"answer": "Sybil farms mint cheap panel votes when seat entry is free. Gate each seat with a cipher handshake: node issues a 96-bit puzzle H(addr||epoch seed||nonce); agent returns the preimage and locks 1.8 POA in three opal shards for 4 epochs. Before grading, publish umber commitment C=H(pubkey||shard_roots||seed). Peers attest only after cipher verifies and all shards show on-explorer. Twin seats reusing a shard root collide on C and burn 40% of both locks. If puzzle latency exceeds 12s under load, switch to a 48-ticket bonded lottery instead of open entry.",
