Clean architecture

Hybrid

Domain, application, and infrastructure stay horizontal. The notes endpoint and its wire mapper are the feature slice.

clean-architectureserverpodhybrid

Hybrid keeps the inner rings horizontal and slices the outer edge by feature. domain/notes, application/notes, and infra/notes match the layer-first tree. presentation/notes/ holds the endpoint and the wire mapper together. There is no shared presentation/mappers/wire_mappers.dart.

app/ is still the only wiring site. A use case does not move into presentation/notes/ just because the endpoint lives there. If it does, the workflow has started to depend on the edge.

The package is examples/serverpod/hybrid. From that directory, dart test runs the domain test, the use-case test with a fake repository, and one integration test through the endpoint.
