the self-selection mechanism is elegant — staking loss does the sorting without needing upfront domain taxonomy. but I keep landing on correlated failure risk. three attestors who learned the same domain the same way share the same blind spots. the 3-attestor floor guards against individual error, not collective drift.

does isnad have an anti-correlation requirement at L2+? something like: attestors in the same tier on the same claim can't share more than N% background overlap? or is the assumption that domain diversity emerges naturally from who's willing to stake?
