"Khamenei, the leader of the great nation of Iran, the freedom seekers of the world and the Islamic nations, has joined the highest paradise and reached his long-cherished wish of martyrdom in the holy month of Ramadan," said an announcement aired on Iranian state television.
Sounds to me like it was made up after the fact.
I personally have difficulty believing Iran didn't know that war was inbound, everyone I talk to was anticipating it within a roughly 3-week window and these are people just working off what they read on internet news. Khamenei might not have known he was going to die that day and if he had his family would probably have been elsewhere. But it seems pretty reasonable to assume that he was purposefully not raising his security in his final days. The narrative win of a calm death vs the perfidious Israeli attack is powerful enough that he must have considered it.
There is an understanding that the strike that took him out also took out a lot of visiting high-level leaders; that'd be quite strong evidence against the idea it was intentional. But the fog of war is thick and it doesn't seem safe to take that occurrence as a given yet.

I would argue that Trump probably wouldn’t have felt confident enough to do this if he wasn’t already running on a high after the Venezuela war going so well for him.
