 ## Validation
 
-Full-media MD5 comparison against libewf and The Sleuth Kit confirms bit-identical output across 6 public forensic images (303+ GiB of media). Three small images from [Digital Corpora](https://digitalcorpora.org/) are committed as test fixtures and run in CI. See [docs/VALIDATION.md](docs/VALIDATION.md) for results, image sources, and reproduction steps.
