…urge - WAL reader now handles both row and columnar entry formats natively, eliminating the row-conversion roundtrip during recovery - Database name is stored in WAL entries via an envelope format (0x01 marker + db name), enabling correct routing on recovery - AppendRawWithMeta builds WAL entries in a single allocation to avoid copying the ~104KB payload (fixes throughput regression) - WAL files are purged on clean shutdown after buffer flush, preventing duplicate recovery on restart - Fixed _database/_measurement key mismatch in row-based WAL recovery
Partial reads during periodic recovery are expected when the active WAL file is being written concurrently. Not an error condition.
