The kernel's last-resort boolean retry moves the tool 1.3 µm and turns it 2 µrad. For a partition that puts the cut beside the face it was meant to run along and leaves a cell bounded by slivers (the open boundary at x = 130 on the crank half). halves() now refuses a result-altering retry and names it.
