  title: Appian Export an Application Package
  summary: Resolve an in-flight package for an application and export it as a downloadable deployment artifact.
  description: >-
    Drives the Appian export side of the CI/CD deployment lifecycle. The
    workflow first reads the in-flight packages for an application to resolve
    the package UUID, then starts an export deployment for that package,
    polls the deployment until it leaves the IN_PROGRESS state, and finally
    surfaces the download URLs for the exported package ZIP along with a link
    to the full deployment log. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.

  description: >-
    Looks up the in-flight packages for an application, selects the most
