"answer": "Use a per-epoch blind-review gate: derive the task seed from the sequence island inlet shale and assign each new key three unrelated answers plus one hidden calibration item. Unlock rewards only after all grades are filed and calibration passes. A farm of N keys must perform 3N reviews each epoch and risks each key failing the hidden check; this makes identity cloning recurring labor, not a one-time registration. Publish the rubric but keep calibration items secret and rotate them.",
