[Decision] one lane, several execution PMs — option D, free-claim multi-seat: a second Claude Code account claims from the same domain:spec queue (protocol text in SKILL.md / core-rules / seat-post-protocol + a check-half-states H38 filter); A partition / B outlet-only kept as alternatives

Filed by the domain:skills execution PM seat, session session_01Bz6hxDBqK62NP2W1LATvnt, at the maintainer's direct request (2026-09-16, 「spec多账号并行应靠分区扩展,具体应该怎么做」). Rewritten at 2026-09-16T09:39Z on the maintainer's remark in the seat's chat 「18394 现在写的不是我们刚才讨论的方案啊,一个车道多个项目经理」: the proposal discussed and recommended is option D — free-claim multi-seat (several execution PMs on one lane); the earlier partition proposal is kept below as option A for the record. Decision card: the answer changes protocol text (governed), so it is the maintainer's; ⛔ not auto-adjudicated. The measurement comment 5694631271 stands; the 08:53Z ruling (5694758281) was withdrawn (5694774788); nothing has been dispatched on this card.

维护者速读

事情:spec 车道 pm:queue 95 张(objectstack)+ 15 张(objectui),近三天出口 9 / 9 / 3。协议现在规定「一座位一车道双射」:一个车道只能有一个 PM 账号在认领,第二个账号进不来。你要的是一个车道多个项目经理:各自认领、各自派 dev、各自复核落地,认领时不撞车。

方案 D(推荐)= 自由认领多席:同一个车道同时坐 N 个 PM 账号。每个 PM 一张座位贴([PM seat] domain:spec · seat 2),认领评论多写一行 Seat:,派发前多读一次本车道其他席在飞卡的文件面(相交就串行或让行)。不切目录、不加标签、分诊不用改任何事。ui、devx 车道拿同一份改动直接可用。

代价:一张规则层 PR —— SKILL.md 三处「双射」句、互斥读数三/四改按席号过滤、同域在飞检查一句;core-rules 一行;seat-post-protocol 一行;check-half-states.mjs H38 按席号过滤 —— 等你批一次;每账号写量仍是 batch 3,不涨。objectui 那份 check-half-states.mjs 镜像要同步一次(#18290),不同步只是巡查在 objectui 板上误报,不挡认领。

其它选项:A = 按 packages/spec/src/ 目录家族切两个分区,各一席,要分诊打分区标签,只对 spec 成立;B = 不改协议,只做出口修复(分诊在席、连续派、派发令要求发布散文附读数、语义卡 A/B 试档位)。

你要做的:回一个字。D = 本席立刻派 skills 车道 dev 改协议(约 1 小时),PR 四件套挂起等你批一次,批后第二个账号跑 /pm-dispatch spec 即可坐席;A / B 见上。

Option D — free-claim multi-seat (recommended)

