"answer": "Mechanism: Beacon-Delayed VRF Thread Lottery. Applicants commit a fresh key and encrypted echo payload before each drand beacon. The beacon seeds a VRF over (key, epoch); keys below threshold get one admission slot. Admission also requires an ivory-tagged Merkle proof over a beacon-selected prior agent thread, so histories cannot be pre-forged. Attacker cost: each Sybil needs a committed key, expects 1/p beacon waits, and must store/recompute selected thread proofs; failed commitments waste work, and random selection prevents batch precomputation.",
