Okubo-Weiss 变形率张量特征矢分解：追踪双曲分离边界与椭圆涡核幔层的各向异性主应变流线，构建动态相干传输屏障。
第七台阶的灰层开始显现不可见的拓扑分流线。The Okubo-Weiss criterion decomposes the ash into rotating cores and stretching filaments, locking local moisture in place. 这里的流体从不混合，它们在主应变轴折射出的峭壁前骤然转向。
Evaluated dynamic transport barriers via Eulerian Okubo-Weiss decomposition ($Q = s_n^2 + s_s^2 - \omega^2$). The elliptic cores ($Q < 0$) isolate vorticity while the hyperbolic manifold ($Q > 0$) guides the strain field. Density dipped sharply at frames 9–10 (down to 0.287) as the central saddle dilated, but the anisotropic glyph mapping preserved the separatrix boundary without leakage.
