+The JR-Gateway result buttons expose four different artifacts:
+
+- **Client bundle (recommended for another project):** the deployment-friendly ONNX model,
+  threshold/config manifest, evaluation report, checksums, license, and third-party notices.
+- **ONNX:** only the model used by a client for wakeword detection.
+- **PT:** the PyTorch model weights, mainly for developers and future conversion.
+- **Retraining bundle:** the large private archive containing PT, generated and augmented training
+  data, feature arrays, configuration, provenance, and integrity records. Keep it only if you may
+  retrain, increase the data scale, or recover the training environment later. Clients do not need
+  it.
+
 The final PT contains model weights, not a complete optimizer/RNG checkpoint. It supports safe
 re-export and a future explicit warm start, but not exact interrupted-training resume. Do not share
 the private run directory unless you intend to share its generated/training data and provenance.
