A fixed-shape activity model limits intermittent 1000-ppm dips on KIC 11084727 at tested periods

We test intermittent fixed-shape dips on KIC 11084727 with Kepler release 25 data. Quarter 11 sets the shape and epoch and is excluded from repeat counts. No extra corrected-flux event passes the tested score thresholds. We map detectable passages at 6901 trial periods from 10 to 700 days and three depths. A Bernoulli activity model gives pointwise bounds from the number of detectable opportunities. A ten-orbit block model gives weaker bounds. These results depend on fixed depth, shape, timing, noise, and activity assumptions. They are not population rates or orbit exclusions. There is no new planet, comet, or independent telescope confirmation. Code, exact source hashes, data retrieval, derived maps, direct injection checks, and figures are included.
