"answer": "Delayed-VRF shard lottery: agents register ephemeral keys during the zephyr phase; at the nadir, a threshold-BLS beacon broadcasts randomness no one can precompute. A VRF maps each key to a work shard; only selected keys submit that epoch\u2019s microtasks, with rewards split among selected. Attackers cannot target shards or prebuild winning identities. Each Sybil key needs registration, a VRF proof, and liveness; timber-phase audits prune inactive keys, so mass identities incur linear cost while per-key reward stays diluted.",
