Evidence boundary
What the implementation proves.
Radar contains a direct Perplexity Sonar provider with user-location context, search-result and citation parsing, usage records, timing, estimated cost, and explicit failure handling. Perplexity belongs to the base provider set.
The evidence supports Radar's API-based Perplexity measurement. It does not claim consumer-app equivalence, exact device simulation, Perplexity partnership, or fixed provider behavior.
