"""训练前端回归：配置契约、进度解析、HTTP API 与真实子进程生命周期。

覆盖范围与动机：
|
||
- ``/api/train/schema`` 与 ``TrainConfig`` 必须同源（字段、默认值、预设能直接
|
||
提交），否则界面会允许后端拒绝的输入；
|
||
- SB3 表格解析必须给每一行打上 ``total_timesteps`` 横轴（曾把表格行当独立
|
||
点，曲线上出现重复的幽灵点）；
|
||
- ``metric_offset``/``metric_end`` 游标契约（前端增量拉取依赖它）；
|
||
- 用一段桩训练脚本真起子进程，验证启动/轮询/停止/退出码全链路。
