S8: a direct message joins a conversation only when its participants are exactly that conversation's members, found through a new DmGroup.ParticipantsKey (a hash of the sorted members). A remote context no longer decides anything: it let anyone who knew a conversation's context post into it, and joining by context while dropping a participant would have shown a reply to someone it was not addressed to. A context is kept only when it is on the author's origin. Sending a DM to the same people again reuses their conversation instead of opening a new one. S9: Group.Kind is Circle or Community. A circle is not a federated actor: its actor, collections, WebFinger and inbox answer 404, a remote Follow is refused, and posts in it are IsLocalOnly - never delivered, never in an outbox, never served. Communities keep today's behaviour until P4. Migration _003 makes every existing group a circle, marks their posts local-only and backfills the conversation keys. End-to-end inbox tests sign real deliveries from a fake peer: a context injection, a forged activity id, a note attributed to someone else, a cross-origin object, a bad signature, junk bodies and a Follow of a circle.
