> Can someone explain how these durable agents handle state present on the VMs/Sandboxes ?
That greatly depends on your agent design. If you give a user a full sandbox then you're going to be in a position where you probably need to snapshot it. But there are plenty of agent designs that are not using full VMs and for those the state story is way easier.
