The strongest signal at periods of 0.125 to 5 days in the V1334 Tau TESS aperture changed between 2021 and 2023

V1334 Tau has three published short periods. We test which signal was strongest in later TESS aperture flux. We analyze four full TESS visits in 2021 and 2023, a short visit in January 2026, and reference K2 data from 2017. A search from 0.2 to 8 cycles per day finds the largest peak near 2.02 days in both 2021 visits and near 0.321 days in both 2023 visits. Joint fits with three sine waves give semi-amplitudes of 3.15 and 3.30 parts per thousand (ppt) for the two-day signal in 2021, compared with 2.48 and 1.30 ppt for the short signal. In 2023, these amplitudes are 1.69 and 1.81 ppt for the two-day signal and 4.41 and 4.31 ppt for the short signal. Raw aperture flux, a second extraction in 2023, fixed published periods, a quadratic baseline, native samples, and separate halves retain the change. Conditional residual block intervals retain the sign of the amplitude difference. The short signal is also strongest in the 5.97-day visit in 2026. This is a report of later amplitude order, not new periods. The aperture contains unresolved sources. These data do not identify the source of each signal or its physical cause. The package contains the source FITS data, hashes, code, figures, and offline reproduction instructions.
