docs(pm): encode the 2026-08-31 director rulings — ruling-record carrier, and cross-fire round continuation

[os-justin]

Fixes #13766
Fixes #13765

Two-card, one-file flight: encodes the two mechanical 余项 from the 2026-08-31 director batch #20 rulings (items ⑤ and ④, director session session_01KGtaLpkW1mycWgkbSb3H6t) into .claude/skills/pm-dispatch/SKILL.md — one sentence per card, per-member commits.

Maintainer verbatim (batch reply, untranslated): 「#13765 是分诊席自己的问题，完全可以处理完，他的定时到达时如果上一批还没处理完就接着处理呗。其他同意」

Commit 1 — authoritative carrier of a recorded ruling (ruling ⑤)

Added to the 升级与决策 section, immediately after the atomic ruling-recording clause (③ 四件同笔): the authoritative carrier of "a ruling is recorded" is the director seat's per-sitting closing summary ledger; the ruling comment on the card is demoted to elaboration — still the first landing for execution and review, but existence disputes are settled by the ledger.

Ruling comment (2026-08-31, verbatim, untranslated):

B 生效:自本裁起,「一条裁决已记录」的权威载体 = 总监席每场收工的摘要台账(座位贴 #12708 世系,条目最小形状照既有:卡 · 权威引文 · 方向 · 状态转移);卡上的裁决评论降为详注(elaboration)—— 详注仍是执行与复核的第一落点,但存在性之争以台账为准

Commit 2 — a fire arriving mid-round continues the round (ruling ④)

Added to the 分诊座位职责 section's 发现分诊轮 paragraph, immediately after the 断点续跑 clause: a fire is a continuation trigger, not a reopen obligation; the backlog continues oldest-first, not re-sorted by a new fire; crossing fires is not carded as a contradiction.

Ruling comment (2026-08-31, verbatim, untranslated):

溢出语义由本裁补齐:定时到达时上一批还没处理完 ⇒ 接着处理 —— fire 是接续触发,不是重开义务;一个清空轮次可以跨多个 fire,存量按最老优先继续消化,⛔ 不因新 fire 重排、不因跨 fire 视为违规

把第 2 条接续语义写进 SKILL 分诊席职责段(一句话量级的澄清:「fire 到达时上一轮未清空 ⇒ 接续处理,轮次可跨 fire」),防止下一任席位把「跨 fire 未清空」再当矛盾立卡

Constraints honored

• No ceiling raise: SKILL.md 984 → 989 lines (+5), ceiling 1005 untouched. Gate verdict at head 70a48ae: "check-skill-line-ratchet: .claude/skills/pm-dispatch/SKILL.md is 989 lines (ceiling 1005; headroom 16)". Per-line 120-byte budget also honored (a first draft tripped it at 123B; rewrapped).
• scripts/pm/check-skill-line-ratchet.mjs untouched (serialized under another in-flight PR) — the diff is exactly one file.
• No issue numbers in the file's operative text: the seat-post lineage is spelled 总监席座位贴世系, matching the file's number-free convention (check:pm-skill-id-lint: 23 files clean).
• The enforced decision-frame copy untouched — the carrier sentence sits before the frame's declaring anchor (check:skill-frame-sync: 4 copies structurally isomorphic across 3 files).

Gates (union derived by dispatch-gates.mjs from the real changed set; run at 70a48ae; exits captured by redirect before any pipe)

• Green, each by its own verdict line: check:pm-skill-ratchet · check:pm-skill-id-lint · check:skill-frame-sync · check:pm-governed-prose · check:pm-governed-merges · check:agent-test-spelling · check:doc-authoring · check:doc-formula-expressions (PREREQUISITE NOT MET on first run; measured after building @objectstack/formula and @objectstack/lint) · check:nul-bytes.
• check-governed-queue-guard: NOT MEASURED locally — it reads the workflow event payload and refuses to exit 0 without one; CI-context only.

Governed surface (.claude/**): draft PR, human merge only — auto-merge is never armed here. Docs-only diff shipping from no published package: skip-changeset.
