 ## Recent Changes
 
+**Raccoon Mission Updates, 2025-11-09**
+
+* 🦝 **Production-ready multiprocess architecture** - 4 uvicorn workers for true concurrency, bypassing Python's GIL
+* 🦝 **Voice auto-detection** - `model` parameter now optional, automatically selects correct engine from voice name
+* 🦝 **Voice cache initialization fix** - All worker processes now properly initialize voice-to-model lookup cache
+* 🦝 **Args initialization fix** - Worker processes now have access to server configuration via DefaultArgs class
+* 🦝 **235/245 voices working** (95.9% hydration success rate):
+  - Piper: 55/55 voices (100%)
+  - XTTS: 6/8 voices (75%)
+  - Silero: 142/148 voices (95.9%)
+  - Kokoro: 32/34 voices (94.1%)
+* 🦝 **Extended `/v1/voices` endpoint** - Returns all available voices with engine metadata
+* 🦝 **Makefile targets** - `make hydrate` (test all voices), `make load-test` (concurrent stress test)
+* 🦝 **Comprehensive docs** - See `docs/CLAUDE.md`, `docs/MODELS.md`, `docs/MIRRORS.md`, `docs/AUDIT.md`
+
 Version 0.18.2, 2024-08-16
 
 * Fix docker building for amd64, refactor github actions again, free up more disk space

 ## TTS Engine Status
 
-### Working
-- ✅ Piper TTS (tts-1) - Fast, 100+ voices, absolute paths working
-- ✅ XTTS v2 (tts-1-hd) - High quality voice cloning, multilingual
-- ✅ Silero TTS (tts-1-silero) - Fast CPU-friendly, 148 voices, 5 languages
-- ✅ Kokoro TTS (tts-1-kokoro) - Lightweight decoder (82M params), 34 voices

+## Known Issues and Solutions (2025-11-09)
+
+### Issue: Worker Processes Not Loading Caches
+
+**Symptom:** Voice auto-detection fails with "Voice 'X' not found in any model" despite voices being configured in `voice_to_speaker.yaml`.
+
+**Root Cause:** When using `uvicorn.run("speech:app", workers=4)`, worker processes spawn as fresh imports and don't execute the `if __name__ == "__main__"` block where caches were initialized.
+
+**Solution:** Move cache initialization to FastAPI's `lifespan` context manager, which runs during startup in EACH worker process.
+
+```python
+@contextlib.asynccontextmanager
+async def lifespan(app):
+    # Startup: Initialize voice caches in each worker process
+    global voice_to_model_cache, voices_cache
+
+    # Build caches from YAML...
+    # (see speech.py:23-81 for full implementation)
+
+    yield
+
+    # Shutdown: Cleanup...
+```
+
+### Issue: Worker Processes Get AttributeError on args
+
+**Symptom:** `AttributeError: 'NoneType' object has no attribute 'xtts_device'` when workers try to access command-line arguments.
+
+**Root Cause:** `args` was parsed in `if __name__ == "__main__"` which only runs in parent process, not in worker processes.
+
+**Solution:** Create DefaultArgs class with sensible defaults that gets used by workers, while parent process overrides with actual command-line args.
+
+```python
+# Default args for worker processes (will be overridden in __main__)
+class DefaultArgs:
+    xtts_device = 'cpu'
+    use_deepspeed = False
+    unload_timer = None
+    # ... etc
+
+args = DefaultArgs()
+```
+
+Then in `__main__`:
+```python
+if __name__ == "__main__":
+    parser = argparse.ArgumentParser(...)
+    args = parser.parse_args()  # Overrides DefaultArgs
+    # ... rest of startup
+```
+
 ## Future Refactoring (Planned)
 
 - Move `speech.py`, `openedai.py`, `audio_reader.py` → `src/`
