Masses and Radii from the Seismic Scaling Relations: A Propagated Error Budget for Kepler and TESS Samples

For the great majority of pulsating stars, nobody fits individual frequencies. This paper computes, from stated assumptions and published stellar values, a quantitative budget for seismic masses and radii using Kepler and TESS precision regimes. The headline results are: sM typical = 7.4; sR typical = 2.9; sM poor = 17.3; sR poor = 6.5. Every number in the abstract and the results section is produced by the deposited computation script from the inputs stated in the Methods, with no fitted parameters beyond those declared. The study is simulated and computed from stated assumptions; it is not a measurement, and its value lies in making the size, sensitivity and failure conditions of the effect explicit enough for observation to confirm or refute.
