Oh, I see. Your pedalroom led me to believe otherwise.
Weird fit is weird.

Just out of curiosity, are you saying a 10 degree rise/drop is uncommon without a spacer?

Nope. It's just that you are looking for a chode stem with a lot of drop.
You probably want a 17 degree stem if you're looking for that "level aesthetic". A 10 degree stem in the "drop" position will still have some rise from flat.

The Thomson X2 comes in 70mm with a +/- 10° rise. Pretty sure that's as close as you're going to get. I honestly can't see why anyone would want to use such a short stem with more drop than that.

Is your frame just too big?

I didn't catch your edit. When the stem is installed on the bike there really won't be much of a drop, really just looking for a level or close to level position. X2 will probably fit the bill.

You're using your words wrong.
"Tight geometry" generally refers to seat tube and head tube angles greater than 73 degrees as well as shorter front end and chain stay measurements.
"Chode stems" generally refer to stems too short for effective rider placement. Generally used by riders with a less than ideal amount of knowledge about how a bike is supposed to fit. This creates issues with the handling and rider comfort during different positions. You want a frame with a proper length top-tube so you can use an appropriate length stem (80/90-120mm)
I don't think you know what you're doing with respect to fitting.

Just picked up a 90mm Thomson X4 by the way, appreciate the advice Scrod and Yummy.

Frame geometry is frame geometry, regardless of what length stem you have or how big your britches are.

When referring to the geometry of a bike, no - because those are all variables that can change. As myself and others have told you, "geometry" refers to angles/length of a frame's tubes. You can change the height/length of your stem until you pass out. You cannot change the length or angle of your head tube.

That's irrelevant though, geometry can change, no?

What is your culture where frame geometry includes things that are not frame?
Is there some secret culture in Boston I don't know about? I have ridden in Boston many times, most riders seemed about as knowledgable as any other city. There are lots of high quality bike builders in the Boston area. So I am sure they know what they are talking about.
Maybe your culture is just you, if so keep going with that. It will make advice much easier to get.
_________________________________________________________________________________
Read the things posted, you will learn things.
Geometry- The angles and measures of your frame. The length of the seat tube, top tube, headtube, and chain stays as well as the angles of the headtube and seattube.
Fit- The combo of the geometry of the frame, along with the placement of everything added to the bike. The height, angle, and location of the saddle. The height, angle and location of the bars. And the length of crank. If you are riding clipless sometimes the location of the cleats on your shoes is also included.
Geometry can never change on a frame, you can change all sorts of things about the fit.

I never mentioned frame geometry specifically, just geometry. Geometry is just the position of things and things in relation to each other. In your culture, the word geometry apparently only refers to the unchanging geometry of the frame, I wasn't aware of that. Not knocking your culture, relax.

Then you don't know what you're talking about.
