 **whisper.cpp cannot load CW2 at all.** It reads its language count off the vocabulary

 posts raw PCM to it with a bearer token, because audio is the most sensitive thing that
 crosses this seam. The switch is `workstation.stt` in
 `deploy/mavend.json`, and deleting the block sends every utterance to mavsttd.
+**mavgpud runs that service as a second child.** That is not an optimisation. CW2 is a
+ROCm process on the same card, so it registers on the KFD like any contender. Under its own
+systemd unit it made mavgpud evict llama-server every few seconds. That took the

+one owner. Any GPU service added beside this daemon has the same defect, so add it to

 Text-to-speech has not moved and piper on homesrv is still the only synthesizer.
