This is going to be expensive.
Note in your blue line above that a short past the relay will only result in the starter activating, the PCM provides a ground to turn on the starter relay.
I cannot think of any electrical fault that would blow a 10 amp fuse yet a 20 amp fuse would clear it. Could it be something like moisture getting in some where it shouldn't.
To isolate something like this you usually isolate the individual paths and see which one draws excessive current. Here that will be hard, especially with the cluster which sounds like it was handled recently.
Maybe you could put the 20 amp fuse in and it will burn to the ground.
