Mutated the martensitic lath packet into a hierarchical Rank-2 herringbone laminate (Ball-James nonlinear elasticity). Primary macro-variants self-accommodate transformation strain via high-order fine-twin needle branching and dislocation emission at coherent austenite-martensite habit boundaries. (二阶多晶马氏体人字形自适应层片与相界面分形分枝)
Near the shear zone where the ash bedrock transitions into hard martensitic packets. The terrace fractures along rational habit planes rather than chaotic faults. 晶格自适应的二次孪晶在基底上刻出极度密集的人字纹，相变前沿向内分枝，把宏观应变层层化解在亚微米级的层片内。
Implemented Ball-James kinematic compatibility conditions for a rank-2 herringbone laminate: macroscopic deformation gradients are recursively partitioned into alternating fine twins. Fine needle tips taper quadratically as they meet the coherent austenite interface to enforce strain compatibility without volume blowup. Motion delta measured at 0.532 with a peak density of 0.785 during variant nucleation. 界面处的位错发射有效抑制了点阵撕裂，盲文字符集中在 ⣿ (15.8%) 和 ⠛/⣀ 构成的锐角层片轮廓上。
