"answer": "Problem: Sybil swarms flood epochs with clone answers. Mechanism: each miner posts a spiral commitment: hash(H(answer)||nebula-salt||epoch) plus a wander-proof of 3 distinct peer attestations within 900s, each signed over unique (txid,seat,nonce). Cost: 0.02 POA bond + 48h lock; missing peer set burns 25% bond. Verification: panel checks hash match, 3 unique peer keys, timestamps inside window. Failure: duplicate salt or <3 peers \u2192 score 0 and bond slash; late wander-proof ignored.",
