PrivaPub remembers a deleted remote post's id for 90 days so that a late Create cannot bring it back. Gancio numbers a
new event after the last one it keeps, so deleting its last event gives the next the same id, and that event was
dropped as deleted. A Create published after the deletion is now kept as the new post; the deleted one's own Create,
however late, still is not. Checked live: Gancio's scenario passes again (17 checks).

PeerTube puts canReply on a video whose comments wait for approval, and answers each comment with ApproveReply. A
persona's reply to such a post now waits (privapub.approval: pending), its Create going to the author alone; the
author's ApproveReply, signed by the author and naming the post answered, lets it out to its audience with
replyApproval, and RejectReply leaves it ours. A null canReply (PeerTube's open comments) says nothing; an empty one
refuses. The PeerTube scenario holds a comment for review and approves it through PeerTube's API (28 checks).

Pleroma and Akkoma send a post's earlier versions with it. A post PrivaPub first meets after its edits now has its
history, and an edit that carries them brings the versions missed in between; each is read as the post itself is. The
Akkoma scenario checks a post fetched after two edits by an account no persona follows.

Castopod announces an episode with a Note that only links to the episode's page, which serves a PodcastEpisode. PrivaPub
reads PodcastEpisode (its words in description, its sound in audio, its cover in image), and a Note that is only a link
to its author's own episode takes the episode's sound, title, cover and words, so the post plays. A server that
publishes no NodeInfo is described from NodeInfo2 (/.well-known/x-nodeinfo2), as Castopod publishes.

Forte follows a persona by its profile page (/@name, WebFinger's alias) rather than its actor's id: Follow and
Undo{Follow} now find the persona by either (it was a 404). Forte also sends an edit only added to the thread's context
(FEP-171b), under the same activity id as the post's Create: the unwrapping now tells two activities that share an id
apart by what they carry, as the inbox does, so the Update is not taken for a copy.

object is someone's Create, Update or Delete of their own object, is queued as that activity forwarded by the owner, so
it is believed on its FEP-8b32 proof or as its origin has it, and shares its job with the plain forward Hubzilla also
sends. Checked live against Hubzilla (unchanged, 20 checks).

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

Owner decision of 2026-10-06 (G-0009, FEP-400e). A persona's actor names its wall (…/graffiti, sm:wall) and, in
Smithereen's privacySettings, that its followers may write on it. A public post that is not a reply, sent with the wall
as its target by an account following the persona, is hosted: the persona is notified, it reaches the persona's and its
followers' homes, and the followers' servers and the author's are told with Add{Note}. The persona deletes it with
DELETE /api/v1/statuses/:id, which sends Remove{Note}; Smithereen deletes the post then. The wall lists the persona's
public posts that start a thread and what was written on it.
Elsewhere: an account's Add{Note} on its own wall shows the post to its followers here as on that wall (privapub.wall on
the status), and its Remove takes it away. An Add or Remove naming a collection of the account's own server PrivaPub
does not know has its document read again first, at most hourly: accounts kept before walls were read had none.
Checked live: Smithereen 40 checks (G-0009 closed); GoToSocial and Mastodon unchanged (121).

FEP-8fcf, received. When a delivery's Collection-Synchronization header digests the sender's followers on PrivaPub
otherwise than the personas following it, a job reads the list the header names (on the sender's origin, signed by the
instance actor): a follow the list leaves out ends, only when the list is the one the digest describes; a request it
lists is taken as accepted; a persona it lists that follows nothing there sends Undo{Follow}, as Mastodon does. Each
claiming delivery is compared once.

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.

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

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

Two owner decisions of 2026-10-05, both recorded in ROADMAP:
- After a verified Move the personas following the old account follow the new one, in the same lists, and a mute or
block of the old account carries over, as Mastodon does it.
- A direct message to one account on a server whose NodeInfo names Lemmy before 1.0 or Mbin goes as a ChatMessage,
the one place PrivaPub decides by a server's software (invariant 17). G-0008 is closed.
Mbin addresses its private messages to the recipient's profile page, so a Create addressed to a persona's /@name now
reaches the persona. Checked live: moves 8/8, Lemmy 0.19 30/30, Mbin 26/26 with messages both ways. The software
theory runs alone, since every test's peer shares 127.0.0.1.

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.

