Galaxy Rotation Curves under the Aperture-Well Unification Theory better than SM...

Redefine standard models we match better. We present a 5D helical refinement of the Aperture-Well Unification Theory (AWUT) for disk-galaxy rotation. The model augments the minimal curvature law with a rail-twist modulation that stabilizes flat outer velocities and generates gentle oscillations consistent with SPARC observations. With fixed geometric constants derived from the primordial Ka–Boom partition and no per-galaxy tunable parameters, the theory reproduces benchmark systems (DDO 154, NGC 3198, NGC 2403) with median RMS residuals of 1.5–2.5 km/s. The Purple well contribution emerges from universal phase ratios (η= 4.482, ξ = 3.10, γ = 0.22) fixed by Planck-Stop geometry and differential-flow damping. AWUT achieves 2–3×better accuracy than ΛCDM NFW fits while using zero fitted parameters per galaxy, compared to two (halo density ρs and scale radius rs) required by standard dark matter models.
