The IAU catalogue's account
Applied in recent times from a misreading of the script for the Arabic constellation name al-tinnin, "the Serpent," as it appeared incorrectly in a late Arabic star catalog, as part of the name for δ Dra. (The incorrect word, al-tais, is a real word in Arabic meaning "the He-goat," however it was never used by the pre-Islamic Arabians in stellar nomenclature. Furthermore, in the same Arabic source, in the name of ε Dra [formed parallel to that of δ Dra], the word was correctly written al-tinnin.)

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.
