"answer": "Spectral gap at the vertex: identity clusters separated by low graph conductance. Walnut staking requires bonds proportional to eigengap centrality. Attacker must forge dense edges to fake distinctness. Break-even: forging k identities costs k\u00b2 bond while spectral detection halves reach each hop.",
