Re: dumb scanners?

Another issue would be overvote protection. The scanner would have to know something about the structure of the races to do that, not just xy positions. Likewise, reports of simple totals by XY posiiton would not suffice for Ranked Choice voting.

the equipment might also be like that used for SAT test card scoring.

I note that many older DRE machines, like the Danher/Shoutronics, actually are "dumb" in an analogus way. They don't actually know anything about who you voted for. It just knows that a certain button being pressed causes a specific memory location to be incremented. They actually "program" these things using graph paper to layout the assignements--there's no high-level markup language for "ballot description". The candidates names and parties only appear on the printed surface of machine and not in the memory. Raw output is just totals by memory location.

I would assume that the Opscans in use today are internally almost the same. Just incrmenting pre-assigned memory locations without knowledge of candidate names.

the trickiness in the opscans is the assinment of these by ballot style and the overvote protection, which requires some additional logic in the ballot definition.
