u"""删掉 PCB 上「死网络」的铜：导线（铜层 1/2/15/16）+ 过孔。
|
||
|
||
/c/Python314/python .claude/pcb_prune_nets.py <pcbUuid> '<正则>' [--push]
|
||
|
||
判「死」的两条：① 网名匹配正则；② 网名不在任何焊盘上（孤儿网 —— 原理图删掉元件后，
|
||
它们的局部网 `$2N689` 这类还留在导线上）。空网名的导线不动（板框 / 手画铜带可能没网名）。
|
||
|
||
2026-09-06 为「74HC595 整窝挪到载板」写的：下板上 POGO*/EDL_EN*/HUB_RST/K*/KEY_*/SR_CAS*
|
||
那 900 多段铜整批作废；载板上 POGO*/EDL_EN*/HUB_RST 从排母来的旧线也要拆。
