Embeds the Common document envelope. The manifest itself lives at `manifest.json` inside the archive and does not list itself. Safe archive handling (path-traversal, archive-bomb, and unsupported-content rejection) is enforced by the reference reader, not the schema. DRAFT: not frozen; see specs/bundle/v1/README.md.",
