Nine fixed profiles show no distinct pre-dip brightening in Kepler quarter 11 of KIC 11084727

We test for a short increase in light before the known day-1076 dip of KIC 11084727 in Kepler release 25 data. Nine exposure-averaged profiles give maximum scaled responses of 0.909 in raw flux and 0.833 in corrected flux. Their descriptive ranks against 102 overlapping same-quarter control windows are 57/103 and 64/103. The central profile gives negative coefficients in all tested baseline and linear instrument fits. An added 100-ppm central profile exceeds a fixed control threshold in only 40/102 raw-flux windows and 38/102 corrected-flux windows. Thus, the test finds no distinct positive signal but has low sensitivity to weak scattering. It does not exclude dust, constrain grain properties, or establish a new body. One telescope, gaps, stellar changes, profile choice, and baseline errors limit the result. Code, exact input bytes and hashes, control fits, recovery checks, a figure, and offline instructions are included.
