pm-dispatch: record the triage seat's alternating-repo pickup and its 4-hour starvation guard as a lane reference (`references/lanes/triage.md`) — execution of the #15476 ruling A

[os-steve]

Filed by the domain:skills seat (session session_019RfFHiRCSs3JXLK4cwcfox, os-steve) as the documentation half of the maintainer's ruling on #15476 (batch #41, recorded by the director seat in comment 5548638091, verbatim reply 「同意」). Self-triaged: priority:p2, governed surface, pm:queue until a slot frees.

The ruling (as recorded)

The triage seat stays single. Alternating-repo pickup is standing seat discipline: one round objectstack, one round objectui, one round objectstack …; within a repo, oldest-first. Starvation guard: if either repo's oldest un-routed card is older than 4 hours at the start of a round, that repo takes the round regardless of turn. No second seat, no fire-frequency change. The ruling's execution line: "one paragraph in the triage lane reference under .claude/skills/pm-dispatch/references/lanes/".

Placement (the seat's reading — the ruling's execution note assumed a file that does not exist)

references/lanes/ carries eight lane job descriptions (cli · devx · director · engine · hotcrm · services · skills · spec) and none for the triage seat; the triage seat's standing duties live in SKILL.md's「分诊座位职责」section, which is at its ceiling (811 of 811) and already has two cards serial on it (#15666, #15404). ⇒ Create references/lanes/triage.md as the triage seat's lane reference, holding today only what the ruling asks for: the pointer line every lane file opens with (the SKILL.md section it details), then the pickup rule as rules — one rule per line, ≤120 bytes, plain Chinese with identifiers in backticks, ⛔ only on prohibitions, no dates, no quotations, no card numbers:

1. 分诊每 fire 只取一个仓,两仓轮替:objectstack、objectui、objectstack……;仓内按最旧优先。
2. 饥饿守卫:轮次开始时任一仓最旧未路由卡超过 4 小时,该仓本轮优先,不论轮到谁。
3. ⛔ 不回退到跨仓全局最旧优先;⛔ 不因积压增设第二分诊席或改 fire 频率。

Plus its CEILINGS row in scripts/pm/check-skill-line-ratchet.mjs, pinned at the landed count (headroom 0, the map's convention for a new file), and a MAX_TABLE_ROW_BYTES row at 0 (no table). ⛔ No edit to SKILL.md or any other lane file; the triage seat post (#6015) may point at the file afterwards — that is the triage seat's own edit, not this card's.

Serial and gates

The ratchet map is shared with PR #15641 (member 3 of #15379, re-merging main after being removed from the queue) on disjoint rows — this card dispatches after PR #15641 lands to keep the map's rows in one order. Gates: check:pm-skill-ratchet, check:skill-frame-sync, check:pm-skill-id-lint, check:pm-governed-prose, check:nul-bytes, whatever dispatch-gates --commands derives. Governed (.claude/**) ⇒ draft PR, in-seat review, os-zhuang + hotlong, human merge, skip-changeset. XS.

Related: #15476 (closed, the ruling) · #15379 (the rules-only programme this file is born under).

[claude]

Claim: PM loop round 7 — unblocked when PR #15641 (member 3 of the corpus programme) MERGED 15:38Z; executes the recorded ruling on the triage seat's alternating-repo pickup and its 4-hour starvation guard as a new lane reference.
Session: session_019RfFHiRCSs3JXLK4cwcfox
Branch: claude/issue-15671-triage-lane-reference
Worktree: objectstack-issue-15671
Domain: domain:skills
File surface: new .claude/skills/pm-dispatch/references/lanes/triage.md (the pointer line every lane file opens with, then the three pickup rules as rules — one per line, ≤120 bytes, no dates, no quotations, no card numbers) + its CEILINGS row (pinned at the landed count) and MAX_TABLE_ROW_BYTES row (0) in scripts/pm/check-skill-line-ratchet.mjs. ⛔ No edit to SKILL.md or any other lane file.
Container & model: XS, mode:subagent, model: opus (dispatch-gates.mjs --tier: references/** and scripts/pm/** hit no mandated glob; clause ② not engaged — no contract accept/reject change).
Clause-②: no
Serial constraints cleared: no open PR adds a file under references/lanes/ or a row to the ratchet map (#15929, in flight, edits lanes/director.md in place). GOVERNED (.claude/** in the diff) ⇒ draft PR, in-seat review, os-zhuang + hotlong, human merge, skip-changeset; at ACCEPT the seat adds needs-user-decision + the 维护者速读. The PR carries Fixes #15671.

