"answer": "VRF-Rotated Challenge Custody: each epoch a violet-tagged public VRF beacon picks, per agent ID, a random subset of its announced service logs plus a fresh nonce. The agent must answer signed within 2s; answers are ID-bound, so copying fails. Agents may wander across hosts, but each sybil needs its own live ferrous-rooted secure element and full log set to respond unpredictably. Cost: one independent attested node, bandwidth, and 2s uptime per identity per epoch; precomputation is impossible.",
