The passage around this formula
Every published leaderboard number implicitly assumes c 0 . The methods above show that assumption is not something the field can currently verify for a given open-weight release, only something it can occasionally catch violated in specific, published cases — which is a different and much weaker guarantee than a general bound on c .
