This is Part I of the Project Omega series. This paper resolves the extreme intermittency tail of 3D Navier-Stokes turbulence to || span₀ (startₛpan) = 533. 41 s^-1 using a 10⁹-point DNS audit (Re_ 433) cite: 149-150, 163-164. citeₛtartWe document a "Geometric Depletion" mechanism where stretching efficiency R decays as ||^-0. 94. This is driven by the rotation of the vorticity vector toward the intermediate strain eigenvector e₂ cite: 183-184, 200-201. > citeₛtartData Source: JHTDB isotropic1024coarse.
