We present a structural determination of the muon decay time obtained exclusively from the orbital architecture of the muon as made explicit in viXra 2505. 0135, without resorting to external phenomenological constants or additional fit parameters. The muon is described as a composite orbital configuration selected by a rigid minimum in the space of mass and magnetic anomaly errors, whose metastability emerges as a dynamical property of the system. Orbitals and sub-orbitals are characterized as vibrational modes with proper frequencies. The decay is modeled as a cumulative process, in which the structure progressively loses coherence through internal dissipative channels. This process is governed by how effectively the phases of three sets of frequencies—internal exciters, primary selectors, and anomalous dissipative targets (defined by the inversion phenomenon) —manage to lock in time. For this purpose we introduce a beating operator based on nearest-integer locking to quantify dynamical residuals and construct, in a non-arbitrary way, a selection probability and an overall rate constant. We show that while purely energetic weightings fail, a minimal dynamical weighting defined by phase compatibility between targets and primaries correctly closes the problem. The resulting lifetime agrees with the experimental value with a relative error of the order of 10^-6, establishing that muon decay can be understood as an emergent collective property of its orbital structure and phase dynamics, without introducing new fundamental constants.
