Three of 429 published circular transit solutions fail the inclination test within three listed error widths
We tested circular transit geometry in a NASA Exoplanet Archive query saved on 21 October 2026. The sample contains 429 published confirmed source rows for 381 planets. Each row lists zero eccentricity and complete errors for orbit size in stellar radii, impact parameter, and inclination. We compared the full input ranges at three times each listed error width, with decimal rounding allowed. Three rows have no circular solution: GJ 3929 b, HD 63935 c, and TOI-2136 b. Their values and errors match the original paper tables. All three still fail when the printed source precision sets the rounding allowance. Two comparison entries from the same tables permit a solution. GJ 3929 b is the only flagged archive default row. An invalid expression that mixes degrees and radians matches the two printed inclinations in the TOI-1696 and TOI-2136 table. This later diagnostic suggests a specific cause to check, but it does not prove a code error. An independent 60-digit calculation confirms all range flags. The result identifies incompatible reported inputs under the listed circular model. It does not establish eccentricity or a new planet. The package preserves the frozen query, source-table values and provenance, all selection decisions, code, figures, and reproduction instructions.
