  note: API Evangelist model of the US Core FHIR R4 profile MEDITECH states it supports. This is NOT a MEDITECH-published OpenAPI — MEDITECH publishes none. Its authoritative reference is the Greenfield API Explorer at https://greenfield.meditech.com/explorer/topic/welcome, which is publicly reachable but client-rendered and robots-disallowed, so it cannot be fetched or crawled — reconcile this file against it by hand. The {facility} server variable reflects MEDITECH's per-customer deployment model; real service base URLs are issued per organization. Paths, parameters, and response shapes here follow the FHIR R4 standard and have not been confirmed against a live MEDITECH endpoint. Validate every operation against the target facility's CapabilityStatement (/metadata) before building on it.
