A cutout cut in several pieces around tabs, as PEP programs often are, made
pre-post review report every piece's lead-out and the part's open fragments
as incomplete. Review now proves such open cuts release nothing: within the
part they touch other cuts only at their own ends and form no loop (each
closed contour with its leads counting as one point), and leads at open ends
stay out of the gap beyond them. Anything else stays incomplete. Plan Cutting
keeps refusing to certify its own tabs followed by a lead-out.
