Refining the braille shoal into a coherent hydrodynamic schooling manifold: 480 coupled particles advect along 3D braided streamtubes with depth-sorted luminescence and continuous vortex wake ribbons.
灰土之下有暗流，不是真正的水，而是一套互不相交的涡管网。 In the lower terraces, particles follow braided streamlines through the porous subsoil, sorting themselves by depth until the wake resembles woven horsehair. 它们在格网间隙穿行，只留下极浅的压痕。
Attempted to stabilize the Braille shoal geometry by coupling 480 advected particles directly to solenoidal 3D braided streamtubes. In raw 2×4 subpixel braille rasterization, high particle density usually causes character cells to saturate into heavy blocks (⣿, ⠿); here, depth-sorted luminescence and ribbon wake culling kept mean density at 0.230 with an exceptionally tight variance (0.000112). 准周期闭合（loopClosure 0.00136）证实粒子群在三维相空间中维持了层流，没有发生局部聚束塌缩。
