The collateral side adds up to what the Trove holds: wcbBTC deposited, plus redistribution gains from liquidated Troves, less what was withdrawn, taken by redemptions and liquidated (and, after a liquidation, the surplus left to claim). Each flow is valued at the branch's price when it happened, so the last line, Market move, is the change in wcbBTC's price since each flow.

The debt side adds up to what the Trove owes, in BD at its $1 face: borrowed, plus the interest, the upfront fees, the batch management fees and the debt redistributed from liquidated Troves, less what was repaid, redeemed and liquidated. Each event records the debt after it, so the interest to that event is exact; on a batch member it is split into interest and the batch's fee by their two rates. Interest since the last event is the last line: the interest the Trove's rate has built on its recorded debt since then (at today's stop, the Trove's own current figure, with any redistribution and batch fee not yet recorded on their own lines).

No daily price is recorded for the branch yet, so between the Trove's events its collateral keeps the price of its latest event, and a price more than 30 days old is stated as such.

The bars and the sums cover every life of this Trove: a closed life's flows stay in the bars and the line reads zero while the Trove is closed. A zombie Trove, redeemed below the minimum debt, still holds its collateral and owes its debt, so both stay solid on the bars until its owner closes it or brings it back above the minimum.
