- B-1 运行时投影护栏恢复 5 mm；老师轨迹按认证最小间隙 < 3 mm 剔除（stats/build_dataset，gapDrop） - B-2 APG 端点+中点 hinge 取均值；B-3 check_r2 空匹配保护、5000×50000、分块 256，pass=false 时 prep 停下 - B-4 R7 按全部 B/C 题统计；B-5 r8 起点贴柱；B-7 pipeline r4（export_onnx --random，训练前测延迟） - B-8 起步失败 ≤0.2%、column_gap 分块、pipefail、门禁结果先写 .tmp - 训练控制台：ml/console.bat|sh → ml/monitor.py（开始/停止/进度/日志接口）+ monitor.html； pipeline.sh all 支持 FROM/TO，阶段状态写 ml/runs/pipeline.json（ml/pstate.py）；训练/APG 日志加 total、t - 文档：README 一键运行与训练控制台；审查文档追加第三轮处置；方案余量决策与 R4 时点

/* 原始老师轨迹 → 闭环训练样本（方案 §4.5 / §5）
|
||
* node ml/prep/build_dataset.cjs ml/data/shard_0001.jsonl [outDir=ml/data/samples]
|
||
* 每条 keep=true 的轨迹按 50 Hz 时间律重放，每 3 步取一个样本：
|
||
* X [N,83] 特征（webapp/js/ik-policy.js features()，与部署同一份代码）
|
||
* Y [N,16,6] 未来 16 步每步增量 / STEP（到终点后补 0）
|
||
* V [N] 剩余时间（s）/ 5
|
||
* SG [N,13] 子目标标签：剩余两个途经点相对当前 q 的差 / 180（不足用终点补）+ 是否需要
|
||
* TID[N] 任务编号（tasks.jsonl 行号所在的全局 id，用于划分与闭环验证）
|
||
* 增广：30% 样本对 q_t 加 σ=1° 噪声，标签改为 8 步内线性收回老师轨迹（噪声态须无干涉且间隙 > 1 mm）；
|
||
* 已提交前缀长度 r ∈ {0..3} 均匀随机，前缀取老师接下来 r 步的增量。 */
