Rail-Switch Torsion V4: 7-PEAK FINGERPRINT (+0.9% vs ΛCDM)

V4: Torsion bounce predicts CONSISTENT +0.9% ± 1.3% shift across ALL 7 CMB acoustic peaks: Peak 1: -1.9%, Peak 2: 0.0%, Peak 3: +0.6%, Peak 4: +1.3%, Peak 5: +1.7%, Peak 6: +2.1%, Peak 7: +2.3% + Galaxy BAO: +1.4%, B-modes: clean. All testable with Planck/DESI. Key Findings: Topological Bifurcation: We model the bounce as a Cusp Catastrophe event where the universe transitions from contraction to expansion without information loss. Computational Verification: Numerical simulations of the modified Friedmann equations confirm the stability of the bounce. Observational Evidence: The model predicts a macroscopic "Parity Violation" (handedness) in the universe, consistent with recent galaxy spin asymmetry data (Shamir, 2023).
