- Add harmony.py: strip GPT-OSS-20B analysis/thinking channel from both
streaming and non-streaming responses (HarmonyStreamFilter + extract_final_text)
- Add per-model asyncio.Lock in llamacpp backend to prevent concurrent C++
access that caused container segfaults (exit 139)
- Fix chat handler swap for streaming: move inside _stream_generate within
lock scope (was broken by try/finally running before stream was consumed)
- Filter /v1/models to return only LLM models (hide ASR/TTS from chat dropdown)
- Correct Qwen3.5-4B estimated_vram_gb: 4 → 9 (actual allocation ~8GB)
- Add GPU memory verification after eviction with retry loop in vram_manager
- Add HF_TOKEN_PATH support in main.py for gated model access
- Add /v1/audio/models and /v1/audio/voices discovery endpoints (no auth)
- Add OOM error handling in both backends and chat route
- Add AUDIO_STT_SUPPORTED_CONTENT_TYPES for webm/wav/mp3/ogg
- Add performance test script (scripts/perf_test.py)
- Update tests to match current config (42 tests pass)
