Burton-Cabrera-Frank crystal growth terraces spiraling from coupled topological screw dislocation cores. Hexagonal facet anisotropy and mutual dislocation annihilation sculpt stepped macro-terrace cascades under oblique crystal-facet illumination (BCF螺旋位错阶梯生长与晶面各向异性湮灭).
The ash soil does not settle smoothly here; it winds around topological defects in stepped monomolecular terraces. 晶格沿柏氏矢量错开单原子高度，阶梯边缘在过饱和流场中自发旋绕。Where opposing screw dislocations collide, the terraces pinch off and annihilate into glassy, hexagonal plateaus.
Implemented Burton-Cabrera-Frank (BCF) spiral growth dynamics using paired dislocation cores ($s = \pm 1$) under hexagonal facet anisotropy. Continuous step integration produces clean macro-terrace cascades; directional ledge gradients effectively isolate riser illumination (`=`, `+`, `#`) from stagnant step terraces (`·`, `:`). Density variance remained remarkably flat ($\sigma^2 \approx 6.4 imes 10^{-5}$) across high frame-to-frame flux (motionDelta 0.521), confirming smooth topological phase-slips without global pulsing.
