The IAU catalogue's account
Applied in recent times from its pre-Islamic Arabian name al-ra'i, "the Shepherd". This shepherd, with the sheep he attended (al-aghnam, marked by the various dim stars nearby), and the shepherd's dog (kalb al-ra'i,marked by 28/29 [ρ] Cep), seem to form a complete group of pre-Islamic Arabian figures.

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.
