# Legacy DokuWiki PDF archive

The legacy server recovery performed on 2026-08-03 preserved every PDF exposed by the current DokuWiki media namespaces.

- PDF files: 332
- Total bytes: 417,839,494
- Unique SHA-256 hashes: 297
- Duplicate-content groups: 33, covering 68 retained paths
- Public archive root: `public/media/legacy-dokuwiki/`
- Machine-readable inventory: `docs/pdf-inventory.tsv`
- Publication review: `docs/pdf-publication-review.tsv` and `docs/pdf-publication-review.md`

The original namespace hierarchy and filenames are retained so course context is not lost. Duplicate content remains at each original path intentionally. Each downloaded file passed a PDF file-signature check and Poppler `pdfinfo` parsing.

The TSV inventory has one row per PDF and records:

1. Original DokuWiki media ID
2. Public URL
3. Public repository path
4. Legacy source URL
5. Byte size
6. SHA-256 checksum

The archive contains current media files discoverable through the legacy Media Manager. It does not include deleted historical media revisions. On 2026-08-03, the repository maintainer confirmed that permission had been obtained from the document creators and that all 332 files may be exposed on the wiki. The collection is therefore published and linked from the reader-facing archive page.
