Communities:
- a post addressed to a community (to, cc or audience) is accepted
according to its posting policy - followers, anyone, or moderators -
and GroupDistributor announces the whole activity with `audience` to
the community's followers, plus the object for new posts so Mastodon
shows them; updates and deletes of community content are announced too;
- top-level posts are Pages with a name (the title, or a headline from
the text); /flock counts members, /wardens lists moderators;
- a Mastodon client posts into a community by mentioning it, or into a
remote group, which sets `audience`;
- an Announce of an activity from a remote group a persona follows (Lemmy)
is followed through: the object is fetched from its own origin, kept with
its AudienceURI, and fanned out to the group's local followers; updates
are applied in place and deletes checked against the origin.
Circles stop being local-only: an undiscoverable Group actor whose follows
are all requests the owner approves; posts addressed to the circle and its
/flock and delivered to members' own inboxes, never announced, never
public; a remote member's post into the circle is accepted from members
only. SignedFetchAuthorizer serves circle posts and collections only to a
signed request from a member or a member server's instance actor - 404 for
anyone else. Circles never surface in search, lookups, mentions, account
ids or profile pages.
Federation:SecureMode requires a valid signature on every GET under
/peasants except the instance actor. Group forms take a posting policy.

- Blocks are per persona and never federate (a Block activity would tell
the other server who blocked whom): the blocked account is removed as a
follower, with a Reject{Follow} if it is remote, unfollowed, cleared from
home and notifications, and refused with Reject if it follows again.
- Mutes (optionally timed, optionally sparing notifications) and per-
persona domain blocks keep authors out of home timelines, notifications
and every status list the API returns; the boosts of a hidden author's
posts are hidden too.
- Bookmarks and pins (at most five, public or unlisted, own posts) with
their Mastodon endpoints and flags; pinned posts are the actor's
`featured` collection at /trophies, and `featuredTags` points at
/tattoos.
- Reports: /api/v1/reports stores the report and, when forwarding to a
remote account, sends Flag from the instance actor, so the reporting
persona is never named to the other server. An inbound Flag about a local
persona or its posts becomes a report; moderators list and resolve them
under /clientapi/moderator/reports.

With a token for a persona, a Mastodon client can now:
- accounts: verify/update credentials (display name, note, fields, locked,
bot, discoverable, indexable, hide collections, posting defaults; the
change federates as Update{Person}), get, lookup, statuses (paged, by
visibility to the viewer), relationships, search, follow and unfollow,
follow requests (authorize and reject answer remote followers with
Accept or Reject), remove from followers. Followers and following lists
are shown to their owner only.
- statuses: post (plain text, mentions, hashtags, replies, content
warnings, the four visibilities, Idempotency-Key), get, edit (PUT),
delete returning the source for redrafting, context, history, source,
favourite, reblog and their undos, favourited_by and reblogged_by.
- timelines: home, public (local or remote), tag; favourites;
conversations; markers.
- notifications: list with types and exclude_types, get, dismiss, clear,
unread count.
- /api/v2/search, resolving a handle or a URL to an account or a post.
Media, polls, pins, bookmarks, mutes, blocks, lists, filters, trends and
push answer empty lists or a 422 saying they are not supported yet, so
clients degrade instead of failing. Public reads work without a token.
Persona settings (locked, bot, indexable, discoverable) now also shape
the ActivityPub actor.
Fixed on the way: three conditional expressions whose `default` was the
value type's, so a missing limit became 1, a missing flag became false and
an attachment without dimensions became 0x0.
