Blueprint change previews

See exactly what will change across your environments before you apply. ryvn plan compares your local blueprint YAML to what's currently deployed and shows you every service that will be created, updated, or replaced — so you can review the full impact before anything runs.

The output walks through each service affected by the change: configuration diffs show exactly which values are changing, new services display their full spec, and secrets stay redacted. You can scope the preview to a single service with --installation, get machine-readable output with -o json, or use --detailed-exitcode to gate your CI pipeline — exit 0 means no changes, exit 2 means changes are pending.
