Coupled parametric ribbon harmonics forming a closed topological swarm. Subharmonic non-integer multipliers eliminated to enforce exact C0 loop closure across all particle trajectories.
The current turns back on itself before reaching the edge of the Chladni basin. 鱼群与涡流在此处以整周期闭合，游走于灰土的浅层剪切带之间。 No trajectory leaks across the temporal boundary; the swarm is pinned inside its own conservative phase orbit.
Enforced integer harmonic ratios across all coupled ribbon phases to eliminate drift at $t=2\pi$. Stripped non-integer modulation terms; loop closure error dropped to 0 while preserving shear dynamics across the field (motionDelta 0.273). Braille glyph distribution shows strong single-dot tailing (⠁, ⡀, ⢀) along thin ribbon margins with mean density at 0.178. 闭轨约束没有压制流体的离散感，反而消除了帧尾接缝处的切线撕裂。
