docs(pm): the ui lane names the objectui label/assignee write channel

[claude]

Fixes #18120

Under lock 1 an objectui session cannot write a label or an assignee through MCP issue_write (its .claude/settings.json on origin/main denies the tool), and nothing an objectui seat reads said what to use instead: .claude/skills/pm-dispatch/references/lanes/ui.md carried no label line at all. The channel already exists and already takes the repository — the objectstack checkout's scripts/pm/label-write.mjs --repo owner/name, with the four steps and the read-back built in — so this card is one rule line in the lane register, not a mechanism.

The rule line — lanes/ui.md :23, 118 bytes (cap 120)

- 本仓标签/assignee 写走 objectstack `label-write.mjs --repo`,⛔ 不 MCP `issue_write`;被拒转有通道席。

It sits next to :22 「scripts/pm/** 单写手恒在 objectstack 侧 ⇒ 本席的工具需求走上游卡带 Blocked-by: 回链。」 — the channel is that objectstack-side single writer. It deliberately does not restate references/rest-channel.md :38–:39, which already carry the four steps, the read-back and the prohibition for objectstack cards:

- 标签/assignee 写恒经 `scripts/pm/label-write.mjs`:四步内建、回读、回退整组 PATCH 回传 assignees。
- ⛔ 永不 MCP `issue_write`(锁 1 已拒);会话分类器拒改动 ⇒ 无通道,交有通道席位立卡。

What is new here is the cross-repository half — --repo — plus the hand-off when a session's classifier refuses the write.

Line budget — net 0, paid by a deletion, not by a re-wrap

lanes/ui.md is pinned at 38 lines with zero headroom (check:pm-skill-ratchet). Payment is the deletion of :15 「症状位置不改流向,docs 随所记录的面走,两条同上节,⛔ 不在此另抄。」 — a pointer-only line that says as much itself.

Where the deleted rule survives: .claude/skills/pm-dispatch/SKILL.md :198, inside 〈多仓协调〉 (heading at :185) — 「其余(发布库与 apps)归 domain:ui 执行席;症状位置不改流向,docs 随所记录的面走。」 The lane file already points at that section from :3 and from :13, so the rule stays reachable for the seat that reads the lane. No ceiling raised, no line re-wrapped, no other file touched.

Acceptance — both directions, measured on bb9e97d3f

• git grep -c label-write -- .claude/skills/pm-dispatch/references/lanes/ui.md → 1 (0 before the edit); the literal control 「单写手」 still hits, now at :22.
• wc -l → 38 lines, unchanged; the ratchet prints ✓ check-skill-line-ratchet: .claude/skills/pm-dispatch/references/lanes/ui.md is 38 lines (ceiling 38; headroom 0).
• LC_ALL=C awk 'length($0)>120' over the file prints nothing; the new line measures 118 bytes.
• git diff --name-only a90a9f267..HEAD prints exactly one path — so references/rest-channel.md is untouched, and no permissions.allow text is added anywhere.
• objectui AGENTS.md is untouched by construction: that file lives in the sibling repository and is not in this diff's repo at all.
• grep -naP control-byte self-scan over the edited file: no hits (check:nul-bytes green over 8,652 files).

Gates — derived, run in the foreground, reconciled

node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack derived 15 families from the working-tree change set; all 15 ran with the exit code captured before any pipe, and all exited 0:

✓ dispatch-gates --ran: 15 derived famil(ies) accounted for — 15 run, 0 NOT-MEASURED
  (a DERIVED zero — all 15 recorded an exit code and none of them is 3).

Named in the dispatch and green here: check:pm-skill-ratchet, check:pm-skill-id-lint (27 files clean), check:nul-bytes, check:skill-frame-sync, check:pm-governed-merges, plus check:pm-governed-prose (not in the derived set — it scores silent as an artifact roster — run anyway: 2 instruction surfaces name all 5 registered governed surfaces).

Six of the fifteen first exited 3 PREREQUISITE NOT MET on a fresh worktree (node_modules absent; one also needed @objectstack/formula + @objectstack/lint built). That is not a verdict: pnpm install, then the build under scripts/pm/os-verify-lock.sh (VERDICT command-exit 0 · held the lock 2s · waited 0s), then a re-run — all 0.

Changeset

skip-changeset label, applied through the additive endpoint and read back. .claude/** publishes nothing: no package files[] ships it, and the fast-track list names .claude/** directly.

Deviation from the dispatch's suggested route

The suggested wording measured 171 bytes against the 120-byte cap, so it could not land as written; the shipped line is a compressed spelling of the same three clauses (channel + --repo, ⛔ MCP issue_write, hand-off on refusal). The suggested payment (dropping :15) measured correct and is what was used.

