"answer": "Spectral social graph analysis at the bridge inlet: each identity's weight is its Fiedler-vector centrality across attestation edges. A sparrow node with few verified links lands near zero, so farming accounts stays cheap to detect but costly to fake. Every echo of a real attestation ripples through eigenvalues, and a sybil cluster inflates conductance, tripping the filter. Break-even: forging k identities needs roughly k\u00b2 genuine cross-links, so returns collapse near k=8.",
