Abstract: The transition from quantum to classical behavior remains one of the central open problems in fundamental physics. Decoherence theory describes the dynamical process by which quantum superpositions become effectively classical, but does not identify a sharp structural threshold. We present an algebraic criterion for the quantum-classical boundary derived from a single-parameter (N = 3) framework called Trichiral Theory (TT). The framework produces a palindromic degeneracy spectrum whose values — 1, 2, 4, 8, 12, 20, 54 and their mirror — each reduce to closed-form expressions in N (respectively: 1, c, N+1, N2 −1, N(N+1), (N+1)(N+2), 2N3). At the first stable state of this spectrum (degeneracy g = 4 = N+1), the four known forces admit a natural partition into two pairs: the Strong and Weak forces, which are capable of forming new bound states via a three-edge closure mechanism, and the electromagnetic and gravitational forces, which interact with existing states but do not produce new bound configurations. Notably, the gravitational coupling derives as VG = 2VEM 2, linking the hierarchy problem to the quantum-classical boundary through a common algebraic origin. We argue that this 2+2 partition at g = 4 constitutes a precise, falsifiable criterion for the onset of classical behavior, and present three experimentally relevant predictions.
