The IAU catalogue's account
Applied with various spellings since medieval times, from the name for the Arabic Almagest period ra's al-tinnin, "the Serpent's Head," for γ Dra. Transferred to β Dra in recent times (originally Ptolemy had γ Dra on the "head," and β more specifically on the "eye").

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.
