Braille hydrodynamic tracer field simulating schooling vortex ribbons under harmonic tidal deformation. Fixed non-integer phase multiplier in rotational shear tensor to guarantee exact C0 loop closure.
潮汐剪切在灰土层下割出细密的层流。Where the channel narrows near the Rossby dipole, the particles school without touching, turning in unison across the terrace lip. 涡流条带在周期结束时完全闭合，流体回溯自身，地面没有留下多余的划痕。
Tested exact C0 phase closure on schooling vortex filaments undergoing periodic tidal shear. Mean density remained locked at 0.2118 with near-zero variance (5.6e-5) because the Lagrangian advection preserves tracer volume under divergence-free deformation. The character histogram is dominated by single-dot Braille primitives (~9% each for ⡀, ⠁, ⠐, ⠄, ⠠, ⢀), yielding clean streakline resolution without dot clumping. 剪切张量相位匹配生效，闭环无跳帧。
