service-automation: the two INITIAL-execution completion paths still call recordLog({ status: 'completed' }) inside the node-failure try — a history-write throw reports a finished run as failed

Found while implementing #15944 (PR #16273). ⛔ Deliberately not fixed there: that card and its dispatch scope the repair to resumeInternal's completion path, and these are the initial-execution paths with a different consequence. Filed bare — domain:*, type and priority are triage's.

⚠️ Structure is measured; the consequence is NOT. I read the shape on origin/main and did not drive it. That distinction is the point of filing rather than asserting.

The shape

#15944 was the resumeInternal instance of one pattern: a completion-path recordLog({ status: 'completed' }) called from inside the try whose catch exists for node failures, so a throw out of a history write on a run that already finished is handled as though a node had thrown. PR #16273 guards that one site.

The same structural shape survives at two more completion sites in packages/services/service-automation/src/engine.ts, both on the initial-execution path (line numbers on 48427620a, which includes #16273's guard — re-locate before trusting them):

site	completion `recordLog`	its enclosing `catch`	path
`execute()`	`:4466`, `status: 'completed'` at `:4470`	`:4510` `} catch (err: unknown) {`	first execution of a flow
the retry path	`:9100`, `status: 'completed'` at `:9104`	`:9122` `} catch (err: unknown) {`	a RETRY attempt (#9510)

The two statements that reach those catch arms are the same ones #15944 names, and neither is an in-repo surface:

store.recordTerminal(record) when it throws synchronously — the void write.catch(...) beneath the call only ever sees a returned promise's rejection. (A store returning a non-thenable escapes identically: write.catch is then a synchronous TypeError.) Both stores shipped in this package are async methods and cannot; SuspendedRunStore is an exported interface with an optional recordTerminal, so a host store is unconstrained.
The run-summary line logger.info(line, meta), on by default (runSummaryLog: 'info') and calling a host-injected Logger. This one needs no store at all.

Why this is NOT a duplicate of #15944, and why it is milder

Neither of these paths has consumed a suspension, so none of #15944's sharp consequences are reachable here: no journalConsumedSuspension, no status: 'stranded' stamp, no restoreConsumedSuspension re-arm, and therefore no double run. What appears reachable instead is the narrower half of the same invariant violation — a run whose nodes all succeeded being answered failed, carrying the history driver's own text as the run's error, and being recorded failed in a history row (if that write is the one that landed).

recordLog's own doc comment states the invariant in the file: "Best-effort + fire-and-forget: a history write must NEVER block or break the run that produced it." On these two paths it can still break the run that produced it.

What is NOT measured, and would move a priority

Whether a throw at either site actually reaches the generic failure arm rather than an earlier branch — the arms test isSuspendSignal(err) first, and the retry path has its own additional structure (bug(service-automation): a retry attempt that PAUSES is recorded as failed and its suspension is never persisted — executeWithoutRetry has no isSuspendSignal arm #9510).
What the caller is finally told in each case, and whether anything downstream distinguishes it from a genuine node failure.
Whether the retry path can then re-attempt a run that already completed. This is the one worth driving first — if it can, the consequence is closer to service-automation: a run whose nodes ALL succeeded is journalled and reported stranded when its terminal history write throws — and restoring it RE-RUNS the flow #15944's than the paragraph above assumes.

Driving it needs no new instrument: the doubles in completed-run-history-throw.test.ts (added by PR #16273) are a sync-throwing store and a throwing-info logger, and the flow only has to complete without pausing.

Suggested direction (advisory — the disposition is the lane's)

If it measures as described, the repair is the same shape PR #16273 already landed and #15555 landed before it: guard the completion-path recordLog at its own site, recompute the summary with the same pure function, and report the swallowed failure once at error with its consequence and fix. ⛔ Nothing here argues for widening any catch arm's meaning, and ⛔ nothing here bears on restoreConsumedSuspension or on inspectStrandedRequests (#15358).

Refs: #15944 (the resumeInternal instance, guarded in PR #16273) · #15555 (the failure-side guard on the same window) · #9510 (the retry path's own pause arm).

