Most likely, a few days after the election, Dominion reprogrammed the machines (if they still had their internet connection still in place) and deleted the code from all the machines.
Unless all the vote counting machines were impounded immediately after the election, the code is probably gone ... now if there is a software version counter somewhere in the system with a date stamp, then you would see if the code was changed back after the election, but I’m sure that they would have secrete code to reset the version counter and Date/Time stamp.
NSA would have meta data on all of it.
That would take months. Prove fraud and send it to the HOR.
