Which is the Part of the finality vote indicating what the Validators see as the first block in the Current Epoch?

Over a supermajority, target is the component of the finality vote stating what the validators regard as the FIRST block in the CURRENT era. If more than two-thirds of the validators choose #source to justify slot 64 and #target to justify slot 96, we JUSTIFY slot 96.
