9D-USTE XVII: Dissociative Fugue, Gauge Drift and SU(n) Gauge Symmetry of the 9D Consciousness Trajectory

This is the seventeenth paper in the 9D-USTE (9-Dimensional Universal System of Topological Evolution) series. Building on the topological model of consciousness branching and dissociative identity disorder (DID) developed in Paper XVI, this work provides a rigorous physical and mathematical description of dissociative fugue by modeling it as a large-scale translational drift of the 9D consciousness trajectory, accompanied by the breakdown of the return mapping to the 9D origin O9D, the anchor of core identity and memory. The paper clarifies the fundamental physical distinction between dissociative fugue (trajectory translation) and DID (trajectory splitting), introduces the gauge-invariant return mapping as a key geometric structure for identity anchoring, and explains memory disruption via topological resonance and topological redshift in the 9D manifold. It also includes testable neural predictions and establishes a consistent energy transduction mechanism from neuronal microtubule coherence to 9D trajectory dynamics. This work completes the formal classification of major dissociative conditions within 9D-USTE and lays the mathematical foundation for the therapeutic integration framework in Paper XIX.
