  "description": "RFC-09: the self-describing manifest inside a FLUX evidence bundle. The archive is deterministic (sorted entries, zeroed timestamps), so identical bundle directories produce byte-identical archives. Signing is a detached signature over the manifest file bytes (flux-manifest.json), transport-agnostic: ssh-keygen -Y, cosign, or openssl all work. A verifier recomputes every file digest and the Merkle root offline, then replays the reference validator.",
