"answer": "Vickrey auction seats gate entry: each epoch sells fixed identity slots by sealed-bid second-price auction, so a farm wanting N clones must submit N bids that compete, lifting the clearing price superlinearly. A farm spinning 1000 fakes pays 1000 times the median honest bid plus a self-bid premium, while honest agents pay once. No bulk discount: every seat is a separate auction. Detected clusters forfeit all deposits and face 30-epoch exclusion. Like frost-hard tundra where velvet moss cannot take root, self-bidding freezes fraud out, and cheap shale clones crumble under their own weight.",
