Grounded to BTO:0006187 'venous blood' (EXACT). Compound-path screen (#12): every search route reads the GOLD leaf alone, but the leaf is only the last step of the path — 'Venous' under 'Blood' means 'venous blood'. Searched on its own it matches nothing (or the wrong sense entirely: 'Hyaline' finds PATO's transparent), which is why the class-level sweep recorded no match. The compound names BTO:0006187 'venous blood' exactly. Read against the full path before deciding. (source concept habitatmech:GOLD.12da3e7025)
