Word documents have long carried a revision history Documentor can read to work out their order. PDFs carry a different kind of history, embedded in the file itself, and Documentor now reads that too – so PDFs take their place in a version family's sequence instead of sitting in the "order unknown" pile.

• PDFs embed their own provenance: a record, inside the file, of which earlier draft a saved copy was created from. Documentor now reads that directly from the file's own metadata, so a family of PDF revisions can be put in order the same way Word documents already are.
• This signal takes priority over the order Documentor infers from content alone, since it comes from the file itself rather than a guess. When the two disagree – a document's own history looks reverted relative to what its metadata claims – Documentor flags it for a look rather than picking one silently.
• A new "Review order" indicator in the Version Families view surfaces exactly which files triggered that disagreement, alongside the existing order badges.
• The "order unknown" pile shrinks: PDFs, which previously carried no ordering signal at all, can now be sequenced wherever this metadata is present – closing the last major gap in version ordering.
