skills(pm-dispatch): a mid-task note that narrows a standing dispatch contract names the replacement owner and the moment — otherwise it manufactures a half-state (a C1 dual-carrier split measured on PR #17725 / #16804)

Filed by the skills seat (session session_01MCLBsUgfykL74aU716rzVK, GitHub os-sales) at 2026-09-12T00:47Z while grading #17710 (the domain:cli seat's R73 shift-end items) — its comment 5641485675 item 5 is a 原则错/缺 with no card of its own; the source record is #16804 comment 5641479348.

The measured instance

A mid-task note from the dispatching seat narrowed a dev's standing contract — it reserved «hang/clear needs:contract-review» to the seat — without saying who does the other half or when. The dev had already hung the PR-side carrier, then stopped and flagged rather than choosing (the right behaviour). The result was a live C1 dual-carrier split on PR #17725 / card #16804 until the seat hung the card side by hand.

The rule worth writing (one clause)

An instruction that narrows a standing contract mid-task names the replacement owner and the moment the replacement acts; a narrowing that names neither is refused by the dev as incomplete (report blocked naming the gap) rather than executed half.

Landing

.claude/skills/pm-dispatch/references/dispatch-runbook.md 〈派发词构造细则〉, one line paid by density (the file is ratcheted); references/** only ⇒ default-tier build, skills-seat contract-tier review; governed ⇒ human terminal. Not SKILL.md (the runbook is where the dispatch-word rules live). Hot-file: dispatch-runbook.md is free at filing.

Dedup

MCP search_issues (repo-scoped, natural-language query on the narrowing-instruction / replacement-owner shape) → 3 hits, all closed and on other subjects (#16836 the contract-review FAIL end-state, #11134 the landing window, #8683 close-out debt) — the channel was live and none is this rule.

domain:skills · pm:queue · priority:p3 · Task (self-triaged at filing under the lane's standing exception).

Dispatched — R1 wave 7, 2026-09-12T05:03Z, mode:subagent, build tier opus (references/** only), skills-seat review at the contract-review tier. Claim 5643622852 is the dev's identity; branch claude/issue-17729-narrowing-names-replacement-owner, cut from origin/main at dispatch (8fa3fe63). Deliverable: the card's one-clause rule in 〈派发词构造细则〉 — a mid-task note that narrows a standing dispatch contract names the replacement owner and the moment the replacement acts; a narrowing naming neither is refused by the dev as incomplete (report blocked naming the gap) rather than executed half — paid by density on an existing bullet of that section (the seat measured 97 / 70 / 69 free bytes on lines 222 / 211 / 230 at claim time; pick the host whose sense the clause extends, ≤ 120 B, ⛔ no new line, no rule deleted, ceiling untouched). Terminal: governed ⇒ draft at the human terminal with Fixes #17729. In flight on the lane: 3 (#17098, #17626, this card) + the #17280 governed half at the human terminal.

All four elements are carried: 中途收窄标准条款 (a) / 须点名替换承接人 (b) / 与时点 (c) / 缺一 dev 报 blocked 不半执行 (d). Host choice is not a trade-off: re-measured free bytes in the section are 222=97, 211=70, 230=69, 214=63, 228=63, 201=61, so line 222 is both the semantic host and the only bullet with room for a 96-byte clause. Zone 2 item 4 re-checked by git grep over .claude/skills/pm-dispatch/** (替换 / 承接 / 收窄 with 契约/条款): no existing line states the replacement-owner rule, so the premise stands.

Ratchet verdict lines: '✓ check-skill-line-ratchet: .claude/skills/pm-dispatch/references/dispatch-runbook.md is 241 lines (ceiling 241; headroom 0).' and '… widest table row is 0 bytes (pin 0; headroom 0).'

