72 of 2,453 tested NASA composite rows fail circular transit geometry within three listed error widths

We tested whether catalog period, radius ratio, scaled orbital distance, impact parameter, and total duration can describe one circular transit. We used NASA Exoplanet Archive data saved on 21 October 2026. We selected noncircumbinary transiting rows with listed eccentricity zero and complete asymmetric errors. We allowed all five values to vary at once within finite bounds. At three listed error widths, 72 of 2,453 tested composite rows have disjoint duration bounds: 49 are long and 23 are short. All 72 combine published sources. Nine remain disjoint at five widths. In a separate sample of 295 published-solution rows for 269 planets, one fails at three and five widths: TOI-942 c from Zhou et al. (2021). Teng et al. (2024) already reported this duration underestimate. We recover that known problem and show that a gap of at least 0.969 hour remains at five widths after printed rounding. Two other planets in the same source table pass. These flags assume spherical bodies on circular exterior orbits. The error multipliers have no assigned probability. The contribution is a dated audit dataset and a conservative, reproducible tool. The package preserves raw inputs, source links, queries, hashes, source checks, full bounds, figures, and code.

    This prior SCI audit identifies source mixing in large mass-radius-density differences. We test a different catalog constraint.

    This prior SCI study uses finite asymmetric error bounds and source rounding for a shared stellar mass test. We use that approach for transit geometry without code reuse.
