No repeat with the known dip shape exceeds control thresholds for KIC 11084727 on a tested 5-to-40-day grid

We tested a persistent repeat of the known comet-like dip of KIC 11084727 in public Kepler data. The reference quarter sets a fixed shape and event time. A search of the other quarters uses 17,501 trial periods from 5 to 40 days, SAP and PDC flux, and two baseline models. No scan exceeds its threshold from controls made by shifts within quarters. The largest conditional upper mean-depth value is 334.2 parts per million, compared with a reference depth of 1,187.6 parts per million. All tested 1,000 parts per million transit trains pass the threshold at 16 injection periods, including mismatch with the trial grid. These bounds depend on the noise shift model, fixed shape, and exact repeat timing. They do not rule out variable dust, other periods, or an orbiting body. We report no new object and no independent confirmation. The package supplies code, input hashes, depth series, scans, controls, recovery tests, and a retrieval recipe.
