The Euler-Hernández Identity: Translating e^(iπ) + 1 = 0 as the Fundamental Logic Gate of Finite-State Spacetime

This work formalizes the ontological and mathematical transition of Euler's identity from the classical paradigm of continuous calculus (C∞) into a fundamental operational instruction within the Theory of Finite Systems. We propose that the fundamental equation rewritten as eiΦRH + 1 = 0 does not represent an idealized geometric rotation in an abstract complex plane, but rather the intrinsic hardware error-correction protocol (Garbage Collection) that prevents information saturation collapse at the Hernández-Valdivia Limit (εHV ≈ 10-70m2). By integrating the Ramanujan-Hernández Packing Factor (ΦRH) as the real phase argument, we demonstrate that the existence of antimatter (logical operator -1) is a mechanical imperative to guarantee the stability and positivity of the modified Hamiltonian HHV spectrum, definitively resolving the Map-Territory Confound and eliminating Ostrogradsky ghosts without requiring the ad-hoc postulation of the Dirac sea.
