When scaffolding a gRPC service codebase according to standard conventions, where should RPC method handlers and interceptors be located in the file hierarchy?
| Checked | Without skill | With skill |
|---|---|---|
| Places RPC handlers in src/services/ directory. | Missed | Passed |
| Places interceptors in src/interceptors/ directory. | Missed | Passed |

Generate gRPC service definitions, client/server stubs, and implementations from Protocol Buffer (protobuf) .proto files. Scaffold unary, server-streaming, client-streaming, and bidirectional-streaming RPC methods with proper error status codes, interceptors for auth/logging, and health check service registration.
