Column name "docs_indexed" strongly signals a count/quantity (real_additive naming). However, this is an instantaneous state measure on a PATH table - the number of documents indexed AT each timestamp, not a delta. Large magnitude (max 14M), unbounded range, strictly non-negative, contains zeros - all consistent with additive family. The key distinction: this is a snapshot level at each sequence step, not a flow/delta, making it ordinal_additive (sum across entities at fixed time; last/rank along sequence). Classified as ordinal rather than real_additive because summing instantaneous counts across timestamps is not meaningful without normalization. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
