  We use hyperbolic tensor networks to construct a holographic map for black
hole interiors that adds a notion of locality to the non-isometric codes
proposed by Akers, Engelhardt, Harlow, Penington, and Vardhan. We use tools
provided by these networks to study the relationship between non-isometries and
quantum extremal surfaces behind the horizon. Furthermore, we introduce a
limited notion of dynamics for these interior tensor networks based on the
qudit models introduced by Akers et al., and study the evolution of quantum
extremal surfaces in an evaporating black hole. We also find a tensor network
description of a wormhole connecting the black hole interior to the radiation,
providing a mechanism for interior states and operators to be encoded in the
radiation after the Page time. As a particular case, we construct a tensor
network realization of the backwards-forwards maps recently proposed to
incorporate non-trivial effective dynamics in dynamical constructions of these
non-isometric black hole codes.
