var preflightCmd = &cobra.Command{
	Use:     "preflight",
	GroupID: "maint",
	Short:   "Show PR readiness checklist",
	Long: `Display a checklist of common pre-PR checks for contributors.

This command helps catch common issues before pushing to CI:
- Tests not run locally
- Lint errors
- Stale nix vendorHash
- Version mismatches

Phase 1 shows a static checklist. Future phases will add:
- --check: Run checks automatically
- --fix: Auto-fix where possible

Examples:
  bd preflight              # Show checklist
  bd preflight --check      # (future) Run checks automatically
  bd preflight --fix        # (future) Auto-fix where possible
`,
	Run: runPreflight,
}

	// Future flags (documented but not yet implemented)
	preflightCmd.Flags().Bool("check", false, "Run checks automatically (not yet implemented)")
	preflightCmd.Flags().Bool("fix", false, "Auto-fix issues where possible (not yet implemented)")

	rootCmd.AddCommand(preflightCmd)
}

func runPreflight(cmd *cobra.Command, args []string) {
	// Check for future flags
	check, _ := cmd.Flags().GetBool("check")
	fix, _ := cmd.Flags().GetBool("fix")
