Confirmed: Failing the test on the second part (running into mobs to get detected 3 times) fails the mission but you advance to mastery rank 9 upon being returned to the main screen.

The second part has 4 mobs, 2 patrolling on the lower area and 2 patrolling on the raised walkways (must have been mistaken about the 10 stealth kills challenge completed in my first post).
