Artifacts
“Preserved” means the archive holds the bytes and their digest. “Referenced” means it holds the record of them and nothing more. The archive does not claim a holding it cannot prove.

Column dictionary
The publisher's own dictionary, preserved verbatim. The archive does not reword a schema into its own vocabulary — how the publisher named a column is evidence about the publisher.
