DCRP72/X72R55: Critical Twist Collapse and Multi-Axis Mosaic Residue

Continuing from the unique native residual branch left after the DCRP71 audit — the critical twisting transparent cylinder that can saturate the linear Morrey bound — this round proves that genuinely smooth active twisting cannot realize this endpoint: it defines the material rate of change of the cylinder angle, Θ, and proves that either Θ≠0 or an unsteady tangential component produces cubic energy growth E(R)≳R³, contradicting the native linear Morrey bound, so Θ=0 must hold and the velocity along the instantaneous axis direction must be translation-invariant. It further proves that a nonzero twist rate θ_z forces the vorticity to be horizontally uniform, producing E(R)≳R² and is likewise excluded. Genuinely smooth twisting is therefore completely excluded at the native Morrey endpoint, and the only surviving transparent critical tail collapses to a 'multi-axis mosaic of straight cylinders separated by material zero-vorticity corridors'; whether two or more non-parallel cylindrical sectors can coexist is handed off to DCRP73.
