Released TESS data and orbital bounds conflict with the reported 11.04-hour transit of WASP-132 b

We search 4,827 transiting-planet rows in the NASA Exoplanet Archive and screen 4,392 rows with usable circular geometry. WASP-132 b has the largest reported duration excess, at 3.484 times the central circular limit. The reported 11.04-hour value also occurs in the cited paper, arXiv:2406.15986v2. The same paper's orbital and stellar-density medians give 3.192 hours by exact contact integration. A conservative eccentric-orbit bound stays below four hours at favorable five-error input corners. Fits to released TESS sectors 11, 38, and 65 give 3.047 to 3.295 hours across 12 sector and baseline choices. All three sectors recover inserted 11.04-hour transits within 0.10 hours. The earlier independent ground-based result is 3.0816 hours. These checks support an error in a reported parameter. They do not show a new long transit or identify the error's exact cause. The TESS reanalysis shares source exposures and uses a simple trapezoid. No raw-pixel test or new observation is included. Code, frozen numeric inputs, hashes, source paths, a figure, and offline instructions are preserved.
