2 s 误差比逐题符号检验 s0 192好/64差 p=4.9e-16、s1 191/65 p=1.5e-15；时限内(≤1.3×老师) 0.2656→0.3320(+6.64pp)、0.2969→0.3398(+4.30pp)；行程比 −0.171/−0.171；碰撞仍 0、超 VMAX 仍 0。 到达只 +5/+3 题(McNemar p=0.42/0.68 ⇒ 噪声)，故不改默认口径、作可选口径入库。 代价：到达题末态误差 0.22→0.42 mm(判据壳 1 mm 内，余量 4.6×→2.4×)，两 seed 都涨。 对照可比性先证：控制臂 tie0 与轮次42 round42_K8cb1 的 22/22 键逐位相同 ⇒ 该配方跨窗口确定性 复现，本轮起新杠杆可用单臂对已落盘控制。 实现：select='pre' 用 fut[:,:,commit_n-1] 的终点误差(同一次 goal_err 只换点集)；两条可手算正对照 (前缀好/末端差 vs 末端好/前缀差 ⇒ 两口径必须选相反候选) + 不变式(commit_n=16 时与 endpoint 同选)； 49 项测试绿；n=16 冒烟证非惰性。候选表同步修准：backoff/ep_waste 两行状态改判掉，#29/#30 登记。
