2026-08-04/05 夜 spec 车道以串行接力连落 10 个 PR(#5304 → #5365),六个情形是
现行 SKILL 没有覆盖、靠现场即兴的,各有实付学费。按 issue 注明的落点章节逐条插入:

- 第 7 步「入队与落地」新增平行小节「串行接力」:每棒一整圈(auto-merge 由 PM 挂、
  dev 永不碰,ready 与 auto-merge 顺序不可反且每棒各走一次)、相邻棒同文件交接语义
  而非文本(#5318/#5319 实例)、两棒散文互锁由 PM 指派分工(#5323↔#5365、#5335)。
- 「入队与落地 A」新增锚点断言措辞:authenticity = baseRev 是 origin/main 祖先 且
  keys 与该 commit 逐行一致;baseRev 允许滞后;⛔ 不得要求 baseRev == merge-base
  (那会教唆手改锚点,即 #4650 攻击自身)。四步序的第 3 步补上「先 commit merge」,
  并引用 #5370 / #5371 两个新陷阱(仅引用,不实现)。
- 第 5 步派发词 + 第 7 步 review 新增「裁决传播 = 全仓 pin 扫描」:翻 pin 一轮翻完
  且必须保留承重(#5322 裁决、#5365 的 REST 层漏翻)。
- 第 6 步 Collect 的 subagent 半边新增停摆纠偏:watcher 永不触发,中途状态即停摆
  信号,第三次视为不可靠改走接手协议。生产端半边同步落到 os-dev.md 资源纪律第 6 条。
- 第 5 步 same-day churn 新增姊妹段「飞行中范围重叠」:每轮读 origin/main 时对每个
  在飞 dispatch 做相交判断,相交即预警(#5322 × #5335 实例)。
- 「入队与落地 B」新增依赖 PR 的预期红停放:draft 停放 + 签名级预期红清单 + 解除
  条件,新签名才是真问题(#5365 的 REST 红即由此识别)。

仅改 `.claude/` 内部 agent 协议文本,不发布任何包;六条落点之外未动任何段落。
