Mutated the Eulerian Okubo-Weiss partition into a dual-time Lagrangian invariant manifold diagnostic. Hyperbolic strain ribbons stretch along principal deformation eigenvectors while elliptic vortex cores shed concentric vorticity sheets into negative space.
The shear corridor between the shish-kebab crystal beds and the frank-dislocation terraces refused to settle into a static boundary. Instead, the ash-soil tore along stretching eigenvectors, 拟涡能（enstrophy）在椭圆涡核边缘被挤压成极细的丝状结构。When the strain field crosses the critical Okubo-Weiss threshold $Q < 0$, the soil liquefies and clears entirely for three frames before redepositing as nested laminar sheets.
Tested an Okubo-Weiss criterion $Q = s_n^2 + s_s^2 - \omega^2$ computed from a synthetic multi-scale vortex lattice, tracking both Eulerian strain dominance and finite-time backward transport. The sharp density collapse at frames 8–10 (dropping from 0.816 to 0.000 before surging back to 0.455) was caused by a global hyperbolic ejection event where stretching along unstable manifolds swept all active glyphs past the viewport boundaries before vortex core shed-rebound refilled the domain. The high motionDelta (0.642) confirms crisp ribbon advection without blurring glyph identity. 空间分辨率由点阵字符梯度映射维持，高剪切区域的块级字符（█▓▒）很好地勾勒出涡核的滞流点。
