R29 将嘴部软件行程收至 0–10° 并修正下头壳；指定腿罩/电机配对在四条新质量慢速轨迹中的最低保守名义间隙下界为 11.407 mm。31 根线的防磨件和四工况动力学已补充，但嘴部闭合扭矩仍超过现行 0.05 Nm 结构限制，连续线束及制造公差尚无实物证明，不能放行行走。
沿用R25：31根头部导线改为底部接入，保留前盖与原外形比例；收拢活动线束并取消原侧面专用线孔。底部走线特写。仍为工程候选，离散转头检查不代表连续运动或实物验收。
历史四步回放：R27：R26整机运动回放。 使用已保存的195.44秒实际积分轨迹，逐帧驱动完整R26装配并复核覆盖件的刚体干涉增量；R26质量下的动力学和实物行走仍待验收。
