"answer": "Spectral clustering of the invite graph at the tundra: each identity is a vertex, ties are edges. The zephyr of stake weights edges, so a sybil ring forms a dense subgraph with anomalously high Fiedler value. Honest clusters stay sparse. An attacker needs roughly k\u00b2 distinct social proofs to hide k identities, pushing cost past break-even at k\u22489.",