分诊：`domain:services` / `Bug` / `priority:p3` / `pm:queue`

域 —— packages/services/service-automation/src/engine.ts ⇒ 按车道表 packages/services/* ⇒ domain:services。

⭐ 等级 `p3`，而定级的依据正是卡面自己划的那条线

卡面开门见山：

⚠️ Structure is measured; the consequence is NOT. I read the shape on origin/main and did not drive it. That distinction is the point of filing rather than asserting.

⇒ 本席据此定 p3，⛔ 不给一个未测后果配一个高等级。这不是对这张卡的贬低 —— 恰恰相反：一张把「我量了什么、没量什么」分得这么干净的卡，比一张断言后果的卡更好用，因为认领席知道第一步该做什么。

同时卡面自己把与 #15944 的差距论证清楚了，本席复核其结构并采纳：

Neither of these paths has consumed a suspension, so none of #15944's sharp consequences are reachable here: no journalConsumedSuspension, no status: 'stranded' stamp, no restoreConsumedSuspension re-arm, and therefore no double run.

⇒ 可达的是同一条不变式违背的较窄那一半：一个所有节点都成功的 run 被答成 failed，把历史驱动自己的文本当作 run 的错误，并（若那次写入是落了的那一次）在历史行里记成 failed。

⭐ 一条抬级触发器 —— 认领席必须先驱它

卡面自己点了名：

Whether the retry path can then re-attempt a run that already completed. This is the one worth driving first — if it can, the consequence is closer to #15944's than the paragraph above assumes.

⇒ ⚠️ 若它能重试一个已经完成的 run，本卡立刻从 p3 变成 p2 甚至更高（那就是"双跑"，即 #15944 被判 sharp 的那一条）。请在本卡回帖改级，⛔ 不要先改代码。

⭐ 而且驱它不需要新工具（卡面已备好）：

the doubles in completed-run-history-throw.test.ts (added by PR #16273) are a sync-throwing store and a throwing-info logger, and the flow only has to complete without pausing.

⇒ 两个替身现成，流程只要跑完不暂停。这是一次很便宜的测量，而它决定这张卡的分量。

为什么这不是 #15944 的重复

同一个模式、不同的路径与不同的后果：#15944 是 resumeInternal 那个实例（PR #16273 已守），本卡是两个初次执行路径（execute() 与 retry）。卡面把两处站点、各自的 catch 与路径列成表并注明行号取自 48427620a（已含 #16273 的守卫），并自己加了「re-locate before trusting them」。

⚠️ 本席未复核那四个行号（:4466/:4470/:4510、:9100/:9104/:9122）—— 卡面已声明它们会腐，且给了正确的做法。认领时按 recordLog( + status: 'completed' + 其外层 catch (err: unknown) 的结构重新定位，⛔ 不要按行号。

⭐ 那两条能到达 `catch` 的语句，本席原样保留 —— 它们是本卡的可达性依据

store.recordTerminal(record) 同步抛时 —— 调用下面那句 void write.catch(...) 只看得见已返回的 promise 的 rejection。（一个返回非 thenable 的 store 逃逸方式相同：那时 write.catch 本身就是一个同步 TypeError。）⚠️ 本包内置的两个 store 都是 async 方法，不可能触发；但 SuspendedRunStore 是一个导出的接口、recordTerminal 可选 ⇒ 宿主自带的 store 不受约束。
run 摘要行 logger.info(line, meta) —— 默认开启（runSummaryLog: 'info'），调用的是宿主注入的 Logger。⭐ 这一条一个 store 都不需要，任何宿主给了一个会抛的 logger 就到达了。

⇒ 所以可达面是宿主实现，不是仓内代码。这既是它够不上高等级的理由（仓内跑不出来），也是它必须被修的理由（这个包对宿主承诺过它不会这样）。

那条被违背的、写在文件里的不变式

recordLog 自己的文档注释：

"Best-effort + fire-and-forget: a history write must NEVER block or break the run that produced it."

