 ## Summary
 
-> To be filled on completion
\ No newline at end of file
+> Added GatewayDispatch::invoke_streaming() returning BoxStream<ResponseEnvelope>. Security axis provably identical to invoke() via shared build_root_context_inner(bounded: bool); extracted build_root_context_streaming for deadline: None (unbounded subscriptions). Calls OperationRegistry::invoke_streaming(). to_mcp untouched. Added 9 unit tests (all error paths + streaming dispatch + deadline: None verification). 243 tests pass.
