技能卡：条款②入队闸门——契约面 diff 复核与 needs:contract-review 复审链

[os-zhuang]

背景（事故驱动）

• objectstack#9173 往 packages/spec/src/api/error-code-ledger.zod.ts 新增错误码并令 hydrateOverlayIntoRegistry 由接受转拒绝——按条款②（维护者 2026-08-12：凡改变契约接受/拒绝行为或扩大公开面的卡一律 claude-fable-5）须按该档派发，实际按低档派发。派发席自报，维护者转达至 skills 席。
• 同日 feat(spec): register the dispatcher conformance gate's reported error codes in ERROR_CODE_LEDGER #9170（+7 码）/feat(spec): register the 9 unregistered REST wire codes the #8885 sweep found; pin the ADR-0106 D6 tier-3 emission #9177（+9 码）在同一契约面（同一 ledger 文件）的加宽改动已合并——同一漏洞一日三穿。
• 结构成因：dispatch-gates.mjs --tier 只推导条款①（路径可推导）；条款②依赖派发席在派发时刻做内容判断，无机器兜底。工具输出已诚实声明此限制。本卡不试图机器化内容判断，而是把强制关卡挪到入队前按 diff 判定——diff 是事实，卡片语义是预测。

规则包（维护者已批，2026-08-16 会话）

1. 入队闸门（SKILL.md）：PR 实际 diff 触及契约面（packages/spec/src/**，含 error-code-ledger、*.zod.ts 契约 schema）且派发档位低于契约复审档位 ⇒ ⛔ 禁止入队。派发席职责止于：卡上记一行认定、挂 needs:contract-review、停手；⛔ 禁止自查放行。
2. 资格双条件：复审席必须同时满足 ① 跑在契约复审档位；② 非该卡派发席。犯规席在结构上无资格补救自己的犯规。
3. 复审归属：常设 = 统一分诊席（Routine 模型由维护者在 Routines UI 钉在契约复审档位）；分诊轮新增子轮清 needs:contract-review——只审契约增量 diff，结论一行写在卡上，清标签后卡方可入队。每小时一轮即天然攒批。过渡期（分诊 Routine 未建成前）由 skills 席代行。
4. 降档保险丝：分诊轮开场自检当前模型，非契约复审档位 ⇒ 该子轮整体跳过、标签原样留置。卡在队列外等待是安全态；契约复审⛔不适用配额豁免降档——它的存在意义就是补偿一次低于地板的派发。
5. 档位单一来源：标签语义命名 needs:contract-review（命名审的对象，不含模型名——维护者指出：标签硬编码模型名，模型升级即全量标签迁移）；档位仅在 dispatch-gates.mjs 定义常量 CONTRACT_REVIEW_TIER（现值 claude-fable-5），SKILL.md 行文写「契约复审档位以 dispatch-gates 常量为准」。模型升级 = 改一行一个文件。
6. 派发时提示（dispatch-gates.mjs）：新增 SUSPECT_TIER_GLOBS（packages/spec/src/**），--tier 命中时输出「条款②嫌疑面：尽力从卡片内容判档；无论派什么档，入队前按 diff 过闸门」。措辞明确是提示不是裁定。

实施面

• .claude/skills/pm-dispatch/SKILL.md：入队闸门 + 复审链（上 1–5 条）。行数在现天花板内（当前 682），不提顶。
• scripts/pm/dispatch-gates.mjs：SUSPECT_TIER_GLOBS + CONTRACT_REVIEW_TIER 常量 + --tier 输出行 + 自测（嫌疑命中 / 不命中 / 输出措辞三向覆盖）。
• references/dispatch-runbook.md：视需要补一行闸门操作序（可选）。

排序与档位

• 同文件硬串行：排 objectstack#9148、Landing references: pre-enqueue mergeable_state reading + the zero-enqueued-events triage ladder — a dirty PR read as "queue refuses me" cost a lane a stall #9178 之后执行。
• 本卡开发档位：条款①路径强制（.claude/skills/pm-dispatch/**）。
• ADR 类终局三步：PR 挂起等维护者手工合并。

授权链（维护者原话）

• 「分诊 Routine 钉 fable 是没问题的」
• 「目前是 Fable，除非你有更好的方案」
• 「needs:fable-review 这个标签不好，下次模型升级怎么办」（→ 第 5 条：标签改名 + 常量单源）

PM 复核 — ACCEPT · awaiting a human merge

PR: #9197（draft，ADR 类，⛔ 不 ready/queue/auto-merge，挂起等维护者手工合并）。终 commit ad089549c，gate 全绿（ratchet 681/682 · id-lint 9 文件 · dispatch-gates 自测 234=219+15 · frame-sync · doc-authoring · formula · nul-bytes）。

逐项核定（fable 档逐行 diff）：

1. 规则包 1–5 条在 SKILL.md「入队与落地」原则区两条 bullet 落齐，另在档位条款②句尾加零行成本指针。行文关键点全部兑现：⛔ 正文与标签不写模型名，档位以 CONTRACT_REVIEW_TIER 常量为单源；needs:contract-review 恒英文；派发席「记认定、挂标签、停手、⛔ 自查放行」；资格双条件；分诊子轮 + skills 席过渡；降档保险丝 + ⛔ 豁免降档（附「豁免的对象是派发」的理由句）。
2. dispatch-gates:常量 + SUSPECT_TIER_GLOBS + 提示行只在命中时打印且与恒印的条款②地板句拼写分离（沉默≠放行的既有约束保持）；deriveTier/tierLines 向后兼容（无 suspects 字段仍可渲染，有自测钉）。watch-hint 副作用如实测量并同步 check-dispatch-gates 头注（仅注释）。
3. 面外两文件偏差均属实并接受：check-dispatch-gates.mjs 头注刷新（本改动使旧测量句过时）；ensure-pm-labels.sh 播种标签（注意：live 标签对象尚未创建，合并后首次跑该脚本时生成；过渡期首次挂标签前由本席核验/创建）。
4. runbook 略去成立：223/223 无余量，SKILL.md bullet 已含完整操作序，复制只添同步负担。

上呈维护者一项（不阻塞合并）：本次 SKILL.md 行数以 re-wrap 自筹（7 处段尾折行并回前行，字符零增删、语义零损、⛔ 行零删除，净 682→681）。棘轮按行数计，此法合字面且本次净降；但内容量增而行数降——若您对棘轮的本意是内容体量而非行数，此筹行方式需要一条裁决。dev 主动上报未擅断，本席同判：本次接受，方式待裁。
