New API Service Scaffolding

Create a new ConnectRPC API service for OpenMANETd following established patterns.

Arguments

• $ARGUMENTS contains the service name

Steps

1. Create proto definition in proto/openmanet/<service>/v1/:

   • <service>_service.proto with service and RPC definitions
   • <service>.proto for shared message types
   • Follow naming conventions from .claude/rules/api-design.md (Get/List/Set/Update/Execute/Stream verbs)
   • Use buf.validate annotations for field validation
   • Use google.protobuf.Empty for RPCs with no meaningful request/response

2. Generate code: Run make buf to generate Go stubs in internal/api/ and JS clients in frontend/src/gen/

3. Create handler at internal/openmanet/server/handlers/<service>.go:

   • Struct with Log zerolog.Logger + injected dependencies (interfaces, not concrete types)
   • Implement the generated handler interface
   • Use connect.NewError() with correct codes (see .claude/rules/api-design.md)
   • Log before returning errors
   • Add overrideable function fields for I/O operations

4. Register in server at internal/openmanet/server/server.go:

   • Add api.Handle(...) call with the handler struct literal
   • Include connect.WithInterceptors(validateInterceptor)

5. Wire dependencies in internal/openmanet/openmanet.go if needed

6. Create tests:

   • Unit tests in internal/openmanet/server/handlers/<service>_test.go (package handlers_test)
   • Add fakes to mocks_test.go following the fake<Interface> pattern with mutex-protected state
   • Use newTestDB(t) for database, zerolog.Nop() for logger
   • Add integration test cases in integration_test.go
   • Add proto validation tests if using buf.validate annotations

7. Verify: Run make test and make lint-go to confirm everything compiles and passes
