Corrected 120 s TESS data leave the nominal transits of GJ 1002 c untested in sectors 42 and 70
Can public TESS data test transits of GJ 1002 c after the addition of Sector 70? We inspect the archived SPOC 120 s light curves for TIC 176287658 in sectors 42 and 70. We use the published circular orbit and a central transit of one Earth radius. Both nominal events lack corrected flux. At the published period, both curves also miss the full tested transit for reference epoch shifts between -0.66448 and +3.39272 days. A saved map gives coverage as epoch and period change. Five assumed Gaussian error models leave 65.27% to 84.13% of their samples without contact overlap in either sector. These fractions are sensitivity tests, not orbit posterior probabilities. At known added centers with at least 90% contact coverage, all 290 eligible one Earth-radius signal tests reach a formal signal-to-error ratio of 7. They do not test pipeline signal removal or blind search completeness. A Sector 29 cutout contains collateral pixels outside the science image and adds no stellar photometry. Raw aperture flux exists at both nominal events, with scattered-light quality flags. Simple raw-flux fits give depths that depend on the correction model. We derive no robust transit exclusion from them. The Sector 42 gap was reported in the discovery paper. This contribution adds Sector 70, exact coverage bounds, a parameter map, and raw-flux checks. We find no new planet. Other light curve products, grazing events, eccentric orbits, and a joint orbit posterior remain outside the tested scope. The package preserves data, provenance, code, figures, numerical controls, and instructions for reproduction.

We use the published circular orbit and stellar radius. The discovery paper already reports the lack of a GJ 1002 c transit in useful Sector 42 data. We add Sector 70 and map coverage.
