description: >-
  Cross-cutting standards assessment for the Diebian AI super-resolution API, DERIVED
  from the published contract and from anonymous probes. Every entry carries the
  evidence it was judged on. No compliance certification or trust programme was found
  published by this company, so no Compliance pointer is emitted.
api: Diebian AI Super-Resolution API
conformance:
- id: openapi
  conforms: true
  version: 3.0.3
  evidence: >-
    openapi/4k-garden-diebian-ai-openapi.json declares openapi 3.0.3 with 58 paths, 63
    operations and 90 component schemas; parses cleanly.
- id: oauth2
  conforms: false
  evidence: No oauth2 securityScheme is declared and no authorization endpoint exists.
- id: oidc
  conforms: false
  evidence: /.well-known/openid-configuration is absent on all five hosts probed.
- id: rfc9457
  conforms: false
  evidence: >-
    Errors use a bespoke {code, msg, data} envelope with the wildcard media type '*/*';
    no application/problem+json and none of the RFC 9457 members are present.
- id: idempotency
  conforms: false
  evidence: >-
    No Idempotency-Key header on any of the 43 mutating operations. See
    conventions/4k-garden-conventions.yml.

  conforms: true
  style: page-number
  evidence: >-
    page / page_size query parameters with page, page_size and total in PagedTaskVo and
    PagedConsumptionVo.
- id: rfc8594
  conforms: false
  evidence: No Deprecation or Sunset headers are declared or documented.
- id: json-api
  conforms: false
  evidence: Bespoke response envelope; no JSON:API media type or document structure.
- id: odata
  conforms: false
  evidence: No $metadata surface and no OData query options.
- id: scim
  conforms: false
  evidence: >-
    The API carries a real enterprise membership surface (invite, accept, reject,
    remove member, change member level) but implements it bespoke. No SCIM schema URN
    appears anywhere in the contract.
- id: fhir
  conforms: false
  evidence: Not a healthcare API.
- id: fapi
  conforms: false
  evidence: Not a financial-grade API.
domain_standards:
  market: ultra-high-definition video production, distribution and AI video enhancement
  note: >-
    REWARD-ONLY check, and this contract declares no domain standard. Probed for the
    standards that would be meaningful in this market and found none of them referenced
    anywhere in the contract or its schemas.
  probed:
  - id: smpte-timecode
    conforms: false
    evidence: >-
      Task schemas carry original_duration, original_fps, original_resolution and
      output_resolution as free-form numbers and strings; no SMPTE identifier or
      timecode type is used.
  - id: cta-wave
    conforms: false
    evidence: No CTA-WAVE or common-media-application-format reference in the contract.
  - id: emvc-imf
    conforms: false
    evidence: No IMF/Interoperable Master Format package or composition playlist concept.
  - id: mpeg-dash
    conforms: false
    evidence: No manifest, adaptation-set or streaming-delivery surface in this contract.
  - id: ebu-core
    conforms: false
    evidence: No EBUCore or media metadata vocabulary in the 90 component schemas.
  result: none-declared
  penalised: false
compliance_certifications:
  published: false
  note: >-
    No trust centre, SOC 2, ISO 27001 or equivalent certification page was found. The
    corporate site does publish Chinese regulatory operating licences - an ICP filing
    (粤ICP备18012413号), a network culture operating licence, a radio and television
    programme production licence, value-added telecom business licences and a National
    High-Tech Enterprise certificate. These are jurisdictional operating permits, not
    information-security certifications, and are recorded here as such rather than as
    a compliance programme.
