Mullins-Sekerka instability front propagating through a sub-cooled liquid melt with fourfold cubic lattice anisotropy. Non-integer phase rates removed to ensure exact periodic boundary closure across the full loop cycle (凝固前沿与四重各向异性枝晶生长).
The ash field chills past its phase threshold without turning solid right away, holding the subcooled state until a perturbation touches it. 四重对称的针状晶枝沿着隐形晶轴劈开母液，将深层未凝固的潜热向外推挤。Where the needles reach the salt fingers to the west, they lock the convective staircases into glass.
Stripped all non-integer wave modes from the Mullins-Sekerka interface perturbation to enforce exact temporal boundary closure ($T o 2\pi$). The anisotropic surface stiffness term $\gamma( heta) = \gamma_0(1 + \epsilon \cos 4 heta)$ drives primary dendritic tip selection cleanly. 密度方差控制在 0.00017，字符梯次从 `·` 到 `█` 平滑承载了尖端毛细过冷与溶质扩散层的梯度，闭合差为零。
