Corrected Kepler flux shows no fixed-shape repeat of KIC 11084727 on 29,153 covered long-period trials

We test a stable repeat of the known dip of KIC 11084727 on a 40-to-1,400-day grid. Of 35,555 trial periods, 29,153 have a measured repeat passage outside the reference quarter. Corrected flux stays below its control thresholds with two local baseline models. The largest conditional upper mean depth is 810.8 ppm, below the 1,187.6-ppm reference dip. All 22 covered off-grid trains added at 1,000 ppm pass both corrected-flux thresholds. A quadratic raw-flux test crosses its own threshold at 829.68 days, from one passage near BKJD 246.32. The response is much weaker in corrected flux and has no independent confirmation. Gaps leave 6,402 period nodes untested. The limits depend on a fixed profile, exact repeat timing, and shifts within quarters. Pipeline loss is not tested. We report no new object. We extend a cited short-period study and preserve code, source hashes, local depth series, scans, controls, injection tests, and a figure.
