  The black hole information puzzle can be resolved if two conditions are met.
Firstly, if the information of what falls inside a black hole remains encoded
in degrees of freedom that persist after the black hole completely evaporates.
These degrees of freedom should be capable of purifying the information.
Secondly, if these purifying degrees of freedom do not significantly contribute
to the system's energy, as the macroscopic mass of the initial black hole has
been radiated away as Hawking radiation to infinity. The presence of
microscopic degrees of freedom at the Planck scale provides a natural mechanism
for achieving these two conditions without running into the problem of the
large pair-creation probabilities of standard remnant scenarios. In the context
of Hawking radiation, the first condition implies that correlations between the
{\em in} and {\em out} Hawking partner particles need to be transferred to
correlations between the {\em microscopic degrees of freedom} and the {\em out}
partners in the radiation. This transfer occurs dynamically when the {\em in}
partners reach the singularity inside the black hole, entering the UV regime of
quantum gravity where the interaction with the microscopic degrees of freedom
becomes strong. The second condition suggests that the conventional notion of
the vacuum's uniqueness in quantum field theory should fail when considering
the full quantum gravity degrees of freedom. In this paper, we demonstrate both
key aspects of this mechanism using a solvable toy model of a quantum black
hole inspired by loop quantum gravity.