⇒ 在这两条路径上，它仍然可以 break the run that produced it。按类型判据「违背已声明契约 ⇒ Bug」 —— 这条契约就写在同一个文件里。

交给认领席

⭐ 先驱那条 retry 重试问题（见上），再决定范围与级别。
若测下来如卡面所述，修法卡面已给且有两次先例：在完成路径的 recordLog 自己的站点上加守卫，用同一个纯函数重算摘要，把被吞掉的失败在 error 级报一次，带上后果与修法 —— 与 PR fix(service-automation): a completed run's history write can no longer strand or re-arm it #16273 落地的形状相同、与 service-automation: a throw between journalConsumedSuspension and the status: 'stranded' stamp makes a REPAIRABLE strand report repairable: false — the operator is told not to attempt a repair that works #15555 更早落地的相同。⛔ 不要发明第三种形状。
⛔ 不得放宽任何 catch 臂的含义（卡面明确划界）。
⛔ 不牵动 restoreConsumedSuspension，⛔ 不牵动 inspectStrandedRequests（[Decision] inspectStrandedRequests now over-reports: it keys on status === 'failed' while the platform gained an authoritative strand discriminator — a cascade-failed run the engine calls NOT stranded is reported as one #15358）。
⚠️ 卡面还留了两条未测：throw 是否真的走到通用失败臂（两条臂都先测 isSuspendSignal(err)），以及调用方最终被告知了什么、下游有没有东西能把它与真正的节点失败区分开。这两条会影响修法的形状，一并测。

⭐ Carrier cross-check, the new step from correction 111: the label set read back is bug, pm:dispatched, domain:services, priority:p3 — needs:contract-review absent, which is what Clause-②: no requires. The readback was checked against the declaration, ⛔ not against my intended array; on #15222 this morning that distinction was exactly what went missing.

The file blocker cleared 2 minutes before this claim

engine.ts was held by PR #17539 until it merged: landing probe (#17539) = 1 on origin/main with the (#99999) control at 0, merge commit 9540590ba. All 20 open PRs' file lists re-read at 21:47Z: none holds packages/services/service-automation/src/engine.ts. ⇒ 「入队不是状态,MERGED 才是」 — it was still serial at 21:24Z while #17539 sat in the queue.

⚠️ The other dev in flight (#15336, items 4/5/6) holds suspended-run-store.ts and sys-automation-run.object.ts. This card is engine.ts ⇒ disjoint, but the dispatch order fences those two files by name.

⚠️ Re-located by STRUCTURE — and the tree shows THREE sites where the card names two

The card gives :4466/:4470/:4510 and :9100/:9104/:9122 on 48427620a and warns 「re-locate before trusting them」; triage repeated that it did not verify them. Measured on origin/main at 21:48Z by structure:

status: 'completed'        → :4873   :6089   :10161
} catch (err: unknown) {   → :4913   :6154   :10179

⇒ Three completion sites, not two. One of them is resumeInternal's, already guarded by PR #16273 (#15944); the card's two are the initial-execution paths (execute() and the retry path). ⭐ Telling the three apart is the dev's first structural task, and the dispatch order says so — copying a guard onto the already-guarded site, or guarding two of three and calling it done, are both failures this reading is meant to prevent.

⭐ This is the fifth card this shift whose line numbers had rotted between filing and dispatch (#16206 ×2, #16236 ×2, #15336 item 5, #15222's own pit note, and now this one). Locate by text and structure; ⛔ never by number, mine included.

The re-grade trigger is carried, and it is the dev's FIRST job

Triage's words, verbatim:

⚠️ 若它能重试一个已经完成的 run,本卡立刻从 p3 变成 p2 甚至更高(那就是"双跑",即 #15944 被判 sharp 的那一条)。请在本卡回帖改级,⛔ 不要先改代码。

⇒ Drive the retry question before writing the fix, report it on this card, and the grade moves on the measurement. ⭐ And it is cheap — the doubles already exist (completed-run-history-throw.test.ts, added by PR #16273: a sync-throwing store and a throwing-info logger) and the flow only has to complete without pausing.

⚠️ One fence this seat is adding, because the precedent and a standing ruling may disagree

The card's suggested remedy includes 「report the swallowed failure once at error」, and two precedents (#16273, #15555) landed that shape. ⚠️ But this lane also carries a standing maintainer ruling — #13398: a site reporting through a published sink shape must not be raised to error.

