SQLite rejects ALTER TABLE ADD COLUMN with expression defaults like
DEFAULT (unixepoch()), which Drizzle-kit generated for the imported_at
column. This broke upgrades from v3.12.x to v3.13.0 (#228, #229).
Changes:
- Rewrite migration 0009 using table-recreation pattern (CREATE, INSERT
SELECT, DROP, RENAME) instead of ALTER TABLE
- Add migration validation script with SQLite-specific lint rules that
catch known invalid patterns before they ship
- Add upgrade-path testing with seeded data and verification fixtures
- Add runtime repair for users whose migration record may be stale
- Add explicit migration validation step to CI workflow
