Status: OUT
Crash recovery is simultaneously broken and unverified: no storage engine has a safe crash recovery path (non-atomic compaction, batch-blind replay, metadata-excluding CRC), and crash/failure paths are systematically excluded from the test suite — recovery bugs will persist indefinitely because neither the broken mechanisms nor their absence is tested.
A depth-2 conclusion (recovery is unsafe) combined with a depth-1 conclusion (testing excludes crash paths) creates a self-reinforcing deficiency: the bugs exist and the tests cannot find them
