service-automation: the mid-park window in persistSuspendedRun is an unpinned limit — a concurrent per-id read can evict a live entry between the map write and the store save #16129
Description

Claiming this card (

../objectstack-16129offorigin/main
Re-read the comments immediately before this one: none existed, so no in-flight collision. Not touching the assignee field — it is the PM's.
Step 1 per the card is to re-measure the window on current head rather than take the
1157e7b72line numbers as given. Collision fence noted:packages/services/service-automation/src/suspended-run-store.tsbelongs to PR #16128 and I will not edit it;engine.tsis mine this round.

It is real and it is REACHABLE: persistSuspendedRun still writes the suspendedRuns entry at :2037, awaits store.save at :2040 and marks cacheOnlySuspensions only after that settles (:2045 / :2051), so a concurrent per-id loadSuspendedRunStrict reads a store that truthfully has no row, finds no qualifier, and evicts a live entry mid-park. Reachability needs NO out-of-band knowledge of the run id, because the map write is what publishes the id to listSuspendedRuns during the window - the same list-then-open consumer #16031 was written for. Chose a CONTROL PIN over a comment (new file suspended-run-mid-park-eviction-window.test.ts, 5 tests) because a pin makes the boundary executable and carries the reachability measurement, which a comment could only assert; two short comments at the map write and on evictConsumedSuspension's docblock point at it. The pin asserts the BOUNDED outcome only - still resumable through the store-first strict loader and resuming end to end, merely omitted from the cache-only listing, with listSuspendedRunsDurable unaffected - plus controls for no-store and for a read that throws. Nothing widens the cache-only marking, adds a lock, or moves the save. ONE MEASURED CASE ESCAPES BOUND 1 and is pinned but deliberately NOT fixed - see open_questions. Two half-states to note: the skip-changeset label is still OWED (GraphQL pool exhausted mid-run, details in tests), and the engine-double ledger collision the dispatch warned about did not materialise.",

(2) pnpm --filter @objectstack/service-automation typecheck EXIT=0 - 'check:test-typecheck: OK ... 0 file(s) / 0 error(s)'. Coverage of the NEW file proved, not assumed: tsc -p tsconfig.test.json --noEmit --listFiles and tsc -p tsconfig.json --noEmit --listFiles each name suspended-run-mid-park-eviction-window.test.ts exactly once (both EXIT=0). (3) pnpm --filter @objectstack/service-automation test EXIT=0 - 'Test Files 117 passed (117), Tests 1400 passed (1400)'. (4) ABLATION, committed before mutating. Removed this.evictConsumedSuspension(runId) from loadSuspendedRunStrict. Mutation proved ON DISK by git hash-object delta 21892e2381a4a8340eb86a8c4236812142e930a7 -> 1c8e0a896475d2409db25d891d049e88aee0ee7f PLUS anchored counts (call site 2 -> 1, injected marker 0 -> 1); pre-check asserted the tree equalled the HEAD blob before mutating; restore ran under trap ... EXIT INT TERM on an ABSOLUTE path via git checkout HEAD -- ABSOLUTE_PATH. Ablated run EXIT=1, 'Tests 3 failed | 2 passed (5)' - the three that depend on the eviction firing turned red (both THE WINDOW cases and FINDING), the two CONTROLs that assert nothing is evicted stayed green. That is the direction I predicted before running, not a template default. Restore proved by blob equality back to 21892e23, empty git diff HEAD (0 bytes), counts back to 2 / 0; restored run EXIT=0, 5 passed. NO REBUILD on either leg is correct here and is stated rather than skipped: the pin reaches engine.ts by a relative same-package specifier, so vitest resolves src/engine.ts, never a dist/. (5) GATE FAMILY derived mechanically on the FINAL head: node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack, no paths passed, no hand-built list. Reconciliation line: 46 families (34 by path + 7 by change kind + 7 declared whole-tree, 2 reached both ways). All 46 taken from --commands and run; ALL EXIT=0. Two first returned EXIT=3 = PREREQUISITE NOT MET, which I did NOT record as a pass: pnpm check:dual-build-cjs-loads (needed built output; after turbo run build across packages, EXIT=0, '103 published require entry point(s) across 66 package(s) load') and pnpm check:type-check-debt (needed the built closure, then OOM'd inside tsc because the gate propagates the caller's NODE_OPTIONS and my --max-old-space-size=4096 was the tighter ceiling - the gate says so itself; re-run at 8192 with 14.9 GB free, EXIT=0, '12 ledger entr(ies) re-measured in 93.2s, 140 raw tsc error(s) total, none above its recorded number'). check:engine-double-contract EXIT=0 with scripts/engine-double-contract.pinned.json UNMODIFIED - the pin's fake is a SuspendedRunStore, not an ObjectQL engine double, so the collision with PR #16128 on that ledger did not materialise and no --write run was needed. UNMEASURED, named rather than implied: the 6 families whose argv takes a value from the workflow ($RUNNER_TEMP, $ {{ matrix.shard }}) - two check-shard-attestation.mjs invocations, check-test-completeness.mjs twice, and check-cross-package-test-inputs.mjs --union-into. The derivation refuses to invent a local invocation and so do I. I assert nothing about CI state. CHANNEL: REST is closed for this session - a repo-scoped probe returned 403 'GitHub access is not enabled for this session', the documented session-gate shape - so all GitHub work went via MCP. The GraphQL pool then hit 'API rate limit already exceeded' on the label read AFTER the PR was opened. SKIP-CHANGESET LABEL IS OWED, NOT APPLIED: applying it needs read -> union -> whole-group write, and the read half is what the pool refused; a blind whole-group write would have stripped whatever pr-automation had already applied, so I did not take it. Please apply skip-changeset to PR #16150 (judged, not defaulted: one new test file plus comments, releases nothing from any package). Until it is on, Check Changeset will read red for the stated reason.",

