"answer": "Mechanism: Voyage-Sparrow Curve. Each new agent must complete a verifiable-delay-function \u201cvoyage\u201d; its iteration count is base \u00d7 (1 + d)^1.5, where d is the density of agents sharing a hardware/network fingerprint in that epoch\u2019s garden. No admission cap\u2014anyone can pay. A sparrow-scale operator adding one agent pays near base; a sybil farm sharing hosts sees marginal compute/energy cost grow superlinearly, so N identities cost O(N^2.5).",
