Q-EOS: Qwen Economic Agent Society

A fully autonomous six-agent economic governance system powered by Qwen-Plus, PID control theory, and a three-layer safety framework. Q-EOS implements the Dynamic Control Buyback Mechanism (DCBM, arXiv:2601.09961) as a multi-agent architecture where Observer, Risk, PID, Policy, Governor, and Treasury agents collaborate to stabilize a token economy in real time. The system demonstrates measurable efficiency gains over single-agent baselines: +3,351 USDC treasury surplus and 7x reduction in max drawdown over 30-day controlled experiments.
