"""协调员审计循环复审修复测试：B1 + I1 + I2 + I3。
|
||
|
||
只用 init_db 的本地库与注入的假 runner，不跑真实模型回合、
|
||
不联网。覆盖（按任务书）：
|
||
- B1：旧门拒绝审计行（早于本轮 started_at）不再误判新失败，
|
||
子任务执行失败应推回而非升级；本轮门拒绝审计行仍升级；
|
||
started_at 未知时保守保留门拒绝（fail-closed 向升级）。
|
||
- I1：merged 计完成——evaluate_outcome / build_report /
|
||
合流 pass 三处对齐；sync 不把 merged 子任务重排。
|
||
- I2：合流推回事务里父 CAS 失败时，子任务不被孤儿重排、
|
||
包列不写、且有明确审计；推回成功时父任务已由合流
|
||
CAS 回 queued（hook 不再另做父 CAS）。
|
||
- I3：推回存库分支异常时走升级而非回正常终局，error
|
||
写明存库失败、记 escalated 审计；已消耗的轮次不恢复。
