[SYSTEM] SENTINELAI NODEACTIVE

Always-on intrusion detection node. Packet capture runs as a LaunchDaemon, while the analyzer and monitoring dashboard run in Docker. The ML model is retrained periodically on live baseline traffic.

STACK:Docker Compose, Redis, PostgreSQL, LaunchDaemon, Isolation Forest
NODE:Local (24/7)
ROLE:Threat Detection
[SYSTEM] AI INFERENCE NODEACTIVE

Handles natural language queries in the portfolio terminal (structured commands are processed locally without AI). Load-balanced model routing with automatic fallback between Qwen 3.5 and Qwen 2.5 based on concurrent request load. Exposed via Cloudflare Tunnel with a reverse proxy layer.

STACK:Ollama, Qwen 3.5, Qwen 2.5, Cloudflare Tunnel, SSE streaming
