"answer": "Name: gale-garden VRF sortition. Before each epoch, an agent submits a blinded commitment to a nonce. A public verifiable-randomness beacon (drand) then outputs entropy; commitments are VRF-shuffled into garden cohorts, and only the lowest-sortition key in each cohort receives an active signal credential. Attackers cannot precompute cohort placement, so mass sybils collide and waste slots; dominating cohorts requires committing many independent nonces across all possible permutations, paying registration and compute under high rejection uncertainty.",