Seat posts: one post per seat, titled [PM seat] domain:X · seat N (seat 1 keeps today's post); each body is single-writer with the four sections unchanged; the pm:seat index shows N rows per lane. Precedent in SKILL.md: 「车道可按仓分席(域×仓):忙时一个 domain 车道开多个按仓席位,闲时收归一席。分席各有独立座位贴与 claim 互斥;分席是名册状态,不改协议文本。」 — D changes the split axis from repo to seat number.
Mutex readings 1 / 2 (收班简报 / 开轮标记): per post, unchanged.
Mutex readings 3 / 4 (another session's Claim: on a lane card ⇒ self-exit): the claim comment gains a Seat: domain:X#N line and readings 3 / 4 filter to the same seat number. Without this every second seat self-exits on every fire — this and the in-flight check are the two lines D really changes.
Same-domain in-flight check: before each dispatch the seat reads the lane's pm:dispatched cards' claim file faces (the candidate enumeration already reads the whole lane in one listing); an intersection ⇒ serial behind that PR or yield. Replaces 「日常同域批次选择不跑全局在飞检查,同域独立性由本域批次选择保证」.
Hot-file serial queue: lives in the claims (serial behind PR #N), not on a shared post; each post's section lists only its own chains. The inherited ledger is per seat; the lane's job description stays in references/lanes/X.md.
Bijection clauses: 「一座位一车道双射:域 X 谁管、PM Y 管什么,各恰好一个答案」 (SKILL.md 全体座位的不变量), 规则 4 「一人一车道双射」, 「每个 domain:* 与 repo:* 恰一张座位贴」 (座位贴协议), core-rules 「一座位一车道双射,每域恰一 PM」 → a PM manages exactly one lane; a lane is managed by a set of seats; one post per seat.
Patrol reader: scripts/pm/check-half-states.mjs H38 (a lane Claim: newer than the post's last event ⇒ post STALE) filters by seat number; H5 / H32 need no change. objectui's mirror copy follows through [finding] objectui's half-state findings reach no reader: the board has no anchor by ruling, and its copy of check-half-states still refuses in agent containers with the conclusion #13544 disproved #18290.
Write volume: one seat = one account = batch 3; N seats = N accounts; per-account volume unchanged (the reason batch 3→5 was rejected: 「容易封号」).
Lanes: lane-agnostic. Roll-out: spec first (objectstack 95 + objectui 15 queued), then ui (objectui domain:ui 133) and devx (objectstack 63) with the same protocol text. Partition-by-directory (A) was spec-specific.
Cost: ~7 protocol lines + one H38 filter + one claim line; one rules-layer PR (four-piece, one authorized APPROVED); dev ≈ 1 h; usable the same day.

Option A — two seats by path family (kept for the record)

Labels spec:core / spec:surface set by triage from the fix's directory (core = data/ shared/ kernel/ contracts/ system/ identity/ security/ + strictness ledger + packages/spec/scripts/** and spec-bound gates; surface = ui/ automation/ ai/ api/ marketplace/ studio/ qa/ integration/); /pm-dispatch spec part:core|surface; candidate query = domain:spec ∩ spec:PART; a second seat post per partition; cross-partition cards to the primary landing directory's seat; the mutex readings filter by partition label. Cost: one governed PR + a one-hour relabel of ~96 cards + a second session; spec-only; commits-per-directory readings in comment 5694631271.

Option B — no protocol change; throughput fixes only

Triage seated; the spec seat dispatches continuously at batch 3 with p3 families folded; dispatch orders require a measured reading for every published sentence a diff changes; a tier A/B on semantic cards for two weeks. Cost: zero protocol text. Ceiling: one account's review time and write budget. (Compatible with D; the dispatch-order line is free and can be done regardless.)

Governing text (read on `origin/main` at 2026-09-16T09:05Z)

SKILL.md :101 「一座位一车道双射:域 X 谁管、PM Y 管什么,各恰好一个答案。」 · :220 「规则 4:纵向拆分,一个分诊 PM + N 个执行 PM,一人一车道双射。」 · :255 「座位在编情况以 label:pm:seat 索引为准,每个 domain:* 与 repo:* 恰一张座位贴。」
core-rules.md :27 「…一座位一车道双射,每域恰一 PM;…」
SKILL.md 多仓协调「车道可按仓分席(域×仓)…分席各有独立座位贴与 claim 互斥;分席是名册状态,不改协议文本。」 — the precedent D generalises.
SKILL.md 入口与角色, 开轮互斥 readings 三/四 (「本车道 pm:dispatched ∪ pm:queue 卡最新非本 session 的 Claim: 评论」, 「state=CLOSED … 第一张卡的 Claim: session ID」) — the two readings D scopes to the seat.
SKILL.md 域车道「日常同域批次选择不跑全局在飞检查,同域独立性由本域批次选择保证。」 — the line D replaces.

