      "Version: v4.67.0",
      "--repo <REPO> (required): GitHub repository to create the service from; documented add syntax uses `owner/repo`.",
      "--branch <BRANCH> (required): Branch to target. Railway documents this option for `railway service source connect`, but not for `railway add`.",
      "Docs conflict: The official add page lists `-r, --repo <REPO>` but does not list `--branch`; the official service page documents `--branch` only for `railway service source connect`. The release note says `railway add --repo` supports it in v4.67.0."
