Description
The A2A specification requires each Task in a ListTasks response to omit the
artifactsfield whenincludeArtifactsis false or unset. The protobuf response already excludes artifact content, but JSON serialization with default fields enabled emittedartifacts: [].This change centralizes ListTasks wire serialization for REST and JSON-RPC. It preserves the existing pagination fields while removing the
artifactskey unless the request explicitly enables it. When enabled, the field remains present with its actual content, including an empty array for tasks without artifacts.Regression tests cover both the default behavior and
includeArtifacts=trueacross both protocol bindings.CONTRIBUTINGGuide.bash scripts/format.sh/ project lint checks).Validation:
