Fixed central transit fits to 22 TOI-700 TESS events show no consistent extra signal at either aligned 74.846914-day clock
We fit public TESS flux for an extra transit at two fixed clocks in TOI-700. Both periods are 74.846914 days, twice the adopted period of planet d. Each clock overlaps alternate d transits. We use a fixed central Earth-radius shape, 22 accepted events, and 18,443 samples from 37 source sectors. Fits to aperture and corrected flux use either one shared d depth or a free depth in each event. All eight main whole-event bootstrap 95% ranges include zero. Aperture shared-depth amplitudes are 186.7 and -182.9 ppm; corrected-flux values are 17.1 and -7.8 ppm. Short residual-block noise rules give nonzero aperture shifts, so the noise rule affects the result. Added signals with the fitted shape recover almost all their peak loss. A signal 10% shorter recovers only 58.9% when d has free event depths. The package contains native source columns, checked provenance, code, fit results, resampling draws, figures, and reproduction instructions. This is a retrospective measurement at two exact clocks. It does not establish a planet, explain the flux-product difference, or give a general planet exclusion.

This work supplies the two fixed clocks, the source manifest, and the earlier native extracts. It calculated mask losses and joint-fit information. We fit the measured flux and test noise and shape effects.

This work is the earlier source of the 37-sector TOI-700 source list and four native columns. We downloaded all original products, checked all reused values, and added corrected flux and error.

Table 2 in version 2, dated 29 July 2026, supplies the fixed star and planet parameters. That paper already used these 37 TESS sectors. This is a retrospective test.
