Tri-state icon convention?

I have to design a report with validated information about the data entered. In some fields I have a typical triple state.

Imagine a file. That file belongs to a report model file. When uploading it, it can pass the validation or not pass it. The third state would be that this file model has not been uploaded, but the client would know that as it's not needed.

Let me give an example:

Documents

  • A file added which pass the validation -> & # 10003;
  • A file added which didn't pass the validation -> x
  • The file is not uploaded, so it isn't needed -> ?????

Ideally, Nathan Rabe told me in the answer. In case there is no file, it is not displayed. But the product owner has insisted on it because apparently it is something usual in the sector.

That third state "missing/not necessary" ... there is any standardized or similar icon? I do not see any good example on the web and I can not think of something recognizable.

Edit: the file that is not necessary needs an icon because it is the last step of the validation and the user can not load anything after creating the report.

Edit 2: I reformulated the question because I see language barrier and that dark business logic is giving problems
