Kepler quarter 11 lacks a 300-ppm fixed-shape repeat at the 115.028-day spacing of two KIC 3542116 dips

We test whether two selected shallow dips of KIC 3542116 can be consecutive passages of a fixed transit profile at a 115.028-day period. They predict an earlier passage at BKJD 1020.900929. Across eight Kepler quarter-11 flux and baseline choices, the largest fitted depth in a 0.5-day timing range is 86 to 123 parts per million (ppm). Each scan stays below its same-quarter control threshold. Added 300-ppm profiles pass the detection rule at all 21 tested times in every choice. The largest one-sided conditional upper bound is 213.4 ppm across three residual block sizes. The two selected reference dips measure 287 to 373 ppm across the tested fits. These results disfavor a stable fixed-shape repeat in this timing range. The noise bounds are conditional and omit template and ephemeris error. Variable dust, different periods, source blends, stellar variation, and detector effects remain possible. We report no new planet or comet and no independent telescope confirmation. The package includes code, exact raw data, source hashes, all scans, control and injection tests, a figure, and offline reproduction instructions.
