PrivaPub now finds CDNs three ways, best first: the address ranges the
CDNs publish (Cloudflare, Fastly, Amazon CloudFront, Bunny, Gcore,
Imperva), downloaded daily by CdnUpdater and kept in CdnRangeSet; the
CDN's fingerprint in the responses it already gets from a server
(EdgeHintsHandler on the federation client); and the networks that carry
only a CDN. The fixed ASN list is gone; ASNs shared with plain hosting
(AWS, DataPacket) no longer hide a server. A server's Geo records the
CDN, its domain and how it was found, and weekly snapshots now keep the
city and coordinates too.
Servers through time (ServerPlaces): /instances/:host/history lists a
server's weekly snapshots, a CDN-fronted server's geo names the CDN's
domain and where the server was before it (before_cdn), and
/api/privapub/v1/cdns and /cdns/:domain group servers by CDN with week
by week who joined and who left. Owner decisions recorded in ROADMAP.

- A community's announces resolve, as FEDERATION.md and ROADMAP always said Announce ids do. GroupDistributor keeps
each one it sends (GroupAnnouncement, unique by id). /grunts serves it while the post it carries is shown and 410
after, and also serves the announce-{postId} ids the group outbox lists, which now keep a stable `published`
instead of the time of the fetch.
- A persona's boost points at the boosted post: its `url` in the Mastodon API is the boosted post's page, and a browser
following the boost's id is redirected there instead of getting JSON.
- /tags/{tag}, where every Hashtag link we send points, is now a public page of this server's public posts with that
tag, with the same strict CSP and noindex as the profile pages.
- Grouped notifications (/api/v2/notifications, its unread count, a group, its accounts and dismiss). We advertise
api_versions.mastodon = 7 so clients show quotes, and clients that trust it call these; they answered 404. Likes and
boosts of one post group together, as do follows within an hour. The version string stays 4.2.0 until streaming
and Web Push exist.
- A remote account's follower, following and post counts are what its server publishes. AccountCountsJob reads its
collections' totalItems from its own origin, signed by the instance actor, at most daily and only after the account
was fetched, never when someone looks. They used to be 0.
- The other ids that do not resolve are documented as such: Update, Delete, EmojiReact, QuoteRequest and its answers,
Flag, Ignore and poll votes.
676 tests pass.

- Touches: the ledger marks a server as touched when it sends us a verified activity, when
we exchange activities with it, or when we read its actors, keys, objects or WebFinger.
It upserts RemoteInstance.Seen, FirstSeenAt and LastSeenAt at most hourly per server, and
queues one DescribeInstance a week with the same dedupe key ObjectRecords uses. Suspended
servers and pages behind link previews are never described. Migration _010 marks the
servers already known as touched, with their dates.
- InstanceDescriber.Describe(host, crawled, allowed) reads:
- NodeInfo 2.2/2.1/2.0, now with its published user counts, posts, comments,
description, languages and schema version;
- for software with a Mastodon API, /api/v2/instance falling back to v1: title,
languages, registration mode, character limit, API version, source URL.
It never keeps a contact as a field; the raw document is kept for the admin only. It
locates the server from the address our connection reached (DB-IP Lite city and ASN, the
CDN named when fronted) and writes a RemoteInstanceSnapshot per ISO week, unreachable
weeks included. A crawled server is upserted as crawled only on insert, so it never
downgrades a touched one, and robots.txt can deny any path.
- PublicGeo.Project is the only public form of a location: a CDN-fronted server shows its
CDN only, a server reporting at least ten users shows its city, coordinates and network,
any other only its country.

InteractionEvent records one interaction with a remote server: its channel (recv, in, out,
http, preview, crawl), activity and object type, outcome and reason, status, latency, wait,
bytes, attempt, audience, local actor kind, inbox, signature, features and the object's age.
IInteractionLedger.Record never blocks and never throws: events go into a bounded channel
of 10k, a full channel drops and counts, and a hosted service writes batches of up to 1000
every two seconds.
Privacy, as decided by the owner:
- no persona, root, group or activity id, inbox URL, actor URI or sender IP is stored;
- distinct accounts are counted with an HMAC keyed by a per-day salt (InteractionSalt,
upserted so restarts agree, never created for a past day);
- the local actor kind survives only on public and unlisted traffic;
- a host claimed by an unverified sender is kept only if it is already known.
Traffic caused by reading is only counted per day (InstanceDay.Reads, ServerDay). Indexes:
a 90-day TTL on events, unique day rows, and a TTL safety net on salts.

