# Print-page navigation EPUB fixture

This directory contains a deterministic, synthetic EPUB used by the BookTranslator article “How to Preserve Print Page Numbers in a Reflowable EPUB.” It is a publishing-structure fixture, not an output produced by BookTranslator and not a cross-reader compatibility benchmark.

The fixture includes Roman-numbered front matter, Arabic-numbered body matter, a page marker between two sentences in the same paragraph, and an intentionally blank print page. `page-inventory.csv` is the source-of-truth mapping from print labels to EPUB targets. The EPUB contains matching `pagebreak` markers, a `page-list` navigation element, `pageBreakSource` metadata, and the `pageBreakMarkers` and `pageNavigation` accessibility features.

Rebuild it with:

```sh
python3 build_fixture.py
```

Validate the exact output with EPUBCheck 5.4.0. The committed validation report identifies the validator version, the SHA-256 of the checked file, and the exact validator result.

All fixture text and code in this directory are released under CC0 1.0 Universal.
