Before migration, mirror a Git repository to create a local cache for inspection and planning.

neb git mirror <git-repo-url> --mirror-path /path/to/mirror

Convert existing Git history into Nebula-native snapshots. The migration preserves commit topology and authorship.

neb git migrate /path/to/repo --namespace refs/git-migration --lfs pointers

Export Nebula state as a Git repository. The export respects policy decisions from the configured environment.

neb git export origin --target production --execute --worktree /path/to/output

Generate a GitHub pull request plan from a Nebula proposal. This produces branch name, title, and body for manual or automated PR creation.

neb git pr <proposal-id>
