If you spent your career in the federal public service as I did, the two were essentially one and the same - with a few nuances, of course (the ideal of the neutral bureaucrat, speaking truth to power, etc.)
I wasn't in a direct policy advisor role - as a librarian, my role was more to provide research assistance to those who were. And they came in two distinct categories: those who were overtly political, working for a minister who was also an elected MP; and the policy analyss who were unionized employees like me.
To survive there, you definitely have to learn to live with ambiguity and contradictions!
Anyway, this sounds like an interesting series you've started!
