The Jenkins et al. (2025) HD 33844 b values fail a Kepler bound under a 0.08 solar mass cap
We test listed minimum masses against radial velocity amplitudes in a saved NASA Planetary Systems response from 22 October 2026. An exact range bound allows unknown orbital inclination and assumes a true companion mass at most 0.08 nominal solar masses. Each input range includes three quoted error widths and conservative decimal allowances. The test retains 1,402 source rows for 940 planet names, including 687 default rows. Two source rows fail. Neither is a default row. For the Jenkins et al. (2025) HD 33844 b row, the listed amplitude spans 27.420 to 34.225 m/s. The mass and orbit allow 70.912 to 206.706 m/s, with a 36.687 m/s gap. The conflict persists at five error widths. The checked preprint Tables F.7 and F.1 contain the same inputs and errors as the archive row. The second flag, HD 33142 c from Bryan et al. (2016), repeats a problem already identified by Trifonov et al. (2022). We preserve that result as a known control. The bound supplies a necessary consistency test under a two-body Kepler model and the stated mass cap. The ranges do not define a joint confidence level. We do not refit observations or infer a new planet. The package preserves the frozen input, provenance, source transcriptions, code, figures, full results, validation, and repeat instructions.

The Giguere et al. HD 11506 b source row is a sensitivity example. Its small extra flag vanishes when decimal allowances are applied. We do not identify a new source error.