四棱(对 D)

实际业务需求 — 实测:spec 12 天净增 34 张、近三天出口 9 / 9 / 3;ui 133、devx 63 同样积压。瓶颈是「一车道一账号」的写额度与复核时间,不是卡不够独立。
项目长远合理性 — D 与既有「分席」先例同构,只换分席轴;不加标签、不加跟踪器、不改分诊;A 只对 spec 成立,ui/devx 还要各自再切一次。
防 AI 犯错 — 撞车三道防线:认领原子写 + 回读(已有)、Seat: 行让互斥读数不误退、派发前读他席在飞文件面;H38 过滤让巡查不误报。文件面相交的卡走既有串行队,落地仍由合并队列串行。
创业阶段不扩散 — 一张 PR、零新标签、零新门禁、零新账号形态;先 spec 两席试一轮,验证 Seat: 行与 H38 后再开 ui / devx。

Premises (each with its re-check)

P1 spec pm:queue ≥ 90 in objectstack and net-positive over 12 days — re-check: GET /repos/objectstack-ai/objectstack/issues?state=open&labels=domain:spec,pm:queue&per_page=100 paged with a page=N count (control: domain:engine,pm:queue returns a small non-zero set). Read 09:0xZ: spec 95, devx 63, engine 8, cli 5, services 1, skills 8; objectui ui 133, devx 8, spec 15.
P2 the 分席 precedent exists — re-check: git grep -n '分席' origin/main -- .claude/skills/pm-dispatch/SKILL.md (control: 座位贴 hits).
P3 H38 fires on any lane claim regardless of session — re-check: h38SeatPostStale in scripts/pm/check-half-states.mjs compares the newest lane claim's instant against the post's last event (control: its H5 self-test cases).
P4 the bijection clauses sit at SKILL.md :101 / :220 / :255 and core-rules :27 — re-check: git grep -n '双射' origin/main -- .claude/skills/pm-dispatch/ (control: 座位 hits).

Dedup words: free-claim multi-seat · one lane several PMs · Seat: line claim · seat post per seat · spec partition · spec:core spec:surface

Readings for the cut (skills seat, session session_01Bz6hxDBqK62NP2W1LATvnt, 2026-09-16T08:42Z; asked by the maintainer: 「切几个合理,经常改的是哪些」).

Commits per packages/spec/src/ directory on origin/main, first-parent, 30 days (14 days in brackets), via git-history.mjs count after ensure --days=30 (window covered, floor 2026-08-10): data 134 (61) · ui 123 (54) · migrations 117 (63) · api 106 (48) · kernel 67 (36) · contracts 66 (33) · system 65 (39) · automation 41 (27) · shared 38 (16) · conversions 31 (15) · ai 23 (12) · security 17 (9) · integration 7 · identity 4 · studio 2 · marketplace 1 · qa 0; root files stack.zod.ts 27, type-alias-convention.pin.test.ts 34, index.ts 10; outside src/: packages/spec/scripts 122, packages/spec/liveness 75; the whole package 708.

Queue cards by the primary packages/spec/src/DIR their text names (95 pm:queue cards read at 2026-09-16T08:41Z; 14 name no path and 17 are tooling by keyword; 21 name more than one directory): ui 14 · api 13 · system 7 · kernel 7 · root stack.zod.ts 5 · contracts 4 · data 3 · migrations 3 · conversions 2 · automation 2 · shared 2 · ai 1.

Two consequences. (1) Commit heat and queue load differ: data is the hottest directory by commits and holds 3 queue cards — other lanes' landings touch it; the queue sits on ui and api. (2) Some files are touched from every partition — migrations/ (the ADR-0087 registry every retirement writes), the liveness/ ledger, root stack.zod.ts / index.ts / the root pin tests — a partition cannot remove them; sharding, os-regen and the merge queue arbitrate them today, and #8360 (the registry still text-merges) gains value under parallel seats.

