The listed TOI-3862 b orbit sizes conflict within five error widths under the adopted stellar radius

The listed TOI-3862 b orbit sizes do not agree with the adopted stellar radius within the tested ranges. We test the exact identity A R = C a, where A is semimajor axis over stellar radius and C converts astronomical units to nominal solar radii. A saved NASA Planetary Systems response gives 2,053 eligible solution rows for 1,459 transiting planets. Seven rows fail within three listed error widths. Four fail within five widths. All seven have equal planet and star reference fields, but this does not ensure a shared fit. We inspect TOI-3862 b in the source paper. Its reported a and adopted R imply A = 5.9344. The paper reports A = 8.848 without a Gaussian process noise model, or 8.885 with that model. Both fail the five-width length test even after allowance for rounding in central values and error widths. The smallest allowed ratios are 1.0215 and 1.0343; a shared geometry requires one. The stellar radius is a prior input, not a published posterior result. Thus the result concerns the listed ranges and does not prove an error in every posterior sample. We fit four public TESS sectors with the published limb coefficients fixed. This diagnostic allows A = 5.9344 and impact parameter 0.764. These values do not give a revised planet solution. The package preserves the archive response, original light curves, source transcription, request records, code, results, and figures. This work supplies a verifiable check of published inputs and a frozen screening dataset.
