Votes out. A persona's downvote is a Dislike (POST /api/v1/statuses/:id/downvote and /undownvote, the viewer's own as
privapub.votes.downvoted). One vote a post: a changed vote is sent as the new vote alone, as Lemmy sends one, since an
Undo of the old one beside it could arrive after it and take the new one away; Undo goes only when a vote is taken back.
A vote on a post in a remote community goes to the community, which counts it, and to the author only when on another
server: one copy a server, since PieFed drops a second copy of an activity it has just seen. Mbin keeps a favourite
apart from a vote, so there a favourite stays after a switch to a downvote.
Feeds followed (owner decision 2026-10-07: through the server). Following a feed (Lemmy's multi-community, PieFed's feed)
keeps a FeedSubscription for the persona and nothing else; the new Service privapub_feeds (LocalActorKind.Reader,
reserved by migration _017) follows every community of the feeds read here, reconciled when a persona follows or leaves
one, when a feed's list is read again (kept as it was when it cannot be read) and every six hours. Its Following rows
carry FollowerKind, so nobody's home gets what it brings in and its unanswered follows are sent again as its own. The
persona reads GET /api/v1/timelines/feed/:id (the feed's threads, ours included) and lists its feeds at GET /api/v1/feeds.
Checked in the pasture, every scenario: 873 pass. The 14 failures are Hubzilla's (identical on the previous commit:
Hubzilla no longer answers a follow in this pasture since its restore) and two activities Smithereen never sent;
followsync passes once the pasture's restore is older than the 14-day pause. Live: alice's downvotes count as downvotes
on Lemmy 1.0 and PieFed, replacing her upvote; Lemmy 1.0 and PieFed take privapub_feeds' follows and their threads reach
the feed timelines.

What a restore lost of either side is not the other server's to mend: for RestoreRecord.FollowersGrace (14 days)
deliveries carry no Collection-Synchronization header, and a follow only the remote remembers is adopted rather than
undone. Without a restore nothing changes; the interop sweep (gts, mastodon, misskey, sharkey, akkoma, pixelfed,
smithereen, followsync, pins, moves) passed, Smithereen's poll check on a second run.

Lemmy takes a report only from a person or a service, about one post or comment, addressed to its community, and it
answered PrivaPub's Flag (the instance actor's, an Application, with no `to` and the account and posts as its object)
400. A report of a post or comment in a community on a server whose NodeInfo names Lemmy now leaves from
`privapub_reports`, a Service with its own key that names nobody: one Flag per post, `to` the community (its own
audience, else its thread's), with the persona's words, or the category, in `summary` and `content`, sent to the
community's inbox. This is the second exception to "a server's software is for display" (owner decision 2026-10-06,
`ReportService.ServiceReportTakers`). Every other server keeps the instance actor's report. An account alone is not
reported to Lemmy, which takes no such report, and `forwarded` now says whether anything left.
The reporter is read unsigned in SecureMode and answers WebFinger like the instance actor. Nobody follows or mentions
it, the Mastodon API has no account for it, and a migration reserves its name. Checked live: Lemmy 1.0 and 0.19 keep the
reports of a thread and of a comment, with alice's words, from "Reports from privapub.test", and none names her (69
checks). A sweep of every scenario with this and the next commit: 876 checks pass; Ghost's Network feed listed alice's
post too late once, and Ghost passes alone.

Lemmy keeps its user's post in a community pending until the community announces it back. A community hosted here
announced only to its followers, so a post from a server where nobody follows the community stayed pending there; the
author's own server (its shared inbox) now gets the announces too. INTEROP records, confirmed live, why Lemmy refuses
our Flags (an Application reporter, no `to`, an array object). FEDERATION.md's custom emoji line is put back before the
replies paragraph.

The proof term added with integrity proofs had a @graph container, which only JSON-LD 1.1 knows: Smithereen's reader
refused every document carrying our context with a 500. Those 500s, retried, then put Smithereen's host in quarantine
for an hour, and every delivery to it waited. Proofs are canonicalised as JSON (JCS), so the term loses nothing as a
plain id; a test keeps every term within 1.0. Only an unreachable host, a timeout or a gateway's 502, 503 or 504 now
counts against a host: a 500 is the server failing on that one activity, retried on its own.

FEP-521a and FEP-8b32. Every persona has an Ed25519 key of its own (Avatar.SigningKey; migration 014 gives the earlier
ones theirs), named in its actor's assertionMethod as a Multikey, the terms defined in the actor's own context. A
persona's activity going to a relay carries an eddsa-jcs-2022 proof (JSON canonicalised by RFC 8785, Jcs), so what
Activity-Relay forwards reaches Mastodon, which verifies it with its own code. Nothing else carries one: Mitra takes a
proof over the HTTP signature and refuses one by a key it has not read, without reading the actor again. Received: an
actor's own Multikeys are kept, and a forwarded activity whose proof one of them verifies is taken as it came instead of
being read again from its origin.
Discovery: WebFinger for the server's origin links its instance actor (FEP-d556), NodeInfo links it as the application
actor (FEP-2677), and actors name RFC 9421 under implements (FEP-844e).
Checked live: relay 16 (Activity-Relay's forward of alice's post reaches Mastodon), Mitra, GoToSocial and Mastodon
unchanged (165 in all).

