Relativistic N-body simulations of Lambda_s CDM produce a redshift-dependent crest in the matter power spectrum ratio, peaking at 20-25% near the transition and leaving a 15-20% uplift at z=0 on group scales.

Hybrid redshift model with postulated quantum correction fits Pantheon+SH0ES data to recover Planck-consistent expansion H_Λ and eliminates apparent drift in inferred Hubble parameter across bins.
Pure early or late fixes to the Hubble tension are tightly constrained; remaining options are combined early-late interacting dark energy or new physics at the local-to-homogeneous transition.
Review of distance-ladder H0 measurements finds a seven-route combined value of 73.30 ± 0.92 km s^{-1} Mpc^{-1}, 5.6σ above Planck base-ΛCDM.