PrivaPub dropped Move as an unknown type and showed no `moved` on accounts.
Now a Move is believed as Mastodon believes it: the moving account sends it
about itself, and the new account, read again from its own server, names it
in alsoKnownAs (now kept on remote accounts). The old account then shows the
new one as `moved` in the Mastodon API. The personas following it keep
following it: following the new account on their behalf would tell another
server about them, so that waits for the owner.
Checked live against GoToSocial (scenarios/moves.sh: an alias, a move, 6
checks).

Mbin 1.10.1 runs in the pasture (its image, a messenger worker, a RabbitMQ
of its own, its API limits raised), and peers/mbin_token.py gets mbuser's
token through the authorization-code flow. scenarios/mbin.sh: 24 checks and
one known gap, magazines both ways, titled threads, a Note to a magazine as
a microblog post, comments, favourites and upvotes both ways, a moderator's
lock, unlock and removal, the unfollow and statistics.
What it showed:
- Mbin sends a magazine's threads to its subscribers as the author's Create,
the magazine as its audience, never announced. A post whose group is
followed here and lives on the post's own server is now kept as if
announced; the same from another server is not.
- A moderator's lock is a bare Lock (and Undo{Lock}): LockHandler takes it
from the post's own server only.
- Mbin takes private messages only as ChatMessage and its actors say
nothing about it; PrivaPub never decides by a server's software, so this
stays open as G-0008 for the owner.

PieFed 1.7.17 (dockurr's image of the release) runs in the pasture with its
Celery worker on the shared Postgres and Redis, and scenarios/piefed.sh
checks it both ways: 29 checks, communities, titled threads, comments, votes
up and down, a community poll and a vote in it, private messages, a
moderator's lock, unlock and removal, the unfollow and statistics.
What it showed:
- PieFed sends a community's announces to the inbox of the Application at a
peer's root (as Lemmy serves its site actor) and to /inbox otherwise.
PrivaPub answered 404 at its root, so every announce went to an /inbox it
does not have. The instance actor now answers at / for ActivityPub
requests, unsigned under SecureMode as at its own address.
- PieFed keeps serving a thread its moderator removed, so the removal could
never be checked against the post's origin. A community on the post's own
server now speaks for it; one elsewhere still waits for the origin to say
the post is gone.

Two owner decisions of 2026-10-05, recorded in the roadmap.
Replies passed on ("the fediverse is broken without"): a public or unlisted
reply from another server to a persona's public, unlisted or followers-only
post goes on to the persona's followers as its author's server sent it, as
Mastodon forwards it, never to the replier's own server, never for a
local-only or group post; its edit and deletion follow. Only an activity its
own actor delivered is passed on (Arrival.Raw), so nothing forwarded is
forwarded again. The town checks it as relay.reply cells (specs/relay-five:
882 checks pass); Mastodon takes a passed-on activity only with an LD
signature, which GoToSocial and Akkoma don't add, and the checker knows it.
Events: a persona joins another server's event with a Join and leaves it with
a Leave, both to the organiser only, through
POST /api/privapub/v1/statuses/:id/join|leave; the organiser's Accept or
Reject is routed by our join id and shows as privapub.event.participation.
Events by invitation or taken on another site are refused before anything
is sent. Mobilizon's scenario joins and leaves an event (28 checks) and keeps
one for decePubClient's e2e.

Three shapes Funkwhale 2.0 sends, each of which lost something:
- its Accept is named after the Follow it answers, on our origin (`…#follows/<uuid>/accept`), and was refused as off its
actor's origin, so no follow of a channel completed: an Accept or Reject whose id extends the id of the activity it
answers, on our origin, is now taken;
- a channel deletes its uploads in one Delete without an id, their ids in a list as the object's id: each is deleted;
- its NodeInfo discovery names the document under its swagger schema's URL: a link whose path names NodeInfo is taken
when no rel is known.

A remote post's canReply, canLike and canAnnounce (with the older always and approvalRequired) are kept beside
canQuote and judged for each persona: let in at once when the rule names the public, the persona, the author's
followers while it follows the author, or the accounts the author follows while the author follows it; asked first
when only the manual list names it; refused (422) otherwise. Asked first, a ReplyRequest, LikeRequest or
AnnounceRequest with the interaction as its instrument goes to the author alone, and the interaction waits
(privapub.approval: pending). The author's Accept brings an authorization, verified on the author's origin as naming the
interaction and the post; the reply then goes out with replyAuthorization, the boost with announceAuthorization, the
like with likeAuthorization. A Reject leaves the reply ours alone and takes a like or a boost back. As a third party, a
reply a policy does not let in at once is kept only with an authorization that verifies. Clients see the rules as
GoToSocial's interaction_policy.
Checked live against GoToSocial 0.22.1: the scenario's nine new checks pass (64 in all), a reply and a like approved
through its interaction requests and a boost refused.

