Column name "column_count" contains the token "count", a strong real_additive signal. Statistics show strictly positive integers (min=5, max=423, mean=79.3) with large unbounded magnitude, centered far from both 0.0 and 1.0, consistent with an extensive count quantity. No zeros present, but the name and magnitude pattern overwhelmingly indicate a count measure that accumulates under volume union via sum. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
