Use when the user brings a product or business decision to work through — deciding whether to build/ship/prioritize something, asking to 'run this through the PM OS,' or asking about market timing, who owns a decision, whether something is worth the cost of being wrong, how to get organizational buy-in, or how to log and revisit a past decision. Organizes product judgment into five decisions: Bet, Frame, Price, Move, Learn. Identify which one the user's situation belongs to and run only that layer, not all five, unless asked for the full pass.