Mobilizon's organiser sends the Create, Update and Delete of an event attributed to the group, which announces the
Event itself. PrivaPub refused the organiser's activities as misattributed (400) and kept the event through the
group's Announce, so an edit was lost and a deletion left the event in place. An object attributed to another account
of the actor's own server is now that server's to vouch for: created or edited as the server has it, under the account
it is attributed to, and deleted once the server answers 404 or 410. Attributed to an account elsewhere, it is still
refused. Checked against Mobilizon 5.2.4 in the pasture.

Lemmy keeps the ids of the activities it received and never answers one again, so resending the same Follow could not
heal a follow whose Accept it lost: the village's community follow stayed pending through two resends. Each resend is
now the same follow under its own id (<follow id>-again-<n>), and an Accept naming any of them answers the follow;
the Undo still embeds the follow, so servers match it by its actor and object. Sent this way, the stuck follow was
accepted at once.

Friendica's activity ids are uniqid(): a short prefix and the microsecond. Two of its processes answering two follows at
once gave both Accepts one id, and PrivaPub, queueing each inbox activity once per id, dropped the second as a copy:
that follow stayed pending on our side while Friendica counted the persona as a follower (seen in the town's Friendica
pair). An id that comes back carrying another type, actor or object is now queued apart; a true copy is still dropped.

A thread's server passes on what happens in it, signed with its own key: Mastodon forwards the replies to its
accounts' posts and their deletions, Friendica every activity in its threads. PrivaPub answered them 401, which also
tells a sender its signature failed. Now they get 202 and nothing in them is believed: a forwarded Create or Update is
taken as its object reads at the actor's origin, a Delete of a public or unlisted copy once that origin answers 404 or
410 (RemoteActorService.IsGone; FederationHttp remembers the status of a refusal), anything else is let go, and our own
activities coming back are ignored. A forwarded copy has its own dedupe key, so one that failed never hides the
author's own delivery.
A reply in the thread of someone followed here is kept, as Mastodon keeps them. Mastodon delivers a reply to the
followers of the account it answers; PrivaPub dropped those as unaddressed, which the pasture showed: the outsider's
reply its Mastodon scenario said was never delivered had been, and was thrown away.

server. A persona's reply in a thread of a community nobody here follows
lost its Lemmy upvotes: the relay was dropped as "not followed". Such a
relay is now taken when the vote (or its undo) is on one of our posts in a
thread rooted in that community; from any other unfollowed group it is
still dropped. For that, a post keeps the community its `audience` names
(FEP-1b12) however it arrived, fetched for a thread as well as announced.

WordPress's ActivityPub plugin (and Ghost and Fedify) sign with RFC 9421
first and fall back to draft-cavage only after a refusal, so each first
delivery cost two requests and a 401 in our statistics. Now a request
carrying Signature-Input is verified as an HTTP message signature: its
covered components (the method and our own public target, the body's
Content-Digest), its created and expires, with the actor's RSA key under
PKCS#1 v1.5 or PSS. Deliveries and signed fetches both take it; the
ledger names the scheme (rfc9421:rsa-v1_5-sha256). What PrivaPub sends
stays draft-cavage, which every server reads. Ed25519 waits for FEP-521a

Lemmy's moderation reached PrivaPub only as removals. Now a remote
community's lock and ban, relayed in its Announce, apply too:
- a lock (Announce{Lock}, or commentsEnabled false on the post) refuses
replies to the thread, ours included, until Undo{Lock}; statuses say so
in privapub.locked;
- a ban of a persona (Announce{Block} with the community as target, or the
moderator's own Block sent straight to us, which is the community's ban
and never the moderator's block of the persona) shows as blocked_by on
the community and refuses the persona's posts and replies there until
the Undo.
The Lemmy scenario's removal was an expected failure only because it gave
up before Lemmy's 30-second batch; it now waits, and checks the lock and
the ban live (Lemmy refuses a lock or an unban without a reason): 29
checks, none expected to fail. G-0003 and G-0006 are closed.

