However, the column name "index_bytes" strongly signals an absolute extensive quantity (storage size in bytes), not a ratio. The data confirms this: large unbounded magnitude (max ~18.7B), mean far from 1.0 (438M), contains zeros (33.6%), and strictly non-negative. These are classic real_additive characteristics - bytes accumulate when volumes merge. No multiplicative evidence overrides the naming and numeric signals. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
