  title: Cloudflare Create Firewall Rule
  summary: Create a filter expression, attach a firewall rule to it, then list the rules.
  description: >-
    Legacy firewall rules pair a reusable filter (a match expression) with an
    action such as block or challenge. The workflow first creates a filter from
    a match expression, then creates a firewall rule that references that filter
    id with an action, and finally lists the firewall rules in the zone to
    confirm the new rule is present. Each step inlines its request and asserts
    both the documented HTTP 200 status and the Cloudflare {success, result}
    envelope flag.
