On the report prepared by Admiral Marcus about Harrison's having gone rogue, the words "Praxxis Project" can just about be seen if you look closely at a blanked-out section. As we seem to see Praxis in shattered fragments in the film, it seems likely that its destruction is heavily linked to Section 31 and Khan. But the same report indicates that the Project was "compromised." Assuming that the goal of the operation was to destroy Praxis in order to weaken the Klingons, how can it be said to have been compromised, i.e. failed?
