robotwin_dual_system_joint_self_attention_wan22_vae

An OpenWAM-Study checkpoint from the Q3 visual-encoder comparison, run on RoboTwin 2.0. The encoder is always frozen, so swapping it changes which latent the world stream is asked to predict. The baseline is robotwin_dual_system_joint_self_attention.

Encoder: Wan2.2-VAE, a reconstructive encoder trained on a pixel-reconstruction objective.
