The Frequency Fusion Model (FFM): A Unified Rendering Substrate for Spacetime and Fundamental Constants

This paper introduces the Frequency Fusion Model (FFM), a novel computational framework that posits spacetime as a rendered output emerging from a pre-stressed 2D quantum octagonal lattice. Unlike the Standard Model, which relies on 26 independent free parameters, the FFM derives fundamental constants—including the Cosmological Constant (\Lambda) and particle mass ratios—from an 18-constant geometric architecture. We resolve the "Vacuum Catastrophe" by calculating the effective vacuum tension (\tau = -0.9914) on a Planck-scale substrate, yielding a \Lambda value consistent with observations within a 0.34% error margin. Furthermore, we provide a definitive, falsifiable blind prediction for the electron neutrino mass (m_{\nu_e} = 0.04722 eV/c²) and identify a specific resonance anomaly in high-energy scattering at 2.45 GeV. This work suggests that the discrete, non-Euclidean geometry of the vacuum substrate is the underlying hardware for all quantum and relativistic phenomena.
