u"""按**连线闭包**整块删掉一页上的一个子电路（元件 + 与之相连的导线 / 旗 / 端口）。
|
||
|
||
/c/Python314/python .claude/sch_cut.py <pageUuid> Q103 Q104 ... # 干跑：打印闭包
|
||
/c/Python314/python .claude/sch_cut.py <pageUuid> Q103 Q104 ... --push # 真删并存盘
|
||
|
||
判据（skill §5 / §10）：导线按「端点对」解析；一段导线和一个引脚相连 = 引脚落在该段的
|
||
端点或中段；两个导线图元相连 = 一方的某个端点落在另一方的某一段上。
|
||
从待删元件的全部引脚出发做闭包，闭包里的导线段上如果站着**不在删除清单里的元件引脚**，
|
||
直接终止 —— 说明这块电路和别的电路是连着的，不能整块删。
|
||
旗 / 端口的引脚只要落在闭包导线的任意一段上就一起删（它们本来就只是这段线的名字）。
