All hackathon work is on the hackathon-forecast branch (repository link above). CaliMojo Forecast adds a play-money forecasting layer to CaliMojo, an open-source Facebook poker platform. Players receive 1,000 free tokens daily — never purchasable, never transferable, never redeemable — and take parimutuel positions on AI-generated yes/no questions about economics, technology, culture, and weather. No sports, no real-money gambling. 

Every question is created with explicit settlement parameters — a named objective data source (e.g. FRED, BEA, FOMC), a source reference, and an exact settlement rule — modelled on CME futures settlement. Resolutions publish a public record page showing the outcome, the observed value, reasoning, and cited sources, followed by a challenge window before pro-rata settlement. Forecasters build a Brier-score reputation shared with the poker tables. The work also hardened the platform's player login, its historic weak point. 309 automated tests, all passing.
