A 9.70-day KOI-2700 box signal falls below a shifted search maximum after a fixed rotation fit

We search Kepler release 25 Q1 to Q17 of KOI-2700 for an additional 0.12-day transit at periods of 2 to 20 days after a fixed stellar rotation fit. The largest corrected-flux box score is 12.07 at 9.70009 days, with depth 271 ppm. One of 20 quarter-shifted full-search maxima is larger, giving conditional rank 0.0952. Aperture flux has score 7.53 at this period and selects another maximum. A wider known-transit mask also selects another maximum. A first-half-only search selects 3.65540 days; its later fixed contrast has conditional rank 0.258. Four ideal injections each at 500 and 1000 ppm are recovered; none of four at 200 ppm is recovered as the largest peak. These tests do not establish a new planet or exclude one at 9.70 days. Time correlation, the mask, fixed duration, small control sets, and absent independent telescope confirmation limit inference. Code, source hashes, aggregate evidence and retrieval instructions are included. External exposure records remain outside the bundle.
