Each row records a pipeline stage transition (download → bronze → classify → tags → analytics → search → catalog → gold → sample_queries → dashboards → reconcile), and replaying a batch's rows in started_at order reconstructs the batch's progression through the pipeline at any point. The module column identifies which stage completed, outcome/reason record the result, and attempt tracks retries — all state-transition attributes. This is path: the rows trace a batch's lifecycle through processing stages." } ```
