## How to choose

- Where the records come from: Check which networks, EHRs or devices each listing reaches, since a patient whose provider or wearable is not covered returns an empty record.
- Consent and patient authorisation: Check how the patient grants access and how that consent is recorded and revoked, because an agent handling health data must act on a documented permission.
- FHIR version and resources: Check the FHIR version and the resources supported, since an agent that expects one resource shape will misread records returned in another.
- Compliance terms and access approval: Check whether a business associate agreement, a sales review or a network approval is needed before going live, as these can take weeks.

- How the benchmark tests this category: In this run, public evidence against the published checklist. When the task suites run, one synthetic patient queried through each listing's sandbox. We request records or wearable data, write an observation where the API allows it, and read it back. We check FHIR conformance, the consent step, latency and what access took.