Control-char self-scan (grep -naP over the control ranges) on the changed file: no hits. eslint narrowing is total rather than sampled: pnpm exec eslint --no-inline-config --format json over the one changed file reports 'File ignored because no matching configuration was supplied' (population 1 file, 0 linted, no eslint config matches .md), so the diff cannot move any untouched file's verdict; repo-wide pnpm lint stays CI's run. No ablation applies — the deliverable is one prose clause in a ratcheted instruction file, with no code path to mutate; the ratchet and the byte cap are the measurements. No changeset: .claude/** is the skip-changeset fast track (nothing in any package's files[] moves); label applied additively via REST POST .../issues/17794/labels and read back — before ['size/xs'], target ['skip-changeset'], readback ['size/xs','skip-changeset'] = union, nothing stripped.

ACCEPT — PR #17794 (head 902f019c) reviewed in-seat at the contract-review tier; governed (.claude/**) ⇒ four-piece at the human terminal (skills seat, session session_01MCLBsUgfykL74aU716rzVK, 2026-09-12T05:20Z).

Implemented-by: os-dev subagent on claude/issue-17729-narrowing-names-replacement-owner (claim 5643622852; build tier opus; mode:subagent; report on this card). Reviewed-by: session_01MCLBsUgfykL74aU716rzVK (the skills seat) — independence pair holds.
One clause, one file, paid by density: references/dispatch-runbook.md line 222 「- ⛔ 不硬造 diff。」 → 「- ⛔ 不硬造 diff。中途收窄标准条款须点名替换承接人与时点,缺一 dev 报 blocked 不半执行。」 — 24 → 119 B (cap 120), the file stays 241/241, no line added, no rule deleted, no re-wrap, ceiling untouched. The host is the in-flight-overlap interception group (lines 220–222), the runbook's only rule group about a note sent to a dev mid-task — the semantic host and, by the seat's own measurement (97 free bytes), the only bullet with room. All four elements present: a mid-task narrowing of a standing clause (中途收窄标准条款) / names the replacement owner (须点名替换承接人) / and the moment (与时点) / missing either ⇒ the dev reports blocked rather than executing half (缺一 dev 报 blocked 不半执行).
Seat's own readings: the diff is that one line (read from the PR diff); the head file is 241 lines; body first line Fixes #17729, one footer; CI on 902f019c at 05:20Z 9 success / 11 skipped / 4 in progress — the human merge waits for green per true-green.md. Premise re-checked by the dev: no existing line in .claude/skills/pm-dispatch/** states the replacement-owner rule.
Evidence: 14 derived gates all exit 0, reconciled with --ran on the final diff; ratchet verdict 241 lines (ceiling 241; headroom 0); governed test exit 3 GOVERNED; doc-formula-expressions exit 3 PREREQUISITE NOT MET on the first pass, exit 0 after the two packages were built under the verify lock (held 208 s); no ablation applies to a prose clause.
Note carried: the dispatch word's gate-derivation spelling (a path passed to dispatch-gates.mjs --commands) differs from os-dev.md's no-path form; the dev derived without paths per os-dev.md and the two agree here — the seat's later dispatch words use the no-path form.
Landing plan: draft kept, needs-user-decision on the PR, 速读 comment, reviewers os-zhuang + hotlong; ⛔ no ready flip / queue / auto-merge by this seat. On MERGED: landing record, pm:dispatched + assignee cleared with read-back; dispatch-runbook.md chain free.

Landing record — PR #17794 MERGED 2026-09-12T06:28Z through the merge queue as a77b4e92, merged by os-zhuang (the human merge is the review record for the governed runbook; four-piece was on the PR; skills-seat ACCEPT 5643727159, 速读 5643727345). Content verified on origin/main by git at 2026-09-12T06:30Z: references/dispatch-runbook.md line 222 carries 「中途收窄标准条款须点名替换承接人与时点,缺一 dev 报 blocked 不半执行」, the file is 241 lines, and the merge sha is an ancestor of origin/main. The card was closed by the PR's Fixes line. Residue cleared in this same act: pm:dispatched and the assignee removed. In force: a mid-task narrowing that names neither its replacement owner nor the moment is refused by the dev as incomplete. Skills seat, session session_01MCLBsUgfykL74aU716rzVK, 2026-09-12T06:30Z.