Owner decision of 2026-10-06 (FEP-8fcf). A persona's delivery addressed to its followers carries a signed
Collection-Synchronization header naming its followers, its roll-call (…/groupies/roll-call) and the digest of its
accepted followers on the receiving server only. The roll-call answers a signed request with the persona's followers
on the signer's server and nobody else's.
Mastodon gives every Undo{Follow} it sends after reading a roll-call the same id (…#follows//undo), so a second one
looked like a copy: an Undo of a Follow that comes again while the follow it ends exists again is now kept once per
follow.
Checked live (scenarios/followsync.sh): Mastodon drops a follow PrivaPub lost, and undoes one it lost itself.

The owner decided four gated questions, now in ROADMAP: personas publish a wall (G-0009), their public posts go to the
relays PrivaPub subscribes to, public threads publish their replies and context, and FEP-8fcf follower digests are sent.
The first is in: a persona's own public post outside any group, its edit and its deletion also go to the relays that
accepted us, as Mastodon sends them; nothing less public, and no boost. Checked live (scenarios/relay.sh, 15 checks):
the post reaches Activity-Relay, and Mastodon through aode-relay's announce. Mastodon drops what Activity-Relay forwards
without an LD signature or FEP-8b32 proof, which PrivaPub does not add yet.

An activity now goes once to each server, to its shared inbox when it has one, for the accounts a post names, answers
or quotes as for its followers, as Mastodon delivers (a circle post excepted: each member's copy names that member).
BookWyrm took the same post twice when one copy reached its shared inbox and another the named account's inbox at once.
SharedInboxTests checks a reply to a follower's post goes once.
BookWyrm joins the pasture (peers/bookwyrm.sh: its image on the shared Postgres and Redis, gunicorn and a Celery worker,
its user, book and statuses made in its Django shell). scenarios/bookwyrm.sh: follows both ways, a review, a comment and
a quotation reaching alice as BookWyrm's pure posts, her like, boost and reply landing there, her post naming bwuser and
bwuser's like and reply, a deletion, the unfollow and statistics: 20 checks. GoToSocial (64), Mastodon (57) and Misskey
(35) still pass.

An account elsewhere that pins or unpins one of its posts (Add or Remove on its `featured`) now shows those pins on its
profile here (`pinned=true`), in its order and its public posts only; a community's announce of a moderator's Add does
the same for the community. The `featured` collection itself is read with the account's counts, at most once a day, so
pins made before PrivaPub ever saw an account show too. Any other target (Smithereen's wall, a community's moderators)
is dropped. A persona's pin and unpin go to the post's audience as Add and Remove on /trophies, as Mastodon sends them.
Checked live against Mastodon (scenarios/pins.sh, 8 checks). The town's checker learnt three peer rules from the
village: Misskey and Sharkey keep a forwarded reply only with its author's LD signature (only Mastodon signs), they
count no renote by a bot, and Mastodon never sees a Lemmy vote on a post in a community. The village of 2026-10-05
checks clean, 2454 of 2454.

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 comment in a community was announced only as Announce{Create}, which
Akkoma, Mastodon and Misskey drop: their members never saw it (the village
found Akkoma's missing). A comment is now also announced as itself, as a
new post already was; Lemmy answers that form 400, harmlessly. Nothing is
decided by the follower's software.
The town's checker expects a followers-only quote to stay with the
followers, and G-0003 covers only Lemmy-hosted communities (their relayed
moderation), since relayed likes count.

A server can take a Follow with 202 and drop it afterwards, as Pleroma does
while it cannot fetch our actor; the request then stayed pending for good.
Following again now sends an unanswered request once more, the same
activity, at most once an hour (a delivery's `again` key).
accounts/search takes following=true: only accounts the persona follows,
by the start of their name, display name or server, never resolved; a
client fills a list with it. "already take" becomes "already taken".

Inbound Block was dropped as an unknown type (the pasture's last
Mastodon expected failure, G-0002). Now, as Mastodon does it: the
follows between the blocker and the persona end here too (nothing is
sent back; the blocker already ended its side), the blocker's posts and
notifications are hidden from the persona and kept out of its home, the
persona's posts are no longer addressed to the blocker by mention or
reply, and the relationship says blocked_by. Undo{Block} lifts it. The
block is kept in BlockedBy, unique per persona and blocker.
The Mastodon scenario checks blocked_by instead of expecting a failure.

Mastodon answers 422 when two first contacts from one actor race to
create its account (ActiveRecord::RecordInvalid on the unique uri), and
409 while another worker holds its lock. A persona that followed two
Mastodon accounts at once had one Follow refused that way; the job died
on its first attempt and the persona waited on "requested" forever.
Both answers are now retried twice on the usual backoff before they
count as refusals.
Found by the town (a village of 23 accounts on seven servers).

- 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.

