    An OpenAPI Overlay 1.0.0 capturing API Evangelist's derived findings about the Cloud Foundry
    Foundation's own CAPI v3 specification. It is applied ON TOP of the upstream document and never mutates
    it. Every action below records something the upstream spec does not state but that a consumer needs:
    that api.example.local is a placeholder for a self-hosted host, that the API has no idempotency
    mechanism, that a single operation is deprecated in prose only, and where the derived conventions,
    error, rate-limit and reversibility artifacts live.
actions:
- target: $.info
  description: Record the derived artifact set and the absence of an idempotency mechanism.

      note: >-
        No Idempotency-Key header appears on any of the 248 operations. Named-resource creates are protected
        by uniqueness constraints (422 CF-UniquenessError); unnamed creates such as tasks and deployments
        are not protected at all.

  description: >-
    Flag that the upstream server URL is a placeholder. Cloud Foundry is self-hosted; api.cloudfoundry.org
    answers HTTP 530 and api.example.local is not resolvable. The real base is api.<system-domain>, supplied
    by the operator.
  update:
  - url: https://api.example.local
    description: Cloud Foundry V3 API server
    x-placeholder: true
    x-real-form: https://api.{system-domain}
    x-note: >-
      Every Cloud Foundry is an independent deployment. There is no vendor-hosted endpoint, and no discovery
      document that will tell a client where one is. The host must be configured.
- target: $.paths['/v3/tasks/{guid}/cancel'].put
  description: >-
    Add the machine-readable deprecation flag the upstream spec omits. This operation announces DEPRECATED
    in its summary string only, so tooling that filters on OpenAPI's `deprecated` field sees it as current.
  update:
    deprecated: true
    x-replaced-by: cancelTaskPut
    x-deprecation-source: summary text "DEPRECATED - Cancel a task (short path)"
- target: $.components.responses.TooManyRequests
  description: Document the rate-limit response headers, which the upstream spec does not declare.
  update:
    headers:
      X-RateLimit-Limit:
        description: Requests permitted in the current operator-configured window.
        schema:
          type: integer
      X-RateLimit-Remaining:
        description: >-
          ESTIMATED requests remaining. Computed per Cloud Controller instance and rounded down to the
          nearest 10% of the global maximum, so it can read 0 while requests still succeed.
        schema:
          type: integer
      X-RateLimit-Reset:
        description: >-
          ABSOLUTE Unix timestamp at which the window resets. Not a delta in seconds. There is no
          Retry-After header on this API.
