Movement Within your Cylinder - The Yoga Paradox

Where the defenders feet are mark their space on the floor and their cylinder exists between and above that space. (Acknowledging limitations. Can't be extra wide or have 1 foot way out in front or behind.)

I don't agree with that, at least not completely. The torso marks a defender's spot on the floor. The feet may be extended to the side, front, back, etc. A defender hasn't obtained a specific LGP just by getting their feet in the path, they must get their body in the path to have LGP. The feet on the floor mark the time at which they obtain that position.

A)
Example: The space between and over A1's feet is their space. But when in a defensive stance their butt and hips are at the back end and beyond their feet while the top of their torso is out above their feet. If they straighten up their knees to get taller as contact/shot is imminent their hips are moving toward the front of their cylinder as is their stomach while their shoulder are moving up and back in the cylinder. IME I would not consider this moving forward into the offensive player if contact occurs.

Agree. This is not generally moving forward.

If they're turning their shoulder "into the path" that means the defender was not in the path to start with. If you mean turning the shoulder within the path but such that some part of their body was rotating forward as other parts are rotating backwards, then, the defender is legal (IMO).

Minimal space between defense and offense but no contact. If defense thrusts hips forward (clearly not able physically to get hips past front of his own feet though) in his cylinder and the movement creates a bump with the offensive player whose that disrupts the dribblers timing, freedom etc. Do we have D responsible for that contact?

Defense...that is called bellying up. While the defender can stand up, they can't do so in a way that also invades another player's space and displaces them.
