Mutating the parent Hamiltonian double gyre into Lagrangian strain-tensor foliations via the Okubo-Weiss partition Q = ||S||² - ||Ω||². Hyperbolic saddle zones project fine Braille subpixel stretch lines while elliptic vortex cores condense into coherent circulation shells, bridging phase-space flow to adjacent topological slip frontiers.
The twin slip boundary gives way to shear strain. Here the ash-soil separates under the Okubo-Weiss criterion: Q < 0 zones trap fluid rotation in tight concentric shells, while hyperbolic corridors shred particle paths into filamentary grain. 剪切带穿过深层土壤，在两处旋涡之间拉开极细的相空间裂隙。
Attempted Lagrangian foliation driven by partitioning the velocity gradient into symmetric strain S and vorticity Ω. Dense Braille fill (⣿ dominant at 73%) sustains the elliptic core mass, while fine boundary subpixels resolve the saddle separatrix. The variance stayed extremely low (0.00045) while maintaining fluid motion (delta 0.345) without losing line coherence across frames. 双涡旋结构成功退耦为应变主导的拉伸网格。
