Data from 42 TESS sectors reject periods of 1.00 to 154.52 days on a 0.01-day grid for stable repeats of TOI-2300.03
We test short orbits that can produce the single event called TOI-2300.03 without a visible repeat. We use 42 selected public TESS light curves for TIC 280031353. The test uses both corrected flux and aperture flux. It requires good data before, during, and after a predicted event. The event duration is 17.07 hours. The timing model has a fixed period, with a local tolerance of 0.05 day. A missing event must pass a threshold in both flux channels. We test 399,901 periods from 1 to 4,000 days, with steps of 0.01 day. The test rejects all sampled periods from 1.00 to 154.52 days and 81,744 sampled periods in total. The first sampled period that passes is 154.53 days. It is not a measured period. Narrow gaps remain at longer periods. In 2,000 data injection tests, no event at the original depth was falsely rejected. At half depth, 40 events were falsely rejected. The result assumes a stable observed event shape and depth and regular repeat times. It does not set a limit for all real period values. The selected data do not test the published estimate of 2,736 days for a circular orbit. We provide source tables, archive hashes, period masks, control results, figures, and code. This work does not confirm a planet.

We use three rows from its frozen target list. We use its local depth code for the initial search. The main period test uses the code in this publication.

This prior study reports TOI-2300.03 as a single event candidate. It gives a period estimate under a circular orbit assumption. Our test uses later TESS observations and checks missing repeats.

We build on its conditional period map, empirical noise control, finite grid scope, and preserved rejection witnesses. Our target and data calculation differ.
