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).

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.

Off by default (Statistics:Crawler:Enabled), as the owner decided. When it is on:
- CrawlPlan runs hourly, from StatisticsSchedule. It inserts the configured seeds and
queues up to HostsPerHour servers whose last visit is older than RevisitDays, are not
paused by the breaker and are not domain-blocked, spread across the hour.
- CrawlInstance visits one server at a time as
"PrivaPub-Stargazer/<ref> (+<base>/stargazing)":
- it reads robots.txt (RFC 9309: its own group first, then PrivaPub, then *; longest
rule wins; a 4xx allows everything; a 5xx or no answer keeps it out);
- it describes servers that only crawling ever found, through
InstanceDescriber.Describe with robots.txt as the path filter;
- it reads /api/v1/instance/peers through the new GetStringArray, which keeps what it
read from the first 1 MB instead of refusing a large list;
- it adds the names a server could ever be reached at as "crawled": DNS only,
punycode, no addresses, ports or hidden services, and the reserved test names only on
a test network. Never more than MaxNewHostsPerCrawl per visit or MaxHosts in all, and
never over a touched server.
- It reads nothing but robots.txt, NodeInfo, the instance API and the peers list.
IFederationHttp.GetText serves robots.txt, and HttpScope.Crawl carries the
User-Agent.
- /stargazing explains all this and how to keep the crawler out, says whether it is on,
and credits DB-IP. GET /clientapi/admin/statistics/crawler shows the frontier.

- 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.

88 integration tests drive the Mastodon client API through the whole server
(PrivaPubHost), with remote actors on an in-process Peer and deliveries read
from the job queue. Helpers live in Support/Host/MastodonHelpers.cs.
Coverage:
- Accounts: verify_credentials (no root id or login name); update_credentials
with indexed and array fields_attributes (form and JSON), source[*],
quote_policy, locked/bot, avatar and header uploads resized and stripped of
EXIF and XMP; lookup (local, @domain, remote; a circle, the instance actor
and a circle's id answer 404); search with and without resolve (only a
signed-in persona resolves, the Peer is untouched otherwise), by post and
actor address, hashtags, undiscoverable personas; account statuses with
pinned, exclude_replies, exclude_reblogs, only_media, tagged and Link paging
both ways; followers-only posts for followers (local and remote authors);
community accounts; followers/following only to their owner; follow (open,
locked, remote Follow delivery), unfollow and Undo; follow requests from
local and remote followers answered with the original Follow;
remove_from_followers; blocks with Reject and Block/Undo deliveries; mutes
with duration and the notifications choice, never federated; domain blocks;
relationships with junk ids; a banned login's tokens; reports forwarded as a
Flag from the instance actor only; account stub routes.
- Statuses: each visibility's to/cc as delivered; CW as summary; replies to
local and remote posts (mention, inReplyTo, the author's inbox); polls and
votes (local, and remote votes only to the author without published); media
attached only by its owner; quotes, the quotes list and revocation; edit
history, source and the Update delivery; delete for redraft, the 410
Tombstone and the Delete delivery; favourite/reblog counts with Like,
Announce and their Undos; favourited_by, reblogged_by; bookmarks; pins;
interaction_policy matching canQuote in the note and in the Update;
strangers get 404 for followers-only and direct posts; a located post is
unreachable by id for anyone else on every route; statuses?id[];
Idempotency-Key; scopes; deleting a reblog.
- Timelines: home paging with max_id, since_id and min_id; public local and
remote; tag (anonymous); list stub; favourites; conversations and read;
markers; notifications with types[], exclude_types[], account_id, paging,
get, dismiss, clear and unread_count.
- Instance: v1 and v2 (4.2.0 (compatible; PrivaPub)), peers, activity, rules,
extended_description, apps and every stub route.
- Media: v1 and v2 uploads, owner-only GET and PUT, 422 for unsupported or
unreadable files, video and audio made with ffmpeg lavfi sources and checked
with ffprobe; every remote media address goes through the proxy; the proxy
refuses unsigned URLs, streams ranges as 206 without caching, caches whole
downloads and serves them with ranges, and streams anything over
Media:MaxProxiedBytes (a SmallProxyHost) without caching.
- Provenance of local, delivered (signature) and fetched (instance actor,
no signature, the trigger as activity) posts, visibility of provenance,
instance descriptions; reading any of them makes no outbound request.
Pleroma reactions with EmojiReact and Undo deliveries, and local reaction
notifications.
Bugs fixed:
- remove_from_followers deleted the Follower row but never told a remote
follower. It now sends Reject{Follow} with the stored Follow id, through
RelationshipService.RemoveFollower, which Block now shares.
- VisibilityPolicy.CanSee refused followers-only posts to accepted followers,
so a post in their home timeline answered 404 to GET, context, favourite and
reply. Followers of the author (local or remote) may now see them.
- Account statuses of a remote account hid followers-only posts from
personas that follow it.
- exclude_replies dropped the author's own threads; like Mastodon it now
drops only replies to other accounts.
- A community account's statuses were always empty: they are now the posts
addressed to the community.
- Pinning someone else's visible post answered 404; it answers 422 like
Mastodon.
- GET /api/v1/notifications/:id answered 200 with null when the notification's
post was gone; it answers 404.

