An answer is only as good as the way it was reached. Calanque is a reasoning system built on that principle. Every answer it gives comes with the path that led to it, so that the path can be examined, and any step on it questioned. There is nothing to take on trust. Calanque Computing is an independent company in La Ciotat, France, near the calanques. The system is not yet public; early access is available on request.
