description: Entity-relationship graph for the Diebian AI super-resolution API, DERIVED from the $ref
  graph and id-reference fields across the 90 component schemas in the published OpenAPI. The provider
  publishes no object reference, so entity descriptions are not asserted beyond what the contract states.
  Response-wrapper schemas (the ApiResponse<T> generics) are excluded; only domain entities are modelled.

id_prefixes:
  published: false
  note: Identifiers are bare int64 values; no prefixed or typed id scheme is used.
gaps:
- No published object reference.
- No id prefixing or typed identifiers.
- Entity descriptions absent from the contract - every schema carries only a title and property types.
