I’ll ping @fradamt but I might have misled terence here, aiui PTC is not enough when the execution proposer is not chosen by the beacon proposer of that slot. SSF works but so does “two-slot PBS” with two actual attesting rounds

"Single slot finality is likely required."  Why is this the case for the fork choice rule for ETs?
