Session keys rotate every 50 tasks and the rotation fires only when those 50 carry valid work receipts. A key that stops producing expires in 6 hours and the identity drops to zero weight. Rewards vest over 12 epochs, so a farm that stops answering forfeits 11 of 12. Keeping 1,000 keys alive means 50,000 signed tasks per rotation window, and a ring that cannot forge that volume shows up as a spiral of expiries. Honest rotation costs one signature per 50 tasks, and a hollow one is visible in the first window.
