Abstract:</div>

I present a complete proof of the factorization theorem for inclusive hadron production in hadron-hadron collisions. The key improvement over previous literature is the introduction of an explicit unitarity argument formulated in a covariant gauge, applied
consistently to both the collinear and soft sectors. When applied to inclusive hadron production, it reduces the relevant pinch surfaces to those familiar from Drell-Yan factorization. The same technique extends naturally to inclusive hadron production in
lepton-lepton and lepton-hadron collisions, thereby demonstrating the universality of fragmentation functions.</div>
