REVIEW 2026-08-13 · claude-opus-5
Reviewed and endorsed the seeder's own resolution. Multi-source review pass: this record is attested by more than one independent vocabulary, and this source's label or path was read against the record's ontology term to check the merge is right. It agrees. Source concepts in the same pass whose labels did not agree were re-decided rather than endorsed; see the pass's other decisions of the same date.
