  title: Amazon ECR Registry Audit
  summary: Page through every repository in a registry following the DescribeRepositories token loop.
  description: >-
    Audits an entire Amazon ECR registry by describing all of its repositories
    and following the nextToken pagination loop until every page has been read.
    The flow requests the first page of repositories, then branches on the
    presence of a pagination token to keep requesting subsequent pages until the
    registry has been fully enumerated. Every step spells out its AWS JSON
    request inline, including the documented X-Amz-Target header, so the flow can
    be read and executed without opening the underlying OpenAPI description.
