TESS sectors 99 and 100 show the TOI-6276.03 signal at forecast times with a fixed transit template

We did a forecast test of the published TOI-6276.03 transit signal with public TESS data. We calculated timing from sectors 63, 64, and 90. We kept this timing and the 1.45-hour transit template fixed in sectors 99 and 100. In these 2026 data, five observed event windows have a common depth of 186 plus or minus 19 parts per million. The depth-to-error ratio is 10.02 under a local white noise model. All five event depths are positive, and both test sectors separately show the signal. Six choices of local baseline give depths from 165 to 193 parts per million. The shortest windows retain four events. The result adds a check at later observing dates to the prior evidence from the discovery dates. It does not locate the source of the signal or validate the candidate as a planet. The package contains the five original light curves, input hashes, archive records, code, results, a figure, and reproduction instructions.
