This foresight analysis examines potential structural risks posed by the convergence of advanced surveillance AI and life extension technologies on democratic power transition mechanisms over the next 10–20 years. It identifies the erosion of "political death" (regime replaceability) as a core future risk and provides institutional preparation strategies, including geopolitical pressure scenarios. The analysis is inference-based, includes falsifiable conditions, and is intended for policy agenda-setting rather than immediate implementation. Time Horizon: 2025–2045Status: Non-predictive, conditional scenario analysis
