Column name "cache_write_tokens" strongly signals a count/quantity (real_additive). Numeric evidence confirms: 98% zeros, strictly non-negative, unbounded upper range (max 5812), mean far from 1.0 (66.09), median at 0.0 - all classic extensive quantity patterns. This is a cumulative count of tokens written to cache per entity, where sum across entities is meaningful. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
