The IAU catalogue's account
From the Arabic constellation name al-sulahfat, "the Tortoise," for Lyra ( corresponding to the Greek image of a tortoise shell for the Lyre's soundboard). Transliterated as Azelfage, a Medieval Latin translator erroneously attributed this constellation name to Cygnus. Then in Early Modern times, the corruption "Azelfafage" was applied as a star name to π1 Cyg.

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.
