The script lists every factory zip on developers.google.com/android/images and looks up each (device, build) in image_info.txt, after checking the entry count against the checkpoint. It also prints the September 2026 images (CP3A.260905.009 for 21 devices and CD1A.260905.001.B1 for cubs, grizzly, kodiak and yogi); image_info.txt was last modified on August 21, so those may just be lag.

# Compare every Pixel 6+ factory image on developers.google.com/android/images
