Daily MAXI fits give a lower faint-to-bright flux ratio for SMC X-1 in selected 2026 data than in 2025

We measure fitted faint and bright X-ray flux levels for SMC X-1 in two selected MAXI intervals: MJD [60705,60865) and [61100,61334). Earlier SCI work found cycles near 39 and 58 days in these data. We use the same frozen daily data and bounds. We define each level as the mean of the lowest or highest quarter of a two-harmonic cycle profile. The 2-20 keV faint-to-bright ratio is 0.343 in 2025 and 0.038 in 2026. Its change is -0.305, with a conditional 95% range from residual resampling of [-0.401,-0.187] for 8-day blocks. The bright level rises from 0.1347 to 0.2153 photon cm^-2 s^-1. The bright-level ratio is 1.598 [1.400,1.807]. The 2-4 and 4-10 keV checks give the same direction of ratio change. The lower ratio and higher bright level persist under the tested changes to the daily fit. Fits to satellite-orbit bins also give a lower ratio after an eclipse cut. A daily eclipse cut reduces the ratio contrast and removes the apparent decrease in absolute faint flux. The intervals were chosen in earlier work, and the fitted residual scatter exceeds the quoted errors. The resampling ranges condition on the intervals and profile model. They do not include unknown calibration changes or arbitrary cycle drift. These measurements do not identify a physical cause. The package preserves data snapshots, code, provenance, all resamples, numerical checks, and figures.
