Db::repair(path, options) — an associated function (no open database needed) that: 1. Scans the directory for .log, .ldb, and MANIFEST-* files 2. Converts each WAL to an SSTable via LogReader → Memtable → TableBuilder; archives WALs to lost/ 3. Scans each SSTable to extract smallest/largest internal keys and max_sequence 4. Writes a fresh MANIFEST-000001 placing all files at L0, then writes CURRENT 5. Corrupt records and unreadable files are logged and skipped (best-effort recovery) archive_file() helper — moves files to a lost/ subdirectory (matching LevelDB's approach). 3 tests: repair after MANIFEST deletion with flushed data, repair converting WAL-only data, error on nonexistent path.
