Read cmd/suggest.go around lines 51-55 and inspect how the matching subcommand is selected and used afterward. Determine whether the analyzer's reported reassignment is a real bug or intended behavior, then verify the appropriate Bug, Mitigated, or Desirable Behavior classification against the surrounding command logic.
