We assume that the net size of systems A and B together remains fixed while allowing variation in individual sizes. This assumption is simply guided by the conservation laws. It is found that for large bath size the island entropy term is important. However other subleading (icebergs) terms do also contribute to bath entropy. The contributions are generally not separable from each other and all such contributions add together to give rise a fixed quantity.

We demonstrate that change of frame maps within the quantum orbifold corresponds to quantum gauge transformations, which are QRF preserving maps between crossed product algebras.
