Evidence boundary
This target indexes Mathlib's uniqueness theorem for prime-factor lists: any list of primes with product n is a permutation of n.primeFactorsList. It does not claim an ordered factorization, a factorization algorithm, a new proof, or a new mathematical result.
This checker record is evidence for the exact formal statement only. It does not establish novelty, transfer a historical acceptance decision, or authorize publication.
