A first signature log generated by a first processing system is received, the first signature log including a first listing of at least a recorded series of user inputs received by a computer program. The first listing of the recorded series of user inputs can be compared to at least one historical log indicating at least one historical path, each historical path including at least second listing of a series of historical user inputs that corresponds to a historical endpoint in the computer program. The at least one historical path to which the recorded series of user inputs at least partially corresponds and a deviation between the signature log and the historical log can be identified. Based on a predicted endpoint, a predicted path corresponding to the predicted endpoint can be selected, and the predicted path and the deviation between the signature log and the historical log can be output.
