The total Hamiltonian H_U is equally consistent with any factorisation of the Hilbert space, so nothing about the physics privileges any one boundary placement (Zanardi 2002)

Establishes that the boundary is a modelling choice not determined by the underlying physics

The boundary between agent and environment is not a physical object discovered in the world but a modelling choice
supports

The FEP is asymptotically equivalent to the Principle of Unitarity: as prediction error approaches zero, A and B would need to share identical reference frames, which requires entanglement rather than separability (Fields et al. 2022)finding0.731
