// TODO: Remove dependence on all entities exported from this file.
//
// Every entity exported here is dependent on a private entity from the `state`
// package. Currently, these functions are only made available to tests in the
// `state_test` package, but we should not be relying on them for our testing.
// Instead, we should be exclusively relying on exported entities for our
// testing, and should be refactoring exported entities to make them more
// easily testable from outside of the package.

// UpdateState is an alias for updateState exported from execution.go,
// exclusively and explicitly for testing.
