A TESS catalog test finds 30 nearby timing matches, and one ground visit does not resolve the TOI-7102 host

We tested nearby TESS Objects of Interest for shared transit times. Of 100 selected pairs, 30 pass a strict central-value test across 3,000 days. They form 28 groups. A fixed-period random-phase control has mean 0.127 pairs. Five matches contain a confirmed or known planet, so a match alone cannot reject a planet. TOI-7102.01 and TOI-7157.01 are the sole strict pair with two planetary-candidate entries. Their catalog depths and brightnesses agree with a shared loss of light. Public records list six ground visits, but only one visit supplies a light curve in these target records. In that visit, the T1 box depth changes from 1.32 to 5.51 parts per thousand across five baseline models with fixed time and duration. Blended apertures and baseline sensitivity prevent a secure host choice. We report no new planet or resolved host. The package supplies frozen public inputs, hashes, pair tables, 40 ground fits, figures, code, and reproduction steps. The timing screen uses catalog central values and does not include parameter covariance or non-linear transit times.
