This is the evidence for every fact on this page, across Locals, Services, Team, Visit, Reputation and Updates. Each reference names the fact, the source, what kind of source it is, and the date it was checked, with a link and an archived copy so anyone can verify it. Visitor references are dated firsthand accounts. AI guesses record what an AI engine said on that date, not what is true.
