Joint strong-lensing plus dynamical modeling of SDSSJ1433+6007 with maximally flexible mass-sheet transformation yields H0 = 73.2^{+4.8}_{-4.7} km s^{-1} Mpc^{-1} at 6.5% precision under flat LambdaCDM with DESI Omega_m prior.

Spatially resolved kinematics show SLACS lens galaxies have nearly isothermal total mass profiles (mean γ=2.04) with average mass-sheet parameter λ_int=1.01, consistent with no measurable bias from power-law assumptions in cosmography.
