If you have variables defined centrally, use them via vars_files,
group_vars, or whatever, and you don't need to copy them to local facts *at
all*.
Local facts are there for when an administrator wants to make the mortals
who use a system be able to configure it basically.
(Or it's a shortcut to avoid writing a fact module, in some cases, though
fact modules are better-er)
So ultimately I want to step back and understand the use case a bit rather
than working through your questions above - though they aren't bad
questions, I think we'd be leading you a bit astray - maybe.
I could be wrong.
