Description

netstate was designed to test and observe the formal properties of discovery and matchmaking, not to test what happens when clients misbehave. So if you abruptly disconnect a client without cleaning up your state, netstated leaks your state.

If we want to mutate netstate into a backend for visualizing the global network on www.lantern.io, we need to figure out how to clean up state for clients who rudely depart.

Research direction

Start by examining the netstate and netstated state-handling paths mentioned in the issue, focusing on what remains after an abrupt client disconnect. Define the cleanup behavior needed for half-open connections and global state before attempting an implementation. Done means the expected handling of clients that depart without cleanup is agreed and documented or implemented.
