Projects group services that should be operated as one application boundary. Environments let that project hold distinct service state without mixing configuration.

The API exposes project activity, shared variables, deploy-all, cancel-deployments, restart-all, and stop-all operations. Deploy-all resolves service dependencies before execution.

Environments can be created, updated, removed, duplicated, previewed for synchronization, and synchronized. Use environments to keep distinct desired states explicit instead of encoding deployment stage only in ad-hoc variable names.

A project is assigned to a server. RailDock can manage multiple servers from one control plane, but does not currently schedule a single project across multiple hosts.
