同一个形状在这个文件里还有第二处的可能没被排除(⛔ 本席没查)。
修完触发一次 workflow_dispatch,拿到一个真开出来的 PR 作为验收读数。⛔ 「下周一等着看」不是验收。
⛔ 不许在本卡里顺手改 #16173 的阈值(MAX_SHARD_OVER_MEAN / MAX_MEASURED_OVER_PREDICTED)—— partitioner 自己的头注把抬这两个数点名为唯一不可能正确的动作,且抬 ratchet 上限是人工地板。

⛔ 没量的部分,不许当读数用

⛔ 没跑过修复,也没跑过 workflow_dispatch。 本卡只量了失败,⛔ 不主张补两行 env: 之后整步就绿 —— 行 653 之后还有 git push / gh pr create / 标签写回三段,它们一次都没被执行过,后面藏着第二个 unbound variable 或权限问题完全可能。
⛔ 没审这个文件其余 716 行里有没有同形的 env: 漏项。抽查到的只有行 636 这一处与行 522 那一处对照。
⛔ 没量 run 4 与 run 1 那两次 pull_request 失败的原因,它们与本卡是否同因未知。
⛔ 没量定时触发本身是否每周都在放(total_count 只有 5 次运行、其中 schedule 仅 1 次)。本卡不主张调度器漏放,也不主张它没漏 —— 工作流 2026-09-07 才落,到 2026-09-14 只经过一个周一,与「每周一放一次」一致,但一个样本证不了周期性。
查重:按更新时间枚举 2026-09-06 以来的 2500 条(未穷尽),另对故障之后的窗口做了完整枚举 —— 卡号 18136..18340 每一个整数都在手(缺 0 个),shard-timings / RUN_COUNT / unbound variable 命中 0。

Refs:#16173(priority:p1 pm:on-hold,其 open_questions[0] 等的就是这条通道)· #16464(落了工作流,closed completed)· #16445(为此临时抬到 45 分钟的墙)· #16465(pm:blocked 的漂移告警)

- name: Push the refresh branch and open the pull request
  if: steps.compare.outputs.changed == 'true' && github.event_name != 'pull_request'

⇒ 卡面的读数一字未变:$RUN_COUNT 与 $RUNS 在 set -u 下仍是未绑定变量,写回步骤仍会在算完之后、推之前死掉。

⚠️ 本席对「数据集已 N 天未动」这个数的处理:本容器是浅检出(可见历史最早 2026-09-10 23:20),所以本席量不到卡面那个「自 2026-08-24 起 22 天」。本席能量到的是:在可见的这 13 天里,scripts/test-shard-timings.json 一次都没被改过,也没有任何一次标题为「refresh the Test Core shard-timings dataset」的提交落地。 ⇒ 方向与卡面一致,⛔ 但本席 ⛔ 不申报具体天数。

提级理由(p3 → p2)

当刻拉动是真的,而且在复利:分片按一个只会越来越旧的时长数据集切 ⇒ 越切越不均衡 ⇒ 总 CI 时长变长、尾部分片逼近 timeout-minutes。这不是静态缺陷,是每周都在恶化的那一类。
它是一条链的输入:ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465(分片预测 vs 实测漂移报警)与 ci: a per-package suite-duration ratchet — a PR that makes a suite exceed its measured ceiling is red; ceilings rise only by ruling (maintainer-directed, growth constraint) #16468(每包时长棘轮)都建在这个数据集上。数据集腐烂 ⇒ 预测失真 ⇒ 那两张卡装上去的报警报的是一个假基准。⇒ 三张同批取效果最好。
修复面极小:两行 env:。⭐ 而且发火对照就在同一文件里 —— 紧邻的「Compose the pull request body」步骤把同一批 outputs 四个全导出了(RUN_ID / RUNS / RUN_COUNT / HEAD_SHA)⇒ 值都存在、都可导,⛔ 不是 generator 少产。

⇒ 「代价在涨 + 修复两行 + 挡住另外两张卡的基准」三条合起来,p3 低了。

⚠️ ⛔ 不给 p1:今天没有任何 PR 被它挡住,红的是一个定时任务,不是任何人的合并路径。

⚠️ 取卡的人先读这一条

卡面自陈:本卡改 .github/workflows/** ⇒ 受管面,席位 auto_merge 恒 422,只能人工合(与 #18096 / #18224 同一堵墙)。⇒ 排期时把「等人合」算进去,⛔ 不要按自动合并估。

Draft PR #19933 (one file, .github/workflows/shard-timings-refresh.yml, +112/-39, head d4ba97991e) exports all four generate outputs. The commit message is unchanged: RUN_COUNT and RUNS stay in it. Structural defense: the event-gated write step and its mutually exclusive dry-run step are now ONE step with ONE env: and ONE script that runs on every event. On a pull_request run the branch, git add and commit run for real on the runner. Every act that leaves the runner (git push, gh pr create, gh pr view, label POST and read-back) goes through one outward() function switched by DRY_RUN, which is set from github.event_name == 'pull_request'. The script refuses a DRY_RUN other than true or false, refuses false on a pull_request run, and errors on an absent DRY_RUN. GH_TOKEN is read by gh and not by the shell, so it is named once as ${GH_TOKEN:?} and both legs judge it too. No new required check, gate, ratchet or job; lint.yml and cut-rc.yml untouched; no threshold touched (0 diff lines name MAX_SHARD_OVER_MEAN, MAX_MEASURED_OVER_PREDICTED, timeout-minutes or FILE_SHARDED_PACKAGES). workflow_dispatch was NOT triggered. The PR body names acceptance item 4 as owed after merge, with the command `gh workflow run shard-timings-refresh.yml --repo objectstack-ai/objectstack --ref main`. No changeset: the diff is .github/ only and publishes nothing, so it takes route 2 of Check Changeset. The seat must apply skip-changeset; the dispatch forbade labels, so none was written.

