   *   1a) uncheck Included item -> mark as Added but unchecked
   *   1b) re-check unchecked Added item -> return it to Included check item
   *   2a) check Sources item -> mark as Added and checked

   *   3a) uncheck Included item that still exists as auto-detect -> mark as
   *       Detected but unchecked
   *   3b) re-check Detected item -> return it to Included and checked
   *   4a) check Sources item should also add any auto-detect items as Detected
   *       and checked
   *   4b) uncheck Sources item with auto-detect and auto-detect items should
   *       return to Sources and unchecked
   *   5a) uncheck a Detected item -> refreshing page should keep it as
   *       unchecked Detected
   *   6)  when nothing changes, refresh should not change any state
   *   7)  should never see an unchecked Included item
