TESS fits show eclipse phase offsets above 0.20 in six tested catalog entries with periods from 2 to 5 days

We tested nine entries in the TESS Ten Thousand catalog. We selected all entries with periods from 2 to 5 days and catalog eclipse phase offsets above 0.20. Fits to 16 archived TESS series show large offsets in six entries. These results pass changes to the local baseline, eclipse shape, flux extraction, and period bound. We estimated uncertainty by removing one orbital cycle at a time. The phase ranges, with the measured uncertainty added, stay above the selected offset threshold in the six representative series. TIC 127140421 has a measured second eclipse phase of 0.78674, with a conditional 95 percent interval from 0.78616 to 0.78732. An exact timing relation gives an eccentricity above 0.46 at its sensitivity envelope, if the eclipses form one central pair in an edge-on Kepler orbit at the adopted period. TIC 265749614 gives a further pair after additive baseline correction, but its interval crosses the selected threshold. Two other entries remain unresolved. This work supplies new phase measurements and a reproducible audit. It does not establish new planets or new binary discoveries. The package includes frozen data, source hashes, code, failed fits, tables, and figures.
