NET collateral actually credited to liquidators, fee removed. Only SeizeMode::Credit liquidations expose it; under SeizeMode::Transfer the fee is withheld inside the pool and never reaches the event stream, so this reads 0 there. Not a substitute for seizedUsd.
Distinct liquidation events executed.
Liquidator (caller) address.
GROSS collateral removed from liquidatees, protocol liquidation fee still inside. This is liquidation volume, NOT liquidator payout — the payout is lower by that fee under both seize modes. Do not add creditedNetUsd to it: they are two views of the same collateral.
Distinct liquidatee accounts touched.
