Reproducibility package for "Clock–Optics Unification (COU): separating geometry and clock effects in gravitational lensing"

This archive contains the reproducibility code and synthetic data generator for the manuscript “Clock–Optics Unification (COU): separating geometry and clock effects in gravitational lensing via a unified Fermat/eikonal formalism”. The package includes an FFT Poisson solver, synthetic convergence-map generation, single-plane and multi-plane lensing routines, FITS input/output utilities, image-finding routines, and time-potential recovery from synthetic delay differences.
