Column name "avg_value" explicitly signals an already-averaged intensive level. Center-of-mass (median 0.95, mean 14.9) is far from 1.0 and shows wide spread (max 446), ruling out ratio_multiplicative. High log_symmetry_gain (6.0) suggests log-normal distribution common in averaged quantities. The column represents a pre-computed average at entity grain, making sum meaningless and mean the natural rollup reducer. Classified as intensive_additive with high confidence. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
