Kammback drawback: extra-filthy rear end!
I have never had the back of a be-Kammbacked car get as dirty as this Mirage does. This is accumulation from normal winter highway driving - not driving on any dirt or gravel roads.
Then again, I have never put side skirts on a car before this one either. Maybe they changed flow/pressure enough at the rear to make this mess.
I usually delete the rear wiper/motor assembly on my cars. I can't do it on the Mirage or I won't be able to see out the rear within a short amount of time on a wet winter highway.

I wonder if adding a small extension straight back on the bumper would help? I can see a vertical line of dirt formed on the left side of your bumper. Wonder if that would change flow just enough to let the dirt be flung to the ground instead of back at your car?

I noticed that vertical line too, but I think it's just where the rain & snow has washed the dirt off - not protected from above by the Kammback.
(I haven't washed the car yet since I got it. )

That said... I'm thinking of testing a quick 'n' dirty box cavity. I wonder if that will keep it cleaner.

Part of it is there is an awning now preventing rain and snowfall from washing the back while it's parked.
Oh I just saw where you already said that.

Also: the Metro & Firefly had similar setups, and they didn't get nearly that filthy! I could run them without a rear wiper/washer.

Yep. Here's the same thing on a Saab 95. First pic shows the extended lip at the trailing edge of the roof, second pic shows the slot for directing a wash of air over the back window to keep it clean(ish). This is what happens when you let airplane folks design a car.

back-soiling
I wonder if placing a 'floor' in the K extension,would sequester the water-borne debris away from the glass.The high-inertia water might not be able to make the corner,and you'd
have a pond of dead air inside the extension,at high static pressure,like a box-cavity.
