Daedalus is the codename of Devuan's current release (same as bookworm in Debian) and it's on the top of tree too. Well, almost. Anyway, it's visible on gh.

I would not say Armbian is the basis of the project. Its builder is just a useful tool. I tried to distance from it as far as possible, bearing in mind Devuan's arm-sdk as the next toy to play with. I gave it a try as well, but found Armbian builder is better.
