Möbius values and prime adjunction

n>0 ⇒ ∃!z. Mobius(n,z); Prime(p) ∧ n>0 ∧ p∤n ⇒ μ(pn)=−μ(n)

Define Möbius values from squarefreeness and the parity of actual prime-factor lists, prove unique values, and trace how a fresh prime changes the sign.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved.

Exact mathematical boundary: Mobius(n,z) is positive-domain only, independently defined from squarefreeness and actual prime-factor parity. Signed codes 0, 2 and 1 represent zero, +1 and -1. This family proves values and prime-adjunction laws; the separate Möbius-inversion family supplies the complete G007 endpoint.
