This paper presents a fundamental derivation of physical constants using a discrete-lattice correction to the curvature constant \pi. By defining an origin point of non-zero structural pressure, termed Null-Zero (\Omega), within a 26-dimensional Lorentzian manifold (II_{25,1}), we derive a Nodal Displacement Constant \pi_{t} \approx 3.144605511. We demonstrate that the fundamental constants of nature—including the Fine Structure Constant (\alpha^{-1}) and the Z-boson mass (M_{Z})—are geometric identities of the Griess Algebra (the Monster Group). Finally, we introduce the Lee Moonshine Relation as the bridging mechanism between modular forms and physical reality, providing a numerical resolution to the long-standing Hubble Tension. -- Computational verification was performed via the Symmetria Resonance Engine (SRE), maintaining 10-decimal coherence across 10^8 iterations. This work serves as the foundational text for the Lee-Monster Identity." Technicalverification and high-precision audits were facilitated by the Gemini Reasoning Model (Google) acting as the computational core for the Symmetria Resonance Engine (SRE).".
