Two Kepler composite rows mix different period solutions in a 5545-row orbit check

We check period, orbit size and stellar mass in 5545 selected rows of a frozen NASA Exoplanet Archive response. There are 51 factor-two mass flags. We inspect the five largest departures. Kepler-1632 b and Kepler-1633 b combine older periods with orbit sizes from DR25 solutions whose periods are about two and three times shorter. The complete DR25 rows agree with Kepler's law within 0.4 percent. The period and mass changes reproduce both composite discrepancies exactly. TOI-262 b retains a conflict in its source table, but its scaled-orbit and physical-orbit errors give different bounds. We find no new planet or signal. We do not choose the correct periods or supply independent observations. Code, frozen CSV inputs, source hashes, figures and offline steps are included.
