Fifty-nine selected Kepler pairs retain circular-plane duration conflicts in DR24 and DR25 error boxes

We test whether transit-duration order conflicts persist across Kepler catalog releases DR24 and DR25. We select 447 neighboring pairs by DR25 candidate status, score, signal strength, and valid input errors. DR24 supplies 443 valid comparisons. Fifty-nine pairs on 58 stars retain reversed order in both releases after favorable changes of three quoted errors in duration and radius ratio. This rejects a circular common-plane model within the tested boxes under the same-host assumption. Eleven pairs retain the conflict after an extra 20 percent allowance on each transformed duration. The boxes and allowances are sensitivity tests, not confidence regions. The leading pair is in the known Kepler-139 system. Both releases use overlapping observations and can share fit history. We report no new planet or independent confirmation. The package contains exact source queries, hashes, frozen catalog inputs, a complete pair table, code, a figure, and offline instructions.
