Read answer →Universal Document answer
Why create a new document format at all?
Because modern workflows need structure, revision lineage, machine readability and portable evidence that legacy files do not consistently carry together.
What UD changes
Universal Document treats document state and lineage as explicit information instead of leaving them only in filenames, folders or platform history. That can make the answer inspectable after the file travels.
What it does not prove
Document integrity and provenance do not by themselves establish factual truth, legal sufficiency, identity, regulatory acceptance or organizational authorization.
