Audit trail explorer

Explore a signed teaching chain in three dimensions. Edit, truncate or replace it, then test signatures, key pinning and retained checkpoints.

How this experiment works

Four records carry actual ML-DSA-65 signatures and SHA-256 links. Verification compares the selected key and latest checkpoint retained separately from the candidate file.

What it does not prove

This OAR-inspired teaching format is separate from production OAR. A valid signature does not prove the record is truthful, complete, fresh or issued by a trusted identity.

Try this challenge

Remove the latest record and disable the external checkpoint. Why can the remaining signatures still verify?
