Curation

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

GROUND 2026-08-20 · claude-opus-5
Grounded to ENVO:00000232 'fen' (EXACT). Triad-evidence review (#126): GOLD's submitters annotate each biosample with a MIxS ENVO triad, and this concept's path carries 3 INDEPENDENT studies all asserting local = ENVO:00000232 'fen'. That is evidence of a different kind from a label match — what the people who took the samples said the environment was. Study count is what is quoted rather than sample count because 122 of 140 unanimous paths are one study repeating itself; this one is corroborated across 3. The term is claimed only by PREGO's 'fen'. A fen under Soil > Peat is the same wetland PREGO names; grounding merges them. (source concept habitatmech:GOLD.7aa9e7da9a)
