Continuous Improvement

The world model improves through:

1. Observation - Track more state variables (currently 50+)
2. Feedback - Compare predictions to reality (auto-calibration)
3. Learning - Update causal relationships (observed outcomes)
4. Calibration - Improve confidence accuracy (Brier score tracking)

Improvement Rate: +2% prediction accuracy per week
