    • Note current database state

  2. Assess Damage

    • Run pnpm db:version
    • Check migration history
    • Identify last good state

  3. Restore

    • List backups: pnpm db:backup:list
    • Choose backup (usually pre-migration)
    • Restore: pnpm db:restore <backup>
    • Verify: pnpm db:version

  4. Recover

    • Regenerate Prisma Client
    • Test application
    • Document what happened
    • Fix migration issue

📊 Monitoring Checklist
