The 10% Window: A Structural Model of Civilian Stability Across Forces, Agents, and Constraints

This paper introduces the "10% Window" as a structural model of civilian stability across historical and modern civilizations. It argues that stability is not the default condition of human life, but a temporary outcome emerging from the interaction of three structural forces: centralization, constraint (decentralization), and civilian optionality. The model integrates:- Structural forces (power, constraint, optionality)- Intelligent agents (AI systems, AI-dependent humans, sovereign humans)- Temporal outcomes (stability windows vs instability phases) Drawing on comparative historical analysis across major civilizations (China, Europe, Japan, India, and Iran/Persia), the paper proposes that ordinary civilians experience genuine stability conditions for approximately 8–12% of recorded history. This work connects and extends prior frameworks developed by the author, including:- Civilian Stability Index (CSI)- Tri-Species Civilization Model (C-06)- Natural Rupture Theory (NRT)- Constraint-Observed Intelligence (COI) The goal of this paper is not statistical precision, but structural explanation. Stability is not designed.It emerges.
