TESS sectors 14, 21 and 41 place the main 3.13-day light loss near TIC 142374123

We test where the main periodic loss of light occurs near the published planet candidate TIC 142374122. A prior SCI timing ledger flags a match with the nearby false-positive entry TIC 142374123. We add source-position measurements from public TESS images in sectors 14, 21 and 41. Each sector has eight usable events. A calibrated pixel response function and a spatial plane place the combined loss 25.14 to 26.44 arcseconds from TIC 142374122 and 1.73 to 2.44 arcseconds from TIC 142374123. The catalog stars are 25.90 arcseconds apart. The result repeats in two cameras and three detector positions. Alternate windows, baselines, fit regions, pointing terms, optimizer starts and image shapes retain the neighboring source region. Removing any one event also retains that region. All 900 whole-event resamples fall closer to TIC 142374123, but these resamples omit common coordinate and image-model errors. The evidence places the main loss off the candidate under the tested image models. It leaves open a smaller transit on the candidate and an unresolved physical source near the neighbor. It does not identify the orbiting object. The package preserves source code, input images, catalog responses, model files, provenance, figures, results and offline reproduction commands.
