Read one scan and its accumulated list of places

Every place holds subjects, the number of the basket corroborated there, its reach (the way in), the ai_authority of the domain, its exact pages, and client_present, which says whether the account already recorded a corroboration there. The list ACCUMULATES over every check, deduplicated by URL, so seen_in_checks counts checks and never citations. controlled is what each company publishes on its own site, and rivals the competitive set the engine names. To act on a place, add a quest with its URL.
