Curation

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

GROUND 2026-08-21 · codex-gpt-5
Grounded to BTO:0003446 'cholesteatoma tissue' (CLOSE). Non-habitat screen review (#108): the path places Cholesteatoma under Human > Benign tumor, and BTO defines cholesteatoma tissue as the expanding keratinised mass in the middle ear. That physical tissue is the habitat; CLOSE records the source's lesion name versus BTO's explicit tissue framing. (source concept habitatmech:GOLD.1c429bbeae)
