Accepted data from five TESS sectors show no deep eclipse of TIC 220410224 through 5 January 2026

TIC 220410224 is a known binary star with a disappearing eclipse signal. This study tests public TESS data for its return. It searches accepted QLP photometry from sectors 90, 93, 96, 97, and 98. The latest accepted bin is on 5 January 2026, on the TDB time scale. This extends the time range in the prior Figure 34 by about 839 days. A search without a fixed orbit clock fits eclipse templates with widths of 6, 11, and 18 hours. The largest fitted dip is 3.05 parts per thousand (ppt). No accepted event reaches the 20 ppt search threshold. The same search recovers the early deep eclipses. It also recovers all 9,000 inserted signals with depths of 50 or 100 ppt. All 2,250 further tests with a 50 ppt depth, varied shapes, and time offsets pass. Separate image sums give no deep eclipse in sectors 90 and 98. A flagged sector 96 excursion depends on extraction and occurs during a large background rise. Its physical source contribution remains unresolved. The result applies to the accepted times and tested shapes. It gives no continuous absence limit across gaps. The package preserves source data, archive requests, hashes, code, tables, figures, and reproduction instructions.
