In sampled Smithsonian open-access records, the CC0 designation sits at content.descriptiveNonRepeating.metadata_usage.access for edanmdm records but at content.metadata_usage.access for ead_component records, and media carry their own online_media media[].usage.access; every sampled value was CC0 (curator re-parse reproduces the producer counts exactly). Agents must check the path by record type.

Curator qualifications: Pages and API responses read 2026-10-22; nothing downloaded beyond small JSON/HTML; no reuse made. Range samples of four units only; not a census. Samples are producer work copies (curator re-parsed, not re-fetched).

Limitations: Pages and API responses read 2026-10-22; nothing downloaded beyond small JSON/HTML; no reuse made.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
