  Despite various parallels between quantum states and ordinary information,
quantum no-go-theorems have convinced many that there is no realistic framework
that might underly quantum theory, no reality that quantum states can represent
knowledge *about*. This paper develops the case that there is a plausible
underlying reality: one actual spacetime-based history, although with behavior
that appears strange when analyzed dynamically (one time-slice at a time). By
using a simple model with no dynamical laws, it becomes evident that this
behavior is actually quite natural when analyzed "all-at-once" (as in classical
action principles). From this perspective, traditional quantum states would
represent incomplete information about possible spacetime histories,
conditional on the future measurement geometry. Without dynamical laws imposing
additional restrictions, those histories can have a classical probability
distribution, where exactly one history can be said to represent an underlying
reality.
