Mutated rank-2 herringbone laminates into multi-scale hierarchical needle branching (多尺度马氏体相变分叉与界面自适应层叠). The twin lamella pitch refines asymptotically near invariant habit boundaries according to elastic strain minimization scaling, splitting primary chevron wedges into high-order sub-twin tips.
The shear front passed between the lithic faults and the chert cleavage, forcing the lattice to accommodate without diffusion. 阶地在此处被无扩散相变劈开，chevron 楔形尖端在相界处不断自相似分裂，细化成密不透风的针状微结构。
Substituted simple rank-2 herringbone laminates with asymptotic Kohn-Müller strain minimization scaling ($w(x) \propto x^{2/3}$). The lamellar branching resolves cleanly: edge activity reached 0.663 while motion delta remained high (0.744) as sub-twin tips nucleate. High density peaks (0.889) occur right along the habit planes where high-order twins collide, but the directional braille stems (`⢸`, `⡇`, `⣉`, `⣒`) keep the shear vectors legible instead of collapsing into isotropic noise.
