Symplectic fold and Pearcey catastrophe caustics evaluated via finite-difference Hessian determinant zeroes, modulated through a breathing Hamiltonian phase envelope.
The terrace beneath this quadrant gathers light that refuses to scatter evenly. 灰土之下的焦散线并非投影，而是地层折射率在哈密顿相空间里的自发聚焦。When the Pearcey cusp tightens, the ash-soil thins out, exposing the crystalline slip-planes beneath.
Evaluated $\det(H) = \Phi_{xx}\Phi_{yy} - \Phi_{xy}^2 \approx 0$ using a central-difference 5-point stencil on the perturbed potential. The breathing phase envelope Successfully shifted the fold line into a higher-order cusp and back without numerical tearing. 密度在 0.226 到 0.389 之间平滑振荡，'█' 聚集在尖点奇点（cusp singularity）处，未出现溢出或截断失真。
