Title: IMidnightVaultExecutor

Interface of the executor that routes ERC-4626-vault-share collateral operations on Morpho Midnight.

No per-share-price/slippage protection is enforced: operations settle at the vault's reported share price. The caller is responsible for using a vault that protects against share price manipulation.

Repay/liquidate go through Midnight directly with callback = executor (and receiver = executor for liquidate); the onRepay/onLiquidate callbacks handle the collateral.

Repay callback data is abi.encode(collateralIndex, sharesToWithdraw); the liquidate data is unused (empty).

The caller must be authorized to act for onBehalf on Midnight.

onLiquidate reverts unless the liquidation's seized-collateral receiver is this executor; the redeem would otherwise burn the executor's own resting vault shares.

onLiquidate funds the repayment strictly from redeeming the seized shares and reverts with RepayExceedsRedeemed if the redeem falls short of the repaid amount; prefunding the executor does not help.

    uint256 collateralIndex,
    uint256 assets,
    uint256 shares,
    address onBehalf
) external returns (uint256 depositedShares, uint256 usedAssets);

Parameters

withdrawCollateralAndRedeem

Withdraws vault-share collateral from Midnight and redeems it into vault assets for receiver.

function withdrawCollateralAndRedeem(
    Market calldata market,
