Conditioning f_coll on tidal eigenvalues from small-box simulations allows low-resolution large-volume reionization runs to recover HI power spectra to within 2-5% on scales k less than 0.5 h/Mpc.
DESI DR1 full-shape galaxy clustering constrains Omega_m = 0.296 ± 0.010, H0 = 68.63 ± 0.79 km/s/Mpc, and sigma_8 = 0.841 ± 0.034, consistent with LambdaCDM and Planck.
