Hugging Face deployment notes

  • Frontend: 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.
