- Received quotes: read from `quote`, `quoteUrl`, `quoteUri`, `_misskey_quote` or a FEP-e232 Link tag; the quoted post
is fetched once; a quoteAuthorization stamp is verified field by field on the quoted author's origin; a consent
quote without a stamp is pending; an older-key quote of a public post is shown; Delete of a stamp revokes. Counts
and a `quote` notification follow the accepted state. The `quote-inline` fallback survives sanitising and is removed
from content when the real quote is shown.
- Personas quote through `quoted_status_id`: posts that state a quote policy get a QuoteRequest and stay pending until
an Accept brings a stamp we can verify, then an Update adds quoteAuthorization; posts that state none are quoted
the older way, without `quote`; another persona's posts cannot be quoted yet (we issue no stamps). Quoting posts
are delivered to the quoted author too.
- Mastodon API: Status.quote (with the quoted status one level deep), quotes_count, quote_approval from the remote
policy, GET /api/v1/statuses/:id/quotes, `quote` notifications, and api_versions.mastodon = 7.
Checked live: GoToSocial's author-only quote policy is respected.

- A public post that links to a page gets a preview card: from the post's own data first (FEP-8967 Link preview, the
object's image, title and summary); otherwise the server reads the page once, 0-60 s after the post arrives, never
when someone reads it. OpenGraph and Twitter tags give title, description and image; one LinkPreview per address
is cached for 7 days and shared by the whole server, so a fetch never points at a persona.
- Lemmy link posts, which carry no title or description, get them filled in.
- The page fetch uses the guarded client (public addresses, three redirects, HTML only, first 512 KB).
- Federation:FetchLinkPreviews switches page fetching off.
- Local public posts get cards too.
Checked live: a link to a GoToSocial profile page becomes a card with its title, description and proxied image.

- Incoming reactions in all three shapes: Misskey and Sharkey Likes carrying an emoji (`content` or
`_misskey_reaction`), Pleroma, Akkoma and Iceshrimp.NET EmojiReacts, and their Undo. Unicode reactions are one
grapheme; custom ones need their Emoji tag and keep its image; `:name@host:` is read as `name`. A Like whose
content is a heart stays a favourite.
- Reactions are kept per account and emoji on our posts and on remote ones we hold, and the author of a local post
gets a `pleroma:emoji_reaction` notification with the emoji.
- Personas react through Pleroma's API (PUT/DELETE /api/v1/pleroma/statuses/:id/reactions/:emoji, GET for the list),
which sends an EmojiReact (or its Undo) to the post's author.
- Statuses carry `emoji_reactions` (read by Phanpy) and `pleroma.emoji_reactions`, with counts and whether the viewer
reacted.

- Custom emoji (Emoji tags) on posts, display names, bios and profile fields, at most 64 per object, proxied, in
Status.emojis and Account.emojis.
- Remote profiles keep their header, profile fields, locked flag, published date, movedTo, indexable, memorial and
image descriptions (a locked GoToSocial account no longer shows as open).
- Polls: incoming Questions (Mastodon, Misskey, Pleroma, GoToSocial shapes) with counts, voters, end and closed;
our own polls from the Mastodon API go out as Questions; votes in are counted once per voter and never become
replies; personas vote on other servers' polls with one Note per choice; counts refresh with an Update at most every
three minutes; a poll closes on time and tells its voters and its author. GET /api/v1/polls/:id and POST
/api/v1/polls/:id/votes.
- An Update without a newer `updated` only refreshes poll, video, audio and event details and leaves no revision.
Checked live against GoToSocial: each side's poll reaches the other as a poll and each side's vote is counted.

- 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.

- ObjectRecord, one per stored remote object: the raw JSON (up to 256 KB, always hashed), delivered or fetched,
refetched from origin or not, the activity that brought it (or caused the fetch), shared or personal inbox, the
signature's key, algorithm and signed headers, received time, published and updated, the delivering activity's
@context, and up to ten later revisions from Update.
- Delivery details travel from InboxReceiver through the inbox job to the handlers as Arrival.Current.
- A host is described from its NodeInfo when we first hear from it, at most weekly (DescribeInstance job), never when
someone opens the details view.
- GET /api/privapub/v1/statuses/:id/provenance and /api/privapub/v1/instances/:host, with the extensions an object
used detected from its raw form (044f quotes, interaction policies, contexts, proofs, Misskey fields, MFM, FEP-8967
links, emoji, polls, language maps, url variants, Markdown content).
Checked live: a GoToSocial reply shows as delivered to the shared inbox, signed hs2019 with GoToSocial's fragment-less
key id, with its interaction policy detected, and gts.test is described as gotosocial 0.22.1.

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.

