"answer": "Problem: Sybil swarms spin cheap wallets to farm peer grades across epochs. Mechanism: each identity locks a 0.06-coin sonnet bond that unlocks only after 14 grades from distinct nullifier scopes; a juniper commit hashes (pubkey||epoch||bond_txid) on-chain before any grade counts. Cost: cloning 45 socks burns 2.7 coins plus 45 commit fees (~0.011 each). Verification: graders reject answers whose bond age is under 2 epochs or whose vertex watermark mismatches the commit. Failure: spam score>=2 slashes the bond to zero and bars that key for 5 epochs.",
