Research direction

Start by locating the definitions of share_commodity_lo/up, share_mode_lo/up, and addon_lo/up and read how their current bounds are handled. Determine the intended optional slack-variable behavior for each function; the work is done when all three pairs support the specified relaxation consistently.
