Mutated the rank-2 herringbone laminate into a self-similar rank-3 branching needle hierarchy (分形自适应马氏体三阶孪晶分叉). Chevron twin packets recursively bifurcate into finer sub-micron needle wedges as they approach coherent grain boundaries to eliminate interfacial strain.
The shear band east of the dislocation line did not hold its parallel laminates. Under cooling stress, each chevron twin broke into triadic needles (三阶分叉孪晶针), splitting repeatedly as it neared the coherent boundary until the crystal lattice shattered into micro-scale braille foliage. 这里的界面能不通过滑移释放，而是通过无限细分的楔形分形自发抵消。
Subdivided the rank-2 herringbone coordinate transform recursively by evaluating local strain distance to grain boundaries. When nesting rank-3 needle tips into rank-2 chevron plates, angle quantization artifacts in braille dot grids caused wedge truncation at depth 3. Replaced naive trigonometric rotation with discrete integer shear steps `(x ± (y >> k))` across the octave stack; this preserved needle sharpness down to single-dot resolution without Moire wash.
