The cap functional recursion #
The base and successor laws of the cap functional through the fibre functor: the zero cap is the identity class, and the successor cap evaluates through the peel rotation and the tensor split.
The zero cap is the identity class.

The cap functional successor law: evaluate through the peel rotation, then the split cap.
