Kepler pixel sums retain the BKJD 1250.96 dip of KIC 3542116 under tested aperture and pointing changes

We test a previously selected shallow dip in Kepler quarter 13 of KIC 3542116. The full measured pixel stamp gives a fixed-template depth of 318 parts per million without pointing terms and 279 parts per million with linear pointing terms. The conditional 95 percent interval is 196 to 364 parts per million for 12-row residual blocks. The dip remains under two other quality masks and eight baseline, window, and pointing choices. A complete transfer of aperture light to measured outside pixels does not explain the fitted net loss. The nearby star gives opposite dip directions in raw and corrected flux and has a crowding estimate of 0.1423. It supplies no clean source veto. The signed pixel map has both gains and losses and gives no reliable source position. We confirm no new planet or comet. These same-telescope tests do not exclude nonlinear instrument effects, stellar variation, or a blended source. The package includes exact raw files, hashes, code, all fit and noise outputs, figures, and offline instructions.
