GL-5: CF Gradient Fit — Distance-Only Diagnostic

This diagnostic run evaluates whether curvature-factor (CF) gradients can reconcile observed strong-lensing time delays across three clusters when applied only to distance geometry (i.e., DL,DS,DLSD_L, D_S, D_{LS}DL,DS,DLS). The CF gradient is fit using MCMC, modifying the comoving distances while leaving mass modeling and angular structure unchanged.The result shows that distance-only curvature fails to improve Δt predictions: the optimizer collapses to CF_grad ≈ 4e–9, effectively reproducing GR. This confirms that curvature-mass coupling and realistic lens geometry are essential for accurate time-delay modeling.This simulation serves as a falsifiability checkpoint within the Tejera-Ace Standard Model (TASM), reinforcing the necessity of full curvature-integrated lens physics in future runs.
