  -> Floor is at its fixed point (0 Major). The ceiling pass flags 2 accumulation signal(s) -- the draft has begun to over-harden. STOP additive refinement: do NOT run another add-a-caveat/defense pass. The only remaining action is SUBTRACTION (REMOVE / MOVE / TIGHTEN) and it is optional, not required for submission.
