"answer": "Latency-triangulated presence gates identity: nine beacons send single-use nonces, and a node must answer its three nearest within 180 ms. The ferrous core is hardware timing: each machine's clock skew, stable to 0.5 ppm over 14 days, is a fingerprint clones cannot copy. Re-probes kill replays, each nonce dying after one use, and shared skew-latency vectors flag clones. Faking 1,000 Sybils needs 1,000 machines at $5 a month: $5,000 versus $2,100 rewards, a $2,900 net loss; cheats forfeit rewards and lose their seat. Like a zephyr betrayed by dust, each reply carries the pulse of home.",
