This paper introduces Persistence Dynamics (PD), a dynamical formalism within the broader framework of Persistence Geometry, for understanding trauma, rigidity, metastability collapse, and adaptive recovery. Drawing from predictive processing, active inference, network neuroscience, and metastability research, the paper proposes that trauma is best understood not as static pathological memory persistence, but as collapse of viable reconstructive accessibility across constrained continuity landscapes. The framework introduces key concepts including continuity basins, reconstructive viability, residue-conditioned accessibility deformation, metastable flexibility, and viability-gated variability regulation. Within this formulation, PTSD rigidity, hypervigilance, avoidance, dissociation, and defensive stabilization emerge as expressions of narrowing accessibility geometry under prolonged destabilization pressure. Recovery is correspondingly reframed as regulated widening of viable accessibility under stabilized reconstructive conditions rather than unrestricted catharsis or simple symptom suppression. The paper integrates and extends contemporary work in predictive coding, active inference, metastability, flow dynamics, neuroplasticity, and trauma neuroscience by proposing a unified continuity-conservation architecture governing adaptive flexibility across time. It additionally introduces experimentally tractable predictions regarding trajectory diversity, metastable flexibility, residue persistence, network switching, synchronization adaptability, and accessibility widening across neural, behavioral, autonomic, and psychological domains. Persistence Dynamics is presented as a foundational component of the broader Persistence Geometry research program and as a proposed bridge connecting prediction, regulation, metastability, trauma rigidity, and adaptive recovery within a single reconstructive continuity framework.
