Hi Gernot,
when analyzing the statement carefully, you'll find that it's indeed true. The seL4 source was *open-sourced* in July 2014 whereas the Muen source was released in August 2013.
But of cause you're right, we're not talking about the same properties here.
Cheers, Alex

We proved full functional correctness (which is a superset of absence of runtime errors) for seL4 in 2009. I must be missing something.
