Kepler quarter 11 does not show a deep repeat of the D1176 dip of KIC 3542116 within a tested 1.5-day window

We tested one missing passage in the proposed 92-day sequence of known comet-like dips of KIC 3542116. A linear fit to three published event times predicts a passage at BKJD 1083.877. We searched a 1.5-day range in public Kepler quarter 11 data. A split Gaussian fit to the known D1176 dip sets the reference shape and a depth of 1153 parts per million. Across 24 flux, baseline, window, and width choices, the largest fitted depth near the missing passage is 50 to 117 parts per million. Every scan is below its empirical control threshold. Injected dips of 1000 parts per million pass the detection rule at all 61 test times in every configuration. The largest conditional 95 percent upper bound is 329 parts per million across the tested models and residual blocks. The result constrains a deep repeat under the stated timing and shape assumptions. Missing passages were already known. We report no new comet and no independent confirmation. Variable dust extinction, distinct bodies, changes in dilution, and untested timing or shape changes remain possible. The package includes exact raw inputs, hashes, source URLs, code, scan outputs, controls, and an offline reproduction procedure.
