TESS data show flux loss in three eras at the fixed catalog ephemeris of TOI-2095.03

We test the catalog signal of TOI-2095.03 in 40 public TESS sectors from 2019–2024. We keep the 57.6869-day period, reference time, and duration fixed. Fourteen of 19 covered events pass rules for data coverage on both sides. No event is removed because of its depth. The mean signed depth is 597 ± 55 parts per million (ppm). A bootstrap over whole events gives a 95% interval of 464–724 ppm. Each of three observing eras has a positive mean loss. No event has more than 8.95% of the weight. None of 392 shifted-time controls reaches the catalog statistic, but their spread exceeds the simple noise model. These controls do not give a discovery false alarm probability. A quadratic baseline gives a mean near 587 ppm and no excess scatter under the stated error model. The data do not establish physical depth variation. We preserve exact input columns, source hashes, all coverage decisions, code, figures, and offline instructions. SPOC found this candidate before this work. A recent preprint claims planet validation. This audit adds conditional measurements and noise checks from the same observations. It does not identify the source within the aperture or test that validation calculation.
