Status: IN
Multi-page B-tree operations (splits, deletes) are made crash-safe by writing all modifications to the WAL before applying them to data pages.
Split atomicity requires that recovery replays only complete operations, but the WAL applies all CRC-valid entries without commit verification — partial splits can be applied
