Torsion Tensor Dynamics in the Triple Spin Framework: Full Covariance Analysis and BAO/CMB Consistency

Key Points

• To analyze the uncertainty in the Triple Spin Framework and its implications for cosmological consistency.
• Conducted complete uncertainty analysis of the model
• Developed a full covariance matrix
• Performed sensitivity analysis
• Verified the impact of BAO/CMB/lensing null
• Estimated H₀ value of 72.41 km/s/Mpc with uncertainties
• Generated a torsion tensor leading to a quintessence state (w_τ = -0.49)
• Confirmed zero free parameters in the model
