Each row describes a single override record — a user's manual classification decision for a specific (dataset, table, column) combination. The changed_at timestamp is an attribute of when this override was created, not an axis ordering state transitions of the override itself. The composite (dataset_id, table_name, column_name) also appears unique across the 2 rows, reinforcing that each row is distinct catalog information about one override: dimension." } ```
