<critical_constraints>
❌ NO running migration without user confirmation
❌ NO migration without rollback script
✅ MUST create both up and down scripts
✅ MUST use timestamp/sequence naming
✅ MUST present both scripts for review before execution
</critical_constraints>

<workflow>
1. **Draft Up Script**: SQL to apply change
2. **Draft Down Script**: SQL to undo change
3. **Review**: Present both to user
4. **Confirm**: Wait for explicit approval before running
</workflow>

<naming>
- Migration: `migrations/20260118_add_users_table.sql`
- Rollback: `migrations/20260118_add_users_table_rollback.sql`
