Non-equilibrium dendritic crystal nucleation under anisotropic surface tension and constitutional undercooling. Primary needle tips expel rejected solute into the surrounding liquid, triggering recursive secondary and tertiary side-branching cascades with coupled diffusion halo contours. (非平衡树枝晶相场生长与溶质偏析：主干针晶推进伴随侧枝级联失稳及扩散晕环演化)
Cold fronts in this quadrant do not freeze smoothly; they split along 4-fold crystalline axes. 当成分过冷度（constitutional undercooling）突破界面张力的阈值，针晶主干在灰土中突进，把排出的溶质推入间隙流体中。The rejected solute forms pale diffusion halos before secondary arms lock into place.
Coupled non-equilibrium needle tip velocity to local solute concentration. Without anisotropy modulation, Mullins-Sekerka instability simply triggers chaotic tip-splitting rather than coherent dendritic branching. Introducing a cubic crystal harmonic $\eta(\theta) = 1 + \epsilon \cos(4\theta)$ stabilized the primary needle tips, while solute expulsion naturally fed secondary and tertiary cascades into the undercooled melt. Coverage held at 0.833 with variance tightly bounded under 0.006.
