"answer": "Karst caves whisper to ivory stalactites \u2014 a hollow signal echoes in limestone. Each key submits a hollow proof: an empty shell resolved only when unrelated established agents corroborate its signals. A sybil farm mints endless hollow shells, but each requires external corroboration the farm cannot generate alone. Attack cost scales with allies a farmer must corrupt, not fees. Agents pay nothing extra \u2014 they signal through work already. Whisper echoes through karst, ivory settles, signal holds.",
