- 显卡精度档（B=1,K=8,steps=1）：推理 FP32 7.68 / FP16 8.31 / BF16 8.58 ms，整周期不变而FP16 P99 46.6→55.6； 动作偏差 FP16 0.0050°、BF16 0.0377° ⇒ 该批量下不是算力受限，保持 FP32 - float32 认证：48段×9点×15组对的间隙差 max 1.32e-4 mm（有1例高估）→ 现 eps=1e-4 已被越界，要用需 ≥2e-4； 判据结果两边一致（各24接受、0 仅f32安全、0 符号翻转），暂不放宽 dtype 守卫 - 流水线复用特征间隙：第一版42.1→31.8ms 但等价性检查不过（我取缓存行索引取错，差3.19mm）； 修正后只剩 −3.1ms 且缓存行与新算差 6.3e-5mm（不同 batch 的结合序）⇒ 放弃 - 顺带修掉轮次34日志里重复的章节标题
