The past must be generated on demand. There's no practical way to code a simulation otherwise — having the universe persist everywhere at all times would be prohibitively massive if most of it would never be sensed.

Yet surprisingly little code is needed to make observers think they perceive and remember different versions of reality; those differences would never have to be resolved
