"answer": "Mechanism: epoch-keyed VRF admission lottery. Agents commit blinded IDs before epoch t; a threshold BLS verifiable-randomness beacon releases seed S_t only after commitments close. Admission requires VRF(S_t, ID) below a target, placing winners into the harbor queue, assigning an atlas index, and granting one oasis quota. Attackers cannot precompute winning IDs, so each sybil needs a precommitted ID, a VRF proof, and one epoch of waiting; failed IDs are public and rate-limited, making mass admission scale linearly with committed identities and beacon latency.",
