Architecture (State 013 Radius Platform on Kubernetes)

State 013 preserves state 012 C3 runtime while adding Radius application/resource abstractions.

• Inherits architectural baseline from: 012-platform-convergence-c3
• Generated from: system/architecture.model.json
• Canonical flows: ../001-baseline-uncontainerized-parity/system/end-to-end-flows.md

Entry Points

• edge-proxy: http://localhost:8080

Node Catalog

Node	Kind	Label	Notes
developer	actor	Developer	Operates platform/application definitions through Radius.
radius	platform	Radius Control Plane	Application-centric platform abstraction layer.
appModel	component	Radius App Model	Declarative app/resource definitions for TraderX.
cluster	boundary	Kubernetes Cluster	Underlying runtime substrate inherited from state 012.
edge	gateway	NGINX Edge Proxy	Single browser/API entrypoint.
workloads	service	TraderX Workloads	Core services remain functionally equivalent to state 012.

State Notes

• State 013 is an optional child branch of state 012.
• Primary delta is platform/deployment abstraction, not functional API behavior.
