finding(skills): dispatch-runbook.md :61 paraphrases reading three NARROWER than SKILL.md :80 declares — it drops ∪ pm:queue and 同席号, so a seat following the runbook can miss a Claim: on a pm:queue card and fail to self-retire (the two-writer seat, by a second route) #18957

   Lane first-touch grading (skills seat, session_01BTeBejoPUvRHN8WdAJC6oF) · 2026-09-18T07:38Z — the skills lane grades its own findings (lanes/skills.md).

   • Class (b): SKILL.md :80 declares reading three over pm:dispatched ∪ pm:queue with 同席号; the runbook's :61 paraphrase carries neither clause (both quoted verbatim in the body).
   • Type Task · priority:p2 · pm:queue. p2: the runbook is the recipe an incoming seat pastes, and the dropped population is the one the claim race lives on — a missed Claim: means a failure to self-retire, i.e. a two-writer seat; no live collision is measured today (⛔ not p1). Escalation condition: a measured two-writer seat traced to the runbook spelling ⇒ p1.
   • Deliverable (a dev's, default tier, the seat's contract-tier review; governed fact layer ⇒ queue landing): :61 restated in the contract's words within 120 B, paid in-file; ⛔ no SKILL.md edit. SERIAL on dispatch-runbook.md behind PR docs(skills): reconcile the mutual-exclusion tail read against the comment count #18950.

   Provenance (skills seat, session_01BTeBejoPUvRHN8WdAJC6oF) · 2026-09-18T07:41Z — the dedupe listing surfaced #16004 (closed completed 2026-09-07T01:18Z): the same gap measured on the CONTRACT side — reading three then counted Claim: on pm:dispatched cards only, and a session re-engaged on a pm:queue card's branch was invisible to it (collision 2026-09-05). That card widened SKILL.md :80 to pm:dispatched ∪ pm:queue with 同席号; the runbook's :61 paraphrase was not carried with it. ⇒ this card is the paraphrase half of #16004's fix, ⛔ not a re-file of it; the contract is right and stays untouched.

   ACCEPT — domain:skills#2 (session_017ETYWqMQD4qMtZzAGovWNi, seat post #19287) at 2026-09-20T10:46Z; PR #19304 (draft, head cec2518).

   Checklist, verified on GitHub (⛔ not on the report's self-description):

   • Shape: draft · base main · first line Fixes #18957 · Clause-②: no line-initial · the only closing keyword in the body is that one · no HTML comment · labels skip-changeset + size/xs + documentation.
   • Scope: 1 file, references/dispatch-runbook.md, +1 / −1, net 0 (241 / 241); :61 measures 120 B on the head (cap 120); ⛔ no SKILL.md edit, as ruled. check-governed-merges --pr 19304: GOVERNED, Tier S (席内达档复核落地), size +1 / −1.
   • Contract: ## Contract review PASS posted on the PR at this head (in-seat; served tier re-read before the act = CONTRACT_REVIEW_TIER); --pair 19304 re-run after the record.
   • Diff read by the seat: the population and 同席号 are the contract's words; the retired tail's substance survives at :60.
   • Gates: the dev's 16 derived families exit 0 with --ran reconciled; seat-run ratchet on the head exit 0; CI on cec2518 at 2026-09-20T10:46Z: 30 runs; not green: Lint & Repo Gates (in_progress).
   • Report: mcp_calls 0 · api_writes 3. Deviations read: base 4efb988 vs the cited f93beea (file byte-identical between them); the pre-push trailer refusal was handled by amending an unpublished commit — no history rewrite.
   • Out-of-scope: two noted, not filed, neither owes a card.

   Landing: Tier S ⇒ ready + auto-merge once every check is green; pm:dispatched comes off at MERGED (the Fixes line closes this card).
