The IAU catalogue's account
The formation of this name begins with the Greek constellation name βοώτης (Boötes), which was transliterated and then corrupted in the manuscripts of the Arabic Almagest. One of these corruptions, in turn, was transliterated into Latin as theguius, which became further corrupted into cheguius, ceginus, etc. One form, Ceginus, was applied as a star name by late medieval times, and "Seginus" is its recent spelling.

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.
