notes: >-
  Fiddler does not publish a machine-readable OpenAPI spec or an enumerated
  application-level error-code registry publicly. This catalog captures the
  documented error envelope shape and the standard HTTP status codes the REST
  API returns; specific per-endpoint error reasons are surfaced in the `errors[]`
  array at runtime.
