Blue-Green Port Forwarding

JR-deployment-014
The deployment system SHALL route external traffic through a single entry port and forward it to internal application ports, enabling near-zero-downtime deployments. The application SHALL run on internal ports (configurable range, e.g. 5001-5010) while external traffic is routed through the entry port (e.g. 5000).

> _Implementation note (Windows):_ Use netsh interface portproxy for port forwarding.
3 test scenarios

  • Subsequent deployment switches ports atomically JR-deployment-014.2
  • Old application drains after port switch JR-deployment-014.3
