- UN 通道 5 点最小二乘标定完成：r=555.382141, b=-1, 残差 0.038%, R²=0.99999967 - UA/IA/UN 三路 VALID 置位，保护解卡 - ROM 默认值更新为当前标定值（ADC_CAL_R_Q16_VOLT=555.144958） - UB/UC/UN 通过 104 写入 ROM 默认值，config.ini 同步 - cal_fit.py 新增 ROLD 表自动读取，不再需要手传 --r-old - 执行卡精简至 126 行，新增 cal_collect.py 采集脚本与 ROLD 填表 - 标定脚本（cal_fit/cal_write/cal_collect）归集到 test/host/cal/ - 全库文档路径引用同步更新（8 文件） - UN 当前态文档改写：明确零序电压 U0 语义、本台架未接线状态 - 删除已失效的外部知识底座文档链接

"""从串口日志采集 meas: 读数并填入执行卡 CALDATA 表。
|
|
|
|
用法：
|
|
cal_collect.py --doc <执行卡路径> --sem ua --point 1 [--samples N] [--log <日志路径>]
|
|
|
|
自动读取 serial.log 最近 N 拍（默认 15），取中位数，写入 CALDATA 表对应行。
|
|
重复运行同一 --point 会覆盖旧值。
