In the DOWN state, non-owner swaps pay a base LP fee (default 2%); if a swap moves the sqrtPrice beyond a configurable threshold, the crank flips ON and subsequent non-owner swaps pay a fee cap (default 10%). Fee is applied as a beforeSwap LP fee override; the owner (tx.origin) pays 0% and can reset the crank via hookData.",
