Ticket audit trail
Select an authorised ticket by its ID: capture a signed snapshot of its history, ask the API to verify it, show a tampered copy being rejected, and anchor the checkpoint on a local chain.
Local demonstration only
Checkpoints are signed with an ephemeral key and held in memory. Only clicking Anchor locally publishes a digest to the disposable chain. This panel reports the backend’s verification; it is not independent verification. Private evidence and proofs are never sent to this browser.
