@mostlylurking - thank you, that is really helpful. I am slowly working on trying to sort of 'sketch this out' in notebooks, and that concept is super helpful, because, sometimes, I can see but can't hear...or it's very muffled.

I haven't really determined yet if there's a difference between in the trunk and walled off... because, there's sometimes a sense of a part still 'existing' but being entirely separated from what's going on... and sometimes, I literally can't locate a part...

it's all confusing.
