+"""Phase 5 component test: MuseTalk lip-sync + ffmpeg mux.
+
+Verifies the full library-mode per-turn path:
+- Pre-bake a library clip.
+- Generate a stand-in TTS waveform (sine tone).
+- Call ``VideoEngine.generate_speaking_clip`` and get a valid MP4 back.
+
+Writes the resulting clip to ``tests/component/_out/phase5_speaking.mp4``.
+
+Run:
+    docker compose exec voice-chat python -m tests.component.test_05_musetalk_lipsync
