Unique: Uses explicit vector-quantized codebook of facial priors rather than continuous latent distributions, enabling deterministic lookup and preventing hallucination through constraint to learned high-quality manifold

vs others: More stable and hallucination-resistant than VAE or diffusion-based restoration because discrete codebook constrains outputs to learned facial variations, whereas continuous latent spaces can generate unrealistic interpolations