- /api/v1/media and /api/v2/media (and GET/PUT /api/v1/media/:id):
images go through libvips (NetVips, its native build bundled):
autorotated, every kind of metadata dropped (EXIF, GPS, XMP, IPTC,
comments), capped at 4096 px, with a 640 px preview and a blurhash
(own encoder, the reference algorithm); animated GIFs are re-encoded;
video and audio are remuxed by ffmpeg with -map_metadata -1, never
re-encoded, and a video gets a still preview. Files get random names
under /var/lib/privapub/media, outside the web root deploys replace, and
are served at /media/files with nosniff and a sandbox CSP.
- media_ids on create and edit (four at most, the persona's own, each used
once); notes carry them as Document attachments with alt text, blurhash,
focalPoint and size; inbound attachments were already kept.
- avatar and header uploads in update_credentials, cropped to 400x400 and
1500x500, federated with Update{Person}.
- Remote media reaches clients only through /media/proxy/{hmac}/{url},
fetched by the guarded client (no SVG, 40 MB cap) and cached outside the
served root, trimmed to 5 GB; foreign avatars and headers use it too, so
a client never contacts another server.
- MediaJanitor deletes uploads left unattached for a day.
- nginx accepts 100 MB bodies on the upload endpoints only (applied on Max).

- 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.

Domain/Statuses/StatusService takes a persona, not a root, and is what
/clientapi and the Mastodon API share:
- Publish renders Markdown (clientapi) or plain text (Mastodon clients),
checks the persona may see the post it replies to, opens or reuses the
conversation for a direct post from its recipients and mentions, fans
out and hands the Create to the outbox;
- Edit keeps a revision and sends Update{Note}; Remove soft-deletes and
returns the post, so a client can delete and redraft;
- Favourite and Reblog work on anything the persona can see and send Like,
Announce and their Undo to the author (and, for boosts, to followers);
boosts are refused for anything but public and unlisted posts.
PostsService is now the clientapi wrapper that checks the root owns the
persona. A persona's own boost is a local row: the outbox renders it as
Announce, /grunts/announce-{id} resolves, and object endpoints, profile
pages and NodeInfo skip it. ContentFormat gains Plain.

- Like: a Favourite per account and post (unique), the post's counter, a
Favourite notification for a local author; only on posts the liker
could see (public and unlisted, or followers-only and direct when they
were addressed).
- Announce: the original is always refetched from its own origin (or is
ours), and must be public or unlisted. A boost of a local post counts
and notifies; a boost by an account a persona follows is stored as a
reblog row and fanned out to its followers' home timelines (as a reblog,
where reblogs are wanted). A boost by a stranger of a stranger's post is
ignored. FEP-1b12 group announces of activities wait for P4.
- Undo of a Like or an Announce reverses each of them; an Undo naming only
an id is matched against follows, likes and boosts in turn.

Fanout writes a TimelineEntry for every persona a post should reach: the
author, local followers of a local author, local followers of a remote one,
the members of a direct conversation or a circle. Mastodon's home rules
apply when it is written: a reply shows only to followers of both sides
(or to the one replied to), a reblog only where reblogs are wanted. A
mention of a local persona becomes a Mention notification.
Inbound posts are now also kept when a persona follows their author.
RemotePosts holds what CreateHandler and backfill share: building a Post
from a note, and fetching a public parent the first time a reply to it
arrives, so its author is known (a reply to an unknown or non-public
parent stays out of home timelines). Each fetched ancestor queues a
FetchAncestors job for the next one, up to ten deep.
/clientapi/timeline/home and /clientapi/notifications (with
/notifications/read) page by max_id for the persona's own root only.

OutboxPublisher works out who a post goes to, Mastodon's way: followers'
shared inboxes for public, unlisted and followers-only; every mentioned
remote account's own inbox; the recipients only for direct; the parent's
author for a reply; a community's followers for a post in it; nobody for
a circle. Creates, updates and deletes all use it.
- Local posts take a visibility (public, unlisted, followers-only) and a
spoiler text next to the content-warning flag.
- /clientapi/post/update keeps the previous version as a revision,
re-renders, and sends Update{Note} with `updated` to the same to/cc.
- Deleting is now soft: the content, title, spoiler, media and revisions
are cleared, timeline entries removed, the parent's reply count goes
down, Delete goes to the stored audience, and the object answers 410
with a Tombstone instead of 404.
- Editing a persona's profile sends Update{Person} to its followers.

Following records what a local persona follows, local or remote, with
its state and the Follow activity's id. FollowService (behind
/clientapi/follow, /clientapi/unfollow and /clientapi/following):
- resolves @user, user@host or an actor URI;
- a local account is followed in-process: accepted unless it approves
followers by hand, a Follower row on the other side, a community gains
the persona as a member, and a Follow or FollowRequest notification;
- a remote account gets a Follow signed by the persona, at
/grunts/follow-{id}, and stays Requested until an Accept;
- unfollowing deletes the rows, or sends Undo{Follow} to a remote account.
Inbound Accept and Reject are matched to the Follow by its id (or, for an
embedded Follow without one, by its actor), and only from the account that
was followed. A remote Follow now notifies the persona too.
Notification is the per-persona record P1.2 builds on, deduplicated by
type, persona, sender and post. TimelineEntry and Favourite are created
with their indexes for the next commits.
