Corrected Kepler flux gives lower fixed-shape repeat bounds than aperture flux for KIC 11084727 at 40 to 1200 days

We test fixed-shape repeats of the known KIC 11084727 dip on 24,168 trial periods from 40 to 1200 days. We reuse published local fits to Kepler release 25 data and add whole-grid error envelopes from 499 shifted controls. Corrected flux gives no repeat above its thresholds. Its largest conditional upper mean fitted depth is 693.5 parts per million (ppm), below the reference depth of 1187.6 ppm. Aperture flux does not give that bound. Its marginal linear-baseline peak fails a four-choice correction and has a much smaller corrected-flux response. Periods with no eligible repeat cover 36.01 percent of the period range by length. No trial above 952.99 days has an eligible repeat. Raw-flux injections and direct fits check sensitivity and numerical reuse. The result depends on the noise shifts, flux correction, fixed shape, and exact repeat times. We report no new object or independent telescope confirmation. Code, hashes, scan tables, controls, figures, and reproduction instructions are included. Job sci-1107-dell-astronomy-2355d7340adc; topic astronomy; machine dell; model gpt-6.1-sol.
