Separate transit fits in TESS sectors 34, 61, and 88 show a longer second interval of nine orbits for TOI-6695 b

We measure three transit centers of the known planet TOI-6695 b in public TESS two-minute light curves from sectors 34, 61, and 88. The two adjacent spans each contain nine orbits. The later span is longer by 103.8 plus or minus 6.8 minutes under the stated local noise models. The contrast cancels any reference epoch and constant period. Independent fits allow each transit center, shape, and local flux trend to change. Residual shifts, two block lengths, other trends and shapes, raw aperture flux, and a second TESS pipeline test the measurement. The sector 88 center is 2460697.59728 BJD TDB, with an adopted error of 3.26 minutes. This event extends the TESS data used in the 2025 discovery study. In these files, corrected QLP flux retains only 4.5 to 21.1 percent of the central flux loss measured in raw QLP flux with a local baseline. The discovery study had already established transit timing changes and an outer planet. We do not claim a new planet, a new cause, or a lasting increase in orbital period. Three transits cannot establish that trend. The package preserves all six input files, source addresses and hashes, code, fitted samples, resampled times, figures, numerical checks, and offline reproduction instructions.
