Column name contains "count", a strong real_additive token. The data is strictly non-negative integer counts (86.8% zeros, max 244, mean 0.37) with unbounded upper range, characteristic of an extensive quantity that accumulates under volume union. No evidence of ratio behavior (center far from 1.0, contains zeros). High confidence real_additive. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
