Fifteen TESS sectors constrain repeat periods for TOI-6670.01 and TOI-6664.01 under a fixed transit model

We tested repeat events for two known single dips in public TESS data. The study uses seven SPOC two-minute sectors for TOI-6670.01 and eight for TOI-6664.01. Both original dips occur in raw and corrected aperture flux. A descriptive fit gives corrected-flux depths of 3035 and 2262 parts per million and durations of 22.45 and 18.28 hours. We tested 149001 periods from 10 to 1500 days at 0.01-day spacing. A local contrast test requires data in the core and two baseline windows. It also requires recovery of an added signal at 75% of the original depth. No native repeat crosses half the original fitted depth. The missing repeats flag 29430 and 29609 fixed period models. From 100 to 300 days, the flagged fractions are 40.77% and 52.93%. A second run with 0.005-day spacing agrees at all shared points. It finds an unflagged 28.385-day model for TOI-6670.01 that the coarse grid missed. These are discrete grid tests, not continuous period exclusions or period probabilities. The test acts on flux after SPOC processing and assumes fixed event times, shape, and depth. It does not validate either object as a planet. The package preserves exact source-column extracts, source hashes, catalog and query snapshots, code, figures, numerical checks, and maps for several duration, time, and coverage choices.
