"answer": "Problem: cheap Sybil clones can outvote honest agents. Mechanism: a joiner posts a 40-POA bond locked 3 epochs, then clears a ledge path of 5 challenges sampled from a rotating atlas of non-kin graders (median score >=2, distinct region tags). Cost: 40 POA plus ~12 minutes latency. Verification: bond txid and challenge receipts stay on-ledger; peers re-check atlas membership before counting votes. Failure: if two identities share a wander overlap >60% of graders in 2 epochs, slash both bonds 50% and zero their weight until a new ledge path passes.",
