"""The completion guard itself, not just the name comparison (#2829).

There is a unit test for ``_subtask_names_match``. It is not enough on its own:
reverting ``_completion_belongs_to_queue_item`` to the strict equality that
caused the bug leaves every one of those tests green, because they never touch
the guard. So these drive the guard, with a real archive row behind a real
queue row, on the exact strings that stranded the maintainer's H2D.
