Ideally, I'd like to use a saved geometric model (.gms) in Spatial Modeler but I think that's not possible. Therefore, I think the only way to do a polynomial correction is to use control points. Does anyone have a working model that does this. Or and example of the json format control point file needed as input?
At the point where you are creating and saving the geometric model can you simply geometrically calibrate the image the model is associated with? That way you don't need to bother about it - you would just use the image in Spatial Modeler and resample or not as needed?

True, but i (customer) has multiple datasets that will use the same model, and I want to put it into a flow line. There's stuff to do both before and after the rectification.
Mmmmmm ... not sure you can have a "generic" .gms model. Such models will almost always be specifc to an image. Unless all the input images have the same size (rows / columns) and (target) map extent? If that's the case then yes, you might be able to use a single .gms. But that seems like a very unlikely scenario - can you describe the circumstacnes where this si true for your data?
"There's stuff to do both before and after the rectification." - gemetrically calibrating the data prior to inputting it to Spatial Modeler should not prevent you from doing this. No warping would happen until you tell (or cause) it to happen in the Spatial Model.
