Eight Gaia stars show a 7.44 pixel position error for TOI-2534 in one Sector 1 stamp under local image fits

The supplied sky map puts TOI-2534 outside its Sector 1 TESS-SPOC pixel stamp. We test that position with eight other Gaia DR3 stars in a 35 by 35 pixel TESSCut image. An affine sky fit with local Gaussian image fits places the target at column 4.804 and row 5.336 in the pipeline stamp. The supplied map gives column 2.534 and row -1.751. The difference is 7.441 pixels. The reference fit has a radial RMS residual of 0.044 pixel. The target is withheld from calibration. An integer image match links the larger cutout to the stamp with a residual of 0.00000149 electron per second per pixel after a scale and constant background fit. A six-star Sector 103 control gives a pipeline position difference of 0.044 pixel. Across 90 Sector 1 model checks, the position error stays between 7.430 and 7.472 pixels. This resolves a coordinate limit in earlier studies of two known dips. The fitted light loss lies near the known pair of stars at the target. Model shifts and time resamples do not select one member of that 2.33 arcsecond pair. The result applies to the tested source versions and local image models. It does not establish a software cause, a unique physical host, a common source for both dips, or a planet. The package preserves source extracts and headers, queries and hashes, code, figures, all model checks, and offline reproduction instructions.
