register_measurement_face.Rdface_kind in structure | composition | scale | organism | standsin | none (D2-D3). A standsin row's face_of names the key whose face it
borrows and stands_in_note is the chip's short text; a row that is not
standsin never carries face_of (no borrowed ids on a key that has its
own concept, D3).
