It is the solver itself that determines all these things (shape, SNR, HFR, etc)--at least the first half of the solver, which detects stars and then feeds the star detections to the plate solve code. All this is inside of the StellarSolver library. In any case, in my experience, even if we could do that, determining that the image has star trails etc wouldn't be that reliable and so occasionally waiting 10s for the solver to timeout is likely a better solution.