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.

Tests through the real routes of PeasantsController, WellKnownController and
UsersController, on the whole server under test (34 new tests):
- FederationGetTests: the actor document (activity+json, SPKI key at
#main-key owned by the actor, sharedInbox, published = PublishedOn's day,
no creation date, no root); ld+json; browsers sent to /@name; Vary: Accept;
/users 301; the outbox's totalItems and ?page=true&max_id paging across
the 20-item boundary, boosts as Announces, and no followers-only, direct,
located, federated-copy or deleted post; /groupies and /stalking naming
nobody; /trophies (public pins, newest first) and /tattoos; /scribbles
(public and unlisted 200, browsers redirected, followers-only, direct and
located 404, deleted 410 Tombstone); a circle post only for a signed member
or its instance actor; a circle's /groupies, /flock and /wardens only for
members; /grunts create- and announce- ids; /parrot-licences 200, revoked
410, wrong author 404; secure mode's 401 for every unsigned GET but the
instance actor's.
- WellKnownTests: WebFinger by acct:, @-prefixed, bare, upper-case and actor
URI; other domains, unknown names, a root's login name and no resource;
the instance actor, a community, a circle (answered: current behaviour);
NodeInfo links, 2.0 and 2.1 naming no root, unknown versions 404; usage
counting only public, unlisted, non-boost local posts (Exclusive).
- InboxRouteTests: all three inboxes accept a signed delivery and refuse
junk (400), unsigned (401), a bad Digest, a two-hour-old Date, a signature
for another host and a swapped body (401); an unknown persona's /mouth is
404; ld+json with the ActivityStreams profile is accepted; a signer whose
actor answers 503 gets 503 with Retry-After; the 301st unsigned POST from
one address is 429 while a signed server from it is not.
- PersonaSeparationHttpTests: with a sibling persona and its community on
the same login, every GET under /api (filled with the persona's ids) plus
search, lookup and relationships, and a crawl of everything federation
publishes about the persona (actor, outbox pages, collections, scribbles,
grunts, WebFinger, NodeInfo, /@ pages), never name the sibling, its
community or the login.
Fixed:
- A circle's /groupies told anyone how many followers (members) it has,
while its /flock and /wardens were already for members only; it now
answers 404 to anyone but a signed member or a member's instance actor.
- WebFinger answered 404 to a bare user@domain or @user@domain resource,
which Mastodon, GoToSocial and Pleroma all accept; it now treats them as
acct: (noted in docs/INTEROP.md).

