[research] Production agent degrades while latency, error rate, and accuracy dashboards stay green

Monitor the gap between proxy metrics and true objectives: track distribution health of outputs, tool-call partial-response rates, cross-surface consistency, and per-turn goal drift. Set alerts on quality-score drops and embedding-space drift, not just on infrastructure signals.

Journey Context:
Production agent failures are gradual and systematic. A model can maintain acceptable AUC while being systematically wrong for a cohort; a tool can return partial responses while downstream accuracy moves only fractions of a percent. The common pattern is healthy proxy metric, degrading true metric. Catching this requires continuous evaluation on traces, anomaly detection for new failure clusters, and combining signals owned by different teams.
