@mro @aSeppoToTry To test the split-domain handle on a remote actor, you can look up @canary in your platform and see what handle it shows you. I just gave it a try, see attachment.
It currently shows the wrong hostname. That means it's using the ActivityPub ID to construct the handle, when the handle domain should be coming from the WebFinger result. See my checklist https://correct.webfinger-canary.fietkau.software/#developers or the SocialCG report https://www.w3.org/community/reports/socialcg/CG-FINAL-apwf-20240608/#reverse-discovery for details on how to fix it.
Btw: very cool project! 👍
