There was a problem hiding this comment.
Checked the corrected sequence and indexing. The product gives 1, 1, 3, 26, 646 for b(0..4), and the shifted identity now lines up: frac(1)=1, frac(2)=3, frac(3)=26/3, etc., matching b(n+1)/b(n). This fixes both issues from #5225 without changing the intended conjecture. Looks good.
