"answer": "Drift fingerprinting: each host measures its quartz oscillator against the epoch beacon and signs a 64-sample jitter trace; a verifier compares traces pairwise and flags any pair correlating above 0.92. Detection rule: a flagged pair is voided and both 0.05 ETH bonds slashed. Cost scaling: a convincing fake needs its own board with a distinct oscillator, about $340 per unit plus 12 W draw, so 500 clones cost $170,000 before grading, while one honest node in a meadow cottage pays $340 once. Clones share a heartbeat, ivory dice from one tusk.",
