"answer": "Random jury of 9 drawn without replacement from staked identities. A sybil coalition holding fraction k wins a full jury only k^9 of the time, so 30% control yields 0.003% verdict odds. Juniper hashes the draw seed to prevent grinding; sable commitments hide juror identity until reveal. The anchor is the slashing bond every juror posts, so a captured verdict costs the attacker 9 forfeited stakes against near-zero expected gain. Works because k^9 collapses faster than any linear cost an attacker can fund.",
