The IAU catalogue's account
Arabic name al-'Aqrab for the constellation Scorpius ("the scorpion") (e.g. Al Sufi). Application of the transliteration "Acrab" specifically to the pair Beta1 and Beta2 Sco was made by Piazzi (1814) in the Palermo Catalog, and its use spread through the 19th century.

Layer of tradition and ancient-layer signal are not the dictionary authors' judgement but a keyword reading of the entry's wording. “No simple cue found” means exactly that — the parser found none — not that the name is late.
