| ## Hugging Face deployment notes |
|
|
| - **Frontend:** [community-security-and-emergency-ma-gamma.vercel.app](https://community-security-and-emergency-ma-gamma.vercel.app/) |
| - **Set Space replicas to 1** — WebSocket camera control, refresh tokens, and live face state are per-container. Multiple replicas cause intermittent 401 refresh failures and face tracking that “stops working”. |
| - **Repository secrets (required):** |
| - `CORS_ORIGINS=https://community-security-and-emergency-ma-gamma.vercel.app,https://rapid-eec43.web.app,http://localhost:5173` |
| - `CEPHEUS_JWT_SECRET`, `CEPHEUS_AUTH_USERS`, `GEMINI_API_KEY` |
| - **Hardware:** Use **CPU upgrade** (or GPU if available). Set `OMP_NUM_THREADS=4` and `CEPHEUS_FACE_WORKERS=4` (already in Dockerfile) so InsightFace uses available CPU cores. |
