  Versioning and evolution posture for the EMIS Partner API. No public status
  page, no formal deprecation/sunset policy, and no published SLA were found on
  the partner portal at review time, so StatusPage / Deprecation pointers are not
  emitted (absence is recorded, not fabricated).
versioning:
  scheme: uri-path
  current: v1
  spec_version: '1.2'
  docs: https://docs.partner.emis-x.uk/using-the-partner-api
  strategy: >-
    Additive; new response shapes ship as parallel V2 / Ex operations rather than
    a new URI version. EMIS is concurrently migrating the underlying platform from
    EMIS Web to the cloud-first EMIS-X.

  from: EMIS Web
  to: EMIS-X (cloud-first)
  note: FHIR resource support is documented on the portal as upcoming.
