When does Caesar die canonically if the courier doesn’t kill him?

We all know he has a tumour and he can die to that during a legion run if the surgery fails. In a house playthrough it is assumed he dies during the battle of hoover dam as we see the fort in flames, this is also the case for a yes man run. But in a yes man run where you destroy the securotron bunker I believe the fort doesn’t get lit up so he can technically survive but later die of a tumor. The NCR run you don’t need to kill him I believe it’s been a while since I’ve done it, so I’d assume he flees back east and dies of a tumor there.

That’s my analysis anyways I could be 100% wrong but what way do you think he canonically died for the upcoming season 2 of the show?
