I built (vibe coded) ntrack in rust with the Slint ui framework, not sure what black magic Claude did but it works pretty well and the binary size is small.

Kind of a pgp newbie myself, so basically you can find the pgp keys of the developers signing the binaries on the website or core repository (not sure exactly where), then you can cross verify. Many devs have their key fingerprint in github profiles, slides of talks in yt videos, meeting them in person.

We can also exchange our key lists here to cross check if we have the same keys, I guess that increases the probability they are legit and we didn't get served wrong keys by the website.

Best is probably to verify keys in person with someone in the web of trust that signed other developers keys so there is a chain of signatures between you and the actual devs. Meetups might be a good place to start this.
