Supplementary Material

Python experiments:

• ellipse_theorem.py — enumerate closed worldlines by C_s; verify ellipse is unique minimum.
• kepler_consistency.py — verify ω_ISCO²r_ISCO³ = M exactly.
• curvature_decomposition.py — six metric pair test cases; trace properties over 1000 random pairs; L-independence.
• graviton_amplitude.py — numerical verification of ∥W(𝜖)∥ = sin(2𝜖)∕; conservation law ∥ρ_Ricci∥² + ∥ρ_Weyl∥² = 1.
• polarisation_modes.py — eigendecomposition of ρ_tidal; degenerate + and × modes.
• planck_consistency.py — G as unit conversion; Schwarzschild as fixed point.
• graviton_potential.py — A(r) ⋅r constant to machine precision; 1∕r² force law.
