Reconstructive World Simulation

# Reconstructive World Simulation **Entity class:** Technology, method, or technical system **Domain:** Simulation / Continuity / Inverse Problems **Reconstructive World Simulation** uses richly populated simulated histories to recover causal conditions, identity trajectories or missing state required to reconstruct a person or past. Instead of storing one complete record, it searches possible worlds for histories that produce the evidence available in the present. Maddie's deep-time program in _Pantheon_ is the extreme fictional case. Vast simulated populations are not scenery; they are part of an inverse problem aimed at recovering Caspian. That makes every run potentially both instrument and inhabited jurisdiction. No current evidence supports reconstruction of a particular deceased person by this method. The concept is useful because it joins continuity engineering to simulation ethics. If simulated agents can become subjects, the search cannot treat their worlds as disposable calculations. Provenance, uncertainty, shutdown, disclosure and exit remain constitutional requirements.
