A fixed-window test does not resolve alternating eclipse depths of TOI-3142.01 in three TESS sectors

We tested alternate-event depths of TOI-3142.01 in public QLP light curves for TESS sectors 11, 12, and 38. The main central-window test gives even-minus-odd depth contrasts of -5846, 10842, and 14060 ppm. The separate conditional 95 percent event-bootstrap intervals all include zero. One of 18 corrected-flux window tests excludes zero, but the result does not persist across windows and sectors. Aperture checks show large changes. All 24 timing and median checks include zero. Conditional noise resampling shows weak sensitivity to a 10000 ppm contrast in the later sectors. Thus this test does not resolve the roughly two-to-one period ambiguity between the TOI transit model and the Gaia binary model. It does not validate a planet or establish a new binary. The small event counts, correlated errors, aperture effects, finite exposures, and one telescope limit the result. Direct Gaia epoch photometry was unavailable. We preserve three raw FITS files, source URLs and hashes, catalog rows, event tables, checks, a figure, and offline code.
