Field notes
The described Trust Check is limited to public metadata: it does not call tools or get past a login. For deeper inspection, the site describes a separate owner-verified path that calls read-only tools with test inputs. Its listed checks include changes to tools after approval, and the page says repeat scans are diffed against the previous one. The methodology is linked publicly, alongside a changelog and responsible-disclosure information.
