Directory: atomic updates (tmp+rename), header CRC
Operations

Read-only readers (Db::open_ro): shared lock, no replay, no meta changes
check/repair: CRC/IO scan, overflow orphan reporting, --strict mode for CI; conservative orphan freeing
Metrics + CLI commands (metrics, metrics-reset)
WAL group-commit (fsync coalescing), P1_DATA_FSYNC option, optional page cache
CDC

wal-tail (JSONL), wal-ship (binary), wal-apply (idempotent apply with LSN-gating)
