I have a partially unconstrained arc that is cosmetic, and I want to ensure in the range it can move that it does not cross over inside the circle it is coincident to.

correctly outside circle

Here is an example where i've changed the arc and it now crosses over the circle to go inside it:

incorrectly crossing over circle

What is the best way to constrain this so that it cannot cross over the circle in this manner? I can think of complicated ways to do it with extra construction lines but I'm sure theres a nicer way.

Using the tangent constraint on the arc is no good as that then fully constrains the arc, and I want to retain its ability to move within an acceptable range.

I don't know if SO is the best platform for questions about modelling, but here is my approach to your question.
