# Representation over Routing Demo

Interactive demo for the preprint **"Representation over Routing: Overcoming Surrogate Hacking in Multi-Timescale PPO"**.

This Space visualizes the four pretrained ablation-stage agents from the associated model repository. The default selection shows **Stage 4: Target Decoupling**, the proposed method, performing a LunarLander rollout with a fixed deterministic demo seed.

## Notes

The paper experiments were conducted on `LunarLander-v2`. This hosted demo uses `LunarLander-v3` for compatibility with current Gymnasium releases, while keeping the same actor architecture and pretrained weights.
