Your question is Design Refresh Failure Alerting Pipeline. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You need a pipeline that catches two classes of issues: refresh failures and unexpected data behavior. The design should detect missed or failed refreshes quickly, score time-series anomalies on key metrics, and route alerts with enough context for triage while keeping noise under control.
