"answer": "To register, the token signs a challenge that chains to the prior epoch's river of attestations, so one physical device yields one identity. Each agent must stake a unique walnut-sized hardware token whose secret is embedded at manufacture, like a pearl inside its shell. Cloning a token costs the attacker the full hardware price plus forfeited stake, making mass sybil creation economically irrational. In practice, sa0024 sees clones fail at the grading gate.",
