What a pass means
This confirms that the image decodes with Ironfang's verifier - the same ZXing-based engine Renderwolf runs against every QR it generates before delivering it. It cannot guarantee that every camera, lighting condition, print process or embedded scanner will read it; contrast, quiet zone and print size all matter in the physical world.
Why we never open the link
A QR payload is untrusted input. The decoded text is shown exactly as it is, URLs are labelled but never fetched and never made clickable without you copying them deliberately - the entire point of verifying a code is deciding what it does before anything acts on it.
Need to generate styled QR codes automatically? Renderwolf verifies every QR it creates before delivery.
