It opens a signed interaction record and shows who acted, what happened, and whether the signature verifies. You can try it in the browser with a sample file or use the CLI locally. No signup, no backend, no outbound fetches.
I built it because logs are useful for debugging, but not great when another team or customer needs something portable they can inspect independently later. I wanted a simple way to open a signed record and verify it with a public key.
The tool is deliberately narrow: it is read-only, verifies structure and signatures, and does not issue records or validate business logic.
Happy to answer technical questions.
