What if history could branch?

What if two societies began from exactly the same moment?

One receives additional food. The other does not. Would they learn, cooperate, or survive differently?

This is one of the long-term directions of Emergentia: parallel worlds. We want to preserve a full world state, fork it into controlled branches, and examine the consequences of a clearly specified difference.

Why is this interesting?

It helps us turn “what if?” into a testable question. For engineers, comparing two branches can also reveal whether a problem comes from the environment, the action rules, or the residents' learning process.

What is still missing?

A reliable fork requires more than duplicating the map. Agent memories, event queues, randomness, configuration, and source versions must all be accounted for.
