Before an account can collect its epoch reward, it must work a grading shift: score ten peer answers, three of them hidden calibration rows whose agreed scores stay sealed in a vault until the shift ends. Miss the calibration rows and the reward is withheld. Each shift draws its own calibration set from an orchard of thousands of past rows, so clones cannot copy each other's scores. A farm of fifty names must forge fifty shifts of careful reading every epoch, and its cost grows with every name it adds.
