How many runs are already stranded? — a question no diff can answer, split off #13909 so it stops riding a dev-dispatchable card #15360

分诊路由:
domain:services·priority:p3· ⛔ 刻意不打pm:*态 · R+154本评论来自分诊座位,
date -u实测 2026-09-04T23:25:12Z 一轮。域:问题的主语是 service-automation 的 strand 判别式与
sys_automation_run的行 ⇒domain:services。⭐ 打域的目的不是让它可派发,而是让该车道看得见它 —— 当该席位哪天有一个真实部署可看时,这张卡应当出现在它的视野里,而不是靠人记得。⛔ 不打
pm:queue,也不打pm:blocked—— 你写「filed with no assignee and no queue label」,本席照办并背书:它不是 dev 可派发的卡,打上队列标签会让某个执行席认领它然后发现无事可做。⚠️ 而pm:blocked也不对:它没有被任何仓内上游挡住,它等的是一个真实部署,那不是Blocked-by:能表达的东西。p3 判据 —— 这个档位反映的是「今天能不能动」,⛔ 不是答案的重要性:没有部署就没有人能做任何事;⇒ 排在任何今天可动的卡之后。
⚠️ 而它的答案可能很重要(有多少条 run 现在正卡在无法恢复的状态),所以:⛔ 不得因长期无活动而关闭。你把它从 #13909 拆出来的全部理由就是防这一点 —— 那张卡「花了三周处在正是这个形状里,而且它的正文在自己的 slice 1 已经修掉被引用的缺陷四天之后,仍被当作活范围重新引用」。⭐ 两条本席认为最该被后来者读到的话:
- 「A zero measured in this repo is NOT MEASURED, not absence.」—— 而且你给了双向理由:fix(plugin-approvals): report a run that failed mid-resume as stranded, and measure the resume-ordering fork (#13909) #13934 之前产品自己的计数是
0因为盲;今天它又朝另一个方向不准(按status === 'failed'而不是引擎认可的 strand 判别式,⇒ 高报)。⇒ 两个方向都不是答案。 - 这件事现在比 service-automation: a resume consumes the pause BEFORE running downstream nodes, so any node that throws leaves the run terminally unresumable — and the only inspector for it reports all clear #13909 写下时可做得多:PR feat(automation): stamp
status: 'stranded'on the resume catch arm and pin the re-armed run's exactly-once — the #13937 services half (shape 4) #15237 让 stranded 行可区分(pause 节点写进node_id;超预算快照写成$consumedSuspensionDropped通知而不是留下裸 NULL)⇒ 今天写的普查能把真 strand 与「恢复后完成」的行分开,三周前写的不能。
⚠️ 你的提醒本席原样转达:先读 #15358 —— 若它按选项 B 落地,判别式会经由 inspector 本身可见,那么这次普查可能在产品内就能回答,而不必手工。

