This technical report consolidates the results of Phase 5 of the TSDC (Thermal Selection / Dissipative Cosmogenesis) research program. The study rigorously quantifies the structural robustness of the dissipative selection mechanism under metric deformations, parameter transitions, and adversarial initial conditions. Methodology followed a strict preregistered protocol (WP0) to prevent selection bias. Through extensive numerical integration and global sensitivity analysis (Sobol method), we established the following core findings: Universal Dissipation Floor: A robust operational threshold for the "Hot Big Bang" gate was identified at ₌₈₍ 3. 4 10^-4 (dimensionless), invariant under variations of the critical time scale ₂ₑ₈ₓ 50, 130. Geometric Robustness: The mechanism preserves its selection boundaries under metric deformations up to G = 0. 05, validating its stability within an Effective Field Theory (EFT) context. Kinetic Dominance: Sensitivity analysis reveals that the failure boundary is primarily driven by the kinetic coupling parameter (ST^kin 0. 39), with negligible dependence on the thermal exponent (ST^inf 0. 00). Ignition Hysteresis: We successfully demonstrated the "Cold Start" (Ignition) scenario, quantifying a kinetic hysteresis cost of approximately +50\% in the dissipation rate (₈₆₍₈ₓ₈₎₍ 6. 0 10^-4) required to sustain the lock-in phase compared to the warm baseline. These results confirm that the TSDC mechanism functions as a robust dynamical attractor, independent of specific initial condition priors. This validation serves as the foundational basis for Phase 6, which will apply this framework to the "String Triad" problems: the Swampland Conjectures, Landscape selection, and Moduli stabilization.
