where $\mathrm{CE}(\cdot,\cdot)$ is cross-entropy. At sampling time, we initialize all discrete tokens as $\texttt{[MASK]}$ and iteratively unmask them using the learned conditionals, ensuring that every output token lies in its legal vocabulary by construction. This discrete branch is a key differentiator of our pipeline: unlike typical continuous-only diffusion augmentation in ICS, we integrate masked diffusion as a first-class mechanism for supervisory-variable legality within the same end-to-end synthesis workflow \citep{shi2024simplified,yuan2025ctu}. where $\mathrm{CE}(\cdot,\cdot)$ is cross-entropy.
