Ten later TESS sectors do not repeat the 25.6-day signal at the published times for TIC 271971130.02

TIC 271971130.02 is a reported Earth-size planet candidate around TOI-715. A prior SPOC test through TESS Sector 69 did not strengthen its signal. We test ten later public sectors, 87–90 and 93–98, with retained measurements from December 2024 through January 2026. We fit a common signed depth at the published times, with a fixed circular transit shape and separate local linear baselines. We do not smooth the measured flux. The candidate depth is −783 ± 452 ppm, compared with 2,075 ppm from the published model parameters. The confirmed planet TOI-715 b is recovered at 4,968 ± 406 ppm. Errors are formal standard errors. Phase controls, event resampling, timing scans, and aperture flux checks support the absence of the tested transit. At known test times, 97.2% of model injections exceed the control 99th percentile. These injections occur after pipeline processing. The result extends the earlier null test. It does not exclude large changes in individual transit times, a different shape, or signal loss before the archived flux stage. The package preserves data, exact source records, code, results, and figures.
