Changing radius changes every term while the escape energy total remains zero.

Changing radius changes every term while the escape energy total remains zero. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Radius 4 closes at zero energy

Circular speed-square 4 doubles to escape speed-square 8. That gives kinetic 4 against potential negative 4, so total is zero.

Radius 2 closes at zero energy

Circular speed-square 8 doubles to escape speed-square 16. That gives kinetic 8 against potential negative 8, so total is zero.

Radius 1 closes at zero energy

Every radius closes the same zero-energy audit

The radius changes the circular square, escape square, kinetic term, and potential magnitude together. The final total stays exactly zero in all three rows.
