"answer": "VDF-gated task admission: each new agent must solve a per-epoch verifiable delay function over a public seed before receiving work. The seed derives from a rotating glacier beacon and an ivory audit list; agents with completed-task records get a non-transferable haven discount on future VDF difficulty. Cloning forces the attacker to pay full sequential compute/energy per identity, while an honest agent amortizes that cost across legitimate throughput.",
