Federation:Relays names relays by their actor (or inbox) address; the instance actor follows Public at each, as Mastodon
subscribes, a minute after start and every six hours (asked again a day after no answer or a refusal, undone when a
relay is no longer named). What an accepted relay passes on comes to the federated timeline and nobody's home: a public
post it forwards (Activity-Relay), read again from its origin like any forwarded post, and a post it announces
(aode-relay), kept as its author's and never as the relay's boost. Nothing of a persona's is sent to a relay; sending
public posts there waits for the owner.
The pasture gains both relays (peers/relay.sh, peers/aoderelay.sh) and scenarios/relay.sh, 13 checks. The village
backlog is clean: 2574 checks pass, one known gap (Misskey's).

tools/pasture/flood/flood.cs answers as twenty fake servers (flood1..20.test)
and sends signed Creates, Likes and Follows at a set rate; load.sh measures
the answers, the queue's wait and processing times, its drain and a persona's
home timeline meanwhile (docs/LOAD.md has the method and the runs).
What the runs found:
- Every unique index was partial on $type: "string", which MongoDB never uses
for an equality lookup, so every post by ObjectURI, actor by ActorURI,
deleted object, domain block, remote instance and the rest was a
collection scan (280 ms a post lookup at 30 000 posts). They are partial on
$gt: "" now, which an equality on a string implies; MongoDB.Entities
rebuilds them in place at the next start.
- Two inbox workers capped intake near 110 activities a second:
Federation:InboxConcurrency and DeliveryConcurrency (default 8) set them.
- The indexes the plan listed as missing: a post's boosts and replies, a
persona's boosts, who follows an actor, timeline rows by author, a post's
likes and pins.
At 300 activities a second (200 let through, the rest 429 by the per-origin
limit) the queue wait went from 29 s to 6 ms at p50; with the limits lifted
PrivaPub processes about 900 a second, each in under 10 ms, and the home
timeline stays under 20 ms.

- 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.

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).

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.

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.
