Description (short version) We report the empirical measurement of causal propagation speed in inertial Ricci flow on a discrete 10-dimensional manifold with topology T⁴₃₂ × ℝ⁶. A localized metric perturbation (Dirac pulse) is injected into the flat 10-dimensional metric field whose tensor retains all 55 independent components of a symmetric 10×10 matrix, and its wavefront is tracked at multiple distances along the 4 compact dimensions. The Heavy Ball integrator transforms the parabolic Ricci flow equation into a hyperbolic telegraphist equation: ∂²g/∂t² + γ(∂g/∂t) = c²∇²g This transformation endows the discrete metric field with a finite propagation speed. We derive this analytically and confirm it experimentally: the curvature signal at distance d=4 is identically zero at step 1, demonstrating a strict light cone that is mathematically impossible under classical (parabolic) diffusion. Furthermore, we observe chromatic dispersion in the discrete vacuum. Finally, upon macroscopic saturation of the periodic boundaries.
