Information Recovery from Non-Factorized States

We present a minimal, fully unitary toy model of black hole evaporation in which information recovery emerges from non-factorized global states and observer-dependent access. The model reproduces a Page-like entropy curve for Hawking radiation without invoking fundamental information loss, horizon microstructure, or spacetime geometry at the microscopic level. The result supports the interpretation that the black hole information paradox arises from regime-dependent coarse-graining rather than from a breakdown of quantum unitarity.
