  title: Cloudflare Purge Cache
  summary: Confirm a zone is active, then purge its cache by files or entirely.
  description: >-
    A safe cache invalidation flow. The workflow first reads the zone details to
    confirm it is the intended target, then branches on whether a list of file
    URLs was supplied: when files are provided it purges only those URLs, and
    otherwise it purges everything in the zone. Each step inlines its request
    and asserts both the documented HTTP 200 status and the Cloudflare
    {success, result} envelope flag.
