The TOI-6047.01 dip in four TESS sectors exceeds the circular transit limit for the catalog star and radius ratio at most 0.25

We tested an existing catalog warning for TOI-6047.01 (TIC 115451738) with public TESS flux data. We fitted 38 events and 44,259 cadences from Sectors 59, 71, 72, and 73. A shared trapezoid with separate event baselines and sector depths gives a total dip duration of 7.01 hours. The descriptive 95% interval from 300 whole-event resamples is 6.38 to 7.87 hours. The uncorrected aperture flux gives 6.99 hours. With the catalog mass of 0.99 solar masses and radius of 0.9697 solar radii held fixed, a circular transit can last at most 2.83 hours for a body radius at most 0.25 times the star radius. A separate baseline-only test measures flux loss at 1.8 to 2.8 hours on both sides of the fitted center, outside that circular window. The mean loss across four equally weighted sectors is 7.22 parts per thousand, with a 95% event interval of 5.92 to 8.73. The Sector 59 pixel map places the strongest measured loss in the central aperture, but does not identify a unique star. This exploratory case study supports the prior duration warning with actual flux, an added sector, and independent checks. It does not establish a planet, a binary classification, or a false-positive probability. Wrong star parameters, an unresolved host, an eccentric orbit, a larger body, or other variability remain possible. The intervals are conditional on the model and fixed star parameters. The package preserves exact FITS inputs, source records, code, resampling draws, figures, numerical checks, and repeat instructions.