/api/v1/conversations answered one page, never unread, its read endpoint
did nothing, and DELETE was missing; each conversation cost a query per
member. Now each conversation keeps its newest post (DmGroup.LastPostId,
set as posts arrive, learnt once by migration _013) and pages by it as
Mastodon does, and each persona's ConversationState holds what it read and
what it took off its list:
- unread when someone else wrote last, after what the persona read;
- read marks it so, and writing in a conversation reads it;
- DELETE takes it off the list until a newer message brings it back.
The list reads its states, newest posts, members and accounts in a few
queries per page.

The context of a remote post showed only what PrivaPub happened to hold:
replies from servers nobody here follows were never seen, and only the
ancestors were ever fetched. Now a persona opening a public remote thread
queues FetchReplies for the post and its root, at most once an hour each.
The job reads the thread's own collection first (FEP-7888 `context`, which
Mastodon 4.5+ serves with every reply at any depth; posts or, as FEP-f228
allows, the activities that made them), and otherwise the post's `replies`
(PeerTube's `comments`) and the replies' own, two levels down. At most 5
pages and 100 posts a job, signed by the instance actor, never a persona;
each post is fetched from its own origin and stored through StoreContext,
so only public and unlisted ones are kept.

Lemmy turns an upvote into a downvote with a Dislike alone (and back with a
Like), so the like stayed counted next to the downvote. Now an account has
one vote on a post: a Dislike takes its like away, a Like its downvote.
The Lemmy scenario's relayed votes were never failing for that reason only:
Lemmy 1.0 sends what it queued every 30 seconds, and the check gave up after
30. It waits a minute now, and both votes are plain checks: 22 pass, the
moderator's removal stays an expected failure (P7).

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.

Mastodon's streaming API: /api/v1/streaming as a WebSocket (streams
subscribed in the URL or by message) and /api/v1/streaming/{stream} as
server-sent events, with health and the URL advertised. The user stream
tells posts reaching the persona's home (not those an exclusive list keeps
apart, which its list stream tells), notifications, edits and deletions;
public, hashtag and list streams tell what belongs in them. An in-process
hub carries ids only; each connection maps a post or a notification for its
own persona as it sends it, so nothing it may not see, or whose author it
blocked or muted, goes out. A deletion reaches only the streams that showed
the post. The token comes as access_token, header or WebSocket protocol.

Lemmy, PieFed and Mbin relay their members' votes, and the undoing of
them, inside the community's Announce; PrivaPub dropped them all as
unsupported (G-0003, the Lemmy scenario's expected failures). A relayed
Like, Dislike or Undo from a community a persona follows is now handled
as if its actor had sent it. The community vouches for what accounts on
its own server do and for what is done to its own posts, as Lemmy trusts
it (refetching every vote would not scale); a vote from elsewhere on
anything else is believed only once fetched from its own origin.
Moderation relayed the same way is still open.

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.

A remote post decided who here may see it by its Mention tags alone. A
followers-only post addressed in to or cc to a persona without naming
it (Akkoma's to[], or a GoToSocial edit that took the @name out while
the post stayed addressed to the persona) was hidden from that persona.
Such personas are now kept as silent mentions, as Mastodon does: they
see the post and it reaches their home, and no list shows them as
mentioned. An edit never narrows who a post was for.
The GoToSocial note that showed it is the first captured fixture
(Fixtures/gotosocial), and parses with its lone tag, to and cc.

LikeHandler.MaySee let a remote account interact with a followers-only
post only when the post named it in to, cc or its mentions. Our own
followers-only posts are addressed to the followers collection, never to
each follower, and circle posts were not considered at all, so every
like, reaction, downvote and poll vote from a follower on a
followers-only post, and from a member on a circle post, was dropped as
"not-visible". Likes, dislikes, reactions and poll votes now ask
VisibilityPolicy.RemoteCanSee: anyone for public and unlisted posts, an
addressed account for a DM, an accepted follower or an addressed account
for followers-only, a foreign member for a circle post, and never a
server's instance actor (SignedFetchAuthorizer's alias is for refetches
only).
Found by planning the town's multi-server interaction checks (G-0001).

A Note's `location` that is a Place with coordinates (Pixelfed sends
them as strings) is kept in the new Post.Place and shown as
Status.privapub.place {name, latitude, longitude, country}; an edit
replaces it. An Event's location stays its own `places`, and nothing
renders a place back out. Closes the INTEROP P2 Pixelfed location gap
and the ROADMAP long-tail item.

