Consistent: a proof from the checkpoint we stored last run to today's verifies. Head only: the log serves no tiles, so no proof can be fetched; a rollback or a second root at a size we already saw is still caught.

Views are checkpoints collected from the transparency.dev distributor and witness.gdbsecurity.com. A split view is two roots at one size.
Tiled CT logs: 71 of 71 witnessed checkpoints reproduce from the live tiles.
Coverage
- Pixel 6 and newer factory images on Google's download page: 963 in the log under their device name, 128 only under generic_system_google, 0 absent.
- Armored Witness firmware: 28 log entries; the leaves hash to the signed root; 0 GitHub release tags with no entry, 0 entries whose commit differs from the tag.
Findings
- warn 128 images logged only under generic_system_google (a payload from the device fingerprint will not verify) since 2026-09-15
