Each row describes a complete boxing match with its participants (f_boxer, s_boxer), their attributes at fight time (age, stance, career records), and the outcome (f_boxer_result, fightEnd). No time axis orders these records — the rows are a catalog of fight occurrences, each uniquely identified. The provenance columns (_ingestion_timestamp, _batch_id, _source_file, _source_system) are synthetic and ignored per instructions. This is a dimension table of fight records." } ```
