The cross-table context shows sibling tables (beer_ratings, place_ratings, favorites) that reference this table, confirming it defines the user catalog those tables build on. created_at and updated_at are descriptive timestamps (account creation/last update), not an axis ordering actions — they are attributes of the user record. The aggregated rating statistics (beer_rating_count, avg_beer_rating, total_activity_count) are derived attributes summarizing the user's activity, not state snapshots. This is a catalog of users: dimension." } ```
