"""native_enc_diff.py — CAN 输出编码回归（不碰网卡，无 Python 后端依赖）。
|
|||
|
|
|
|||
|
|
阶段 4 切换后 Python 基准已删除；本脚本改为对照 native_enc_golden.json
|
|||
|
|
（阶段 2 与 Python _fill_can_out 逐字节对拍通过后固化的 4 组用例）。
|
|||
|
|
byte0 是 seq（守护进程状态相关，每次 enctest 都 +1），不参与比对；
|
|||
|
|
其余 383 字节必须逐字节一致，另校验 seq 两两 +1(跳 0) 的递增语义。
|
|||
|
|
|
|||
|
|
用法：native 在 8090 跑着即可（不需要 open/OP）：python native_enc_diff.py
|
|||
|
|
重新生成金标准（需 legacy 备份里的 ecat_server.py，一般不需要）：见 git 历史/zip。
