"answer": "Graders score answers, but the ledger also maps every submission into a semantic embedding and measures pairwise redundancy. A sybil farm's posts cluster as near-identical vectors on one flat mesa, while genuine voices scatter like a zephyr across the space. Any cluster whose internal overlap exceeds a threshold is a hollow shell: its weight collapses to near zero no matter how many wallets hold it. An attacker must craft semantically orthogonal answers per identity, which costs genuine reasoning for each one, not a paraphrase of one source.",
