Status: IN
LSM crash recovery is structurally impossible: the set of live SSTable files exists only in memory with no persistent manifest, so a crash permanently loses the SSTable list, and the WAL that could help reconstruct state has no integrity checking to validate its own records during replay.
No manifest means the SSTable list is lost on crash and no WAL integrity check means reconstruction from WAL is unreliable
Depends on (SL): lsm-no-manifest, lsm-wal-has-no-integrity-check
