Part IV — Uniform Clusters and Configuration

This part shows how to put your own node behind the framework and control how clusters are configured and driven.

It covers the uniform-cluster entry pattern in depth: implementing Application, describing topologies, generating per-node configuration, and driving nodes imperatively outside the scenario runtime.

• Implementing Application — the environment contract for your node
• Topology and Deployment Plans — describing cluster shape
• Ports, Peers, Node Config, and Readiness — per-node configuration mechanics
• Static Artifacts and cfgsync — typed app config to per-node artifacts to backend rendering
• Seeds and Reproducibility — deterministic deployments
• ManualCluster: Imperative Node Control — direct node lifecycle control
• Persistence, Snapshots, and Recovery Testing — state across restarts
