The lost-light centroid is displaced toward KIC 8758161 in Kepler quarters 5 and 9 of KOI-3006.01

We tested the pixel pattern of the known shallow signal on KOI-3006.01. At the nearby source eclipse times, the lost-light centroid is displaced from the mean-light centroid toward KIC 8758161 by 1.77 pixels in Kepler quarter 5 and 1.23 pixels in quarter 9. Block bootstrap 95 percent intervals are 1.31 to 2.45 and 0.84 to 1.62 pixels. The positive direction remains in time halves, with a wider baseline window, and with linear pointing predictors. Quarter 2 does not resolve the spatial displacement. These results add pixel evidence for the earlier light contamination explanation. The source lies outside the pixel stamp. We do not fit a pixel response function or identify the true binary host. All data are from Kepler, so this is not independent telescope confirmation. No new planet is established. The package includes all used pixel files, hashes, derived event images, code, and reproduction instructions.
