However, the column name "row_count" is a strong real_additive signal (count token). The data confirms this: strictly non-negative with zeros present (against multiplicative), large unbounded magnitude (mean 14.4, max 50.0, std 16.8), and center far from 1.0. A count is a classic extensive quantity that accumulates under volume union via sum. All signals align on real_additive with high confidence. </reasoning> <table_type_conflict>false</table_type_conflict> </result>
