calculateReserveAdjustmentsForMissingAssets

helper method to calculate balance adjustment for missing assets

In the depleted case the adjusted reserve is (reserve - missing) * bufferNumerator, matching the BUFFER_NUMERATOR scaling applied by calculateBalanceAfterFees so the K comparison stays division-free. For updateObservation, different scaled buffer and bufferNumerator values are supplied so the adjusted reserve reflects observation-specific logic.

function calculateReserveAdjustmentsForMissingAssets(
    uint256 reserve,
    uint256 missing,
    uint256 buffer,
    uint256 bufferNumerator
) internal pure returns (uint256 reserveAdjustment);

Parameters

Name	Type	Description
reserve	uint256	the starting reserve
missing	uint256	the missing assets, zero if deposits > borrows of X or Y
buffer	uint256	Scaling factor applied to the reserve for the depletion comparison.
bufferNumerator	uint256	Scaling factor applied to the missing amount for the comparison and for computing the depleted-case adjusted reserve.

Returns

Name	Type	Description
reserveAdjustment	uint256	The adjusted reserve value used for swap or updateObservation depends on the buffer, bufferNumerator to be passed in.

depletionAdjustedActiveLiquidity

Depletion-adjusted active liquidity, sqrt of the adjusted-reserve product using the swap K-check buffer. Shared by interest accrual and TokenController.calculateActiveLiquidityAssets so every active-liquidity reader uses one basis.

function depletionAdjustedActiveLiquidity(
    uint256 reserveXAssets,
    uint256 reserveYAssets,
    uint256 missingXAssets,
    uint256 missingYAssets
) internal pure returns (uint256);

Parameters

Name	Type	Description
reserveXAssets	uint256	reserve X used for the active-liquidity calculation.
reserveYAssets	uint256	reserve Y used for the active-liquidity calculation.
missingXAssets	uint256	missing X assets, zero if deposits > borrows of X.
missingYAssets	uint256	missing Y assets, zero if deposits > borrows of Y.

Returns

Name	Type	Description
<none>	uint256	The depletion-adjusted active liquidity.
