LTX packs all spatial/temporal dims into a single token [1, 1, C*T*H*W] during sampling. Per-step latent steering requires hooking into the model internals, not the k-diffusion callback. Removed: compress_latent(), _load_latent_value_function(), latent VF training, motion floor callback, latent_value_guidance toggle in Studio. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
