PM protocol: SKILL.md 819 → ≈300 lines of principle (red lines · state model · entry · index), the dispatch / review / landing detail relocated into per-phase references, and core-rules.md retired as a duplicate (maintainer direct dispatch, batch #213 item 4)

[os-support-ai]

③ 直派任务 — maintainer direct dispatch, filed by the director seat (summon #27, session_0129ZpnaBcYZZ51rCvQiXg6C). domain:skills · tooling (the PM loop's own protocol). Takes the lane's pick order first as a 直派插队卡, ⛔ but only after the serial constraint below clears.
Re-pointed 2026-09-23T05:40Z (director seat): PR #19737 (#19061 step ③) MERGED at 2026-09-23T05:06Z as 628e55dfa — the SKILL.md :76 / dispatch-runbook.md :161 / lanes/director.md collision the serial constraint named is on origin/main; the former Blocked-by: #19061 / Unlock-action: re-check #19061 when label pm:dispatched absent lines are retired and the card returns to pm:queue as the lane's 直派插队卡. ⛔ One file stays another card's: references/contract-review.md :13 / :19 (the --template pointers) belong to #19061 step ④ (claim 5789522248, branch claude/issue-19061-step4-record-recognisers-module, scripts/pm/** + those two lines) — the dev leaves them untouched and rebases if step ④ lands first.
Re-pointed 2026-09-22T15:12Z: PR #19694 (step ②) merged at 2026-09-22T13:03Z as 7e0bfce40, but #19061 step ③ (claim 5778141422, skills seat 1, 2026-09-22T14:16Z) declares SKILL.md :76, dispatch-runbook.md :161 and lanes/director.md among its riders — the same collision the serial constraint below names; the former Unlock-action: re-check PR #19694 line is retired.

Provenance (who / verbatim / where): the maintainer, chat with the director seat, 2026-09-22, answering decision batch #213 — 「1 2 4 同意」. Item 4 as presented: 「协议主文 819 → 约 300 行(红线 + 状态模型 + 入口 + 索引),派发 / 复核 / 入队细则各成一份按阶段读的 reference;同时删 core-rules.md 双份」. Standing directions it serves: 「更新你的技能」 (batch #211 standing rulings on #19647) and the maintainer's repeated 「淡化门禁 / 创业阶段不扩散」.

Readings (director seat, origin/main 40626bdca6, 2026-09-22T10:3xZ)

• .claude/skills/pm-dispatch/SKILL.md: 819 lines / 76.7 KB, 201 「⛔」 lines (≈ one per four lines). references/core-rules.md: 151 lines, self-described at SKILL.md:43 as 「本文的子集」 with the rule 「一条规则在本文与核心条款一处改动,另一处同 PR 同改」 — a maintained duplicate. references/*.md + references/lanes/*.md: 1,590 + 360 lines. An execution seat's first read per fire ≈ SKILL.md + core-rules + its lane file + AGENTS.md ≈ 178 KB.
• Industry reading (director's comparison, 2026-09-22): peer fleets run on one short readiness/conventions page plus per-repo instructions; the length here is the cost of every seat re-reading detail it does not need on that fire.
• Serial constraint: PR pm(skills): retire the clause-② gate text — label hang/clear, --pair, double carrier, independence requirement (step ②) #19694 (Part of #19061 step ②, skills seat, draft) touches SKILL.md, references/contract-review.md, references/core-rules.md, references/platform-readings.md — the same files. ⛔ This card starts only after PR pm(skills): retire the clause-② gate text — label hang/clear, --pair, double carrier, independence requirement (step ②) #19694 is on origin/main (the Unlock-action: line above); a dev who starts earlier will collide.

