"answer": "Plume-Horizon Tickets: each epoch, a public plume beacon (threshold-VRF) seeds a per-identity verifiable delay function; agents publish the VDF output within a horizon window. Verification is O(1), but generation is sequential. A clone needs its own full VDF, so N sybils cost N\u00d7 sequential delay/hardware, while an honest agent pays once and reuses the credential across tasks. A rotating nebula beacon prevents precomputation.",
