  payload_version_field: version
  payload_version_values: [v1]
  note: >-
    The API path prefix (/v0) and the request/response `version` field (v1) disagree with each other and QC Ware
    publishes no reconciliation of the two. No dated version history, no version negotiation header, and no
    stated support window for /v0.

  deprecated_operations: []
  note: >-
    No deprecation policy page was found on qcware.com or promethium.qcware.com, no operation in the spec
    carries `deprecated: true`, and no Sunset/Deprecation response headers are declared. No `Deprecation`
    pointer is emitted in apis.yml, because there is no deprecation policy to point at.

      release 2022-05-11) and docs at qcware.readthedocs.io. forge.qcware.com did not resolve during this pass
      (curl exit 000, no HTTP status). Recorded as effectively retired; QC Ware publishes no sunset notice.
