TEST_2000 – Planetary Radiative Equilibrium without Free Parameters

This document presents the Zero-Level Test of planetary radiative equilibrium temperatures within the Tensor Field Dynamics framework. For all eight planets of the Solar System, the canonical equilibrium temperature is computed from observable inputs (solar radius, effective solar surface temperature, planet–Sun distance, Bond albedo) without free parameters. The resulting Teq values fully agree with observations for atmosphereless or internally inactive planets (e.g., Mars). Systematic deviations for Venus or the gas giants are physically explained (greenhouse effect, internal heat). TEST_2000 satisfies zero-fit compliance, is dimensionally consistent and reproducible, providing an audit-proof result for the field-ontological planetary radiation framework.
