Implement Data Access Layer

Implement the data access layer including contracts, repositories, and BLoC/Cubit for business logic.

Relevant knowledge

• For details about CQRS and contracts, see ../flutter-cqrs-usage/references/cqrs-data-access.md.
• For command/query/operation naming, base classes, the cqrs.run/cqrs.get API, repository boundaries, and contract generation, see reference.md (alongside this skill).
• For base-cubit recipes, use flutter-cubit-utils.

Steps

1. Find the required contracts in contracts.dart. Match them against the user prompt.
2. If contracts are missing, ask the user to run the contracts generator or run it manually.
3. For simple API calls, use contracts directly in the BLoC/Cubit.
4. For complex logic (caching, multiple sources, mapping), implement a repository.
5. Implement the BLoC or Cubit to handle the feature's business logic.
6. Do not create operations unless explicitly requested.
