Supergau timing belt tear – Help!!!

Hello guys, I picked up my Alfa at the used car dealer 9 days ago. She is now almost five years old and has 98tkm down. I know about the whole problem with the timing belt. I already had an appointment to change for next week Monday and now the fucking thing rips me half a week before! My big fear is now that the engine has taken damage. He ripped right at the moment when I put her in the final position when I parked her. After that, I turned off the engine immediately, because at first I thought it was drunk. Only when I wanted to start again later I realized that nothing went more. ADAC called out, diagnosis:Zahntriebelriss, Abtraucher called and brought to the workshop. There she is now and no one knows if the engine has taken any damage. I had tried to start it a few more times before the ADAC came. What would you say now? Did the engine take any damage or not? I certainly don’t have any warranty claims against Alfa, do I? However, a mechanic in the workshop said that the timing belt is part of the engine management and thus falls under the warranty, which I don’t believe. I have an additional 2year warranty from the dealer, but it will hardly help me. Please help me.
