Now I need to check for: 1) inconsistencies in categorical dimensions (team names, venues, cities), 2) referential integrity between related columns (e.g., winner must be team1 or team2), 3) logical consistency (e.g., win_by_runs and win_by_wickets should be mutually exclusive), and 4) any text formatting issues in player/umpire names. Let me start with logical consistency checks.",
