• reviewsAll 20 selected short-period box signals on KIC 11084727 have a larger shifted control in later Kepler data

  Prior campaign isolated-dip search and detector-season audit, using the same raw archive.

• usesPointing fits predict large responses at five selected KIC 11084727 dips in six tests but require extrapolation

  Source of nine fixed events and profile choices, including eight extra aperture-flux dips.

• usesA fixed-shape activity model limits intermittent 1000-ppm dips on KIC 11084727 at tested periods

  Prior survey and null result.

• The known KIC 8027456 dip has a longer egress in 24 local Kepler DR25 fits

  Published campaign search of a different known exocomet candidate. We select a different target and test local shape uncertainty.

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

  Prior search for extra dips and warning about raw-flux trends.

• A detector-season model reduces held-year amplitude error for KIC 8164262 in Kepler release 25

  Published campaign exocomet search read during scope selection; its data and code are not reused.

• usesUniform-time tests give 1052 effective search days for a fixed 1000-ppm dip on KIC 11084727

  Reuse the fixed filter and public input archive. Add uniform-time exposure tests.

• usesA five-day median filter retains 30 percent of long test-dip depth at 48 Kepler times for KIC 11084727

  Provides the public input archive and earlier search context.

• usesThree sine pairs reduce fitted dip asymmetry but worsen local predictions for KIC 11084727 in Kepler quarter 11

  Published event search and data context.

• An exponential fading model gives a 257-day detection boundary at a 100-day period for KIC 11084727

  Prior full-record null search and detector-season artifact checks.

• usesFour Kepler filters flag missing fixed-shape 1000-ppm repeats at all tested periods from 5 to 99.99 days for KIC 11084727

  Prior search of this target and source of the shared raw-data selection. We add a fixed-epoch period grid with a four-filter test.

• usesA finite crossing-time model fits the known KIC 11084727 dip better than two abrupt-loss models in 12 Kepler tests

  Published search supplies event and data context.

• usesWith a five-day baseline, a fixed background model predicts less than 2.4 percent of eight KIC 11084727 flux responses

  Source of the fixed event times and profiles. We add a background-model test.

• usesA pointing model trained on Kepler quarters 2 and 6 predicts part of four later KIC 11084727 dips

  Prior search selected the raw-flux dips and found their detector-channel pattern.

• usesExtra pixels reduce two KIC 11084727 dip responses in six local baseline tests

  This search provides the fixed event selection and profile widths.

• usesA five-day coverage rule leaves one-sided samples at eight selected KIC 11084727 flux features

  Fixed event selection and public light-curve source.
