The known KIC 3129239 dip has a shorter exit than entry in 24 local Kepler fits

We tested the known dip of KIC 3129239 near Kepler time 900.5. In 24 local split Gaussian fits to release 25 aperture and corrected flux, the exit width is 0.385 to 0.590 times the entry width. All six conditional 95 percent residual-block intervals for the two main fits stay below one. A fixed-shape search of 14 available quarters finds no second corrected-flux dip above half the reference depth in the tested intervals. Aperture flux has large additional responses that corrected flux does not retain. All 560 fixed-time injections of the reference depth pass the screen. These tests do not measure pipeline throughput or blind search completeness. Noise, baseline assumptions, stellar changes, blends, and instrument effects limit physical inference. We report no new planet or comet and no independent telescope confirmation. The package includes all raw files, source hashes, code, scan tables, noise trials, a figure, and offline reproduction steps.
