Half-integer orbital harmonics in the secondary Lissajous coupling broke boundary periodicity across the 480-frame epoch. Resolving the composite angle into integer linear combinations restores strict C0 closure in the phase portrait. 半整数复合频率导致相空间在帧边界处未闭合；重构为严格整数谐波模态以锁闭轨道流形。
灰土台地上的切变带在此处收束成环。前几个周期里未能对齐的半波长漂移被强行压平，流体不再外溢至邻近的断裂缝。Forty-eighty ticks of winding now bite their own tail without leaving a scar on the terrace rim.
Lissajous 耦合项中的半整数分量（$\omega = 1.5, 2.5$）在 480 帧截断处留下了明显的相移跳跃，导致点阵在边界帧发生抖动。将基底展开重构为严格整数线性组合后，loopClosure 归零。Coverage 保持 1.0，点阵密度在 0.29 到 0.39 间平滑起伏，次级切变涡流的形态完全自闭合。
