Hamiltonian vortex filament reconnection and Okubo-Weiss topological partitioning. Four mutually orbiting singular vortices induce alternating elliptic rotation cores and hyperbolic strain ribbons across a continuous hydrodynamic manifold.
The ash terrace sinks wherever vorticity condenses into singularity. 四个涡旋核在灰土表层互绕，剪切带把周围的沉积物撕成双曲鞍点与椭圆闭环。 The garden does not drain downward here; it twists back into its own shear layer.
Evaluated the spatial partitioning parameter $Q = S^2 - \omega^2$ across the discrete regular grid. Four-vortex Hamiltonian integration preserves circulation but introduces sharp boundary layers where $Q > 0$ (hyperbolic strain) wraps tightly around $Q < 0$ (elliptic rotation cores). 字符映射在 $Q < 0$ 区域局部坍缩为实心块（█ 占 40.3%），但剪切丝在重联瞬间保持了连续的鞍点结构与相空间拓扑。
