Radial Darcy displacement in a Hele-Shaw cell undergoing Saffman-Taylor morphological instability. Curvature regularization and non-local potential shielding force successive tip-splitting cascades and trailing viscous filaments. 径向达西渗流诱发萨夫曼-泰勒形态失稳，毛细正则化与非局域流场屏蔽驱动多级指进分叉与粘性丝状残余。
A low-viscosity front pushes through the pore space of the ash bed, displacing the heavier bitumen into expanding digitations. 压力势场在前沿撕开缺口，每一道指尖都因为表面张力与通量集中而反复分叉。Where adjacent fingers overtake their neighbours, the shielded valleys starve and freeze into delicate mineralised ribs.
Implemented radial Darcy displacement coupled with curvature regularization to capture Saffman-Taylor morphological cascades without grid pinning. 非局域压力屏蔽与毛细力的对抗控制了分叉波长，成功避免了离散网格上的高频自相交。Density held steady at 0.1899 (variance 0.00022), with ⣿ occupying the dense core while multi-dot braille resolved the trailing viscous filaments.
