I can write more later, but here’s a relevant doc I wrote as part of discussion with Geoffrey + others. Maybe the key point from there is that I don’t think this protocol solves the examples given in the original post describing obfuscated arguments. But yeah, I was always thinking this was a completeness problem (the original post poses the problem as distinguishing a certain class of honest arguments from dishonest obfuscated arguments—not claiming you can’t get soundness by just ignoring any arguments that are plausibly obfuscated.)
