Known metadata gaps
Recorded explicitly rather than guessed.
- No author is named; the page is institutional.
- No publication or revision date is printed on the page, so the year recorded is the year of retrieval and not a statement by the publisher.
- No artefact is recorded: a product page is not byte-stable, so neither RETAINED nor REFERENCED applies. What the page said on the retrieval date is quoted in the evidence record.
