Anticipation Series — Paper II: Thermodynamic Dynamics of Anticipation: Dissipation, Relaxation, and the Cost of Staying in Phase

Paper II of the Anticipation Series within the Radial Coherential Dynamics (RCD) research program. ABSTRACT:Paper I established anticipation as counterfactual simulation with thermodynamic cost (L_A = S_avoided / S_sim). Here we develop the DYNAMICS: how anticipatory systems maintain coherence against noise in real time. We formulate anticipation as a driven-dissipative process using Langevin dynamics with an explicit metabolic drive term that breaks detailed balance, derive explicit dissipation rates connected to Landauer's principle, and show how Time-Dependent Ginzburg-Landau (TDGL) dynamics governs relaxation after perturbations. The key result is that maintaining N3 (anticipatory) capacity requires continuous entropy export at a rate bounded below by the Landauer limit. We show that the Landauer cost acts as an external field that converts sharp phase transitions into smooth crossovers, with pseudo-critical slowing down near the crossover temperature T*. No conservative Lagrangian is assumed; the treatment remains fully dissipative. Explicit falsification conditions are provided.
