SIMULATOR Will Scotland win Group C in the 2026 FIFA World Cup?

A live, interactive instrument for dissecting a single binary position. Sweep the inputs and watch every indicator recompute — payoff geometry, Kelly growth, Bayesian posterior, KL divergence, cost waterfall, Monte-Carlo equity fan, forecast calibration. Companion to the live /feed/pm-will-scotland-win-group-c-in-the-2026-fifa-world-cup page.
