@earlwarren hello 👋 I'm not familiar with those images, but most of my work is in the main branch, although it requires to activate feature flags (you have links there: https://docs.gitlab.com/ee/development/activitypub/ )
That being said, there is not much to be used yet, as the first actor is not done implementing. I'm going to give more details in the codeberg issue where you pinged me.
@kik that's exactly what I was looking for 😍
It is ok that it is still ground work and wiring. Forgejo is pretty much at the same stage, with only federated stars implemented, with no UI.
I'm setting up the CI and creating the conditions for GItLab and Forgejo to communicate via ActivityPub, even if it means doing it in the most basic way.
