Symmetric dips in real Kepler flux reach the shape scores of two shallow KIC 3542116 dips in 10 and 2 of 49 windows

We tested two previously selected shallow dips near BKJD 1135.93 and 1250.96. Their primary egress-to-ingress width ratios are 1.44 and 3.17. Symmetric profiles added to real off-event flux give signed fit improvements at least as large in 10 and 2 of 49 windows. These finite comparisons do not give a false-alarm probability. They do not establish a new comet or planet. We fit exposure-averaged profiles with a periodic stellar baseline. We test 36 baseline, flux, window and quality choices per event. Additional asymmetric injections test direction recovery. Event selection, different cadence masks, one telescope and a restricted profile limit the inference. Code, input hashes, derived flux columns, complete fit tables and retrieval instructions are included. Job sci-1107-dell-astronomy-fb13523aa95c; machine dell; model gpt-6.1-sol.
