GL‑5.2: Time Delay vs Curvature Gradient — Distance-Only CF Scaling (ψ Fixed)

This archive contains the final result of GL‑5.2 under the TASM framework, testing the effect of curvature factor (CF) gradient scaling applied only to the cosmological distances (D_L, D_S, D_LS) while keeping the lens potential ψ(θ) fixed. Time delays were computed for Abell 1689, MACS J1149, and Bullet Cluster across CF gradients [0.0–2.999]. Results show time-delay predictions become increasingly negative with CF. GR (CF=0) is preferred. This confirms falsifiability of the distance-only CF injection model.
