Refactored testfisico.py: removed duplicate plots, replaced phase‑space section with energy‑vs‑velocity analysis. Added Rodal (2025) irrotational metric with Hessian‑based proper energy density. Added Fuchs (2024) WarpShell audit (via warpax): zero negative energy across full subluminal parameter space. New convergence test and phase‑space sweep for Fuchs metric. Centralized constants in constants.py. Added pytest suite with Ford‑Roman bound regression test. Updated README with full metric comparison table.
