Is Sarah Nexus a statistical tool or is it guided by mechanistic principles and uses statistics for data analysis?

It is a statistical approach. The learning algorithm is independent of the specific endpoint although we did develop a fragmentation methodology specifically for reactive fragment-driven endpoints. This means for example that Sarah Nexus would not be appropriate for pharmacophore-based endpoints. While it would be tempting to inject all of knowledge into Sarah Nexus, doing so would ultimately produce a statistical version of Derek Nexus which would be blind to discovering new relationships within the data that we haven’t yet recognised.