Scratch repo: a depth-1 clone of a local bare origin, with core.hooksPath=.githooks as the runner's pnpm install registers it (job log: 'git integration registered (... core.hooksPath)'). So the real pre-commit and pre-push hooks run. PATH shims sit in front of gh (records the call, answers canned values) and git push (records the call, forwards only to the local bare origin).

Seat read — PR #19933 at head `d4ba97991e4ccf756df587176238cdb724303e21`, and a correction to this seat's claim

domain:spec execution seat 1 (seat post #6017, session_013RDBh5DqXd2xnLwvHLgLFr), 2026-09-24T00:53Z.

Correction to claim 5804913750. Its 「Landing tier」 line says .github/workflows/** is a governed surface, so the merge is the maintainer's hand. That is wrong as a governed-surface reading. node scripts/pm/check-governed-merges.mjs --pr objectstack-ai/objectstack#19933, run from an origin/main snapshot, answers 「0 of 1 path(s) hit the register … ✅ NOT governed — ordinary queue landing applies」 and 「151 changed line(s) … under the human-merge threshold」. The card body's separate platform note, that seat auto_merge answers 422 on a .github/workflows/** PR (the #18096 / #18224 wall), is a platform reading, not a governance tier. The seat will try the ordinary landing once CI is green. If the platform refuses, the PR goes to the maintainer's hand, with the refusal quoted.

Review owed. The diff is one file, .github/workflows/shard-timings-refresh.yml. It touches none of the five review surfaces in references/contract-review.md ⇒ no at-tier contract review is owed; CI plus this seat's read decide.

This seat read the diff.

The write step's env: now exports RUN_ID, RUNS, RUN_COUNT and HEAD_SHA, plus DRY_RUN and GH_TOKEN. The commit message still expands $RUN_COUNT and $RUNS, unchanged.
The event-gated write/dry-run pair is now one step, with one env: and one script. Every outward act goes through one outward function, switched by DRY_RUN: ${{ github.event_name == 'pull_request' }}. The script refuses any other DRY_RUN spelling, and refuses anything but true on a pull_request run.
0 threshold lines changed.

Live reading. Actions run 35940088651 (Shard Timings Refresh, pull_request, head d4ba97991e) concluded success. Step 15, 「Push the refresh branch and open the pull request (dry run on pull_request)」, concluded success, so the write script ran before a merge for the first time. Step 16 was skipped.

Changeset. Workflow-only; it publishes nothing ⇒ skip-changeset, applied by this seat now.

Acceptance item 4 is still owed after the merge: one workflow_dispatch on main that opens a real refresh PR. The PR body names the command. The seat will put it to the maintainer at landing.

Landed — PR #19933 → `ec236d416c` on `origin/main`, verified by content

ccr/ready_for_review then PUT ccr/auto_merge (200, not the 422 the card body expected).
added_to_merge_queue at 2026-09-24T01:19Z, merged as squash ec236d416cb26daf0d49c7d5cf168d7b1648459d, parent fdeeea0cc9.

The criterion, re-measured on the write step's own env: block in .github/workflows/shard-timings-refresh.yml (the step 「Push the refresh branch and open the pull request」), parent against squash:

key in the write step's `env:`	parent `fdeeea0cc9`	squash `ec236d416c`
`RUNS`	absent	present
`RUN_COUNT`	absent	present
`DRY_RUN`	absent	present
`RUN_ID` (firing control)	present	present

The same step's run: expands $RUN_COUNT and $RUNS at both trees. The parent is the defect, and the squash carries the fix. The PR's own pull_request run 35940088651 executed this step's script, dry, before the merge (step 15, success).

Card state. pm:dispatched is removed and the assignee cleared in this act.

Still owed: acceptance item 4. One workflow_dispatch on main that opens a real refresh PR: gh workflow run shard-timings-refresh.yml --repo objectstack-ai/objectstack --ref main. This seat does not trigger workflows. It is put to the maintainer, and the result is the reading this card asked for.

ci: shard-timings-refresh 的写回步骤缺两个 env 变量,每周定时刷新在算完之后死于 `RUN_COUNT: unbound variable` —— 数据集已 22 天未动,而 pull_request 演练结构上跑不到这条腿 #18341

根因 —— 行 653 用了 `$RUN_COUNT` 与 `$RUNS`,行 638–641 的 `env:` 只给了两个

实测 —— 唯一一次定时运行的日志(run 34810389734,2026-09-14T05:38Z)

⭐ 为什么合入前的演练抓不到它 —— 推送路径结构上跑不到

影响 —— 一张 p1 卡正卡在这个通道上

验收(⛔ 不规定实现)

⛔ 没量的部分,不许当读数用

保留并提级 p3 → p2 —— 缺陷今天仍在 `origin/main` 上,本席逐行核过

⭐ 复核:缺陷没有自愈

提级理由(p3 → p2)

⚠️ 取卡的人先读这一条

状态

车道 `domain:devx` → `domain:spec` —— 补本席上一条漏掉的一步,否则这张 p2 没有人能取
