 * candidate investigator to convert messages of
 * `Boss::Msg::ProposePatronlessChannelCandidate` to
 * `Boss::Msg::PatronizeChannelCandidate`, and uses
 * the provided guide to help derive the patron it
 * proposes.
 *
 * If it is able to find a patron, this module emits
 * `Boss::Msg::ProposeChannelCandidates`.
