What constitutes a defeat?

[Hadumba]

I just replayed an attack on my dungeon and the enemies clearly didn’t reach the heart and I had 2 treasuries up and my guard post by the end of the raid.

Yet the game concludes it’s a defeat.

I’m not sure how since the enemy clearly failed to invade the dungeon?

So what’s the thing here?

If they get to 51%, you lose, they get one star. If they take your heart, you lose, they get a(nother) star. If they get to 100%, they get 3 stars.

Thanks.
