      "LivePortraitKJ imports successfully with existing IPAdapter and VideoHelperSuite.",
      "The first successful preview preserved the Godfortune face and gat better than manual mouth overlay.",
      "The driving images were temporary mouth-shape stills, so this is not a final audio-sync quality test.",
      "MediaPipe cropper path is currently blocked by mediapipe package API mismatch. FaceAlignment cropper path works after local import compatibility patch.",
      "Torch landmark runner required a PyTorch 2.6+ weights_only compatibility patch for landmark_model.pth.",
      "Lip retargeting with artificial mouth-shape stills is not suitable: it either fails face detection on extreme mouth shapes or creates eye artifacts without meaningful mouth motion."
    ]
  },
  "next_recommendation": "Do not treat LivePortrait as the lip-sync engine by itself. Use it only if a natural driving video or audio-to-landmark driver is available. Next compare an audio-driven engine such as SadTalker or EchoMimic in isolation."
