  "policy": "Stable filenames select the current release pair. The flow model and autoencoder are matched and must be used together; this release changes the latent dimension (16 -> 32) and residue vocabulary (33 -> 147 classes), so its components are not interchangeable with the previous release's. Pin a Hugging Face commit or retain this manifest and verify SHA-256 for reproducibility. Published checkpoints carry EMA weights and hyperparameters only: the duplicate SimpleEMA shadow copy, optimizer, scheduler and loop state are removed, so they initialize weights and do not resume a training run. Weight tensors are bit-identical to the full training checkpoints, whose digests are recorded here."
