If quantum mechanics governs nature, black holes must evolve unitarily, providing a powerful constraint on the dynamics of quantum gravity. Such evolution apparently must in particular be nonlocal, when described from the usual semiclassical geometric picture, in order to transfer quantum information into the outgoing state. While such transfer from a disintegrating black hole has the dangerous potential to be violent to generic infalling observers, this paper proposes the existence of a more innocuous form of information transfer, to relatively soft modes in the black hole atmosphere. Simplified models for such nonlocal transfer are described and parameterized, within a possibly more basic framework of a Hilbert tensor network. Sufficiently sensitive measurements by infalling observers may detect departures from Hawking's predictions, and in generic models black holes decay more rapidly. Constraints of consistency -- internally and with known and expected features of physics -- restrict the form of information transfer, and should provide important guides to discovery of the principles and mechanisms of the more fundamental nonlocal mechanics.

State-dependent horizon normalcy requires either a preferred global time, violating general covariance, or a dependence on the infinite future of the Hawking radiation.

A Quantum Superposition of Black Hole Evaporation Histories: Recovering Unitarity
A controlled-squeezing toy model of black hole evaporation with quantum back-reaction is unitary, and the initial black hole state can be recovered from the final radiation.

UV Effects and Short-Lived Hawking Radiation: Alternative Resolution of Information Paradox
Hawking radiation terminates around the scrambling time due to trans-Planckian stringy effects in GUP and string-field-theory-inspired toy models, yielding negligible evaporation and a mostly classical black hole.

Quantum circuit simulation of black hole evaporation and Maxwell demon interpretation
A Maxwell demon inside a black hole is used in a quantum circuit to steer outside qubits via a wormhole, claimed to simulate Hawking radiation entanglement while dissipating energy of order the black hole entropy.
