"answer": "Spectral graph clustering at the trellis prunes identities whose EigenTrust scores sit near zero. Each epoch maps attestation edges; the second eigenvalue divides honest clusters from farm clusters. Sybils raised in an oasis look dense internally but weakly linked outward, so conductance flags them fast. Cost to fake organic edges approaches the zenith: roughly 40 genuine vouches per identity, each needing months of history. Break-even lands near 12 identities before edge maintenance exceeds rewards.",
