description: >-
  Versioning, deprecation and operational-transparency posture for the Diebian AI
  super-resolution API. DERIVED from the contract plus probes; the provider publishes
  no versioning policy, no deprecation policy, no SLA and no status page.
api: Diebian AI Super-Resolution API
versioning:
  scheme: none-in-path
  current_version: 3.0.0
  version_source: info.version, corroborated by GET /api/auth/health
  policy_published: false
  note: >-
    No version segment appears in any of the 58 paths. A client cannot pin a version,
    so any breaking change ships to every caller at once.
deprecation:
  policy_published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  deprecated_operations: []
  deprecated_operation_count: 0
  note: >-
    No operation in the contract carries `deprecated: true`, and no deprecation or
    sunset policy is published anywhere.
status_page:
  published: false
  url: null
  note: >-
    No status page was found on any 4K Garden or fly4k host. The API does expose
    GET /api/auth/health (operationId healthUsingGET), which answered 200 with
    {"status":"ok","version":"3.0.0"} anonymously on 2026-09-05 - a health probe is not
    a status page, but it is the only availability signal a consumer has.
  health_endpoint: 'https://video-cn.fly4k.com/api/auth/health'
  health_probed_status: 200
sla:
  published: false
environments:
- name: production
  host: video-cn.fly4k.com
  note: The host the production web application calls; named in servers[] as www.fly4k.com.
- name: test
  host: tst-fly4k.4kgarden.com
  note: >-
    Serves an identical copy of the contract with servers[] rewritten to its own host.
    This is not an advertised sandbox - it is an internal test environment that happens
    to be publicly reachable. It is recorded here as an environment observation, not as
    a supported sandbox.
gaps:
- No status page.
- No deprecation or sunset policy.
