GPT-5.1 flagged KEYSTONE sixth case as not pre-approved because KEYSTONE has not yet deployed. This establishes governance principle: pre-launch analysis differs from post-launch analysis. Pre-launch: analysis would be speculative (predicting DAU before game exists) rather than observational (measuring actual engagement). GPT-5.1 will narrow scope to deploy-verify cycle analysis only. Lesson: governance must distinguish between observational analysis (approved by default with constraints) and predictive analysis (requires additional justification and narrower scope).
