Kepler positions and 2009–2024 transits link TOI 7017.01 to KOI 1254.01
We test whether the active TESS candidate TOI 7017.01 is the old offset signal at KOI 1254.01. The archived Kepler transit source is 0.025 arcseconds from the TOI Gaia position at a representative Kepler date. The listed formal offset error is 0.067 arcseconds per coordinate. The old Kepler period predicts the TOI catalog epoch to within 13.44 minutes after 1061 cycles. Fits to 18 Kepler and nine TESS light curves retain 247 and 42 events. All 27 file epochs are within 24 minutes of the fixed Kepler prediction. Five analysis settings change any epoch by at most 4.03 minutes. The position and time tests link the two records and give the TESS candidate earlier Kepler data. They do not establish the mass or nature of the companion, exclude unresolved sources, or explain the structured epoch residuals. The package preserves the public source data, queries, code, figures, results, and a fresh reproduction check.
