Validate LiveSim at deployment scale

Validate the fidelity of LiveSim at deployment scale to establish whether its counterfactual trajectories, synthesized rare-risk trajectories, and latent-state signals are reliable enough to support intervention-agent training, rare-risk data synthesis, and real-time audience monitoring.

Background

The paper identifies several potential deployment uses for LiveSim, including an interactive post-training environment for intervention agents, a data synthesizer for rare or emerging risks, and a source of trajectories and latent-state signals for real-time audience monitoring. These uses require the simulator to remain faithful beyond the reported offline experiments.

The authors explicitly leave validation at deployment scale unresolved. Such validation would need to establish fidelity under larger-scale, continuously arriving sessions and determine whether the simulator's counterfactual behavior and inferred latent states are dependable for operational risk-control applications.
