"""进程重启后的归档恢复集成测试。
|
||
|
||
场景：某次手术结束后写库失败 → ArchivePersister 将明细写入 durable fallback 目录。
|
||
之后 API 进程重启（相当于重新 ``create_app()``）时，``AppContainer.start()`` 会调用
|
||
``camera_session_manager.start_archive_retry_loop()`` → ``recover_from_durable_fallback()``，
|
||
把磁盘上的待落库归档读回内存；随后走真实 DB 写入路径将其成功持久化。
