        Two shapes reach the wire and both are modelled here as optional fields:

        the shared auth/role gate in [`super`] emits `{"error": ...}`, while

        [`super::json_message`] — which the handlers themselves use — emits

        `{"message": ...}`. Exactly one is present on any given response. This
        is

        documentation of what the service already does, not a new contract; a

        handler is not free to send both.

        error:

            - string

          type:
