  https://developer.workday.com/bundles/rest-directory-ui/public/static/openApiFiles/benefitPartner_v1_changeLog.json
  and .../benefitEnrollmentEventOfferings_v1_changeLog.json - the per-service change logs Workday publishes
  alongside each REST contract
scheme:
  releases: 'Workday release train, YYYY.WW (calendar year and week), e.g. 2026.33'
  api_versions: Per-service integer versions in the path (v1, v5, v7 ...)
  format: >-
    Each change log is itself an OpenAPI-shaped document whose paths are keyed release/endpoint and whose tags
    carry the release date, so a diff is machine-readable per operation.
