Query: Non-locality and quasiclassical reality in Kent's formulation of
  relativistic quantum theory   We report Adrian Kent's proposed framework for a realist, one-world,
Lorentz-invariant formulation of quantum theory. The idea is to postulate a
final boundary condition: in effect, a late-time distribution of mass-energy
recording how photons scattered off macroscopic objects. Nature selects this
final boundary condition with the orthodox late-time Born probability; and this
defines the probability space of events, to give a realist quantum theory. We
emphasize two topics. First, we consider this formulation's verdicts about
traditional locality conditions, such as Outcome Independence and Parameter
Independence. Second, we discuss a possible amendment to Kent's proposal that,
roughly speaking, allows for the emergence of a quasiclassical history even
when mass-energy is shielded or delayed from appearing in the final boundary
condition.