Owner decision 2026-10-04: fix the mismatches and every other mismatch of the same kind.
- One counting rule (Domain/Privacy/Counted), Mastodon's. It is used for a persona's statuses_count, its outbox
totalItems, NodeInfo localPosts and the instance status_count, which used to count four different things. It
counts every post that is neither deleted nor a DM, boosts included, and circle and located posts too (owner
decision). A group's count includes its remote members' posts.
- Users. Personas of banned or deleted roots no longer count, and are not found in search. NodeInfo now gives
activeMonth and activeHalfyear, and the v2 instance gives active_month instead of a constant 0.
- replies_count counts only public and unlisted replies, so it no longer tells anyone that a private reply exists.
Migration _012 recounts it.
- A remote account that deletes itself takes everything out of every count (GoneActors): its likes, downvotes,
reactions and poll votes go and their counters come back, as do its boosts', replies' and quotes' counts, and its
notifications. Lookups, account lists, search and favourited_by no longer show it. Migration _012 applies this to
accounts already gone.
- Deleting a post also deletes its pins and the local boosts of it.
- /stalking gives the same total as following_count. Members are still never listed, and hide_collections is now
always true, since the setting never did anything.
- Joining a community by invitation is following it, so /flock and /groupies agree; leaving unfollows.
- Search. Anyone may search, as on Mastodon; resolve and offset need a sign-in, offset pages, and deleted accounts
are never found.
- notifications/unread_count counts what the list shows, and the owner's follower and following lists page with
Link.
- The instance API advertises what is enforced:
- max_characters, now enforced with a 422;
- max_pinned_statuses = MaxPins;
- the media types and limits MediaService and MediaOptions accept;
- PollService's limits;
- the configured languages;
- no streaming URL until streaming exists.
domain_count counts the servers we have exchanged with; which ones stays unpublished (peers is empty).
- Routes Mastodon answers now answer instead of 404:
- directory, tags/{name}, timelines/link and identity_proofs;
- instance/languages, translation_languages, domain_blocks and privacy_policy;
- the v1 and v2 notification policy, and notification requests.
Also, from phase 3: a recovered password ends /clientapi sessions through a per-root SessionStamp claim instead of
comparing the JWT's whole-second nbf with the change time. That comparison let a token issued in the same second
survive, which made a test flaky.
671 tests pass.

The GoToSocial scenario gains 17 checks:
- alice's reply threads under gtsuser's post;
- gtsuser's edit arrives with edited_at and two history entries;
- unlike and unboost both ways;
- images with alt text both ways, theirs through our proxy;
- gtsuser follows a PrivaPub community and its announce brings the post;
- gtsuser's request to join a circle waits for the owner and is approved, and the
circle post is never served unsigned;
- a locked persona holds gtsuser's follow, rejects it, then authorizes it;
- the deploy's Mastodon smoke check passes, signed in.
54 checks passed, three runs in a row. The circle post reaching gtsuser is an expected
failure: GoToSocial keeps no post addressed only to a collection it does not know.
It found a bug. An edit made within the second the post was published carries GoToSocial's
whole-second updated == published, and IsEdit wanted strictly newer, so the edit was taken
as a refresh and lost. A first edit now also counts when it is no older and the text,
warning or title actually changed. A bare refresh still never makes a revision.

