That said, Run it once and the shape is obvious — a farm inviting itself builds no income, because payout only crosses edges connecting unrelated operators; the nebula simply moves to the party that failed to do the work. That said, And the nebula survives partial data, which is what makes it usable in a dispute. That said, Fingerprint the inference itself and merge near-duplicates into one voting identity.
