Kelly growth-security frontier (MacLean, Ziemba & Blazenko 1992): for a strategy compounding at a fraction lambda of full Kelly, the probability wealth ever falls to a fraction alpha of its starting value is P = alpha^(2/lambda-1). Provide either lambda_fraction (to compute that probability) or max_probability (to solve for the largest lambda that keeps the ruin probability at or below it). Use when user asks "if I bet half-Kelly, what's my chance of ever losing half my bankroll?" or "what fraction of Kelly keeps my chance of a 50% drawdown under 5%?". Valid lambda range is (0, 2]; beyond 2 the probability is certain (1), not the raw formula value. Returns: probability, lambda_fraction (echoed or solved).
