Add Nexus 6G Core Service with URLLC session management and gNB monitoring

[Copilot]

Implements 6G network infrastructure support via SEP-1 protocol for ultra-low latency neural device control. Enables sub-microsecond latency sessions with credit-based billing and real-time base station monitoring.

Architecture

Core Components:

• NexusEdgePortingProtocol - SEP-1.0 protocol with bc1q account authentication
• UrllcSession - Session lifecycle (STANDBY/ACTIVE/TERMINATED) with NXC billing at 1 credit per 10s
• GnbNode - Base station metrics (latency µs, traffic %, operational status)
• NexusServiceCore - Orchestrates protocol, sessions, gNB fleet, and credit management

Key Capabilities:

• Network metrics: E2E latency, jitter, predictive lead time
• Multi-gNB monitoring with status (OPTIMAL/NOMINAL/HIGH_LOAD/OFFLINE)
• Automatic cost calculation and deduction on session termination
• Millisecond-precision session timing

Usage

NexusServiceCore service = new NexusServiceCore(
    "bc1q4dpjsdcf8pwnduvqermyw5wrzyaqdpttjg3858",
    2_000_000.0  // NXC credits
);

// Add 6G base stations
service.addGnbNode(new GnbNode(
    "ALPHA-001", "Industrial Zone 4", 
    GnbNode.GnbStatus.OPTIMAL, 0.9, 78
));

// Connect and initiate URLLC session
service.connect();
service.initiateUrllcSession();

// Session auto-bills on termination
double cost = service.terminateUrllcSession();

Testing

71 unit tests covering protocol validation, session state transitions, gNB metrics, and service orchestration. Example program in examples/NexusServiceCoreExample.java demonstrates full workflow.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.google.com
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED --add-opens=java.base/java.nio.charset=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED --add-opens=java.base/java.util.concurrent.atomic=ALL-UNNAMED -Xmx2048m -Dfile.encoding=UTF-8 -Duser.country -Duser.language=en -Duser.variant -cp /home/REDACTED/.gradle/wrapper/dists/gradle-8.0-bin/ca5e32bp14vu59qr306oxotwh/gradle-8.0/lib/gradle-launcher-8.0.jar org.gradle.launcher.daemon.bootstrap.GradleDaemon 8.0 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
