Understanding Your Results

✓ Basic checks passed

The file type is PDF and key metadata is present. This does not prove the document is authentic.

⚠ Review Needed

Some verification checks didn't pass. This doesn't necessarily mean the document is invalid, but some expected metadata may be missing.

ℹ Document Modified

The document has been modified since its original creation. This is common and not necessarily a concern, but the edit timeline shows when changes were made.
