> Security considerations: The file is a ZIP archive of audio, images, plain text and an SQLite database. It contains no executable or active content and no external references. Readers must reject entry names outside the rules of the specification (no absolute paths, no '..'), enforce limits on entry count and sizes against decompression bombs, check free space, and verify every entry's size and SHA-256 against project.json. The database is read only by the application with fixed queries. The file may contain the full text of the book being produced and the folder paths of the computer that packed it; it carries no listening data.