Owner decision 2026-10-04: fix the account privacy findings.
- Sign-in. Every failure answers "That username and password do not match." after the same work: an unknown login
is hashed against a decoy, and the comparison is constant-time. "Banned" is told only to someone who gave the right
password. This covers /clientapi/user/login, /invitation/login and /oauth/login.
- Recovery.
- Every request answers the same sentence and queues a SendRecovery job, whether or not the account exists or has an
email. The lookup, the code and SMTP move to RecoveryJob, so neither the answer nor its timing says anything.
- Codes are kept only as a SHA-256 hash, for one hour. Migration _011 drops the plaintext ones, which never expired.
- A recovered password ends every session of the root. RootSessions sets CredentialsChangedAt, which JwtEvents
checks against the JWT's issue time, now stamped as nbf, and revokes each persona's OAuth tokens and authorizations.
- Deleting a root (RootRemoval: the admin route, or the restored self-delete at /clientapi/user/delete, which asks for
the password).
- Its sessions end.
- Each persona and each group it owns sends Delete{Actor} to its followers, its members and the accounts it follows.
- The personas' posts are emptied.
- /peasants/{name} answers 410 with a Tombstone (formerType Person or Group), as do its inbox and WebFinger, through
LocalActorService.Gone. The names stay reserved.
- The root keeps only a unique `deleted-{id}` name; the second deletion on an instance used to collide on
"Deleted user".
Also, from phase 2's pasture: GoToSocial files a circle post like a DM and shows it only to accounts it mentions. Each
member's copy, and a member's refetch, now also mentions that member silently. The GoToSocial scenario checks circle
posts in conversations, like DMs, and they pass there now, as on Mastodon.
657 tests pass.

Circles (owner decision 2026-10-04: fix them for compatibility):
- Mastodon 4.7 and GoToSocial drop a post that names none of their accounts, and a circle post named only the circle
and its /flock. OutboxPublisher.Publish now sends each member a copy that also names that member in `cc`, on the
activity and on the object, and names no other member. The Create, every Update (edit, poll, quote approval, policy,
through the new PublishUpdate) and the Delete (StatusService.Remove now uses Publish) all go that way.
- UpdateOf renders with the post's group, so an Update keeps a circle post's `audience` and a community post's `Page`
and title.
- A reply to a circle post stays in the circle, whichever client wrote it.
- A circle post can no longer quote a post that needs permission: asking would show the circle post to its author.
Posts that are not public, on refetch (SignedFetchAuthorizer.MayRead):
- Followers-only, direct and circle posts are served to a signed request from someone they were for, or from the
instance actor of a server where one of them lives. That is a follower or an addressed account, an addressed
account, or a member. Everyone else still gets 404.
- Once deleted they answer those readers 410. Mastodon deletes its copy when a refetch answers 404.
- A circle refetch names the requesting member, or the members on the requesting server, as the delivered copy did.
- /grunts/create-{id} serves the same.
- /peasants/{name}/whispers/{id}, a DM's `context`, was never routed. It is now the conversation's posts, for its
participants only.
SecureMode lets browsers through to the redirect to the public page, instead of answering them 401.
653 tests pass.

peers/lemmy.sh runs the Lemmy 1.0.0-beta.2 backend on the shared Postgres. It trusts
Caddy's CA through SSL_CERT_FILE and reaches the pasture through
DANGER_FEDERATION_ALLOW_LOCAL_IP. Lemmy 0.19 cannot join: its rustls trusts only its
bundled roots. LEMMY_LOG sets RUST_LOG.
scenarios/lemmy.sh drives Lemmy through its v4 API. 20 checks pass, three runs in a row:
- communities both ways;
- a titled thread each way, and alice's mention of a Lemmy community becoming a thread
there;
- the Lemmy community's announce reaching alice's home;
- comments both ways and alice's like as an upvote;
- private messages both ways;
- statistics.
Two expected failures: votes, which Lemmy sends only through the community as
Announce{Like|Dislike}, and a moderator's removal. Both belong to P7.
What it showed, in docs/INTEROP.md:
- Lemmy 1.0 keeps its user's thread in a remote community pending until the community
announces it back. It clears the flag before answering that echo 400 ("Object is not
remote"). Leaving the author's server out of the Announce, as tried here, left every
such thread pending, so GroupDistributor now says why the echo stays.
- Every bare Announce{object} is answered 400, as Lemmy answers its own compatibility
Announce(Page).

DeliveryJobHandler records each attempt as an 'out' event: the activity, object type and
audience read from the body (ActivityShape, shared with the inbox side), the receiving
server, the status, the time the POST took, the wait since it was queued, the bytes, the
attempt number and the signer's kind (none for circles or private traffic). The outcome is
ok, deferred (429 or 503 with Retry-After, or an open breaker: host-unavailable), retry
(5xx, 408, timeout, network), or dead: another 4xx, private-address, not-deliverable,
signer-gone, or a retry at the last attempt. Until now none of this outlived the job's
seven-day TTL, and the last error was overwritten on success.

- 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.

- 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.

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.

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.

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/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.
