A shared-light model predicts the weaker KOI-1037.01 eclipse in Kepler quarters 2 and 5
We extended a nearby Kepler catalog search to half-cycle offsets and integer period ratios through 10. The fixed DR25 sample adds 12 half-cycle pairs to 707 equal-time pairs. All added pairs have only false-positive labels and an existing contamination flag on at least one member. The added count is not a significant excess over a conditional random-phase control: the mean is 9.09 and the upper-tail estimate is 0.2025. We tested V461 Lyr and KOI-1037.01 in Kepler quarters 2 and 5. A scale set by the deeper eclipse predicts the weaker nearby-target eclipse with SAP residuals of 24 and 47 ppm. PDC and a changed baseline give broad agreement. This supports shared variable light and the existing false-positive label. It does not establish a new planet or a new source association. The package includes input hashes, four light curves, a fixed catalog, code, controls, alternative measurements, and reproduction instructions. No pixel localization or independent telescope data were used.

We reuse the catalog snapshot and sample limits, recover the 707 equal-time pairs, and extend the test.

We distinguish catalog depth scaling from a phase test with light curves.
