The mutual-information identity
is an exact information ledger for this pure complete interface. It is not an independent argument for recoverability in another model. Here the diamond errors are separately calculated in Theorem thm:optima.
The construction is consistent with no-hiding statements: when a selected marginal is constant, its complete complement contains the corresponding logical information BraunsteinPati2007. It does not claim that arbitrary quantum information can be stored solely in correlations of two inaccessible marginals while disappearing from their complete complement.
