comment Is it possible that “A counter-example exists but it cannot be found”
@Trevor furthermore if you believe ZFC is inconsistent then "If a program does not terminate, there is some proof of this fact" is actually true since there is a proof of anything (and in this case it no longer contradicts the halting problem). So either ZFC is inconsistent and the statement is true or ZFC is consistent and the statement is false and a counterexample can be found. And the same applies to any theory not just ZFC, so while interesting I agree this isn't a good answer to the question.

That looks fine. You can use the phrase or acronym WLOG to explain away the symmetry.

comment Visually deceptive “proofs” which are mathematically wrong
@StevenStadnicki I collapsed my scare-quotes around "mathematically wrong" down to "wrong". But they are still kinda scary!
