name: Carefluence Open API lifecycle
description: >-
  Carefluence versions its API by FHIR release, not by date or header. The
  current line is Open API R4 (FHIR 4.0.1), served under a /r4 path segment;
  the superseded line is Open API Version 1.0 (DSTU2-era), whose documentation
  page is still live.
versioning:
  scheme: path-segment, keyed to the FHIR release
  current: R4
  current_path: /r4
  current_fhir_version: 4.0.1
  evidence: >-
    Service base https://classic.carefluence.com/r4/ is what the server's own
    CapabilityStatement declares as implementation.url.

  note: >-
    No deprecation or sunset policy is published, and the CapabilityStatement
    marks nothing deprecated. The DSTU2-era Version 1.0 documentation is still
    served with no end-of-life notice, which is the concrete gap here.
