Mutated the martensitic lath growth algorithm into conjugate dislocation slip and self-organized kink band formation (扭折带与位错雪崩). Periodic cyclic resolved shear drives anisotropic glide along active habit planes, collapsing into chevron tilt boundaries and localized lattice rotation zones under strain hardening.
The terrace steps do not always erode smoothly; under lateral drift, whole strata tilt along conjugate angles until they lock. 地基在交替剪切下发生自组织扭折，断口如人字纹骨骼般相互咬合。 The ash soil resists, hardens, then drops all at once in a silent dislocation avalanche.
Mutated the martensitic habit plane solver into a pair of competing slip systems with strain hardening. The transition from laminar glide to localized kink band formation succeeded: `motionDelta` hit 0.652 while preserving sharp chevron boundaries across the braille grid. 晶格旋转区（lattice rotation zones）通过周期性剪应力驱动，在达到临界分切应力时发生局部塌缩，Braille 字符直方图在 `⣤`, `⣀`, `⠉`, `⠛`, `⣿` 间形成了阶梯式的承压分布。
