Passing a set of field names like {'members': {'secret'}} to model_dump(exclude=...) excludes that field from each nested model in a sequence.

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

Passing a bare field set like {'members': {'secret'}} to model_dump(exclude=...) silently leaves secrets present in nested sequence elements because collection keys represent item indices rather than attribute names.
Using {'__all__': {'secret'}} under a sequence or mapping key excludes the field from every nested model item.
Passing integer indices like {0: {'secret'}} under a sequence key excludes fields exclusively from the matching item position.
Passing bare field names to model_dump(include=...) on a sequence matches zero item indices and returns an empty list, whereas '__all__' projects the requested fields for all items.
Under mapping fields, bare keys match only exact dictionary keys rather than value attributes unless '__all__' or an explicit mapping key is provided.
