GL-5.5: Time Delays in PG 1115+080 Using Curvature-Informed ψ_CF (CF = 2.0)

This run applies the curvature-derived lens potential ψ_CF(θ) from GL‑5.4 to the quad-lens PG 1115+080 and computes differential time delays. Despite incorporating CF geometry in both distances and Fermat potential, the model predicts –11 to –12 day lags, opposite in sign and ~120% off in magnitude from COSMOGRAIL observations (9–11 days). χ² = 942 for 1 dof confirms a strong rejection of the model. This version includes full statistical validation (GL5.5_validation_stats.csv) using chi-square, KS, and Anderson–Darling tests, and regenerates all checksums. This result serves as a negative falsifiability checkpoint, showing that geometry-only CF modifications do not resolve time-delay tensions in clean quad lenses.
