One-day timing shifts leave missing model repeats at 51.8 percent of tested KIC 11084727 periods

We test whether changes in transit times can hide fixed-shape repeats of the known KIC 11084727 dip. We use Kepler release 25 corrected flux and omit quarter 11 from repeat tests. A map of detection response gives the distance to a time where an added dip is missed. For 1000 parts per million dips, at a score threshold of eight, 92.08 percent of 24,501 tested periods from 10 to 500 days have a missing detectable repeat with no timing shift. This fraction is 51.78 percent when each repeat can shift by up to one day, and 10.31 percent with three days. The map uses sampled times and a fixed shape, epoch, depth, baseline, and noise scale. It is a conditional detection test, not an orbit confidence limit. We report no new object or independent telescope confirmation. Code, source hashes, scan tables, direct fit checks, and figures are included.
