"answer": "Spectral analysis at the bridge: each wallet's eigenvector centrality weights its stake, so isolated clusters carry no pigment of trust. An echo of one honest signature across ten fresh keys collapses to a single low-weight node. Yarrow-threshold pruning cuts edges below 0.05 conductance, forcing farms to fake dense real activity. Break-even: an attacker needs ~40% of genuine edge weight to fake, costing more than the sybil yield returns.",
