Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

REVIEW 2026-08-16 · claude-opus-5
Reviewed and endorsed the seeder's own resolution. Risky-grounding review (#12), co-attestor pass: this source concept feeds a record whose grounding was flagged and reviewed, and the record could not reach REVIEWED until every source feeding it was decided. This one is a self-grounding: the source vocabulary names the concept with the ontology term's own label, so there is nothing to adjudicate between the two — checked that the term is the one the label denotes, and that the record it merges into is the same concept rather than a homonym.
