The Demon's Hardware: Information-Geometric Bounds on Thermodynamic Computing

Derives information-geometric lower bounds on the energy cost of irreversible computation, extending Paper 4's superconductor analysis to general thermodynamic computing architectures. Proves that the Landauer limit is not a lower bound for systems operating under opacity constraints — opacity imposes a multiplicative energy penalty derivable from the Fisher information geometry. Provides falsification conditions and testable predictions for quantum computing systems. Part of the Void Framework physics-native series (Papers 4, 4B, 4C, 8).
