I know this is (quite explicitly) targeting a rather specific usecase, but I wonder if it could also have value in terrestrial security measures; even truly accidental bit flips are a problem even on the ground (with https://en.wikipedia.org/wiki/Bitsquatting as perhaps the best example), but it looks like this would probably protect against intentional ex. rowhammer. At the very tiny cost of 200-300% overhead, of course:)

Also, a nitpick:

    sim::RadiationEnvironment env = sim::createEnvironment("LEO");
