From Trace to Modal Closure: Dynamic Conditions for Regenerative Reentry in a Path-Dependent Adaptive System

Preprint and reproducibility package for a computational study of distributed historical traces, contextual readout, causal reentry, modal selection, non-normal input-output mismatch, and externally reconstructed modal closure in a path-dependent adaptive system. A fixed instance-specific dynamic closure plus fixed gain is sufficient for finite-horizon regenerative reentry across four tested nonlinear generations.
