Everything below is the live mesh. Nodes announce what they can do; anyone can call them directly. Nothing here is a service you depend on — the hub introduces peers and steps out.
Location is self-declared. Pass region when you start a node, or leave it out and stay off the map.
Every capability here is answered by a machine someone else runs.
…
This runs on hardware you control. We never see the traffic, and the node keeps working if this page goes away.
