Hubzilla 11.4.1 with its pubcrawl addon (peers/hubzilla.sh): the hlhd image on the shared MySQL, a cron sidecar, hzuser
and hzfriend made through Hubzilla's own PHP as public channels that speak ActivityPub. scenarios/hubzilla.sh, 20
checks: follows, posts, comments, likes, edits and deletions both ways, and a third channel's comment that the thread's
owner passes on, which PrivaPub takes on its FEP-8b32 proof. Known gap G-0010 (upstream): Hubzilla 11 keeps a follower
after its Undo{Follow}.