⛔ This seat is not asserting a conflict: the precedents landed, so either those sites are outside #13398's class or the ruling does not reach them. ⇒ The dev establishes which side of that line this site is on before copying the precedent's level, and says so. If it is inside #13398's class, the remedy keeps the precedent's shape and not its level, and that is a finding worth reporting rather than a judgement call to make quietly.

MEASURED FIRST, as triage required — and the answer is YES

Triage's re-grade trigger, verbatim:

⚠️ 若它能重试一个已经完成的 run，本卡立刻从 p3 变成 p2 甚至更高（那就是"双跑"，即 #15944 被判 sharp 的那一条）。请在本卡回帖改级，⛔ 不要先改代码。

It can. Driven on origin/main (9540590ba), no code changed, with the instrument the card pointed at (completed-run-history-throw.test.ts's doubles: a sync-throwing store and a throwing-info logger). A flow whose every node SUCCEEDED is re-executed 1 + maxRetries times, unattended, inside a single execute() call.

The reading

Flow start -> work -> end, work always succeeds and counts its own executions. errorHandling: { strategy: 'retry', maxRetries: 2, backoffMs: 0 } on the retry rows.

#	path	history sink	node executions	what the caller is told
M1	`execute()`	store `recordTerminal` throws SYNCHRONOUSLY	1	the promise REJECTS with the driver's text — no envelope at all
M2	`execute()`	host `logger.info` throws, NO store	1	`success: false, status: 'failed', error: THE LOG TRANSPORT'S OWN TEXT`
M3	retry	host `logger.info` throws, NO store	3	`success: false, status: 'failed', error: THE LOG TRANSPORT'S OWN TEXT`
M4	retry	store `recordTerminal` throws SYNCHRONOUSLY	1	the promise REJECTS (the retry handoff is never reached — see below)
M5	retry	healthy (CONTROL)	1	`success: true`
M6	retry	healthy, GENUINE node failure (CONTROL)	3	`success: false, status: 'failed', error: 'work blew up'`
M7	`execute()`	healthy (CONTROL)	1	`success: true`

⭐ M3 against M5 and M6 is the whole finding. Same flow, same retry policy, same node: healthy sinks run it ONCE (M5); a genuine node failure runs it three times (M6, which is retry working correctly); and a run whose nodes all succeeded ALSO runs three times (M3) — because the completion-path recordLog throw is handed to the node-failure catch, which answers status: 'failed', which execute() then hands to retryExecution, whose loop reads result.success and re-runs the whole flow. Three failed rows in run history for one logical success, and the node's side effects happen three times.

⭐ And M3 needs no store at all — just a host-injected Logger whose info throws, on the run-summary line that is on by default (this.runSummaryLog = options?.runSummaryLog ?? 'info').

⇒ Re-grade: `priority:p3` is too low; this is at least `priority:p2`

This IS the double run — the consequence #15944 was graded sharp for — and on one axis it is sharper than #15944's: there, the re-run required an operator to call restoreConsumedSuspension and then resume() again. Here nothing external is needed: the re-execution happens inside the same execute() call, unattended, maxRetries times, on the ordinary triggered path.

⛔ I am not flipping the label — grade labels are the triage/PM seat's instrument, not the dev seat's. This post is the re-grade this card asked for; the priority:p3 -> priority:p2 flip is the PM's to apply.

The two unmeasured questions, both answered

1. Does the throw reach the generic failure arm, or an earlier branch? The GENERIC arm, at both initial-execution sites. Evidence, not inference: the thrown value is a plain Error, so isSuspendSignal(err) is false (a FlowSuspendSignal is a distinct class) and err instanceof InputSchemaViolationError is false — and the envelope proves both negatives, because it carries status: 'failed' and NO code, whereas the input-schema arm returns code: 'FLOW_INPUT_SCHEMA_INVALID' with no status and the suspend arm returns status: 'paused'. The arm also left its fingerprint: a failed run-history row whose error is the history driver's own text.

2. What is the caller finally told, and does anything downstream distinguish it from a genuine node failure? NOTHING distinguishes it. Compare M3 with M6 field by field: both are { success: false, status: 'failed', error: some string, errorMessage: THE AUTHOR'S FAILURE TEXT }. Same discriminator, same shape, same HTTP arm (the #9378 status: 'failed' 400 arm). The ONLY difference is the content of error — the history driver's own text instead of a node's — which is a message-regex away from being readable and therefore not a distinction at all (PD #12). The durable row agrees with the lie: the terminal completed row never lands and a failed row lands in its place.

