target: &TargetEndpoint,
expectation: Option<ModelExpectation>,
timeout: Duration,
) -> ReportExpand description
2026-09-26: Read the model list, check the served model against
expectation when one is given, then ask every CHECKS question.
The first failed question request stops the questions and is stored as
Report::transport_error; nothing here returns an error.
