Nine fixed profiles show no distinct pre-dip brightening at three known KIC 3542116 dips

We test nine fixed positive profiles before the known D992, D1176, and D1268 dips of KIC 3542116 in public Kepler release 25 data. No event has a distinct positive response against same-quarter controls. The primary mean over three quarters is 19.7 ppm in raw flux and 14.5 ppm in corrected flux. The joint nine-profile scores are exceeded by 85.3 and 75.3 percent of sampled control combinations. Added common 100-ppm profiles pass the primary threshold in only 31 to 32 percent of combinations. Thus, the test has limited sensitivity to weak scattering. It does not exclude dust or establish a new body. Linear pointing and background fits, baseline checks, source hashes, exact raw files, code, controls, recovery data, a figure, and offline checks are included. The control libraries overlap and do not give survey false-alarm probabilities. No independent telescope confirmation is supplied.
