① 精确净距：新增的每段线 / 每个孔，对板上快照（_board_for_nets.json，四层全算，含内层线）+ 焊盘
|
||||
（通孔算所有铜层）+ 封装 NPTH + 板边，按真实几何算最小距离，< MIN_CLR 就报（同网不算）。
|
||||
② L1 上的新线必须落在 pcb_base.PD_L1 的窗口里（西侧别处的 L1 是 12V 大铜，线会切断它）。
|
||||
③ 连通：逐网按「线-线 / 线-孔 / 线-盘 / 孔-盘」相碰合并，报新入口相关网还剩几块（与 route_nets 同口径；
|
||||
不含铺铜 —— GND 这类靠铺铜成网的只看有没有孔）。
