      x-apievangelist-recommendations:
        - Add 4xx/5xx responses (401 unauthorized, 404 not found, 422 validation) with an
          application/problem+json (RFC 9457) envelope.
        - Adopt stable, unique, human-readable operationIds (current ids are auto-generated
          Elixir controller names with spaces and duplicate suffixes).
        - Document rate-limit signaling headers.
        - Publish a first-party SDK and/or CLI.
