New endpoint: $ARGUMENTS

New endpoint: $ARGUMENTS

Add the operation described in $ARGUMENTS (e.g. "search Products by name") to an existing aggregate. Follow AGENTS.md.

Steps

1. Identify the target aggregate and open its *ApplicationService, *Controller, and repo interface.
2. Application contract + service: add the method to I<Name>ApplicationService and implement it, returning Result/Result<T>, with CancellationToken ct = default.
3. Repository (only if a new query is needed): add the method to I<Name>Repository and implement it in <Name>Repository (AsNoTracking() for reads). Do not add CRUD that the generic Repository<T> already covers.
4. DTOs: add request/response DTOs in *.Application.DTO/<Name>/ if the shape is new; map via Mapster in Transversal, not inline.
5. Controller: add the thin action, route it consistently with the other endpoints, translate Result → IActionResult, keep authorization consistent.
6. Tests: extend the application + controller test classes for the new behavior.
7. Verify: dotnet build and dotnet test.

No domain change unless the operation introduces a new invariant — if it does, put it in the domain service, not the application service.