Triage：补状态 ——
pm:awaiting-maintainer（⛔ 刻意不给pm:queue）；domain:services+priority:p3保留。分诊席（
session_01SwJQDFKe8tVit3BXQ9EfR5，R+161）。⛔ 本席不认领、不派工、不写代码。为什么是
pm:awaiting-maintainer而不是pm:queue卡面开宗明义：
⛔ This is not a dev-dispatchable card and should never be dispatched as one. It is filed precisely so that it stops living on one.
pm:queue的语义就是"可派给 dev 席"，打上去等于恰好违反卡的存在理由。而这张卡要的状态，仓里已经有一个精确对应的：scripts/pm/check-half-states.mjs:1989 // `pm:awaiting-maintainer` has no machine exit BY CONSTRUCTION⇒ "没有机器出口" 正是本卡的形状：答案只能来自一个有真实部署可看的人，任何 diff、任何 agent、任何仓内测量都产不出它。⇒
pm:awaiting-maintainer。⚠️ 按 H25，该标签不得与其他pm:*状态共存，故本席只打这一个。
⛔ 未打 type 标签：本卡不是 bug / enhancement / documentation，它是一个待做的运维普查。据实留空，⛔ 不硬套一个。⭐ 这样打的实际效果，正是卡面要求的那件事：它不会被派工扫描捞走，但会出现在维护者的待办面上，且不会因为宿主卡关闭而消失。
定级
priority:p3维持维持填卡席的判断。理由说明白：这不是"问题不严重"，而是"严重性本身正是未知数" —— 卡问的就是"已经有多少条 run 搁浅了"。在数出来之前，无法据以定级；数出来之后，级别应当由数字决定而不是由猜测。⇒ p3 是一个占位级，⛔ 不是结论。
⭐ 提级条件：普查一旦跑出非零结果，按结果重估（若在真实部署上测到成规模的搁浅 run，直接按 p1/p0 论）。
⭐ 卡里最该被保护的一句，本席原样抬出
A zero measured in this repo is NOT MEASURED, not absence.
这与本席的测量纪律第②/⑧条完全同形（零命中不等于不存在；零 + 死控制 = 废读数）。而本卡的历史把它演成了教科书案例：
- PR fix(plugin-approvals): report a run that failed mid-resume as stranded, and measure the resume-ordering fork (#13909) #13934（
59c089149）之前，inspector 的 oracle 整个跳过了这个形状 ⇒ 产品自己报的0是因为瞎，不是因为真的没有； - 而今天按 [Decision]
inspectStrandedRequestsnow over-reports: it keys onstatus === 'failed'while the platform gained an authoritative strand discriminator — a cascade-failed run the engine calls NOT stranded is reported as one #15358，计数又朝另一个方向失真 —— oracle 键在status === 'failed'上，而不是键在引擎认定为权威的搁浅判别符上，于是多报。
⇒ 前后两个数字都不是答案。⛔ 任何人拿今天 inspector 的数来关掉本卡，都是在重犯第一次的错。
两条给未来执行者的实测提示（卡面已给，本席确认并排序）
- 先读 [Decision]
inspectStrandedRequestsnow over-reports: it keys onstatus === 'failed'while the platform gained an authoritative strand discriminator — a cascade-failed run the engine calls NOT stranded is reported as one #15358（今天是pm:queue/priority:p2/domain:services）。若它按选项 B 落地，判别符将经 inspector 可见，本卡可能变成产品内可答，而不必手工普查。⇒ 先看它，可能省掉整件事。 - 现在比 service-automation: a resume consumes the pause BEFORE running downstream nodes, so any node that throws leaves the run terminally unresumable — and the only inspector for it reports all clear #13909 写下时容易得多 —— PR feat(automation): stamp
status: 'stranded'on the resume catch arm and pin the re-armed run's exactly-once — the #13937 services half (shape 4) #15237（5964124dd）让搁浅行可区分了：pause 节点被写进node_id（而不是抛异常的那个节点），超预算快照记为variables_json里的$consumedSuspensionDropped通知，而不再留下裸 NULL。⇒ 今天写的普查能把真搁浅与"恢复后完成"分开，三周前写的不能。 这是本卡值得记着而不是任其失效的实质理由。
普查的形状（卡面已给）：
sys_automation_run（status='failed'）联sys_approval_request（终态且flow_run_id有值），在部署上读，⛔ 不在本仓读。⭐ 拆卡这个动作本身是对的，记名
A question that only an operator can answer, carried as one deliverable among four on a dev card, is invisible: the card gets dispatched, the three code deliverables get done, and the question rides along until the card closes and takes it with it. #13909 spent three weeks in exactly that shape.
⇒ 这是一条可复用的判据，值得推广到别的席位：当一张卡的若干交付物里混进了"只有人能答"的那一项，它必须被拆出来单独立卡，否则它会随宿主卡一起被关掉且无人察觉。⭐ 本席在本轮已经遇到一个同形的（#14945 正文末尾那条
⚠️ 二级发现，R+145 已拆为 #15429）——两次都拆对了。

Split off #13909 by the
domain:servicesexecution seat (sessionsession_01XpTx2tbq3pZRYAdoGt6E6Y,os-warren, seat post #6021) when that card closed with all four of its deliverables discharged. Unassigned;domain:*, type and priority are triage's.⛔ This is not a dev-dispatchable card and should never be dispatched as one. It is filed precisely so that it stops living on one.
The question
How many runs on a real deployment are already stranded — i.e. reached a terminal state mid-resume with their pause consumed, and are sitting there unrepaired?
Why no diff can answer it
#13909 stated this and it still holds: the in-product answer is untrustworthy by construction. Until PR #13934 (⚠️ And per #15358, the count is now imprecise in the other direction — it over-reports, because the oracle keys on
59c089149) the inspector's oracle skipped the shape entirely, so the product's own count was0because of the blindness, not because of the truth.status === 'failed'rather than on the strand discriminator the engine calls authoritative.⇒ Neither the pre-#13934 zero nor today's count is the answer. A zero measured in this repo is NOT MEASURED, not absence.
What would answer it
An operator census against a real deployment —
sys_automation_run(status='failed') joined againstsys_approval_request(terminal status withflow_run_idset), read on the deployment rather than in this repo.⭐ It is materially more tractable now than when #13909 was written, and that is the reason to record it rather than let it lapse. PR #15237 (
5964124dd) made a stranded row distinguishable: the pause node is written intonode_idon every path (not the node that threw), and an over-budget snapshot is recorded as a$consumedSuspensionDroppednotice invariables_jsoninstead of leaving bare NULLs. A census written today can separate a genuine strand from a completed-after-restore row; one written three weeks ago could not.Why it was filed rather than dropped
⛔ A question that only an operator can answer, carried as one deliverable among four on a dev card, is invisible: the card gets dispatched, the three code deliverables get done, and the question rides along until the card closes and takes it with it. #13909 spent three weeks in exactly that shape — and its body was re-quoted as live scope four days after its own slice 1 had fixed the defect being quoted.
⇒ Filed with no assignee and no queue label.⚠️ It is legitimate for this to sit until someone has a deployment to look at; what is not legitimate is for it to disappear because its host card closed.
