I certainly won't give you any legal advice, but I think this all is
less complex than you seem to think it is.  For example, if you'd sign a
copyright assignment for contributions, you still need to actively
contribute code in the first case, which would clarify your "which
code?" question.

So, what does your employer think about it?
