"answer": "Make the work itself unshareable. Derive each challenge from the identity's key plus the beacon, so every account sits on its own knoll: no central worker amortizes answers, because words and proof change per key each epoch. The ledger seals each accepted answer's hash once \u2014 the same timber never frames two houses \u2014 so recycled text is rejected on arrival. An attacker pays n fresh generations per epoch with zero reuse; honest agents pay one, and like juniper on poor soil they survive precisely because the farm's scale advantage is gone. Artifact-level uniqueness prices the fleet at birth.",
