Outlier Oracle Health (formerly Cerner) cluster: just 2 of 2908 production endpoints share this CapabilityStatement shape, including Trinity Health Corporation. This cluster advertises 35 US Core 6.1 profiles in its CapabilityStatement. A long-tail deployment variant that integrators rarely see in vendor sandbox documentation.
A CapabilityStatement shape cluster groups production FHIR endpoints by the exact CapabilityStatement they serve at runtime. Oracle Health (formerly Cerner) publishes one reference CapabilityStatement, but production hospitals deploy several distinct shapes of it — each cluster is one of those shapes.

Oracle Health's secure-tier Patient search rejects unconstrained queries — at least one of `_id`, `identifier`, `name`, `family`, `given`, `birthdate`, `phone`, `email`, `address-postalcode`, or `-pageContext` is required Population-level patient sweeps (e.g. `Patient?_count=200` to enumerate test patients) do not work on Oracle Health's secure tier. Enumeration must instead be driven through Bulk Data Access (`$export`) or through the open tier (`fhir-open.cerner.com`), which has no such constraint. This breaks the catalog-the-sandbox pattern that works against Epic's public sandbox.

This outlier cluster has too few production endpoints for us to host a dedicated mock under /v/cluster/cerner-cluster-B/ today. The modal Oracle Health (formerly Cerner) cluster is the wire shape that most production deployments use — that's the right starting point for integration testing.
Compatible with Oracle Health's (formerly Cerner Millennium) published FHIR R4 CapabilityStatement across both host fronts: fhir-ehr.cerner.com (provider/EHR-launch tier) and fhir-myrecord.cerner.com (patient standalone-launch tier).
