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.
