Abstract: Driven net- and no-net-flux MHD turbulence simulations up to $10,\!368^3$ reveal sign-mixed velocity-magnetic, velocity-vorticity, and magnetic-current aligned patches below the energy equipartition scale. The first two angles scale as $\lambda^{1/8}$ and $\lambda^{1/16}$, while magnetic-current alignment varies weakly with scale. We develop and test a constant-flux transport model for departures from relaxed states, which predicts both exponents. These findings affect eddy anisotropy, reconnection-mediated turbulence onset, large-scale dynamos, and the nature of magnetized turbulence.