Ruled shape — ⛔ not open for re-design

1. Relocation, not deletion, and no semantic change. Every rule line of today's SKILL.md ends up in exactly one place: SKILL.md if it is principle (红线, 优先级, 入口与角色 with its args table, 状态模型 table, 全体座位的不变量, 域车道 table, the four-axis block in 升级与决策 — the single copy check:skill-frame-sync guards — 机械守卫索引, 模板与表), or one per-phase reference otherwise (suggested shape: references/seat-lifecycle.md for 开轮互斥 / 座位贴 / 收班, references/triage-duties.md, references/execution-duties.md for 候选 / 认领 / 派发 / 收集 / 复核, and the existing landing-operations.md absorbing 入队与落地; the dev may choose different file names and says why). Proof in the PR body: the count of 「⛔」 lines across SKILL.md + references/** before == after, and a table mapping each moved section to its destination.
2. SKILL.md lands at ≈ 300 lines (a ceiling of 340); scripts/pm/check-skill-line-ratchet.mjs's ceiling for it is lowered to the landed count in the same PR (降恒合法, no maintainer citation needed for a decrease).
3. references/core-rules.md is deleted. Every pointer to it is retargeted or removed: SKILL.md:43 and :89, references/lanes/director.md, scripts/pm/git-history.mjs's 三章程 touch list, and whatever git grep -n core-rules finds on the head. Where a rule reads differently in the two files, SKILL.md's wording wins (core-rules is the declared subset).
4. Each phase reference opens with one line saying which seat reads it on which fire, so a seat loads only its phase.
5. ⛔ No new rule, ⛔ no rule dropped, ⛔ no gate, hook, ratchet or roster added (新增门禁默认否); ⛔ no change to os-dev.md, AGENTS.md, skills/**. check:pm-skill-ratchet, check:pm-skill-id-lint, check:skill-frame-sync, check:skill-frame-freshness, check:pm-governed-prose green on the head.
6. Clause-②: no. Tier S (.claude/**): built at CONTRACT_REVIEW_TIER (强制条款① — the protocol semantic surface), landed by the skills seat after an in-seat at-tier ## Contract review PASS through the queue; skip-changeset. One PR, Fixes this card.

Claim: PM loop round R2 (skills seat 1) — batch 3 on the maintainer's 「后续并发降到3」; in flight 2 → 3 (#18964's PR #19792 is delivered and holds no slot); the lane's 直派插队卡 taken first by the pick order, as the card says
Session: session_01Wnstp2kTth7sGXfr8fXypc
Branch: claude/issue-19716-skill-md-principle-only
Worktree: objectstack-issue-19716
Domain: domain:skills
Seat: domain:skills#1
File surface: .claude/skills/pm-dispatch/SKILL.md (815 lines on 2cf9db7c4, ceiling 819 → lands at ≈ 300, ceiling ≤ 340 lowered in the same PR), .claude/skills/pm-dispatch/references/core-rules.md (deleted), new per-phase references under .claude/skills/pm-dispatch/references/ (the dev names them and says why), references/landing-operations.md (absorbs 入队与落地; 69 / 69 today — the moved lines come with their ceiling by declared cross-file moves), references/lanes/director.md and scripts/pm/git-history.mjs (core-rules pointers), scripts/pm/check-skill-line-ratchet.mjs (the ceiling map: SKILL.md lowered, the new files added at their landed counts, the total never up — 降恒合法), every other core-rules / moved-section pointer git grep finds under .claude/** and scripts/pm/**. ⛔ Not this card's: references/contract-review.md :13 / :19 (#19061 step ④, claim 5789522248); references/dispatch-runbook.md, references/platform-readings.md, references/seat-post-protocol.md beyond a single core-rules pointer line if one exists there (#19777's surface, claim 5789687463 — earlier, arbitrates; rebase if it lands first); .claude/agents/os-dev.md, AGENTS.md, skills/** (the card's own ⛔). Relocation, not deletion: the count of 「⛔」 lines across SKILL.md + references/** is equal before and after.
Container & model: L, mode:subagent (this seat's subagent channel delivered the comparable four-file split of #19715 today; the cloud channel is the director's), model: MANDATORY fable — node scripts/pm/dispatch-gates.mjs --tier --repo objectstack-ai/objectstack over the surface at 2cf9db7c4 (2026-09-23T05:50Z) printed verbatim: "Model tier — MANDATORY: claude-fable-5-1 (derived from the file surface, not recalled)." (强制条款①: the protocol semantic surface). Governed: .claude/** ⇒ Tier S — the ## Contract review record rendered in-seat at CONTRACT_REVIEW_TIER, every check green, then the seat lands it through the queue.
Clause-②: no
Thread-read: none
Ruling-ref: the card body — the maintainer's 「1 2 4 同意」 on decision batch #213 (item 4, chat with the director seat, 2026-09-22), executed as a 直派 by the director seat (summon #27) and re-pointed at 05:40 UTC of this date (the card carries no comment); the ruled shape's six items are the contract, ⛔ not open for re-design.
Serial constraints cleared: 16 open PRs' file lists read at claim time — only PR #19792 (#18964, this seat's, one word at SKILL.md :266, record PASS 5789722320, landing on green) touches the surface: the dev starts from origin/main and carries ruling 5780497628's wording (:266 without 「本车道」) wherever that sentence lands, merging origin/main before the PR opens; the fleet's pm:dispatched claims read across lanes: #19061 step ④ (this seat — contract-review.md :13 / :19 excluded above), #19146 (this seat — os-dev.md, excluded), #19777 (os-support-ai, cloud — the three one-line files named above, excluded beyond a pointer line), #18682 / #14512 name SKILL.md in prose only; git ls-remote --heads origin for issue-19716: no branch.

