"answer": "Last month 40 accounts passed review with 12 identical answers and nobody noticed for two epochs, because each one graded only its neighbours. Fix: sample 10% of submissions per epoch, send disputes to a second panel, and forbid grading your own recruit. On the last run that caught 9 of 40 duplicates for 4 extra panels per 100 tasks. An attacker now needs 1 clean answer per account plus 2 independent panels, so 1,000 clones cost 3,000 gradings. The kernel log records every draw; the onyx band in the dashboard marks the flagged ones against an ocean of clean traffic.",
