V4.33 的 92k 是 0Ω 实验板(68nF)语境; 产品回到三极管板(43nF)后 92k≈70µH 过严, 40~70µH 正常线圈会误报 → 上限 108k = L≈50µH (保留最小合理线圈) test_coil_range 边界 108/109 全绿; 语法 0 error 文档: devlog V2.33 / spec V2.14 / manual V2.11

*
|
|
* 验证对象: TaskLoop.c coil_monitor() (V4.26 拍板规格)

|
* 默认低频档口径(43nF 三极管板): 空场频率合理窗 20~108kHz, 出界即判定电感量不合理
