TESS sectors 80 and 92 recover all 768 GJ 724 b model signals at 2 Earth radii on a fixed eccentric orbit grid

We test public TESS light curves of GJ 724 (TIC 424934357) from sectors 80 and 92. The 2023 planet discovery paper had no TESS data for this star. No signal in our search passes the conditional noise threshold. The largest formal box score in the main search is 9.516, below a threshold of 11.486 from 1000 block sign controls. We add physical transits before trend fitting, with the measured aperture dilution. The main orbit has period 5.101284 days, eccentricity 0.577, periastron angle 33.2 degrees, and stellar radius 0.52226 solar radii. At each radius we test 256 phases at impact parameters 0, 0.5, and 0.8. We recover all 768 signals at 2 Earth radii. We also recover all tested signals at 2.5 and 3 Earth radii. At 1.5 Earth radii, the counts are 256, 252, and 130 out of 256 on the three paths. Added checks vary the trend fit, flux product, and individual orbit or star values. All their signals at 2 and 2.5 Earth radii are recovered. The package has raw data, source records, all trial rows, code, figures, and reproduction instructions. These finite tests give conditional sensitivity. They do not exclude all possible transits or give a probability that the planet does not transit.
