`verificar_condicoes`Use before an agent trusts, buys or acts to test 1 to 10 explicit conditions against one public HTTP or HTTPS page. Best fits offer and warranty checks, seller identity or authorization checks, and policy compliance checks. Returns confirmed, rejected or uncertain for every condition with textual evidence when available, plus source, verifiedAt, verificationId and pageHash. Missing evidence produces uncertain, not a false confirmation. Use preview_verification first when the buyer needs a free example. PT: Verifica condições com prova auditável.
