TESS fits place secondary eclipses near phase 0.5 in three selected TESS Ten Thousand entries with periods of 1 to 2 days

We test large secondary eclipse phase offsets in Table 3 of the TESS Ten Thousand catalog. Of 7936 rows, 773 have a period below two days and a listed secondary time. Four have a calculated secondary phase more than 0.10 from 0.5. We retain all four and fit selected public TESS light curves. We make seven main sector fits. Six fits for TIC 196744614, TIC 306482711, and TIC 470578761 give secondary phases from 0.4982 to 0.5056. Their catalog phases are 0.3758, 0.7720, and 0.2563. TIC 429054424 retains a phase near 0.634, consistent with its printed catalog phase of 0.63. We check alternate flux extractions, local baselines, and symmetric dip shapes. The package contains the full source table, nine FITS files, source hashes, code, fit results, cycle-resampling intervals, and figures. This is an exploratory audit of selected entries and sectors. It does not estimate the catalog error rate, prove circular orbits, or locate the physical source of unresolved eclipses.
