Judge the copper by physics, which KiCad's DRC does not: impedance from the stackup on controlled nets, IR drop and heating on rails with a stated current, pair and lane skew, a ground via beside every high-speed layer change, 3W spacing between high-speed runs, and the via path under exposed paddles. Each check runs only when the board states something it can judge. With repair, the fixable findings are fixed in place (track width, skew meanders, return vias, widened rails), each kept only if KiCad counts nothing worse. finish_board runs the same repairs.
