Start with the structured-output configuration shown in the issue and compare it with the repository's documentation for JSON schema responses. Reproduce the reported validation error if possible, then identify whether the configuration or the documentation is incorrect. Done means the supported configuration and its expected validation behavior are clearly documented.
