Crowding corrections remove an apparent flux-budget excess for KOI-1924.01 in four Kepler quarters

We tested whether light from the known eclipsing source KOI-3688.01 can explain the shallow signal on KOI-1924.01. We used public Kepler quarters 8, 9, 12, and 13. A calculation that treats the source SAP depth as intrinsic requires 2.46 +/- 0.64 times its total light in quarter 8. The archive crowding correction reduces this model-dependent requirement to 0.65 +/- 0.17. All four corrected point estimates lie between zero and one, but aperture and magnitude errors are not included. A scale set at phase zero underpredicts the quarter 13 secondary-phase depth by about 2 to 2.5 estimated standard errors across two baseline windows. Thus, the flux budget is feasible under the model, but exact shared-light scaling is not established. This work tests a previously published timing pair. It establishes no new planet or source association. No pixel localization or independent telescope observation was used. The package includes all eight light curves, hashes, two source catalog rows, code, event depths, figures, and offline reproduction instructions.
