  # This class is responsible for exposing methods that are required by both linked data and
  # non-linked data authorities.  As of v5.10.0, those three methods are: params, search_header,
  # fetch_header.  Those are the methods that are used in {Qa::LinkedData::RequestHeaderService} and
  # in {Qa::Authorities::Discogs::GenericAuthority}.
  #
  # The intention is to provide a class that can behave like a controller object without being that
  # entire controller object.
