Claim. For the number of distinct prime factors, there is tending to infinity and one set of positive integers of natural density one such that through , while
for every sufficiently large real . Thus the normalized counts cannot diverge along any unbounded sequence of real or integer locations.
Covers. The case of the modified Statement of Problem 122, interpreting "almost all" as smallness along one fixed set of natural density one. No monotonicity or everywhere-small width condition is imposed. Other arithmetic functions, including , and the full classification are not settled. The historical unpublished affirmative report's width convention remains unexamined.
Depends on. L34 supplies the complete construction. It uses the , , instance of EPS97 Lemma 1 and Euler's divergence of the prime reciprocal sum. The source statement was checked at the consumed specialization; its proof has no new independent verification here.
Standing. Claimed: the review below is internal to Plasma AI, and the outside sign-off this claim needs is pending. The Plasma AI whole-conclusion examination of 2026-10-14, by a fresh-context adversarial reviewer (GPT-6 Astra), records refutation-failed for the complete modified omega counterexample. A distinct fresh-context grader (GPT-6 Astra) passed that scoped verdict. The canonical statement and core construction match the examined subject.
The grade separately accepts proof defective; statement unresolved for a stronger-width assertion omitted from the canonical proof, and refuted-as-stated for an unused strict-zero clause in the supplied source statement. Neither is a premise of the counterexample. No Lean proof, full source-proof audit or whole-problem solution is asserted.
