- 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

"""两点标定写入器：C_SE_NC_1 两段写下发 r/b，C_RD 读回复核。
|
||
|
||
复用台架已验收主站库 test/host/iec104_master.py（不重写协议层）。
|
||
地址（App/algo/run_par.c run_par_104_write）：r = 0x8050+slot，
|
||
b = 0x8048+slot；slot UA0/UN3/IA4。执行卡：
|
||
docs/测试说明/专项验证/ADC多点标定执行流程.md §4。
|
||
|
||
用法：
|
||
python test/host/cal_write.py --r 0x8050=995.99 --b 0x8048=-1 \
|
||
--read 0x8050,0x8048 --expect 995.99,-1
|
||
python test/host/cal_write.py --read 0x8050,0x8054 --expect 995.99,29.52
|
||
|
||
写入顺序刻意**先 r 后 b**：b 走 adc_cal_set() 置 VALID 位，而 VALID 要求
|
||
r 已在带——先让 r 就位，语义干净。--b 必须是整数码值。
|
||
PN（否定确认）= 执行段拒绝：看串口 `[ERR] set ch=... rejected` 行。
|
||
输出纯 ASCII，可直接重定向归档为台架证据；exit 0 全过 / 1 有失败 / 2 连接或协议错误。
