Description

The new func (s *gcsService) GetArtifactVersion(ctx context.Context, req *artifact.GetArtifactVersionRequest) method does not appear to be covered by the contract tests yet.

https://github.com/google/adk-go/blob/b8eb8c5f07cf43889a02bce2eac2d104a81fb927/artifact/request_validation_test.go#L329

It would be useful for the contract tests to define which ArtifactVersion fields are required across backends, which are optional, and whether backend-specific omissions are allowed.

Contributor guide

Research direction
Examine existing contract tests in artifact/request validation test.go to understand the pattern, then add coverage for GetArtifactVersion, defining required and optional fields.