96 integration tests through PrivaPubHost, the real pipeline end to end:
- OAuth: the token's subject is the persona, and neither the token response,
verify_credentials nor the stored token entries name the root. A wrong password shows
an error and sets no login cookie; a login without the antiforgery token is a 400; the
return address never leaves the site; deny answers access_denied with no code; another
root's persona re-renders the choice with no code; a banned root is sent back to the
login and a code issued before the ban buys no token; force_login asks again; a code
works once and its reuse revokes the token it bought; password and refresh_token
grants are refused; a client_credentials token gets 401 on user routes; a read-only
token gets 403 with a Mastodon error on POST /api/v1/statuses; follow covers
read:follows; revoke works; the login and authorize pages send their CSP and no-store;
the 11th /oauth/login from one address in a minute is a 429.
- Accounts: sign-up, duplicates in any case, invalid models answer 400 with a message,
login and logout, recovery email, settings, password change, invitation sign-up and
login (refusing a persona named after the login), recovery without an email, through
an unreachable mail server, with a wrong and with a valid code, token refresh, the 11th
sign-up from one address, expired, garbage and foreign-key JWTs.
- Personas: a rootId in the body is ignored, the username regex and reserved names hold,
personas and groups share ReservedName, an update delivers Update{Person} to followers,
PublishedOn and the id's day fall within two weeks before creation, the list holds only
one's own personas, another root's persona cannot be updated.
- Groups: communities and circles are created, joining takes the code and the password,
members leave and owners cannot, a remote follow request becomes a member only on
approval, a circle never shows in lookup, account by id, v2 search or /@name, and its
/flock and /wardens answer 404 unsigned and to non-members, 200 to a member's signed GET.
- Moderation (Exclusive, it suspends localhost): ban, unban and remove; non-admins get
403; reports are listed without the reporter and resolved; domain blocks are inserted,
listed and deleted, bad domains refused, and a suspended server's delivery is answered
202 and kept nowhere; the data endpoints.
- AdminCommands: exit codes 0, 1 and 2 and the resulting policies.
Fixed:
- A banned or removed root kept using /clientapi with its JWT until it expired: only /api
re-checked the root. JwtEvents.TokenValidated now loads the root and fails the request
when it is banned or deleted, and takes the policy claims from the database, so a
demoted admin loses admin at once (and a promoted one gains it).
- The 401 and 403 bodies JwtEvents writes were PascalCase while every other /clientapi
answer is camelCase; they now use the web defaults.
- /clientapi/user/sniff/again (token refresh) answered an empty 200; it now answers a
fresh JwtUser, like login.
- Password recovery answered SMTP reply codes as HTTP statuses (421, 454, 554, and 550 for
an invalid address); a mail server failure is now 503 and an invalid address 400.

Under /clientapi/admin/statistics, admin only (the root JWT's IsAdmin policy, like the domain
blocks; /api tokens are persona tokens):
- GET overview?days: totals per channel, inbound and outbound outcomes, the delivery
success rate, delivery latency p50/p95 from the buckets, active and known servers,
distinct accounts, and the ledger's written/dropped/failed counts;
- GET hosts?days&sort=volume|failures|latency|host&software&page&limit: per server
traffic, refusals, failures, latency, accounts, software and delivery health;
- GET hosts/{host}?days: the server's description, its daily series and its last 100
events;
- GET events?host&channel&outcome&reason&before&limit, and GET server?days for the
ServerDay rows;
- POST rollups/{day} refolds a past day; POST hosts/{host}/describe describes a server
again.
Days not yet rolled up, today included, are folded live from the events, so the numbers are
current. Answers that may carry locations carry the DB-IP attribution.

- IConnectedAddresses remembers which address each host's last connection reached, set in
SafeHttpHandlerFactory's connect callback. That is once per pooled connection, with no
second DNS lookup, and the address is never stored.
- IGeoLocator / DbIpLocator reads the offline DB-IP Lite city and ASN databases (MaxMind
.mmdb, via MaxMind.Db). It maps memory, swaps to new files within ten minutes, rounds
coordinates to one decimal, never looks up a private address, and answers nothing
when the files are missing. CdnNetworks names the CDNs whose edge addresses say nothing
about where a server is.
- deploy/max/geo-update.sh fetches this or last month's databases, checks them and swaps
them in atomically. The privapub-geo timer runs it monthly as www-data, and setup.sh
installs the directory, the script, the units and a first download.
Describing servers will use these in M8.

A RollupDay job folds each finished day's InteractionEvents into one InstanceDay per server:
- Counters for the admin, keyed channel:activity:object:outcome:reason, plus signature
schemes, audiences, local kinds and features;
- PublicCounters, everything a public page may ever read:
- inbound and outbound activities from an allowlist, on public, unlisted or unaddressed
traffic only, with the outcome collapsed (accepted or dropped, delivered or failed);
- no reasons, no Flag or Block;
- features of public objects;
- health:ok or health:failed from reachability (a 4xx means the server answered);
- latency, wait and byte histograms, and the number of distinct accounts from that day's
hashes.
Re-running a day replaces it and keeps the live Reads counters. The day's salt is then
deleted, so its hashes can never be recomputed, and the next day is queued.
StatisticsSchedule plans today's rollup every hour and catches up any of the last seven
days that have events but no rollup. Waits round up into their bucket.

