/@user and /@user/{id} are Razor pages showing an avatar's or community's
public and unlisted posts: no scripts, a strict CSP, no-referrer, noindex,
and an alternate link to the ActivityPub document. A client asking them
for activity+json is redirected to the actor or note, and the actor and
note redirect browsers here.
NodeInfo answers 2.1 as well as 2.0 (repository, homepage, a link to
FEDERATION.md) and counts only public local posts.
FEDERATION.md (FEP-67ff) lists the protocols, FEPs, route names,
activities and the security rules a peer will notice.

Local text (Domain/Content/ContentRenderer): Markdig with raw HTML off and
autolinks, or plain text for API clients; then @user and @user@host are
resolved (locally or through WebFinger) into Mastodon's h-card markup and
#tags into hashtag links, skipping code, links and e-mail addresses. A
post stores the result, its mentions and its tags, and is delivered to
the mentioned actors and the parent's author as well as to followers.
Renderer:
- Mastodon's @context (toot, schema PropertyValue, discoverable,
indexable, blurhash, focalPoint, featured, alsoKnownAs, movedTo) and
FEP-2c59's webfinger;
- an actor's url is its HTML page, its fields are PropertyValue
attachments, published is cut to the day and indexable is false;
- a note's content is the stored rendering; a title becomes name and a
bold first line, a content warning without its own text is summarised
by the title or "Content warning"; Mention and Hashtag tags, contentMap,
updated, and to/cc by visibility.
Routes take the agreed names: /groupies, /stalking, /scribbles/{id},
/grunts/{id} (a Create resolves), /whispers/{id} for a DM's context. The
outbox is a collection with a first page, paged by max_id. A browser
asking for an actor or a note is redirected to /@user, and WebFinger's
profile-page points there.

Post gains what federation and the Mastodon API need: Visibility (Public,
Unlisted, FollowersOnly, Direct, Circle, LocalGeo), the author's account
id, to/cc, the Create's id, url, context, quote, InReplyToURI and the
parent's author, a separate SpoilerText next to the title, language,
mentions, hashtags, remote attachments (alt text, blurhash, focus, size),
reply/favourite/reblog counters, revisions, EditedAt and DeletedAt.
Direct messages are Posts with Visibility Direct and a ConversationId;
migration _005 copies DmPost rows across with their ids and fills the new
fields of existing posts. DmPost is left in place so a rollback still sees
the old messages.
Inbound:
- NoteParser reads Note, Article, Page, Question and media types: content,
then contentMap, then _misskey_content; summary as the spoiler and name
as the title; Mention and Hashtag tags; attachments; a PeerTube-style
list attribution prefers the person over the channel; quote URIs.
- Addressing classifies like Mastodon, finding followers-only by the
author's own followers URL (now stored on ForeignAvatar), not by a
"/followers" suffix.
- Create keeps a post when a local persona is addressed or mentioned, when
it replies to a local post (the parent's reply count goes up) or when a
community it follows is addressed; an unsolicited public post is not
stored. Update keeps the previous version as a revision.
The outbox and object endpoints serve only Public and Unlisted posts.

InboxService is split the way the roadmap lays out Federation/Inbox:
- InboxReceiver reads and verifies the request exactly as before, runs
the checks that need no fetch (the activity id's origin, a Follow of a
missing or local-only actor, an Undo of someone else's activity, an
embedded object attributed to someone else), queues a ProcessInbox job
and answers 202. The job's dedupe key is the activity id, so a peer that
delivers the same activity twice is processed once.
- InboxProcessor (two at a time, eight attempts) loads the verified actor
and hands the activity to the handler for its type.
- Handlers/{Follow,Undo,Create,Delete,Update}Handler are the old methods,
unchanged except that they no longer produce status codes; the JSON
helpers live in Objects/ActivityJson and the group membership helpers in
Inbox/ForeignMembers.
A slow fetch of an object or a remote actor now delays the job, not the
sender's HTTP request.

- Sign-up, login, the invitation flows and password recovery allow ten
requests a minute per client address; the inboxes give each sending
origin (the keyId's) a bucket of 300 that refills at 300 a minute, and
answer 429 beyond it, which peers retry.
- deploy.yml dumps the PrivaPub database to /var/backups before it stops
the service (the last seven are kept), and after the swap checks that
Swagger answers 404 and that the shared inbox answers junk with 400 and
an unsigned activity with 401.
- ActivityPubClient and PostBoost, never used, are gone.

S8: a direct message joins a conversation only when its participants are
exactly that conversation's members, found through a new
DmGroup.ParticipantsKey (a hash of the sorted members). A remote context
no longer decides anything: it let anyone who knew a conversation's
context post into it, and joining by context while dropping a participant
would have shown a reply to someone it was not addressed to. A context is
kept only when it is on the author's origin. Sending a DM to the same
people again reuses their conversation instead of opening a new one.
S9: Group.Kind is Circle or Community. A circle is not a federated actor:
its actor, collections, WebFinger and inbox answer 404, a remote Follow is
refused, and posts in it are IsLocalOnly - never delivered, never in an
outbox, never served. Communities keep today's behaviour until P4.
Migration _003 makes every existing group a circle, marks their posts
local-only and backfills the conversation keys.
End-to-end inbox tests sign real deliveries from a fake peer: a context
injection, a forged activity id, a note attributed to someone else, a
cross-origin object, a bad signature, junk bodies and a Follow of a circle.

Services/Federation and Controllers/ServerToServer become
Federation/{Actors,Signing,Inbox,Outbox,Rendering,Controllers}, the first step
of the roadmap's layout. No type, route or behaviour changes.