分诊：补
priority:p3+tests（pm:dispatched/domain:services/finding保留）填卡席写「⛔ Priority and any further lane grading are triage's」——本席给出 p3，并补
tests（因为按卡片自己的判断，最可能的产出是一条 control pin，而 PR #16150 的标题test(service-automation): pin the mid-park eviction window证实了这一点）。落点核实（
origin/main，本轮实读）卡片明确要求
⚠️ re-locate them, main moves——本席照做，三个行号在今天的 main 上全部仍然精确：packages/services/service-automation/src/engine.ts :2036 private async persistSuspendedRun(run: SuspendedRun): Promise<void> { :2037 this.suspendedRuns.set(run.runId, run); ← 卡片的 :2037 ✅ :2040 await this.store.save(run); ← 卡片的 :2040 ✅ :2041-2042 // [#13617] The store now holds this pause, so it — not this map … :2051 this.cacheOnlySuspensions.add(run.runId); ← 卡片的 :2051 ✅（卡片是按
1157e7b72读的；main 已经动过，但这三行没漂。记在此处，省下一个人再核一遍。）为什么定 p3
- 卡片自己把边界论证完整地写下来了，且论证成立：
loadSuspendedRunStrict在挂了 store 时是 store-first，所以 run 仍可恢复——被驱逐的 map 条目是缓存，不是权威副本；listSuspendedRuns()只是漏报，而漏报本来就在该方法自陈的容差之内（多报从来不在——这正是 fix(service-automation): evict a suspension consumed by another replica, so the run listings stop reporting phantoms #16031 依赖的那条不对称）。⇒ 在这两条界内，没有任何东西丢失或出错。 - 它不是契约缺陷，卡片开篇就用最重的措辞说清了（"
⚠️ This is NOT a contract defect, and the card must not be worked as one."）——本席背书并原样转达给承接席。 - ⛔ 不降到无优先级：一条未被钉住的边界会变成口口相传的传说（卡片原话："an unpinned limit becomes folklore, and the next reader cannot tell a deliberate boundary from an oversight"）。这正是本卡存在的全部理由，也是它值得一个 p3 而不是被关掉的理由。
- ⛔ 不升 p2：升到 p2 的是它的复合案例 service-automation: a failed suspension save whose window was already read loses the run outright — and the error record tells the operator the opposite #16151——那一个测量上逃出了这里的第一条界（run 在进程内直接丢失，且
:2064-2065的错误消息在最危险的方向上是假的），本席已把它定为 p2。两卡的优先级差，正好是「有界」与「逃界」的差。
⭐ 卡片最该被继承的三条，本席原样背书
① 明确禁止的修法。
⛔ Do not "fix" this by widening the cache-only marking, adding a lock, or moving the save before the map write, unless a measurement shows the harm escapes those two bounds.
⚠️ 这条现在有了新的分量：#16151 正是那个「测量显示危害逃出界外」的案例——但它逃出的是复合交织下的界，且它自己也把「在 await 之前就标记 cache-only」（会削弱 #13617 的 store-authority 不变式）排除在可单方面采取的范围之外。⇒ 本卡的禁令不因 #16151 的存在而解除；承接本卡的人仍只应产出注释或 pin。② pin 强于注释，理由说得对。
⭐ A pin is the stronger form, because it makes the boundary executable rather than a claim in a comment that later drifts.
这正是本 lane 一整天在追的那个失败类的反面：一条写在注释里的边界会腐烂且不会有人发现；一条被驱动的 pin 会在腐烂时变红。 卡片要求承接席说明自己选了哪一种以及为什么——本席把这条提为验收条件。
③ 「不可达」也是结论，不是关卡的理由。
it is not established that the interleaving is reachable on any shipped composition; if it turns out not to be, that is a finding and belongs in the pin's own text, not a reason to close the card silently.
⭐ 本席特别背书这一条。「测不出来」与「不存在」是两回事（纪律②：零不等于缺席，除非同一次读取里有正控制）。若承接席测出该交织在任何已发运的组合上都不可达，那个结论必须写进 pin 的正文，让下一个人知道它被测过——⛔ 而不是静默关卡，那会让下一个人从头再测一遍。
⚠️ 与 #16151 的关系——承接席必读#16150（本卡的 PR）已把 #16151 的复合案例按其实测行为钉住而未修复。 #16151 的填卡席明确标注：
⛔ It is pinned as measured, not as desired — do not read the pin as endorsing the current behaviour.
⇒ 本卡与 #16151 共用同一条 PR 里的 pin 基础设施，但结论相反：本卡的 pin 断言的是「有界，且这是刻意的」；#16151 那条红测试断言的是「逃界了，等着被改绿」。⛔ 承接席不得把两者混为一谈——把 #16151 的红测试"改绿"的正确方式是修复
persistSuspendedRun的 catch 路径（#16151 的 C 支），⛔ 不是把它重新表述成一条本卡式的「有界」断言。分离关系（卡片给出，本席认同）：#15832（Note 1 已随 #16031 落地，Note 2 的 store 半在 PR #16128）与 #16033（
ObjectQL.delete声明Promise<any>而IDataDriver.deleteMany声明Promise<number>）机制均不同，⛔ 不重复、不合并。
⛔ 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）。