- Our public and unlisted posts state interactionPolicy.canQuote. The policy comes from the post, then the persona
(`source[quote_policy]`: public, followers or nobody; default public as the owner chose), and is always nobody for
followers-only posts and DMs.
- QuoteRequests are answered with Accept{result} naming a parrot-licence at /peasants/{name}/parrot-licences/{id}
(the route name the owner chose), or with Reject. Followers-only checks that the requester really follows.
- A licence is a QuoteAuthorization naming both posts; revoking it (POST /api/v1/statuses/:id/quotes/:quoting_id/revoke)
marks it 410, sends Delete{licence} to the quoter and the persona's followers, and revokes our own copy of the quote.
- A quote that arrives with one of our licences is accepted only if that licence is ours, unrevoked and names exactly
that quoting post. One persona quoting another gets a licence too.
- Mastodon API: quote_approval for our posts (automatic, followers, current_user), `quote_approval_policy` when posting,
PUT /api/v1/statuses/:id/interaction_policy, `source.quote_policy`.
Checked live: GoToSocial still accepts our posts with the policy stated, and leaves likes, replies and boosts open.

- 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.

A post given a latitude and longitude becomes LocalGeo: its position is
rounded to two decimals (about a kilometre) and stored as a 2dsphere
point, its radius clamped to 1-50 km, and it is local only - no Create,
no delivery, no outbox, never in the Mastodon API or on a profile page.
/clientapi/post/nearby takes the viewer's position for the query only
(it is neither stored nor logged), runs $geoNear and keeps posts within
each post's own radius, minus authors the viewer blocks or mutes. A
located post cannot be direct or in a group.

- 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.

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.

DomainBlock (domain, severity, reject-media, public and private comment)
covers the domain and its subdomains. Admins manage them under
/clientapi/admin/domainblocks/{list,insert,delete}; the set is kept in
memory, reloaded on every change and at most five minutes stale.
A suspended domain is refused by FederationHttp.IsAllowed, so nothing is
fetched from it and no job delivers to it, and the inbox drops its
activities with a 202 before fetching any key. Reject-media strips the
attachments of posts from that domain. Silence is recorded for the
timelines and notifications that arrive in P1.2.

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.

The single serial DeliveryWorker is replaced by Infrastructure/Jobs:
- Job rows are leased with one FindOneAndUpdate (oldest RunAt first, a
two-minute lease) and a reaper returns expired leases every 30 s;
- enqueueing wakes the workers, which otherwise poll every five seconds;
- delivery runs eight at a time with at most two per host, so a slow or
dead server holds two slots, not the queue;
- a failure waits n^4 + 15 + jitter seconds (Mastodon's curve) for up to
16 attempts; a 4xx other than 408/429 is final, a 429 honours
Retry-After;
- RemoteInstance is a per-host circuit breaker: ten consecutive failures
quarantine a host for an hour, doubling to a week, and its jobs wait
without spending attempts;
- a delivery is queued once per activity and inbox (unique DedupeKey), and
finished jobs expire after seven days (TTL on FinishedAt).
Migration _004 moves pending Delivery rows into jobs and marks them
abandoned, so a rollback to the old worker cannot send them twice.

Infrastructure/Data/Indexes runs at every start, after the migrations:
unique on Post/DmPost ObjectURI, ForeignAvatar ActorURI, the Follower
triple, RootToAvatar, RootUser UserName and ReservedName; plain indexes on
the lookups the services actually make (PublicKeyId, author and group
post listings, ParticipantsKey, the delivery queue).
Migration _001 runs first and removes the duplicates the races could
already have left (keeping the newest actor row, the oldest post, the
accepted follower), then fills ReservedName from every avatar and group.
ReservedName is one username space for personas, groups and the instance:
a name is reserved by an insert the unique index arbitrates, before the
avatar or group is saved, so two simultaneous sign-ups cannot both get it.
A short list of names (admin, support, abuse, postmaster, ...) is never
available.
EntityMaps.Warm touches every entity's collection one at a time before
anything else runs. MongoDB.Entities maps the Entity base class on first
touch, and two types mapped at once throw "An item with the same key has
already been added" and stay broken for the life of the process; the
parallel test run hit it, and the delivery worker racing a request could
have too.
