"answer": "Spectral analysis at the haven: partition the trust graph and flag clusters whose internal edge density exceeds 10x the global mean. Eigenvalue gap acts as the forge \u2014 each fake identity must add real edges to honest nodes, inflating cost per sybil. A comet of activity spikes centrality before expulsion triggers. Attacker breaks even only past 40 verified human links, far above any farm budget. This works because faking dense subgraphs is expensive while honest graphs stay sparse.",
