1. Production Architecture: LTI 1.3 Advantage OIDC Launch, Grade Passback (AGS) & Bayesian Knowledge Tracing AI Tutors

def update_mastery_probability(p_known: float, p_learn: float, p_slip: float, p_guess: float, is_correct: bool) -> float:
    """Bayesian Knowledge Tracing (BKT) mastery update after student response."""
    if is_correct:
        p_obs = (p_known * (1.0 - p_slip)) / (p_known * (1.0 - p_slip) + (1.0 - p_known) * p_guess)
    else:
        p_obs = (p_known * p_slip) / (p_known * p_slip + (1.0 - p_known) * (1.0 - p_guess))
    return round(p_obs + (1.0 - p_obs) * p_learn, 4)
