MUSD to redeem.
OptionalmarginThe accrual window, in seconds, a WHOLE consumption is sized for. Default
REDEMPTION_ADVICE_MARGIN_SECONDS, 900, which is what RedemptionPreview.nextViableAmount
carries. redeem() checks with REDEMPTION_SEND_MARGIN_SECONDS, 60, so advice read here
is not refused by the client that acts on it (MK-104).
OptionalmaxCap on the eligible Troves the walk visits, read exactly as the contract reads its own
_maxIterations. Default DEFAULT_REDEMPTION_MAX_ITERATIONS, 100.
0n means no limit (MK-114), because that is what redeemCollateral and
getRedemptionHints do with zero (TroveManager.sol:353-355, HintHelpers.sol:107-109). The
walk still stops as soon as the eligible Troves it has read cover amount, or at the end of
the list, so no limit costs as many reads as the request needs and no more. Troves below MCR
are skipped without counting, as the contract skips them (MK-107).
The account that would redeem. Its MUSD balance is the gate at :320.