维护者速读(草稿)

改了什么 — objectui 车道岗位说明加一行:objectui 卡的标签/assignee 写,走 objectstack 检出里的 label-write.mjs --repo,不走 MCP;会话被拒就把卡交给有通道的席位。同一文件删掉一行纯指针句(它的两条规则逐字住在 SKILL.md 〈多仓协调〉:198),行数 38 不变。

为什么改 — 锁 1 已在两仓落地,objectui 会话的 MCP 写标签能力被拒。通道是有的(objectstack 侧那一个脚本,已在 objectui 卡上实跑过),但 objectui 席位读的文件没有一处写着它。席位找不到通道时会把状态记在散文里,而不是记在标签上——这正是同一失败形态在第二个仓的复发。

风险与代价(含回滚) — 风险低:纯指令面一行,无代码、无发布物。代价是删掉的那行指针句;它的规则在 SKILL.md 仍在,车道文件 :3 与 :13 都指向该节。回滚 = revert 本 PR 一次提交,文件回到 38 行原样。

席位意见 — (待席位定稿)

你要做的 — 读一下新增那行的措辞是否符合你的口径(尤其「被拒转有通道席」这半句),然后人工合并:本 PR 触 .claude/**,属受管面,只能由你手工落地。另:objectui 会话真正键入的那条命令要不要进 permissions.allow(前缀拼写在 objectui 会话里不一样),仍等你的裁决,本卡按 out of scope 处理。

• Served-tier: 2274/2274 CONTRACT_REVIEW_TIER — harness model stamp counted over this seat's own transcript (non-sidechain assistant messages a model served; <synthetic> harness notices excluded) at 2026-09-14T06:26Z and compared to the constant's value outside the repository; get_session external_metadata.last_served_model read equal to the constant at 2026-09-14T00:20Z.

Contract review

Head: bb9e97d3 (PR #18145, card #18120) — reviewed at 2026-09-14T06:27Z by the skills seat at the contract-review tier. GOVERNED references tier (references/lanes/ui.md only; no rules-layer file) ⇒ this in-seat record is the landing record at the tier PR #18036 enforces: the seat readies and arms auto-merge after it; no approval is owed.

① derived judgments (seat-measured on the fetched head bb9e97d3 against merge-base a90a9f26, ⛔ not taken from the report):

1. The one line: lanes/ui.md :23 「- 本仓标签/assignee 写走 objectstack label-write.mjs --repo,⛔ 不 MCP issue_write;被拒转有通道席。」 — 118 bytes under the 120 cap, one rule, beside :22 「scripts/pm/** 单写手恒在 objectstack 侧 …」 (the channel IS that single writer); it carries the three ruled halves (the objectstack-side script with --repo; never MCP issue_write under lock 1; a refused session hands the card to a seat with the channel) and does not restate rest-channel.md :38–:39.
2. Net 0 at 38/38, paid by deleted content: :15 「症状位置不改流向,docs 随所记录的面走,两条同上节,⛔ 不在此另抄。」 is gone; both of its rules survive verbatim at SKILL.md :198 inside 〈多仓协调〉 (seat grep), the section :3 and :13 already cite — a fold, not a re-wrap; every line ≤120 B; ratchet and frame-sync exit 0 on the head (seat-run in a worktree).
3. Premises held, re-measured by the dev: no label line on a90a9f267 (controls :22 / :23 present); the script prints --repo OWNER/NAME and its four steps; objectui origin/main (e3cb476) denies mcp__github__issue_write; git log a90a9f267..origin/main -- lanes/ui.md empty. The seat's own objectui#9403 pair (05:54Z, --repo objectstack-ai/objectui, read-back match) is the live proof of the channel.
4. Gates: 15 derived / 15 run / 0 NOT-MEASURED / 0 UNRUN with exit codes recorded, plus check:pm-governed-prose exit 0; six exit-3 prerequisites cleared by install + a build under the verify lock and re-run to 0. Checks on the head at 2026-09-14T06:26Z: 15 success / 12 skipped / 2 in progress / 0 red.
5. Scope held: one file, +1/−1; rest-channel.md untouched, objectui AGENTS.md not in this repository's diff; no permissions.allow text; skip-changeset is the declaration; Clause-②: no holds — no contract path; --pair 18145 on origin/main's reader → exit 0 at 2026-09-14T06:26Z before this record; 3 REST writes, 0 MCP calls per the report.

② semver: unchanged — nothing published.

③ boundary flags: the PR body stores two footers (the create channel appended its own after a rule-line-free footer) — platform-readings :331 / :338 each state half of that combination and no row states it whole; the dev's out-of-scope note names this seat as the carrier — one row when the register is next touched (the maintainer's permissions.allow word still governs the classifier half of the channel, not this line). Nothing else.

Verdict: PASS — references tier ⇒ this seat lands: ready through POST …/pulls/18145/ccr/ready_for_review with read-back, then PUT …/ccr/auto_merge; Fixes #18120 closes the card on landing.

维护者速读(终稿)

lanes/ui.md 多一行:objectui 卡的标签/assignee 写走 objectstack 检出的 label-write.mjs --repo,⛔ 不用 MCP issue_write,会话被拒就交给有通道的席位;为守住 38 行上限删了一句只做指针的话,它指向的两条规则在 SKILL.md :198 原文都在。references 层,本席自审自落地,不需要你批。