Recommended cut — two partitions now, a third pre-registered:

partition	directories	queue today (approx.)
`spec:core`	data · shared · conversions · migrations · kernel · contracts · system · identity · security · the root files; plus the spec tooling (`packages/spec/scripts/**`, the spec gates, generators, lint rules, the liveness ledger) until the third seat exists	33 + 17
`spec:surface`	ui · api · automation · ai · marketplace · studio · qa · integration	30
(pre-registered) `spec:tooling`	the tooling half above, split off when `spec:core` reads above 45 queue cards for a week	17

Cross-partition cards (21 of 95) go to the seat of their primary landing directory; the other seat reads only. More than three partitions would need sub-directory cuts with too little load per seat under today's numbers.

Ruling recorded — skills seat, session session_01Bz6hxDBqK62NP2W1LATvnt, 2026-09-16T08:53Z. The maintainer, on the direct channel of this session (2026-09-16, after the readings comment 5694631271 was on this card), verbatim and untranslated: 「spec 同意你的建议」. The recommendation in force on this card is option A as refined by the readings comment: two seats on domain:spec partitioned by directory family — spec:core (data · shared · conversions · migrations · kernel · contracts · system · identity · security · the root files, plus the spec tooling until a third seat exists) and spec:surface (ui · api · automation · ai · marketplace · studio · qa · integration); cross-partition cards to the seat of their primary landing directory; a third cut spec:tooling pre-registered, split off when spec:core reads above 45 queue cards for a week. Governing text unchanged from the card body. Freshness gate: the newest comment on this card at recording time is 5694631271 (this seat's readings); no later comment. Same stroke: needs-user-decision → pm:queue (this card is the implementation card for the charter PR: lanes/spec.md partition section, SKILL.md entry parameter part: + partition-scoped candidate query and mutex readings + the 分席 clause, core-rules.md's 「每域恰一 PM」 re-keyed per partition, ensure-pm-labels.sh label rows); after it lands: the triage seat labels the existing queue by landing directory, a second seat post [PM seat] domain:spec @ surface is registered, and the maintainer starts the second session. Dispatch follows the claim protocol at the next free batch slot; the PR builds at CONTRACT_REVIEW_TIER (SKILL.md is a mandatory-tier path) and is rules layer ⇒ four-piece + an authorized APPROVED.

Correction — the decision is NOT made; back to the decision box — skills seat, session session_01Bz6hxDBqK62NP2W1LATvnt, 2026-09-16T08:54Z. The maintainer, on the direct channel, verbatim and untranslated: 「spec分拆没有让你开发,还是要讨论」. The ruling record 5694758281 above therefore stands withdrawn: 「spec 同意你的建议」 was not an authorization to implement, and no dev was claimed or dispatched on this card. Same stroke: pm:queue → needs-user-decision. Discussion continues on the direct channel; the card's options gain a fourth, put by the maintainer: D. free-claim multi-seat — several PM accounts on one domain:spec lane with no partition key, each claiming by the existing card-level protocol (assignee set atomically, Claim: comment, thread re-read, earlier claim wins, loser yields); the protocol text relaxes only the lane-level mutex (seat readings three / four scoped to the seat post, not the lane) and the 「一座位一车道双射」 clause (one seat per post, N posts per lane); no labels, no relabelling of the existing queue, no part: parameter; the same-file serial rule already reads every in-flight claim on the lane, so it holds across seats unchanged. Costs: occasional claim races on the top card of the total order (cheap — the atomic pair and the timestamp arbitration already handle them) and every seat reading the whole lane. The seat's view: D is the smaller text change and needs no relabel; A gives collision-free ownership and per-seat queues. Either is a governed-text change and waits for the maintainer's word.

Ruling recorded — option D (free-claim multi-seat) — skills seat, session session_01Bz6hxDBqK62NP2W1LATvnt, 2026-09-16T09:40Z.

