## Schema Changes (ADR-009)

- **NO TypeORM migrations** — edit SQL schema directly
- Always check `specs/03-Data-and-Storage/lcbp3-v1.8.0-schema-02-tables.sql` before writing queries
- Update Data Dictionary when changing fields

## UUID Handling

See `01-adr-019-uuid.md` for complete UUID rules.

Quick reminder:

- ❌ `parseInt(uuid)` → NEVER
- ❌ `Number(uuid)` → NEVER
- ✅ Use UUID string directly
