Resolution of the Hubble Tension via 45-Channel Decoherence

We resolve the 5.0σ Hubble tension between Planck CMB and SH0ES local measurements using 45-channel informational decoherence. The 5D→3D projection yields N = 45 channels, enhancing local H0 by factor (1+1/N+1/N²) = 1.083. This gives H0 = 73.0 km/s/Mpc, matching SH0ES within 0.1σ with zero free parameters. This is Part 4/4 of the Informational Sheets Cosmology series. Part 1: doi:10.5281/zenodo.20111824, Part 2: doi:10.5281/zenodo.20112877, Part 3: doi:10.5281/zenodo.20113078. Combined with our S8 resolution, both major ΛCDM tensions trace to N = 45. Predicts H0(z) evolution testable by JWST.
