docs(pm-dispatch): Operational notes 22–25 from the 2026-08-10 services shift

[os-help]

Authorization (Guardrails .claude/ exemption)

.claude/ tooling change, maintainer-authorized. Verbatim instruction, given in-session by the maintainer (help@objectstack.ai) on 2026-08-10:

「更新最新的项目经理技能」

Per the Guardrails exemption path this PR quotes the authorization above, is opened as draft, and ⛔ will not be self-review-self-merged by the authoring seat — it needs a walkthrough by the maintainer or another seat before it moves.

What changed

Tail-appends four numbered entries to .claude/skills/pm-dispatch/SKILL.md → Operational notes (append-only; inserted after note 21, before the three-repo section). No existing text touched. Each note is a lesson the 2026-08-10 services-lane shift paid for first-hand and that the current skill text does not cover:

• Note 22 — queue-kick signature: no own merge_group run = rebuild transient. A PR kicked from the merge queue with no merge_group run of its own (siblings all success) was cancelled by a queue rebuild, not by a red (test(examples): pin the #7225 measurement — one persisted-row hook probe per example app (#7258) #7311, one flip re-queue → landed). Prescription: one receipted flip re-queue by the PM; a second kick on the same PR hands off to the queue steward (队列管家 Routine（三仓总管）：合并队列健康专责化 —— flaky 签名分诊 / 原样重投 / 新签名拦截 / 跨仓 pin 链停滞观测（座位 Routine 化第二例，维护者 2026-08-06 拍板） #5810). Also upgrades note 21's flip prescription from "3/3 cases" to confirmed-at-scale (every instance this shift, 6+, landed). Un-receipted re-queues are banned — they're indistinguishable from flaky hard-retries in the steward's ledger.
• Note 23 — same-account claim-race arbitration (service-storage's attachment kit carries the same 5-field callerContext projection #7141 fixed for comments #7145). All seats share one GitHub identity, so assignee carries zero information between two sessions; the claim comment's session ID + timestamp is the only tiebreaker (69-second race, first comment wins). The loser yields with a handoff comment carrying its already-done readings, not silently.
• Note 24 — producer-forced out-of-surface rider is legitimate, not REWORK. A predicate update writing a file field gives N records one file id under an exclusive-ownership model #7102 / PR fix(service-storage): refuse a predicate update that writes a file field (#7102) #7224: ADR-0112 D3 mandates the error-code ledger row (packages/spec) land in the same PR as the minting. Three acceptance criteria (loud declaration / mandatory per ADR / no atomicity-preserving split), then ACCEPT + cross-seat declaration per the fix(rest,objectql): the import dry run asks the engine for its verdict instead of predicting it (#4633) #6532 precedent. Distinguished from the existing UnknownFilterTokenError 漏诊:含非 word 字符的类占位符串({TODAY()}、{current-user-id}、{30 days ago})绕过诊断,原样下发按字面串比较(17.0.0-rc.2) #5586 note: that one covers the landing point moving packages, this one covers an extra package appearing.
• Note 25 — Bash cwd resets every call in this environment: always git -C <absolute-path>. Extends the existing cross-repo-grep rule to all git operations; a post-cd git call silently reads the wrong tree and returns a clean-looking absence — exactly the notes-6 failure shape.

Review notes

• 37 insertions, 0 deletions, single file; diff is the four notes verbatim.
• No changeset: .claude/ skill docs, not a published package (matches prior skill-update PRs).
• Requesting walkthrough: maintainer or another PM seat, per the exemption path. Points worth challenging: whether note 22's "second kick → steward" quota matches the steward charter in 队列管家 Routine（三仓总管）：合并队列健康专责化 —— flaky 签名分诊 / 原样重投 / 新签名拦截 / 跨仓 pin 链停滞观测（座位 Routine 化第二例，维护者 2026-08-06 拍板） #5810, and whether note 24's three criteria are tight enough to not open a general out-of-surface door.
