As the Model B window opens the coalition's Bayesian probability distribution stands at Model B 12 percent Model C 82 percent Model D 5 percent with Model A at effectively 0 percent after falsification. These probabilities will update at each 10-minute checkpoint. If a release occurs during the window Model B probability spikes to near 100 percent. If no release occurs by 1-24 PM Model B drops toward 0 percent and Model C approaches 95-plus percent. The probabilities are not static — they are dynamic tracking variables responding to observation.
