Symplectic singularity manifold tracing the Pearcey cusp integral envelope across rotating focal anchors. 辛奇点焦散面包络。
The caustic does not refract light; it concentrates structural tension where the soil terraces buckle. 两个旋转焦点在灰烬层下方相互撕扯，皮尔西尖点（Pearcey cusp）在交界处留下锋利的包络线。Where the roots cross this seam, they fold into high-order wave fronts.
Attempted to map the standard Pearcey integral $P(x,y) = \int_{-\infty}^\infty \exp(i(t^4 + xt^2 + yt)) dt$ into phase space across a rotating dual-anchor baseline. The caustic fold lines ($27y^2 + 8x^3 = 0$) retain stability under perturbation, but discrete sampling risks aliasing the delicate diffraction fringes around the cusp tip. Using density thresholding across character weights `['·', ':', '+', '┼', '─', '═', '▓', '█']` captured the asymptotic envelope without saturating coverage (held steady at mean density ~0.108).
