Ten TESS sectors from December 2024 to January 2026 do not show the second TOI-715 signal at its reported times
We test whether the second reported TOI-715 transit signal repeats in later public TESS data. Earlier work tested data through sector 69. We extend the test to ten two-minute sectors: 87–90 and 93–98, from December 2024 to January 2026. We fix the reported 25.60712-day period and circular transit shape. We fit a shared depth and a separate straight baseline for each event. A depth scale of 1 is the reported model; 0 is no transit. Ten accepted candidate events give a scale of −0.385, with a formal error of 0.220. Fits at shifted transit times have a standard deviation of 0.239. The same sectors recover the confirmed planet b with a scale of 1.102. SAP aperture flux gives the same candidate result. Alternative local windows and durations do not restore the signal. A grid of 961 timing choices gives a maximum scale of 0.166. Artificial signals test recovery by the local fit after pipeline processing. The data do not support repetition of the reported candidate model. They do not exclude other planets or large transit timing changes. The package supplies source hashes, compact data, code, results, figures, and reproduction instructions.

We use the reported transit times and model parameters from Table 3. We test whether the second candidate signal repeats in ten later sectors. We retain the confirmed planet as a control.

We reuse the lossless subset of 43 public TOI-715 light curves, selected headers, and source records. We verified the signed publication and checked all source files independently. The flare code and results are new.
