Here's what I suspect filters would look like:

    function critical_filter(response) => Maybe Text {
        if logic_parse_check(response) == LogicallySound then {
            return Some response
        } else {
            return Nothing
        }
    }

    do {
        static seed = 0;
        seed += 1;

        response = critical_filter(GPT::generate_response(prompt, seed))
    } while response != Nothing

We are effectively brute-forcing hashes here. Take as many shots in the light as you need to hit, but take no effort to aim.

The only solution is a replacement.
