Post-Emergent Structural Persistence Across Physical and Adaptive Scales in a Coupled Non-Equilibrium System

This study investigates whether persistent organizational regimes can span fundamentally different scales within a coupled non-equilibrium system. Using a structure-aware diagnostic framework, we analyze the post-emergent behavior of a system combining subatomic vacuum-level fluctuation diagnostics and large-scale human adaptive dynamics over the period 1950–2025. Rather than modeling mechanistic causation or equilibrium behavior, the analysis focuses on regime-level properties including topology invariance, causal density, complexity, self-similarity, and robustness to perturbation. Across extensive control ensembles—incorporating randomized shuffles, null-structure tests, symmetry-breaking perturbations, and multi-order-of-magnitude noise sweeps—the coupled system consistently converges to a stable, low-dimensional organizational regime. Despite substantial local variability at both physical and adaptive levels, the global structure remains invariant, exhibiting zero topology variance and persistent causal organization. These findings indicate that the coupled system operates within a stable structural phase rather than as an unconstrained stochastic process. The results suggest that persistent organizational constraints may operate across scales in complex non-equilibrium systems, offering a regime-level framework for interpreting resilience, predictability, and systemic risk without invoking mechanistic reduction or domain-specific unification.
