   * @param request - the key, the method, the surface, and the cancel signal.
   * @returns `authorized` once the flow's record is committed during this
   *   attempt and observed, or `cancelled` when the human declined or the
   *   caller withdrew.
   * @throws {AuthorizationError} code `NO_FLOW` when nothing claims the key,
   *   `UNKNOWN_METHOD` when the named method is not one the flow offers,
   *   `ALREADY_IN_FLIGHT` when an attempt is already running for the key, or
   *   `NOT_COMMITTED` when the flow resolved without committing a record
   *   during the attempt.
