# Activity-Relay 2.0.9 (yukimochi): a Mastodon-style relay as relay.test. A server subscribes by following Public from an
# actor with a shared inbox; the relay then passes on, signed with its own key, every public activity another subscriber
# sends it (a LitePub-style follower, whose actor ends in /relay, gets an Announce instead). Its state is in the shared
# Redis (database 13); its actor key is made once. Go trusts the bundle the pasture mounts over the system one.
