Valid Gaia DR3 SB1 orbits require companions above 0.08 solar masses for TOI-6936.01 and TOI-7590.01

Two open TESS candidates have Gaia DR3 orbit models that require companion masses above 0.08 solar masses. This result assumes that each published single-lined binary orbit is valid. We searched a frozen public list of 8,151 TESS Objects of Interest. Fixed cuts selected four planet candidates first announced after 18 October 2023. For TOI-6936.01 and TOI-7590.01, the mass-function minima are 0.35045 and 0.09215 solar masses. These minima apply throughout a box of three quoted errors in period, velocity amplitude, and eccentricity. They do not need a primary-star mass. The box is a sensitivity test, not a confidence region. All four targets show repeated dips in 12 public QLP light curves. We measured 25 events in both aperture flux and pipeline detrended flux. A timing check with Gaia parameter correlations shows no clear conflict under an approximate conditional Gaussian model. Period and timing matches do not verify the Gaia velocity amplitudes or locate the eclipsing pair within an unresolved multiple system. Independent velocities and spatial eclipse measurements are needed. The package preserves the light curves, frozen catalogue projection, measured results, figures, code, and exact download queries for external Gaia inputs.
