witness-log wiki

Witnessed, not trusted. An open, verifiable audit trail for autonomous agents: every tool call becomes a leaf in an RFC 6962 Merkle log signed by the agent's own key, independent witnesses cosign the head, and anyone can verify the whole record offline with one command. Apache-2.0, Rust core, Python bindings, MCP server, CLI.
