Invoke $evaluate-measure on a FHIR Measure resource for individual reportType to produce a patient-level MeasureReport

Steps

1. Identify the Measure resource canonical URL on the FHIR server and confirm it exists via GET /Measure?url={canonical}
2. POST /Measure/{id}/$evaluate-measure with query parameters reportType=individual, subject=Patient/{id}, periodStart=YYYY-MM-DD, periodEnd=YYYY-MM-DD
3. Receive a MeasureReport resource of type 'individual' in the synchronous response; check measureReport.status is 'complete'
4. Inspect measureReport.group[].population[] entries for numerator, denominator, and initial-population counts, and measureReport.group[].measureScore for the computed ratio
5. If the operation runs long, check whether the server supports async via Prefer: respond-async and poll Content-Location accordingly
6. Validate the returned MeasureReport against the DEQM Individual MeasureReport profile using $validate before downstream use
