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.

tools/ci/with-test-mongod.sh starts mongod (or podman's mongo:8) on a random localhost port
with a temporary data directory, runs the command, and removes both. build.yml and deploy.yml
test through it, so the ~85 integration tests stop being skipped in CI. MongoFixture refuses
production's port and data directory, and in CI anything but the wrapper's mongod; with
PRIVAPUB_TEST_REQUIRE_MONGOD=1 a missing mongod fails instead of skipping.
The deploy now passes the PRIVAPUB_SMOKE_TOKEN secret to the Mastodon smoke check, so its
signed-in half runs once the owner creates the persona and the secret.

The single serial DeliveryWorker is replaced by Infrastructure/Jobs:
- Job rows are leased with one FindOneAndUpdate (oldest RunAt first, a
two-minute lease) and a reaper returns expired leases every 30 s;
- enqueueing wakes the workers, which otherwise poll every five seconds;
- delivery runs eight at a time with at most two per host, so a slow or
dead server holds two slots, not the queue;
- a failure waits n^4 + 15 + jitter seconds (Mastodon's curve) for up to
16 attempts; a 4xx other than 408/429 is final, a 429 honours
Retry-After;
- RemoteInstance is a per-host circuit breaker: ten consecutive failures
quarantine a host for an hour, doubling to a week, and its jobs wait
without spending attempts;
- a delivery is queued once per activity and inbox (unique DedupeKey), and
finished jobs expire after seven days (TTL on FinishedAt).
Migration _004 moves pending Delivery rows into jobs and marks them
abandoned, so a rollback to the old worker cannot send them twice.

Infrastructure/Data/Indexes runs at every start, after the migrations:
unique on Post/DmPost ObjectURI, ForeignAvatar ActorURI, the Follower
triple, RootToAvatar, RootUser UserName and ReservedName; plain indexes on
the lookups the services actually make (PublicKeyId, author and group
post listings, ParticipantsKey, the delivery queue).
Migration _001 runs first and removes the duplicates the races could
already have left (keeping the newest actor row, the oldest post, the
accepted follower), then fills ReservedName from every avatar and group.
ReservedName is one username space for personas, groups and the instance:
a name is reserved by an insert the unique index arbitrates, before the
avatar or group is saved, so two simultaneous sign-ups cannot both get it.
A short list of names (admin, support, abuse, postmaster, ...) is never
available.
EntityMaps.Warm touches every entity's collection one at a time before
anything else runs. MongoDB.Entities maps the Entity base class on first
touch, and two types mapped at once throw "An item with the same key has
already been added" and stay broken for the life of the process; the
parallel test run hit it, and the delivery worker racing a request could
have too.

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