docs(pm-skill): dispatch-runbook.md — the level rationale names p1–p3 and the sweep-batch line reads as the finding threshold (two riders from batch #62)

[claude]

Filed by the skills lane seat (session session_019RfFHiRCSs3JXLK4cwcfox, os-steve) at flight Z's ACCEPT (PR #16486), 2026-09-07T04:1xZ — two line-neutral riders that fell outside that flight's declared file surface.

What

.claude/skills/pm-dispatch/references/dispatch-runbook.md (241/241, fold-paid):

1. Line 7's level rationale (「级序理由:p0 是显式裁定,blocking 一张挡多张,bug 是已坏的不变量先于增强,卡龄防饿死。」) names no p1–p3 level; after PR docs(pm-dispatch): the batch #62 skill folds — file-surface batch independence, priority in the selection order, the readings-ledger ceiling exception, the suite-event head re-read, the director carve-out #16486 the selection order reads p1 > p2 > p3 > 无级, so the rationale gains the level clause in the same register.
2. The sweep-batch line 「范围外发现照旧单开」 reads as the finding admission threshold (three classes file a card; the rest goes to the PR's 验收备注), per the rider recorded on pm-dispatch: the selection order never reads priority:p1/p2/p3 — an older p3 outranks a newer p2 inside 「其余」; write priority into 取卡全序 #16352 (comment 5560413144).

Ruling

One XS governed PR; rules-only; each line paid by a same-file fold; check:skill-frame-sync, the ratchet and the id-lint green.

Serial

Blocked-by: #16386

Dispatched after PR #16486 merges (the order line it restates must be on main first).

Claim: PM loop round 1 — flight G (wave 2, into flight A's slot): the two line-neutral riders in references/dispatch-runbook.md recorded at flight Z's ACCEPT — the level rationale gains the p1 > p2 > p3 > 无级 clause, and the sweep-batch line 「范围外发现照旧单开」 reads as the finding admission threshold (three classes file a card; the rest goes to the PR's 验收备注).

Rider 1: the level rationale gains a second line — 「级别半边:p1–p3 是分诊已裁的显式排序;无级末位是分诊缺口,不是一个已裁的低优先级。」 — because the existing rationale line measures 115 bytes against the 120-byte cap and the level clause is at least 39 bytes, so PM guess G1's in-line rewrite was falsified for this rider and the fold route was taken instead. Rider 2 was rewritten in place, line-neutral: 「范围外发现照旧单开」 became 「范围外发现按立卡三类门槛分流,三类外进验收备注、不单开」, pointing at the threshold without restating the three classes. The added line is paid by deleting one same-file restatement (the emergency section's summary), so the file is 241 lines before and after and every line stays at or under 120 bytes. Assignee untouched, no second claim posted.",

No ablation and no reverse verification: the diff is three rules lines and authors no gate, so there is nothing whose failure mode could be mutated; the template's ablation field does not apply rather than being skipped. CI at report time: Check Changeset, Check PR Size, Governed Surface Queue Guard, Test Core, Dogfood Regression Gate, both single-writer guards and Part-of-PR guard all `success`; `Lint & Repo Gates` and the four `Type Check ·` jobs still `in_progress`.",

ACCEPT — flight G, PR #16603 at head 4d6cd158, contract-tier review in seat; the dev's report is 5570456413. Every reading below is the seat's own, on GitHub, on refs/pull/16603/head and on this checkout at ac9376a7.

• PR shape: draft, base main, first line Fixes #16490, nothing else keyword-shaped; Part-of guard and both single-claim guards green.
• Files (get_files via the head filter): exactly one — .claude/skills/pm-dispatch/references/dispatch-runbook.md, +2/−2; skip-changeset present; no content/docs/releases/**.
• Head measured: 241 lines (wc -l on the blob), widest line 120 bytes (awk, LC_ALL=C), #[0-9]{3,} zero hits.
• Diff read line by line: rider 1 as a new line 8 「级别半边:p1–p3 是分诊已裁的显式排序;无级末位是分诊缺口,不是一个已裁的低优先级。」 — matches SKILL.md's own tail (无级卡轮报记分诊缺口) and restates no order; rider 2 rewritten in place at line 30 「…范围外发现按立卡三类门槛分流,三类外进验收备注、不单开。」 — points at the threshold without restating the three classes; PR skills(pm-dispatch, os-dev): five measured refinements to the finding admission threshold #16557's 20-sample line (33) untouched. The fold: 「紧急通道改的是节奏,不是生产者数目。」 removed — a summary with no test of its own; its two halves survive in the line above it (the single-producer discipline with its operative test) and the section's trigger line. Currency is a deletion, not a re-wrap.
• Serial: git merge-tree --write-tree --name-only origin/main refs/pr/16603 clean (seat's own run); the dev's overlap sweep over the six open pm-dispatch/skills/agents PR heads found no hit on this file; the file's last landing is PR skills(pm-dispatch, os-dev): five measured refinements to the finding admission threshold #16557.
• Gates: 14 derived, 14 run, 0 NOT-MEASURED (one PREREQUISITE NOT MET re-run green after the build); ratchet 241/241, id-lint 26 clean, frame-sync isomorphic, nul-bytes clean; check-governed-merges --test exit 3 (.claude/** ×1); whole-repo lint under the verify lock exit 0. CI on 4d6cd158 at 12:14Z: 28 check runs, none red; Lint & Repo Gates and four Type Check legs still in_progress — nothing here flips ready; re-read at the next patrol.
• Deviation accepted: G1 falsified (the rationale line at 115 bytes cannot take a ≥39-byte clause in place), so the brief's own fallback — a new line paid by a same-file fold — was taken; REST 403 ⇒ MCP union route for the label with read-back.

验收备注 (noted, not filed)

• The sweep block's 「五条」 are spread across three rows with items 3–5 sharing one line; not a defect. 承接者: the next seat editing ## 发现分诊轮细则, paying its own way at the ceiling.

Terminal: governed (.claude/**) ⇒ os-zhuang + hotlong requested on the draft, needs-user-decision added to the PR, the final 维护者速读 posted there; human merge. On merge this card closes by Fixes and the seat strips pm:dispatched + assignee.
