# ophiar

This repository hosts a password-encrypted archive of the owner's consolidated
ophiar research repository, including code, dependencies and retained research
artifacts. The password is distributed separately and is not stored here.
The archive is not directly readable by the Hugging Face datasets viewer.

## Restore

Download all numbered parts and `SHA256SUMS` into the same directory. After the
archive upload is complete, verify and concatenate the parts in numeric order:

```sh
sha256sum -c SHA256SUMS
cat ophiar.tar.zst.gpg.part-* > ophiar.tar.zst.gpg
gpg --output ophiar.tar.zst --decrypt ophiar.tar.zst.gpg
zstd -d ophiar.tar.zst
tar -xf ophiar.tar
```

GnuPG prompts for the password. The encrypted stream uses AES-256; tar preserves
the repository hierarchy and symbolic links. Existing third-party licenses
inside the archive continue to apply; no additional license is granted here.
Historical runtime paths may require relocation before running the archived code.

Do not attempt restoration until `UPLOAD_COMPLETE.json` is present. The README
may be visible while archive preparation or upload is still in progress.
