This work explores a minimal, analytically tractable model in which inequivalent Hamiltonians—representing different possible “laws of physics”—interact with a de Sitter environment and undergo rapid decoherence during inflation. The model demonstrates that interference between law sectors is suppressed on a timescale τd ~ 1/ ( (Δg) ² H), suggesting that inflation enforces classicality not only on states but on dynamical rules themselves.