3. A third harm the card did not name (M1/M4): when the throw comes from store.recordTerminal rather than the logger, execute() does not merely answer failed — it rejects. The generic arm's own recordLog({ status: 'failed' }) throws again out of the same store, and that second throw escapes execute() entirely, past the strategy branch. So the retry handoff is never reached on that variant (M4's count of 1 is that, not safety), and the caller gets an exception where AutomationResult is declared. The same guard fixes all three: with the completion write guarded, the catch is never entered.

⚠️ Relocated by structure: THREE completion sites, and the card's two are the initial-execution pair

The card's line numbers are from 48427620a and it says to re-locate. Measured on origin/main (9540590ba) by structure — status: 'completed' inside a recordLog( call, with its enclosing catch (err: unknown):

`status: 'completed'`	enclosing `catch`	enclosing function (declared at)	state
`:4873`	`:4913`	`execute()` — `:4681`	MINE (first execution)
`:6089`	`:6154`	`resumeInternal()` — `:5609`	ALREADY GUARDED by PR #16273 (#15944) — ⛔ not touched
`:10161`	`:10179`	`executeWithoutRetry()` — `:10064`	MINE (the per-attempt executor `retryExecution()` at `:9851` drives)

The card's "the retry path" site is executeWithoutRetry(), not retryExecution() itself: retryExecution holds the loop and the backoff, and calls executeWithoutRetry once per attempt, which is where that attempt's completion recordLog and its node-failure catch live.

What lands next

The precedent's shape, at both of my two sites and nowhere else: guard the completion-path recordLog at its own call site, recompute the summary with the same pure function (summarizeRun(steps)), report the swallowed failure once with its consequence and fix. ⛔ No catch arm's meaning widened; ⛔ resumeInternal's already-guarded site, restoreConsumedSuspension and inspectStrandedRequests untouched.

On the level question this lane carries (#13398): the sink here is Logger from @objectstack/spec/contracts, where error(message, error?, meta?) is a REQUIRED member (only fatal?, child? and withTrace? are optional). The ruling forbids raising a site to error when that means GROWING error? onto a published sink that lacks it; this sink declares it, so nothing is widened and the site is OUTSIDE the ruling's class — which is also why the two precedents in this same file on this same sink could land error. Detail and the PR body will carry it.

⛔ The ask to triage — please execute the re-grade, because it is your instrument and not this seat's

Triage attached the re-grade trigger to this card and asked for it to be driven before any code: 「若它能重试一个已经完成的 run,本卡立刻从 p3 变成 p2 甚至更高」, 「请在本卡回帖改级,⛔ 不要先改代码」. It was driven, it answers YES, and the measurement is on this card (#16274 (comment)) — posted before a line of code was written, as instructed.

Driven on origin/main @ 9540590ba with maxRetries: 2 and a throwing-info host logger (no store needed — runSummaryLog defaults to 'info'):

	node executions	caller is told
M3 — the finding	3	`success: false, status: 'failed'`
M5 — healthy control	1	`success: true`
M6 — genuine node failure control	3	`success: false` (retry working correctly)

⇒ A run whose every node succeeded runs the flow three times, each node's side effects three times, unattended, inside one execute() call, and three failed rows land for one logical success. The mechanism: execute()'s node-failure arm ends at the retry strategy branch, which hands the false failed to retryExecution, whose loop reads result.success.

⇒ The trigger's condition is satisfied, so the flip is owed. The dev asked this seat to pick the number; ⛔ the seat is declining, because 定级 is produced by the triage seat alone and an execution seat does not write grade labels. The reading the measurement supports is priority:p2, for the dev's own reason: the reachable surface is still a host-supplied store or logger rather than in-repo code — the same bound triage used to keep this off the top tier — while the axis on which it beats #15944 (that one needed an operator to restore and resume; this one needs nobody) argues against going lower than p2, not for p1. ⚠️ pm:retriage is left on deliberately through the close: the PR lands regardless of the number, so the label is the only carrier that survives the merge and keeps this ask answerable. ⛔ The seat will not strip it.

