02
Fact versus interpretation
Counts, codes and published insertion information are treated as verifiable facts. Value, condition and scarcity language is qualified because markets and physical items vary.
03
Corrections and updates
Each reference carries a review date. Material changes should update the page, sitemap date and public change record while preserving the source behind the correction.
