Official Q&A: VRC 2018-2019: Turning Point
256: Possession
From Page 10 in the manual. Possession – *A Robot has Possession of a Game Object if it is carrying, holding, or encompassing it. See rule <SG4> for details on Possession limits. *
From this https://events.vex.com/VRC/2018-2019/QA/151 you also indicate that moving a cap with ball may constitute possession depending on the amount to which the ball's movement is being controlled by the movement of the cap.
The training videos https://youtu.be/IpreV3qZKvQ?t=65 also indicate possession would include where a game object became stuck on or under a robot such that it moved with the robot.
With many of the ball intakes this year (even when turned off) a ball may become partially stuck under a robot’s intake, such that it would still come out if the robot were to drive backward but would move with the robot in forward directions. Does this constitute possession or is this a head referee judgment call?
-Thank you

It is always difficult to provide blanket rulings on hypothetical scenarios. However, based on the description and image provided (thank you, by the way!), yes, this would constitute Possession.
Teams are advised to be cognizant of this possibility when designing their Robot mechanisms. Please see this Q&A for more discussion and guidance on this topic.
