"""orphan-lock.py — 判定「孤儿锁」并解除（🔴 用户 2026-10-09 授权：检查会话可自解除）。
|
|||
|
|
|
|||
|
|
【这条授权改了什么】
|
|||
|
|
R9 原口径（用户 2026-09-12）：「AI 一律不得删锁、不得以持有者为由单方面接管」。
|
|||
|
|
它留下一个死局：持有者会话被强杀 ⇒ 锁永远留在盘上 ⇒ 后续任何会话抢都失败
|
|||
|
|
⇒ 目标卡死，只能等用户本人到场。
|
|||
|
|
2026-10-09 实测坐实：`contentm_agent` 一把孤儿锁把第 4 步挡住，机制空转 11 棒（约 5 小时）。
|
|||
|
|
同日用户逐字授权：
|
|||
|
|
「如果 工作区 项目机制 对应的会话异常 导致未解锁的情况下， 可以授权 检查会话自解除孤儿锁」
|
|||
|
|
⇒ R9 的**唯一例外**＝本脚本覆盖的这一个情形：**锁的持有者会话已退出、不可能再来释放**。
|
|||
|
|
|
|||
|
|
【判据（⛔ 不是"看它像不像死的"，而是查持有者的真身状态）】
|
|||
|
|
锁目录 `OWNER` 第 3 行记着 `会话：<sid>`（`handoff-guard.sh` 抢锁时写入）。
|
|||
|
|
拿 sid 去宿主库 `sessions` 表查 `status`：
|
|||
|
|
· `working` ⇒ **持有者还活着 ⇒ 不动**（R9 原样）
|
|||
|
|
· `terminated` / `error` / `archived` ⇒ 异常退出／已归档 ⇒ **可解除**
|
|||
|
|
· `completed` ⇒ 已收工；再要一道时间闸（`--idle-min`，默认 30 分钟）
|
|||
|
|
内无活动 ⇒ 可解除
|
|||
|
|
⚠️ 这道时间闸只为不掐掉「刚收工、用户随时会接着聊」的会话；但它**已经不在执行**了
|
|||
|
|
⇒ 它**也不会再来释放** ⇒ 锁同样已成孤儿。
|
|||
|
|
· 查不到该 sid／库读不到／`OWNER` 里没记 sid ⇒ **一律不动**（fail-closed）
|
|||
|
|
🔴 判据只此一份，⛔ 不靠人目测 `OWNER` 文件猜死活。
|
|||
|
|
|
|||
|
|
【用法】
|
|||
|
|
python orphan-lock.py # 判定并解除（默认执行）
|
|||
|
|
python orphan-lock.py --dry-run # 只看判定，一把锁都不动
|
|||
|
|
python orphan-lock.py --idle-min 60 # 改 `completed` 档的时间闸（分钟）
|
|||
|
|
python orphan-lock.py --locks-root <目录> # 改锁根（自测用）
|
|||
|
|
退出码：0 = 没有孤儿锁（或已全部解除）｜1 = 有锁未动（持有者活着／判不出）｜2 = 参数错
