  title: Anchore Image SBOM and Vulnerability Pull
  summary: Confirm an image is analyzed, then export its CycloneDX SBOM and its vulnerability report for downstream compliance use.
  description: >-
    A supply-chain evidence pattern. The workflow reads the image record to
    confirm the analysisStatus is analyzed and branches to stop early when the
    image is not yet ready, then exports the CycloneDX Software Bill of
    Materials and pulls the vulnerability report so both artifacts can be filed
    together as compliance evidence. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.

  summary: Verify analysis, then export the SBOM and vulnerability report for an image.
  description: >-
    Confirms the image is analyzed and, when ready, retrieves the CycloneDX SBOM
    and the vulnerability report for the supplied image digest.
  inputs:
    type: object
    required:
    - authorization
    - imageDigest
    properties:
      authorization:
        type: string
        description: HTTP Basic authorization header value (e.g. "Basic dXNlcjpwYXNz").
      imageDigest:

        description: The SHA256 digest of the image to export evidence for.
      vtype:
        type: string
        description: Vulnerability type to report (os, non-os, or all). Defaults to all.
