Where the assets you own or license actually live, and how Stacks help organize them.
My Network is where every asset you own outright ends up after a completed Exclusive purchase — it's your inventory of owned Nodes, plus any assets you've added that didn't come from a TrafficNodes purchase.
My Licenses is the parallel view for Replicable and Subscription purchases — assets you have an entitlement to use, not ownership of. The two are kept visually and structurally separate so it's never ambiguous which one applies.
A Stack is a way to group related assets from My Network together — for example, everything supporting one campaign or one offer. Stacks are organizational only; they don't change ownership or create any commercial relationship between the grouped assets.
