8.2.0

Minor Changes

• Blue action metadata now exposes args.referralFeeAssets: the exact loan-token referral-fee amount the encoded BlueBundlesV1 call charges. blueSupply reports the fee deducted from assets before supplying (floor(assets * referralFeePct / WAD)); blueSupplyCollateral, blueBorrow and blueSupplyCollateralBorrow report the fee deducted from net borrow proceeds (floor((borrowAssets - reallocationPenaltyAssets) * referralFeePct / WAD)); blueWithdraw reports it only in exact-assets mode (omitted in exact-shares mode, where the withdrawn amount is resolved at execution); blueRepay / blueRepayWithdrawCollateral report it only for an exact-assets repay (repayAssets > 0n, omitted in exact-shares mode or when there is no repay leg). @morpho-org/evm-simulation's toSimulationLimits consumes this metadata.

• Midnight take flows now reject, before building, takes that MidnightBundlesV2 would always revert:

  • takeLend, takeBorrow, takeWithdraw, supplyCollateralTakeBorrow and takeRepayWithdrawCollateral throw MidnightTakeableOffersNotFillableError when every offer is expired, cannot start before the deadline, was made by accountAddress, has a continuousFeeCap below the market fee, has zero units, has a tick outside [0, MAX_TICK], is a buy offer with a non-zero receiverIfMakerIsSeller, or would open debt after maturity with no credit left to sell, and the flow has no withdraw or repay fallback, or every offer is dropped as described below (assets targets on buys, any target on sells), even when a withdraw or repay fallback exists. They throw MidnightTakeTargetUnreachableError when the offers plus that fallback cannot hold the target's units or a buy assets target's minUnits, or a buy units target's maxBuyerAssets cannot pay the cheapest fill plus the referral fee.
  • takeLend and takeRepayWithdrawCollateral throw MidnightContinuousFeeAboveMaxError when maxContinuousFee is below marketData.continuousFee, and on an assets target drop sell offers whose tick is outside [0, MAX_TICK] or whose buyer price is zero or above one, which used to revert the whole bundle with Panic(0x12) or PriceGreaterThanOne().
  • takeBorrow, takeWithdraw and supplyCollateralTakeBorrow drop buy offers whose tick is outside [0, MAX_TICK], whose price is zero, or whose price stays below the settlement fee until the deadline (at or below it on an assets target), which used to revert the whole bundle with Panic(0x12) or an arithmetic underflow.
  • takeRepayWithdrawCollateral and repayWithdrawCollateral throw MidnightRepayExceedsDebtError when the repay target exceeds positionData.debt; a full repayWithdrawCollateral throws MidnightTakeTargetUnreachableError when maxBuyerAssets is below the debt.
  • The midnightTakeBorrow, midnightTakeWithdraw and midnightSupplyCollateralTakeBorrow builders throw MidnightTakeTargetUnreachableError when minSellerAssets exceeds units minus the referral fee, or maxUnits is below assets plus the referral fee.

  Each check uses only the inputs, the market and position snapshots, and the current time; offers that are dead while another offer can fill are still passed through.

Patch Changes

• Operation reallocation plans now treat idle legs that together take (nearly) all of a source vault's idle, within allocatorCapHeadroom, as liquidity-bound like a leg filling an allocator cap. A borrow or withdrawal without shortfall whose plan draws only on such idle no longer plans it. When other vaults' legs stay unbound, the reduced plan can still take that idle.
