Closes #7334
Problem: With
RemoteA2aAgent(use_legacy=False)on a2a-sdk 1.x, the interceptor wroteA2A-Extensionsintoclient_call_context.state['http_kwargs'], which 1.x transports never read (they build headers fromservice_parameters). The header never reached the server.Fix: On a2a-sdk 1.x, read/merge/write the header in
service_parameters(preserving other entries); the 0.3.x path is unchanged. Mirrors_add_request_headers.Test:
TestNewIntegrationExtensionInterceptor— fails without the fix (KeyError: 'A2A-Extensions'), passes with it.pytest tests/unittests/a2a: 731 passed, 49 skipped.AI assistance: drafted with Claude Code; reviewed and tested by the author.
