  title: Civitai Identify a Model From a File Hash
  summary: Resolve a local model file's hash to its model version, then load the parent model.
  description: >-
    A common client-side reconciliation pattern. Given the hash of a model file
    on disk, the workflow looks up the matching model version, then walks back to
    the parent model for full catalog detail, and finally re-fetches the version
    to expose the complete file list and AIR identifier. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
