Start with pkg/types/v2/structure.go around lines 63-94 and inspect the deferred calls inside the CommandTests loop, focusing on the analyzer warning about the range variable test. Compare the behavior with the linked commit context; done means deciding whether the finding is a Bug, Mitigated, or Desirable Behavior and leaving the corresponding reaction.
