+"""dump_kicad_vec.py — 把 KiCad 板的离散几何导成 JSON，供 cmp_vec.py 比对。必须用 KiCad python 跑。
+
+输出（单位一律 mm，KiCad 原生坐标系：y 向下）:
+  vias.json   [{x, y, drill, top, bot, net}]
+  pads.json   [{x, y, layer, net, ref, pad, drill}]
+  tracks.json [{x1, y1, x2, y2, width, layer, net}]
+  meta.json   {counts, layers}
+
+用法（KiCad python 路径见 ~/skills_env.md 的 KICAD_PYTHON）:
+  D:\\KiCad\\10.0\\bin\\python.exe dump_kicad_vec.py \\
+      --board E:\\Kicad_design\\FOO\\FOO.kicad_pcb \\
