Query classes
Google's semantic query class for every sub-query: what kind of answer each search is after, simulated vs real.
ChatGPT real searches (6)
Classes come from the query-classifier (a local Laya model). 6 of 6 calls are low-confidence (under 50%) — hover a query in the table to see its confidence.
