+radio-edge-node
+
+This repository contains the containerized supervisor and OP25 instance for the SDR nodes. It manages the local RF workload and synchronizes state with the central C2 via MQTT.

+
+2. Supervisor Logic
+
+The supervisor performs three main tasks:
+
+MQTT Phone-Home: On startup, it sends the Check-In packet to the C2.
+
+Process Management: It wraps the OP25 multi_rx process. If the process dies, the supervisor can report the failure via MQTT.
+
+Metadata Tailing: (Planned) Tailing the OP25 stderr/stdout to extract real-time talkgroup grants for the C2 metadata bus.
+
+3. Deployment
+
+Set your .env variables (NODE_ID, MQTT_BROKER, etc.)
