x-note: Enhancements API Evangelist derives on top of the harvested Measurabl spec. The original is never mutated.
  The two substantive gaps this overlay addresses are (1) the document declares NO servers array, so no client or
  generator can resolve a base URL from the spec alone, and (2) 3 of 3 operations carry no operationId, which blocks
  operation-level referencing from Arazzo, agent skills and SDK generators.

  description: Record how credentials are actually obtained; the spec declares the token URL but not the provisioning
    path or the fact that no scopes exist.
  update:
    x-provisioning: Client key and secret are issued per organization by a Measurabl Customer Delivery Manager;
      API access requires Premium Tier entitlement.
    x-scopes: none - the clientCredentials flow declares an empty scopes map, so authorization is entitlement-based
      rather than scope-based.

  description: '3 of 3 operations in this document have no operationId. API Evangelist does NOT synthesize them
    into the spec: an invented operationId would be indistinguishable from a published one downstream. This action
    records the gap so it can be raised with Measurabl. Agent skills in skills/ therefore reference operations by
    METHOD + path, which are verbatim real.'
