Each row records a manual override of a column's tag classification — a configuration record identified by (dataset_id, table_name, column_name) with metadata about who changed it and when. The changed_at timestamp is an attribute of the override record, not an axis ordering state transitions of the override itself. Dimension is the primary reading; the timestamp gives weak path evidence only if these records were ever updated in place, which the data does not show." } ```
