MISSING_MIGRATION

A snapshot file in `meta/` has no migration file beside it.

Cause

A snapshot file in meta/ has no migration file beside it.

Each snapshot in meta/ is written beside the migration it describes. This one's migration file is not there: it was deleted, or never committed.

Fix

Restore the .sql file from version control.
Or delete the orphan snapshot.

See Production migrations.

Example

✗ The snapshot `20261020_120000_add_posts.snapshot.json` exists but `20261020_120000_add_posts.sql` does not.
  Why:  A snapshot is written beside the migration it describes, and this one's migration was deleted or never committed.
  Next: Restore the .sql file from version control, or delete the orphan snapshot.
