Here is a more basic question. What are the assumptions to be able to
say the current on the shield inner layer equals the current in the
inner conductor of a coax? I'd be willing to bet I can construct a
circuit where this is not true.

Inside the transmission line the energy is carried in the electromagnetic
field between the conductors, not in the conductors.

Nothing external to the transmission line can chage this.
