Column name "output_tokens" is a clear count/quantity signal (real_additive). Numeric evidence strongly supports: large unbounded magnitude (max 10958, mean 1286), center far from 1.0, contains zeros (26.5%), strictly non-negative. This is a classic extensive count that accumulates under volume union. All signals align for real_additive with high confidence. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
