cbb 48cc566c3f exp: 轮次33——限幅实测要付5.1pp到达(57.4→52.3%);GPU真实周期36.7ms≈27Hz,瓶颈是重复几何而非推理
- 四组单变量对照(同256题同seed):base / inc_cap / gap_margin 0.5 / 两者同开
  限幅后 到达 0.5742→0.5234、time_ok 0.3906→0.2656、2s误差比 0.210→0.279、超VMAX 1.0→0.0、刹停几乎不变
  → 之前那部分到达率是超速换来的;损失在逼近末段,不在刹停
- 0.5mm 余量门只付 3 题(0.5742→0.5625);但 plans['gaps'] 在 0.5mm 截顶,5mm 护栏可达性需抬 cap 重算
- 前提更正:eval_cl 不传 steps、rollout 默认 steps=1(policy.py:156 一步生成),先前按 steps=16 得到的
  "当前配方 116ms≈8.6Hz" 作废;真实配方 36.68ms P50 / 49.17ms P99 ≈ 27.3Hz
- 归因更正:空算子 0.028ms、空 sync 0.005ms、encode 2.27ms → 不是启动/同步地板;
  单步推理仅 7.2ms 且 K=1→8 免费,周期里 ~27ms 是 cum_xf+宽相位的重复计算
- certify_uniform 挂上后 36.7→45.3ms(n=8)/49.6ms(n=16)
- kin_torch 补 a/b 形状守卫(脚本里广播不一致会算错 view),测试 30→31 项