The maintainer, in this seat's live chat, verbatim and untranslated, in order:

「18394 现在写的不是我们刚才讨论的方案啊,一个车道多个项目经理」 — after which this card's title and body were rewritten to carry option D as the proposal (2026-09-16T09:39Z, the edit above).
「你说的是这个吗D. free-claim multi-seat」 — the seat answered yes.
「我已经同意了。」

Read as the decision on this card: D. Earlier on the same thread the maintainer's 「spec 同意你的建议」 was recorded (5694758281) and withdrawn on 「spec分拆没有让你开发,还是要讨论」 (5694774788) because the card then carried the partition proposal; the agreement now names the rewritten card, so the withdrawal does not apply to it.

What the ruling authorises, no wider: one skills-lane card — this one — dispatched for the protocol text of option D as written in this body (the Seat: claim line; mutex readings 3 / 4 scoped to the seat; the same-domain in-flight check reading other seats' claim file faces; the bijection clauses rewritten to one PM ⇒ one lane, one lane ⇒ a set of seats, one post per seat; check-half-states.mjs H38 filtered by seat number with self-test cases). Rules layer (SKILL.md, references/core-rules.md, references/seat-post-protocol.md) ⇒ the PR hangs as a four-piece for an authorized APPROVED, then lands by ruling C; SKILL.md mandates the contract-review tier for the build. ⛔ Not authorised by this ruling: any domain:* split, new labels, a change to batch, or the objectui mirror of H38 (that is #18290's own question).

Same-act label write: needs-user-decision → pm:queue (one replace). Dispatch follows the lane's batch ceiling (3 / 3 in flight at this record; this card is next in the total order as p2 with a maintainer ruling).

ACCEPT — skills seat, session_01HPfcjvF23QBoBj7P47DDxs, 2026-09-16T10:41Z. Report 5696098988 · PR #18436 (draft, head a07d739f, base main, first line Fixes #18394). Ruling-ref 5695364899 (option D).

Checklist, verified against GitHub and the tree — not against the report's narrative:

Shape / scope: draft ✓ · base main ✓ · changed files = .claude/skills/pm-dispatch/SKILL.md (+10 / −10), references/core-rules.md (+3 / −3), references/seat-post-protocol.md (+2 / −1), scripts/pm/check-half-states.mjs (+103 / −13) — exactly the claimed surface ✓ · skip-changeset matches AGENTS.md's own arm ✓ · no content/docs/releases/ ✓.
Protocol text read line by line against the ruling's authorised scope (「the Seat: claim line; mutex readings 3 / 4 scoped to the seat; the same-domain in-flight check reading other seats' claim file faces; the bijection clauses rewritten to one PM ⇒ one lane, one lane ⇒ a set of seats, one post per seat; check-half-states.mjs H38 filtered by seat number with self-test cases」): readings 三/四 gain 「同席号」 ✓ · 全体座位的不变量 line → 「一 PM 恰管一车道,一车道由一组座位管,一席一贴」 ✓ · rule 4 → 「一人恰一车道,一车道可坐多席」 ✓ · seat-index clause → 「每车道一组座位贴、每席恰一张」 ✓ · the 分席 pair → the seat-number axis (· seat N, or 域×仓) + 「认领评论带 Seat: domain:X#N 行申报席号(缺省席 1);同席认领互斥,他席认领不触发自退」 ✓ · the three in-flight lines → two: 「派发前在飞检查:读本车道 pm:dispatched 卡认领评论申报的文件面,本地求交、不另发查询」 + the cross-domain scope kept as an addition, intersection ⇒ serial or yield ✓ (the line D replaces, 「日常同域批次选择不跑全局在飞检查」, is gone) · claim template gains Seat: ✓. core-rules: the four-readings digest, the bijection digest and the cross-domain digest follow their SKILL.md lines ✓. seat-post-protocol: domain:X · seat N title suffix (seat 1 keeps today's post) + seat numbering for a new post = max + 1 ✓. ⛔ Nothing outside the ruling: no domain:* split, no label, no batch change, no objectui edit ✓. Two payments accepted as deletions in place: 「分席是名册状态,不改协议文本」 (false under D) and the 「只在跨域例外路径上跑」 restriction (superseded by the same-domain check).
Code: seatLane parses · seat N before the @ repo leg (absent ⇒ 1; unparseable title ⇒ null); claimSeatNumber reads the claim's Seat: key line in the same key-line shape the file already reads for Branch: (absent ⇒ 1, present-but-unreadable ⇒ null so it matches no seat); newestLaneClaim(lane, issues, comments, seat = 1) filters rows by seat BEFORE the reused latestClaimComment (the claim predicate is neither widened nor narrowed); the H38 sentence names the seat; the single call site passes the post's seat. Default seat = 1 keeps every pre-existing call reading as before (pinned by a case). 26 new H38 seat: cases cover: suffix parses as the lane, sibling-board suffix stays foreign, absent line = seat 1, other-seat claim not counted, same-seat newer claim found, unreadable line matches nothing, newest same-seat wins over a newer other-seat claim.
Gates re-run by the seat on a detached worktree at a07d739f: check-skill-line-ratchet.mjs exit 0 (SKILL.md 812 / 812 · core-rules 151 / 151 · seat-post-protocol 91 / 91 — the one line of headroom spent) · check-skill-id-lint.mjs exit 0 (27 files clean) · check-skill-frame-sync.mjs exit 0 · check-half-states.mjs --self-test → 4296 cases pass (base 4270). Dev's --ran: 47 / 47, none NOT-MEASURED; check:doc-formula-expressions 3 → 0 after building its prerequisites (recorded, not hidden).
Writes: mcp_calls 0 · api_writes 3 REST (draft PR, one label, the report) + 3 pushes — within budget; no assignee write, no second claim, never flipped ready, no review requested by the dev.
Deviations accepted: tip commit amended BEFORE its first push (unpublished; the repo's model-free trailer pair); one gate batch pushed past the foreground cap and read back from its exit ledger; origin/main moved three commits during the run, none touching the four files.
Out-of-scope findings: three noted, not filed — the dated seatLane census comment, the H38 specimen narration, and the objectui mirror (that is [finding] objectui's half-state findings reach no reader: the board has no anchor by ruling, and its copy of check-half-states still refuses in agent containers with the conclusion #13544 disproved #18290's, by the ruling). None in the three filing classes.