- 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.

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.

NeverFiveHundredTests walks every endpoint the server maps and fills each route parameter
with junk ('x', zeroed and random ObjectIds, a dot-dot segment, 5000 characters). It calls
each one anonymously, as a persona, and with a junk token, and asserts that nothing
answers 5xx or throws, and that every /api error carries a Mastodon error body.
It found two bugs:
- A junk 'Authorization: Bearer' on any non-/api route, anonymous ones included
(/build.json, /peasants/*, inboxes), broke the response. JwtEvents.AuthenticationFailed
wrote a body during authentication and the endpoint then wrote its own. The 401 body now
comes from the Challenge event, which runs only when an endpoint needs a user.
- /api answered 401, 404 and 429 with no body. UseMastodonErrorBodies gives any /api error
that leaves without a body Mastodon's {"error": ...}.

PrivaPubHost is a WebApplicationFactory<Program> on the fixture's database, configured only
through UseSetting (visible before Build, unlike ConfigureAppConfiguration). It drops the
background workers so tests run the jobs they queue (Jobs.Run, RunInbox), gives each client
its own address for the rate limiter, and has a SecureMode variant. Accounts signs up roots,
adds personas and gets Mastodon tokens through the real /oauth code flow. RemoteActor signs
HttpRequestMessages for the real /peasants routes; Peer records bodies and headers and
serves files with ranges and text pages.
Program registers the Guid serializer with TryRegisterSerializer, so a second host in one
process starts; the fixture runs the migrations in production's order before any test.
HostBootTests: the host shares the fixture database; the harness handles exactly the
activities the server registers; every job kind has one handler; every controller and page
model can be made; the service graph validates with ValidateOnBuild and ValidateScopes;
Swagger is 404 outside Development; a persona's token never names its root; a signed DM
through the real /mouth route is queued, processed and stored.

- JobQueue takes an optional scope, so a test's worker leases and reaps only its own jobs.
- The dead-host delivery test runs alone (Exclusive), on its own jobs, and cleans up the
breaker rows it trips; the breaker has tests of its own on unique hosts.
- Index and migration tests run alone: they drop indexes and rewrite every post.
- DomainBlocks.Load replaces reflection and a database-wide block in tests.
- Harness.Outgoing sees only deliveries queued since the harness started: Peer ports are
reused within a run, which made the circle test flaky.
- Two pure-logic tests leave Mongo-gated classes, so CI runs them.

- 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.

- The media proxy streams ranged requests from the origin (passing the range on, never caching), downloads and caches
whole files otherwise, and serves cached files with range support. A PeerTube video is never fetched whole for one
viewer, and clients still never contact the remote host.
- PeerTube's fragmented MP4 files inside an HLS entry are read as variants, so HLS-only instances play too.
- A remote Video or Audio post becomes one playable Mastodon attachment: the best MP4 up to 720p that carries both
sound and picture, with its poster and duration; the card is kept only when nothing is playable.
- nginx: /media/proxy/ with proxy_buffering off and a 600 s read timeout (applied on the box, with a backup).
Checked live: a GoToSocial image through the proxy answers 206 with exactly the asked range when streamed, 200 when
cached, and 206 with the right Content-Range from the cache.

- 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.

- 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.

- 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.

- 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.

- ObjectShapes reads `url`, `icon` and `image` as a value, a Link or an array; Markdown `content` (PeerTube) is
rendered; a missing `mediaType` is inferred from the extension or the attachment type (Bridgy); alt text comes from
`name`, `summary` or their language maps; thumbnails come from attachment `icon`, object `icon[]`, `image` or a Loops
`preview`; durations are ISO 8601 or seconds; per-attachment `sensitive` is kept; the language falls back to
`@context` `@language` (Pleroma); titles and excerpts are plain text; hashtags normalise with NFKC like Mastodon.
- Typed details on Post: Link (Lemmy link posts, Mbin `source` URLs, Mastodon 4.7 Link attachments with an FEP-8967
publisher preview), Video (PeerTube files with their streams, HLS playlist, poster, captions, chapters, licence,
channel, live state, comment policy), Audio (Funkwhale), Event (Mobilizon, Gancio, Hubzilla: times, zone, floating
time, places and addresses, online link, capacity, status), the cover image, and the author's own source text.
- Mastodon API: a card built from those details without fetching anything, an event's "when · where" line, attachment
thumbnails and durations, and no media file offered as a preview image.

