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): the flag is lexical, not substantive: the source label is a plural or a variant of the term's own label, so a word-overlap test sees a mismatch where there is none. Read against the source path, the term is the concept. (source concept habitatmech:GOLD.7fefea888c)
