Uniform-time tests give 1052 effective search days for a fixed 1000-ppm dip on KIC 11084727
We estimate search sensitivity with 2048 uniform event times across 18 Kepler release 25 quarters of KIC 11084727. We include gaps and rejected samples. A fixed split-Gaussian dip at 1000 parts per million (ppm) passes the stated score rule in 1471 tests. This gives 1051.9 effective search days, with a 95 percent Monte Carlo interval of 1022.5 to 1080.3 days. At 600 ppm, exposure falls to 564.2 days. Coverage rules account for most misses at 1000 ppm. We again find only the known event above threshold. The new result is a uniform-time sensitivity estimate, not a new body or an event rate. Injection takes place after pipeline correction. The test omits earlier pipeline losses and independent telescope confirmation. Code, 12288 injection records, input hashes, source URLs, controls, a figure, and reproduction instructions are included.
