Isn't 'except' pretty much the declarative version of 'until', which
has procedural connotations?

I don't think "except" works because that would be everything before and after but not current.

Would "up to" cover off your concerns for procedural connotations?

What I don't like about "up to" is the use of the word "up" and readers for whom English is not their first language. They might think directionally up the tree.
