  title: AWS SAR Update Application Metadata
  summary: Read an application, update its descriptive metadata, then read it back to confirm the changes.
  description: >-
    Maintains the descriptive metadata of an existing serverless application.
    The workflow reads the current application to capture its present state,
    patches the author, description, home page URL, labels, and readme, and then
    reads the application back to confirm the updates were applied. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