- 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 remote `summary` is a content warning only on a Note or Question, or when `sensitive` is set. On Articles,
Events, Videos, Pages and Audio it is an excerpt (WordPress teasers, Mobilizon dates and places, Mbin titles) and
is now kept as `Post.Excerpt` instead of hiding the post. `Post.ObjectType` records the remote type, and the
Mastodon API shows a remote non-Note object's title above its body again.
- Persona usernames must match `^[a-z0-9_]+$`, as groups already did; a name outside it was unreachable from
Mastodon and Misskey.
- `postingRestrictedToMods` is defined in our JSON-LD context (Iceshrimp.NET drops undefined terms).
- `Vary: Accept` on actor and object URLs.
- Owner decision: blocks federate. A block sends `Block`, an unblock `Undo{Block}`; checked live against GoToSocial.
- Owner decision: a persona's and a group's `published`, and the day in new ids, is a random day up to two weeks
before creation, so personas made the same day no longer share a date. Migration _007 gives existing ones theirs.

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.

Found by the first live run against GoToSocial:
- A remote post's id came from its published second plus random bytes, so a reply arriving in the same second as
the post it answers could sort under it, and a late arrival landed behind a client's since_id. A post published
within the last hour now gets an id for its arrival; backfill keeps its published time.
- NoteParser.Time returned default(DateTime) for a missing "updated", so every remote post was stored as edited in
year one. Migration _006 clears the stored ones.
- published now carries milliseconds, so peers that derive ids from it (GoToSocial, Mastodon) keep our posts in
order within a second.

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.

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.

- /api/v1/media and /api/v2/media (and GET/PUT /api/v1/media/:id):
images go through libvips (NetVips, its native build bundled):
autorotated, every kind of metadata dropped (EXIF, GPS, XMP, IPTC,
comments), capped at 4096 px, with a 640 px preview and a blurhash
(own encoder, the reference algorithm); animated GIFs are re-encoded;
video and audio are remuxed by ffmpeg with -map_metadata -1, never
re-encoded, and a video gets a still preview. Files get random names
under /var/lib/privapub/media, outside the web root deploys replace, and
are served at /media/files with nosniff and a sandbox CSP.
- media_ids on create and edit (four at most, the persona's own, each used
once); notes carry them as Document attachments with alt text, blurhash,
focalPoint and size; inbound attachments were already kept.
- avatar and header uploads in update_credentials, cropped to 400x400 and
1500x500, federated with Update{Person}.
- Remote media reaches clients only through /media/proxy/{hmac}/{url},
fetched by the guarded client (no SVG, 40 MB cap) and cached outside the
served root, trimmed to 5 GB; foreign avatars and headers use it too, so
a client never contacts another server.
- MediaJanitor deletes uploads left unattached for a day.
- nginx accepts 100 MB bodies on the upload endpoints only (applied on Max).

- 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.

- PersonaSeparationTests: two personas of one login follow the same
account and post; nothing the API maps for one contains the other's id,
username or the root id.
- tools/smoke/mastodon-api.sh checks what a client meets first (instance
v1/v2, discovery, app registration, client credentials, an app token
refused by a user endpoint, the public timeline, revocation) and, given
a persona token, verify_credentials, home and notifications. deploy.yml
runs it after every deploy.
- OAuthPruner removes invalid tokens and authorizations older than two
weeks, every six hours.
- The consent page no longer sets form-action, which browsers apply to the
redirect back to the client after the form is posted.

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.