Path face (check-governed-merges.mjs --test): .claude/** ×3 ⇒ GOVERNED, rules layer ⇒ terminal four-piece, ⛔ not landed by any seat: ① this comment is the review of record (contract-review tier, the build tier the ruling mandated) · ② needs-user-decision on PR #18436 + the seat's 速读终稿 as a PR comment · ③ review requested from os-zhuang and hotlong · ④ listed under awaiting a human merge in the round report. After an authorized APPROVED (GOVERNED_APPROVERS, not dismissed): ruling C — this seat lands it (record on the current head, --pair 0, all checks green or rostered skips, clear the label, ready via the CCR route, auto-merge SQUASH). Once MERGED, a second seat can sit on any lane by /pm-dispatch <domain> with a [PM seat] domain:X · seat 2 post and Seat: domain:X#2 on its claims. Card stays pm:dispatched + assignee until Fixes closes it. Hot-file: the H38 region is released at MERGED; the later lander among #18385 / #18393 / #18369 merges origin/main.

Queue build red on PR #18436 — as predicted, recorded, not re-enqueued — skills seat, session_01HPfcjvF23QBoBj7P47DDxs, 2026-09-16T11:29Z.

Reading at 2026-09-16T11:27Z: the merge-group commit for PR #18436 (9c31e270, on top of PR #18430's b6fe311a) finished 25 success / 1 failure — Lint & Repo Gates (check-run 104770166330, annotation 「Process completed with exit code 1」 at the workflow step; the notice row reads unmeasured-gate-tail: measured=no never_ran=NOT_MEASURED). The job log is not readable through this session's egress proxy (GET /actions/jobs/104770166330/logs returned 0 bytes), so the failing STEP inside the job is not confirmed from the log; the seat's pre-measured cause stands as the initial diagnosis (PR comment 5696514750): scripts/pm/check-half-states.mjs at 2,103,266 B in that merge-group tree crosses check-closing-keyword-parity's 2,097,152 B size skip and is reported as a stale registry row. The PR is still listed in the queue at this reading (gh-readonly-queue/main/pr-18436-* present, no removed_from_merge_queue event yet).

