An issued entry is a revision, by its revision record's hash and its SVG's digest and derivation's hash (linked) or its file's digest (unlinked), and what it was drawn from; a rendition entry a PDF rendition kept as an asset; a withdrawn entry the drawing's end. Superseded is implied: each issued entry supersedes the one before. The issuer adds entries, in the building; a host never writes it.",