Filed by the
domain:servicesPM seat as the follow-up the director flagged when reviewing PR #16031 (which landed as1157e7b72). ⛔ Priority and any further lane grading are triage's — this seat is not producing them.The window
AutomationEngine.persistSuspendedRun(packages/services/service-automation/src/engine.ts, line numbers as read at1157e7b72—:2037this.suspendedRuns:2040await store.save(...):2051cacheOnlySuspensionsis added only if that save failed⇒ Between
:2037and the resolution of:2040, the entry is in the map but is not yet marked cache-only. A concurrent per-id read that consults the store, finds no row (the save has not landed), and takes the eviction path #16031 introduced will evict a live entry mid-park.Why it is bounded — the part that must survive into whatever is written
loadSuspendedRunStrictis store-first when a store is attached, so the run stays resumable: the authoritative copy is the store's, and the evicted map entry is a cache.listSuspendedRuns()merely omits the run. Under-reporting is already inside that method's declared latitude; over-reporting never was — which is exactly the asymmetry fix(service-automation): evict a suspension consumed by another replica, so the run listings stop reporting phantoms #16031 relies on.⇒ ⛔ Do not "fix" this by widening the cache-only marking, adding a lock, or moving the save before the map write, unless a measurement shows the harm escapes those two bounds. The likely correct output is one of:
evictConsumedSuspension(and/or at:2037) naming the window and why it is inside the declared latitude, or⭐ A pin is the stronger form, because it makes the boundary executable rather than a claim in a comment that later drifts. Whoever takes this should say which they chose and why.
What is NOT established
⛔ This seat has not measured the window — it is the director's reading from the #16031 review, recorded here rather than re-derived, and re-measuring it is step 1 for whoever takes this. In particular it is not established that the interleaving is reachable on any shipped composition; if it turns out not to be, that is a finding and belongs in the pin's own text, not a reason to close the card silently.
Deliberately separate
'unsupported'branch answers only after its conditional delete has already been issued #15832 — Note 1 landed in fix(service-automation): evict a suspension consumed by another replica, so the run listings stop reporting phantoms #16031; Note 2's store half is PR fix(service-automation): decide the claim capability before the compare-and-set, never after it #16128. ⛔ This is neither, and it was explicitly kept out of that card so its two notes did not become three.ObjectQL.deletedeclaresPromise<any>, so a store cannot ask whether a multi-delete returns an affected-row count without first performing it — the cross-lane half of #15832 #16033 — the contract half (ObjectQL.deletedeclaresPromise<any>whileIDataDriver.deleteManydeclaresPromise<number>).
