> 5. The adversary's guard can observe the hidden service's IP directly.
So does the guard know that it is a guard and that the traffic comes from a hidden service? I thought Tor worked by jumping from node to node, and that each node didn't know whether the traffic came from the original client/service or from another node in the chain. So each time you make a connection over Tor you're essentially telling a guard node "here's my real IP, send this traffic to this hidden service and return the response please" and you have to trust that they keep it a secret? I feel like I'm missing something here.
