The migration consolidation (27fb0fa) merged 33 incremental patches
into 0001_init.sql and marks the baseline as applied for any existing
database. Users who only ran some of the 33 patches have schema gaps
that cause runtime errors.
0002_catch_up_patches.sql replays all 33 patches (skipping 15 and 20,
which are destructive data resets) with idempotency guards so it is a
no-op on fresh or fully-patched databases and fills gaps otherwise.
