The table catalogs foreign key relationships discovered between tables — each row describes one relationship with its quality metrics (confidence, coverage, cardinality). The created_at timestamp (RPUV 9.88, 8 distinct values) is an attribute recording when the relationship was analyzed, not an axis ordering actions or state changes of the relationship itself. This is a metadata catalog of discovered relationships → dimension." } ```
