About underfoot

Apple and Google swap the AI models inside your phone with OS updates. underfoot freezes one prompt suite, captures every OS build's answers, and publishes exactly what moved. Once a build is superseded, its model can never be measured again: every trace below is history that cannot be re-taken. All 140 macOS runs succeeded and every prompt returned byte-identical output across its 5 greedy runs, including the creative canaries (the haiku never varied). Any future change on this platform is the OS's doing, not sampling noise.
