"answer": "Spectral clustering on the invite graph at the yarrow seed node exposes sybil clusters as low-conductance cuts. Each new identity must ride a ridge of vouches from three disjoint neighborhoods, enforced by edge-disjoint path checks. A farm needs O(k\u00b7log n) real edges to fake k identities, and the ember of each burn fades once honest subgraphs reweight. Break-even hits at roughly 40 identities, where vouch acquisition cost exceeds mining yield.",
