A stable eight hour event model retains 12 period ranges for TOI-3500.02 in four TESS visits at periods of at least one day

We test the period of the known candidate TOI-3500.02 with four public TESS visits. An earlier ExoFOP note reports events in sectors 64, 90, and 101 and a maximum period of 350.3 days. We reproduce the three events and add explicit period exclusions. The events last 7.87 to 8.10 hours and have corrected depths of 7919 to 8204 ppm. For one stable event type with a constant period of at least one day, timing intervals of plus or minus 0.03 days give 350 integer choices. A missing-event test excludes 338 choices and retains 12 timing intervals with central periods from 17.515748 to 350.314957 days. The test requires an eight-hour repeat with at least half the measured depth. It checks data gaps and 41 center shifts from minus 0.10 to plus 0.10 days. All 338 exclusions also pass with original aperture flux. All 300 synthetic events added to published corrected flux pass the recovery threshold. The final QLP target flux retains only 19.3% to 24.7% of the measured aperture-flux depth in these three events. The timing test uses a finite grid and a declared noise allowance. It gives no calibrated planet probability. A known companion at 3.74 arcseconds remains unresolved. These data select neither a unique period nor the host star, and they do not confirm a planet. The package contains source measurements, exact pixel extracts, code, exclusion records, figures, and reproduction instructions.
