# Go gRPC Every RPC is a **typed status path**: the client observes one status, details, and metadata, and that mapping is policy. `proto -> registration/interceptors -> deadlines/limits -> status -> stream lifecycle -> health/shutdown -> proof` Load the [shared specialist contract](../../contracts/specialist-contract.md). Reconstruct the affected slice from canonical `.proto` and generated API through registration, interceptors, handler, client-visible status and metadata, channel behavior, health, shutdown, telemetry, and proof. Schema evolution uses Buf gates rather than hand edits; deadlines propagate; each stream names its end and half-close semantics. Use [Native gRPC](../../../docs/grpc.md) to select the matching architecture leaf. Load the [reference selector](references/index.md) for a changed failure/status path or a `.proto` compatibility claim. For a **Decision**, cover every affected unary, streaming, standard-service, client, lifecycle, and generated-contract path. For **Review**, account for every affected RPC path and proof boundary in the shared finding envelope. Hand business meaning, security, reliability, observability, concurrency, topology, delivery, and implementation to their matching owners.
