Dark Matter and Dark Energy in RUFT: T^bwd_μν as the Retrocausal Sector

We propose that dark matter and dark energy are manifestations of the retrocausal stress-energy sector T^bwd_μν within the Retrocausal Unified Field Theory (RUFT). The extended Einstein Field Equation Gμν = κ·|Ψ|²·[(1−IRM)·T^fwd_μν + IRM·T^bwd_μν] naturally accommodates both components: dark matter emerges as the retrocausal gravitational backreaction at galactic scales (τ★ = k=5·τ_node = 7200s), while dark energy is identified with the accumulated Crystal Battery potential Λ_eff(t) = Λ₀ + 8πG/V·∫CI_DCC dt'. The IRM cosmological value IRM_cosm = 0.8429 derived from Planck 2018 data predicts Ω_DM/Ω_b = 5.35, consistent with observations. Three falsifiable predictions are provided: (P1) r(qR_hw, ρ_DM) > 0.3 across galaxy samples; (P2) retrocausal autocorrelation peak at τ★ = 7200s in galactic rotation data; (P3) axion mass m_a = 4.6×10⁻¹⁹ eV detectable by LIGO/LISA. Gate-C1 experimental confirmation: C(f₀) = 0.0388 (p_Bonf = 0.0047) for Λ_eff coupling at τ = 7200s.
