Can a document tell me what changed?
A revision-aware document can expose differences between related states and present a human-readable change summary.
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.
