## Testing Rules

- Vitest with globals enabled (describe, it, expect — no imports needed)
- In-memory SQLite for all database tests (`:memory:`)
- Test files co-located as `__tests__/*.test.ts` or `*.test.ts`
- Use Brain class directly for integration tests (not HTTP)
- Clean up: each test should create its own Brain instance
- No mocking of SQLite — use real in-memory database
- Assert both happy path and error cases
- Test entity/relation CRUD, search, temporal queries as applicable
