Votes out. A persona's downvote is a Dislike (POST /api/v1/statuses/:id/downvote and /undownvote, the viewer's own as
privapub.votes.downvoted). One vote a post: a changed vote is sent as the new vote alone, as Lemmy sends one, since an
Undo of the old one beside it could arrive after it and take the new one away; Undo goes only when a vote is taken back.
A vote on a post in a remote community goes to the community, which counts it, and to the author only when on another
server: one copy a server, since PieFed drops a second copy of an activity it has just seen. Mbin keeps a favourite
apart from a vote, so there a favourite stays after a switch to a downvote.
Feeds followed (owner decision 2026-10-07: through the server). Following a feed (Lemmy's multi-community, PieFed's feed)
keeps a FeedSubscription for the persona and nothing else; the new Service privapub_feeds (LocalActorKind.Reader,
reserved by migration _017) follows every community of the feeds read here, reconciled when a persona follows or leaves
one, when a feed's list is read again (kept as it was when it cannot be read) and every six hours. Its Following rows
carry FollowerKind, so nobody's home gets what it brings in and its unanswered follows are sent again as its own. The
persona reads GET /api/v1/timelines/feed/:id (the feed's threads, ours included) and lists its feeds at GET /api/v1/feeds.
Checked in the pasture, every scenario: 873 pass. The 14 failures are Hubzilla's (identical on the previous commit:
Hubzilla no longer answers a follow in this pasture since its restore) and two activities Smithereen never sent;
followsync passes once the pasture's restore is older than the 14-day pause. Live: alice's downvotes count as downvotes
on Lemmy 1.0 and PieFed, replacing her upvote; Lemmy 1.0 and PieFed take privapub_feeds' follows and their threads reach
the feed timelines.

Lemmy 1.0's multi-communities and PieFed's feeds (`type: Feed`) resolve as accounts: the feed's `following` is kept
once a day with its counts, each community in it is read in turn, and `/api/v1/accounts/:id/following` lists them.
Lemmy's feed carries the instance's key and its text in `description`; both are taken as they are. Following a feed
answers 422 until the owner decides how a feed is followed.
A post moved to another community (PieFed's Move{object: post, origin, target}), relayed by the community it leaves,
goes there with its thread; a move into a community we host is not taken.
Checked in the pasture: a Lemmy 1.0 feed and a PieFed feed list their communities (ours among them); a PieFed post moved
from its web code arrives moved, with its comment.
