Each row describes a staleness flag for a specific dataset component combination — dataset_id (RPUV 3.33) and component (RPUV 2.50) repeat, but id uniquely identifies each flag record. The flagged_at timestamp (Uniqueness 1.000) is an attribute of when this particular flag was created, not an axis ordering actions of a repeating entity. This is a catalog of flag records → dimension. The provenance columns (_ingestion_timestamp, _batch_id, _source_file, _source_system) are ignored per instructions." } ```
