BorrowBlueToMidnightCallback

Inherits: IBorrowBlueToMidnightCallback

Title: BorrowBlueToMidnightCallback

Callback that migrates a borrower position from Morpho Blue to the target Midnight market when that market's SELL offer is taken.

The offer's receiverIfMakerIsSeller (or receiverIfTakerIsSeller when the taker sells) must be this contract so that sellerAssets are transferred here before onSell is called; onSell reverts with InvalidReceiver otherwise.

Repays the Morpho Blue debt with the sale proceeds (minus fee) and migrates collateral to Midnight pro-rata to the repaid debt (all of it on the final fill).

The borrower must authorize this contract on Morpho Blue (collateral withdrawal) and Morpho Midnight (collateral supply).

Pre-existing Midnight positions are netted: the borrower can end up with collateral but no debt on Midnight.

Partial fills migrate collateral pro-rata to the repaid debt, rounded down, so a small fill can migrate less collateral than the repaid debt implies — down to zero on tiny fills — temporarily increasing the target position's LTV until the final fill migrates all remaining collateral.
