Safe deployments.

Make changes observable and recovery deliberate. A deployment is a change to a service, not simply a completed upload. The guides here connect source revisions, application state, generated assets, and public verification. Use the static workflow for file-based sites, the framework guide for stateful applications, and the GitLab guide for the release record around either one. Before an important change, identify the artifact, target, acceptance test, and recovery boundary. When data can change during a release, explain why restoring an older code package may not be enough to restore a compatible service.
