Indexed from public GitHub and served as immutable, content-addressed versions.

The deterministic audit below grades the latest version, and the same file always earns the same grade.

Notes
- Resolutions: `1K` (default), `2K`, `4K`.

- Do not read the image back; report the saved path only.
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
