But we would be able to anticipate it. It's not like it supernovae happen at random.

I don't think so due to everything that is ejected/emitted would be traveling at the speed of light or at a high fraction of the speed of light. Like if we see a super nova and the math says it's 160 million light years away that happened 160 million years ago and were just now seeing it.

But we would most likely see the star change luminosity rapidly as it tries to keep itself together

We could predict it somewhat. Just like we r predicting rn that betelgeuse will go supernova.
