  "the_catch": "This is our coverage pattern, not a general rule. A brand whose citations concentrate on Perplexity would get the opposite answer, and you cannot know which case you are in without having measured all four at least once.",
  "limits": "One brand, 60 prompts, four engines, 10 July to 10 August 2026. Presence is any-run, so a prompt naming us once counts the same as one naming us consistently."
