Abstract

We introduce witness covers for the fiber B_n, proving B_n is an upper set in the divisor lattice. Minimal generators are classified via a primitive-vs-ladder dichotomy for atomic prime-power birth moduli.

Keywords: Fibonacci sequences, rank of apparition, divisor lattices, multiplicative number theory
