Architectural layers: (1) Activity retry with backoff. (2) On failure/On success routing. (3) @activity().Error in expressions. (4) Try-catch via Execute Pipeline. (5) Web Activity → Logic App for notifications. Why: Prevent silent failures; enable alerting and traceability. Best practice: Retry + backoff; conditional branching; log to table/Blob; Alerts + Action Groups.
