I did find this software https://github.com/FreeAndFair/OpenCount https://github.com/FreeAndFair/OpenCount That was funded by UC Berkley and has a tabulator part that appears to work on the common voting systems. Readme states "Tabulator currently supports optical-scan ballots associated with Diebold (Premier), ES&S, Hart, and Sequoia ballot styles" Since Dominion acquired Sequoia in 2014, I am guessing some small changes would make this work for the current ballot images used in 2020.
