But, I'll check it - and report back - with pictures.
We'd expect nothing less from the professional you are.

I gathered the testing equipment:

I turned off the wall switch (it's turned on in this pic):

I removed the cover of the inlex box from the BX cable:

I separated the hot (black), neutral (white) & ground (green):

Turning power on, I tested neutral to ground at 0 volts AC:

Turning power on, I tested hot to ground at nominally 120VAC.

I turned the power off, and reconnected the wires as before.

If the power is reversed, it's not at the inlet BX cable
connection to the unit.

What I mostly want to find is the big red button that says
"reset", but I don't see it. I see a bunch of smaller limit
resets, all of which I've pressed already.
