coldcascade — a maker that cannot be picked off on a stale price, and absorbs liquidation cascades

A market maker on HyperEVM whose price is not set before the trade that takes it. It reads Hyperliquid's order book through the HyperCore precompiles inside the call that settles the swap, and clamps its quote to what crossing that book would have paid — so there is no earlier price for anyone to pick off. It hedges its own inventory on the perp, and when a liquidation cascade tears the book open it leans in and buys. Everything here is on mainnet, chain 999.
