Research: Radius Platform on Kubernetes

Objective

Define the transition from state 004 to 005 by layering Radius platform capabilities on Kubernetes.

Inputs Reviewed

• spec.md
• plan.md
• tasks.md
• system/architecture.md
• system/runtime-topology.md

Key Decisions

1. Preserve Kubernetes runtime semantics from state 004.
2. Introduce Radius as a platform abstraction without changing core business flows.
3. Keep generated state publishability and compareability with predecessor state.
