Building upon the foundational principles of the Cartesian Relativity Framework (CRF) established in Parts I–III 1, 2, 3 and the Unified Field Equation of Coordinate Duality defined in Paper IV 4, this paper formalizes the mechanical architecture of the electron. By replacing the mathematical abstraction of the point-particle with the Rendered Address Cluster, we define the electron as a state of Threshold Confinement operating at the absolute limit of the lattice's rendering thresholds. This formalization provides a strictly deterministic, geometric derivation for Spin-½, defining it as a 720-degree algorithmic routing cycle required to maintain structural integrity (E/c2) against the Lower Rendering Threshold (h). The paper further resolves the observer-dependent paradoxes of legacy quantum mechanics through State Volatility, where the electron’s proximity to the rendering floor allows it to oscillate between the Rendered Address Index (RAI)and the Probabilistic Address Index (PAI). Furthermore, we demonstrate that atomic orbital transitions and the Lamb Shift 8 are governed by rigorous Newtonian kinetic conservation 7 and topological congestion. Finally, by defining the positron through Inverse Topological Routing, the framework mathematically resolves matter-antimatter annihilation as an Overwhelming RAI Collision. This preserves absolute energetic and kinetic continuity within the algorithmic cycle (dt), rendering temporal retro-causality 9 unnecessary by demonstrating that annihilation is a geometric cancellation of confinement loops that returns localized energy to a probabilistic state.