Domain/Statuses/StatusService takes a persona, not a root, and is what
/clientapi and the Mastodon API share:
- Publish renders Markdown (clientapi) or plain text (Mastodon clients),
checks the persona may see the post it replies to, opens or reuses the
conversation for a direct post from its recipients and mentions, fans
out and hands the Create to the outbox;
- Edit keeps a revision and sends Update{Note}; Remove soft-deletes and
returns the post, so a client can delete and redraft;
- Favourite and Reblog work on anything the persona can see and send Like,
Announce and their Undo to the author (and, for boosts, to followers);
boosts are refused for anything but public and unlisted posts.
PostsService is now the clientapi wrapper that checks the root owns the
persona. A persona's own boost is a local row: the outbox renders it as
Announce, /grunts/announce-{id} resolves, and object endpoints, profile
pages and NodeInfo skip it. ContentFormat gains Plain.

OpenIddict 7.7 (MongoDB stores, keys kept in Mongo so tokens survive
restarts) serves /oauth/authorize, /oauth/token, /oauth/revoke and the
discovery documents, including /.well-known/oauth-authorization-server:
- authorization code (PKCE optional) and client credentials, Mastodon's
scopes including the granular ones, non-expiring reference tokens,
`created_at` in the token response, and the urn:ietf:wg:oauth:2.0:oob
page that shows the code;
- /oauth/login signs the private login into a fifteen-minute cookie that
only /oauth sees (rate limited, antiforgery-protected); /oauth/authorize
then asks which persona the application acts as. The token's subject
is that persona's id and nothing else; no root id reaches a token, an
authorization or a log line;
- the token exchange refuses a persona whose login is banned or deleted,
and every API request checks the same.
/api/v1/apps registers applications dynamically, /api/v1/apps/
verify_credentials, /api/v1/instance (v1 and v2, "4.2.0 (compatible;
PrivaPub)") and verify_credentials answer in Mastodon's shapes: snake_case
with explicit nulls, Rails-style parameters from query, form or JSON,
{"error": ...} on failure, Link paging. CORS exposes Link.
/api goes to OpenIddict validation and everything else to the existing
JWT; the JWT failure handler no longer sends the exception and stack trace
to the client.

Deleting a remote post now removes its timeline entries and the reblogs

- Like: a Favourite per account and post (unique), the post's counter, a
Favourite notification for a local author; only on posts the liker
could see (public and unlisted, or followers-only and direct when they
were addressed).
- Announce: the original is always refetched from its own origin (or is
ours), and must be public or unlisted. A boost of a local post counts
and notifies; a boost by an account a persona follows is stored as a
reblog row and fanned out to its followers' home timelines (as a reblog,
where reblogs are wanted). A boost by a stranger of a stranger's post is
ignored. FEP-1b12 group announces of activities wait for P4.
- Undo of a Like or an Announce reverses each of them; an Undo naming only
an id is matched against follows, likes and boosts in turn.

Fanout writes a TimelineEntry for every persona a post should reach: the
author, local followers of a local author, local followers of a remote one,
the members of a direct conversation or a circle. Mastodon's home rules
apply when it is written: a reply shows only to followers of both sides
(or to the one replied to), a reblog only where reblogs are wanted. A
mention of a local persona becomes a Mention notification.
Inbound posts are now also kept when a persona follows their author.
RemotePosts holds what CreateHandler and backfill share: building a Post
from a note, and fetching a public parent the first time a reply to it
arrives, so its author is known (a reply to an unknown or non-public
parent stays out of home timelines). Each fetched ancestor queues a
FetchAncestors job for the next one, up to ten deep.
/clientapi/timeline/home and /clientapi/notifications (with
/notifications/read) page by max_id for the persona's own root only.

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.

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.

VisibilityPolicy.IsPublic is the single expression for "anyone may see
this" (Public or Unlisted, not deleted); the outbox, the object and
activity endpoints, the HTML pages and NodeInfo all use it instead of
spelling it out. CanSee answers for a persona: the author, a mentioned
local persona, a conversation member for Direct, a circle member for
Circle; followers-only waits for P1.2's follows.

An ObjectId carries its creation second and a per-process counter, so two
avatars made one after the other by the same login got ids a few counts
apart: a link between personas that every Mastodon client would have
seen. Avatar and Group now generate ids from the UTC day plus eight random
bytes (still valid ObjectIds), and a remote post's id is made from its
published time with a random tail, so posts page in the order they were
written rather than the order they arrived.
