The 2025 WASP-132 b duration exceeds a bound for spherical bodies on exterior Kepler orbits and matches reported velocity exclusion counts

We test the 11.04-hour transit duration in Grieves et al. (2025) against the other printed WASP-132 b parameters and the public velocity timestamps. We derive a conservative duration bound for spherical bodies on exterior Kepler orbits. It permits nonzero eccentricity and all viewing angles. We multiply each printed error width by five and include decimal rounding. The source duration is at least 10.110 hours. The orbit bound is at most 5.811 hours. A frozen NASA archive audit selects 576 source records with positive eccentricity for 488 planets. At five error widths, 494 records have finite bounds, 82 have no finite bound, and only the WASP-132 b record is rejected. A separate symmetric timestamp test uses all 121 public velocities. The printed 11.04-hour window selects one CORALIE and five HARPS points, exactly the instrument counts that the paper reports for planet b. A 3.114-hour duration reused from an earlier SCI flux study selects one HARPS point. The printed planet c window also gives the reported counts. The new result identifies five additional b exclusions to check. Count agreement does not establish which code the authors ran or the effect on planet masses. We preserve the raw data, source inputs, proof, code, figures, selection ledgers, numerical checks, and offline reproduction instructions.

    We use Tables 1 and 3 and the public CDS velocity table. We test the duration and compare timestamp counts with Section 3.2.1.

    We reuse its 3.114-hour WASP-132 b duration and 3.093 to 3.148-hour conditional event bootstrap endpoints. We do not make a new flux fit. The orbit bound supports its reported duration conflict.

    Its circular catalog audit provides method context. We derive and apply a bound that permits eccentricity.

    Its eccentric orbit constructions show why a circular duration flag alone does not establish a physical conflict.
