      Record the two facts the original contract does not state: the API is
      unversioned, and it declares no error responses.
    update:
      x-api-versioning: unversioned
      x-error-responses-declared: false

      PROBED 2026-08-14 — an unauthenticated request to
      https://mailosaur.com/api/servers answers 401 with
      'www-authenticate: Bearer' and an empty body, contradicting the
      documented Basic scheme that actually works.
    update:
      x-observed-challenge: Bearer
      x-observed-401-body: empty

    description: >-
      No operation in this document declares a 4xx or 5xx response. The real
      error contract is catalogued in errors/mailosaur-problem-types.yml:
      400 returns a {type,message,parameters,model} envelope; 401 and 404
      return no body.
