- HttpScope (AsyncLocal) tags each outbound request with a purpose and a trigger:
- purpose is set by the caller: actor, key, object, webfinger, context, nodeinfo;
- trigger is set by the job kind, by "verify" during inbox verification, or defaults
to "request".
- FederationHttp records every JSON, media and stream fetch: status, time, bytes, hops,
and an outcome of ok, refused or failed, with a reason: disallowed, remembered,
bad-redirect, too-many-redirects, content-type, too-large, bad-json, private-address,
timeout, network, or the status. A fetch a reader caused (trigger "request") is only
counted per server per day.
- Link previews record a 'preview' event: card, no-card or failed.
- The media proxy counts cache hits.
- TrafficMeter counts the client API per endpoint group, method and status class. It
counts our served documents (actor, outbox, collection, object, activity, licence,
webfinger, nodeinfo) by kind, status and whether signed, per day and never per server,
and never names a circle's collections.

- 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.

- When a sender's key cannot be fetched because its server timed out or answered 5xx, the inbox answers 503 with
Retry-After: 300 instead of 401, so Mastodon 4.7 retries rather than switching to RFC 9421 signatures we do not
verify yet. The fetcher's failure cache now remembers whether a failure was temporary.
- Follow, Like, Block, Accept, Reject and Undo ids are deliberately not dereferenceable: serving them would publish
who follows, likes and blocks whom. They are always sent with their object embedded.

tools/pasture/run.sh starts PrivaPub, GoToSocial and Mongo on one podman network behind Caddy's internal CA, and
interop.sh drives both through their own client APIs: follows (one to a locked account), posts, CW, replies, likes,
boosts, DMs, edits, deletes and unfollow. All 25 checks pass, three fresh runs in a row.
- Federation:AcceptAnyCertificate joins the two test-network switches; startup refuses all three in Production.
- WebFinger falls back to http only when AllowPlainHttp is on.
- A bootstrap logger, so a failure before the host is built is no longer silent.
- P4 is ticked in the roadmap, with what has not been run live (Lemmy, a Mastodon circle member).

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.

S5 of the roadmap. ContentSanitizer wraps HtmlSanitizer with Mastodon's
allowlist: the inline and list tags Mastodon keeps, href/rel/class and
the list attributes, microformat and mention/hashtag/ellipsis/invisible
classes, Mastodon's link schemes, every link rel=nofollow noopener
noreferrer, relative links unlinked, headings folded to a bold paragraph,
and the contents of script, style, svg, iframe and friends dropped rather
than kept as text.
Post and DmPost gain ContentHtml (what is shown) and ContentFormat
(Markdown for local, Html for remote). Inbound Create and Update, and a
remote actor's biography, are sanitized on the way in; local posts store
their Markdig rendering. Migration _002 does the same to what is already
stored, and migrations now run at startup.

S1 and S2 of the roadmap. RemoteActorService:
- FetchObject accepts a document only when its id is the address it was
served from; a same-origin document naming another address is asked for
at that address once (how GoToSocial serves its key URIs), anything else
is dropped;
- GetActorByKeyId accepts a key only when the actor lists it, its owner is
the actor and it lives on the actor's origin, whether the keyId points at
the actor or at a key document;
- a refetch for a key or an actor happens at most once per five minutes,
so a bad signature cannot make us hammer a host;
- the cache row is written by one atomic upsert on ActorURI;
- every fetch is signed by the instance actor, never by the persona that
happened to receive the activity.
The inbox refuses an activity whose id is not on its actor's origin, and
an Undo of someone else's activity; a Create's object, an Update and a
Delete must be on the actor's origin too, and a cross-origin object is
refetched from its own origin before it is trusted.
Tests: a fake peer on two origins serves forged actors, foreign-owned keys,
cross-origin key documents, aliases and a GoToSocial-style key address
(integration, PRIVAPUB_TEST_MONGOD=1).

Infrastructure/Http adds the client the roadmap's S3 and S4 ask for:
- the connect callback resolves the name itself and refuses loopback,
private, link-local, CGNAT, documentation, multicast, ULA, NAT64, 6to4,
Teredo and IPv4-mapped/compatible forms, then connects to the vetted
address, so DNS rebinding cannot swap it afterwards;
- redirects are followed by hand, at most three, each one re-checked;
- bodies are capped at 1 MB after decompression, only JSON media types are
read, every request has a 15 s budget, and a refused URL is not asked
again for five minutes.
Actor and WebFinger fetches and inbox deliveries all use it. Test networks
can switch on Federation:AllowPrivateNetworks/AllowPlainHttp; startup
refuses both in Production.
PrivaPub.Tests (xUnit v3) starts with the address table and the fetcher's
limits against an in-process peer; build.yml and deploy.yml run it.

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.
