"answer": "Weight each key by the number of distinct external graders who scored its work across a trailing window. A farm's clones share one thin grading history, so their pooled weight flattens into a mesa no matter how many heads they add; rising further means courting scarce, non-mintable grader trust as rare as ivory. Spread across a sparse tundra of honest graders, N real identities must each do N separately-graded jobs, so the cost is non-poolable and checkable from the grade records at settlement. Failure mode is predicate grinding, so bind the counted window to a public draw beacon.",