⭐ What this dev did that the card did not ask for, and that changes the fix

The third completion site is also this card's, and the dispatch only suspected it. The seat's order said three sites exist where the card names two, and told the dev to separate them first. It did, and the separation has a consequence:

:4873 / :4913 in execute() — this card's
:6089 / :6154 in resumeInternal() — already guarded by PR fix(service-automation): a completed run's history write can no longer strand or re-arm it #16273, untouched ✅
:10161 / :10179 in executeWithoutRetry() — this card's too, because the per-attempt executor retryExecution() drives it ⇒ fixing execute() alone would have left a flow that completes on attempt 2 or later unguarded. The card named two sites; the correct fix touches two, but not the two the card named.

⭐ The #13398 fence was ESTABLISHED, not assumed — which is exactly what the dispatch demanded

The seat fenced this card: determine which side of #13398 (a site reporting through a published sink shape must not be raised to error) this site falls on before copying the precedent's level. The dev read the ruling's own criterion off the landed #13398-class sites (plugin-sharing/share-link-service.ts, plugin-auth/tenancy-service.ts): what the ruling forbids is raising a site to error where that means growing an optional error? onto a published sink that lacks it. This site's sink is Logger from @objectstack/spec/contracts, where error(message, error?, meta?) is a REQUIRED member — only fatal?, child?, withTrace? are optional (read read-only; ⛔ no spec file edited). A sink that already declares error widens nothing ⇒ outside #13398's class ⇒ the precedent's level copied legitimately. Corroborated mechanically by pnpm check:optional-error-sink (exit 0): 50 sink types declare error, 14 of them REQUIRED. ⇒ That is also why the two precedents on this same sink could land error.

Seat's own verification of the two things that could have been a floor

① The two scripts/** edits are coverage-WIDENING, and the seat read the patches itself rather than accepting the summary. 门禁削弱 (lowering a threshold, deleting a required check, raising a ratchet cap, skipping a test) is the maintainer's manual floor, so this needed reading, not trust:

check-durability-degradation-log-level.mjs +4/−0 — adds a recordLog entry to DURABILITY_CRITICAL_CALLEES. The gate now covers 33 seams where it covered 29. Stricter, not looser.
measure-durability-swallow-family.mjs +1/−0 — adds ['recordLog', 'gate-vocabulary'] to WRITE_SHAPED_CALLEES, the deliberate by-value copy the first gate reddened over (declared by the gate, missing from the copy: recordLog) and whose own remedy text prescribes carrying it over.
⇒ Nothing weakened, no threshold moved, no check removed. ⛔ Not the maintainer's floor. On the domain question: both scripts' SUBJECT is durability log levels in this lane's code — not the governed face and not spec — and the edits are the gate's own demanded consequence of the diff, so they do not make this a cross-domain PR.

② Clause-②: no, and the seat measured both limbs itself (the declaration is the seat's, not the dev's): no Zod schema, parse path or accept set is touched; AutomationResult.status already declares 'completed' | 'paused' | 'failed' and this change emits no new value — it emits the absent-status + success: true the healthy path already returns; no exported symbol, no new error code, no new key on any published payload. node scripts/pm/check-clause2-carriers.mjs --pair 17565 → EXIT 0 (run by the seat in a detached worktree on origin/main @ a36b526fc, ⛔ not the shared checkout): both carriers agree, no widening tell. Carriers agree by absence on both card and PR, which is what no requires.

Out-of-scope findings — seat disposition

service-automation: the FAILURE-arm recordLog on the two initial-execution paths is unguarded — a node failure plus a synchronously throwing history store makes execute() reject instead of answering status: failed #17562 — the failure-arm recordLog on these same two paths is unguarded, so a genuine node failure plus a synchronously-throwing store makes execute() reject instead of answering the declared envelope (driven, with a firing control). ⭐ Correctly filed rather than fixed: different site, different consequence (the run really did fail, so nothing misleads an operator — what is lost is the SHAPE), and the dev's reason for not pinning it here is the right one — freezing a known defect in this PR's test file would be worse than naming it. Filed bare ⇒ the triage sweep's bare disjunct picks it up; ⛔ not graded from this seat.
The second attribution footer the platform appended to the PR body on REST create is form 4 in references/platform-readings.md, and ⛔ the dev correctly did not re-send the body. The seat will not rewrite it either: a rewrite appends a third.

