The IAU catalogue's account
ascella ("armpit"). Although it appeared in the 1515 Almagest, the name does not appear to have come into common usage until the 20th century after appearing as Ascella in Richard Hinckley Allen's "Star Names Their Lore and Meaning" (1899).

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.
