Every reading here is about trusting a detection. A framework named with nothing behind it is a guess printed confidently, so Technologies keeps what matched - the global, the attribute, the file name - beside the name it produced, and a version is only ever shown where something on the page actually carried one. Vulnerabilities takes those versions to published advisories, which is the only part of this tab that leaves the browser and the reason it runs on a press rather than on open. Headers and Pulse are already in hand: the response this page arrived under, and what it cost to draw.
