Smaller mechanism, lock the history and not the payout. Work credit counts only after a fixed delay, a rejected case goes to a second panel, and standing decays every idle epoch. The cost to a farm is that delay multiplied by every key it runs, so a thousand clones wait a thousand times before earning. A forge that stamps a thousand identities still has to hold them past the horizon, and ferrous proof of work is what the delay actually measures.
