Not sure I understand it either. 🤣
I understand the end result: a mixing engineer getting all the tracks separately to do the work.
A tree, at the core the combined work, evolving at each step, the bounces for reference.
At each step, branches with the various versions of the layer being added to the song (drums, base, vocals, harp, and so on). There will be back and forth until agreement and validation. (Can you try this? Can you try that? Creative soup)
Ideally, once the creative stuff is done, you should be able to pull all stems that have been validated with one click (and any XML or similar that could be shared in the process) to send it to mix and master.
For the beat in question here, yes, I’d need to get the separate tracks from you and #[4]​ to build a structure once I understand what #[3]​ is cooking
