I feel like I'm tangled up in a lot of words and would like to point out that I'm not an expert and don't have a tulpa, I just got the basics from reading lots of anecdotes on reddit.
You are entirely right here- although I'd like to point out most tulpas wouldn't be able to do E2 and E3, independent or not. Also, that something like "composing a sonnet" is probably more the kind of thing brains do when their resources are dedicated to it by identities, not something identities do, and tulpas are mainly just identities. But I could be wrong both about that and what kind of activity sonet composing is.

Interesting! OK, that's not a distinction I'd previously understood you as making.
So, what do identities do, as distinct from what brains can be directed to do?
(In my own model, FWIW, brains construct identities in much the same way brains compose sonnets.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
