RC tags (a v* tag with a prerelease suffix) now publish nothing at all — the release job joins the crates.io job behind the same gate; only final release tags attach artifacts. The tarball loses the 'orig' qualifier: 'orig' is the Debian side's name for the imported upstream tarball (gbp/uscan rename it on import), not something upstream ships. The asset is pkh-<version>.tar.gz over a versioned pkh-<version>/ prefix, the conventional upstream shape.
