The BECU-OLON EAR V5 framework introduces a nonlinear geodynamic architecture for the analysis of regional tectonic organization, coherence evolution, and metastable transition dynamics in seismic systems. Building upon previous EAR formulations, this version extends the framework through regional morphology subclass separation, nonlinear phase-flow vector fields, depth bifurcation manifolds, and multiscale coherence tracking. The framework analyzes seismic catalogs using localized geographic and depth-domain filtering, allowing shallow crustal systems, strike-slip environments, and deep subduction regimes to evolve independently within reduced nonlinear morphology spaces. EAR V5 integrates coherence observables, Critical Flow Index (CFIu), LOCK-Z dynamics, surrogate ensemble testing, autocorrelation memory analysis, and nonlinear trajectory organization metrics inside a unified state-space formalism. The presented results suggest that some tectonic systems may exhibit transient coherence organization, long-memory behavior, and non-random structural clustering beyond purely stochastic activation backgrounds. Deep subduction systems appear to display stronger directional phase locking and coherence persistence relative to shallow strike-slip environments. This framework is presented strictly as a scientific research and retrospective nonlinear analysis platform. It is not an operational earthquake prediction or public warning system. All results should be interpreted as exploratory indicators of structural organization and metastable geodynamic evolution within complex lithospheric systems.
