Fifteen TESS light curves reject trial periods for TOI-1896.01 and TOI-6666.01 under a fixed transit test

We test whether public TESS data can remove period choices for two known single transit signals. We use four SPOC light curves for TOI-1896.01 and eleven for TOI-6666.01. The test assumes one source, a constant period, the fitted transit shape, and repeat depths of at least half the original depth. Each target has 399,801 trial periods from 2.00 to 4000.00 days, in steps of 0.01 day. An empirical missing event rule rejects 17,759 values for TOI-1896.01 and 37,638 for TOI-6666.01. The first grid values left are 16.98 and 45.94 days. These are test results, not continuous physical lower bounds. The central single event period estimates in Eisner et al. (2021) remain possible. A second calculation agrees at every grid value. Tests with 8640 synthetic signals give zero false exclusions in 2880 trials at the fitted duration. Changes in duration give 56 false exclusions at half depth. A larger noise margin also changes the weaker target result. The package preserves all fifteen source FITS files, exact queries and hashes, code, fitted depths, period masks, injection results, and figures. The focused analysis can run offline. This work supplies conditional period maps. It does not confirm a planet or select a unique period.
