The IAU catalogue's account

Applied in Early Modern times from its name for the Arabic Almagest period al-zubana al-janubi, the Southern Claw ( of the Scorpion)." The stars of Libra were interpreted by the Baby!onians as "the Claws of Scorpius" (thus forming a much larger Scorpion), and alternatively (perhaps in a more recent stage) they were made an independent constellation, "the Balance." Both these conceptions lived on until the Greeks and, partly, the pre-Islamic Arabians. Previous to Greek influences, the pre-Islamic Arabians used the name al-zubanayan, "the Two Claws ( of the Scorpion}," for the lunar mansion marked by α and β Lib. (Ind-A al-zubanayan is obviously related etymologically to Babylonian zibanutu, but the latter, also marked by α and β Lib, meant "the Balance"). Our modern name is occasionally seen abbreviated as Zuben'ubi".

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.
