 **** Vault service
      - source code is thoroughly deduplicated within the Software Heritage
        archive
      - bulk download of large artefacts (e.g., a Linux kernel release) requires
        collecting millions of objects
      - the *Software Heritage Vault* cooks and caches source code bundles for
        bulk download needs
 **** Tech bits
      - *RESTful API* to request downloads, notifications, and monitoring
      - \url{docs.softwareheritage.org/devel/swh-vault}
 ** Request cooking
