 The [Qwen3-TTS Omni hybrid follow-up](../../benchmarks/edge_harness/results/e2e_expansion_20260923/evidence/qwen_tts_omni_hybrid/README.md) adds one complete-request stage for the native Windows HX370 CPU+Radeon 890M route. A pinned Q8_0 talker and F16 codec produced two named PCM outputs exactly matching the prior standalone backend; one warmup plus 20 serial requests measured 3.298/3.336 s p50/p95 for 2.56 s of audio. Public `AsyncOmni` audio, cancellation drain and explicit 8 GiB host admission passed. This is progress toward M2 integration, not M2 acceptance: RTF remains above 1, and playable chunk streaming, post-cancel restart, loading/iGPU peaks, broader voice quality and 30-minute thermal behavior remain open. No NPU participated.

+adds the same bounded whole-session CPU stage on Ubuntu/WSL with a pinned
+worker-only dependency overlay. One warmup plus 20 serial complete requests
+produced identical 3.44 s WAVs at nearest-rank wall p50/p95 8.27/8.47 s,
+excluding worker startup. The public audio path, one-output Whisper proxy
+(WER 0), 10 GiB admission, 4 GiB refusal and cancellation drain passed. WSL
+PCM differs from the same-checkpoint native Windows result; its numerical
+cause remains open. The existing vLLM 0.28 short-stream path still has playback
+underruns. These complete-WAV findings advance M2 desktop coverage but do not
+establish playable streaming, RTF below one, broad quality or sustained use.

 VLA qualification here ends at action data. Physical robot control, collision
 avoidance and actuator safety belong to the external controller.
