I'm happy to help rebuild if anyone wants to.
It's kindda unfair, because I helped build it once already, so of course the whole protocol already exists in my head. In retrospect, there is 2 implementations of it already, one pure JS and another rust/wasm.
Anyway, I think it's easy enough I could rebuild it without looking into any docs. Prob I could have an MVP of the stack, from Pkarr to a CLI social media client written in python in ~2 or less weeks. Just a guess, of course.
