What you get
Built, tested, ready to use.
- 15 command-line tools: manifest, filename check, deterministic ZIP, checksums, licence check, preview page, file counts, PDF pages, image sizes, audio and video metadata, manifest validation, ZIP verification, wording scan, release report
- One release.json holds your promises; release_report.py checks every one and writes Markdown and JSON reports
- ZIP files are byte-identical on every run, so a checksum proves nothing changed between builds
- Python 3.10+ standard library only; pypdf and ffprobe are optional and clearly marked
- Runs fully offline; nothing is uploaded or sent anywhere
- 71 bundled tests you can run yourself, a sample product, JSON Schemas, a manual and a release checklist