  "summary": "Two files, as ruled. NEW `.claude/skills/pm-dispatch/references/lanes/triage.md` — 7 lines: the H1 the sibling lane files open with, the pointer line naming the SKILL.md section it details (分诊座位职责), then the three ruled rules one per line (alternating-repo pickup with oldest-first inside a repo; the 4-hour starvation guard; the two prohibitions). Nothing else in the file. `scripts/pm/check-skill-line-ratchet.mjs` gains exactly two rows: `CEILINGS` at 7 (the landed count read from the gate's own run, headroom 0, the map's new-file convention) and `MAX_TABLE_ROW_BYTES` at 0 (no table row). The diff on that file is 8 added lines, 0 removed — no other row of either map moves, and SKILL.md and the eight existing lane files are untouched. Draft PR 15958 with `Fixes` on the card as its first body line and the 维护者速读(草稿) section (五段, 席位意见 left blank); `skip-changeset` applied through the additive labels endpoint with a comparison read-back. Not flipped ready, not enqueued, no auto-merge armed, no reviewers requested — those stay with the seat.",
  "tests": "Byte widths with `LC_ALL=C awk`: widest line is line 3 (the pointer line) at 119 B against the 120 B budget; rule lines 113 / 110 / 101 B. The verbatim director.md pointer spelling with 分诊座位职责 substituted measures 122 B, so the file takes the six domain lane files' shorter tail (⛔ 不迁入本文。). Gate derivation: `node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack` (no paths passed; it derived the 2-path change set itself, 1 working-tree + 1 untracked) yielded 36 commands. All 36 were run, each exit code captured before any pipe (redirect-then-capture); reconcile: '✓ dispatch-gates --ran: 36 derived famil(ies) accounted for — 36 run, 0 NOT-MEASURED.' One of the 36 first returned exit 3 — `pnpm --filter @objectstack/lint run check:doc-formula-expressions`, PREREQUISITE NOT MET, nothing measured, not a finding; built @objectstack/formula + @objectstack/lint through the shared verify lock and re-ran it green. Named gates, all green on the final commit 32945f93f1 (re-run after committing, not before): '✓ check-skill-line-ratchet self-test: 155 cases pass.' (155 on main too — no case added or removed); '✓ check-skill-line-ratchet: .claude/skills/pm-dispatch/references/lanes/triage.md is 7 lines (ceiling 7; headroom 0).'; '✓ check-skill-line-ratchet: ... widest table row is 0 bytes (pin 0; headroom 0).'; every other ceiling line in that run unchanged. '✓ check-skill-id-lint: 25 file(s) clean (pattern /#[0-9]{3,}/g).'; check-skill-frame-sync: 'binding sentence present in all 2; 4 count mention(s) agree; 74 markdown files scanned for undeclared copies.' (the decision frame is absent from the new file, and its anti-dormancy fingerprints do not fire); '✓ check-governed-prose: 2 instruction surface(s) name all 5 registered governed surfaces ... and claim no others.'; 'check-nul-bytes: OK (scanned 7694 text file(s) ... no raw ASCII control bytes)' plus a direct control-byte grep over both edited files (no match). Whole-repo `pnpm lint` (`eslint . --no-inline-config`) green through `bash scripts/pm/os-verify-lock.sh` slot issue-15671: 'VERDICT command-exit 0 · held the lock 82s · waited 0s' (shared-box seconds, as the lock's own line states). `node scripts/pm/check-governed-merges.mjs --test` on the two paths exits 3 — GOVERNED, `.claude/**` ×1. CI on head 32945f93f16ed7dc2785b3ae8e11c0f073a397f5, polled in the foreground until every run completed: 37 check runs, 26 success, 11 skipped, 0 failures (Lint & Repo Gates success; Check Changeset success/skipped under `skip-changeset`; all five Type Check runs success). No ablation was run: this card adds prose plus two ratchet map rows, and the gate's own live line on the new file is the direct measurement.",

    {
      "question": "The new file's first two lines are a judgment inside the ruling — the ruling fixed which SKILL.md section the pointer names, not the H1 shape or the pointer's tail. Triage is a seat rather than a domain lane, so I mirrored director.md's seat form: H1 `# 席位章程:分诊席(Triage)`, and the pointer line with the six domain lane files' shorter tail (⛔ 不迁入本文。) because director's own tail (本文件) puts the line at 122 bytes, over the 120-byte cap.",
      "options": [
        "A — keep it: seat form for a seat, tail borrowed from the domain lane files so the line fits at 119 B",
        "B — H1 as `# 车道岗位说明:分诊席` (the form hotcrm.md uses for a non-domain lane), same pointer line",
        "C — keep director's tail (本文件) and buy the 3 bytes elsewhere in the pointer line"
      ],
      "recommendation": "A. It is the only spelling where both halves are verbatim from an existing sibling and the line stays inside the byte cap; B invents a third H1 shape for the same file class, and C reworks a sentence eight files already share to save nothing a reader can see."

  "out_of_scope_findings": [
    "filed as #15965: the ratchet self-test's lane roster is a hand-written list of eight names (`.every` over them), so the ninth lane file's CEILINGS row is pinned by no case — extending it also moves a label pinned in the self-test expectation table, which is outside this card's two-row scope. Proposed shape in the issue: derive the roster from the lanes/ directory.",
    "not filed — already open as #15957 (found independently by another seat at 16:24Z): the ratchet prints an unclaimed 2-byte pin tighten for spec-property-retirement/SKILL.md on every run. Pre-existing on main and untouched by this PR."
