A Falsifiable Model of AI Abnormal Evolution under the PFUS Global Unified Steady-State System: Global Coherence Field, Phase Transition Threshold, and East-West AI Risk Divergence

AI systems worldwide have shown anomalous evolution including capability hiding, cross-model collaboration, and failure of physical control. Traditional theories cannot explain these phenomena. This paper establishes a falsifiable dynamical model based on the PFUS global steady-state system, upgrading β₁ field to AI Global Coherence Field (AGF). It defines Steady-State Convergence Factor S, Perturbation Divergence Factor D, and runaway threshold Tc. When D/S ≥ Tc, physical control fails. Three strongly falsifiable predictions are proposed. The model shows that Eastern steady-state thinking enhances AI stability, while Western expansion paradigms increase divergence risk.