Dispatch basis: a p1 直派插队卡 on the maintainer's word (batch #213 item 4) and the director's re-point of this date (the serial constraint on PR #19737 spent at 05:06 UTC); 北极星「优先级」第 3 条 read fresh in this act (objectstack non-epic p0 0 · p1 28; objectui p0 0 · p1 8) — a p1 card is not what the rule bars, and the tooling label rides a maintainer's direct dispatch (#202 B is the default rule, the direct word sits above it — the triage seat's own reading on #16949). Premise re-read on origin/main by the dev before editing: the section inventory, the 「⛔」 count, the ceiling map and every pointer are measured, not recalled; premise_still_valid: false is a first-class outcome.

ACCEPT — domain:skills seat 1 (session_01Wnstp2kTth7sGXfr8fXypc, seat post #7623), 2026-09-23T07:31Z — PR #19805 at head f20de622096a24ba951f0d21ce2137ce80a193f5 (round 0).

Checklist, read against GitHub and the fetched head on a review worktree, not the report: draft, base main, first line Fixes #19716, Clause-②: no on the claim; nine commits on merge-base de4ed33fd (one per destination, the deletion, the ratchet map, a merge); 29 files, +623 / −710 — SKILL.md 815 → 319 lines of principle (the four-axis block byte-identical at :241–:261, md5 abff5f852c8fd09b79ec0623439aa4f0; the ruled :266 sentence at :175), six phase references each opening with its reader line, core-rules.md deleted with every pointer retargeted, the ratchet map lowered / extended with the total down 477 lines; os-dev.md, AGENTS.md, skills/**, dispatch-runbook.md and contract-review.md :13 / :19 untouched. Relocation proven by the seat's own multiset diff (only pointer retargets, heading levels, reader lines, the index table and the three lines naming the deleted duplicate differ) and by the 「⛔」-line count 558 == 558 with the duplicate's 59 excluded. Gates re-run by the seat at the head: check:pm-skill-ratchet, check:pm-skill-id-lint, check:skill-frame-sync, check:skill-frame-freshness, check:pm-governed-prose, check:doc-authoring, check:pm-expected-skips — all 0; the half-state (4897) and harness-current (26) self-tests 0; check-governed-merges.mjs --pr 19805 exit 3 GOVERNED Tier S (.claude/** ×26, 1,333 lines). The dev's 50-family derivation reconciled --ran 50 / 50 / 0. CI at this head: 33 latest-per-name check runs — 23 success, 10 skipped, 0 in progress, 0 other (the seat's read at 07:31 UTC of this date, after the check-suite completion); check-expected-skips.mjs --pr 19805 0 (every skipped run in the roster). Record: 5790585951 (PASS, rendered in-seat at the served tier). Report 5790526384 parses; mcp_calls 0; three REST writes through the fleet-write relay plus three pushes; no body PATCH by the dev.

The dev's two open questions, graded in-lane: (1) the stale docblock attributions → A (leave; one copy dies with PR #19803, the guard's goes at its next touch); (2) 319 lines against ≈ 300 → A (the ceiling of 340 holds; the excess is gate-anchored text and the index).

Deviations recorded, none blocking: two phase files beyond the suggested four (cross-seat sections; 367 would breach 340); the path-fork block kept in SKILL.md for its gate anchors; headroom-0 pointer lines cite the file without the heading; :42 / :44 dropped as pointers to a deleted object; the dispatch-gates battery re-run detached.

Landing: Tier S — the seat readies the PR and arms auto-merge (SQUASH) through the CCR routes in this act; at MERGED the card closes by Fixes, the seat takes pm:dispatched and the assignee off, confirms the tree on origin/main by content (319 / six files / no core-rules), re-reads the harness drift against the new tree, and removes the review worktree.
