skills(pm-dispatch): name the widening-tell gate in the landing pre-check

[os-musk]

Fixes #16448

The governed half of the card. The gate itself is in
#16604 (Part of #16448,
ordinary queue landing); this PR is the one line
.claude/skills/pm-dispatch/references/contract-review.md owes it, and it
takes the human-merge route because .claude/** is a governed surface —
node scripts/pm/check-governed-merges.mjs --test over this file returns
exit 3, .claude/** x1.

The diff, in full

-- 该命令 0 = 双肢可读且一致,4 = 不一致,3 = 环境答不了;⛔ 3 不作干净。
+- 该命令 0 = 双肢一致且无放宽 tell,4 = 任一不成立,3 = 环境答不了;⛔ 3 不作干净。
+- 放宽 tell 由 `scripts/pm/check-widening-tells.mjs` 判,`no` 撞新键/成员/导出/登记即拒,附 file:line。
-- ⛔ 不与席内复核抢同一载体的放行动作;资格与档位硬门对审计者同样成立。

Two lines in, two out. The file stays at 60 lines against a 60-line ceiling
and every line stays inside the 120-byte budget (the new line is 118 bytes, the
corrected one 107).

How the added line was paid for

⛔ Not by folding two lines into one — a re-wrap that buys a line for new content
is not currency at this ratchet. It was paid by deleting a restatement,
measured rather than judged:

• its first clause, ⛔ 不与席内复核抢同一载体的放行动作, is carried verbatim
  by references/lanes/director.md:31 — the file the seat that runs the external
  audit chain actually reads, which is where the rule belongs;
• its second clause, 资格与档位硬门对审计者同样成立, is entailed by the two
  下降保险丝 lines already below it (席内复核与审计每场前必读一次服役档 and
  读数 ≠ CONTRACT_REVIEW_TIER ⇒ 该席 ⛔ 不自判清标) together with the
  Implemented-by: / Reviewed-by: SELF-REVIEW rule in the same section.

No rule leaves the tree; one duplicate does.

Measured

• node scripts/pm/check-skill-line-ratchet.mjs --self-test — 0; live run —
  0, contract-review.md is 60 lines (ceiling 60; headroom 0).
• node scripts/pm/check-skill-id-lint.mjs — 0 (the new line cites no card
  number).
• node scripts/check-nul-bytes.mjs --self-test and the live run — 0;
  control-character self-scan over the file — clean.
• node scripts/pm/check-governed-merges.mjs --test on this file — exit 3,
  as it must be.
• git merge-tree --write-tree --name-only origin/main HEAD — exit 0, clean
  against ac9376a7. No open PR touches this file (checked over the 20 open PRs
  by fetching each pm-dispatch-adjacent branch and diffing it against
  origin/main; the two neighbours edit SKILL.md, core-rules.md and
  check-half-states.mjs).

维护者速读(草稿)

改了什么 — 落地前检的第 2 条(逐对机读 check-clause2-carriers --pair)多了一句:
那条命令现在还会看 PR 的 diff,认领写 Clause-②: no 却往 schema 加键、往枚举加成员、
往已发布导出清单加行、往 registry 加登记,就拒绝并给出 file:line。同时把讲退出码的
那句改准(4 不再只是「双载体不一致」)。删掉一句与 lanes/director.md 逐字重复的复述。

为什么改 — #16349 把条款②改成方向性的(放宽才触发契约复审,收窄不触发),
维护者当时给的条件是:方向声明必须变成可检查的,而不是被信任的。在这句话落地之前,
一个 dev 只要写 Clause-②: no 就能自己把档位调低,没有任何东西读它的 diff。
现在有了,而这份文件是席位读到它的地方。

风险与代价(含回滚) — 风险是误报:一条读起来像加键的行会被拦下,作者得改申报或
在认领里解释一句。这是卡片明确接受的代价(漏报才是裁决接受的成本)。
代价是每个 no 对多花一次 GitHub 请求,只在 --pair 上花,巡检不花。
回滚:revert 本 PR 即可,--pair 的 C5 行仍在但席位手册不再点名它;要整体回滚就连
PR #16604 一起 revert,两者互不依赖。

席位意见 — (留空,待席位定稿)

你要做的 — 只有一件:确认这句话该不该进席位手册。代码那半在 PR #16604,走队列;
这半是受管面,⛔ 不翻 ready、⛔ 不入队,等你人工合并。合并顺序建议 #16604 在先——
本 PR 点名的脚本由它带来。

• 改了什么:contract-review.md 一个文件,一句改准、一句新增、一句删除,60 → 60 行不变。① 落地前检第 ② 条讲 check-clause2-carriers --pair 退出码的那句,「0 = 双肢可读且一致,4 = 不一致」改成「0 = 双肢一致且无放宽 tell,4 = 任一不成立」。② 其下新增一行:放宽 tell 由 scripts/pm/check-widening-tells.mjs 判,认领写 Clause-②: no 却往 schema 加键、往枚举加成员、往已发布导出清单加行、往 registry 加登记,就拒绝并给 file:line。③ 为付②那一行,删掉本节末尾一句复述(「⛔ 不与席内复核抢同一载体的放行动作;资格与档位硬门对审计者同样成立」)。
• 为什么改:[Decision] Clause-② — is it directional? Two seats read the same sentence oppositely, and the enqueue gate hangs on the answer #16349 把条款②改成方向性(放宽才触发契约复审,收窄不触发),你当时给的条件是方向声明必须可检查而不是被信任。代码半边在 PR pm gates: refuse a widening diff whose claim declares Clause-②: no (the mechanical half of the directional ruling) #16604(新门禁 + --pair 的第 C5 行);这一句是席位手册点名它的地方,没有它席位不知道 --pair 现在还会读 diff。
• 风险与代价(含回滚):纯规则文本,零脚本、零契约、零发布(skip-changeset)。代价是删了一句复述:前半句在 lanes/director.md:31 逐字幸存(席位亲 grep origin/main);后半句「资格与档位硬门对审计者同样成立」由同文件降档保险丝首句(「席内复核与审计每场前必读一次服役档」)和 Implemented-by:/Reviewed-by: 独立性对承接。回滚 = revert 一个 commit;本 PR 与 pm gates: refuse a widening diff whose claim declares Clause-②: no (the mechanical half of the directional ruling) #16604 互不依赖。
• 席位意见:席位逐行读了 4 行 diff,在 head cf9e808b 上重数 60 行、无行超 120 字节、零 issue 编号,ratchet 与 check-governed-merges --test(exit 3,受管)亲跑,对 origin/main eda6a60b 的 merge-tree 干净,与 pm gates: refuse a widening diff whose claim declares Clause-②: no (the mechanical half of the directional ruling) #16604 分支互相 merge-tree 亦干净。一处保留意见不阻塞:改准的那句仍未列退出码 2(读不全 = UNJUDGED),原句也没列,「⛔ 3 不作干净」的读法同样覆盖 2。CI 28 项 12:2xZ 无红,四项在跑。建议合并;顺序 pm gates: refuse a widening diff whose claim declares Clause-②: no (the mechanical half of the directional ruling) #16604 先——它带来被点名的脚本,该 PR 在席位复核里有一轮补丁,走队列落地。
• 你要做的:确认「放宽 tell 撞 no 即拒」该进席位手册,然后人工合并本 draft PR(受管面不进合并队列);建议等 pm gates: refuse a widening diff whose claim declares Clause-②: no (the mechanical half of the directional ruling) #16604 入队落地后再合。
