- <p>A compact empirical response framework is introduced to organize late-time weak-field dynamics5<br>across rotation-supported galaxies and pressure-supported dwarfs. The method is based on radius-6<br>local inversion of co-located tuples of enclosed baryonic mass, characteristic radius, and observed7<br>circular velocity, yielding an empirical response coefficient that can be compared across systems and8<br>dynamical regimes.9<br>Within the rotation-supported calibration domain, the inferred coefficients populate a tight inverse-10<br>mass ridge over approximately five decades in enclosed baryonic mass, including an independent halo-11<br>scale galaxy–galaxy lensing and satellite-kinematics cross-check at ∼ 200 kpc. The ridge exhibits finite12<br>but structured scatter rather than exact constancy. Extending the same tuple-plane diagnostic to13<br>pressure-supported dwarfs evaluated at their half-light radius increases the dynamic range to more14<br>than eight decades in mass and reveals systematic regime-dependent deviations.15<br>Unlike a universal single-valued radial acceleration relation, the primary empirical benchmark16<br>adopted here is the stability and structured scatter of the tuple-plane ridge across radii, tracers,17<br>and dynamical states. The formulation is explicitly empirical and agnostic with respect to microscopic18<br>interpretation and defines falsification criteria based on slope stability, normalization drift, radial co-19<br>herence, and cross-channel consistency.</p>
