- Dislike and its Undo are kept as downvotes (Lemmy, PieFed, Mbin, Friendica) and shown with favourites as votes. - ChatMessage (Lemmy 0.19, Mbin, PieFed to those two) arrives as a direct message. - A deleted object's id is remembered for 90 days, so a Create that arrives after its Delete cannot bring the post back; the post's ObjectRecord goes with it. - A Join of one of our objects is answered with Ignore, as FEP-8a8e asks of a server without RSVP. - A 503 with Retry-After is waited out like a 429 instead of counting as a failure of the host (GoToSocial throttling, Mastodon's temporary key failures). - Status.privapub carries what a Mastodon Status cannot: object type, title, excerpt, cover, the author's source, link, video, audio and event details, and up/down votes, with every media URL proxied.
