  67 with the first stage of this rota.  Should the item already be associated with
  68 a rota, move it from that rota to this rota.

 124
 125 Aim here is to return $report augmented with content for this rota.  We
 126 delegate to $stage->investigate.
 127
 128 The report will include some basic information and 2 primary reports:
 129
 130 - per rota report in 'rotas'. This report is mainly used by admins to do check
 131   & compare results.
 132
 133 - branched report in 'branched'.  This is the workhorse: emails to libraries
 134   are compiled from these reports, and they will have the actionable work.
 135
 136 Both reports are generated in stage based investigations; the rota report is
 137 then glued into place at this stage.
