Six matched fits do not establish a fixed K2SFF and EVEREST depth offset for K2-22 in Campaign 1

We compare transit depths from K2SFF v1 and EVEREST v2.0 for K2-22 in Campaign 1. A linear baseline gives a mean paired difference of 240.5 ppm in 105 orbits, with a conditional 95 percent block range of 99.7 to 395.4 ppm. A quadratic baseline on the same orbits gives 77.1 ppm, with a range of -160.6 to 276.6 ppm. The change between estimates is not resolved. Six fits on a common set of 72 orbits all have ranges that include zero. Shifted-phase controls also give depth-like differences. The evidence does not establish a fixed pipeline offset or scale correction. Both reductions share observations. No new planet or independent confirmation is reported. Code, aggregate results, input hashes and external retrieval steps are included.