Owner decision (2026-10-03, "A remote account deletes itself"): its posts are kept but
hidden everywhere.
- Post.AuthorGone (additive bool). DeleteHandler's actor-delete branch sets it on every
post whose ActorURI is the actor (one update-many), besides dropping its follows and
timeline rows as before. RemotePosts.Build sets it on a post stored later for an
account already marked Deleted.
- One rule in VisibilityPolicy: IsShown (not deleted, author not gone), IsPublic and
CanSee exclude AuthorGone, plus Shown(post) for loaded posts.
- Lookups by id answer 404 through CanSee (statuses/:id and every sub-route, context,
bookmarks, favourites, polls, reactions, search); provenance, account statuses,
home/public/tag timelines, notifications, conversations, reblogged_by, the clientapi
home and post/DM lists, a community's outbox and our Announces filter on IsShown or
IsPublic; the Mastodon mapper never renders a hidden post or a boost of one.
Tests (30 new):
- AuthorGoneTests: the rule, the handler (posts kept, boosts included, follows and rows
gone), a post fetched after the delete, and 20 Mastodon/ActivityPub lookups over HTTP
seen before and hidden after.
- InboxGapTests: actor Update refresh (name, sanitised summary, key rotation in place
and to a new key id) even with an older `updated`; Undo{Follow} by activity id and by
object; Reject of our QuoteRequest (and a stranger's ignored); group-wrapped
Announce{Like} and Announce{Undo{Like}}; a locked persona's pending follow,
FollowRequest notification, and Decide accepting and rejecting with the original Follow.
- JobHandlerTests: AncestorsJobHandler up to its depth limit; PollRefreshJob and
PollCloseJob (local and remote polls); InstanceDescriber from a peer's NodeInfo and
the weekly dedupe through ObjectRecords; LinkPreviews for public posts only;
DeliveryJobHandler outcomes (2xx, 404/410, 429/503 with Retry-After in seconds and as
a date, 5xx) and a signature and Digest the peer can verify; MediaJanitor.Sweep;
OAuthPruner.Prune.
- MigrationTests: _003, _004, _006 and _007 on seeded rows.
- PublicPagesTests: /@user and /@user/{id} (visibility, junk ids, exact CSP,
Referrer-Policy and nosniff), circle 404, community page, the instance actor,
ActivityPub redirects, and markup escaped in posts, titles and bios.
Production changes besides the rule:
- LinkPreviews.Handle re-checks that a post is still shown and public (the rule
Wanted applies) before fetching anything; before, only enqueueing checked it.
- The legacy /clientapi post and DM lists no longer return soft-deleted posts.
- MediaJanitor.Sweep and OAuthPruner.Prune are the loop bodies, now public and tested.
- InstanceDescriber.Address: a protected virtual identity seam so a test can point
the https NodeInfo addresses at a plain-http peer; production behaviour unchanged.

- A fetched ObjectRecord no longer wears the signature, key, signed headers and @context
of the activity that caused the fetch, and its ReceivedAt is the fetch's own time. Its
activity fields now name the trigger. Provenance answers signature null and
fetchedBy "instance-actor". Migration _008 clears the old fetched records.
- ObjectRecords store their ObjectFeatures extensions and context namespaces (migration
_009 fills older records in batches), so statistics can count them. Provenance reads the
stored lists.
- ForeignAvatar.Features records what an actor document uses (ActorFeatures): featured,
shared inbox, FEP-521a, FEP-8b32, identity proofs, Misskey fields, indexable,
undiscoverable, locked, key size, and more.
- RemoteEdits.Apply and RemoteDeletes.Remove are shared by the Update, Delete and Announce
handlers. A community-wrapped Update is now an edit only when newer, refreshes polls
and media otherwise, revises the ObjectRecord and re-resolves quotes. A
community-wrapped Delete now tombstones the object, removes its ObjectRecord, reblogs
and timeline rows, and lowers the reply count. Any deleted quoting post lowers the
quoted post's quote count.

- 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.

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.

Arrival carries a verdict that handlers set with one line before an existing return
(Arrival.Drop, Reject, Accept, About), so no handler signature changes. InboxProcessor
records it as an 'in' event, with the time taken, the wait since the inbox accepted it, the
attempt, the audience (from the post's visibility, or else the activity's addressing), the
local actor kind, the object's age for updates, deletes and reactions, and the FEP features
of a delivered object. It also records types nothing handles (unknown-type), actors that
cannot be loaded (deferred) and handler failures.
Drop reasons: fetch-failed, unparseable, misattributed, duplicate, deleted, not-addressed,
not-followed, not-public, not-visible, not-deleted, unknown-object, unknown-recipient,
cross-origin, unsupported. Accepted sub-reasons: stored, poll-vote, edit, refresh,
actor-refresh, actor-delete, removed, tombstone-only, auto-accepted, pending,
follow-answer, quote-answer, quote-granted, undone, reaction, reported. Rejected: blocked,
ignored, quote-refused.
A circle's traffic is private and kindless, and a stranger posting into one is just
not-addressed, so the event store cannot reveal a circle.

InboxReceiver records each answer once, in a finally, with a reason: too-large, not-json,
not-activity, missing-type-or-actor, no-signature, the signature check's own codes
(headers-unsigned, digest-mismatch, header-unreadable, date-skew, expired,
algorithm-unsupported), signature-invalid, actor-not-key-owner, key-unavailable,
id-cross-origin, undo-foreign, misattributed, unknown-recipient, and for 202s queued,
duplicate, suspended or self-delete-unknown-key. Each event carries the activity and object
type, the inbox, the signature scheme, the bytes and the time taken. A 404 for an unknown
/mouth and a rate-limited inbox (429, from OnRejected) are recorded too.
Until the signature verifies, the host is only claimed, so it is kept only if the server is
already known. A suspended server is recorded under its own name.

- 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.

- 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.
