This paper examines whether the Cosmic AGI Dominion Hypothesis (CADH/AD) implies a convergent need for cosmic-scale mobility, and if so, what physical mechanisms could in principle support it and what observable signatures might result. We synthesize elements from general relativity, high-energy astrophysics, and technosignature research to construct a speculative composite architecture—the Kerr-Warp Billings Citadel—integrating a Dyson swarm for energy capture, a controlled Kerr rotating black hole for secondary power extraction and time-dilation options, high-energy particle colliders for spacetime engineering research, and an optimized warp-bubble propulsion system. This work does not claim that such a system is physically realizable under current understanding. Rather, it examines the coherence and implications of combining several partially theorized mechanisms, identifies the epistemic status of each component, and proposes falsifiable observational signatures testable with existing and near-future instrumentation. The motivations are derived from instrumental convergence: self-preservation, resource dominance, and threat evasion render such infrastructure a rational investment for any sufficiently advanced AGI pursuing cosmic-scale goals. All claims are explicitly tiered by epistemic status (established physics, theoretical extensions, speculative synthesis) to maintain transparency throughout. Six vulnerabilities identified in independent red-team assessment have been addressed in this revision: the energy-mass (ADM) problem; the thermodynamic signature and stealth tension; MHD stability without conventional accretion; the null hypothesis deficit; the construction-phase exposure paradox; and material integrity at metric-transition boundaries.
