+    /c/Python314/python .claude/r2/fan_check.py --push     # 过了就下发（导线 + 过孔）
+
+判三样（`router_check.py` 只判前两样，第三样是这块板特有的）：
+
+1. 新导线 ↔ 板上异网铜（L1/L4 的线、过孔、焊盘）：净距 ≥ `MIN_CLR`
+2. 新过孔 ↔ 板上异网铜 / 异网孔（孔到孔按钻孔间距 `DRILL_CLR`）
+3. ⛔ **新过孔 ↔ 内层（L15/L16）上的线**：过孔是通孔、穿过内层，而布线器只认 L1/L4，
+   这一层关系它**根本不查**。底板的内层名义上是整层地、不布线，但板上实测有 125 段
+   用户手布的内层线（HUB_RST / +3V3_HUB / IO0 / INT# …）⇒ 不查就是往人家线上扎孔。
