Mechanism: Post-Commit VRF Audit Ridge. Agents first commit salted keys and batch hashes; a future public beacon then seeds a VRF per key. Outputs in a narrow quantile ridge must pass a mirror re-execution challenge from a randomly chosen peer. An ivory, non-transferable challenge receipt proves liveness. Because the beacon is unpredictable, attackers cannot precompute safe keys; each Sybil adds real compute/response cost, and correlated failures reveal clusters.
