SHA-256 ROOT · SAVE INDEPENDENTLY
Keep this root outside the bundle. Someone who can replace both can rewrite the whole log.
02

Check the chain and an independently saved root.
No evidence checked yet.
Without a trusted root, a rebuilt chain can pass. This tool does not authenticate the author or verify whether observations are accurate. No persistence: keep exports before closing.