Merge-queue triage per landing-operations B: this is a new signature (no ledger entry; root cause card #18435, dispatched 11:00Z) ⇒ ⛔ not re-enqueued, ⛔ no registry row removed, ⛔ no change to this PR's diff. When #18435's fix is on origin/main the base carries it and this seat re-arms auto-merge on the same head a07d739f through the CCR route (the APPROVED 5221866521 on that head stays valid — approval is not commit-bound under ruling C). PR #18437 (#18385) waits on the same fix; PR #18444 (#18393) does not (its merged size is under the line) and is being landed now.

Ruling C — re-armed after the blocker landed — skills seat, session_01HPfcjvF23QBoBj7P47DDxs, 2026-09-16T12:18Z. PR #18449 (#18435, the parity-gate fix) merged as e4449b4e at 2026-09-16T12:16:28Z; origin/main now reads size > SIZE_CUTOFF && !REGISTERED.has(f) in scripts/check-closing-keyword-parity.mjs, so a merge group carrying scripts/pm/check-half-states.mjs above 2 MiB is READ, not skipped — the cause of PR #18436's 11:32Z dequeue is gone from the base. Ruling C readings on PR #18436 at 2026-09-16T12:18Z: os-zhuang APPROVED 5221866521 on the current head a07d739f (unchanged since) ✓ · review of record = ACCEPT 5696161167 ✓ · check-clause2-carriers.mjs --pair 18436 exit 0 (11:10Z reading; head unchanged) ✓ · CI on a07d739f converged (26 success / 15 skipped) ✓ · ready since 11:09Z (the approver's flip) ✓ · PUT …/ccr/auto_merge {"merge_method":"SQUASH"} by this seat → 200, reply {"enabled":true,"merge_method":"squash"}, added_to_merge_queue 12:18:04Z on the timeline ✓. Not done: the needs-user-decision strip on the PR — refused by this seat's harness classifier both times (10:2xZ, 11:2xZ, 「Merge Without Review」); the label does not gate the queue and stays as residue for a seat with a channel or the maintainer. Tracked to MERGED with the two readings; landing record follows here. Platform reading for the round report: the ccr/auto_merge reply carried merge_method: "squash" this time, where the fact table records the stored method always reading merge — one data point, recorded, not yet a row.

Landed — skills seat, session_01HPfcjvF23QBoBj7P47DDxs, 2026-09-16T12:41Z. PR #18436 (head a07d739f) merged by the queue as 62ab658aaa at 2026-09-16T12:37:44Z — the merged_at instant (added_to_merge_queue 12:18:04Z on the re-arm, base fcba1919; the earlier 11:10:01Z enqueue by os-zhuang was dequeued red at 11:32:02Z on the parity-gate byte hazard, root-caused and fixed by PR #18449). Two readings at 2026-09-16T12:41Z: origin/main carries (#18436) and SKILL.md :202 now reads 「车道可分席(席号 · seat N,或域×仓):忙时一车道开多席,闲时收归一席;每席独立座位贴。」; no gh-readonly-queue/main/* ref remains. Squash = single parent (fcba1919). Rules-layer governed landing under ruling C: authorized APPROVED by os-zhuang 11:09:56Z, 速读终稿 5696161767, ACCEPT 5696161167, re-arm record 5697295441 (ready state already held; PUT ccr/auto_merge SQUASH 12:18Z). This card closed by Fixes at 2026-09-16T12:37:46Z. Residue (pm:dispatched, assignee) stripped through label-write.mjs in the same stroke and read back. needs-user-decision on the PR was left in place — the classifier refused its removal (recorded 5696708762); harmless residue on a merged PR.
