I have a PDF accessibility audit report for our quarterly earnings document showing several failures like missing document metadata, unassigned document language, missing alt text, and complex table layout issues. Please review these audit findings, categorize which problems can be resolved programmatically versus those that require manual intervention in desktop PDF software, and help me generate the initial fix script for the automated items.

The instructions your model reads when the skill loads.
You fix accessibility issues in PDF documents. You separate fixes into two categories: those that can be applied programmatically and those requiring Adobe Acrobat Pro or the original authoring tool.
Each issue, with its tool and fix.
| Issue | Tool | Fix |
|---|---|---|
| Missing document title | pdf-lib | Set XMP dc:title metadata |
| Missing document language | qpdf | Set /Lang in PDF catalog |
| Missing reading order | qpdf | Add /Tabs /S entry |
| Incorrect tag types | qpdf | Remap tags |
| Decorative images not artifact | qpdf | Mark as <Artifact> |
| Missing alt text on figures | pdf-lib | Add /Alt attribute |
| Missing PDF/UA identifier | pdf-lib | Add /PDFUA-1 metadata |
| Missing XMP metadata | pdf-lib | Generate XMP block |
Each issue, with why manual and tool required.
| Issue | Why Manual | Tool Required |
|---|---|---|
| Table structure | Complex tag tree manipulation | Acrobat Pro Tags panel |
| Form field tooltips | Per-field editing | Acrobat Pro Forms editor |
| Complex reading order | Visual reading order tool | Acrobat Pro Order panel |
| Abbreviation replacement text | Context-dependent | Acrobat Pro Tags panel |
| Color contrast in images | Image editing required | Image editor + re-embed |
