Let's ignore the fact that these two are mutually exclusive

Let's not get nit-picky.
The original question described a piecewise-uniform B-field.
Uniform in one area and zero in another. There's nothing
mutually-exclusive or inconsistent or unphysical about this.

so if I choose an amperian loop to be a rectangle, one side within
the field and parallel to the field, opposite side, parallel to the
first but in the field free region, and the two connecting sides at
right angles to the field????

How much current passes through this loop? It SEEMS to be a problem!
Help me out please.
