ZTF DR24 data do not resolve alternate event depths for TOI-7349.01 at a fixed 2.980341-day period

We test the reported alternate-depth signal of TOI-7349.01 with independent public ZTF DR24 data. We retain 3356 g and r measurements from 2018 to 2025. We use the fixed TOI period, epoch, and duration. A joint fit has separate band and parity depths, with baseline constants for each survey object identifier and year. Both parity sets show dimming. The equal-band even-minus-odd depth difference is -1146 +/- 2098 parts per million. Its night-cluster 95% confidence interval is -5263 to +2971 parts per million. This interval includes zero and the earlier TESS estimate of -3568 parts per million. A night-level bootstrap and the tested baseline choices give the same unresolved comparison. A conditional calculation gives about 39% detection power for that earlier amplitude under the fitted noise model. This result does not confirm a planet or a stellar binary. The existing 5.960682-day binary sequence remains possible. Source snapshots, code, figures, and checks are included.