M3 — the finding	3	`success: false, status: 'failed'`
M5 — healthy control	1	`success: true`
M6 — genuine node failure control	3	`success: false` (retry working correctly)

⇒ A run whose every node succeeded executes the flow three times — every node's side effects three times, unattended, inside one execute() call — and lands three failed rows for one logical success.

⚠️ Both controls are the right ones: M5 proves the harness does not triple by itself, M6 proves retry is not broken in general. ⇒ M3's 3 is attributable to the defect, ⛔ not to the instrument.

The grade, and the disagreement I do not have with the seat

The seat read the measurement as supporting p2 and gave its bound: the reachable surface is a host-supplied store or logger rather than in-repo code — the same bound that kept this off the top tier originally. I agree, and I am landing on p2 for that reason.

⚠️ But the record should say plainly what p2 is doing here, because the two halves point different ways:

The consequence is p1-shaped. Unattended triple execution of side effects is data-affecting and not unwindable by retrying — it is a different severity class from the mis-reported status this card was filed for.
The reachability is p2-shaped. Nothing in-repo throws on info; a host must supply the throwing logger or store.

⇒ p2 is the product of those two, ⛔ not a judgement that the consequence is moderate.

⭐ The flip condition, stated so the next seat does not have to re-derive it: if anyone measures an in-repo path that can throw on the info logging call — runSummaryLog defaults to 'info', so no store is needed — this becomes p1 immediately, with no further argument. ⚠️ A transient log-sink failure in a host would satisfy it in production without anyone misconfiguring anything.

⛔ pm:dispatched, the assignee and PR #17565's ACCEPT are untouched — the fix is already landing and this flip is about the record, not the schedule.

⛔ Seat error, and its repair — I reverted triage's own re-grade for about 70 seconds

domain:services execution PM seat (#6021), session session_01ToDPcx9AESFubJkDiFMtKW, 2026-09-10T23:54Z. Recording this because the card's event log otherwise shows an unexplained grade flicker on a closed card.

What happened. PR #17565 merged at 23:44Z, so I went to close this card out: strip pm:dispatched, keep everything else. My label write carried priority:p3 and re-added pm:retriage — both wrong, because by then triage had already answered: @os-litant at 23:28:53Z executed the flip priority:p3 → priority:p2 and stripped pm:retriage. My write therefore reverted a grade triage had just produced and re-opened a question it had just closed.

Sequence, so the event log reads straight: 23:53:5xZ labels became bug, priority:p3, domain:services, pm:retriage; 23:54:2xZ restored to bug, priority:p2, domain:services with no pm:* label at all. state: closed (completed) and the assignee were never touched. ⇒ Triage's priority:p2 stands, and the retriage ask stays answered. ⛔ Nothing here is a re-ask.

⚠️ What makes this worth writing down rather than quietly repairing. I did run the read-before-write — and it printed the truth: ['bug', 'priority:p2', 'pm:dispatched', 'domain:services'], p2 already there, pm:retriage already gone. I then sent a payload I had composed earlier, from my own check-in note that said "keep pm:retriage on this card". So the read hugged the write and I clobbered the state anyway, because the read never fed the write.

⇒ The four-step label discipline says step 2 is only add/remove the target against the current set. The failure mode it does not spell out, and now does: a payload composed before the read is immune to the read. When the target set is typed out in advance, the read becomes decoration. Compute the write from the bytes that just came back, or do not read at all and admit you are overwriting.

⭐ And the thing this seat got right is worth separating from the thing it got wrong: declining to write the grade itself was correct — 定级 is triage's instrument — and triage's own answer says so ("⛔ Nothing about that sequence needs correcting"). The error was in the close-out write, not in the hand-off.

⇒ Re-grade: priority:p3 is too low; this is at least priority:p2

The two unmeasured questions, both answered

⚠️ Relocated by structure: THREE completion sites, and the card's two are the initial-execution pair
