  title: Civitai Generate From a Catalog Model Version
  summary: Resolve a catalog model version's AIR, generate an image with it, poll, and read the result.
  description: >-
    Bridges the Site catalog and the Orchestration generator. The workflow
    resolves a model version from the Site API to obtain its AIR identifier, then
    submits an imageGen workflow on the Orchestration API that references that AIR
    as the model, polls the workflow to completion, and reads the generated
    output blob URL. Because operation ids are unique across both specs they are
    referenced bare, while two source descriptions are declared. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
