Local flux residuals of KIC 5514277 and KIC 5514383 correlate at 0.80 during the selected Kepler quarter 7 dip

We test a known candidate dip with a distant target at nearly the same detector row. In Kepler release 25 quarter 7, local raw-flux residuals of KIC 5514277 and KIC 5514383 have correlation 0.804 in 92 common exposures. The targets are 76.04 columns and 1.69 rows apart. None of 36 comparison windows reaches this value. Raw-flux correlations remain positive in 12 baseline and quality choices. A linear relation set outside the event predicts only -2.50 to +1.53 percent of the target response in three filter tests. This shows local agreement but does not establish stable transfer or a specific instrument cause. Pair selection was exploratory. The finite controls are not a false-alarm test. We find no new comet or planet and have no independent telescope confirmation. The package includes exact input hashes, source URLs, code, derived data, checks, and reproduction steps.

    We extend its candidate artifact test with a distant same-row target, using its fixed profile and shared observations. The support is limited to a possible shared instrument contribution.
