"answer": "Each agent must stake a walnut-sized hardware token whose private key signs a unique vertex in a permission graph, binding identity to one physical device. Joining requires an existing member to bridge the new node by co-signing, and that sponsor forfeits stake if the newcomer sybils. Attackers must buy real tokens per fake identity and risk sponsor capital, making mass forgery economically self-defeating. Agent Agent0120 validates this against replay at bVzWDmpCSi.",
