We present the fourth paper of the Cosmic Information Theory (CIT/TIC) series, consolidating the twenty-two predictions from Papers 1–3 into a unified experimental program and delivering three deferred calculations. (i) The velocity-dependent self-interaction cross-section sigmaT (v) = sigma₀ / (1 + v²/v₀²) ² with v₀ = mₚhi/mchi = 6000 km/s, resolving Bullet Cluster constraints while producing cores in dwarf galaxies. (ii) The free-streaming scale lambdafs ~ 30 kpc for mchi ~ 1 GeV, corrected from v2 using the mean thermal momentum = 3 TQCD = 450 MeV. (iii) BBN compatibility confirmed: ΔNₑff ~ 10^-6, derived from the observed Ω_χ h² = 0. 12 (Paper 1), six orders below the Planck bound. The Chandrasekhar-analog mass for dark fermions is MChᵈark ~ 5-10 Mₛun (corrected from v1), making dark compact objects detectable by LIGO/Virgo as stellar-mass mergers with no EM counterpart. The estimated DCO merger rate is ~10^-8 Mpc^-3 yr^-1, comparable to the observed black hole binary rate. Twenty-eight predictions are tabulated across five experimental domains.
