Empirical Validation Where governance meets the kill chain. The campaign that validated and extended the framework. Volume II takes the Human-Machine Authority Architecture from theoretical formalization (Volume I) into operational test. The governance machinery is here: the Vertical Alignment Principle that anchors accountability across the kill chain, the Five-Layer Stack that translates strategic policy into tactical authority migration, Cross-Theatre Propagation dynamics, the boundary conditions under which the framework holds, and the simulation architecture that validates it. The Results chapter walks Operation Epic Fury event by event the most complex multi-domain conflict of the algorithmic age across four conflict archetypes simultaneously: counterterrorism, gray-zone operations, asymmetric conflict against missile and drone arsenals, and high-end engagements including autonomous swarm warfare. Eight thousand four hundred and fifteen simulation runs. One hundred and one operational battle reports. Primary-source documentation from CENTCOM, JINSA, and ISW. The framework survives the test but only after extending from three core variables to a family of new governance concepts that Volume III's Discussion makes explicit.
