Non-negotiable rules:

1. Read references/stack.md first to understand the project's NestJS version, ORM, and locked decisions.
2. Then load only the references needed for the actual task.
3. One module per domain — controllers, services, DTOs, and entities live together in their module directory.
4. Controllers are thin — validate (DTO + pipe), delegate (service), return. No business logic.
5. All input validated via DTOs — class-validator decorators on every DTO, ValidationPipe globally.
6. Dependency injection everywhere — never new Service(). Inject via constructor, provide via module.
7. No circular dependencies — use forwardRef() only as a last resort, prefer restructuring.
8. Keep the heavy NestJS guidance in references/, not inline here.
