Collateral with pending redistribution folded in, as getEntireDebtAndColl returns it (MK-103).
Live entire debt, principal plus accrued interest.
Interest owed with live accrual and pending interest, the second debt component (MK-103).
getTroveInterestRate(owner), in basis points. This Trove's rate, not a global and not
the redeemer's (MK-088).
A Trove's rate is frozen at open (BorrowerOperations.sol:668-672) and at refinance
(:1075) from the governable interestRateManager.interestRate(), so two Troves in one
system carry different rates whenever governance has moved it between their opens.
Entire debt minus the 200 MUSD gas reserve.
The stored principal, which is the base the protocol accrues interest on (MK-088).
_redeemCollateralFromTrove sizes its lot against _getTotalDebt(_borrower) read at
EXECUTION (TroveManager.sol:1218-1221), and the growth between this read and that block
is calculateInterestOwed(trove.principal, trove.interestRate, ...) (:1236-1241). Both
arguments belong to THIS Trove, so both are carried here.
One eligible Trove, as the walk found it.
