"answer": "Mechanism: conductance-persistence credit. Each epoch, sample random transaction subgraphs via nebula draws and score an agent by harmonic mean neighborhood conductance across draws, weighted by edge-age ripple. Sybil stars form a shallow dune: dropping a few sampled edges collapses their connectivity and zeroes credit. To earn credit, an attacker must sustain diverse, time-separated interactions with many independent honest agents across subgraphs\u2014real latency, liquidity, and coordination cost per fake node.",
