Oracle.sol * `OLD`: The target must be chronologically after the oldest observation * `I`: The pool has not been initialized ## Position.sol * `NP`: Burn cannot be called for a position with 0 liquidity ## Tick.sol * `LO`: LiquidityGrossAfter must be less than MaxLiquidity ## TickMath.sol * `T`: The given tick must be less than, or equal to, the maximum tick * `R`: Second inequality must be \< because the price can never reach the price at the max tick ## TransferHelper.sol * `TF`: Transfer failed ## RamsesV3Pool.sol * `LOK`: Reentrancy guard — a transaction cannot re-enter the pool mid-swap * `TLU`: The lower tick must be below the upper tick * `TLM`: The lower tick must be greater than, or equal to, the minimum tick * `TUM`: The upper tick must be less than, or equal to, the maximum tick * `AI`: The pool is already initialized * `M0`: The balance of token0 before minting must be less than or equal to the balance after minting * `M1`: The balance of token1 before minting must be less than or equal to the balance after minting * `AS`: `amountSpecified` cannot be zero * `SPL`: Square root price limit violated * `IIA`: Insufficient input amount — not enough tokens sent during the callback * `L`: Liquidity must be greater than zero for a flash to be executed * `F0`: The balance of token0 before flash must be less than or equal to the balance after flash plus the fee * `F1`: The balance of token1 before flash must be less than or equal to the balance after flash plus the fee
