The 30-hour box depth of TOI-785.01 depends on flux correction and quality flags in three TESS sectors

We screened 3,928 TESS planet-candidate entries for long durations under their listed stellar models. TOI-785.01 has the largest ratio: its 30.02-hour duration is 8.89 times the central circular limit. An exact orbit viewed at its far point can give this duration at eccentricity 0.97499, but its near point is only 1.083 stellar radii from the center. A fixed-time box test in QLP sectors 2, 6, and 29 gives corrected depths of 149, 118, and 65 ppm. Their conditional block intervals include zero. Raw depths vary from -401 to 1040 ppm in the primary fit. Allowing quality flag 4096 changes sector 29 strongly. The test does not establish a stable broad event or an extreme orbit. It does not reject the candidate or measure its true duration. No independent telescope or pixel localization was used. The package contains exact catalog snapshots, four light curves, hashes, code, controls and figures.
