Request for clarity on background processes for CC/OC agent integration

I've been trying react grab and while I think the core feature of driving an agent via the react grab selector is great, I've noticed background processes not getting cleaned up when I kill the server. This might just be a issue solely on my side, but I find myself a bit confused on the expected state of background processes.

Could someone provide a quick mermaid diagram or something that shows the relationship/lifecycle of the processes active processes when using the agent integration? It would help me a lot in debugging.
