If two TOI-2534.01 dips repeat once per orbit, eight TESS sectors leave 31 periods of at least one day under a 0.20% depth rule

Two dips in the TESS light curve for TOI-2534.01 have centres 2827.78129 days apart and durations near 8.3 hours. We test whether one source can give one such dip per fixed orbit. We use eight public TESS sectors and native samples with zero quality flags. There are 2827 integer cycle counts for periods of at least one day. The model requires a flat core depth of at least 0.20%, a duration from 0.32 to 0.39 day, and ingress and egress each no more than 15% of the duration. Each endpoint time can vary by 0.01 day. Other events are tested over a wider range of 0.03 day on each side. An empirical local depth rule rejects 2796 periods and leaves 31, from 46.35707 to 2827.78129 days. Each rejection has a saved window that passes the rule at all sample-membership intervals in that time range. Direct fits check all 2796 saved windows. Eighty inserted dips check the depth estimator. The noise rule has no calibrated rejection probability. The public Sector 103 pipeline report already detects the later deep dip. Our added result tests its possible link to the Sector 1 dip and limits the repeat periods. The fitted depths are 0.491% and 0.435%. Extra light and a Sector 1 coordinate mismatch leave source assignment open. The result does not confirm a planet, a common source, or a unique orbit. The package includes exact source column extracts, headers, source hashes, code, figures, and future event windows.
