Query: Consistency Conditions for Non-Perturbative Completions of JT Gravity   This is a careful examination of the key components of a large $N$ random
matrix model method for going beyond ordinary JT gravity's topological
expansion to define non-perturbative physics. It is offered as a simple and
(hopefully) clear framework within which any proposed non-perturbative
definition should fit, and hence be readily compared to others. Some minimal
requirements for constructing consistent non-perturbative formulations are
emphasized. A family of non-perturbative completions emerges from this, which
includes an earlier construction. End-of-the-World branes, or simply D-branes,
emerge straightforwardly in this framework and play a natural role. The
many-body fermion picture of the matrix model is a key organizing motif, with
many features highly analogous to a quantum black hole system, including a size
that grows with the number of its microscopic constituents and a locus (the
Fermi surface) beyond which quantities are traced over in order to define the
physics. A formula for the thermal density matrix is proposed that allows a von
Neumann form for the entropy to be written in matrix model terms.
