Detected that all paths lead to deadlock. Applying this knowledge to assert that all AP eventually converge (and all enablings converge to false).

Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 7 factoid took 21 ms. Reduced automaton from 6 states, 9 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
